Laser-plasma accelerator based radiation sources

Dino A. Jaroszynski University of Strathclyde, Glasgow, United Kingdom

E-mail: d.a.jaroszynski@strath.ac.uk

Abstract

Plasma waves excited by intense laser pulses have been shown to produce not only high energy particle beams, but also high brightness incoherent electromagnetic radiation. We show that diverse radiation sources with unique properties can be developed using the laser wakefield accelerator (LWFA). High quality, sub percent energy spreads beams have been measured for 100-300 MeV energies, and there is good evidence that this can be extended to GeV by controlling injection. A unique property of the LWFA is that it produces ultra-short duration electron bunches. Durations as short as 1 fs have been measured. Furthermore, by controlling self-injection using a plasma density gradient applied over a short length, the bunch duration can be further reduced to attoseconds. These ultra-short bunches are potential sources of pulsed XUV and X-ray radiation, which could be useful as time-resolved tools for applications requiring ultra-short probes. The high energy (100s MeV – GeV) self-injected LWFA beams are also intrinsic bright sources of XUV, X-ray and MeV gamma-ray photons with high transverse coherence, which makes them useful for phase contrast imaging. An unexpected source of very high charge, but low energy electron bunches, arises from the non-injected plasma electrons in the LWFA, which are emitted at oblique angles. These high charge (10s – 100s nC), relatively low energy (1-10 MeV) beams have durations of 100s fs to ps, which makes them potentially useful for pulsed radiolysis, single shot imaging of macroscopic objects, and as sources of THz radiation. We present measurements of visible to XUV (currently 60 – 120 nm) undulator radiation with pulse durations as short as 20 fs. Ultra-short duration pulses are possible because the LWFA bunches have durations of the order of a femtosecond, energy spreads less than 1 % and emittances less than 1 pi mm mrad. We show that by extending the electron beam energy to 1 GeV, 1-2 fs duration XUV pulses with peak powers of several MW per pC can be produced. We also show that the beam quality is sufficiently high to potentially realise a compact free-electron laser (FEL). By increasing the energy to GeV levels, a compact, narrow-bandwidth synchrotron source with peak powers in excess of 1 GW may be possible, without the need to build an FEL. This would make LWFA driven synchrotrons very useful sources of bright, ultra-short duration XUV pulses. Furthermore, by reducing the bunch length to attosecond durations, LWFA based radiation sources may become next generation tools for scientists.

Enabling high-performance biocatalysis

Hans-Jürgen Federsel PhD, Assoc Professor Stockholm, Sweden

E-mail: hansjurgen.federsel@gmail.com Abstract There is a need to develop sustainable and greener processes in order to address excessive generation of waste and recent advances in the field of biocatalysis is a step towards making this possible.1 Enzymes, constituting the catalytic moieties, are right at the center of this approach by virtue of their environmental-friendly performance, biodegradability, and adaptability, enabling chemical transformations with remarkable chemo-, regio- and enantioselectivities. Protein engineering has enabled tailoring of enzymes to deliver the required functionality, increase the catalytic efficiency, alter substrate recognition, and incorporating non-conventional structural motifs. The ability to implement these engineered biocatalysts holds promise for sustainable chemical manufacturing.2 However, several challenges remain a barrier against a more widespread use of biocatalysis including the cost of production of the biocatalyst, difficulties in isolating the intact enzyme from a complex reaction matrix to enable its re-use, as well as the challenge of designing a viable manufacturing process. For this, industry is looking at various technical solutions of which immobilization is seen as perhaps the most promising opportunity.3 Harnessing the synergy between biocatalysis and flow chemistry, the binding onto a support makes it possible to recycle the enzyme and, hence, should give rise to a scenario of reduced cost. The immobilization can, in itself, improve enzyme stability, prevent product contamination by the enzyme benefitting a reduction in demand for downstream work up/purification requirements, and facilitate the use of higher enzyme loadings for shorter processing times. Specifically, the EziG® immobilization platform4 is based on polymer-coated, controlled-porosity glass beads which anchor any protein containing a poly-histidine (His6) tag. This platform offers a standardized solution for targeted immobilization of enzymes onto a carrier. These features of EziG enables biocatalysis to become an accessible, effective, and sustainable choice for developing greener processes.

Designing of non-flammable Sodium-ion batteries for large scale stationary storage systems

Palani Balaya

National University of Singapore, SINGAPORE – 117575 E-mail: mpepb@nus.edu.sg

Abstract Deployment of smart grids using renewable energy (solar and wind power) requires large scale electrical energy storage systems (EESS). Currently lithium-ion batteries (LIBs) are preferred for EESS. High power density LIBs addressing intermittency of renewables uses lithium titanate as anode but is expensive ($800/kWh). Besides, lithium is a scarcity. Sodium, on the other hand, is the sixth most abundant element on the Earth’s crust. Sodium-ion batteries (NIBs) operating at ambient temperature are expected to be durable, safe and inexpensive (about $250/kWh). Regardless of the relatively lower energy density of NIBs, they can be effectively employed in smart grid applications, where the weight and footprint requirement are not severe. Non-flammable sodium-ion cells (18650) fabricated using sodium vanadium phosphate as cathode and hard carbon as anode exhibit energy density close to 60Wh/kg (kg refers to the full cell weight) with impressive 4-5C rate performance retaining 83% of the capacity observed at low rates and about 80% capacity retention at 1C rate discharge after 900 cycles. This safe and inexpensive commercial type sodium-ion cells show relatively higher energy density than the aqueous (non-flammable) NIBs available commercially. We will further present safety parameters such as heat losses and internal resistance of the reported 18650 cell which help future directions to develop thermal management systems for NIB packs for smart grids (100-500 kWh).

Abstract

The rising price of crude oil and depleting fossil fuels have induced the requirement of an alternative, green and sustainable energy to replace petroleum-based resources. Syngas (referring to CO and H2 mixture) has been regarded as an attractive and economically viable energy carrier among other eco-friendly energies. Generally, syngas can be used as feedstock for producing synthetic fuel via Fischer-Tropsch synthesis (FTS) and methanol production. In addition, hydrogen, derived from syngas, can be employed as a stand-alone fuel because of its high energy capacity (120.7 kJ g-1) and zero emissions. Syngas is conventionally produced from steam reforming and partial oxidation of methane in industry. Nevertheless, the main drawback of these processes is the considerable anthropogenic CO2 greenhouse gas emission contributing to global warming. Hence, dry (or CO2) and bi-reforming processes have appeared as promising techniques to generate syngas since these methods not only consume CO2 but also convert it to value-added products. This work investigated the implementation of catalytic reforming processes for various H-containing feedstocks (viz., methane, ethanol and ethylene glycol) on Ni- and Co-based catalysts for producing syngas. The physicochemical properties, catalytic performance and stability of employed catalysts were also examined using a wide range of characterization techniques.

Black carbon: from green environment to green Energy Nishith Verma

Abstract

Themes of this presentation center around the many facets of carbon which our research group has studied over the years. These include the synthesis of relatively older materials such as the hierarchal web of micro-/nano-carbon fibers and micro-mesoporous carbon beads for environmental remediation applications, in particular, for the adsorptive/catalytic removal of common atmospheric air and water pollutants. For example, the metal-doped carbon-based catalytic beads was developed for the first time to treat the effluents on a pilot-plant scale. The project is sponsored by Shell India Pvt. Ltd., Bangalore and the study shows excellent results for complete removal of the COD content (~100,000 mg/L) of the wastewater effluent sample, supplied by the company’s Netherland site, under continuous flow conditions. The catalysts are being developed at IIT Kanpur under joint patents with Shell. Our later studies include the preparation of carbon films in situ dispersed with metal nanoparticles and used as the electrodes for microbial fuel and electrolysis cells. The synthesis of similar electrode materials has paved a way for creating a general platform for developing the non-enzymatic electrochemical biosensors for various analytes in human blood, such as glucose, cholesterol and cretinine. The novelty of this study is to be able to successfully fabricate the electrodes via electrochemical polymerization of the recognition elements for different biomarkers, on the inexpensive transition metal-graphitic carbon-polymer nanocomposite film. Thus, dendritic nanofibers of (poly) methyl orange, (poly) acryloamide and (poly) methyl blue could be densely grown on the carbon substrate, used as the recognition elements for the target cholesterol, glucose and cretinine biomolecules, respectively. The recent most study describes a facile technique to minimize the uptake of Cr(VI) by chickpea (Cicer arietinum) plant in soil using microporous activated carbon microfiber (ACF). Simultaneously, nano-sized carbon nanofibers (CNFs), grown over the ACF substrate, are used as an efficient carrier of the Cu micronutrient from soil to root, shoot and leaf of the plants. The data clearly show that a physical mixture of ACF and Cu-CNF can be successfully used for the simultaneous scavenging of Cr(VI) from soil by adsorption over ACF and increased uptake of Cu by plants using the CNFs as the micronutrient carrier. The talk will summarize our recent strategies on synthesis of evergreen carbon-based nanocomposites for environmental, health and energy applications.

Ram Mohan

Laboratory for Environmentally Friendly Organic Synthesis, Department of

Chemistry, Illinois Wesleyan University, Bloomington, IL 61701 USA Email: rmohan@iwu.edu

Abstract With increasing environmental concerns, the use of greener reagents and methods in organic synthesis has become particularly important. Bismuth(III) salts are attractive from a green chemistry perspective because most bismuth salts are remarkably non-toxic, noncorrosive and relatively inexpensive. For example, several bismuth(III) salts are even less toxic than NaCl. This talk will highlight some synthetic methods that have been developed by undergraduate students using Bi(III) salts as Lewis acid catalysts. These reactions include protection-deprotection chemistry, formation of carbon-carbon bonds and synthesis of a variety of heterocycles.

Emerging technologies for food and medicine safety in resource-limited settings

Basant Giri

Center for Analytical Sciences, Kathmandu Institute of Applied Sciences Kathmandu, Nepal

E-mail: bgiri@kias.org.np Abstract Safe water, food and medicines are basic elements for better life. However, contaminated water, food and low-quality and fake medicines are global problems. Unsafe food and water containing harmful bacteria, viruses, parasites or chemicals cause millions of deaths every year. Similarly, ~10% medical products found in low- and middle-income countries are substandard or falsified causing serious illness or even death in addition to wasting individual’s time, money and health. One of the steps towards intervening the consumption of contaminated water, food and medicines is the detection of contaminants. However, currently practiced well-established analytical techniques such as liquid/gas chromatography, mass spectrometry, polymerase chain reaction, immunoassays etc. used for detection of contaminants are not only expensive, time-consuming and labor-intensive but also require well equipped laboratory facility and highly trained users, making them less applicable in the rural areas or developing countries where resources are limited. Recently, there has been unprecedented rise in the development of cost-effective, easy to use, field based robust analytical technologies for food and drug safety monitoring. In this presentation, I will give an overview of point-of-care testing that are affordable, sensitive, specific, user-friendly, rapid, robust, equipment free and deliverable to the end users helping to make quick decisions onsite rather than relying on time, resource and cost bound central laboratory setup. My presentation will focus on emerging microfluidic methods including paper-based analytical devices for testing contaminants in water, food and medicines. These technologies offer enormous potential for improving food and medicine safety issues in resource limited settings.

Research journey from optical nanoscopy to smartphone microscopy

Bhanu Bhakta Neupane

Central Department of Chemistry, Tribhuvan University, Nepal Kathmandu Institute of Applied Sciences, Kathmandu, Nepal

E-mail: newbhanu@gmail.com Abstract

In last two decades, optical microscopic systems that can provide spatial resolution down to few tenth of nanometer are being explored and in use. As compared to other microscopic counterparts, these techniques are easy to implement, can image a live specimen and allow measurements in various in situ environments. Stimulated emission depletion (STED) is one of the highly explored super-resolution techniques. In the first part of my talk, I will focus on the working principle, design, and applicability of the technique in the study of self-assembly of 200 nm colloidal particles. Our study showed that, as compared to air dried self-assembly, packing pattern in wet environments is very different. Interestingly, we found that packing pattern can be changed by changing the ionic strength of solution. In recent years, low end microscopic systems are being explored as cheaper alternatives for applications, such as disease diagnosis, environmental and food safety monitoring. The later part of my talk will be focused on the design, method development and application of the smartphone based microscopic platform for the determination of (oo)cyst of Cryptosporidium and Giradia in vegetable samples.

Role of escaping sets in complex dynamics

Anand P. Singh Department of Mathematics, Central University of Rajasthan, Bandarsindri,

Kishangarh-305817 (Rajasthan) E-mail: apsingh@curaj.ac.in , singhanandp@rediffmail.com

Abstract Complex Dynamics is the study of analytic functions under iteration. Let 𝑓: ℂ → ℂ be a transcendental entire function. For 𝑛 ∈ ℕ, 𝑓𝑛 denotes the 𝑛𝑡ℎ iteration of 𝑓. Thus 𝑓𝑛(𝑧) = 𝑓(𝑓𝑛−1(𝑧)), where 𝑓0(𝑧) = 𝑧 and 𝑛 = 1,2, …. A family of functions 𝐹 is said to be a normal family, if every infinite sequence in the family has a subsequence which converges locally uniformly. The Fatou set ℱ(𝑓)is defined to be the set of 𝑧 ∈ ℂ, such that 𝑓𝑛, 𝑛 ∈ ℕ forms a normal family in some neighborhood of 𝑧. The complement of ℱ(𝑓) denoted by 𝒥(𝑓) is called the Julia set. Classically the properties of Fatou sets, Julia sets and related topics were dealt with, using this concept of normal families. For a transcendental entire function 𝑓, Eremenko (1989) defined the escaping set as 𝐼(𝑓) = { 𝑧 ∈ ℂ: 𝑓𝑛(𝑧) → ∞ as 𝑛 → ∞ } and proved that 𝐼(𝑓) ∩

𝒥(𝑓) ≠ ∅, 𝜕 𝐼(𝑓) = 𝒥(𝑓) and all the components of 𝐼(𝑓)are unbounded, thus giving a link between the normal families and Escaping sets. He further conjectured that all the components of 𝐼(𝑓) are unbounded. This conjecture of Eremenko, though still not solved, has given rise to a rich development in the field. Here we plan to give some recent developments in this field of escaping sets.

Diheme enzyme MauG: nature’s sniper for long-range electron transfer

S. P. Rath

Department of Chemistry, Indian Institute of Technology Kanpur, Kanpur-208016, India

E-mail: sprath@iitk.ac.in Abstract MauG is a terminal enzyme involved in the biosynthesis of the catalytic tryptophan tryptophenylquinone (TTQ) cofactor of methylamine dehydrogenase (MADH). Although two heme units are physically separated in the enzyme, they share electron efficiently behaving as a single diheme unit. A tryptophan residue, positioned midway between the heme centers, has been postulated to act as a bridge for electronic communications. MauG-catalyzed TTQ biosynthesis is accomplished through radical chemistry and initiated using H2O2 as the oxidant which produces bis-Fe(IV) redox state (Figure 1). As the two hemes are physically separated by 14.5 Å, a hole-hopping mechanism has been proposed in which the tryptophan residue reversibly oxidized and reduced during electronic communication. These attractive features have prompted us to investigate on such diheme enzyme and the results will be highlighted in the talk.

Structure of tellurite glass, anti-glass and crystalline phases by neutron diffraction, high energy X-ray diffraction and Reverse Monte Carlo Simulations

Atul Khanna

Department of Physics, Guru Nanak Dev University, Amritsar-143005, Punjab, India

Email: atul.phy@gndu.ac.in Abstract Tellurite glasses and crystals are technologically important materials which find applications in optical waveguides, zero-stress optic and non-linear devices. TeO2 is a conditional glass former and forms glass under the condition of high melt-quenching rates ~105 K·s-1; while the binary and ternary tellurite systems containing alkali, alkaline-earth, rare−earth, transition and heavy metal oxides form glasses easily at moderate quenching rates (~102 to 103 K·s-1) and have a wide glass-formation range. Tellurite glasses have a dual Te-O coordination of 3 and 4 with oxygens. Te-O speciation in the glass network can be studied by neutron and X-ray diffraction. The coordination of networking forming cations, effects the glass forming ability (GFA) of the material and the latter property is determined by the concentration of network modifiers such as Li2O, ZnO, Al2O3, BaO, PbO, Bi2O3, WO3, Nb2O5, Eu2O3, Nd2O3 and MoO3 in the tellurite systems. Heavy metal oxides such as PbO, Bi2O3 and Nb2O5 when added into TeO2 form highly intriguing anti-glass inclusions of the size of several microns within a glass matrix. An anti-glass is a solid, which has long range order of cations (Te4+, Sr2+, Bi3+, Nb5+ etc.) but these are statistically distributed at their sites while the anion sites are partially vacant. Consequently, the X-ray diffraction patterns of bismuth tellurite, lead tellurite, bismuth niobium tellurite and strontium tellurite anti-glass samples show sharp peaks but their Raman spectra show broad phonon bands very similar to glasses. Several heavy metal oxide tellurite glass systems show an intriguing influence of the melt temperature on the GFA of the material that indicates the possibility of liquid–liquid phase transitions in tellurite systems. In this talk an overview of structure-property relationship studies on several tellurite glass, anti-glass and crystalline materials by Raman and photoluminescence spectroscopy, High energy X-ray diffraction, neutron diffraction, Reverse Monte Carlo simulations and pair-distribution function analysis is presented.

Plasma: fascinating aspects and applications

Hitendra K. Malik Plasma Science and Technology Laboratory, Department of Physics,

Indian Institute of Technology Delhi, New Delhi, India – 110 016 E-mail: hkmalik@physics.iitd.ac.in, hkmalik@hotmail.com

Abstract Plasma can be loosely defined as the collection of charged and neutral particles. This is referred to as fourth state of matter, which comprises ions and electrons almost in equal number. The plasma species, i.e. the ions and electrons, are connected with each other by electromagnetic forces because of which the plasmas show their collective behaviour. However, by applying an appropriate bias, we can play with the ions or electrons of the plasma for the diverse applications of plasmas. For example, we can make the electrons to oscillate for exciting wakefield / Langmuir waves /plasma waves whose field can be used for the purpose of particle acceleration. On the other hand, nonlinear current can be generated by the electrons oscillations at a desired frequency with the application of lasers and this current is employed for the generation of Terahertz (THz) radiation. Plasmas have also been used for producing Free Electron Lasers, X-rays and other radiations. We have developed theories for the particle acceleration and THz radiation generation with a focus on the laser / microwave pulse profile for realizing the schemes with their higher efficiency.

If we look towards the role of plasma to nanoscience and nanotechnology, we should focus on plasma-material interaction, where cold plasma processing is an important technology in the field of material science. This is being widely used in semiconductor thin films, ceramics, and nanotechnology for deposition, synthesis, sputtering, sintering, and etching. Plasmas are employed in semiconductor manufacturing for etching features and vias, depositing metals to make interconnections, and cleaning of wafers. Plasmas used for etching are electrically driven by either capacitive coupling or by inductive coupling. We have explored the inductively coupled plasma interaction with two compound semiconductors, namely GaAs and GaN.

Plasma can also be employed for the purpose of surface hardening / nitriding of steels by diffusing elemental nitrogen into the surface of steel up to hundreds of nanometers. This process is used to treat different kinds of products for automotive, aerospace, railways, biomedical industries, etc. By means of a glow discharge in a gas of N2 and H2, with the steel (the cathode) at a temperature 500°C, N can penetrate the surface and diffuse into the steel. Depending on the process parameters and the steel compositions, a diffusion zone is formed, where N penetrates more than a half mm into the steel. A

surface compound zone is also formed on top of the diffusion zone with the thickness in the micron range. We have established a hot cathode arc discharge plasma nitriding system for treating different steel samples, where the plasma generation and work piece parameters can be monitored independently to optimize the process. In the present talk, different aspects of plasma-material interaction, laser/microwave-plasma interaction etc. will be discussed in order to uncover various applications of plasma. Innovation Toward Green Future: Natural-product-inspired Synthesis of Small Molecules of Biological and Industrial Relevance

Arun K. Sinha

Medicinal and Process Chemistry Division, C.S.I.R- Central Drug Research Institute, Lucknow 226021, UP.

E-mail: aksinha08@rediffmail.com Abstract Nature is an irrefutable source of inspiration for the discovery and development of potent biologically active compounds. Some small molecules like phenolics and indole based heterocyclic compounds have drawn great interest from the scientific community as they are associated with wide range of biological activities including anticancer, antibacterial, antifungal, anti-inflammatory and antimalarial etc. However, exploration of these molecules is severely hindered by their insufficient percentage in their natural resources, difficult isolation procedure, limiting trials for wider applications besides their tedious synthesis involving protection-deprotection strategy. The shortcomings of the prevalent methodologies have provided a fresh stimulus to develop a strategy based on Green Chemistry with minimum number of steps, atom economy and waste minimization besides being devoid of protection-deprotection steps. Our group from noticeable time has been working on such green methodologies for synthesis of various phenolic based bioactive molecules like FEMA-GRAS approved 4-vinylphenols, stilbenoids (symmetrical/ unsymmetrical, distyrylbenzene and octupolar stilbenes) and stilbene-chalcones/stilbene-cinnamate hybrids and their biological evaluation. Very recently, our group have developed a pot-economy synthesis of salvionalic acid mimicking molecules which have shown superior antagonistic profiles against the glioma C6 cell line that causes one of the most lethal and malignant forms of brain tumors. The details of synthetic protocol, biological and industrial relevance of natural and non-natural phenolic compounds and indole based heterocyclic compounds will be discussed during presentation.

E-mail: goswamirl@neist.res.in Abstract From the time immemorial colloids and gels are contributing to the different aspects of pre-industrial and post-industrial human development immensely. They may be for the formulation of improved drug dispersions, toothpastes, tomato sauces, inks, paints, gums, clay gels etc. Clay based colloidal dispersions finds important use in a number of applications in ceramics, construction and building industry, pesticide and insecticide formulations, catalysis and oil well drilling. The design and performance of an oil well drilling fluid especially needs an intricate understanding of the clay water interactions, structure of clays, the influence of physico-chemical conditions of geological formulations, the stability of added additives etc. Slight changes in these conditions can cause unpredictable and significant changes in the drilling fluids behaviour. Each rig site drilling fluid data therefore is highly important for oil industry. Bentonite and Sepiolite are two important swelling clays which are central to any new drilling fluid design. Various types additives find various applications with these clay-based fluid compositions. CSIR-NEIST has developed some Layered Double Hydroxide (LDH) based inorganic viscofier suitable for a Low Solid Drilling Fluid like system having prospect in modern horizontal drilling. Further, as a spin off the of the understanding of LDH-Clay interaction newer devices for the control of environmentally toxic gases like N2O, SO2 and H2S has also been developed.

Ferrites: a microwave absorbing material

Sachin Tyagi Central Scientific Instruments Organization, Chandigarh

E-mail: sachintyagi.iitr@gmail.com

Abstract Microwave absorbing materials have become the essential part of defense system for their contribution to survivability of air vehicle. Like defense, these materials are equally important in industries for use as a commercial product for the electromagnetic interference (EMI) shielding. EMI is a specific type of environmental pollution which is caused by the extensive use of electromagnetic (EM) waves in wireless communications. The use of magnetic, non magnetic and composite of magnetic/non magnetic materials in polymer resin matrix system has become a subject of interest in engineering applications due to potential changes in physical, chemical, magnetic and dielectric properties of nanocomposite. These changes in the properties come from unique morphology, increased surface area, exchange interaction existing between hard and soft magnetic phases and quantum size effect associated with nano size particles. In present research work, different types of ferrite materials comprising of soft ferrite like NiFe2O4, ZnFe2O4, hard ferrite like BaFe12O19 and SrFe12O19 and their composites are synthesized by different chemical routes methods. All the developed materials were characterized for their crystal structure determination, morphology, thermal stability, magnetic behavior, dielectric and reflection loss measurement using XRD, FESEM/TEM, DSC/DTG/TG, VSM and VNA respectively. A microwave absorbing medium is developed by optimizing the developed material for large microwave absorption and higher bandwidth in X band for stealth application.

Room temperature ferromagnetism in MoO2 and TiO2 thin films: d0 magnetism

Ravi Kumar

Hamirpur 177005 (H.P.) E-mail: ranade65@gmail.com

Abstract Recently, it has been reported that the nano-particles of most of the metal oxides are showing ferromagnetism irrespective of the presence of partially filled d or f electrons. Such type of results are really very interesting to understand the new way of understanding the subject of magnetism. It was general believe that the origin of magnetism is due to size effect of these oxide materials. It is very hard to believe that how the magnetism can be obtained without the presence of electrons in localized orbital (d and f orbital). To understand this phenomenon, we have investigated the thin films of MoO2 and TiO2, which are generally non magnetic in their bulk form. We observed the ferromagnetism in thin films of these materials. To further understand such phenomenon we have performed detailed investigation using x-ray circular magnetic dichroism (XMCD) x-ray linear dichroism (XLD) experiments. From the experimental observations and our analysis we conclude that the origin of ferromagnetism in such type of materials is due presence of orbital anisotropy. We have generalize that under surface state strain in materials (nano-particles or thin films) orbital anisotropy is generated and give rise to weak ferromagnetism.

Small-Angle Neutron Scattering from Nano and Biomaterials

V. K. Aswal

Solid State Physics Division, Bhabha Atomic Research Centre, Mumbai 400 085

E-mail: vkaswal@barc.gov.in Abstract Small-angle neutron scattering (SANS) is a powerful technique in the study of nanostructured and biological and systems as for most of these systems their 3D structure have a length scale in the range 1 - 100 nm [1]. The major advantage of the method lies in its ability to provide structural information about partially or completely disordered systems. SANS allows to study the structure of native particles in near physiological environments and to analyze structural changes in response to variations in external conditions. Both structure as well as interaction in these systems can be determined by SANS. The applications cover extensive studies of different types of nanomaterials (e.g. nanoparticles, fullerenes, dendrimers and composites) and biomolecules (e.g. proteins, lipids, nucleic acids, macromolecular complexes and polyelectrolytes) as well as their conjugates. Nanomaterials and biomolecules possess a specific shape and charge, which regulate and control their functionality and stability. The particles in aqueous solution are known to interact through different interaction forces [2]. Different phases in any of these systems are preceded and followed by structural changes among them, which can be induced simply by varying temperature or neutralizing the charge on the particle by salt or breaking the water structure by urea [3-12]. The contrast variation either by deuterating the particle or solvent is widely used for the study of multi-constituents systems. This talk will present some of our recent SANS studies of evolution of structure and interaction of some of the nanomaterials and biological systems in different phases.

Abstract In the childhood, we heard a story about the tortoise and the rabbit, the speedy and overconfident rabbit fell asleep in the race, while the turtle won the race being “slow and steady”. That may have been true in stories, but in real life slow and steady won't get you out of the entrance because everyone getting faster and smarter in today's challenging business environment. That’s why, the best organizations all over the world are inventing powerful new source of competitive advantage. It's called supply chain management (SCM) and it involves all of those integrated activities that make available product to market and create satisfied customers. To remain competitive, organizations must hunt for new solutions to important Supply Chain Management issues such as modal analysis, load planning, route planning, distribution network design and forward and reverse logistics. Within the organization, the supply chain management refers to a wide range of functional areas such as manufacturing, purchasing, inbound and outbound transportation, physical distribution, warehousing, and inventory control into a unified package. Production planning and scheduling, forecasting, order processing, and customer service all are part of the process as well. Importantly, it also embodies the information systems so necessary to monitor all of these activities. The current talk discusses the nature and role of Supply Chain Management within the organizations and out of the organization as well. It brings to light the reasons why SCM is necessary for every organization and explains why it is required and what are the application and issues dealt with the same.

Electrochemical Immunosensors for Civil & Defense applications

V. Kameswara Rao

Advanced Centre of Research in High energy materials (ACRHEM), University of Hyderabad, Hyderabad 500046, Telangana, India

E-mail: vepakrao@uohyd.ac.in

Abstract Diagnosis of diseases is normally done by various techniques such as ELISA and Diagnostic kits which include lateral flow assay etc. The sensitivity and detection time are the main issues in the standard techniques. Particularly on-site detection becomes difficult. Hence it is necessary to develop sensors that are cheap, portable, highly sensitive and require no expert. Similarly, there are several Biological warfare agents which are pathogens and toxins which also need to be detected at remote sites. Hence, there is a need to develop detection systems. Immunosensors are a type of biosensors which exploit the affinity between and pathogens and their antibody. This interaction is revealed by using a probe attached either to pathogen or antibody. The probe is chosen depending on the type of transduction method used in the sensor. We utilized electrochemical and chemiluminescence principles for detection of pathogens and toxic proteins. Various types of electrodes such as screen-printed electrodes, paste electrodes besides the gold and glassy carbon electrodes were compared. In order to improve the immobilization of the antibodies we used metal and metal oxide nano particles. The nano materials used were able to improve sensitivity. The probes used include enzymes, quantum dots and redox probes. We worked with Ricin, Brucella abortus, Plasmodium falciparum histidine rich protein-2, Typhoid antibodies and staphylococcus enterotoxin B. In general, we tried to develop a cheap electrochemical immunosensor platform that can be used for detection of any pathogen. The immunosensor that has stable probes, less human intervention, cheap and easily portable is likely to be accepted by users.

Phagwara-144411, Punjab, India E-mail: niti.kant@lpu.co.in

Abstract The interaction of laser with plasma gives rise to several novel relativistic nonlinear optical effects. Higher harmonic generation is an important nonlinear effect. High power ultrafast lasers use chirped pulse amplification technique to reduce duration of pulse and hence produces pulses of extremely high power densities which in turn oscillates electrons in the medium. The velocity of oscillating electron beats with applied frequency giving rise to higher order harmonics. This paper presents the idea of generation of second harmonic waves with the ultra-fast lasers in plasma, phase matching conditions of second harmonic generated by self-modulation under paraxial approximations and its application in imaging microscopy.

Sciences Lovely Professional University, Phagwara, Punjab – 144411

E-mail: rakesh.21797@lpu.co.in Abstract In this paper, we intend to study the plasma profiles at the exit of an ion gun. Ion guns are close to the electrostatic ion thrusters. The ions are allowed to escape through an electrostatic potential difference of 100 V. The plasma density is considered to be a variable. A code is employed, based on Particle-in-cell method to study the plasma behaviour at the exit of the ion gun. The code is written in 2D (r, z) coordinates. Initially, the ion velocities are sampled out of a Maxwellian distribution. However, the velocity evolves under the electrostatic potential difference with time. Computationally a sparse gridding is assumed. Various plasma profiles such as the density of ions and maximum z-directional velocity are calculated. The maximum z-velocity has been found to be on the order of 20 km/sec.

PHY04-Structural and electrochemical studies on V2O5, WO3 and multilayer films fabricated by reactive DC magnetron sputtering

Ravish Kumar Jain and Atul Khanna* Sensors and Glass Physics Laboratory, Department of Physics, Guru Nanak Dev University, Amirtsar-143005, Punjab, India.

E-mail: atul.phy@gndu.ac.in Abstract Transition metal oxide thin films are of great scientific and technical importance with a variety of applications ranging from energy saving and energy storage devices to gas sensors. In the present study, V2O5, WO3, V2O5/WO3 and V2O5/WO3/V2O5/WO3 thin film samples were fabricated by reactive dc magnetron sputtering on Fluorinated Tin Oxide (FTO) substrates at 400oC. X-ray diffraction studies confirmed the formation of orthorhombic V2O5 and monoclinic WO3 films with (001) and (002) preferred orientation respectively. Raman studies supported the results obtained from XRD. UV-vis spectroscopy showed V2O5/WO3/V2O5/WO3 sample had the highest transmittance. The cyclic voltammetry (CV) studies were performed at three scan rates: 10 mV/s, 100 mV/s and 500 mV/s. The diffusion constant for H+ was calculated from CV data and showed a decrease with increase in the scan rate for all samples except for V2O5/WO3 sample. At each scan rate the diffusion constant was highest for V2O5/WO3/V2O5/WO3 and the values were 7.37×10-14 cm2s-1, 2.35×10-14 cm2s-1, 1.40×10-14 cm2s-1 for scan rates of 10 mVs-

1, 100 mVs-1 and 500 mVs-1 respectively. The highest value of interfacial capacitance (1165 mFcm-2) among all the samples was observed for V2O5/WO3/V2O5/WO3 at a scan rate of 10 mVs-1. This study suggests that V2O5/WO3/V2O5/WO3 sample has significantly improved electrochemical properties as compared to the individual films along with good optical transmittance.

Abstract In order to comprehend the stability of an organic molecule it is important to study the nature of its intermolecular interactions. To understand the nature of these interactions and their influence on the crystal packing it is important to calculate the energy associated with these interactions. The lattice energy of the compounds can be calculated by using PIXELC module in Coulomb-London-Pauli (CLP) package and can be separated into corresponding coulombic, polarization, dispersion and repulsion contributions. The lattice energy calculated using PIXEL reveals energetically more stable packing form. In this regard, we have identified from the literature a molecule 3-(Bromoacetyl) coumarin that exist in two different polymorphic forms and extracted molecular pairs from the crystal packing of both forms providing maximum stability to their respective crystal structure. It is found that the weak intermolecular interactions play an important role in the stabilization of the crystal packing of these polymorphs and one polymorphic form is energetically more stable than the other.

Preeti Verma1*, Kuldeep Singh2 and S. K. Khosa1 1Department of Physics and Astronomical Sciences, Central University of

Jammu, Samba, J&K– 181143, India 2Department of Physics, University of Jammu, Jammu

E-mail: preetiverma130587@gmail.com Abstract Doubly-odd nuclei are very interesting candidates for the nuclear structure studies as energy levels in such nuclei are most sensitive to variations of single-particle states. In general, these doubly-odd nuclei are difficult to study, both experimentally and theoretically, due to the complexity of their low-lying spectra. However, with the advent of recent experimental techniques and computational advances, it has now become feasible to explore the nuclear structure of doubly-odd nuclei. If we talk, in particular, about the A~ 70-80 mass region, stimulating new data have been accumulated, in recent years, on the odd-odd nuclei in this region of nuclear chart around fpg-shell. In order to gain a better understanding of the structure of doubly-odd nuclei lying in this mass region, the theoretical framework of Projected Shell Model (PSM) has been applied and the nuclear-structure properties like yrast spectra, reduced transition probabilities, etc. have been studied for some nuclei. The emphasis is laid on studying the phenomena of Signature-splitting and Signature–inversion which are the characteristics of this mass region. The present calculations reproduce reasonably well the available experimental data on the yrast bands and also predict the new high spin states, where current data are still sparse. While the phenomena of Signature-splitting and Signature–inversion have also been studied in detail within the context of Projected Shell Model, the transition probabilities, B(M1)’s and B(E2)’s are also reported for the first time for most of the transitions.

- 144411, Punjab, India Department of Applied Sciences, DAV Institute of Engineering and

Technology, Jalandhar, 144008, India Abstract In this paper, we develop an analytical formalism for THz generation from laser filaments in the presence of static electric field in a magnetized collisional plasma. Two femtosecond laser pulses with different frequencies undergo filamentation in magnetized collisional plasma to have non-linear coupling in the presence of transverse static electric field. This results in balancing action of static ponderomotive force with pressure gradient force and forms transverse density ripple and non-linear ponderomotive force couple with density ripple to provide strong non-linear transverse current which results in excitation of THz radiations at resonance. This coupling is further enhanced by electric static field. PHY08-Nonlinear dynamics of matter waves trapped in potential well with perfectly rigid walls

Moment theory in W.K.B approximation has been used with the goal to find semi analytical solution of Gross Pitaevskii equation that governs the evolution of the wave packet with time. A set of coupled equations governing the evolution of the size of wave packet along the three axes has been obtained. The two body and three bodies’ interactions between the atoms of the cloud have been modelled by cubic quintic nonlinearity. Numerical simulations have been carried out to see effect of cloud and trap parameters on the evolution of the size of cloud.

Abstract ZnS:Mn2+nanoparticles passivated by biocompatible layer biotin have been synthesized by chemical co-precipitation route. X-ray diffraction (XRD) results confirmed zinc blend structure with particles sizes ranging from 1.5 to 1.9 nm. The small particle sizes are believed to have due confinement of the particles in the biotin matrix. Scanning Electron Microscopy (SEM) analysis shows smooth and polygon shape potato like morphology having cluster size varying from 77µm to 182µm. Optical measurement shows the band gap of 3.85 eV which is blue shifted and is attributed to the quantum size effect. The particle size estimated for this gap is to be 2.03 nm and is in good agreement with sizes obtained from XRD. The luminescence feature of the as synthesized sample was also reported. The photoluminescence (PL) spectra shows two broad peaks centred at 410 nm and 520 nm respectively. The first emission at 410 nm attributed to the defect-related emission of ZnS with a short time while another peak at 520 nm attributed in the green region of the visible spectrum due to the elemental sulphur species on the surface of zinc sulphide. The both emissions are blue shifted and are attributed to the small particle sizes. The well known manganese related orange-red luminescence at 590 nm is not observed and is completely quenched that confirms that the Mn2+ ions are distributed outside the ZnS crystals. A new emission at 335 nm appears to have radiative transitions from the defect level to the acceptor levels. Thus, by using suitable activator and capping molecule, we are able to stabilize the growth of nanoparticles at room temperature, thereby enhance the structural and opto-electronic properties.

Abstract It is well known that the doped SnO2 thin films are widely used as H2S gas sensors. But the application of pure SnO2 thin films as sensors for different gases is not much explored area. In this paper an attempt has been made to prepare thin films of pure SnO2 with simple and cost-effective technique such as reactive thermal evaporation and use them for application as sensors for H2S gas. These thin films show marginal sensor signal for 5-150 ppm of H2S gas in the temperature range of 160 – 220 oC.

Abstract The densities and ultrasonic velocities of binary mixtures of triethylene glycol are measured at different temperatures and at frequency of 2 MHz over entire range of mole fraction. Various theoretical models such as Nomoto, Impedance, Junjie, Van Dael and Vangeel have been used to compute theoretical ultrasonic velocities. The average percentage error has been calculated and chi-square test for goodness of fit has also been to check the validity of theoretical models. The deviation from experimental results is interpreted in terms of molecular interactions among the components of the binary mixtures.

E-mail: kc.juglan@lpu.co.in Abstract The Density and Ultrasonic Velocity of Adrenaline with KOH have been measured at different range of temperatures for different concentrations. Ultrasonic velocity and density values increases with increase in concentration. By using ultrasonic and volumetric data various parameters such as adiabatic compressibility, acoustic impedance, available volume, molar volume, intermolecular free length, Rao’s constant, Wada’s constant, Van Der Waal Constant, relative intensity and effective molecular weight have been calculated. With rise in temperature the interaction between the solute and solvent particles increases, which is confirmed by available volume and intermolecular free length. The non-linear variations in Rao’s constant, Wada’s constant, Van Der Waal Constant and other parameters suggest the presence of complex formation or charge transfer interaction or dipole-dipole interaction or dispersive forces or maybe all in the solution.

Department of Physics, School of Chemical Engineering and Physical Sciences, Lovely Professional University

E-mail: deepak.23309@lpu.co.in Abstract Tin sulfide (SnS), being a binary metal chalcogenide, can be a potential absorber material for the thin film photovoltaics because of its optimum direct band gap (1.3 eV) and high absorption coefficient (104 cm-1). The constituents Sn and S are earth abundant and non-toxic elements which proposes SnS as a cost effective and eco-friendly absorber material for thin film solar cells. In the present work, the electrical and optical properties of SnS thin film solar cells have been optimized and analyzed by Solar Cell Capacitance Simulator (SCAPS). The effects of various layer parameters such as thickness, band gap, acceptor density, defect density, electronic band offset etc. on the IV-curve have been investigated to obtain better device performance. The maximum PV efficiency achieved by the PV device is 16.4% with VOC = 929 meV, JSC = 24.04 mAcm-2 and FF = 73%. The VOC value is higher than the reported values for kesterite CZTSSe absorber based solar cells. Consequently, the SnS can be a potential contender for the contemporary thin film solar cells.

Abstract Because of the availability of robust amount of the experimental data on variety of even-even, even-odd, odd-even and odd-odd nuclei in the nuclear chart, one of the main thrust in the nuclear structure physics is to reproduce the available experimental data for the nuclei from various sections of the nuclear chart, and to predict the unmeasured properties of nuclei for various deformed regions such as A ~ 60, 80, 100, 130 and many more, distributed all over the nuclear chart. One of the regions which have attracted the considerable attention of the nuclear physicists (both experimentalists and theoreticians) in the recent past is A ~ 130 mass region. Since nuclei lying in A = 130 mass region have interesting properties, their structures have been the subject of many studies. Therefore, with this incentive in mind, I have decided to study the Barium nucleus within the context of different frameworks of calculations and then made a comparative study to check the validity of the models. From the calculations, following conclusions have been drawn from the present study: 1. The intrinsic quasi-particle structure of yrast line has been analyzed. It has

been observed that yrast line is formed from various multi-quasi-particles. 2. The efficacy of applied models is checked by comparing the experimental

data with the theoretical results. The calculations reproduce very well the available experimental data.

Abstract Density, speed of sound and viscosity of ethane-1, 2-diol, methanol and methyl 4-hydroxybenzoate (methylparaben) at different concentrations and at constant temperature T=298K have been measured by Anton Paar DSA 5000 M density and sound velocity meter and Ostwald’s viscometer respectively. Experimentally measured values of density, speed of sound and viscosity are employed to calculate various acoustical parameters such as acoustic impedance, intermolecular free length, adiabatic compressibility, relaxation time, ultrasonic attenuation, relative strength, relative association and Gibb’s free energy. Graphs for each acoustical parameter against concentration are plotted with the help of Origin. The linear variation is found for most of the acoustic parameters which implies the absence of complex formation in ternary system studied.

Abstract The various acoustical parameters such as acoustic impedance, intermolecular free length, adiabatic compressibility, relaxation time, ultrasonic attenuation, relative association and Gibb’s free energy of polyethylene glycols with molecular weight 200 and 600 in aqueous sodium methyl para-hydroxybenzoate have been determined at 250C from the data of density, speed of sound and viscosity. Jone-Dole’s equation has been employed to analyze the experimental results of viscosity. The existence of interaction among the fragments of ternary liquid mixtures has been determined from viscosity coefficients. The polyethylene glycols act as the structure builder in water. The viscosity coefficient B surges with escalation in molecular mass of polyethylene glycols. The structure builder property of polyethylene glycols follows the order PEG-600 > PEG-200.

Abstract Electron acceleration due to plasma Wakefield generated by plane polarised laser field in the presence of pulsed magnetic field has been investigated. Laser propagation is considered in transverse direction to the plasma wave. The electron gets trapped in the plasma Wakefield and excited in the combined effect of plasma and laser fields. The pulsed magnetic field induces a resonant effect and contributes to additional gain in the electron energy. Laser, plasma and applied magnetic field parameters are optimized to achieve high energy gain.

Abstract Structural investigation of xLi2O-(100-x) TeO2 (x=20 and 25 mol %) glasses were carried out by density measurements, Differential Scanning Calorimetry, Raman spectroscopy, High energy synchrotron x-ray diffraction and neutron diffraction techniques. The glass short-range and medium-range structural properties were determined by Reverse Monte Carlo simulations of the diffraction datasets. Glass density decreases from 5.09 g cm-3 to 4.91 g cm-3, while the glass transition temperature also decreases from 265oC to 252oC with increase in Li2O concentration from 20 to 25 mol %. RMC analysis successfully found that the nearest neighbour distances of Te-O and O-O linkage are 1.85 Å and 2.76Årespectively. The Li-O peak is asymmetrical with maxima at 2.09Å and 2.15Å. The average co-ordination number of Te ions with neighboring oxygens decreases from 3.88 to 3.79due to the structural transformation: TeO4→ TeO3, a result which is consistent with the Raman findings. The coordination of Li+ with oxygen ions increases from 3.65 to 3.99 with an increase in Li2O mol %. The coordination number distributions revealed that glass network predominantly consists of TeO4, LiO4 and LiO3structural units with small amounts of penta and hexa co-ordinated units. The O-Te-O bond angle distribution has peaks in the range: 82.5° to 86.4°, similarly, the O-Li-O and O-O-O bond angle distribution has a peak at 80.4°and 58.7° respectively.

Abstract Steroids are the hormones that play a critical role in endocrine systems which control the regulation of metabolic processes. These hormones stimulate biological responses in a wide range of tissues to influence endocrine processes such as sexual differentiation, reproductive physiology, maintenance of salt balance and sugar metabolism. Synthetic derivatives of steroids have also attracted a good deal of attention for the purpose of developing drugs to treat hormone related disease. Pregnane being one of the saturated steroid hydrocarbons found to exist as α- and β-pregnane. The title compound, C36H46O5, is a steroidal derivative, the crystals of which were crystallised by using slow evaporation technique. It crystallizes in orthorhombic space group P212121 with the following unit-cell parameters: a= 6.0541(3), b= 22.0116(14), c= 23.1297(17) Å and Z = 4. The crystal structure was solved by direct methods using single-crystal X-ray diffraction data collected at room temperature and refined by full-matrix least-squares procedures to a final R-value of 0.0541 for 3425 observed reflections. In the crystal structure, two cyclohexane rings adopt chair conformations whereas cyclohexene and pentane rings exhibit half- chair conformations. The crystal structure is stabilized by C-H…O and C-H…π type of hydrogen interactions. The C-H...π interaction plays a crucial part in assembling the molecules into an organized supramolecular structure. The detailed results will be presented later. The chemical structure of the title compound is presented below.

Abstract The methanimine molecule is of great interest for astronomers and astrophysicists. It is considered as a prebiotic molecule as it is a potential precursor of Glycine, the simplest amino acid. The reaction of CH2NH with HCN in Interstellar medium makes aminoacetonitrile (NH2CH2CN) which further reacts with H2O to make glycine (NH2CH2COOH). The amino-acids like Glycine are building blocks of proteins which are essential for life to occur. Earlier, we have calculated the radiative life times and Einstein A-coefficients for transitions between 69 lowest rotational energy levels of methanimine. In the present study, we have obtained the anomalous absorption in 202 – 111 transition of methanimine at 33.705893 GHz. We have solved the statistical equilibrium equations coupled with the equations of radiative transfer. The brightness temperature is found to be minimum around the hydrogen molecular density of 104.5 cm–3 and it rises on both sides of this density.

Bhopal-462008, Madhya Pradesh State, India Abstract Heusler alloys have been promising materials for their ferromagnetic behavior, half-metallicity, high magnetic moment, large Curie temperature and thermo-electric performance etc. These properties allow them to be smart materials for possible applications in spintronic devices, memory devices and thermo-electric generators etc. Heusler alloys delineate ferromagnetic behavior even though these are formed of diamagnetic or paramagnetic elements. The Mn2CoCr, full Heusler alloy has been investigated with respect to its electronic structure, magnetic moments, and thermoelectric properties for the first time using density functional theory (DFT) based full potential linearized augmented plane wave (FP-LAPW) method. The estimation of total energy confers F-m3m structure, which is according to the available experimental data. We have estimated results using GGA and GGA+U approximations to elucidate accuracy in the results. The estimated total magnetic moment is found to be 4.87 and 5.02 µB by GGA and GGA+U, respectively. Further, we have calculated Sibek co-efficient and power factor. The present calculations open scope for the experimentalists. PHY24-Electron acceleration by surface plasma wave on metallic grating

Kanwal Gurbakhsish Kaur, Niti Kant, Jyoti Rajput Department of Physics, Lovely Professional University, Punjab, India

Abstract The electron acceleration with the field of surface plasma waves created in the interaction between a femto second laser and a metal sheet of finite thickness. The amplitude of surface plasma wave is maximum at the interface of two media and starts decays exponentially as we move away from the interface. With the help of a glass prism we can excite this mode by the use of a femto second laser. The applied magnetic field (along y-axis) bends the trajectory of electron and helps the electron to gain energy by resonance and as a result, the electron gets accelerated.

Abstract The structure of xSrO-(100-x)TeO2 glasses (x = 5 and 10 mol%) and SrTeO3 crystalline samples was studied by synchrotron high energy X-ray diffraction (HEXRD), Reverse Monte Carlo (RMC) simulations and pair distribution function analysis. The short-range structural properties of glasses such as Te-O bond-length, Te-O speciation, and O-Te-O, Te-O-Te bond angle distributions were determined by RMC simulations. The Te-O co-ordination number (NTe-O) for 5SrO-95TeO2 glass sample is 4.01 which decreases to 3.94 on increasing the SrO concentration to 10 mol%. The changes in NTe-O revealed that the glass network predominantly contains TeO4 units with a little amount of TeO3 units. The atomic pair correlation distribution shows the first peak at 1.91 Å due to the Te-O bonds; this peak is found to be highly asymmetrical due to the wide range of Te-O bond lengths. The O-Te-O bond angle distributions show maxima at 79° and confirm that the Oaxial-Te-Oequitorial bonds are the most abundant linkages in the tellurite network. The glass samples were annealed at 450°C for 4 hours and crystallized into the monoclinic SrTeO3 phase. The unit cell parameters of the SrTeO3 phase were refined by Fullprof Rietveld suite and were found to be: a = 28.15 ± 0.01 Å, b = 5.92 ± 0.01Å, c = 28.65 ± 0.01 Å, α =γ= 90° and β = 114.36 ± 0.06°. The atomic pair correlation distribution of monoclinic SrTeO3 phase shows the first peak at 1.88 Å due to Te-O correlations and is same as in the glassy phase.

Abstract The oxides of Zr, Hf, and their silicates are used in microelectronics devices and HfSiON (κ=14) is the currently used gate-oxide in logic devices. However, in near future, oxides having high dielectric constant (high-κ) >25, good thermodynamic stability (upto 1000 K), large conduction/valence offset with Si (above 1 eV), and large band gap (above 5 eV)are needed in the semiconductor industry for the sub-nanometer technology node as per the Moore’s law[1][2]. Hence, the aim of the present work is to find the high-k oxide that is compatible with CMOS process. To this effect ceramicHf0.2Zr0.6 Dy0.1Ta0.1O2 (HZDTO) has been synthesized using solid-state reaction route and various properties are examined. Single-phase material was realized at 1600oC of sintering for 8 hr as revealed by X-Ray Diffraction analysis. The targeted composition analysis can be revealed with Energy-Dispersive X-ray (EDX). From the electrical measurements, it is found that HZDTO is having 29, and 0.04, dielectric constant and loss tangent respectively at 100kHz. The I-V characteristics showed low leakage current, ~5 x 10-10 A/cm2 at 7kV/cm, and unvarying capacitance-voltage characteristics. In short,characteristicsof the bulk HZDTO aresuitable for gate-oxide applications in future logic devices and technology.

Abstract Calcium tungstate (CaWO4) nanoparticles were prepared by co-precipitation method and doped with dysprosium oxide (Dy2O3) by solid-state method followed by sintering at 800oC for 6h. Synchrotron X-ray diffraction studies were performed on 2 samples: CaWO4(Sample Code: CW) and 10-mol% Dy2O3 doped CaWO4 (Sample code: CWDy10) on angle dispersive X-ray diffraction (ADXRD) beamline BL-12 on Indus-2 synchrotron source. The crystal structure of CW is found to be tetragonal whereas in CWDy10, few small peaks due to cubic Dy2O3 are also observed along with the tetragonal phase of CaWO4. The structural parameters were obtained by Rietveld refinement of ADXRD data using FullProf software, which shows that the lattice parameters increase from a=b=5.237±0.001Å, c=11.361±0.001Å in CW sample to a=b=5.242±0.001Å, c=11.369±0.001Å in CWDy10. The short-range structure of CaWO4 consists of CaO8 and WO4 units. All the W-O bonds in WO4 have the same bond length with the value 1.77±0.01 Å in sample CW which increases to 1.80±0.03 Å in CWDy10. CaO8 units are found to have two types of Ca-O bond lengths: 2.43±0.01 Å and 2.46±0.01 Å which increase to 2.45±0.01 Å and 2.48±0.03 Å on adding 10% Dy-doped sample. Raman spectra of all the samples show W-O vibrational modes. Photoluminescence spectroscopy reveals that Dy-doped samples show intense peaks at 575 nm due to the emission of yellowish light, with maximum luminescence at 1 mol% doping followed by continuous decrease, exhibiting concentration quenching phenomenon.

E-mail: amukam@gmail.com Abstract Near Infrared Spectroscopy is an effective technique for detecting the presence of sugar as an adulterant in milk in the present work. A chemometric model was formulated to evaluate the presence of sugar in milk, qualitatively as well as quantitatively using NIR Spectroscopy. Total 24 samples were prepared using three different varieties of milk, out of which three samples were pure and rest were having sugar present in them. Those 21 milk samples were adulterated with sugar at seven different levels: 0.2%, 0.4%, 0.6%, 0.8%, 1.6%, 3.2%, 0.8% and 6.4% of sugar respectively for each kind of milk. The data collected from NIRS instrument was analyzed using chemometric software (CAMO Unscrambler version X 10.3). The Principal Component Analysis (PCA) was run on the sample set to know the relation between the different samples on the basis of the Near Infrared spectral data. It was observed that the PCA score plot could classify the samples in three different groups on the basis of their adulteration: low, medium and high adulteration. Partial least square (PLS) regression analysis was used to develop a statistical model to predict the percentage of sugar in the adulterated milk samples by selecting vital wavelengths. It was noticed that the regression model revealed quite good results for the prediction of sugar adulterated milk samples with coefficient of correlation higher than 0.9 and the root means square error of validation (RMSEV) was 0.04. Thus, it was concluded that NIR spectroscopy could provide dairy industry a simple, efficient, quick, green and non-destructive technique for detection and quantification of milk adulteration.

Abstract The glass samples having the composition: xM2O3-(25-x)Li2O-75B2O3 where x=0,1 and M=Eu, Dy and Er were synthesized by melt quenching method. The samples were characterized by density measurement, Differential Scanning Calorimetry (DSC), UV-visible, Raman and photoluminescence spectroscopy. Density of rare earth doped lithium borate glasses was higher than that of pure lithium borate glass sample and it lies in the range of 2.20 to 2.33 g cm-3. The thermal parameters including glass transition temperature (Tg), crystallization temperature (Tc) and melting temperature (Tm) were determined from DSC. It was observed that the Tg increases from 511℃ to 516℃on doping with rare-earth ions. The short-range structural properties of glasses were determined by Raman spectroscopy and optical absorption spectra of all the glasses were recorded in the wavelength range 200-1100nm. For luminescent properties, theEu3+ doped glass sample were excited at 395 nm, Dy3+ doped sample at 360 nm and Er3+ doped samples were excited at the wavelength of 380 nm. The emission spectra revealed that Eu3+ doped samples show emission lines: 5D0→7F0(576nm),7F1(590nm), 7F2(614nm) and 7F3(650nm), Dy3+show emission transitions: 4F9/2→6H15/2 (481nm) and 6H13/2 (574nm) while Er3+doped samples exhibit 2H9/2→5I15/2(417nm), 2H11/2→4I15/2 (517nm) and 4F5/2→4I13/2 (623nm) emission lines.

Punjab, India E-mail: Jatinderkhaira07@yahoo.com

Abstract Bismuth exhibits interesting magneto-transport behaviour both in bulk and thin film form. Oblique angle deposition is powerful technique that can be used to tailor the physical properties of the films because it causes significant modification of grain growth and morphology. In the present work, bismuth thin films were deposited on glass substrates by varying the deposition angles (inclination of substrate surface with the horizontal direction) by thermal evaporation. Crystalline bismuth films with hexagonal crystal structure and (003) preferred orientation were grown. Scanning electron microscopy studies show significant changes in topography with the deposition angle. Crystallite size of the Bi films decreases from 48 nm to 23 nm while the value of surface roughness decreases from 35 m to 8 nm with the increase in the deposition angle from 0o to 75o. Magneto-resistance studies were performed on thin film samples at 300 K and 1.5 K up to maximum magnetic field of 8 T and it was found that the samples deposited at oblique angle deposition show significantly smaller values of magneto-resistance.

Abstract The very precious resource of Earth, the groundwater is being contaminated and polluted day by day. E-Waste is one of the major cause for this problem related to ground water. E-wastes are produced mainly due to discarded electronic gadgets like PCs, tablets, hard drives, printers, monitors, batteries, mobile phones, television, etc. The use of these electronic gadgets is increasing enormously day by day around the globe. Lack of awareness about the proper disposal of these e-wastes cause serious health and environmental issue in developing countries like India and to some extent in developed countries. Discarded computers, mobile phones and other electronic equipment that are considered as e –waste contain hazardous toxic metals like chromium, lead, mercury, iron, zinc, copper, cadmium etc. These e –wastes are dumped in the landfills near the industries where large area of land is available. As most of the industries are located near the water sources, the toxic e-wastes are percolated inside the water hence make the water contaminated inside the deep aquifers. This water is not safe for drinking and other purposes. The quantity of pollutants is more near to the landfill sites and reduces as the distance between the landfill site and aquifer increases. In the present work, a literature survey of groundwater pollution by e-waste and its remedial measure to reduce groundwater contamination is being done.

Abstract In recent years, a large amount of work has been done over the last few decades on the rare-earth nuclei around the mass 160. Moreover, nuclear deformations of Gd isotopes show a gradual transition from a spherical shape near the closed shell to a prolate deformation in neutron-rich region. Much of the interest lies in the fact that these nuclei dwell within a highly transitional area of deformed space and thus can provide a fertile ground to investigate quasiparticle structures, alignments and some other properties. Thus, in the present work triaxial projected shell model (TPSM) has been employed to describe bands. This model uses the shell model diagonalization approach and it is similar to the conventional shell model approach except that the basis states in the TPSM are triaxially deformed rather than spherical. As an application of the triaxial projected shell model, a systematic study of the high-spin states in 156,158Gd isotopes is performed. The calculated yrast and bands are compared with the known experimental data, and it is shown that the agreement between theory and experiment is quite satisfactory. PHY35-Study of vibrational bands of even-even 176,178Hf nuclei

Ridham Bakshi*1, Surbhi Gupta1, Suram Singh2, and Arun Bharti*1 1University of Jammu, Jammu-180006

2Central University of Jammu, Jammu-181143 Abstract The strong coupling of quasiparticle excitations with γ vibration is shown to occur in transitional nuclei. In the present work, high-spin band structures in 176,178Hf are studied by using multi-quasiparticle Triaxial projected shell model approach. The systematic yrast level, Vibrational bands deformation systematic of these nuclei are calculated and compared with the available experimental values. The potential energy surface calculations suggest that 176,178Hf have significant softness to axially asymmetric shapes, which can strongly modify the level distribution. The Phenomena of back-bending in moment of inertia and staggering in Vibrational bands have also been studied for these nuclei and the present TPSM calculations and have been found to be in good agreement with the available experimental data.

PHY36-Systematic analysis of band structure of 51Cr

Simi Gupta1*, Surbhi Gupta1, Suram Singh2and Arun Bharti1 1University of Jammu, Jammu-180006

2Central University of Jammu, Jammu-181143 Abstract The fp-shell nuclei far from the valley of stability are of particular interest in recent experimental and theoretical studies. A large degree of experimental and theoretical effort has been directed towards characterizing and understanding the changes in shell structure which take place when moving away from the line of stability. Various studies have shown the magic numbers themselves to be remarkably fragile, appearing and disappearing over relatively small regions of the nuclear chart. To explore the structure of fp-shell nuclei bounded by N = 28–40 and Z = 20–28, is one of the most exciting challenges in low energy nuclear physics today. Hence, in that direction, we have selected 51Cr isotope for the present study and a systematic study of the high spin states of yrast-band for the odd mass 51Cr isotope is carried out by using Projected Shell Model approach. The back-bending in moment of inertia and yrast spectra has also been calculated and compared with the available experimental data and have been found to be in good agreement.

Abstract Various relaxation processes in the supercooled state of D-xylose have been investigated using dielectric spectroscopy over a wide frequency (1mHz – 1MHz) and temperature range (120-350 K). The main relaxation process (α) which is responsible for the glass transition phenomena, another secondary relaxation process is clearly visible below the glass transition temperature. This process is probably due to the rotation of hydroxymethyl (-CH2OH) side group attached to the sugar ring. In addition, we have applied Coupling model to find the location of intermolecular relaxation below the glass transition temperature (Tg). The temperature dependence of various dielectric parameters viz. τα, τcm, τγ and τσ have been critically examined. The current experimental result shows that, log10σdc vs. log10 τα dependence is nonlinear and hence can be described with the fractional Stokes-Einstein-Debye relation.

E-mail: suman.rani@lpu.co.in Abstract Terbium aluminium garnet (TAG) with broad transmission range (350–1500 nm), high physical and chemical stability is one of few hosts which are being investigated for the realization of photonic devices by doping rare earth elements in it; rare earth elements are interesting because of their emission in the visible region. One of the interesting rare earth elements is gadolinium (Gd) with 4f7 configuration, 8S7/2 ground state and first excited state at 32000cm-1; the inherent presence of such a first excited state eliminates the possibility of infrared emission which invariably reduces the efficiency of any visible light emitter. This study reports the emission (400-700nm) properties of Gd (0.1, 0.5, 1.0 mol%) doped TAG nanophosphor synthesized by sol gel technique. The emission was excited with 280, 380 and 460nm radiation from a Xe lamp. When excited with 280nm radiation the overall emission intensity enhanced on Gd doping, the amount of enhancement increased with the increase in doping concentration implying the possibility of energy exchange from the dopant Gd to Tb in TAG lattice. On the other hand, with 460nm excitation emission quenching was observed with Gd doping which could be due to non-radiative emission resulting from Gd doping. The excitation with 380nm resulted in emission at 431nm in undoped TAG which was quenched with Gd doping, However, prominent emission peaks at 484, 513,570 and 683nm were observed in TAG doped with 1.0mol% Gd. This emission could be due to 6Pj to 8Sjtransition of Gd. This paper reports the detailed mechanism responsible for the emission observed with the three excitations.

PHY43-Electron acceleration by Cosh-Gaussian laser beam in the presence of axial magnetic field

Jitender Singh, Niti Kant * Department of Physics, Lovely Professional University, G.T. Road, Phagwara

(144411), Punjab, India. Abstract This paper presents a scheme of electron acceleration by cosh-Gaussian laser beam (CGLB) in the presence of axial magnetic field. CGLB possesses higher power and has ability to focus earlier than the Gaussian beam. Nonlinear differential equations have been set up for the beam width and intensity of CGLB. By using different values for decentered parameter ‘b’ and the intensity parameter ‘ao’ of CGLB the electron energy gain with propagation distance has been plotted graphically. It is observed that the presence of axial magnetic field along the direction of laser beam propagation significantly affects the electron energy.

PHY44-Significance of edge doping and varying length of pristine and doped graphene sheets on its electronic properties

Preetika Sharma1* and Gaurav Sapra1 1UIET, Panjab University, Chandigarh

E-mail: sapracts@gmail.com Abstract The effect of edge doping and increasing the length of graphene sheet is studied by density functional theory. The doping in graphene sheet is done not only at surface but also at the edges. Edge doping not only alters the electronic properties but also increases the conductivity. In addition, the different lengths taken are with number of carbon atoms as 8, 16, 32 and 48. The band gap is a key property of electronic materials and the size of the gap is decisive for the suitability of a material for electronic devices. Thus, change in band structure, density of states and cohesive energy calculations are done. The calculations indicate the effect in the properties justifying the 48 carbon atom structure to be the most stable. The transconductance is directly proportional to the number of modes contributing to conduction and therefore high conductance can be seen in sheet with more number of carbon atoms. The variation of effective mass is also studies. As band gap opening decreases effective mass, the doped sheet is found to have less effective mass. However, the edge doping yields greater benefits as compared to surface doping which can be important for many future applications.

Abstract Compound (C11H12N4S2 ) crystallizes into triclinic space group P1 having unit cell parameters a= 7.7873 (2), b= 9.5982 (2), c= 9.6041 (2) Å, α= 76.608 (2), β= 70.602 (2), γ= 68.570 (2)°, Z=2. The number of observed reflections and the final reliability index (R-factor) is 2121, 0.032. Besides the routine structural description, the most interesting feature of structure elucidation is the existence of intramolecular C-H…S hydrogen bond which generates a S(6) graph-set. In addition to this the crystal structure is dictated by N-H…S intermolecular hydrogen bonds forming inverted dimers with 𝑅2

2(8) graph-set motif. Further stabilization of crystal packing is due to the presence of π-πstacking interactions between the phenyl rings.

PHY46-Third harmonic generation of Hermite Cosh Gaussian laser beam

Vinay Sharma, Vishal Thakur and Niti Kant* Department of Physics, Lovely Professional University, G.T. Road, Phagwara

-144411, Punjab, India. Abstract In present study we have investigated the third harmonic generation (THG) of self focused Hermite cosh Gaussian (HchG) laser beam, propagating through plasma. When intense short pulse laser propagates through plasma, it exerts ponderomotive force on electrons due to which electrons move away from the axial region, creating a low density plasma region. Due to electrostatic force, electrons gain oscillatory velocity and results density perturbation. Density oscillations at frequency 21 couple with oscillatory velocity of electrons, at the fundamental frequency of incident laser result THG. Due to phase mismatch with the incident pulse, the intensity of third harmonic pulse is smaller. Wiggler field satisfy the phase matching condition and this result enhancement of the normalized amplitude of third harmonic pulse. Using paraxial approximation, we derived the coupled differential equation for the normalized amplitude, of third harmonic pulse. Variation of normalized amplitude of third harmonic pulse with linear propagation distance is studied at different values of normalized intensity of fundamental laser, normalized wiggler magnetic and normalized plasma frequency. Key words: - Third harmonic generation, Hermite cosh Gaussian laser beam, relativistic self-focusing, plasma density, wiggler field.

Abstract Comprehensive quality assurance (QA) and beam data acquisition for commissioning of modern day medical linear accelerator (linac) used for cancer treatment in radiotherapy has been performed. Mechanical, electrical and radiological tests were performed to check linac performance as per American Association of Physicists in Medicine (AAPM) Task Group (TG) 142. The geometric isocentre accuracy, congruence check and calibration were performed using the IsoCal QA device. The radiation beam profiles, depth dose data and output factors for 6 MV SRS beam for the field sizes ranging from 2 × 2 cm2 to 15 × 15 cm2 were measured using SFD diode detector and cc13 semiflex ion chamber. The Multileaf Collimator (MLC) characterization in the Treatment Planning System (TPS) is done using the parameters measured with the cc13 semiflex ionisation chamber in water phantom. Dose measured with 2D ion chamber array was compared to that calculated in TPS. The MV and kV imager isocentre was calibrated to be coincident within ±0.5 mm with the radiation beam isocentre. The variation between SFD measured and ion chamber measured beam data is in good agreement for fields sizes down up to 2 × 2 cm2. Variation in output factors is ±0.56 ± 0.05 %. The measured beam data is imported and calculated in the Eclipse TPS and is found within 1% gamma agreement index (GAI) with the Analytical Anisotropic Algorithm (AAA) data. GAI for TPS verification QA is 97.8%, 98.5% and 98.3% respectively for jaw defined 2 × 2 cm2, 5 × 5 cm2 and MLC defined rapid arc SRS plan. Successful modelling of the photon beam for high dose rate SRS mode is achieved for clinical treatment of patients.

Abstract Fatty Liver Disease (FLD) is one of the most critical diseases that should be detected and cured at the earlier stage in order to decrease the mortality rate. In the recent years, many researchers have developed various Computer Aided Diagnosis (CAD) systems for the classification of fatty and normal liver ultrasound images. However, the performance of existing CAD systems is not good in terms of sensitivity in classifying the fatty liver images. Although a lot of work has been done in this area but still it is the subject of great significance due to increasing prevalence of fatty liver across the globe.In therapeutic imaging and diagnostic radiology, CAD has ended up a standout amongst the most important research topic. It introduces the pattern recognition software that analyse suspicious features on the image and help the radiologists to solve the problem. Over the past many years, prosperous research has been done on classifying liver ultrasound images. This paper presents the comprehensive survey of various Computer Aided Diagnosis systems for the classification of Liver Ultrasound images proposed and developed so far. In addition, paper analyses the previous researches conducted in related areas of CAD for liver Ultrasound, identifies the current state of art in the area and discusses current challenges and future directions to improve the diagnostic accuracy.

Abstract In this work, nano-composites of Graphene Oxide (GO) and Polypyrrolewith different proportionswere synthesized by chemical method. The variation in optical and structural properties in the composites have been studied and compared with the samples exposed to gamma radiations of dose 100KGy from a Co-60 gamma source. The FTIR peaks have been found to shift towards lower wavenumbers with the addition of graphene oxide and the shifts have been further enhanced with gamma irradiation. The band gap energy of polypropylene has been found to decrease with the addition of graphene oxide. The decrease in the band gap energies of the composites has been observed to decrease with gamma irradiation. The broader X-rays diffraction band of pure polypropylene has been changed to a sharp peak with the addition of GO to Polypyrrole. Some peaks have been found to diminish with gamma irradiation. The d-spacing has also been decreased with gamma exposure of the composites.

Abstract In the present study activity concentrations of terrestrial radionuclides226Ra, 232Th and 40K were measured by means of gamma spectrometry with NaI(TI) detector in soil samples collected from Pangi Valley, Himachal Pradesh, India. The activity concentration in soil samples ranged from 39.61 to 79.72 Bqkg-1 with average of 57.66 Bqkg-1for 226Ra, 32.8 to 66.57 Bqkg-1 with average of 49.69 Bqkg-1 for 232Th and 495.62 to 653.85 Bqkg-1 with average of 579.41 Bqkg-1 for 40K. Radium equivalent activity in all soil samples is found to be lower than the maximum permissible value 370 Bqkg-1, acceptable for the safe use. The average absorbed dose rate in air at 1 m height from the ground level in soil surface was found 81.43 nGyh-1, while corresponding average annual effective dose outdoor and indoor calculated to be 0.099 and 0.40 mSvy-1. The estimation of excess life time cancer risk assessments suggests about 13 out of 10000 persons may get affected by carcinogenic diseases due to indoor effective dose. The calculated external and internal hazard indices have been found to be less than unity. The average value of activity concentrations of radionuclides in soil samples from study area were compared with international values reported by United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR, 2000).

E-mail: srivastava_phy@yahoo.co.in Abstract Hexaferrites have for decades found to be of appreciable applications, such as in stealth technology, electronic devices and as absorbers of unwanted electromagnetic (EM) radiations. M-type strontium hexaferrites with chemical composition Ba1-xYxFe12-xCexO19 (x=0.0, 0.1, 0.2) have been synthesized via sol-gel method and calcinated at 950 0C. XRD patterns shows formation of M-type hexagonal ferrites without traces of α-Fe2O3.The presence of two prominent peaks between 400 cm-1 and 600 cm-1 in the spectra of FTIR gives the possibility of the emergence of M-type hexagonal ferrites. FESEM micrograph shows that the sample exhibits hexagonal plate-like grains. The dielectric properties were explained on the basis of Maxwell-Wagner model. The prepared sample with x=0.1 exhibits the highest dielectric constant (363) and low dielectric loss (0.089) was observed in the sample with x=0.0 at 100 Hz. Cole-Cole plot indicates that the dielectric properties of the prepared sample mostly come from grain boundary resistance (Rgb).

Sciences, Lovely Professional University 2Department of Physics, St. Joseph’s College Bangalore

E-mail: naveens222@rediffmail.com Abstract Self-phase modulation of a quadruple-Gaussian (Q.G) laser beam interacting with a periodic lattice of gold nano particles has been investigated. The self-phase modulation of the laser beam also known as Gouy phase shift occurs at a fundamental level from position-momentum uncertainty. Due to the nonlinear response of the free electrons of the gold nano particles, the laser beam gets self-focused, resulting in a transverse momentum spread of its photons. Due to this transverse momentum spread the longitudinal phase of the laser beam gets modulated. Following Euler Lagrange equations, a semi analytical solution of the Maxwell’s wave equation for the field of the laser beam has been obtained. Particularly the effect of dynamical variations of the beam width on longitudinal phase of the laser beam has been investigated in detail.

E-mail: srivastava_phy@yahoo.co.in Abstract Humidity and Temperature have dire influence on the both living and non-living organisms. They affect our day to day working system and hence sensors and sensing materials comes into existence. This paper investigates the effect of addition of polyaniline (PANI) on the properties of copper (II) oxide (CuO) nanoparticles. Sol-Gel method was used to synthesize CuO nanoparticles while PANI was obtained by oxidative polymerization process. The structural characterizations of the composite material and the effect of PANI on the CuO nanoparticles are studied through FESEM, XRD, FTIR and Raman Spectroscopy. XRD confirmed the formation of CuO without the presence of CuO2.FESEM showed the clear formation monoclinic structure of CuO. EDX revealed that Cu and O- atoms are in stoichiometry, thus confirming the formation of CuO bond and peaks of C, N and O are also obtained depicting the PANI formation. The characteristic peaks are obtained for both CuO (402.99-678.74 cm-1) and PANI (1109.94-1568.54 cm-1 and 3058.81-3436.21 cm-1) through FTIR. The Raman analysis of CuO sample showed 3 peaks (290.01 cm-1, 333.51 cm-1 and 624.81 cm-1) and while PANI showed peaks in the range from 1166.48 cm-1 – 1582.81 cm-1. The dielectric properties were investigated using Maxwell-Wagner model and Koop’s phenomenological theory. The fore-mentioned composite material can also be used as sensing material.

144411, Punjab, India Abstract In the present model, a detailed theoretical investigation of the nonlinear current density produced by beating of chirped pulse lasers in plasma having spatial ripple density is conducted. In our mechanism, we consider two Gaussian lasers with electric fields 1E and 2E propagating along z , polarized along y direction. The lasers have a linear frequency chirp and the frequency

1 and 2 can be chosen as the required frequency range. A transverse nonlinear ponderomotive force is experienced by the plasma electrons due to the lasers beating in plasma. As a consequence, plasma electrons get an oscillatory velocity that paired with the density ripple to generate a stronger transient transverse nonlinear current. Our theoretical simulation unveils that by optimizing the chirp parameter a prominent change in nonlinear oscillating current is depicted.

Abstract SnS1-xSex thin films prepared using multisource thermal evaporation from constituent materials taken in different weight percentages on annealing at 623K. The films are seen to possess polytypic SnS, SnS2, Sn2S3 phases along with binary SnSe and ternary SnSSe phases. The detailed study of phase variation from SnS to SnSe with changing selenium content in the film has been presented. The films without Se layer shows SnS dominated phase along with the presence of SnS2 and Sn2S3 peaks. However, the change in weight percentages by changing Se content in the films leads to the formation of ternary SnSSe along with the presence of polytypic SnS phase and finally transforms into SnSe phase. This transformation has been achieved with the increase in the Se content which leads to the dominance of SnSe phase with reduction in SnSSe. This transformation from SnS to SnSe exhibits a consistent increase in unit cell volume from 193.01 Å3 to 211.32 Å3 due to the insertion of higher atomic radii. Optical results exhibit direct and indirect bandgap with changed absorption coefficient. These changes in optical and structural parameters were corroborated with the EDAX and electrical analysis which showed different alloy formation with different selenium concentration.

Abstract NiCl2/ polyaniline composites with varying NiCl2 concentration have been synthesized and characterized for structural and optical modifications in polyaniline with the addition of NiCl2, and to study the influence on the electrical properties of polyaniline. FTIR spectral peaks attributed to various entities present in polyaniline have been shifted towards longer wavelengths with the addition of NiCl2. The d-spacing for the two x- ray diffraction peaks at 20.30° and 26.22° has been determined by using the Bragg’s relation and found to decrease with the addition of NiCl2. The SEM images of the composites indicate the uniform dispersal of the salt in the polymeric conformation. The band edge of UV-VIS spectra of the composites has been found to blue shift indicating increase in the band gaps with the increased NiCl2 concentration except for a concentration of 5%. The capacitance has been found to decrease with increase in frequency and the increase in the NiCl2 content. The resistance has been found to increase with the addition of NiCl2

thus establishing a positive correlation between the optical band gap and variations of resistance with the addition of NiCl2 to the polyaniline.

Abstract Radon monitoring has become a global phenomenon due to its health hazards. More than 55% radiation dose delivered to human kind on the globe from all natural sources is due to radon alone. Mostly Solid state nuclear track detectors in these paper LR-115 detectors are being used to obtain the time integrated concentration levels of radon/ thoron and their daughters. Of the total radon dose received by human population the indoor radon constitutes the maximum of 50% and rest from the environment, soil and water. Indoor measurements carried out by several laboratories all over the country show that the indoor radon levels vary from 1.5 to 2000 Bq m-3, while the normal level is in the range of 10 to 60 Bq m-3. It is rather difficult to compare the level in any part as the exposure conditions, the period of measurements and the calibration techniques used are not standardized. In this paper we have studied the indoor radon concentration in various localities of Chandigarh a union territory and capital town of Punjab, India. We also compared the result with all India radon concentration level and WHO/ UNSCEAR effective dose limit.

E-mail: jeeban.21059@lpu.co.in Abstract In recent years, solid state nuclear track detectors (SSNTD) have been used increasingly in variety of field ranging from archeology and geophysics to fission physics and space research. In nuclear physics their advantages lie in their small and flexible geometry, in their ability to withstand high temperature and in their being able to discriminate against high background of less ionizing radiations. When ionizing radiation falls on a solid state nuclear track detector, it produces minute trails of damage (perhaps 10-100 Ao in diameter) in a material whether by the thermal spike effect of more by ion explosion effect. We in this work irradiate CR-39 sample by ion beam of 93Nb with varied energy in the range 20 MeV to 1600 MeV. The damage trials produced were enlarged thousand times by subjecting the material to a suitable etching process (6N NaOH at 60o C Temperature). Then using continuous process of etching the maximum etchable track length was measured. Using well established SSNTD techniques the range and energy loss of the ion in polymer was calculated. The experimental result was then compared with theoretical data of SRIM and DEDXT programme. The theoretical data are in close agreement with our data.

Odisha-769008, India Abstract Solid electrolytes have attracted great interest recently in the energy storage system due to its potential to enable all solid-state lithium batteries. The energy density can be significantly enhanced by replacing liquid electrolyte with solid one. However, the ionic conductivity of solid electrolyte faces some challenges. To this effect, higher ionic conductivity (~10−3 S cm−1), very low electronic conductivity, wide potential window (up to 9 V), and good chemical stability of garnet type Li7La3Zr2O12 (LLZO) is of great interest. In the present work, single phase LLZO are prepared through acrylamide-based gel template method. Stoichiometric and compounds with excess Li (up to 40%) synthesized. The structural, microstructural and electrical properties have been studied using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and complex impedance spectroscopy, respectively. Rietveld refinement has been adopted to refine the XRD pattern of the compound to obtain the structural parameters. The complex impedance spectra have been recorded as a function of frequency at different temperatures. The electrical dc conductivity has been calculated form Nyquist plot. The temperature dependent dc conductivity has used to analyze the ionic conduction mechanism in the materials. In short, key issues and challenges in the preparation of LLZO and the aspects of ionic conduction, interfacial compatibility, and stability in air are discussed.

Abstract M-type hexaferrites have found considerable application in microwave absorption and magnetic recording. Sol-gel auto-combustion technique was utilized to prepare Ba0.7Dy0.3Fe11.4Cr0.6O19 nano-sized particles which were sintered at 1000 °C for 6 hours. XRD patterns of the prepared sample show magnetoplumbite phase of M-type hexaferrite along with the presence of hematite (α-Fe2O3) and polyaniline. Two specific bands in the range 400-600 cm-1 were observed in the FTIR spectra signifying the formation of hexaferrites structure. The peaks corresponding to polyaniline are also present in the FTIR spectra in the range 800-1600 cm-1. FESEM analysis shows grains with shape similar to hexagonal plate embedded on the surface of polyaniline. The band gap was found to decrease from 1.91 eV to 1.45 eV.

Abstract PVC/PANI composites radiated with 75KGy of Gamma radiations were studied for their modifications in optical and structural properties as compared to unradiated polymer composites. The study of FTIR spectra of gamma radiated and unradiated samples of polymer composite shows that the intensity of peaks decreases with gamma irradiation and at the same time shifts towards lower wave-number for pure PVC and its composites. It is further found that the water content has been reduced with Gamma irradiation and CO2 was released. The UV-VIS spectra for PVC/PANI composites were studied after irradiation with 75KGy of Gamma radiation and compared with unradiated composites. It was observed that the direct band gap, indirect band gap and urbach’s energy increases with gamma irradiation for pure PVC which may be attributed to increased cross linking in PVC due to irradiation. For other concentrations of PANI in composite the direct band gap, indirect band gap and urbach’s energy is found to decrease with irradiation. PL studies of composite showed that with the addition of PANI the colour of emission has been found to shift towards yellow. After irradiation the emission colour has been found to shift towards white colour whereas negligible effect has been found for composites with higher concentration of PANI.

Abstract Cashew nuts contain protein, fiber, nutritional, calcium and thus important healthy dose. Near infrared is nondestructive, fast, reliable, green technique and used for qualitative and quantitative analysis of food products. In this research work, Near Infrared spectra and chemometric analysis was used to build a statistical model for prediction of pentane content in cashew nuts. PCA result for pentane showed that the PC1 covers 79% and PC2 covers 11%. Most of the variability is found in the range 0.8-1 and low variability in the samples from range 0-0.2. Due to variability for the pentane content in given samples PLs model was developed for the same. PLS loading showed the important wavelengths for prediction of pentane content (700-1100, 1650-1730, and 2000-2060, 2100-2130). PLS result showed that pentane content can be predicted for cashew nuts with coefficient of correlation of 0.87 for calibration and 0.70 for validation and root mean squares error of calibration is 0.207 and for validation is 0.347. The results showed that NIR is nondestructive, fast, reliable, green technique for prediction of pentane content in cashew nuts in the range of 700-2500nm.

Abstract Rare earth nanophosphates find their place in wide variety of applications such as optical materials including lasers, phosphors and more recently as anti-UV materials. Pure and mixed Rare earth nanophosphates synthesized by wet chemical co-precipitation technique. Powder X – ray diffraction (PXRD) analysis revealed single phase formation with monazite phase structure with the increase in unit cell parameter and the X – ray density decreases with the mixing of two rare earth ion and is consistent with the difference in ionic radii and atomic radii of Ce3+ and Nd3+. Transmission electron microscope (TEM) studies revealed spherical morphology as well as rectangular platelet, like nanorods. Electrical properties viz., dielectric constant (ε/), dielectric loss (tan δ), a.c conductivity (σa.c) were studied as a function of temperature and applied frequency. The gradual decrease in dielectric constant with frequency indicates that the material may be having different types of polarization which can be explained on the basis of Maxwell – Wagner model. The influence of conductivity has been explained by considering the mobility of charge carriers responsible for hopping. The value of activation energy decreases with increase in frequency, suggesting conduction mechanism is due to hopping of the charge carriers from one site to another. The detailed results will be presented and discussed.

Abstract Electron acceleration by an Inverse Free Electron Laser (IFEL) pulse in the presence of static magnetic field has been studied. With high intensity laser and plasma interaction, plasma wakefield can be excited which can be further utilized to accelerate injected electrons. Highly energetic laser interacting with plasma excites a wakefield in which injected relativistic electrons are trapped. The presence of static magnetic field provides the additional resonance to the trapped electrons, and the energy of laser is transferred to electrons effectively thereby, resulting in highly energetic electrons of higher energy gain.

Department of Physics, Lovely Professional University, G.T. Road, Phagwara 144411, Punjab, India

E-mail: niti.kant@lpu.co.in Abstract Second harmonic generation of a relativistic self-focusing chirped pulse laser in plasma in the presence of an azimuthal magnetic field has been investigated. Ponderomotive forces are generated by the laser beam exciting electrons in an anharmonic potential in the plasma and the interaction of the electrons with the azimuthal magnetic field. The two effects combine to give us an improvement in second harmonic generation. If we increase the positive chirp parameter of the laser then a significant increase in the intensity of second harmonic radiation is seen and it is found that with the increase in the azimuthal magnetic field, the rate of production of second harmonic radiation increases.

E-mail: kanwarjitsingh@yahoo.com Abstract The alarming increased rate of bone disorder, osteoporosis and bone traumas grabbed the worldwide attention towards the bone regeneration abilities of bioceramics. Bioceramics implants easily get degraded at rate to match the new bone formation as they are highly biodegradable and biocompatible. The doping with the different metal ions such as Mn and Cr enhances biological efficacy of the bioceramics. Mn plays vital role in collagen formation, induces osteoblast cell adhesion and bone remodelling whereas Cr prevent bone related disorders, osteoporosis and metabolize glucose level in the body. In the presented work, the bioceramics composition of xCr2O3.(42-x)CaO.41SiO2.9P2O5-8MnO (where x=2and 8 mol%)were prepared by the sol gel process. Structure and surface morphology have been determined by XRD, FTIR and SEM which showed the significant apatite growth after soaking in simulated body fluid (SBF) for 1,3 and 7days. Degradation rate in SBF has also been investigated. The surface charge of prepared samples which is negative when immersed in simulated body fluid determined has been determined by zeta potential studies. The cellular behaviour has been evaluated by using human osteosarcoma MG63 cell line. The synthesized bioceramic compositions show potential for bone regeneration applications as implant material.

Phagwara, Punjab 144411 India Abstract The purpose of this study was to investigate the morphology of multiwall carbon nanotubes (MWCNTs) produced by thermal chemical vapor deposition (CVD) technique using field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) which revealed various other forms of carbon such as carbon nanofibers, nanofilaments, nanoladders etc. in addition to MWCNTs. Tip growth mechanism of CNTs was found operating in this study. The dependence of produced CNTs as a function of growth temperature and time was studied which showed that the CNTs growth take place in a specific temperature window only; yield being maximum at 700 C while the growth time showed that yield was saturated after one hour. This is in accordance with the mechanism of catalyst poisoning in which the catalyst becomes inactive due to deposition of carbon layer around it.

Abstract Proper shielding from harmful ionizing radiations is a mandatory requirement in nuclear facilities owing to the harmful effects on radiation workers and general public in case of radiation exposure. The present work is aimed at the investigation of the shielding properties of the prepared glass system of chemical composition (83.5+x)Bi2O3.(0.6+x)Li2O.0.1MnO2.(15.8-2x)B2O3 (with x = 0, 0.7 and 1.4 wt.% coded as L5, L10 and L15 respectively), with respect to the Gamma-ray, Beta and fast neutron radiation. The Gamma-ray shielding property of the glass system was also compared with the most commonly used Barite concrete and commercially available shielding glass ‘RS 253 G18’. Also, the neutron shielding properties was compared with common neutron shielding materials including Graphite, Boron Carbide and Polyethylene grains. An attempt was made in this study to select a better shielding material than the compared standard shielding materials. It is inferred that L15 glass sample is the best shield material for Gamma-rays, fast neutrons and also, for Beta radiation in the high energy region due to Bremsstrahlung, while in low energy region glass, L5 is better for Beta shielding.

Abstract Optical and structural characterizations of the Cu-doped and pure SnO2 thin films were done as a part of these investigations. In this respect, the effects of changing the concentration of the precursors on the thin film properties were investigated. SnO2 thin films both in pure and doped form were prepared by a sol gel spin coating technique. The metallic oxide (SnO2) films deposited were characterized using the UV Spectrophotometer and XRD studies. The average band gap for tin oxide thin films was found to be approximately 3.80eV. As for as direct band gap is concerned that the Cu doping appears to have no effect on the direct band gap which is in accordance with as reported in the literature. The indirect band gap for thin films was found to be approximately 3.48eV, 3.32eV and 3.20eV for different concentrations of the solutions respectively. The indirect energy gap of the Cu doped thin films decreases as 3.76 eV, 3.73 eV and 3.16eV respectively for different concentrations of the precursor solutions. The less value may be due to the addition of Cu- dopant and also may be due to growth of grain and improvement of the degree of crystallization.

E-mail: amanjotk251@gmail.com, paramjit.phy@gndu.ac.in Abstract The present work aims at studying the effect of hyperfine levels on sub-wavelength atom localization in five-level X-type atomic scheme. For closer match of numerical and experimental data, inculcation of nearby hyperfine levels is necessary. Since, the interaction of atom with standing wave fields is position dependent, henceforth the probe absorption profile encompasses the complete information about atom’s precise position. The density matrix approach is employed to show that by suitably adjusting the system parameters, hyperfine levels significantly alter atom localization pattern.

E-mail: parminderkaur9384@gmail.com Abstract In medical applications, where polymers and plastics are used as tissue equivalent and phantom materials, the determination of accurate values of radiation shielding parameters becomes very important. In this context, the present work is aimed at determining the values of radiation shielding parameters of two polymers, polyethersulphone (PES) and polyvinylidenechloride (PVDC) and then doing a comparative analysis of their shielding abilities in order to find a better material for shielding. The neutron shielding parameter was determined and was also compared with some common neutron shielding materials such as Boric Acid, Boron Carbide and Graphite. Furthermore, the shielding against charged particles i.e. neutron, proton and alpha particle was also studied with the help of the parameters, ‘mass stopping power’ and ‘projected range’. It was speculated that PES is superior to PVDC for shielding against neutrons, protons, alpha and beta radiation due to higher content of low atomic number elements per monomer unit. So, PES can be used potentially for radiation shielding in medical field.

Abstract In this work, spherical silica nanoparticles (SNPs) were doped into a ferroelectric liquid crystal (FLC). Dielectric relaxation spectroscopy was carried out in the range 20Hz-1MHz.Temperature and frequency-dependent dielectric permittivity were investigated in the undoped and doped system. It was observed that adding a small amount of SNPs, the permittivity increases ~20% than pure FLC mixture. A Goldstone mode of relaxation was observed both in pristine and SNPs doped FLC. The relaxation frequency of this mode was observed at ~570Hz and ~715Hz for pure and doped mixture respectively at 34oC. A single relaxation behaviour was also described in the form of Cole-Cole plot.

PHY89-Real-buy LPG detector: a microcontroller based gas leakage detection system for home safety

Engineering, Lovely Professional University E-mail: simrandeepkaurwazir@gmail.com

Abstract Liquefied Petroleum Gas (L.P.G) is highly inflammable and can burn even at some distance from the source of leakage. L.P.G is a mixture of hydrocarbon gases, the two most common being butane (C4H10) and propane (C3H8). Under moderate pressure, or in cooler conditions, it transforms into a liquid state. The pressure at which LPG becomes liquid, called its vapour pressure, likewise varies depending on composition and temperature; for example, it is approximately 220 kilopascals (32 psi) for pure butane at 20 °C (68 °F), and approximately 2,200 kilopascals (320 psi) for pure propane at 55 °C (131 °F). The specific calorific value of LPG is 46.1 MJ/kg. Liquefied Gas is heavier than air, & can lead to LPG-‘lakes’. So it is common to add a foul smelling odorant to the gas in order to reduce the risk of explosions [1]. Most of the fire accidents occur because of inefficiency in the detection of L.P.G. So, “Real-Buy LPG Detector” is a project which has characteristic that makes the detection of L.P.G economical and convenient. In this project gas leakage is identified by using sensors which works only in closed environment. This paper deals in the detecting and controlling of the LPG leakage. This circuit detects its presence by alarming a buzzer, or glowing a LED as an indicator, turns off the electricity of the entire house, and simultaneously turn on the kitchen’s exhaust in order to dissipate the leaked gas. Implementing this application can be useful for homes, companies, power and gas plants, which can save many lives of people.

PHY90-Weibel instability of a relativistic electron beam in a plasma channel

Ram Jeet, Sanjay Babu and Asheel Kumar* Department of Physics, University of Allahabad, Prayagraj-211002

Email: rjpatel896@gmail.com, asheel2002yahoo.co.in Abstract A nonlocal theory of Weibel instability of a relativistic electron beam, propagating through a plasma channel, is developed in the slab geometry. For beam density greater than the plasma density ( 00 nn b ), the beam of finite spot size pushes the plasma electrons out of the beam region and imparts return velocity to plasma electrons in the outer region. The relative drift between the inner region beam electrons and outer region plasma electrons drives the electromagnetic perturbation with transverse scale length comparable to the spot size of the beam. The growth rate increases with the parallel wave number and tends to saturate. For typical parameters the growth rate of the instability acquires values comparable to a fraction of the plasma frequency.

PHY93-Generation of mega Gauss magnetic fields by self focused q-Gaussian laser beams in preformed plasma channels

Naveen Gupta* and Pooja Devi Lovely Professional University, Phagwara

E-mail: naveens222@rediffmail.com, devip7303@gmail.com Abstract A scheme to generate giant magnetic fields of the order of Mega Gauss by using nonlinear laser plasma interaction has been presented. When laser beam with non uniform intensity profile propagates through a preformed plasma channel, the intensity gradient over its cross section makes the dc component of the ponderomotive force finite. This result in modification of the dielectric function of the channel is such a way that the laser beam gets self focused. At the focal spots of the laser beam the high filed intensity results in axial motion of the electrons that give rise to giant azimuthal magnetic fields. Following Virial theorem the semi analytical solution of the nonlinear wave equation for the field of laser beam has been obtained. Emphases are put on investigating the effect of laser and channel parameters on the longitudinal and radial variations of the strength of the generated magnetic field.

Abstract Lead free titanate materials are most widely used due to its adaptability and as a substitute to the lead based materials. As lead based material has many applications like piezoelectric actuators, sensors and transducers, but due to the toxicity of lead, it poses great threat to the environment. There is a great need of developing piezoelectric materials that are biocompatible and environmentally friendly. Lead free materials are the good substitute to these materials. Polycrystalline ceramic of lead free titanate i.e. strontium calcium titanate has been prepared by using solid state reaction (SSR) technique. SSR method involves weighing, mixing and milling of the reactants by using distilled water according to stoichiometric proportions and the slurry that is obtained after milling is dried on hot plate. The prepared material is then calcined and is followed by structural, optical and thermal characterizations. The structural studies i.e. powder X-ray diffraction has been carried out by using powder X-ray diffractometer through which lattice parameter, crystal structure and crystallite size has been calculated. The optical studies i.e. UV-Vis spectroscopic studies of the prepared material has been done by using UV-Vis spectrophotometer through which band gap of the prepared material has been calculated by considering direct transition between the valance band and conduction band using a Tauc’s method. The detailed results will be presented and discussed.

Abstract We have developed a theory of excitation of electron Bernstein waves in a magnetized plasma slab by a relativistic electron beam with taking the distribution function of loss cone velocity. For describing the plasma background, we have taken the parabolic density profile and electron beam of uniform density and finite width is assumed. Here, we use the kinetic theory for solving the equation of motion and to obtain the beam response to the field of the Bernstein wave. The Bernstein wave is excited by the slow space charge and having large 𝑘⊥ the electron beam of uniform density and finite width is assumed. The growth rate has been calculated for the Cerenkov and slow cyclotron interactions of beam plasma system in infinite medium which is proportional to 𝜔𝑏0

1/3 and 𝜔𝑏0 respectively.

Abstract To operate various electronic devices in harsh conditions highly efficient and long duration energy storage devices are needed. Supercapacitor, also called electrochemical capacitor is one of the most promising energy storage devices for providing high electrical power and offer long operating lifetimes. The energy density and duration of commercial energy storage devices like capacitors, batteries etc. is limited. Compared to rechargeable batteries, supercapacitors carry much higher specific power density (per unit mass) and energy/power efficiency, faster charge/ discharge rate. The improvement in the electric conductivity and specific capacitance of the active electrode materials used in the supercapacitors, usually arises by combination of mechanism observed in double layer and pseudo capacitance near the electrode/electrolyte interfaces. Among the various developed materials so far, Vanadium oxide (V2O5) is one of promising candidate for super capacitor applications because of exceptional physicochemical properties. These electrochemical properties usually enhance at nano scale and depend on the surface characteristics of synthesized material. In the present work V2O5 has been synthesized via hydrothermal treatment of Sodium meta vanadate (NaVO3) in specially designed autoclave. The detailed study on the effect of crystallite size, shape and surface characteristics on electrochemical properties have been done. The electrochemical characteristics studied via cyclic voltammetry (CV) in a fixed voltage window for different scan rates and CV cycles has been studied in detail. The electric double layer capacitance (EDLC) and supercapacitor characteristics of the synthesized phase has been determined. The charge/discharge studies have also been done to increase the applicability of the synthesized material as electrode material for low cost batteries. The comparison of synthesized shape controlled V2O5 with stable pure phase commercially available V2O5 has been emphasized. The enhancement in storage capacity with incorporation of carbon support has been studied in detail.

Andrews McEwan*, Tirth Dalwadi, Het Shah Anand Niketan Maninagar Campus, Hathijan, Ahmedabad, Gujarat.

Abstract In this paper, we bring forth the Young modulus of RNA nanowire (NWs) as a function of diameter considering the surface stress effects. A good trend between the present calculated and the available theoretical size-dependent Young’s modulus of different NWs is found including the DNA NWs, which supports our current effort of predicting the mechanical strength of the RNA NWs. Our horizons have been stretched to predict the behavior of the RNA NWs and see their resemblance to the behavior of either metallic or semiconducting nature of NWs which helps us in modelling RNA NWs for various electronic device applications.

Abstract ZnO, a wide band (~3.4eV) direct semiconductor with ~600meV exciton binding energy is an important material for the realization of number of optoelectronic devices. The device grade ZnO can be synthesized by number of techniques which makes it more versatile because its properties can be tailored by synthesis technique. In the present study ZnO nanophosphor was prepared by wet chemical method followed by sintering in air at 500oC. The synthesized powder samples were characterized by XRD, EDX, SEM and impedance spectroscopy. EDX investigation rules out any significant impurity in the material while XRD authenticated the Wuzrite structure of the synthesized material. On the other hand, SEM images confirmed the nano-structured nature of the prepared samples Electrical properties like A.C electrical conductivity, impedance, electric modulus and dielectric constant were investigated at two sample temperatures (120 and 500oC) in the frequency range 100-120 MHz using samples in the form of pellets. Decrease in the dielectric constant and dielectric loss was observed with the increases in frequency while the capacitance increased with the decrease in the frequency. The observed changes in the electrical properties could be due to defects, vacancies and microspores grains and interface state localized between two adjacent grains. The probable mechanism responsible for the observed behavior of the electric properties as a function of temperature and frequency are discussed.

E-mail: Suman.rani@lpu.co.in Abstract Undoped Zinc Sulphide (ZnS) and La doped ZnS (Lax: Zn1-xS where x=0.1, 0.5 and 1.0 mol %) were synthesized by co precipitation method followed by sintering (120oC max) in air. All the sintered powder samples were characterized by XRD, FTIR and UV-VIS techniques. From the XRD analysis of La: ZnS, it was concluded that crystal structure of ZnS remain same on doping and has Zinc blende structure. The crystallite size of undoped ZnS is 2.41 nm whereas La doped ZnS is 4.16 nm for (111) peak. Increase in size was attributed to the fact that ionic size of La is 1.03 Ȧ as compared to ionic radius of Zn (0.74Ȧ). FTIR spectra has major peak at 661 cm-1 is attributed to Zn-S stretching bond which confirms the formation of ZnS particles. UV-VIS spectrum of undoped ZnS has strong band edge absorption in UV region around 235 nm. Absorption edge get broaden on La doping which is due to the increase of defect states in ZnS. From the XRD data, the dislocation density was determined from the Williamson and Small man’s formula. Dislocation density was decreased on doping. This might be due to the higher crystal growth in size on doping which leads to better lattice quality than the undoped ZnS.

Abstract A ferrite is a ferromagnetic material more like ceramic have large proportion of iron oxide (Fe2O3, rust) with some amount of other metals as barium, manganese, nickel, and zinc. Ferrites are being considered as prominent material because of high electrical resistivity and good chemical stability. Manganese, a great candidate in electrochemical devices has also attracted a great attention towards energy storage devices. Manganese materials are proving to be a better choice in various devices because of more number of oxidation states which enhance the redox faradaic reactions. In this paper highly porous manganese ferrite was synthesized using simple and environmental friendly one step hydrothermal method. The synthesized material was characterized for the material properties using Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The morphology studies were carried out using Scanning electron microscopy (FeSEM). The electrochemical properties were studied using cyclic voltammetry.

Abstract Selective near infrared wavelengths have been studied to enhance the predictive capacity and post harvest quality of agri-products. This study used selected wavelengths in near infrared region for simultaneous prediction of the quality parameters (crude protein, fat, carbohydrate and moisture content) of wheat stored at 20°C temperature for one year. Spectra collected using lab built near infrared spectrophotometer were analyzed using classification methods and statistical model was prepared using regression techniques like partial least square and principal component regression. Principal component classified the wheat samples with respect to storage time. Principal component and partial least square regression model were developed using full spectra as well as selective wavelengths for determination of the parameters. Partial least square regression and principal component regression models shows that the model developed using selective 8-11 wavelengths increases the accuracy of the model as the root mean square error RMSE of validation decreases and coefficient of correlation increases.

Department of Zoology, Lovely Professional University, Phagwara, India

Abstract

Presence of antibiotics in water bodies has received widespread attention due to their potential toxicity. In this study adsorption capacity of synthesized beads were investigated, which were prepared by using chitosan, almond and walnut shell powder. The properties of the beads were characterized using Energy dispersive X-Ray spectroscopy (EDX), Scanning Electron Microscope (SEM) and Fourier-transform infrared spectroscopy analyses (FTIR). The functioning of beads was attributed towards its antibiotic adsorption. To study the effect of dosage, pH, initial concentration and time on antibiotic adsorption a batch adsorption experiment was conducted. Adsorption isotherms and kinetics were also studied. The adsorption isotherm experimental data is aligned with Langmuir for AWC (50% almond shell: 25% walnut shell: 25% chitosan) and CAW (50% chitosan: 25% almond shell: 25% walnut shell) beads and WAC (50% walnut: 25% almond shell: 25% chitosan) beads follow both Langmuir and Freundlich respectively. The pseudo-second order kinetic model fitted for all the experimental data. When present at low initial concentrations beads were promising materials for the removal of antibiotics from contaminated water.

Abhinav Kumar, Umar Mushtaq, JVM Lal Jeyan, Yogesh Khatter School of Mechanical Engineering, Lovely Professional University, Punjab,

India

Abstract Helium has been extensively used in cryogenic applications like to cool low temperature superconducting systems, MRI machines, ITER tokomak and Large Hadron Collider (LHC). It has been used in liquid, superfluid and supercritical state in order to maintain the temperature of the working system by extracting generated heat due to the circulation of large currents. Cooling through Liquid Helium (LHe) is much challenging due to the involvement of multi-phase physics during boiling process. Superfluid Helium (SFHe) is widely employed in LHC to cool the superconducting magnet at 1.9 K, exists below Lambda point (2.17 K) where substantial discontinuity in heat capacity occurs and viscosity of fluid becomes zero. Supercritical Helium (SHe) is mostly employed in various applications in order to avoid the challenges related to the boiling phenomenon in case of liquid state. Therefore, in this manuscript, thermodynamic and transport properties of SHe have been studied in supercritical state and an attempt has been made to develop an analytical temperature and pressure dependent expression for the properties such that these can be directly coded to the material library while performing the computational analysis.

Abstract High nitrate levels in ground water may pose a risk to human health and is toxic to livestock and human. Nitrate concentration in water samples was evaluated by colorimetric method. Nitrate poisoning in infant animals including humans can cause serious health problem and even death. The lower acidity in an infant’s intestinal tract permits the growth of nitrate reducing bacteria that convert the nitrate to nitrite, which is then absorbed into the blood stream. These nitrites react with secondary amines present in food and form carcinogenic nitric compounds. Nitrite has a greater affinity for hemoglobin than oxygen and thus replace the oxygen in the blood. Because of oxygen starvation a bluish discoloration of the body occurs. Nitrate poisoning has been referred to as the blue baby syndrome or methaemoglobinaemia. Nitrate poisoning is also known to cause gastrointestinal troubles, nausea, vomiting and headache. In the present study an attempt was made for the removal of nitrate in water using powdered orange peel by colorimetric method.

CHE15-Synthesis, characterization and application of zeolitic imidazole framework-mesoporous silica nanospheres composite: A hybrid porous composite for drug delivery

Chandan Adhikari and Anjan Chakraborty Department of Chemistry

Lovely Professional University, Jalandhar, Punjab

Abstract

Drug delivery system composed of mesoporous silica nanoparticles suffers from many drawbacks. Out of many challenges, two major challenges in drug delivery through mesoporous silica nanoparticles, are premature leakage and fast release of the drug molecules. Because of these, most of the time, efficiency of the drug delivery system become very low. In this work, mesoporous silica nanoparticles (MSN) have been modified using zeolitic imidazole framework through formation of a hybrid system. An anticancer drug Doxorubicin was encapsulated in mesoporous silica nanoparticles. Two zeolitic imidazole frameworks, ZIF-7 and ZIF-8 were prepared and used to form composite with mesoporous silica nanoparticles. The composites were characterized using scanning electron microscope, confocal laser scanning microscope, bright field imaging, powder X-ray diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis. BET surface analysis was conducted to understand the pore size, pore volume and surface area of the composite materials. The drug delivery study was conducted under pH stimuli as well as in present of liposome. The bare MSN were found to release the drug within 2-3 hours at pH~4 and in presence of liposome. But both the composites were found to control the drug release over a period of 12 hours at pH~4 and over a period of 7 hours in presence of liposome, which are almost 4 times slower release than bare mesoporous silica nanoparticles. This indicates that composite system has enough control on the drug release over the conventional drug delivery through bare mesoporous silica nanoparticles. This phenomenon was explained based on that, the ZIF frameworks act as a shield against the external stimuli and protects the bare silica from contact with the external agent and results in slower drug release. But in case of bare silica due to the absence of this kind of protection, drug release becomes very fast under acidic conditions.

CHE16-Synthesis and spectroscopic properties of axial phenoxide and para amino phenoxide incorporated indium (III) porphyrins

Padma Dechan and Gauri Devi Bajju

Postgraduate Department of Chemistry, University of Jammu, Jammu-180006, India

Abstract

Tetrakis-4-methoxyphenyl indium (III) porphyrins containing phenolic and para amino phenolic moieties in the apical sites have been successfully prepared and characterized spectroscopically. The phases and structure evolutions of prepared porphyrins were deduced from powder X-ray diffraction (PXRD). The axial coordination of phenolic moieties induces slight shift of the 1H NMR signals of indium porphyrin macrocycles. The measurements of UV-Visible absorptions of porphyrins in CH2Cl2 and CH3COOC2H5 reflects that axially ligated metal chelates at neutral pH display hyperchromicity of absorption bands compared to unligated metal porphyrin. The most striking feature was the structural stability of indium porphyrins under basic (pH = 10) as well as acidic media (pH = 4). On the other hand, the metal free ligand 5, 10, 15, 20-Tetrakis-(4-methoxyphenyl) porphyrin, H2TMP (I) undergoes J type aggregation in acidic media (pH = 4). The robustness of indium porphyrins especially in acidic media are in strong contrary to other sitting atop (SAT) or out of plane (OOP) complexes which are usually demetallized under acidic pH. All the prepared macro rings exhibit negative solvatochromism reflected by the blue shift of absorption bands in CH3COOC2H5 (more polar) than in CH2Cl2

(less polar). The photoluminescence emissions in indium(III) species are significantly quenched relative to metal free ligand (I) due to internal heavy atom effect and distortion of ligand plane. The quenching of fluorescence bands are more pronounced in axially ligated metal porphyrins. The lesser excited state lifetimes of indium(III) porphyrins is ascribed to spin orbit coupling induced by indium(III) ions in the metal chelates. All these results suggests that synthesized complexes can be exploited as efficient photosensitizers for use in applications such as photodynamic therapy, as promising stable compounds to destroy cancerous cells and also as useful candidates for gamma radiotherapy of tumor cells.

Shikha Sharma, Devinder Singh Department of Chemistry, University of Jammu, Jammu-180006, India

Abstract

A systematic study of nanocrystalline manganite has been undertaken to analyse the effect of sintering temperature on the structural and magnetic properties. In order to acquire a series of samples with different particle sizes, the sample was prepared by a solution combustion method and was subjected to annealing at four different temperatures. Rietveld analysis of X-ray diffraction data confirmed the presence of orthorhombic symmetry with Pbnm space group for all the samples. A paramagnetic-ferromagnetic transition is shown by all our investigated compounds at low temperature. With increasing sintering temperature or particle size, the Curie temperature (Tc) was found to increase, which is attributed to the magnetically disordered surface layer. All the phases obey Curie-Weiss law in the high temperature region and the effective magnetic moment calculated from the high temperature paramagnetic region shows an increase with sintering temperature.

Abstract

The chemistry of dithiophosphates represents a challenging and exciting research topic in the field of inorganic and structural chemistry because of their diverse coordination pattern. Substituted aromatic dithiophosphates of transition metals have been shown to be strongly influenced by varying the substituents on the dithio ligands. Hirshfeld surface analysis has attracted great attention of organic chemists, materials scientists, physical and theoretical chemists and crystallographers. It has great utility in the understanding of intermolecular interactions in the context of crystal packing and in the utilisation of such understanding in the design of new solids with desired physical and chemical properties and understanding the intermolecular forces such as weak and strong hydrogen bonds, vander Waals forces. Hirshfeld Surface Analysis has proved a great boon particularly in understanding the influence of substituted dithio ligands on the metal complexes.

CHE26-Comparative study of different substituted aryl dithiophosphate complexes of antimony (III) by DFT and HSA

Anu Radha, Sushil K. Pandey Department of Chemistry, University of Jammu, Jammu–180006, India.

Abstract

Dithiophosphate complexes of antimony corresponding to the formula [(ArO)2PS2]3Sb were synthesized by reacting the triethylammonium salts of diphenyldithiophosphate and antimony trichloride in 3:1 ratio. Crystal structures of the complexes has been characterized by using single crystal X-ray analyses. DFT computational analysis of these synthesized complexes has been carried out in order to compare the stability of complexes. The density functional theory (DFT) has become an effective computational tool for determining the geometrical parameters such as bond angles, bond lengths, and atomic charges along with the computational spectroscopic analysis which can assist in the analysis of experimental data. The HOMO-LUMO energy gap calculated using this DFT analysis helps in predicting the stability of the complexes. Hirshfeld surfaces analysis (HSs) and derived from them 2D Fingerprint plots (FPs) are characteristic for a given molecule in a defined crystal environment. It gives us an idea about the various inter and intra-molecular interactions present in the crystal system.

Samriti Sharma, Meena Sharma Department of Chemistry, University of Jammu, Jammu- 180006, INDIA

Abstract

Volumetric properties of L-leucine in aqueous solution of ionic liquid have been investigated at six different temperatures (293.15-318.15 K). By using the density data various volumetric parameters i.e. apparent molar volume (𝑉𝛷), apparent molar volume at infinite dilution (𝑉𝑜

𝛷), transfer properties (𝑉𝑜𝛷,𝑡𝑟)

have been calculated. These calculated parameters have been discussed in terms of solute–solvent interactions existing in the studied system on the basis of co-sphere overlap model. We have also attempted to examine the temperature and concentration dependence of such interactions. Results obtained from the calculated parameters shows the dominance of hydrophilic-hydrophilic interactions in the ternary solution. ILs has been evinced to have a strong impact on bio-catalytic reactivity and structural stability of enzymes and proteins. Hence the valuable facts about the solute–solvent interactions will be obtained by thermodynamic studies of amino acid in aqueous solutions of ionic liquids. Further we evaluate the apparent molar expansivity (𝐸𝑜

𝛷) and Hepler's

constant (𝜕𝐸Ф°

𝜕𝑇)p to interpret the structure making/breaking nature of solute.

CHE32-Mechanistic investigation of the promotional role of manganese ions as dopants in supported palladium catalyst for reduction and oxidation

Manpreet Kaur, Satya Paul Department of Chemistry, University of Jammu, Jammu-180006, India.

Abstract

One of the most exciting challenges in the present era is to develop efficient heterogeneous catalysts with higher activity and selectivity due to the aspiration for energy-saving chemical processes. Many attempts have been made in this direction and one such attempt involves the use of dopants. Tuning the topological, chemical and electronic properties of a heterogeneous catalyst by the controlled incorporation of dopants into their structure has proved to be an effective approach during the past few decades. In comparison to the undoped catalysts, doped heterogeneous catalysts show better activity due to the symbiosis existing between the dopant ion and nano-metal/support. Because of such synergistic interactions, the properties of the individual metal or support material get altered by virtue of charge and energy transfer, resulting in the change in catalytic activities. Keeping these points in mind, we have synthesized Mn3+- and Mn2+-doped Pd@L-dopa functionalised ZnO coated Fe3O4 catalysts and compared the activities of these doped catalysts with their undoped counterpart for oxidation and reduction. Efforts have been made to get the mechanistic insight into the modification of supported Pd catalyst through manganese ions doping, and XPS spectra has proved to be a perfect guide in this step.

CHE33-Bimetallic Fe-Ni based magnetic nitrogen doped carbons: synthesis and application in C-N bond formation

Chandan Sharma, Satya Paul Department of Chemistry, University of Jammu, Jammu-180006, India

Abstract

Nitrogen-doped carbons emerged as a new type of materials in recent years, as these materials have extensive applications in the field of gas sensors, Li ion batteries, field emission devices, supports, supercapacitors, electrocatalysts etc. These materials have good electrical and physicochemical properties due to lone pair of electrons on nitrogen which shows conjugation with carbon π-system. These attractive features have made nitrogen-doped carbons (NDCs) a promising support material for supporting and stabilizing transition metal nanoparticles by preventing the agglomeration of the metal nanoparticles. In order to increase the thermal and oxidative stability, we have modified NDCs with Fe3O4which make them magnetic and easily separable as well. Keeping in view theimportance of NDCs, we have synthesized mono and bimetallic Fe-Ni immobilized magnetic-NDC catalysts and characterized by various modern techniques. The catalytic activity of all these catalysts was tested for various organic transformations and found them active in C-N coupling reactions. The catalytic efficiency was compared and synergism in case of bimetallic catalysts was studied thoroughly using XPS.

Surbhi Sharma, Satya Paul Department of Chemistry, University of Jammu, Jammu, 180006, India.

Abstract

Due to increasing concerns about the environmental impact of various industrial processes, tremendous efforts are being made to develop new processes that minimize the use of harmful processes in chemical synthesis. Due to number of advantages associated with heterogeneous catalysts such as easy recovery, recyclability and non-toxicity, their demand is clearly on rise, including in industries. In the past, heterogeneous catalysts have been developed by the immobilization of metallic species on inorganic materials (alumina, silica), metal organic frameworks or charcoal. For development of cleaner and sustainable chemistry, a considerable interest in natural polymers such as chitosan, cellulose, gelatin, collagen, starch and agarose is on rise. Efforts are being made to develop the heterogeneous catalysts by employing these natural polymers as supports to create environment-friendly and highly efficient catalysts. The natural polymers offer the advantages such as abundant availability, chemical stability, presence of stereogenic centres, surface morphologies that allow their functionalization and eco-friendly nature. These natural polymers supported heterogeneous catalysts have been employed widely to catalyze variety of organic transformations. The detailed applications of these catalysts in organic synthesis will be discussed.

CHE35-Development of waste derived support materials for the preparation of heterogeneous catalysts and their catalytic applications

Shally Sharma, Satya Paul Department of Chemistry, University of Jammu, Jammu-180006, India

Abstract

Waste management has always been a big problem in big cities. Large volume of waste materials has been produced from both large scale industrial and biological processes. Waste materials that can be generated from industrial processes are red mud, aluminium dross, fly ash, and raw blast furnace slag, and those which originate from biological sources include chicken egg shells, rice husk, banana peels, peanut shells and plants. Cost-effective and environmentally friendly catalysts have been developed by using various waste materials like dead leaves of plants, rice husk, chicken egg shells, fly ash etc. Carbon derived from waste biomass like dead leaves of plants serve as excellent support material for the preparation of supported catalysts due to its low cost, easy availability, large specific surface area, high porosity, excellent electron conductivity, and relative chemical inertness. The silica derived from rice husk ash (RHA) has been utilized as a catalyst support, adsorbent, and composite. Recently, numbers of reports have been available for the preparation of solid base catalysts from waste egg shells. These shells are the rich source of CaCO3, which can be thermally decomposed at high temperature to generate CaO, a solid base catalyst used for the production of biodiesel from methanol and soyabean oil. Details about the development of catalysts from waste materials and their applications will be discussed.

CHE36-Development of CuAg nanoparticles immobilized on modified graphene and its applications in organic transformations

Nitika Sharma, Sukanya Sharma and Satya Paul Department of Chemistry, University of Jammu, Jammu-180006, India

Abstract

Graphene is considered as one of the most promising materials in research due to its unique properties, such as high charge mobility, high mechanical resistance and larger surface area etc. Graphene oxide (GO), an oxidized form of graphene exhibited good catalytic activities for several organic transformations due to the presence of abundant functional groups and high surface area. The catalytic activity of graphene can be modified by doping it with heteroatom like nitrogen which helps in controlling its properties to make N-doped GO a highly effective and stable support material. N-Modified GO has additional benefits of introducing basic character to the support material, which in turn stabilizes the metal nanoparticles as well as avoids the use of additional base in stoichiometric amount. Also, modification with various inorganic materials would increase the surface area and thermal stability as well as prevent the leaching of nanoparticles. Keeping in view the above properties, we have developed Cu@Ag-TiO2-NGO and its catalytic activity was studied for oxidation as well as Chan-Lam coupling reactions. The prepared catalyst has been characterized by various techniques like FTIR, TGA, ICP-AES, BET, EDX, XRD, XPS, SEM and TEM. The details about the preparation, characterization of the catalyst as well as its application will be discussed.

The effect of co-doping of Zn2+/Zr4+ ions on the structural and magnetic properties of BaZnxZrxFe12-2xO19 (x= 0.00 to 1.00) synthesized using pechani method has been investigated. XRD data reveals that the samples are phase pure and have no traces of secondary phase such as α/γ-Fe2O3 and BaCO3 etc. The c/a parameter is <3.98 for all samples implying that they are M-type hexaferrites. FE-SEM micrographs reveal an increase in particle size with increase in Zn2+/Zr4+ dopant concentration. The local distortion of the crystal structure with increasing dopant ion concentration confirms by widening of Raman bands. Magnetic measurements reveal that the sample exhibit magnetic ordering. The coercivity value decreases from 5350 Oe to 763 Oe with increasing Zn2+/Zr4+ dopant concentration. The saturation magnetization (Ms) value has been found to be maximum (68.43 emu/g) in x=0.20 sample. These materials could be useful for magnetic recording applications. .

Two well known synthetic organic reactions Ramirez olefination and Corey-fuchs reactions are integrated in one-pot sequential manner for the synthesis of arylacetylenes starting directly from commercially available aldehydes. Bicyclic amidine 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) used along with NaOH afforded the terminal alkynes directly from the aldehydes. On the mechanistic note, tandem process involving ramirez olefination/ Corey-Fuchs reactions takes place in a single step to generate terminal alkynes from aldehydes. Our approach represents the method of preparation of biologically significant heterocyclic compounds by cyclization of hetero atom containing alkynes with π acidic metal salts because the starting materials are readily available and organometallic compound are useful synthetic intermediates.

University, Phagwara-144401, Punjab, India.

Abstract

Xanthine is generated from guanine and hypoxanthine by guanine deaminase and xanthine oxidase (XO), respectively. It serves as an indicator of spoilage of meat and various pathological conditions. An optical fibre optic biosensor has been developed for the determination of xanthine by absorption transmission approach. The conversion of xanthine to uric acid and H2O2 by XO has been used as a bioassay principle in this study. Due to the production of uric acid, pH of the reaction decreases and falls in range of 7.6 - 6. The absorptive dye phenol red has been screened to visualize the change in colour. The co-immobilization of XO and dye phenol red indicator was done with sol-gel method onto the circular plastic discs for the development of biosensor. Volume of sample required for detection has been miniaturized to 10µl. The linear concentration range of 0.5µM – 150µM with detection limit of 0.5 µM for xanthine has been achieved. The application of developed biosensor in meat sample is under progress. The study resulted in the development of a fast, reliable biosensor with miniaturized sample volume and mass scale screening possible through colour visualization.

CHE44-Development and application of nanostructured catalyst in the preparation of heterocycle

Neha Sharmaa, Monika Guptaa, Bushra Chowhana aDepartment of Chemistry, University of Jammu, Jammu-180006

Abstract

Catalysis is a process in which catalyst efficiently transforms the reactants into product without being consumed in the reaction. The indispensable need of present era to find a way for the sustainable development leads to maximize the use of Green Chemistry in catalysis. It paved the way for refinement of catalysis into nanocatalysis. These nanocatalysts possess high surface area to volume ratio which makes them highly efficient than conventional catalysts. But they lack recyclability. However, this demerit can be easily overcome by immobilizing the nanocatalysts over heterogeneous supports. These advantages made the heterogeneous nanocatalysts more superior and greener than homogeneous counterparts. Heterocyclic atoms containing compounds are the most abundant compounds found in the nature. Pyrido[2,3-d:5,6-d′]dipyrimidines are one of the nitrogen containing heterocyclic compounds possessing diverse biological properties such as anti-tumor, anti-allergic, anti-oxidant, anti-fungal, anti-microbial, anti-bacterial and anti-viral activities. In view of above, we developed a ionic liquid coated ferrite based magnetically separable nanocatalyst and explored its catalytic activity for the synthesis of pyrido[2,3-d:5,6-d′]dipyrimidine. The catalyst is also recyclable upto 8 runs without much loss of activity which makes our catalyst economical and sustainable.

Harsh Kumar, Gagandeep Kaur Department of Chemistry Dr B R Ambedkar National Institute of

Technology Jalandhar 144011 Punjab Abstract

Surfactants can be considered as important class of chemical species having a polar head and non-polar tail, which make it capable to be utilized in many industrial formulations such as coatings, paints, lubricants and cosmetics etc. On the other hand, ionic liquids, which are actually molten salts, are also having many useful properties such as negligible vapor pressure, high thermal stability etc. They can modify the physiological as well as aggregation properties of conventional surfactants according to our desire. The mixtures of ionic liquids with surfactant are found to be better systems for many industrial applications than individual ones. Thus the aggregation behavior and thermodynamic properties of sodium tetradecyl sulfate STS are investigated in the presence of 1-propyl-3-methylimidazolium bromide [C3mim][Br] in aqueous media. For this, ionic liquid 1-propyl-3-methylimidazolium bromide [C3mim][Br] is synthesized in our lab. Then the conductivity measurement is done to determine the critical micelle concentration (CMC) of sodium tetradecyl sulfate STS in the absence and presence of (0.02, 0.05 and 0.1) wt. %, of 1-propyl-3-methylimidazolium bromide [C3mim][Br] in aqueous medium at three different temperatures i.e. 298.15K, 303.15K and 308.15K. The results are then utilized to find various thermodynamic parameters of micellization such as, standard free energy of micellization, standard enthalpy of micellization and standard entropy of micellization, which are important to understand the driving force behind the process of micellization.

PG department of chemistry, university of jammu, jammu-180006

Abstract

The field of nanocatalysis has undergone an explosive growth during the past decade. Since nanoparticles have a large surface to volume ratio compared to bulk particles, they are attractive candidates for the use of catalyst. It takes a lead over the homogenous counterpart due to easy recovery, ease of workup, high surface area, etc. Nanocatalysis is a growing field in chemistry and it attracts the attention of chemists now-a-days. It plays a pivotal role in variety of organic transformations. Heterogeneous nanocatalysis involves the combined effect which makes the process cost effective and constitutes an important pillar of green chemistry. Oxygen containing nucleus is a fertile source of biologically important molecules possessing a wide spectrum of biological and pharmacological activities, such as anti-microbial, antioxidant, antiviral, sex pheromone, cancer therapy, antiproliferative and central nervous system activity. Some of these compounds are widely employed as cosmetics and pigments and as potential biodegradable agrochemicals. Numerous literature methods have been reported for the synthesis of pyran derivatives using different catalysts and reagents but those suffer from certain drawbacks such as use of homogeneous catalyst, longer reaction time, tedious work-up procedure, harsh reaction conditions, use of base, etc. In order to cumbersome those drawbacks, here we will try to report palladium catalyzed pyran synthesis using aromatic aldehydes, active methylene compounds and ethyl acetoacetate. Amines are valuable building blocks for manufacturing of pharmaceuticals, pigments, agrochemicals and numerous types of other chemicals. Among the amine family, anilines occupy a special place because they are important raw materials in various fields with the production over 4,000,000 tonnes per year. The reduction of nitroarenes is the common route for the synthesis of aniline derivatives and we tried to synthesis substituted aniline from substituted nitro compounds using Palladium catalyst in presence of hydride donor as reducing agent. Moreover, the catalyst is found to be recyclable for various runs without much loss of activity what made the process cost- effective and fall in the area of Green chemistry.

CHE54-Zinc porphyrin; axial coordination of pyridine and phenol donors: spectroscopic thermal and biological characterizations

Devika Sharma, Sujata Kundan Department of Chemistry and Chemical Sciences, Central University of

Jammu, Jammu

Abstract

The best brains of the time struggled to find out the answers of two very simple questions, why does grass have a green colour? And why does blood have a red colour? Soon it was realized that just one family of pigments is responsible for the red colour of our blood and the green colour of grass. These are regarded as porphyrins and are aptly termed as ‘Pigments of life’. They were so brilliantly colored and colorfast that they quickly became a luxury, “Royal Purple”. Porphyrins can take on an amazing variety of roles in the real world, which is why they are widely utilized and researched. Reaction of zincII-5,10,15,20-meso-unsubstituted-tetraphenylporphyrins [H2-tPP] with nitrogens and oxygens in 1:1 molar ratio result in the formation of five-coordinated axially ligated zincII-meso-unsubstituted-tetraphenylporphyrins [X/Xʹ-Zn-tPP] [X/Xʹ = different nitrogen and oxygen as axial ligands]. The absorption spectra shows B(0,0) > Q(0,0) > Q(1,0) as absorbance order, and oscillator strength (ƒ) reveals the relative strength of π → π* interactions. The fluorescence spectra exhibit two fluorescence bands [S2→S0 and S1→S0] with emission ranging from 550-700nm. IR Spectra confirms ν(Zn-NPor), ν(Zn-OPh) and ν(Zn–NPy) at 650-570cm-1, 650-350cm-1, 500-400cm-1 respectively. 1HNMR spectra confirm the merging of protons of pyridine and phenolic ring with the tetraphenyl rings of the porphyrin moiety. The 13CNMR indicate 13C resonance signals between 0ppm-200ppm. The percentage of each element is confirmed by elemental analysis at about 1000oC using helium as carrier gas and oxygen for combustion. Thermal studies of these porphyrins were carried out in an argon atmosphere from room temperature to 800oC, which shows a continuous weight loss; when a stable oxide of ZnO is formed at particular temperature depend upon the porphyrin formed using thermal analyzer. Some of the synthesized zincII-porphyrins complexes have also been screened for various biological activities include antioxidant, antifungal, antiproliferative and antibacterial. The Invitro antioxidant activity was studied by DPPH dye method and Invitro antifungal by DDM method. Some complexes were also screened for antibacterial activity with IZD range between 8mm and 16mm depending on the nature of the axial ligands that affect the IZD of the respective bacterial stain.

CHE58-Treatment of azo-dye wastewater by advanced oxidation process

Makarand Patil, Harminder Singh School of Chemical Engineering Sciences and Physical Sciences, Lovely

Professional university, Punjab

Abstract

Azo dyes are among the chief environmental pollutants. The textile industry is the greatest source of azo dyes in wastewater as it uses substantial amount of water in its manufacturing processes. Azo dyes are employed in wide range of industries with potential applications in textiles, papers, plastics, printing ink, food stuff, leather, paint, etc. A large portion of the dye is washed out and hence ends in wastewater. These dyes are non-biodegradable and hence accumulate in the environment aver a period of time and this may be a threat to ecosystem. This accumulation of dye lets to serious environmental problems. The primitive processes (physical/chemical) for the treatment of azo dye are not eco-friendly and uneconomical as well. Modern processes like the use of enzymes and Advanced Oxidation Processes seem to be the desired ones. Various advanced oxidation process like Fenton, Electro oxidation, ultrasonic, photo-catalysis etc. have been proved efficient in treatment of azo dyes. In this study we focus on the treatment of acid orange 7 and acid red 88 azo-dyes which are prominent among azo dyes in textiles industries by combination of AOPs. Experiments had been carried out on synthetic water of dyes and treated by aeration followed by Fenton’s reagent in presence of UV light. Parameters like BOD, COD, pH turbidity, and color removal are studied. It was found that around COD removal of 83 %, and color removal was observed. Turbidity was found to be increased, it indicates dye degradation.

cPunjab Engineering College, Chandigarh, 160012 Abstract: FITC dye loaded mesoporous silica particles (MCM-41/FITC) have been synthesized using (3-Aminopropyl) trimethoxysilane (λex = 490nm and λem = 512nm). The loading of FITC in the pores of MCM-41 particles and the synthesis of blue emitting carbon quantum dots (B-CQDs) has been confirmed by different advanced characterization techniques. The B-CQDs are conjugated with the MCM-41/FITC particles. The as-synthesized MCM-41/FITC, B-CQDs and conjugated particles are characterized using the different analytical techniques such as UV-Illuminator, dynamic light scattering, UV-absorbance, and photoluminiscence spectroscopy. In the UV-absorption spectra, the peak at λ =368 nm confirms the formation of B-CQDs. Upon excitation at λex=330 nm, B-CQDs delivered the highest emission intensity at λem 430 nm. After the conjuagtion of B-CQDs with MCM-41/FITC particles, the dual emisssion at wavelengths 439 nm and 516 nm for blue and green emission (λex 330 nm), respectively is confirmed. This blue-green dual emitting probe can further be utilized for nitroaromatic explosive detection application.

Abstract:

Textile industries are the major consumers of dyestuffs. During the coloration process, 10 to 15 percent of the dyes will be lost and this will be discharged with the effluents coming from textile industries. These are very difficult to degrade and they may degrade to form products that are highly toxic to human. Ion-exchange materials play an important role in environmental, agricultural and other industries including wastewater treatment, ion pollutant removal, and ion separation from aqueous solutions to boost product yields and reduce the production time for industrial process.

Graphene-based magnetic hybrid nanocomposite has the advantage of exhibiting better performance as platform or supporting materials to develop novel properties of composite by increasing sensitivity of the targeted adsorbate. The hybrid nanomaterial was prepared by mixing iron (II) and iron (III) salt precursors in the presence of GO dispersion through coprecipitation method followed by in situ chemical reduction of GO. The effect of weight loading ratio of Fe3O4 to GO (1:1, 5:1, 15:1) on structural properties of the hybrid ion exchange nanomaterials was investigated. The structure of magnetic nanocomposites were characterized by X-ray powder diffraction (XRD), Fourier transformation infrared spectroscopy (FTIR), Raman spectroscopy, Scanning electron microscopy (SEM), and atomic force microscopy (AFM). In this work, magnetic graphene based ion exchange nanomaterials were used as an effective adsorbent for anionic Congo red dye removal. Batch adsorption experiments were performed with the variation of initial dye concentration, pH, adsorbent dosage and incubation time. Furthermore, the desorption of congo red was preliminarily studied. The adsorption and removal efficiency congo red by magnetic anion exchangers (MAE) was found to be 86-90% and 15-22% at pH 3.0 and 7.0, respectively. The nanocomposites is magnetically separated and reused. Thus, it would be a promising adsorbent for removing organic pollutants in water.

Abstract

The spinel ferrites are the magnetic materials having chemical formula AB2O4, where A and B represents the divalent and trivalent cation respectively. The spinel ferrites has been classified into 3 categories due to distribution of cations in octahedral (B) and tetrahedral (A) sites; inverse, normal and mixed spinel ferrites. They have various applications in ferrofluids, inductors, catalysis, digital recording, electronic devices such as sensors and biosensors etc. In the present study, Gd3+ doped Nickel ferrite have been synthesized by glycine nitrate combustion method. The room temperature X-ray diffraction data were analyzed with the Rietveld analysis program GSAS for the structure determination. The phases crystallize in Fd3-m space group with cubic symmetry. No regular trend in the lattice parameter a with Gd3+ doping has been observed. The magnetic studies at room temperature using Vibrating Sample Magnetometer (VSM) showed a decrease in saturation magnetisation with Gd3+ doping. Substitution of Gd3+ in Ni-Cr ferrite further enhances coercivity thereby making the materials magnetically more hard. The Topography and elemental analysis for the prepared phases were made by SEM and EDX techniques. Grain size was calculated by using TEM.

Abstract Nanocatalysis is a fascinating area and occupies a unique place in chemistry. Moreover, in these environmentally conscious days, one of the main challenges towards the chemists is to develop an efficient technologies which lead scientist to study a new area called green chemistry which was coined by Sir Paul T Anastas. Heterogeneous catalysis is the fundamental pillar of Green Chemistry. It takes a lead over the homogeneous counterpart due to easy recovery, ease of workup, high surface area, etc. Heterocycles are important class of organic compounds which are found to possess broad range of biological activities including anti-viral, anti-microbial, anti-cancer, anti-diabetic, anti-tubercular, antidote, anti-leishmanial, anti-oxidant etc. Various methods have been reported for the synthesis of heterocyclic compounds using different catalysts and reagents. Here, we present the synthesis, characterization of immobilized heterogeneous nanocatalysts and its applications in the synthesis of heterocycles. Moreover, the catalyst is found to be recyclable for various consecutive runs what made the process cost effective and fall in the area of Green Chemistry.

Abstract

Metal complexes with heterocyclic Schiff bases are of substantial curiosity for the chemists. Ligand modifications are easily accessible due to preparative simplicity, structural variability and tuneable electronic properties. Hetero atoms like N and O when incorporated in Schiff bases play a key role at binding sites in metallobiomolecules. As transition metals form an integral part of biological system and their mixed ligand complexes with Schiff bases are known to have remarkable application in biological fields as antibacterial, antifungal, anti-inflammatory and as anticancerous agents. Keeping in mind their marked biological activity, this work reports the synthesis and characterization and antimicrobial activity of mixed ligand complexes of zinc and copper with Schiff base (obtained by the condensation of glyoxal with ortho and para anisidine) as primary and N, N' donor molecules as secondary ligands.

Sciences, Lovely Professional University, Phagwara.144411, Punjab, India.

Abstract In the present investigation conductance and speed of sound of aluminium sulphate, aluminium nitrate, and aluminium chloride were experimentally determined in water and binary aqueous mixtures of THF. Various conductance and acoustic parameters viz; molar conductance, limiting molar conductance, partial molar adiabatic compressibility, coefficient of adiabatic compressibility were also determined by using Kohlrausch&#39;s Law, Debye- Huckel theory and Masson’s equation at working temperatures and different compositions of THF. Analysis reveals that limiting molar conductivity () decreases with increase in composition of THF in water indicating the decrease in the ion-solvent interactions with increase in composition THF in water. Further it was found that with increase in temperature the values increase for all the three salts which support the increase in ion-solvent interactions with increase in temperature. The values of partial molar isentropic compression ( ) were found negative and these values further increase with increase in composition of THF indicating that on increase in composition, attractive interactions develop between THF and Water which induces dehydration of aluminium salts which make the water molecules of aluminium salts more compressible than that of lower THF concentration resulting in decrease of ion solvent interactions with increase in THF composition in water. On the other hand with increase in temperature, the values of further increase leading to increase in ion-solvent interactions of aluminium salts in water and 5% THF+ water. Walden product and its temperature coefficient i.e.[d()/dT] have also been calculated which confirms that aluminium salts act as structure breaker in different compositions of THF in water.

Abstract

Green coffee (GC) beans are rich source of phenolic compounds that act as antioxidants. Among many phenolic compounds, chlorogenic acids are present in GC that have strong antioxidant properties and prevent neurodegenerative diseases, fat accumulation and stroke. However, after processing of GC beans, many antioxidants inherent to GC beans are lost. It is estimated that chlorogenic acids decreases approximately 40-fold in the amount. Encouraged with much required green technology approach, research interest in field of natural plant-based medicine is increasing day by day. Thus, extraction and characterization of GC beans is carried out to recover valuable antioxidants in coffee beans. In this work, aqueous extraction of GC beans was carried out using microwave extraction. Aqueous extract of GC was further sequentially fractionated for separating antioxidant compounds from crude extract on polarity basis. The obtained extract fractions were further analyzed for quantitative and qualitative analysis of bioactive polyphenol. The GC extracts were characterized for the bioactive compounds by Fourier transformation infrared spectroscopy (FTIR) and Thin layer chromatography (TLC). The antioxidant activity, total phenolic content (mg/g of gallic acid) and chlorogenic acid were found to be highest in aqueous extract i.e. 80.3± 0.4 %, 3.5mg/g and 9.25± 0.2% respectively.

Abstract In this study, we have investigated the photoelectrochemical (PEC) water splitting activity of dye sensitized ZnO nanorods. Seed layer of ZnO was spin coated on Indium Tin Oxide coated glass (ITO) substrate and then ZnO nanorods were fabricated by Chemical Bath Deposition method at 90⁰C under different conditions. As synthesized ZnO rods were subjected to XRD for phase and orientation analysis, FE-SEM for morphological analysis. XRD pattern confirmed hexagonal wurtzite structure with preferential growth along (002) direction. SEM images showed that dimension and shape can be controlled by optimising reaction time and reaction conditions. Current voltage characteristics were recorded by using Rose Bengal dye sensitized ZnO nanorods as working electrode in three electrode cell. Different photocurrent and photovoltage were recorded for different ZnO nanorods. Our results show that PEC activity can be optimized by changing the morphology of ZnO nanorods.

Department of Chemistry, Lovely Professional University, Phagwara, Punjab, India

Abstract

The formation and depletion of NaH2+ (1A') is proposed to have a crucial role

in the chemistry of interstellar medium [1-4]. To have a better understanding of these processes a three dimensional global analytical potential energy surface (PES) has been constructed for the NaH2

+ (1A') molecular ion. The PES is made by computing 3000 abinitio points at different nuclear geometry in multi reference configuration interaction (MRCI) level of theory followed by fitting the abinitio points to a set of polynomial functions. It has been identified that the two asymptotes of the NaH2

+ (1A') represents the NaH+ + H and Na+ + H2, respectively. Various spectroscopic propertied like dissociation energies, zero point energies, bond lengths of LiH+ and H2 obtained from the PES is found to be in good agreement with the available literature data.

Abstract

Bitumen is used as a binder in construction of flexible pavements since long. With the increase in population and number of vehicles, load on roads have been increased day by day. Thus, roads which consist of unmodified bitumen suffer from serious drawbacks in the due course of time like rutting, thermal cracking, fatigue cracking, pothole formation etc. Hence, it is necessary to add a modifier in bitumen to enhance the binding property of later. Polyethylene, which is a non-degradable compound, become waste and create pollution, owing to its high consumption. This polyethylene (melting point 120-180 °C; thermal degradation above 400 °C) in liquid state becomes sticky in nature and therefore can act as a binder. Also, major parts of both polyethylene and bitumen are hydrocarbon, hence polyethylene wastes (LDPE and HDPE) can be used to modify the bitumen and enhance the binder property of it. Like polyethenes, degradation of other polymeric wastes is also challenging and can be utilized for other purposes for minimizing the wastes and improvement in quality of available products.

Abstract Nanoparticles (NPs) are ubiquitous in nature. They are used in a wide range of applications. This review represents a comparative study of the applications as well as the adverse effects of silver (Ag) and zinc (Zn) NPs on living organisms and the environment. These materials are used in agricultural engineering, industries, medical instruments, biomedical treatments, cosmetics, sensor technology, paints, deodorants, room sprays, food preservatives, in buffering environmental systems and water treatment and hence are very important for scientists and industrialists in this era. Ag-NPs are well-known for their antibacterial and antimicrobial properties. They also show unique physicochemical, optical and electrical characteristics. Although, excessive use of these materials showed adverse effects. For example, Ag-NPs cross the blood-brain barrier (BBB) and enter into human brain causing neurotoxicity by weakening the mitochondrial functions and induce gliosis. Whereas, Zn-NPs are enlisted as ‘Generally Recognised as Safe (GRAS)’ by ‘Food and Drug Association of United States (FDA, US)’. Hence, biosensors constructed using Zn-NPs, can be employed in various agriculture and biomedical applications. For example, these biosensors can be used in detecting pesticide residues in the soil, soil moisture and the specific amount of the soil nutrients. Zn-NPs promote seed germination, seedling vigour and boost the yield. These (i.e. Zn-NPs) help in the growth of food crops and in the disposal of aquatic weeds which are resistant to other weedicides.

E-mail: nupur.20362@lpu.co.in

Abstract

Bulk-Metallic-Glasses (BMGs) are metals and their alloys in frozen-state having no long range of molecular arrangement. They are used for a wide range of applications because of their unique properties e.g. BMGs resist failure against applied which is termed as high fracture strength. They also show high corrosion resistance and good machinability. They are used in the fabrication of various magnetic devices e.g. magnetic inductor cores, choke coil cores. Hence, several processes have been developed for the synthesis of these materials. For example, Splat-cooling, Water-quenching, Arc-casting, Gas-atomizing, Thermal-spray-coating, Laser-direct-deposition are few common methods of synthesis of BMGs. These methods are ways to avoid crystallisation. A host of advanced materials characterisation techniques are used to study these materials. Here, use of Fourier Transform Infrared Spectroscopy (FTIR) for the characterisation of BMGs will be reviewed. FTIR can be used for studying the chemical composition of materials as it senses the presence of any moiety which changes its dipole moment when interacts with infrared radiations. In case of BMGs’ study, FTIR is used for detection of presence of various wanted or unwanted materials in the BMGs or any product made of BMGs. For example, X-ray Diffraction technique cannot be used for the detection amorphous phases present in rust, but it can be detected by FTIR because the identification of moiety depends upon the vibration of molecules.

CHM04-Recent advances in enzymatic saccharification of lignocellulosic biomass for biofuel production

Sonali, Richa Arora

School of Bioengineering and Biosciences, Lovely Professional University, Phagwara, India

Abstract

India being an agricultural economy has plenty of lignocellulosic biomass (LCB) such as agricultural waste which can be utilized for biofuel production. Despite abundant supply of LCB for biofuel production, challenges still exist owing to recalcitrance to degradation of lignin, heterogenous composition of hemicelluloses and highly crystalline structure of cellulose in lignocellulosic biomass which requires pre-treatment (chemical or physical), thereby, increases the cost of the entire process and prove to be a major hurdle for large scale production. The present review focuses on stratagems such as metabolic engineering, optimization of process parameters, mixed or coculture techniques, expressing recombinant or heterologous lignocellulolytic enzymes, biomass processing and genome-based breeding techniques for efficient delignification and detoxification of LCB, maximal enzymatic liberation of monosaccharide sugars and avoids production of inhibitory sugar derivatives for conversion to biofuel. Moreover, it also highlights the genetic modification of potential fermenting organisms such as Saccharomyces cerevisiae, Escherichia coli, Zymomonas mobilis, Pichia stipitis, Kluyveromyces marxianus to be cellulolytic to obtain more amounts of sugars. Enzymatic saccharification of LCB provides significant opportunities in increasing the yield of biofuel, replacing traditional chemicals which are environmentally hazardous while also making the process economically “green.”

CHM05-Catalytic upgradation of waste tyre pyrolysis oil

Shivangi Thapar Institute of Engineering and Technology, Patiala, Punjab 147004

Abstract

Around 1.5 billion waste tyres are generated globally every year and India accounts for around 6% of total waste tyre production. With phenomenal increase in number of automobiles in India during recent years, these statistics are expected to rise drastically. Apart from having large production volume, durability is also a concern, making it hard to dispose. The objective of the work is upgradation of the waste tyre oil to be used for commercial purposes as an alternative to the conventional fuel. The waste tyre oil was subjected to pyrolysis in the presence of nitrogen, both without and with the use of catalyst: ZSM-5, HY-Zeolite and Mordenite, in a fixed-bed reactor. The temperature range taken in consideration was 350⁰C to 500⁰C. When the reaction was carried out without the use of catalyst, there was no change observed in colour, odour and other physico-chemical properties. However, with the use of Mordenite at 450⁰C highest yield was obtained. The characteristics of oil also improved with the use of catalysts, particularly with mordenite.

Abstract Mechanical aerators are most commonly used for aeration process in treatment of waste water. Oxygen exchange mechanism by plunging jet of water is a superior method to transfer oxygen into pool of water than regular systems. Surface jet aerators, which are closed and simple systems, are uncomplicated in design, working and maintenance. In this study, experiments were conducted on models of solid jet aerators having circular shaped opening with variable jet lengths and area for different discharges. Penetration depth, oxygen transfer factor and Oxygenation efficiency were measured for different jet lengths, corresponding to each area and discharge. It was observed that penetration depth and oxygen transfer efficiency increments with increase in discharge and jet length in air whereas oxygen transfer factor increases with jet length in air only. Multiple non-linear regression modelling was applied to predict oxygenation performance of the aerator for different sets of input parameters. With the results achieved, an efficient aerator model was suggested for a given set of inflow and environmental conditions.

Abstract

An efficient transportation system is vital to economic development and a sustainable environment of a country. As per 2019 statistics, Gross Domestic Product (GDP) of India is $2.92 Trillion with a 5% growth rate. The transportation sector accounts for a share of 7.5% in India's GDP. India's road transportation contributes to approximately 5.4% of the GDP carrying 65% of freight traffic and 85% of passenger traffic. India's fuel imports are growing at an average of 18% annually for which India spends 3.5% of GDP. This causes a loss of 1.5% of GDP due to the rising fuel prices, thereby posing a major threat to the economy of the country in the future. Also, the use of such a high quantity of fuel causes vehicular pollution, which is responsible for almost 75% of carbon monoxide emission in urban areas worldwide. The study concentrates on carrying out an interdisciplinary work involving the sectors of transportation, energy, economy and environment considering the parameters like vehicle model split, fuel consumption, fuel cost and vehicular emission. This is done by building a System Dynamics (SD) forecasting model using STELLA software to mathematically forecast these parameters in the upcoming years. Hence, a scenario of augmenting the growth rate of public transportation and simultaneously restricting the growth rate of private transportation showed a substantial decrease in fuel consumption, fuel cost and vehicular emissions, which eventually resulted in an increase in GDP as well as a reduction in the vehicular emissions in the transportation system.

Abstract

Most heavy metals are well-known toxic and carcinogenic agents and when discharged into the wastewater represent a serious threat to the human population and the fauna and flora of the receiving water bodies. The development of a novel biofilter was aimed in this project. The various parameters of the biofiltration processes, their mechanism for heavy metals removal along with the efficiency of the biofilters and its scale up aspects have been studied. The work was targeted towards removal of Iron (Fe) and Chromium (Cr), two very common contaminant in urban as well as rural ground water. These are also found in industrial spent waters. the efficiency of the biofiltration process for heavy metals removal have been critically analysed. In a proof-of-concept study, a laboratory-scale closed biofilter system employing the trickle bed process was operated to remove Iron (Fe) and Chromium (Cr) from a synthetic waste water sample at a load of 1000mg/L of the heavy metal. Gravel, citrus peels and spent tea leaves after proper pre-treatment was used as filter media. Depth profile analysis of the filter bed showed the reduction of a steep gradient of Iron and Chromium from the top layer to the bottom layer of filter media in the biofilter. Iron and Chromium level at the bottom of the biofilter decreased over 85% over a period of 6-8 hours of experiment. With these observations we have scaled up the process from a 0.050 L to 15.0 L operating volume. The results were consistent.

CHM09-Emperical modeling of growth parameters in cellulosimicrobium cellulans during heavy metal tolerance

Nikhil Kumar Pipil, Sayan Chatterjee, Ram Singh Purty University School of Biotechnology, Guru Gobind Singh Indraprastha

University, New Delhi 110078. Abstract

In the present work we have studied the growth kinetics of Cellulosimicrobium cellunans under different metal stress. The strain used was Gram positive and non pathogenic. Metal studied were Fe, Zn, Pb, Cu, Cd, and Ni. Growth curve of Cellulosimicrobium cellunans was studied under different concentration of these metals. In the second part of our investigation we tried to established growth equation which can define growth curve of Cellulosimicrobium cellunans. The three parameters µm, λ, Xm majorly contribute to growth equation. The changes in these parameters affect the location and duration of exponential or log phase t. Thus, we have chosen these factors primarily to model our system. In each case we have observed little deviation from the predicted equation at the maximum error percentage below 10% (α< = 10) R2<0.8. Next we have tried to model the cumulative effect of these metals simultaneously but our model has failed to reach an appreciable correlation with the experimental data set. In this case we may assume that more factors like mole fraction or partial molar volume of metal solution may have contributed to the growth profile.

Abstract

In recent years, the surface water quality has been observed deteriorating due to industrial activities and pollution in the Punjab state. Evaluation of surface water quality is an important issue to assure from its safe and stable use. However, describing quality conditions is generally difficult considering spatial variability of pollutants and a wide range of indicators like biological, physical and chemical substances which can be measured. This paper includes the study of surface water quality parameters in the northern Punjab region. Samples from different sources across northern Punjab were analysed for pH, TDS, TSS, turbidity, DO, chloride content, iron content and hardness of surface water. The pH, TDS, TSS, turbidity, DO, chloride content, iron content and hardness were found in the range of 6.7-8.7, 1358.00-1430.60 mg/l, 135.10-141.21 mg/l, 0.001-0.62 NTU, 0.96-7.80 mg/l, 0.80-15.56 mg/l, 0.01-0.02 mg/l and 1.2-13.9 mg/l respectively. The obtained results were compared with the acceptance limits as given by Indian standard code IS: 10500-2012. The high values of water quality parameters obtained as a result of this study indicates the level of pollution of the different sources of surface water of northern Punjab. At the end the obtained results were critically examined and suggestions were made for better management of surface water resources.

Department of Chemical Engineering, Lovely Professional University, Jalandhar, Phagwara, Punjab,

Abstract Around two billion tonnes of alkaline residues are produced globally every year by various industries steel plants, alumina refining, coal-fired power generation, and chemical industries with a total production estimate of 90 billion tonnes since industrialization. These wastes are frequently stored in waste piles or landfills, and can be an environmental hazard if allowed to generate in open space or if rainwater infiltrates the wastes. Even throwing out the alkaline waste (8.5-10) to the water body can bring out sever physiological disturbances to most of the aquatic animals like in fish and other water bodies inhibiting the rate of ammonia excretion which increases the level of accumulation and toxicity. Finally, research needs are identified that could better understand the biogeochemistry of highly alkaline systems in order to develop predictable passive remediation and metal recovery technologies. Many chemical industries produce alkaline waste which is problematic to manage and convert it into neutral of pH 7. It is challenging for industries to manage the alkaline waste or to recover useful material from mother liquid pH 10. In this paper we replace the salt by acid for the isolation of 3, 3 Dichlorobenzidine (3, 3 DCB) products and make the waste mother liquid to acidic of nearly pH 2. So, in this work isolation process is carried out by replacing salt by HCl and is tuned pH 2 is achieved. The acquired pH was found to contain 30% of sulphuric acid and 60% of HCl. The processed slurry was undergone next phase separation operation using a multiple effect evaporator followed by Azeotropic distillation process. Here in this zone acid recovered from the mother liquor was found to touch (60%. It’s found to be a Nobel way that mother liquor is recovered again for making the salient product that meet the need of the relevant industries.

Department of Chemical Engineering, Lovely Professional University, Jalandhar, Phagwara, Punjab, 144411

Abstract In recent years, organic photovoltaic cells (OPVs) have emerged into an advanced technology to cater energy requirement of the world. Unlike the traditional solar cells, organic photovoltaic are made of compounds (conductive organic polymer or small organic molecules) that are dissolved in ink and can be printed and moulded using simple techniques. Organic photovoltaic are made of electron donor and electron acceptor materials. The main principle in this study is that the material used for absorption and charge transportation is mainly based on the element carbon and not on the metals. It uses the mixture of polymer which is set up at different repeating units that appears in the form chain and also fullerenes. These compounds are mixed and dissolved to become an ink and they can be printed with simple printing techniques as flexible substances. The result is a low weight, flexible, semi-transparent film. This active thin layer absorbs energy of the sun and is extremely affective. It is just 2 µm. Just 1Kg of basic polymer ink can print a solar cell of football field. It is like a plastic foil. They are very well suited for membrane architecture. It can also reduce the installation charges as it can be used as an outer layer for the buildings. With printing process, the solar cells can change its shape and design very easily so that it can be used as per the need of the building. Thus, a building designed by sustainable principles can produce all the power it needs.

CHM15-Grassoline-a bio-fuel from grass

Raushan Kumar Karn, Swapna Rekha Panda Department of Chemical Engineering, Lovely Professional University,

Jalandhar, Phagwara, Punjab, 144411 Abstract In the quest of more sustainable energy resources, techniques on extracting bio fuels are under research in developing stage. This poster is devoted with a case study followed by thorough review of literature work based on bio-fuels from grass till date. Switch grass a native perennial species of north east countries which is an attractive source of green fuel consisting 70% of organic cellulose, a complex carbohydrate. The poster describes the production of bio-fuel in two generations modes: first, undergoing a series of chemical conversions consisting disintegration and treatments, “decane” which is used as a primary ingredient in gasoline and jet fuels was produced. In order to improve its biodegradability, it is first pre-treated then bacteria are added to convert sugars present in the grass into lactic acid and its derivatives. But, they report the process wasn’t environment friendly and economical, although the latest update of their part is under research. Whereas second generation bio-fuel limits these drawbacks, containing cellulosic-ethanol produced from the feedstock of switchgrass by the breakdown of cellulose and ethanol produced. Since the process involves the very initial step of deconstructing the grass biomass into small molecules, till date there is no proper approach for the maximum possible conversion. Although, this poster brings out challenging issues, still then major advantage lies behind the fact that conversion of the cellulosic material into fuel will lead to (i) no shortage of feedstock (ii) open up a pathway for generation of green fuel from abundantly available green grass as a rich source of fuel to meet world’s supply-energy chain. As per the Argonne National Laboratory, conversion of switch grass to cellulose ethanol corresponds to 10 times the energy output per one unit of energy input. This source of energy anticipates the highest side of energy as that can be obtained using corn as a source of energy stock. Mostly, this poster overviews a new approach to rigorous, extended, advanced and intense research for the ease of conversion of green fuel/bio-fuel/gasoline from a grass.

It is also reported that using discrete ribs over the absorber plate in place of continuous ribs more heat transfer can be achieved. The present paper gives us the details of various artificial roughness provided over the absorber plate to increase turbulence thereby increasing its performance. This paper gives a brief overview of various researches done on Single as well as Double pass solar air heaters in terms of its Thermal and Thermohydraulic efficiencies along with its Nusselt Number and Friction Factor enhancement.

Abstract

Recently the prices of the petro-chemicals and electricity based products are increasing day by day. Moreover, conventional sources are limited and continuously depleting. So, it is directly affecting the economy of the country due to the high consumption rate by high consumers in different sectors namely domestic, agricultural, industrial and commercial. Energy crisis is very serious and challenging issue in the Indian scenario. We have to look for new resources for energy production. Although there are various forms of Non-conventional energy sources such as wind, solar, geothermal, and biomass etc are known. Which are clean and eco-friendly but this study is majorly focused on biomass energy because the Indian economy is basically village economy based on agriculture/agricultural products. Every year million tons of un-useful biomass generates from agricultural land, which causes problem in storage and as well as creates air pollution on open burning. So, we need to look for technology which can store them for efficient use. So, this review closely focuses on use biomass based renewable energy techniques for the energy production and as well as storage.

Abstract In the present work, low-cost ceramic membranes are prepared by paste casting method using kaolin and fly ash along with other additives such as sodium metasilicate, boric acid and calcium carbonate. The effect of raw materials composition (i.e., kaolin–fly ash ratio, K:F) on the membrane properties (strength, porosity, pore size, permeability, etc) was studied. The raw materials mixture was subjected to TGA and the prepared membranes were characterized by SEM, XRD, liquid permeation, mechanical strength and chemical stability tests. The TGA of the mixture indicated no weight loss above the chosen sintering temperature of 900°C. The SEM analysis indicated that the membranes were free of defects and had homogeneous surface structure with evenly distributed pores of similar sizes. The XRD analysis identified crystalline phases of different minerals that contributed for the strength. The membrane porosity was evaluated based on the gravimetric method. Addition of 15% CaCO3 provided sufficient porosity to all membranes (25–46%). It increased with an increase in the kaolin content (K:F) owing to the dehydroxylation of kaolin to metakaolin during the sintering process. On the other hand, the pore size (estimated by liquid permeation test) decreased with the K:F ratio, because of the smaller particle size of kaolin in comparison with fly ash. A K/F ratio of 0:1 resulted in the largest average pore size (2.3 μm) and the ratio of 1:0 yielded the lowest pore size (0.73 μm). The chemical stability and mechanical strength increased with increase in the K/F ratio because of formation of mullite, anorthite, metakaolinite, quartz and nepheline phases as evidenced from XRD. All membranes showed superior stability in basic conditions (pH ~ 13) while the membranes prepared using K/F ≥ 1 had permissible weight loss (< 4%) in acidic conditions (pH ~ 1.5). Considering all the membrane properties and cost of raw materials, a K/F ratio of 2:1 was found to be optimum among all the prepared membranes. The suitability of this optimized membrane (K/F = 2) was also tested in the microfiltration of natural organic matter, and the membrane showed excellent filtration performance with a separation efficiency of more than 92%. Although, the permeate flux declined steadily with time, it was recovered by membrane regeneration. Fitting of different models to the flux data indicated the formation of a cake layer because of concentration polarisation at the membrane surface during

232

dead-end filtration. The permeate quality at low transmembrane pressure (1.03 bar) was found to be acceptable for drinking.

Chetan Bhagat, Kashish Mehta

School of Chemical Engineering & Physical Sciences Lovely Professional University, Phagwara Punjab-144411

Abstract Rapid industrialisation and hike in fuel prices has led to a growing concern for the development of alternative fuel from renewable sources. Biodiesel is one of the promising biofuels as a replacement to petroleum diesel in the future. The heterogeneous catalyst development especially from calcium has gained much popularity due to their corresponding high catalytic activity in the transesterification of oil. The present study reports the synthesis of a strontium functionalised calcium oxide (Sr/CaO) catalyst via wet impregnation method that can be used for biodiesel production from waste cooking oil via transesterification reaction. The optimal yield of 95.3 % was obtained at the following reaction conditions: 1.5 % (w/v) catalyst dose, 9:1 methanol to oil molar ratio, 60 °C reaction temperature and 180 min reaction time. The properties of obtained biodiesel were within the specifications of ASTM 6751 biodiesel standards.

PTE01-Petroleum engineering: Application of remotely operated vehicles (ROV) in marine seismic surveys

Sonu Singh, Adityam Dutta Department of Petroleum Engineering

School of Chemical Engineering and Physical Sciences Lovely Professional University, Punjab, INDIA

Abstract

The utilization of ROVs in the Oil and Gas industry has fulfilled with a wide-ranging purpose in the Exploration and Production game. Their expertise is greatly exercised particularly in the field of exploring the deeper depths of underwater, sea mapping, routine checkup of underlying facilities etc. However, use of these ROVs are now moving towards new horizons of innovations, especially in the field of acquiring seismic waves during offshore operations. The new approach of executing marine seismic surveys is aimed at employing substantial utilization of ROVs. The concept aims at an arrangement designed as such that the hydrophones will be attached to the towed ROV that shall traverse all the way to the seafloor. Seismic or acoustic waves produced from the source, i.e., the air gun, will be attached to the surveying vessel, as done in the conventional offshore seismic exploration activities. The reflected acoustic waves will be identified by the hydrophones, which are towed with the ROV at the seabed. The proposed approach for employing ROVs to perform marine seismic surveys can prove beneficial in interpreting raw seismic data as there seems to be a favorable possibility of separating the seismic signals and its associated noise. Firing of the air gun produces acoustic waves that oscillate in the water, creating waves which interfere with the initial impulse, thereby making interpretation difficult. This activity of bubble effect can be negated by using the proposed ROV method. Application of the proposed ROV scheme can contribute towards neglecting and removing the noise, thus saving the time of the raw data interpretation and coming up with better seismic interpretation.

Abstract

As the proven reserves of Oil and Gas (O&G) are nearing towards its maturity phase, the production from the fields is progressively shrinking. India’s economic demands for crude oil import, especially the O&G industry has been greatly having its dependence of crude oil on the foreign nations, especially the OPEC (Organisation of Petroleum Exploration Countries) nations. However, there lies a huge potential for the existing fields of India to produce incremental Oil and Gas beyond their current recovery scenarios. Enhanced Oil Recovery (EOR) is such a technique, which employs combination of technologies that deliver increased volumes of crude oil and gas that were earlier assumed to be beyond the scope of recovery. EOR schemes engaged at various brown fields aims at displacing the immovable oil that were so far not achievable through the conventional methods of secondary recovery. This is greatly due to the significant pressure depletion in the reservoir that follows because of continuous hydrocarbon recovery at varying recovery rates. Apart from the previous fact, crude oil is a good blend of hydrocarbon molecules ranging from C1 to C40+. This paper aims to provide an provide the impact of Enhanced recovery implementation in Indian Oil field. The work bridges the gap in comprehending the EOR techniques developed so far, the various implementations adopted by the Indian Oil Exploration and Production (E&P) companies. The paper also provides a perception on how well can India adhere to the recently adopted policies of Enhanced Recovery screening guidelines in subsiding the reliance of foreign crude imports to achieve a strong energy establishment in the world.

School of Chemical Engineering and Physical Sciences, Lovely Professional University, Phagwara, Punjab, India

Abstract

Reservoir performance prediction is an important aspect of oil and gas field development planning and reserves estimation that reflects future reservoir behavior. Reservoir production success is dependent on accurate exemplification of reservoir rock properties, reservoir fluid properties, rock-fluid properties, and reservoir flow performance. Petroleum engineers must have knowledge about reservoir characteristics, production operation optimization and, more importantly, to develop an analytical model that will adequately describe the physical processes occurring in the reservoir. Reservoir performance prediction based on the material balance equation described by several authors such as Muskat, Craft and Hawkins, Tarner, Havlena & Odeh, Tracy and Schilthuis. This paper compares the estimation of reserves using dynamic simulations in MBAL software and predictive physical equilibrium method after matching the history of both of these models. The results of this paper demonstrate the functionality of MBAL in terms of history matching and performance prediction. The purpose of this paper is to establish the water drive reservoir model and algorithms for each technique are presented and validated with an example. PVT analysis, collecting well data for production and quality checks, quality checking based on determining discrepancies between data and physical reality with the help of correlations. Also, this paper shows the history of the original oil matching the place and size of the aquifer. The conclusions obtained from the various plots between different parameters indicate the history matching data, simulation results, and future performance of the reservoir system and observations of these results that represent the results of similar simulations and future predicted plots.

Abstract In this paper, we have purposed and analyzed a delayed mathematical model of Forestry Resource Biomass with Industry and Export. In this model, we have studied the effect of time delay on industrial technology in the context of conservation of biomass. The existence of equilibrium points and their local stability have been discussed in the absence of time delay. In the presence of time delay, the system exhibits rich dynamics with the existence of Hopf-bifurcation, period-doubling phenomenon and chaos when parameter delay passes through a sequence of intervals. Explicit results are also derived for finding stability and direction of the bifurcating periodic solution using normal form theory and central manifold theorem. Finally, all analytical findings are validated using numerical simulation.

Abstract A graph pebbling is a combinatorial game played over a fixed graph and a pebbling move is the method of removing two pebbles from one endpoint and sets one pebble at the other endpoint, while the remaining pebble is dropped. It was first developed by Lagarias, Saks, and Chung used it as an alternative test to a scientific problem in additive number theory. Pebbling theory is used as a network optimization model for the transportation of consumable resources in which some of it is used during the travel. Oil tankers may use up some of the oil in transports during its transit. The pebbles can be considered as oil barrels. The rubbling number of a graph is the smallest number needed to guarantee that any vertex is reachable from any pebble distribution of pebbles. A vertex is reachable if a pebble can be placed using pebbling or rubbling moves. In this paper a comprehensive review of almost all the existing works in pebbling and rubbling is carried out and connections between the graphs are also presented.

Abstract A revised model is used to study Rayleigh-Bénard convection of a viscoelastic Oldroyd-B nanofluid layer with more realistic boundary condition i.e. the flux of nanoparticle volume fraction is considered to be zero on the boundaries. Combined behaviors of Brownian motion and thermophoresis due to the presence of nanoparticles are emphasized. It is found that for the case of Oldroyd-B nanofluids oscillatory convection sets in before stationary convection. For stationary convection viscoelastic nanofluid acts just as a Newtonian nanofluid due to the absence of viscoelastic parameters in the expression of thermal Rayleigh number. Interestingly, oscillatory motions come into existence due to viscoelasticity of the Oldroyd-B fluid. Further, the stress relaxation parameter (λ1) hastens the onset of oscillatory convection whereas the strain retardation parameter (λ2) has the effect of postponing the same. The effect of various non-dimensional parameters on the onset of convection has been investigated using the software Mathematica. The critical frequency of oscillations as a function of strain retardation parameter for various values of non-dimensional parameters is computed numerically and its effect on the stability of the system is depicted graphically.

Abstract In this paper, we analyze a cosmological situation proposing a variation law in which the deceleration parameter is assumed to be a simple linear function of

Hubble’s parameter, which yields scale factor 𝑎 as 𝑎=𝑒1

𝛽√2𝛽𝑡 + 𝑘(where 𝛽,𝑘 are

constants). We have gotten the cosmological models in which the Universe begins from a non-solitary state and grows exponentially with infinite time t till late occasions. The deceleration parameter in the model is observed to be time subordinate. The deceleration parameter in the model is found to be time dependent. It is seen that this parameter shows a transition from initial decelerating phase to the present accelerating phase of expansion and supplies the largest value and the fastest rate at which the universe is expanding. Same is also observed by the researchers. The cosmological term Λ approaches to zero as t tends to infinite also shown by recent observations.

Abstract This paper deals with the establishment of an energy plant in a specific area under the consideration of several socio-economic factors. There is a numerous number of conditions and factors to install an energy plant in a location. These factors include environmental conditions, social status, availability of river and dams, availability of open grass field and many more. Every factor is responsible for a specific energy plant to be established in a specific location such that the demand is completely fulfilled without harming the socio-economic status and natural environment of that location. In this respect, this study considers an intuitionistic fuzzy approach to identify the relation between the set of locations and the set of factors. In a similar manner, the relation between set of factors and set of energy resources is established. Based on these two relations, Sanchez's approach is utilized to obtain the most suitable location for the installation of a particular energy power plant. The mathematical model and an efficient algorithm are developed. The model is validated with numerical experiments and graphical representation.

E-mail: rimmy035@gmail.com

Abstract The present work is concerned with the transient analysis of the Two-dimensional state markovian queueing model with reneging and multiple vacations. Arriving customers renege according to negative exponential distribution. Transient analysis is more appropriate in understanding the behavior of the system. Two dimensions represent respectively the number of arrivals at the system and departure from the system at a given time. To start with, the system has an arbitrary number of customers say (“i”) units at the time “t=0” and the state of the system is given by (n,k) where ‘n’ is the number of arrivals and ‘k’ is the number of the departures upto time ‘t’. Allowing servers to take vacations makes the queueing model more realistic in studying the waiting time system appropriately. For example: in ticket counter for reservations, in communication for messages to be delivered, patients forming a queue to have appointments before the clinic opens or arrival of the doctor and so on. The solution for this model is obtained recursively with the help of Laplace transformations and results are calculated without involving complex functions.

Abstract This paper discusses a two-state multiserver retrial queueing system with balking. Entering customer is admitted to join any idle server and receive his service immediately. On the other hand, if all the servers are busy, then the entering customer joins the orbit or balks from the system. Arrival of primary calls and repetition of repeating calls both follow Poisson distribution. Service times of each server follow exponential distribution. Time dependent probabilities of exact number of arrivals and exact number of departures at when all, some or none servers are busy are obtained by solving the difference differential equations recursively. Results for particular cases are also discussed.

Abstract Let 𝐺 = (𝑉(𝐺), 𝐸(𝐺)) be a graph on 𝑛 vertices. A bijection 𝑓: 𝑉(𝐺) → {1,2, … , 𝑛} is called prime labeling if for each edge 𝑒 = 𝑢𝑣, 𝐺𝐶𝐷{𝑓(𝑢), 𝑓(𝑣)} = 1. A graph which permits prime labeling is called a prime graph. A graph G is a prime distance graph if there is an injective function 𝑔 ∶ 𝑉 (𝐺) → 𝑍 such that for any two vertices 𝑠 and 𝑡 which are adjacent, the integer |𝑔(𝑠) − 𝑔(𝑡)| is a prime number and 𝑔 is called a prime distance labeling of 𝐺. So 𝐺 is a prime distance graph if and only if there exists a prime distance labeling of 𝐺. In this paper, we obtain the prime labelling and prime distance labelling of certain classes of graphs.

Abstract Queueing networks are current area of great research and application interest, in view of their increased applicability in-modeling manufacturing facilities and computer/communication networks, production and assembly lines, hospitals, transport systems, banks and so forth. The present paper develops and analyses a two-node tandem queueing model with feedback. Such type of model finds its application in many fields, e.g. telecommunication, inventory, hospitals, traffic control and so on. For example, in hospitals, a patient first visits the doctor and goes through a series of examinations, after which he revisits the doctor for medication. The inter-arrival time is exponentially distributed, whereas the service rate for each stage is dependent on the number of customers in the respective queues and thus follows non-homogeneous Poisson process. After constructing the difference –differential equations, and using probability generating function technique, we have obtained the joint probability distribution for queue size. Some key performance measures such as the average number of customers in queue, variance of the number of customers in each queue, average waiting time in each queue are computed.

Abstract In the present paper Hyperbolic B-Spline based Differential Quadrature Method is proposed to solve the Non-Linear Fisher’s Reaction-Diffusion Equation numerically. By using the proposed method, the governing partial differential equation is converted into a system of ordinary differential equations and then Runge-Kutta scheme is implemented. Accuracy of the proposed method is checked by using discrete root mean square norm (𝐿2) andmaximum error norm(𝐿∞). A comparison has been made of proposed numerical scheme with the previous numerical schemes already present in the literature review. The noteworthy point here is that the proposed numerical scheme is easy to use and indicates some better results.

Abstract Yellow fever is a vector borne disease caused by infected mosquitoes. It is a life-threatening disease which is endemic in many parts of the world. Continuous efforts to eradicate and minimize the disease burden are being done using theoretical and statistical models. In this paper, we have considered a mathematical model for transmission of yellow fever for human and mosquito populations. Vaccination and insect repellent are introduced in the model as control measures. Stability analysis for disease free equilibrium is being done. The threshold parameter, that is, reproduction number is calculated which will predict the direction in which disease can be eliminated.

MTH026-Impact of water toxicity and acidity on dynamics of prey-predator aquatic populations: A mathematical model

Preety Kalra1, Shreya1* 1Department of Mathematics, Lovely Professional University, Phagwara,

Punjab E-mail: shreyatangri25@gmail.com

Abstract Escalation in pollution and contamination of the aquatic bodies is one of the alarming issues in recent times. Discharge of agricultural and industrial effluents into the water bodies is deteriorating the quality of water. Further, acid rain and pollutants washed off from land directly into water bodies lead to an increase in acidity of water. These phenomena cause a decline in dissolved oxygen level of water, thus, threatening the survival of aquatic organisms. A non-linear mathematical model has been proposed to investigate the effect of toxicity and acidity on a prey-predator system wherein the predator is assumed to be completely dependent on prey for food. Also, it is assumed that rise in water acidity and toxicity develops impairments and infection in the lower level of food chain i.e. prey, which has indirect detrimental consequences for the growth and survival of the higher level of food chain i.e. predator due to consumption of prey by predator in the feeding process. Stability analysis of the model has been carried out and stability conditions have been derived taking into account all parameters of the proposed model. Numerical simulations are performed using MATLAB to support the analytical results obtained.

Abstract Road bumps are one of the traffic calming tools installed on the roads to control the speed of the vehicles, to avoid accidents and help pedestrians to cross the road. Road bumps should be set up keeping in the mind the various factors such as location type, traffic type, population density, and others. Work was done on the various types of road bumps mainly conical-shaped road bumps and usage of the Fourier series which is effective for periodic shaped bumps. In this paper, we are going to use the Laplace transform which is effective not only on the periodic type of the road bumps but also on the complex structures of road bumps and will study it on the hollow rectangular shaped road bumps. We will find the parameters especially the effective distance between the two consecutive road bumps and displacement caused to the vehicle which would help in the designing of the road bumps so that vehicle could move safely over the bumps and least damage could be caused to it and travelers inside it.

Abstract Time series display irregular patterns and self-similar microstructures usually termed as fractals over a period of time, depending on several factors like climate, season, market fluctuations, growth cycles etc. Various methods are developed in mathematical modeling to investigate such trends in the time series. Black carbon is one of the major air pollutants released during several mining activities having dangerous effect on climate and human health. In this paper we aim to study the behavioral pattern and trends in the time series of black carbon concentration over the three major coal mines of India namely Raniganj, Jharia and Bokaro considering a long term time series data of past 38 years using regression and fractal dimensional analysis of black carbon between the major coal mines with the help statistical tools like Hurst exponent, predictability index and trend percent. In this comparative study it is observed that the time series display anti persistent behavior with positive and large variation then the past time. The results and comparisons obtained will be helpful in studying the behavior and trends in the concentration of black carbon over the coal mines regions. The significance of the study will be helpful to gather the interest of researcher’s, NGO’s and government towards the black carbon concentration over the coal mines so that preventive measures and new policies be framed to keep a check on black carbon concentration in these areas.

Abstract Let 𝐺 (𝑉, 𝐸) be a graph. A set 𝑆 ⊆ 𝑉 is said to be a power dominating set (PDS) if every vertex 𝑢 ∈ 𝑉 − 𝑆 is observed by certain vertices in 𝑆 by the following rules: (a) if a vertex 𝑣 in 𝐺 is in PDS, then it dominates itself and all the adjacent vertices of 𝑣 and (b) if an observed vertex 𝑣 in 𝐺 has 𝑘 > 1 adjacent vertices and if 𝑘 − 1 of these vertices are already observed, then the remaining one non-observed vertex is also observed by 𝑣 in 𝐺. A power dominating set 𝑆 ⊆ 𝑉 in 𝐺 (𝑉, 𝐸) is said to be an equitable power dominating set (EPDS), if for every vertex 𝑣 ∈ 𝑉 − 𝑆 there exists an adjacent vertex 𝑢 ∈𝑆 such that the difference between the degree of 𝑢 and degree of 𝑣 is less than or equal to 1, i.e., |𝑑(𝑢) − 𝑑(𝑣)| ≤ 1. The minimum cardinality of an EPDS of 𝐺 is called the equitable power domination number of 𝐺, denoted by 𝛾𝑒𝑝𝑑(𝐺). The vertices and edges of G are called elements. Two elements of G are neighbors if they are either incident or adjacent in 𝐺. The total graph 𝑇(𝐺) has vertex set 𝑉(𝐺) ∪ 𝐸( 𝐺) and two vertices of 𝑇(𝐺) are adjacent whenever they are neighbors in 𝐺. In this paper, we obtain the equitable power domination number of the total graph of certain graphs.

Abstract This article presents a short and concise survey on prime cordial and divisor cordial labeling of graphs. Sundaram et al. introduced the notion of prime cordial labeling. A prime cordial labeling of a graph 𝐺(𝑉, 𝐸) is a bijective function 𝑓: 𝑉(𝐺) → {1, 2, . . . , |𝑉|} such that if each edge 𝑥𝑦 is assigned the label 1 if 𝑔𝑐𝑑(𝑓(𝑥), 𝑓(𝑦)) = 1 and 0 if 𝑔𝑐𝑑(𝑓(𝑥), 𝑓(𝑦)) > 1, then the number of edges labeled with 0 and the number of edges labeled with 1 differ by at most 1. Further, Varatharajan et al. defined a divisor cordial labeling of a graph 𝐺 as a bijection 𝑔: 𝑉(𝐺) → {1, 2, . . . , |𝑉|} such that an edge 𝑠𝑡 is assigned the label 1 if one 𝑔(𝑠) or 𝑔(𝑡) divides the other and 0 otherwise, then the number of edges labeled with 0 and the number of edges labeled with 1 differ by at most 1. We call G a divisor cordial graph if it admits a divisor cordial labeling. This article stands divided into five sections. The first and fifth sections are reserved respectively for introduction and some important references. The second section deals with the prime cordial labeling of certain classes of graphs wherein some important known results have been recalled. The third section deals with the divisor cordial labeling of graphs in which a few known results of high interest have been outlined. In the fourth section we highlight certain conjectures and open problems in respect of the above mentioned labelings that still remain unsolved.

Abstract An assignment of integers to the vertices of a graph 𝐺(𝑉, 𝐸) on 𝑛 vertices subject to certain constraints is called a vertex labeling. A set 𝑆 be a finite and non-empty subset of positive integers. Then, the divisor graph 𝐺(𝑆) of 𝑆 has 𝑆 as its vertex set and vertices 𝑥 and 𝑦 are adjacent if and only if either 𝑥|𝑦 or 𝑦|𝑥. A graph 𝐺 is a divisor graph if 𝐺 ≅ 𝐺(𝑆) for some finite non-empty set 𝑆 of positive integers. Hence, if 𝐺 is a divisor graph, then there exists an injective function 𝑔 ∶ 𝑉 (𝐺) → 𝑁 (the set of all natural numbers), called a divisor labeling of 𝐺, such that 𝐺 ≅ 𝐺(𝑓(𝑉 (𝐺))). In this paper, we investigate the divisor labeling of certain classes of graphs.

Abstract This article presents a short and concise survey on prime graphs. Let 𝐺 (𝑉, 𝐸) be a graph. An assignment of integers to the vertices or edges or to both of 𝐺 subject to certain constraints is called a graph labeling. The notion of prime labeling was originated by Entringer and considered in a paper by Tout, Dabboucy, and Howalla. A bijection 𝑓: 𝑉(𝐺) → {1, 2, 3, … , |𝑉|} is called a prime labeling of 𝐺 if for each edge 𝑒 = 𝑠𝑡, GCD(𝑓(𝑠), 𝑓(𝑡)) = 1, where GCD denotes the greatest common divisor. We call 𝐺 a prime graph if it admits a prime labeling. This article stands divided into six sections. The first and sixth sections are reserved respectively for introduction and some important references. Sections 2, 3, and 4, respectively deal with the prime labeling of certain classes of graphs such as trees, join and product graphs, wheel related graphs etc. wherein some known results of high importance have been recalled. The fifth section deals with the enumeration of conjectures and open problems in respect of prime labeling that still remain unsolved.

Abstract Random numbers are largely needed in digital world for innumerable processes. Some of the major fields like Cryptography, Simulation & Modelling, Numerical analysis etc. use random numbers often. Various random number generating algorithms are available in the category of Pseudo random number generators, some of these pass the statistical tests for randomness and possess desired properties. In this paper an attempt has been made to generate pseudo random numbers by combining linear congruential method with low discrepancy sequence , both have their own strengths and weaknesses, the proposed method attempts to utilize strengths of both and reduce the weakness and produce a new strong pseudo random number generator with good statistical properties. The generated algorithm can be used in evaluation of higher dimensional integrals using Monte Carlo methods. This would help in overcoming some of the difficulties like error bounds calculation in evaluation of these integrals.

Abstract

Let ),( EVG be a graph. A subset VS is a dominating set of G if every vertex in SV − has at least one neighbor in S . A subset VS is a power dominating set of ),( EVG if all the vertices of V can be observed recursively

by the following rules: (i) all vertices in SN are observed initially and (ii) if an observed vertex u has all its neighbors observed except one non-observed neighbor v , then v is observed (by u ). We then say that S power dominates the vertices of .G On the other hand, a dominator coloring assigns a proper coloring to the vertices and requires every vertex to dominate a color class consisting of all the vertices with the same color. Motivated by these two concepts the notion of power dominator coloring of G has been considered which is a proper coloring of G with every vertex of G power dominates at least one color class. The minimum cardinality of such color classes is defined as the power dominator chromatic number of 𝐺, denoted by 𝜒𝑝𝑑(𝐺). The neighborhood corona of 𝐺1 and 𝐺2, denoted 𝐺1 ⋆ 𝐺2 is the graph obtained by taking one copy of 𝐺1 and |𝑉(𝐺1)| copies of 𝐺2, and joining the neighbours of the 𝑖th vertex of 𝐺1 to every vertex in the 𝑖th copy of 𝐺2. In this paper, we obtain the dominator and power dominator chromatic number of the neighborhood corona of some families of graphs. We also compare the dominator chromatic number with the power dominator chromatic number of different coronas of graphs.

Abstract This article presents a short survey on 3-equitable and divisor 3-equitable labeling of graphs. For any graph 𝐺(𝑉, 𝐸) and 𝑘 > 0, assign vertex labels from {0, 1, . . ., 𝑘 − 1} so that when the edge labels induced by the absolute value of the difference of the vertex labels, the number of vertices labeled with 𝑖 and the number of vertices labeled with 𝑗 differ by at most one and the number of edges labeled with 𝑖 and the number of edges labeled with 𝑗 differ by at most one. We call a graph with such an assignment of labels k-equitable. When 𝑘 = 3, it becomes a 3-equitable labeling. In 2019, Sweta Srivastav and Sangeeta Gupta introduced the notion of divisor 3-equitable labeling of graphs. The bijection 𝑓: 𝑉(𝐺) → {1, 2, … , 𝑛} induces a function 𝑓′: 𝐸(𝐺) → {0, 1, 2} defined by for each edge 𝑒 = 𝑥𝑦, (i) 𝑓’(𝑒) = 1 if 𝑓(𝑥)|𝑓(𝑦) or 𝑓(𝑦)|𝑓(𝑥), (ii) 𝑓’(𝑒) = 2 if 𝑓(𝑥)/𝑓(𝑦) = 2 or 𝑓(𝑦)/𝑓(𝑥) = 2, and (iii) 𝑓’(𝑒) = 0 otherwise such that |𝑒𝑓′(𝑖) − 𝑒𝑓′(𝑗)| ≤ 1 for all 0 ≤ 𝑖, 𝑗 ≤ 2. A graph which admits a divisor 3-equitable labeling is called a divisor 3-equitable graph. This article stands divided into five sections. The first and fifth sections are reserved respectively for introduction and some important references. The second section deals with the 3-equitable labeling of graphs wherein some important known results have been recalled. The third section deals with the divisor 3-equitable labeling of graphs wherein a few known results have been outlined. In the fourth section we highlight certain conjectures and open problems in respect of the above mentioned labeling that still remain unsolved.

Abstract In survey sampling, it is a very common practice to make use of auxiliary information provided by the auxiliary variables to improve the precision of the estimators. Improved estimators can be developed by using auxiliary information at the estimation stage in order to estimate the population mean. In this paper, modified class of product type estimators for estimation of population mean using auxiliary variable have been proposed. Relative bias and relative mean squared errors of the proposed estimators have been derived upto order O (n-1) and O (n-2) respectively and their efficiencies have been compared with the conventional product estimator and the estimators proposed by Robson (1957), Singh (1989), Dubey (1993) and Sharma et al., (2007). An empirical study has also been carried out through simulation in order to demonstrate the efficiencies of the proposed estimators using two population datasets P1 and P2. The empirical study showed that proposed product type estimator 𝒕(𝟑)

E-mail: abha.duggal44@gmail.com

Abstract In recent days many industrialists are following centralized industrialization due to adequate information sharing and high profitability. But, in developing continents like South Asia or Africa most of the manufacturers and retailers are following decentralization system due to lack of investment. This paper deals with such systems where information sharing is unavailable, and each party is running their business independently. The study considers numerous retailers who face difficulties in obtaining strategic decisions due to demand uncertainty. As funding opportunity is low to the retailers, the actual probability distribution of demand is difficult to obtain, and the distribution free approach is adopted in this study to obtain the managerial decisions for the retailers. Also, lead time for retailers is controlled with suitable method. The mathematical model for a decentralized supply chain is created in this research and managerial decisions are obtained numerically with many graphical interpretations.

MTH050-The study of combined effect of delay induced by acid and toxic metal on plant population: A modelling approach

E-mail: kalra.preety@gmail.com, pankaj.kumar1@lpu.co.in

Abstract In this paper, a mathematical model is proposed to study the combined effect of acid and toxic metal on plant population growth with delay. The model is framed using the systems of non-linear delay differential equations. The five state variables considered are: concentration of acid in soil, concentration of toxic metal in soil, density of favourable resources including soil and surrounding environment, plant population density and nutrient concentration in soil. It is supposed that the rate at which the nutrient is taken up by the plant from the soil is adversely affected in the excessive availability of acid and toxic metal. It is also observed that the concentration of nutrient and the plant population density decreases due to the presence of acid and toxic metal. This effect is shown by considering the delay in the term containing utilization of favourable resources. The stability of the interior equilibrium of the system gets disturbed by the introduction of delay parameter. For the critical value of delay parameter, Hopf bifurcation is also seen. The sensitivity of model solutions for different values of model parameters is established using sensitivity analysis. The model is also verified using already existing experimental data. MATLAB code is used for simulation to support analytical results.

Abstract In this paper a different cryptographic technique is introduced by transformation of sequence of functions< 𝑓𝑛 >. Each character of the message is converted to number and then transformed to another number. This transformation is different for each character of message depending upon the position of character in the sequence. Uniqueness of transformation is that if any character appearing twice will have different encryption. Modular arithmetic is also applied to reduce big numbers to small numbers. Key 𝐾 has three components (𝑘1, 𝑘2, 𝑘3) where 𝑘1 is the key sequence,𝑘2 is key vector to increase the length of numeric cipher text and 𝑘3 is random number added to the cipher text of increased length. Algorithms for encryption and decryption has been developed with illustrative example. This process can be iterated 𝑛 number of times for encryption of data.

Abstract Evolution is a fundamental part of life of every species on earth. Evolutionary history of species can be visualized by the phylogenetic trees which in turn can be constructed with the help of dissimilarities among the DNA (de-oxy ribonucleic acid) sequences of the species. In this work, a mathematical approach based on graph theoretic concept has been used to find the distance matrices of DNA sequences of species. These matrices of order four are then used to find the dissimilarities among the biological sequences by using Eucledean distance metric. At last, an UPGMA (unweighted pair-group method using arithmetic averages) has been used to construct phylogenetic trees among the biological sequences. The mathematical approach has been implemented on the 11-real-life DNA sequences collected from the NCBI database and the published literature. In this work, two parameters of sequences namely positioning of nucleotide and stack interaction and their combined effects has been taken into account to find out dissimilarities among 11-real-life DNA sequences. Moreover, programs based on graph theoretic concept have been coded in C++ language to convert DNA sequences into distance matrices of order four in short time. The results obtained by the mathematical approach are presented in the form of phylogenetic trees which are then compared and validated with the results obtained by using existing software T-Rex for construction of phylogenetic trees among biological sequences.

E-mail: rashmiarora822@gmail.com

Abstract In modern education system, students are suffering from choosing proper stream in undergraduate courses. Due to high availability of choices, there are a significant number of streams for a specific course provided to a student. In this respect, this paper aims to develop a mathematical model for the decision making in choosing a particular stream out of several alternatives. In this research, several alternatives are given to a student and each alternative corresponds to some criterion. The student must choose an alternative under the basis of the educational background of the student. All alternatives, criterion, and weights are assigned with fuzzy membership, and non-membership function. The entire method of choosing the correct alternative is created under intuitionistic fuzzy TOPSIS method. The model is validated with proper numerical experimentation.

Abstract Agriculture is a backbone of India’s economy. Oilseeds have been playing a vital role after food grains in India’s economy in terms of area and production. From 1974-75 to 2018-19, oilseed production has shown an overall increasing trend but due to increasing population we have to import oilseed from other countries in order to mitigate the demands of our country people. In the present study, an attempt has been made to propose an autoregressive integrated moving average (ARIMA) model to forecast the oilseed production in India which will help to analyze the past and current behaviour of oilseeds production and hence provide an aid to decision-making and in planning for the future effectively and efficiently.

Abstract The existing paper analyzes the reliability of a two-unit cold standby system working in a pharmaceutical company with preventive maintenance. Initially, one unit is operative and the other is stored as a cold standby. Upon failure of an operative unit, the cold standby unit becomes operative. As variation in demand influences the production of the machine also, hence, sometimes, the system needs to be in the rest length when the wide variety of produces is in excess as in contrast to those demanded. When the machine goes to rest, the PM/CM is carried out to make the machine ready for operation. The factor of the rest period due to less demand has additionally been taken into account for the assessment of the earnings for the system. Each unit is assumed to have an exponential distribution of the time to failure as nicely as that of the relaxation length while the distribution of restore time is taken as arbitrary. Markov processes have been used to obtain more than a few measures of the system's effectiveness. Numerical results and some graphs of a specific case are also included.

Abstract The main objective of the manufacture industry is to acquire the maximum profit by minimizing the production cost and maximization of the selling price of the different products fabricated by them. After accomplishment of the optimal value for the production cost the industry focuses on maximizing the selling price of items. However, the competitiveness and uncertainty of the market, the supplier sells their products of discrete selling prices. Therefore, their profit is fluctuated. Such situations to find the optimization of the profit is the main issue of the firm and such destruction can be mitigated with the help of fuzzy linear programming problem. In FLP coefficients of the objective function, constraint variables and the solution values are represented by fuzzy numbers. In this paper, we proposed a newly constructed triangular fuzzy numbers (TFN~𝜏1) which represent the various realistic circumstances for the selling prices of the various items of manufacturers and then TFN~𝜏2 based on TFN~𝜏1 is constructed which shows the all possible states of the profit received accordingly numerous sell prices industry might be earned. The data of “R.P.S entrepreneur Jalandhar” is taken which manufacture special types of pipe fitting items with particular sizes according to the demand in Punjab region. We constructed the general structure of the FLP to obtain all attainable bound of the optimal values using newly constructed TFNs. After that a comparative study of the optimal FLP to achieve the membership grades in all conceivable latitude.

Punjab E-mail: surenders340@gmail.com, ripudaman.17178@hotmail.com

Abstract Morphometric analysis forms the basis for planning water and soil conservation treatments in a watershed. Geospatial topology based morphometric analysis in Dholbaha watershed, located in the Kandi region of Punjab, were calculated using the IRS data of LISS IV, Cartoset-1 merged satellite data, ASTER DEM and ArcGIS-10.2 software. As per topology, Dholbaha watershed is the 5th order watershed. Out of all the 279 streams identified, 213 are of 1st order. The total stream length is 191.73 kms. The dendritic drainage pattern is found with stream frequency of 4.67 no./km2 and mean bifurcation ratio of 3.9. Both length as well as number of streams decrease with the increase in the order of streams. Topological model indicates lesser affect of geological structure on the drainage pattern of the watershed. Drainage density of watershed (3.21 km/km2) reflects the closeness of spacing in channels with permeable sub strata. Fine drainage texture (7.34 no./km) and large length of the overland flow (150 m) in watershed resulted into high peaked hydrographs and high sheet erosion in the watershed. The circularity ratio, form factor and elongation ratio of the watershed 0.412, 0.51 and 0.72, respectively indicate that watershed is

less elongated in shape, associated with medium to high relief, having moderately permeable sub-soil conditions resulting in moderate peak discharge, and moderate runoff volume resulting in high soil erosion. The watershed requires urgent conservation measures to control siltation of the reservoir. MTH071-Quantity based mathematical approach for forecasting stock index

In each quantity based index which has many fields, on that basis we have taken two types of quantity based factors, first is main quantity based factor and second is secondary quantity based factor are applied for forecasting of stock index. For forecasting, the methods are QBFTS and QBFVGs. In succession of that, fuzzifying variation of the main quantity based factors that make some relation of the fuzzy sets. This type of relation is called QBFLR. Also, arrange the QBFLRGs with the help of linguistic term, which is represented by fuzzy sets. In this mathematical approach, these terms and groups are used for calculation of difference variation of quantity based factors and weights of the quantity based factors. Finally, based on the weights of quantity based fuzzy variation appearing in the QBFVGs and QBFLRGs, opted for forecasting of Stock Index with help of Matlab programs.

MTH074-Fourier series involving A-function and Jacobi polynomial

Kamal Kishore Department of Mathematics, SCD Govt. College Ludhiana

E-mail: kamalbagnial@gmail.com

Abstract Usually we call a function ’special’ when the function belongs to the toolbox of the applied mathematician, the physicist or the engineer. They have a particular notation and a number of properties. Mathematically, special functions are functions defined on R or C and they possess not only series representations, but also integral representations. In the study of boundary value problems and special functions, Fourier series for generalized hypergeometric functions plays a vital role. Certain double Fourier series of generalized hypergeometric functions play a vital role in the improvement of the theories of boundary value problems of dimension two and special functions. In this paper, looking into the importance of Fourier series we have derived two integrals involving A-Function. Then we have used these integrals along with orthogonality of Jacobi Polynomials to find the required Fourier series.

Abstract In this paper the differential quadrature method using trigonometric B-spline basis function is applied to get numerical solution for the unsteady flow of two immiscible micro polar and Newtonian fluids through a horizontal channel. This numerical technique is not only subsequently easy to enforce but inexpensive in phrases of data complexity. The two immiscible micropolar and Newtonian fluids were taken into account as mixed partial differential equations. For fluid velocity and micro rotation regarding different fluid parameter sets, empirical outcomes are obtained. Three cases with constant periodic and decreasing pressure gradient for the interpretation of the outcomes are addressed. The effects of the admissible fluid parameters i.e. Reynolds number, ratio of viscosities, micro polarity parameter and time on fluid velocities, micro rotation and volume flow rate have been illustrated through graphs.
