Keynote Speech 3: Improvement of Fatigue Strength of Light Metals by

Mechanical Surface Treatment

Speaker: Prof. Hitoshi Soyama, Tohoku University, Japan

Time: 09:30 -10:00, Wednesday Morning, August 21, 2019



Abstract

Light metals such as aluminum alloy, magnesium alloy and titanium alloy are

attractive materials for automotive lightweight and aviation components.

However, one of weak points is the fatigue strength. One of key technologies for enhancement of

fatigue strength is mechanical surface treatments such as shot peening. Unfortunately, it is difficult to

improve the fatigue strength of the light metals by conventional shot peening, as solid collision by shot

increases surface roughness of because of the softness of the light metals. In the present Keynote

Speech, a novel peening method without shot, i.e., shotless peening, will be introduced. In the

proposed shotless peening, cavitation impacts, which are normally causes severe damage in hydraulic

machineries such as pumps, ship propellers and valves, are used to create local plastic deformations.

This peening method is named as ―cavitation shotless peening‖ or simply called as ―cavitation

peening‖. In the speech, the fundamental and the practical application of cavitation peening are

introduced with experimental data. The improvement of fatigue strength of additive manufactured

titanium alloy Ti6Al4V is also demonstrated comparing with shot peening and laser peening.

Keynote Speech 4: Design and Synthesis of New Transition Metal Chalcogenide

Superconductors

Speaker: Prof. Huixia Luo, Sun Yat-Sen University, China




Abstract

Transition-metal chalcogenides have long been of interest due to their rich

electronic band structures and physical properties. In our group, we focused

on design and synthesis of new transition metal chalcogenide superconductors via several methods

Conference Guide

(e.g. solid state method, wet chemical method, flux method, et al.). Combing experiment and theory

calculation, a series of new transition-metal chalcogenides superconductors (e.g. 2H-CuxNbSe2,

1T-Ti1-xTaxSe2, TaSe2-xTex, 2H-CuxNbSe2-xSx, Cu0.5Ir2-xMxTe4, Ir1-xMxTe2) have been

designed and synthesized. Further, their physical properties such as resistivity, critical fields,

magnetic susceptibility and heat capacity et al. were studied in detail. Finally, the superconducting

phase diagrams for new transition metal chalcogenide superconductors were made.

Keynote Speech 5: Behaviour of Cu electroplating on Mg alloys

Speaker: Prof. Ching An Huang, Chang Gung University, Taiwan, China




Abstract

Mg alloys are known to be lightweight materials for aerospace, medical,

automobile and bicycle industries. Owing to having high chemical activity,

surface treatments, such as chemical conversion, micro-arc oxidation, anodic

oxidation and electroplating, are essential for applications of Mg alloys. In general, electroplating is

difficult for Mg alloys which are easily corroded in a plating bath. In this presentation, an

eco-friendly electroplating process will be proposed through which a uniform Cu deposit can be

deposited on Mg alloys in an alkaline Cu plating bath. The electroplating process includes anodically

galvanic etching and Cu electroplating in the alkaline Cu plating bath. A protective deposit, Ni or

Cr-C deposit can be further electroplated on the Cu coated-Mg alloy to improve its corrosion and

wear resistance. The corrosion and mechanical properties of Ni/Cu- and Cr-C/Cu coated Mg alloys

were evaluated. The anodic polarization and potentiostatic etching were used to realize the corrosion

resistance of coated Mg alloys. Tensile, wear and fatigue properties of coated Mg alloys were also

studied.

Keynote Speech 6: Bi-directional translational research: how practical

applications fuel fundamental

Speaker: Dr. Bruno Wacogne, FEMTO-ST Institute, CNRS UMR 6174,

Besançon, France




Abstract

Translational research consists in translating fundamental research results as

closely as possible to patients. Researchers or institutions sometimes underestimate these

translational studies because it is thought that, although essential for setting up new investigation

tools, they do not deepen fundamental knowledge.

However, users face specific difficulties due to biological, physiological and clinical constraints. In

other words, new questions and scientific obstacles arise when research is applied to the real world.

In order to address these new challenges, reverse translational research is required. This paradigm

consists in understanding difficulties faced when accounting for the above mentioned constraints,

expressing them in terms of scientific theories and solving them by defining new prisms through

which reality is perceived.

Consequently, fundamental research is fueled by this renewed perception translational research

induces.

In this talk, we illustrate this principle with the development of what is, to the best of our knowledge,

the first fluorescence based calibration free micro pH sensor. The expressed need was to

continuously monitor some physiological pH related constants inside the human body. The main

clinical constraint was therefore the use of the sensor in a calibration free manner. We show how

fluorescence pH measurement had to be rethought and how a new physical-chemical understanding

of acid-base reactions at the sensor’s surface had to be discovered to address this constraint.

More generally and to open discussions on translational and reversed translational research, we

present how we developed bi-directional research actions between practitioners and technology

researchers in eastern France.

Keynote Speech 7: Reducing power loss in p-i-n organic light emitting diodes: an

attempt to advance towards the thermodynamic limit

Speaker: Prof. Dashan Qin, Hebei University of Technology, China




Abstract

Organic light emitting diodes (OLEDs) have been moving fast towards the

commercialization during the past decades, because of their appealing merits

such as easy fabrication, flexibility, low weight, etc. The OLEDs based on p-i-n concept have been

successfully made small- to medium-sized flat-panel displays widely used in mobile phones.

However, the TVs and lighting panel based on the modern OLED technology are still suffering from

fast aging, high cost, and image retention. Therefore, it is of great importance to improve the

performance of p-i-n OLEDs well established as the quasi-standard technology of OLED industry.

Like GaN LEDs, a good OLED must be a good diode featuring low power loss, i.e., low thermal

generation. The electro-thermal effect is a major factor leading to the degradation of OLED

especially at high luminance. For state-of-art p-i-n OLEDs, the heat is generated in emissive layer

due to its large series resistance; in addition, the heat is also created in the p-doped and n-doped

layers. At a given practical luminance, e.g., 500 cd/m2, the voltage drops over p- and n-doped

transport layers are comparable to that over emissive layer. Thus, it is worth investigating the power

loss caused by p- and n-doped transport layers. In general, there are three kinds of hole (power)

losses incurred in p-i-n OLEDs, i.e., the injection loss from ITO to p-doped layer, conduction loss

through p-doped layer, and interfacial loss from p-doped layer to electron blocking layer. It has been

demonstrated that the usage of a single p-doped layer is unable to optimize these hole losses

simultaneously. The similar case is also found for using a single n-doped transport layer.

In this speech, I will talk of the influences of the HOMO level of p-type host, p-dopant type, and

p-doping profile on the hole losses, and then point out that the combination of multi-p-doped layers

outperforms any single p-doped layers in both fluorescent and phosphorescent OLEDs. Also, I will

show the combined n-doped layers outperform single n-doped layers. Hopefully, the p- and n-doping

structures proposed here can advance OLEDs into the TV and lighting applications in a

cost-effective way.

Keynote Speech 8: Experimental study of the phase equilibria in the R-Al-Si

ternary systems (R: rare earth element) the Ho-Al-Si isothermal section at 500°C

Speaker: Prof. Anna Maria Cardinale, the University of Genova, Italy




Abstract

The Al-Si alloys, both in the as cast and after thermal treatment conditions,

have been recognized as interesting materials for the industries (eg

automotive, heat exchanger, etc). The addition of a rare earth element, at a very low concentration,

can modify the property of the alloys, improving some useful characters as low density and thermal

expansion coefficients, good casting performance and weldability, high wear resistance and

temperature strength, good corrosion resistance. All of the above leads to an increasing interest in the

study of R-Al-Si based alloys (R being a trivalent rare earth element). The knowledge of the phase

equilibria and the transformations that take place during the solidification pathway of foundry

aluminum based alloys are crucial, expecially in planning and develop new materials. The

industrially relevant R-Al-Si alloys have usually a concentration lying near the binary Al-Si eutectic

composition and mischmetal (alloy of rare earth metals, whose typical composition includes

approximately 50% Ce, 25% La and smaller small amounts of Nd and Pr) is often added.

Moreover, owing to the definition of pseudo-lanthanide it is possible to predict the behavior of an

intermetallic phase not prepared yet, when experimental data are available for the adjacent members

of this series. Taking into account the aforementioned considerations, investigations of a number of

R-Al-Si systems have been carried out by our research group.

To our best effort literature data on R-Al-Si systems isothermal sections (in the whole range of

concentrations) and liquidus projections mainly deal with the following, reported in figure 1 and

figure 2 respectively: La-Al-Si (0-33at%La), Ce-Al-Si, Pr-Al-Si, Nd-Al-Si, Sm-Al-Si and refs

therein, Eu-Al-Si, Gd-Al-Si, Al-Si-Tb and Al-Si-Dy, Ho-Al-Si (0-33 at%Ho), Er-Al-Si and Y-Al-Si

(0-33 at% Y). In this work will be presented the results obtained in the experimental study of the

whole Ho-Al-Si isothermal section at 500°C, in comparison with the R-Al-Si systems previously

studied (R: Pr, Nd, Sm, Eu, Gd, Tb ,Dy and Er as concern the isothermal sections; Pr, Nd and Sm as

concern the liquidus projections in the Al rich corner). The experimental techniques used have been

scanning electron microscopy (SEM), electron microprobe analysis (EDXS), X-ray powder

diffraction (PXRD) and differential thermal analysis (DTA).

By comparing the different ternary isothermal sections, fig.1, some points can be highlighted. All the

sections are characterized by the presence of intermediate phases with R content up to 60 at% rare

earth. The number of phases decreases on going from the light (Pr, Nd, Sm) to the heavy rare earths

(Gd, Tb, Dy, Er). Only the RAl2Si2 compounds form along the whole lanthanides series and these

phases are point compounds. At low R content the three-phase equilibrium: (Al) / (Si) / RAl2Si2,

11


Conference Guide

common to all the R-Al-Si ternary systems, occurs. Many R-Si and R-Al compounds extend in the

ternary system forming solid solutions at a constant R-content.

As the liquid projections in figure 2, the investigated systems (R= Pr, Nd, Sm) show the Al-rich

ternary eutectic equilibrium L (Al) + (Si)+ RAl2Si2 at the temperatures: Pr- 567°C, Nd- 561°C,

Sm- 567°C. Near the boundary R-Al binary systems, the primary crystallization regions, common to

these systems, are (Al), (Si), RAl2Si2 and RAlSi. Moreover, further primary crystallization regions

have been found for R= Pr and Sm (SmAl3 and Pr3Al11 respectively).

Keynote Speech 9: Printed Organic Light Emitting Diodes – Problems and

Perspectives

Speaker: Prof. Jacek Ulanski, Lodz University of Technology, Poland




Abstract

Organic electronics offers several advantages as compare with inorganic

technology, such as lightweight, large area, flexibility or conformability of

electronic devices. Additionally, if organic electronics is based on solution processable materials, it

should allow to employ cheap and energy-saving printing techniques for mass fabrication of very

broad range of electronic components. Among them printable organic light emitting diodes (OLEDs)

attract a special attention since the OLEDs fabricated by vacuum deposition technology are already

applied on large scale in displays and monitors since many years. However the technique of printing

OLEDs cannot overcome laboratory scale and in fact in most published reports, only one or two

layers in these devices are printed, while the rest are deposited by vacuum evaporation technique.

This is due to a number of serious obstacles hindering possibility of fabrication by means of solution

based techniques and with high precision multilayer OLED structures.

In this talk we will analyse the most important problems, which are still not fully solved, such as low

efficiency of OLEDs due to difficulties in employing triplet states, lack of proper printable

interlayers, allowing to facilitate injection of one sign charge carriers and to block charge carriers of

opposite sign, technical problems with producing multilayers structures, lack of conducting inks,

compatible with active organic layers, poor precision and low resolution of available printers, and

lack of flexible, transparent and highly efficient barrier materials. In the Department of Molecular

Physics of Lodz University of Technology we are involved since several years in research aiming to

solve the most critical issues related to printed organic electronics and we will present selected

12


Conference Guide

results illustrating application of new solution processable active layers exhibiting

electrophosphorescence or thermally delayed fluorescence (TADF), printable interlayers and

electrodes, as well as our approach for ink formulation and high precision printing technique. These

results will be used as a base for presentation of future research plans and perspectives for

developing technology of fully printable OLEDs.

Materials Science: Keynote Speech Session 2

Keynote Speech 10: Optical Responses of Two-Dimensional Materials –

Valleytronics and Phase Transition

Speaker: Prof. Jian Zhou, Xi’an Jiaotong University, China

Time: 14:00-14:30, Wednesday Afternoon, August 21, 2019



Abstract

In order to manipulate and tune the physical properties of a material, usually

one has to apply an external field, such as elastic and inelastic strain, electric

field, magnetic field, or light illumination. Among these strategies, the optical

field is a far field, which does not need mechanical or electrochemical contact or patterning onto

material samples. In this talk, I will discuss optical responses of low-dimensional nanoscale materials,

mainly focusing on two promising aspects, namely, valleytronics and phase transition. The close

connection between the circularly polarized light with valleytronics is initiated by the discovery of

two-dimensional transition metal dichalcogenides. Here, I will discuss some progress in our group,

such as valley polarized topological feature, valley polarized Nernst effect, and valley polarized

plasmonic behaviors, based on the same honeycomb lattice model. I will also discuss our predictions

on the modification of Gibbs free energy of two-dimensional materials under linearly polarized light

illumination, and consequent phase transition of these materials.

Keynote Speech 11: Research and Development of Novel Pressure Sensitive

Adhesives from Vegetable Oils

Speaker: Prof. Kaichang Li, Oregon State University, USA




Abstract

Pressure sensitive adhesives (PSAs) are widely used in pressure sensitive

labels, tapes, stamps, Post-it notes and many other products. At present, PSAs

are mainly derived from petrochemicals that are not renewable and not sustainable. In this

presentation, we will disclose our new discovery that polyesters from polymerization of epoxy

compounds and carboxylic acids can have superior PSA properties. The polyesters can be prepared

from polymerization of epoxidized fatty acids such as epoxidized oleic acid, a bifunctional AB

monomer containing a carboxylic acid group (A) and an epoxy group (B); polymerization of

epoxidized soybean oils containing multiple epoxy groups and a dibasic acid such as dimer acids; or

polymerization of epoxy resins containing two epoxy groups and a dibasic acid. Innovative methods

for preparation of PSAs with superior properties have been successfully developed. The resulting

PSAs have been characterized for their molecular structures, thermal stabilities, and viscoelastic

properties. The peel strength, shear strength, tack, and aging stability of the resulting PSAs have also

been evaluated and will be discussed in detail in this presentation. The relationships between

chemical structures of the epoxy compounds and bibasic acids, and PSA properties have been

extensively investigated and will be present and discussed in detail.

Keynote Speech 12: Simulation and Visualizing study for Formation, Evolution

and Hereditary Mechanisms of Nano-Clusters During Solidification Processes of

Liquid Metals and Alloys under high pressures

Speaker: Prof. Rang-Su Liu, Hunan University, China




Abstract

In recent years, we have deeply investigated the solidification processes of

liquid metals of Al, Ag, Cu, Mg Na, Pb, Zn and alloys of Mg-Zn, Mg-Y,

Al-Mg, Al-Zn, Ca-Zn by molecular dynamics simulation for the systems with different sizes of

100,000, 1,000,000 and 10.000,000 atoms, respectively. By using the visualizing method, the

formation, evolution and hereditary mechanisms of nano-clusters, especially, under high pressures

the large-scale microstructurel evolution, the crystallization and the hereditary mechanisms during

their solidification processes have been clearly analyzed and described by the cluster type index

method (CTIM) proposed by authors. Recently, many important results obtained. Highly interesting,

for liquid Ni, it is found for the first time that there is an important phase transformation point from

FCC to BCC structures between 20 ~ 22.5GPa during the solidification processes from the same

initial liquid system at the same cooling rate. And the effect of increasing pressure is similar to that

of decreasing cooling rate for the phase transformation of microstructures during solidification

process of liquid metal Ni system, though they have different concrete effecting mechanisms.

Keynote Speech 13: Nonamaterials Composed of Activated Carbons and

Transition Metal Dichalcogenides in Applications of Sensing and Catalysis

Speaker: Prof. King-Chuen Lin, National Taiwan University, Chinese Taipei




Abstract

Palladium nanoparticles (Pd NPs) immobilized on a garlic skin-derived

activated carbons (GACs) was synthesized. The morphology, structure,

surface compositions, and textural properties of the GACs and Pd@GAC catalyst were examined by

15


Conference Guide

a variety of physicochemical characterization techniques which revealed a dispersion of Pd NPs with

average particle size of ca. 21 nm on sheet-like graphitized GACs. The Pd@GAC catalyst, which can

be facilely prepared with biowaste feedstocks, exhibited excellent catalytic performances for

efficient reduction of Cr (VI) with extraordinary stability and recyclability over at least five repeated

catalytic test cycles. On the other hand, we report the synthesis, characterization, and catalytic

application of ruthenium nanoparticles (Ru NPs) supported on plastic-derived carbons (PDCs)

synthesized from plastic wastes (soft drink bottles) as an alternative carbon source. The catalytic

activity of Ru@PDC for the reduction of potassium hexacyanoferrate (III), (K3[Fe(CN)6]), and new

fuchsin (NF) dye by NaBH4 was performed under mild conditions.

Further, we present ultra-sensitive sensing of a prostate-specific antigen (PSA), which is used as a

biomarker to detect prostate cancer, using a molybdenum series (MoO3, MoS2, and MoSe2) of

two-dimensional nanosheets (2D NSs). The design of a 2D NS-based PSA aptamer sensor system

was demonstrated based on a fluorescence turn-on mechanism in the presence of a target. The

detection limit of PSA was achieved to be 13 pM for MoO3 NSs, whereas the MoS2 and MoSe2

systems exhibited a detection limit of 72 and 157 pM, respectively. The in vitro bioimaging

measurements were also performed using confocal fluorescence microscopy. Herein, PSA detection

was successfully demonstrated in human embryonic kidney 293T (HEK) live cells. Moreover, the

MoO3, MoS2, and MoSe2 NSs exhibit excellent biocompatibility and low toxicity; thus, these 2D

NSs can be used as a promising sensor platform to detect prostate cancer. More chemical and

bio-sensing applications will be reported based on the nanomaterial of transition metal

dichalcogenides.

Keynote Speech 14: Manufacturing of hiHep Cells-Based Artificial Liver Support

System Using Digital Light Processing

Speaker: Prof. Jun Yin, Zhejiang University, China




Abstract

Currently, the liver cancer leads to the highest morbidity among all kinds of

cancers in the world. Due to the shortage of liver donors for transplantation,

the surgical resection is still considered as one of the most effective treatments for benign and

malignant liver tumors. However, the postoperative liver failure has been found to be the most

serious complication of a large number of patients with liver resection.

In this study, a scaffold with liver cells was designed with a serrated construct and fabricated as the

16


Conference Guide

artificial liver support system, which is used to replace the cutting off liver part to perform some of

the functions of synthesis and metabolism. A multi-material digital light processing (DLP)

technology was developed to manufacture the artificial liver support system. Gelatin methacryloyl

(GelMA) was used as the cell-laden bioink, where dECM (decellularized extracellular matrix) was

also added; and the hiHep cells were printed with GelMA/dECM hydrogels to fabricate designed

constructs. By measuring the printing resolution and the cell viability after printing, the optimized

printing parameters and formula of GelMA/dECM bioink were obtained. It should be noticed that

dECM was found to be helpful for both cell viability and printability of the bioink. The printed

artificial liver support system was found to have the similar function with original liver to synthesize

albumin and metabolize urea which provided a promising approach to solve liver failure for liver

function recovery and regeneration.

Keynote Speech 15: Development of integrated devices technologies by

miniaturization and new materials, and what after?

Speaker: Prof. Hiroshi Iwai, Tokyo Institute of Technology, Japan




Abstract

Electronics started in early 1900’s with the invention of vacuum tubes. This

was a great technological revolution. Then, the next technological evolution

started in early 1970’s by the invention of microelectronics or integrated circuits (IC) composed of

huge number of tiny MOSFETs with micrometer size. The performance and cost of the IC per

function have unbelievably improved by the continuous miniaturization of the MOSFETs. Now, the

microelectronics have evolved to the nanoelectronics and micro-/nano-electronics is the base of

smart society for today and near-future, which is characterized by internet, IoT, and AI. In other

words, without micro-/nano-electronics technologies, internet, IoT and AI would not exist.

However, it is expected that the miniaturization will reach its limit within 10 years, because of

several reasons.

Then, what about the development of integrated circuits or integrated devices (ID) technologies after

the end of miniaturization? Integrated circuits miniaturization technologies for logic and memory

will diffuse and diverse to various kinds of devices such as power, photovoltaic, sensor, energy

storage etc, in the coming IoT, 5/6G and AI era. In near future, many different kinds of devices will

be integrated or connected on-chip, in package, or by wired/wireless networks, and will form

integrated devices for smart system suitable for that era. The introduction of new materials will be

more active as well as the miniaturization of the various kinds of devices.

17


Conference Guide

Then, for a long term for several tens of years, what would be the direction of the integrated devices?

We will have to introduce bio systems in combination with the semiconductor devices. Today, AI

has made remarkable progress because of the introduction of deep machine-learning as well as the

tremendous performance improvement by the semiconductor device miniaturization. However, it is a

big problem that AI needs extremely huge power for the leaning of each single application. On the

other hand, power/energy consumption of bio system such as brains of human, animals and insects

are extremely low, and those brains are extremely efficient. There will a big difference in the

hardware between the semiconductor devices and brains, and the semiconductor devices cannot

compete with the bio system by several reasons.

In this talk, brief history of integrated circuits development with miniaturization and introduction of

new materials are explained. Then, integrated devices developments for near and long future will be

discussed.

Keynote Speech 16: Failure Analysis of Laminated Composites

Speaker: Prof. Zheng-Ming Huang, Tongji University, China




Abstract

In this report, we firstly point out that all kinds of composite failures can be

analyzed through micromechanics only. One apparent reason is as such: given

the composite subjected to any arbitrary load, one cannot tell when the interface debonding between

the fiber and matrix will occur if he does not know the internal stresses in the fiber and matrix. The

latter is obtainable only by micromechanics. And this problem has been resolved, and is presented in

this report.

Secondly, we demonstrate that the internal stresses in the fiber and matrix obtained by a

micromechanics theory are homogenized quantities, which must be converted into ―true‖ values

before a failure assessment can be efficiently made. The true stresses of the matrix are very much

different from its homogenized counterparts. It is the true stresses of the matrix that open the door to

solving all kinds of composite failure problems.

Lastly, we show that the failure and strength of a laminated composite subjected to various types of

loads can be efficiently assessed only using the original fiber and matrix properties, plus a transverse

tensile strength of a unidirectional composite if an earlier interface crack is involved. Several

examples are included.

Keynote Speech 17: Multi-scale Failure Behavior of Triaxially Braided

Composites

Speaker: Prof. Chao Zhang, Northwestern Polytechnical University, China




Abstract

The anisotropic feature and prolific geometry forms (laminates, 2D and 3D

textiles) of composites, as well as the revealing of novel manufacture

technologies, provide great potential for its application in various fields, including aerospace,

automotive, renewable energy and energy storage et. al. This, on the other aspect, also raises

increasing demands on knowledge and methodologies for the failure analysis of composite structures

under various complicated service conditions. The complexity of failure behavior for composites is

due to the presence of failure phenomena (microcracking, fiber breakage/buckling and delamination)

at different dimensional scales and the interactions between each other. These failure behaviors can

also be influenced by manufacture induced imperfections, specimen sizes, loading rates and

environmental conditions. To address these problems, multidisciplinary, experimental and numerical

combined approach is necessary. In this work, a multi-scale method is proposed to investigate the

impact response of 2DTBC. A validated meso-scale finite element (FE) model is adopted to simulate

the failure behavior of the braided composites under different load conditions, taking into

consideration the realistic test boundary conditions. Followed, a meso-macro modeling method for a

six-layer braided composite plate is developed to study the impact behavior of the 2DTBC, providing

a new tool for impact simulation of textile composites with great advantages in capturing the failure

initiation and progression during an impact load. The impact simulation results compare well with

the experimental results and provide insights on the impact failure characters of this material.

Interfaces

Speaker: Dr. Yang Yang, East China Normal University, China

Time: 08:30-09:00, Thursday Morning, August 22, 2019



Abstract

The properties of solid-liquid interfaces (SLIs) govern a wide variety of

processes of technological import, e.g., wetting, heterogeneous nucleation,

casting, and crystal morphology and growth. We examined the chemically heterogeneous Al-Pb SLI

to determine how interfacial structure and dynamics affect phenomena of experimental interest.

Transmission electron microscopy experiments show that liquid Pb inclusions undergo Brownian

motion within a solid Al matrix, using molecular-dynamics simulations as well as the

characterization methodology explicitly developed for the Al-Pb SLIs, we found Al-Pb solid-liquid

interfaces [Phys. Rev. Lett, 110, 096102 (2013)] exhibit premelting transition below the melting

point of Al. I will present in this talk: i) the roles played by Al diffusion and the interfacial

premelting phase transition at the solid-liquid interfaces in the phenomenon (Brownian motion of Pb

inclusion within the Al matrix). ii) The spreading kinetics of Pb droplets on Al substrate, the effect of

this premelting on the droplet spreading kinetics, and effect of premelting on the droplet equilibrium

contact angle. iii) Some preliminary results on the interactions between the Al crystal-melt interfaces

and the liquid phase Pb inclusions during the rapid solidification

Abstract

Graphene nano-sheets and its derivatives have been applied in many areas

cementitious materials. In this presentation, a short review on recent research results about graphene

oxide (GO) modified cement-based materials was made. The review mainly discussed the influence

of GO on properties of cementitious materials in term of cement hydration, mechanical properties,

etc. Furthermore, good dispersion of GO in cementitious materials is critical in achieving the

enhancement of these nano-sheets. Up to now, commercial superplasticizers such as sulfonated

naphthalene formaldehyde condensates or polycarboxylates are used as dispersing agents of GO

nano-sheets. In our lab, we have prepared a new dispersion agent. Compared to commercial

superplasticizers, the prepared dispersant shows better dispersion property in pore solutions, and the

resulting GO-contained mortars exhibit greater compressive strength and flexural strength.

Keynote Speech 20: Solute Convection on Pore Shape Development in Solid

Speaker: Prof. Peng-Sheng Wei, National Sun Yat-Sen University, Chinese Taipei




Abstract

The effects of transport processes on the shapes of pores resulting from

entrapped bubbles during solidification are numerically and theoretically

investigated. Bubble formation results from supersaturation of dissolved gases

in the liquid ahead of the solidification front. Pore formation and its shape in solid influence not only

microstructure of materials, but also contemporary issues of biology, engineering, foods, geophysics

and climate change, etc. In this study, equations of fluid flow, heat transfer and solute concentration

are solved by using commercial COMSOL computer code. Scaling analysis shows that solute

convection plays an important role inpore shape development during solidification. Solute

convection influences not only thickness of solute concentration on the bubble cap, but also time for

bubble entrapment. This work is critical to understand and control different types and sizes of pore

shapes and their distributions in the solid in advance.

Keynote Speech 21: Magnetic and optical properties of metal-phthalocyanines

Speaker: Dr. Wu Wei, University College London, UK




Abstract

Organic semiconductors based on phthalocyanine molecules have been proven

to be a promising material candidate in nano-magnetism, optical devices, and

quantum information processing. These organic materials are formed by the

one-dimensional molecular chains. In this presentation, I will first discuss

recent theoretical and experimental work on the photon-detector devices consisting of

copper-phthalocyanines with fast optical response. In addition, I will discuss the magnetic properties

of transition-metal phthalocyanines, including copper-, cobalt, chromium-, and

lithium-phthalocyanines. We have demonstrated theoretically and experimentally that

cobalt-phthalocyanines have a magnetic transition temperature higher than the boiling point of

nitrogen, which is very promising for magnetic information storage and spintronics. Theoretically we

have also shown that there is a huge potential in magnetism for lithium-phthalocyanines, in which a

large exchange interaction arises from the p-orbitals of carbon/nitrogen atoms. The strong

anti-ferromagnetic interactions in these molecular chains can be explored for spintronics based on

anti-ferromagnetism. By combining copper- and cobalt-phthalocyanines, we can form ferromagnetic

chains artificially, leading to organic magnetic meta-materials. Using optical excitations and

inter-system crossing, optical control of spin-spin interaction can be realized in molecules, which has

a great potential in spintronics and optoelectronics. We can also combine the graphene quantum

materials with phthalocyanines to fabricate novel optic-al devices.

Keynote Speech 22: Two-color coherent control of atomic multiphoton ionization

with high-order harmonics: Coherent imaging of an attosecond electron wave

Speaker: Prof. Abdelkader Makhoute, Moulay Ismail University, Morocco




Abstract

We present a theoretical study of the main characteristics of two-color

photoionization spectra obtained when atoms are subjected to an intense

radiation pulse containing the fundamental of an infrared laser and one of its higher harmonics. The

calculation is performed by numerical integration of the time-dependent Schrodinger equation for a

helium, neon and argon atoms. We present the general properties of the spectra and angular

distributions as well as the possible occurrence of interferences between the laser-assisted process

and above-threshold ionization. Our results indicate that such interference effects, which can lead to

partial coherent control of the photoionization process, can be observed at moderate laser intensities

within the reach of currently operated laser and harmonic sources. An agreement with the

experimental results for neon photoionization has been obtained.

Keynote Speech 1: The finite analytic numerical methods for heat conduction and

fluid flows in heterogeneous media

Speaker: Prof. Xiaohong Wang, University of Science and Technology of

China, China


Location: Tai Bai Shan Hall (太白山厅), 1st Floor, Xi’an Grand Dynasty

Culture Hotel (西安古都文化大酒店), China

Abstract

For various problems in engineering, such as steady-state heat conduction in

composite materials or steady-state seepage in petroleum industry, it is suitable to describe them with

quasi-Laplace equation. For the strong heterogeneous case, it is a challenge and long-standing

problem to perform an accurate numerical simulation. We find out that this difficulty is caused by

the appearance of the singularity when the conductivity is heterogeneous. A finite analytic numerical

scheme is proposed to deal with this problem. Numerical examples show that the proposed numerical

scheme makes the convergences much quickly than the traditional methods. Under few grid

refinements, such as 2×2 or 3×3 subdivisions for 2D problem and 2×2×2 or 3×3×3 subdivisions for

3D problem, the proposed numerical scheme can provide rather accurate solutions. Especially, the

convergent speed of the numerical scheme is independent of the conductivity heterogeneity. In

contrast, when using the traditional numerical schemes to simulate the heat conduction or fluid flows

in a strong heterogeneous medium, the refinement ratio for the grid cell needs to be increasing

dramatically to get an accurate result.

Keynote Speech 2: Mandatory strong links in semiconductor engineering

between research, innovation and training in the context of the emergence of the

digital society

Speaker: Prof. Olivier Bonnaud, University of Rennes 1, France




Abstract

Semiconductor and device physics are the basic knowledge of

microelectronic circuits and systems. These components are at the heart of

new objects, especially smart and connected objects, which are the main vectors of the Internet of

Things (IoT). These IoTs govern the evolution towards a digital society, which should be at the

forefront of the future global economy by covering all social sectors (communications, energy,

health, etc.). But connected objects include many electronic functions and their design and

manufacture become extremely complex due to the diversity of materials, size reduction and digital

processing. The challenge today is to ensure that a community of researchers, engineers and recent

graduates can share their knowledge and know-how with a broad spectrum that includes

semiconductor physics, analog and digital electronics, but also many other skills such as transduction,

transmission, energy harvesting, and so on. They must be able to work as a team to create and

produce innovative connected objects combining several technologies. This approach is part of the

French national coordination strategy for the teaching of microelectronics and nanotechnologies,

which manages 12 joint inter-university centers with dedicated platforms for design, technological

processes, characterization and testing. The innovative practice proposed to the entire community is

developed and covers ULSI electronics but also power electronics, very high frequency and low

temperature technologies (large area electronics, plastronics, etc.) including nanometric

manufacturing processes in cleanrooms, nano-characterization, and design involving multi-physical

approaches. Several examples of practice answering to the needs will be presented and discussed.

Keynote Speech 3: Structural reliability of the InSb infrared focal plane array

detector subjected to liquid nitrogen shocking tests

Speaker: Prof. Qingduan Meng, Henan University of Science and technology,

Abstract

The typical failure patterns, such as, the local fracture of the InSb chip, the

local delamination of the InSb chip, and the local disconnecting of the indium bump array appearing

in the InSb infrared focal plane arrays (IRFPAs) detector in liquid nitrogen shocking tests, limit its

batch production capacity. Focusing on these problems, we employ theoretical calculation, modeling

and simulation, and experimental verification to search the effective approach to solve these

problems. Firstly, employing the calculation theory suitable to calculate the thermal stress in the

elastic multilayer system, the structural modeling of InSb IRFPAs created with ANSYS and the

typical failure distribution characteristics in the InSb IRFPAs, such as the local delamination region

and its covering range, the origin of the fracture, the distribution of the cracks, its propagation

direction, and its termination location, etc. we will ascertain the local failure mechanism of the InSb

IRFPAs in liquid nitrogen shocking tests. Secondly, we assess the effects from the balanced

composite structure (BCS) in the InSb IRFPAs assembly, and obtain the suitable structural parameter

ranges to eliminate the thermal mismatch stress. These results will significantly improve the mass

production capacity of the InSb IRFPAs.

tunnel FETs and negative capacitance FETs. In this talk, I introduce the current status on our PNBT

research and also talk about PNBT applying to RF Energy harvesting, where the high efficiency

rectification on the ultralow input power below -30dBm is a key technical challenge.

Keynote Speech 5: Polarization Coulomb field scattering in GaN-based HFETs

Speaker: Prof. Zhaojun Lin, Shandong University, China




Abstract

Due to inverse piezoelectric effect and device processing, the uneven strain

distribution of the barrier layer for GaN-based heterostructure field-effect

transistors (GaN-based HFETs.) is unavoidable. A new scattering mechanism, the polarization

Coulomb field scattering which is related to the uneven strain distribution of the barrier layer, is

proposed. This talk introduces the theoretical model of the polarization Coulomb field scattering and

the relationship between the polarization Coulomb field scattering and the device structures of

GaN-based HFETs. Moreover, the influence of the polarization Coulomb field scattering on the

characteristics of GaN-based HFETs are also discussed. Such as, the effect of the polarization

Coulomb field scattering on parasitic source access resistance and extrinsic transconductance in

AlGaN/GaN HFETs, it is found that the variation of the parasitic source access resistance originates

from the polarization Coulomb field scattering, and the effect of the polarization Coulomb field

scattering on the parasitic source access resistance is more significant for the device with a longer

gate length or a shorter gate-source distance. The behaviors of the measured transconductance for the

fabricated AlGaN/GaN HFETs confirm the effect of polarization Coulomb field scattering. In

addition, the effects of the polarization Coulomb field scattering on device linearity in AlGaN/GaN

HFETs is also found. The single-tone power of the AlGaN/GaN HFETs with different gate widths

was measured. A distinct improvement in device linearity was observed in the sample with a larger

gate width. The analysis of the variation of the parasitic source access resistance showed that, as the

gate bias is increased, the polarization Coulomb field scattering can offset the increased polar optical

phonon scattering and improve the device linearity.

Keynote Speech 6: Development of Efficient CFD Solver for Ship Flows and

Ocean Engineering Flows

Speaker: Prof. Decheng Wan, Shanghai Jiao Tong University, China




Abstract

In this presentation, an efficient overset techniques for simulating the

complicated viscous flows around ship and ocean structures is introduced. An

in-house CFD solver naoe-FOAM-SJTU is developed using the OpenFOAM toolbox which consists

of main three special modules of numerical wave tank, 6DOF body motion module and mooring

system module. In the numerical wave tank, several wave-makers including piston wave maker, flap

wave maker and inlet wave boundary are developed to numerically generate regular waves, irregular

waves, directional waves, freak waves, rogue waves, focused waves, etc. An artificial spongy layer is

set up at the end of the computation domain to absorb the wave reflection. In the 6DOF body motion

module, overset grid method is applied for handling body motion. The main procedure of the overset

grid method consists of three steps: projection, hole cutting and fringe-point interpolation. The local

body-fit grids are allowed to be arbitrarily embodied into an orthogonal background grid. Therefore

the motion of ship and ocean structures in fluid can be treated easily by the overset grid technique

without regenerating the mesh. In the mooring system module, three types of mooring lines using

taut method, catenary method and piecewise extrapolation method are developed to treat the floating

structures. In order to validate the solver, several numerical examples of flows around surface ship

(Wigly, KCS, DTMB5415, Catamaran), green water of ship motion in waves, self-propulsion of ship

motion, LNG tank sloshing, wave run-up and impact loads on floating platform with mooring system,

VIV for risers and VIM for deep-sea platform, as well as wake flows of offshore floating wind

turbine are presented.

Keynote Speech 7: Space Magnetism and Superconductivity: Diamagnetic

Expulsion, Meissner Effect, Magnetic Pressure and Quantum Trapping Lead to

the Origin and Stability of the Saturn Rings

Speaker: Prof. Vladimir Tchernyi (Cherny), the Modern Science Institute,

SAIBR, Russia




Abstract

Many questions still exist about the origin, dynamics, evolution and age of the Saturn rings. Galilei

observe rings in 1610. J.C. Maxwell, 1859 proved the rings consist of an infinite number of

separated particles. NASA had made four missions to Saturn: Pioneer, Voyager-1 and -2 and Cassini

(2004-2017). But still the answer is needed to the question: ―After the Cassini grand finale, is there a

final consensus on the rings’ origin and age?‖

The existing theory of the rings emerging from fragments of an asteroid that came close to the planet.

Cassini found no iron and rings consist of 93% of ice and 7% of carbon. To support theory of gravity

defragmentation NASA decided to use Titan-sized icy satellite. This theory and others do not

confirmed rings existence and particles property.

Also rings could emerge from the particles of a protoplanetary cloud moving on chaotic orbits

around Saturn. To shift orbits to the equator necessary introduce an additional force. Existence of

Saturn magnetic field and temperature 70-100K bring us to idea of the particles diamagnetism and

superconductivity. Solution of electromagnetic problem could be presented as two steps. First, all the

chaotic orbits of icy particles are gradually moving to the magnetic equator plane due to

diamagnetism and Meissner phenomenon after appearance of Saturn magnetic field. Final picture is

similar to iron particles picture that form the same shape around a magnet on a laboratory table.

Secondly, because of quantum locking each particle becomes to be locked within three-dimensional

magnetic well due to Abrikosov quantum vortex phenomenon for superconductor. And each icy

particle is in the stable position, preventing its own horizontal and vertical shift. This mechanism is

valid and it works even if particles may have a small fraction of superconductor.

For electromagnetic modeling the magnetization relationships for magnetically uniform spherical

particles are introduced as a necessary component to account for dynamics of diamagnetic particles

in the gravitational and magnetic fields. The magnetostatics problems of a solitary magnetized

sphere and of a spherical particle among identical particles scattered in a disk-like structure are

solved. The differential equations of the particles motion in superposition of gravitational force of

30


Conference Guide

attraction and diamagnetic repulsive force can account for the Saturn rings’ stability. The same

electromagnetic modeling was made for superconducting particles and it was demonstrated that all

particles should come to magnetic equator plane. In both case the main role is playing interaction of

the icy particle with the magnetic field of Saturn. Contribution to the rings matter also may come

from the frozen water particles generated from the Saturn sputniks geysers due to magnetic coupling

between planet and satellites like it happening with satellite Enceladus, and that may even create a

new ring. It follows that rings was created in the early time of the magnetic field of Saturn

appearance.

Keynote Speech 8: The limits of Riemann solutions to the Euler equations of

one-dimensional compressible fluid flow with a source term

Speaker: Prof. Zhiqiang Shao, Fuzhou University, China




Abstract

In this talk, we discuss the limits of Riemann solutions to the Euler equations

of one-dimensional compressible fluid flow with a Coulomb-like friction as

the adiabatic exponent tends to one. Different from the homogeneous equations, the Riemann

solutions of the inhomogeneous system are non self-similar. It is rigorously shown that, as the

adiabatic exponent tends to one, any two-shock Riemann solution tends to a delta shock solution of

the pressureless Euler system with a Coulomb-like friction, and the intermediate density between the

two shocks tends to a weighted δ-mesaure which forms the delta shock; while any

two-rarefaction-wave Riemann solution tends to a two-contact-discontinuity solution of the

pressureless Euler system with a Coulomb-like friction, whose intermediate state between the two

contact discontinuities is a vacuum state. Moreover, we also give some numerical results to confirm

the theoretical analysis. This is a joint work with Shouqiong Sheng.

Keynote Speech 9: Numerical simulation of laser-induced thrombus formation by

Particle method to achieve personalized treatment of laser dermatology

Speaker: Prof. Bin Chen, Xi’an Jiaotong University, China


Location: Tai Bai Shan Hall (太白山厅), 1st Floor,Xi’an Grand Dynasty


Abstract

Port wine stains (PWS) are congenital vascular malformations that

progressively darken and thicken with age. Laser therapy is currently the

most effective way in clinical practice for PWS. Pulsed dye laser (PDL) with wavelength of

585/595nm is a commonly used treatment for Port Wine Stain birthmarks (PWS). However, deeper

components of PWS are often resistant to PDL owing to its short wavelength. Deeper penetrating

lasers, including the long pulsed Nd:YAG laser can be used. However, because of its relatively weak

absorption by blood, single-pulse Nd:YAG laser requires high energy density to cause effective

vessel damage, which may inflict undesirable burning to surrounding collagen. Multi-pulse laser has

great potential in clinical treatment because it needs less energy density for each pulse. According to

our in vivo experimental study of the transient thermal effects of low-energy multi-pulse Nd:YAG

laser on blood vessels, thrombus that completely occludes the vessel lumen is the prerequisite for

thread-like appearance, which is the desirable clinical end point. In this work, laser-induced

thrombus formation in microvessel was numerically simulated by particle method. Characterized by

thrombus that completely occludes the vessel lumen, optimized laser parameters for multi-pulse

treatment are recommended for vessels with different diameter and depth including frequency, pulse

number, and incident energy in each pulse. In conjunction with laser speckle imaging of skin tissue

to detect vessel morphology, intelligentized laser treatment of vascular dermatology can be achieved.

Keynote Speech 10: High-fidelity numerical modeling of water wave propagation

over coastal area using a viscous flow model

Speaker: Prof. Xizeng Zhao, Zhejiang University, China




Abstract

The performance of interFoam (a widely used solver within OpenFOAM

package) in simulating the water wave propagation and its interaction with

ocean structures has been reported to be sensitive to the temporal and spatial resolution. To facilitate

more fidelity simulations, a high-fidelity numerical model is built based on a high-order accurate

Navier-Stokes model, which employs the VPM (volume-average/point-value multi-moment) scheme

as the fluid solver and the THINC/QQ method (THINC method with quadratic surface representation

and Gaussian quadrature) for the free-surface capturing. Simulations of regular waves in an

intermediate water depth are conducted for the model validation and the results are assessed via

comparing with the analytical solutions. The performance of the present model and interFoam solver

in simulating the wave propagation is systematically compared in this work. The results clearly

demonstrate that compared with interFoam solver, the present model significantly improves the

dissipation properties of the propagating wave, where the waveforms as well as the velocity

distribution can be substantially maintained while the waves propagating over long distances even

with large time steps and coarse grids. Finally, the model is applied to model water wave

propagation in super long wave tank and interaction with different coastal structures.

Transmission Lines Induced by Wildfires

Speaker: Prof. Fei You, Nanjing Tech University, China




Abstract

Wildfires have incurred flashovers between HVTLs (High-Voltage

Transmission Lines) or from HVTLs to ground or even outages of grid at

times. The detailed behaviors, properties and key factors of flashovers and fire environments

surrounding the right-of-ways (corridors) that usually induce flashovers of HVTLs have been

described and recognized, among which altered conditions of HVTLs (metallographic phase, surface

morphology, sagging, molten droplets) by wildfires were addressed, and effects of vegetation fuel

(amount, type, moisture content and location), topography (steepness), climatic conditions

(temperature, humidity, wind speed) on them were investigated. Typical accidents were presented

and analyzed to figure out above processes and parameters. Finally, based on above facts and

analyses, potential mechanisms of flashovers derived from wildfires to cover super-long distance air

gap in dozens of meters were postulated and proposed.

Abstract

This study examined the properties of self-compacting

concrete (SCC) with a fixed water–cement ratio of 0.32

in which a portion of the Portland cement was replaced

by stainless steel reducingslag(SSRS)in weight ratios of

0%, 10%, 20%, 30%, 40% and 50%. The fresh and

various engineering properties are discussed. The 0%,

10%, 20% and 30%replacement weight ratio met the

requirementof fresh slump flow 600mm,V-funnel flow

time 7~20sec, box-filling height 300mm. The

compressive strength of 0%, 10%, 20%, 30%, 40%

replacement specimenwere over the 420kgf/cm2. The

ultrasonic pulse velocity of the SSRS SCCis over 4500

m/s after the age of 28 days. The surface resistance of

the0%, 10%, 20%, 30% substitution SSRS SCCcould

reach the required value of 20 kΩ-cm to prevent

corrosion. Thereby, when the SCC within 30%

SSRSreplacement forthe Portland cement in weight, the

fresh and engineering properties were conform to the

SCC requirement. The need for cement could thereby

be reduced, which can contribute to resource recycling

and environmental protection.

Title: Reactions of conjugate addition of

nucleophilic reagents with coumarins – a new

Abstract

Coumarins are natural compounds with wide

application in organic synthesis as acceptors in different

organic reactions with nucleophilic reagents and

dienophiles in Diels-Alder reactions as well in reactions

of [2+2] or [2+3] cycloaddition and as intermediates in

the synthesis of products of practical interest. On the

other hand, especially important are their antimicrobial,

antiviral, anticancer, enzyme inhibition, anti-HIV, and

antioxidant activities as well as their influence over

central nervous system. A third large area of application

of coumarin derivatives are modern technologies They

can be applied as excellent luminophores and laser

dyes. Coumarin derivatives may be used as ligands for

metal complexes and for modification of organic and

inorganic supports.

The investigations on the chemical behavior of the

3-substituted 2-oxo-2H-1-benzopyranes (coumarins)

toward nucleophilic reagents represented them as good

acceptor in the 1,4-addition reactions.

Reactions of the 3-substituted coumarins with

organomagnesium, and organozinc reagents as well as

with Ivanov’s reagent were carried out and the

corresponding 2-oxochromanes were isolated with

good yields. The reactions with their analougs

1,2-benzoxaphosphorine as substrate had the same

synthetic progress but in these cases were isolated only

two of possible diastereoisomers. The reactions were

carried out under ultrasound irradiation and the yields

of the target products were higher and the results were

accurate and precise.

Title: Band Dependent Interlayer f-Electron

Hybridization in CeRhIn5

Name: Qiuyun Chen

Affiliation: Science and Technology on Surface

Physics and Chemistry Laboratory


Abstract

A key issue in heavy fermion research is how subtle

changes in the hybridization between the 4f (5f) and

conduction electrons can result in fundamentally

different ground states. CeRhIn5 stands out as a

particularly notable example: when replacing Rh with

either Co or Ir, antiferromagnetism gives way to

superconductivity. In this photoemission study of

CeRhIn5, we demonstrate that the use of resonant

angle-resolved photoemission spectroscopy with

polarized light allows us to extract detailed information

on the 4f crystal field states and details on the 4f and

conduction electron hybridization, which together

determine the ground state. We directly observe weakly

dispersive Kondo resonances of f electrons and identify

two of the three Ce 4f15/2 crystal-electric-field levels

and band-dependent hybridization, which signals that

the hybridization occurs primarily between the Ce 4f

states in the CeIn3 layer and two more

three-dimensional bands composed of the Rh 4d and In

5p orbitals in the RhIn2 layer. Our results allow us to

connect the properties observed at elevated

temperatures with the unusual low-temperature

properties of this enigmatic heavy fermion compound.

Abstract

Searching for Majorana zero mode (MZM) is a crucial

step towards topological quantum computation.

Through systematically study (Li0.84Fe0.16)OHFeSe

thin films with a superconducting transition

temperature of~42 K by scanning tunneling

spectroscopy, we identified discrete low-level Caroli-de

Gennes-Matricon (CdGM) states together with a robust

zero-bias conductance peak (ZBCP) in free vortex cores

on FeSe-terminated surfaces. Due to small Fermi energy,

the low-level vortex states are well separated from each

other. While previous STM studies claim

(Li1-xFex)OHFeSe is a plain s-wave superconductor,

theoretical studies indicate ZBCP shall not present in

the vortex states of a s-wave superconductor.

Considering the surface state observed by angle

resolved photoemission spectroscopy and confirmed by

band calculations in this system, we suspect this ZBCP

may be attributed to a MZM due to the chiral

topological surface state. In addition, we demonstrate

Title: Characterizations of Hydrogen on

TiO2(011)-(2×1) single crystal

Name: Qunqing Hao


Physics and Chemistry Laboratory


Abstract

TiO2 is widely used due to its outstanding characters in

energy materials and H2 generated by

photo-catalytically dissociating H2O is one of the most

significant application. As a result, water splitting on

TiO2 has been studied profoundly in past fifteen years.

However, only a few researches on hydrogen behavior

have been reported on TiO2(011)-(2×1), which is a

model structure in studying TiO2. Only Tao’s group has

reported hydrogen diffusion by using STM and DFT

calculation on this surface. After all, the systematic

investigation of H/TiO2(011)-(2×1) has not been

reported at present. In this work, we have investigated

behavior of hydrogen on TiO2(011)-(2×1) including

adsorption, diffusion as well as desorption by TPD and

PSD using deuterium substitution. Insightful evolution

of temperature dependent deuterium diffusion was

comprehensively observed in our work, which reveals

that deuterium is favorable to diffuse into bulk phase at

about 300K and then desorption at higher temperature.

Electronic states were also measured by PES at

different conditions. A linear increase of band gap states

density was detected along with the coverage of OtopD,

which shows a defect dependent behavior just like

ObrH/TiO2(110). Our work provide a omnibearing

sight in characters of hydrogen behavior on

TiO2(011)-(2×1). The results could improve the

comprehending in the mechanism and dynamics of

hydrogen behavior on TiO2(011)-(2×1), which should

be one of the key steps of H2 generated in the study of

energy materials.

Title: Self-supported Ni(OH)2/MnO2 on CFP as a

Flexible Anode towards Electrocatalytic Urea

Conversion: The Role of Composition on Activity,

Redox States and Reaction Dynamics

Name: Jianfang Meng

Affiliation: School of Materials Science and

Engineering,Tianjin University


Abstract

Nickel-based catalysts accomplish the direct conversion

of urea to pure hydrogen via electrochemical oxidation;

yet mechanistic understanding is lacking. Synthesizing

a series of carbon fiber paper (CFP) supported

Ni(OH)2/MnO2 catalysts, we explored relevant redox

transitions and catalysis of both UOR (urea oxidation

reaction, in KOH-with-urea) and OER (oxygen

evolution reaction, in KOH). Cyclic Voltammetry (CV)

in KOH-only solution demonstrated a more cathodic

transformation from Ni(III/IV) to Ni(II) compared with

that in KOH-with-urea solution. The water oxidation

overpotential was shifted to higher values (from 0.48 to

0.53 VRHE) as the Mn:Ni atom ratio increases in

CFP-NiMn films. In contrast, a higher Mn content

results in higher UOR activity and lower onset potential

in KOH solution containing urea (1.395 to 1.375

VRHE). Quasi in-situ, freeze-quench X-ray absorption

spectroscopy (XAS) at the Ni and Mn K-edges was

employed to uncover oxidation state changes as well as

structural transformations at the atomic level showing

that CFP-Ni(OH)2 underwent oxidation state changes

by about 1.15 e- and 0.21 e- per Ni ion during OER and

UOR processes, respectively, versus only 0.71 e- and

0.07 e- per Ni ion in CFP-NiMn2.4. Mn incorporation

can stabilize the Ni in lower valent states in a mixed

NiMn catalyst without significant changes in oxidation

state and structure. The here investigated, readily

synthesized CFP-NiMn films exhibit opposite activity

trends in KOH and KOH-with-urea electrolytes: Mn

incorporation depresses water oxidation, but it

promotes the urea oxidation process. We propose that

the water oxidation rate (OER) is positively correlated

with the capacity for accumulation of Ni and Mn

oxidation equivalents, while the urea oxidation (UOR)

rate is negatively correlated with this capacity. Our

work offers a mechanistic guideline for designing and

synthesizing nonprecious metal-coupled Ni-based

catalysts with appropriate redox-properties for

urea-oxidation applications.

Title: THERMOELASTIC EQUILIBRIUM AND

SUPERFUNCTIONALITY IN

PRE-TRANSITIONAL MATERIALS WITH

DEFECTS

Name: Ye-Chuan Xu

Affiliation: Nanjing University of Information Science

and Technology


Abstract

Materials with displacive transformations often have

advanced properties in pre-transitional states. However,

the thermodynamics and its effect on properties of

pre-transitional materials with typical defects such as

dislocations and coherent precipitates are not

investigated. Here we show that the local stress

generated by static defects produces stress-induced

displacive transformation forming nano-embryos of the

product phase. We report a discovery of the new effect,

thermoelastic equilibrium between these embryos and

the pre-transitional phase. The embryos

anhysteretically change the equilibrium size in response

to changes in the applied stress or magnetic field

leading to superelasticity and supermagnetostriction.

Similar response to cooling changes the coefficient of

thermal expansion and elastic modulus, which may

explain the invar and elinvar behaviors. This new

mechanism provides a route for developing a new class

of superfunctional materials.

Title: Promising thermoelectric properties and

anisotropic electrical and thermal transport

Name: Yu Li

Affiliation: Shenzhen University


Abstract

Motivated by the recent experimental synthesis of

atomic-thick SnTe [Liu et al., Science 353(6296), 274

2016] exhibiting a layered orthorhombic phase similar

to SnSe, we carried out systematic investigations on its

electronic, thermoelectric, and phonon transport

properties based on a combination of density functional

theory and Boltzmann transport theory. Our results

indicate that the monolayer is dynamically stable with a

band gap of 1.05 eV. A considerable figure of merit (ZT)

is predicted to be 2.9 for n-type doping and 2.2 for

p-type doping along the armchair direction at a

moderate carrier concentration of 1020cm 3. The

electronic band structure and the Fermi surface with

multi-valleys lead to band convergence and anisotropic

transport behavior. The synergistic optimization of

Seebeck coefficient and electrical conductivity is

achieved in anisotropic monolayer SnTe, due to the

independence of carrier relaxation time and directional

effective mass. A maximum power factor of 37

mW/(mK2) can be achieved for the n-type SnTe

monolayer along the armchair direction, almost two

times as high as that in the zigzag direction. However,

the anisotropy of intrinsic lattice thermal conductivity is

relatively low and strong phonon anharmonicity is

found due to the coexistence of weak bonding and

resonant bonding.

Title: Nano-microstructure and Solidification and of

A Hypereutectic Zn-Al Alloy

Name: Henry Hu

Affiliation: University of Windsor


Abstract

Zinc-aluminium alloys, in particular the eutectic Zn-Al

alloy, are often employed to coat steel for corrosion

protection. With additional Al contents, hypereutectic

Zn-Al alloys provide improved corrosion resistance.

43


Conference Guide

Since Zn-Al coating on steel involves solidification, it

is essential to develop scientific understanding of its

solidification behavior and relation to microstructure

evolution. In this work, Zn-6wt.% Al hypereutectic

alloy was solidified under different cooling rates of 0.04,

and 10 oC/s . The effect of cooling rates on the

solidification of the alloy was investigated according to

thermal histories recorded by temperature

measurements on cooling curves. The slow cooling of

0.04 oC/s reveals the detailed solidification sequences,

at which different phases form, due to its

near-equilibrium condition. The observation of no

apparent undercooling on the cooling curve of the alloy

under the high cooling condition implies a significant

refinement of the matrix microstructure structure. The

metallographic analyses by scanning electron

microscopy (SEM) and energy dispersive X-ray

spectroscopy (EDS) indicate that four different phases,

the primary γ-ZnAl phase, the eutectic β-Zn phase, and

the eutectoid α-Al and eutectoid β-Zn phases

decomposed from the eutectic γ-ZnAl phase appear in

the samples solidified under the difference cooling rates.

However, as the cooling rate increases to 10.00 ℃/s,

which suppresses the eutectic and eutectoid reactions,

the average size of the eutectic phase is significantly

reduced by more than an order of magnitude from the

micron size (7.58 μm) for the cooling rate of 0.04 ℃/s

to the nano size (0.58 μm = 580 nm) for the cooling rate

of 0.04 ℃/s. The results of the measured eutectic

spacing indicate that an increase in the undercooling

decreases the spacing between eutectics, and the

eutectic spacing is inversely proportional to the

undercooling. Evidently, the high cooling rate of 10

0C/s suppresses the growth of the eutectoid phases, and

results in the formation of the nano-sized eutectoid α-Al

and eutectoid β-Zn phases, and the considerably refined

microstructure.

Title: Comparison of optoelectronic properties of

NiO films deposited by direct current magnetron

sputtering and high power impulse magnetron

sputtering

Name: Sheng-Chi Chen

Affiliation: Ming Chi University of Technology


Abstract

High power impulse magnetron sputtering (HiPIMS)

technology has attracted lots of attention due to its high

target ionization rate. This characteristic is desirable in

preparing metal compounds with complex valence

states. In the current work, NiO films were deposited by

HiPIMS and direct current magnetron sputtering

(DCMS) at various oxygen flow ratios. The films’

structural and optoelectronic properties were

investigated. The results show that, thanks to the

enhanced Ni3+ ion density formed during the HiPIMS

deposition process, more nickel vacancies are formed in

the film leading to the film’s carrier concentration

improving significantly. NiO films deposited by

HiPIMS possess much better p-type conductivity than

the films deposited by DCMS. Additionally, with

oxygen flow ratio increase, more interstitial oxygen can

be introduced, which can also enhance the film’s p-type

electrical conductivity. However, these defects reduce

the film’s transmittance.

Abstract

Ultra-high-temperature ceramic fibers have high

good ablation/oxidation resistance, which have great

promise for high-temperature applications. In this paper,

a novel single-source precursor was synthesized by

co-polymerisation of HfCl4, ethylenediamine, and

allylamine. The obtained precursor featured a backbone

comprising Hf–N and CH=CH groups and exhibited

good melt spin ability due to its relatively linear-chain

structure, optimal molecular weight (Mn=2529g/mol),

and suitable softening point (110–146°C). In addition,

Hf-based ceramic fibers were prepared by sequential

melt hand-drawing, ultraviolet and chemical vapour

crosslinking, and pyrolysis in an inert atmosphere at

1600°C. The green fibers with diameters of 10~25 µm

exhibited a ceramic yield of 46.4wt% at 1500 °C.

Hf-based ceramic fibers with diameters of 6~10 µm

were composed by HfC and HfB2 crystals. The above

precursor and Hf-based ceramic fibers hold great

Abstract

Oxychloride titanium oxide precursor material is one of

show that Oxychloride titanium oxide precursor has

good wettability to water and silicone oil. The

wettability has little to do with the bath temperature and

the pH of the solution. The contact angle of water on

oxychloride titanium oxide precursor surface does not

change greatly with the change of the bath temperature

and pH, ranging from 26.8°to 31.1°. Similarly, the

contact angle of silicone oil on the surface of the sample

Abstract

The microstructure evolution and flow stress behavior

of 2014 aluminum alloy during hot compression

deformation was studied by thermal simulation test on

Gleeble-1500 system at a deforming temperature range

from 410oC to 470oC and a strain rate range from

was obtained by 7800F scanning electron microscope.

The experimental results show that with the decrease of

strain rate and the increase of deformation temperature,

the elongated grain in the alloy is coarsened and partial

dynamic recrystallization occurs. The main softening

mechanism of the alloy is dynamic recovery, and the

flow stress of the alloy decreases with the increase of

the deformation temperature and the decrease of the

strain rate. After solution, the number of sub-grains

decrease, the number of recrystallization and its size

increase. As deformation energy is released during solid

solution treatment and promotes static recovery and the

multilateralism of the crystallization of the alloy during

Title: Active straining in tuning water splitting

Name: Kai Yan

Affiliation: Sun Yat-sen University


Abstract

We firstly present a study on the effect of externally

applied elastic strain on the catalytic activity of metal

films in the context of hydrogen evolution reaction

(HER) and oxygen evolution reaction. Thin metal films

supported on elastic substrates are uniaxially strained in

compression and tension while they participate in the

HER and their catalytic activity is measured through

shifts in the cyclic voltammograms.1,2 We show that

elastic strain tunes the catalytic activity in a controlled

and predictable way; for each metal considered here,

compressive and tensile strains have the opposite effect

on the catalytic activity; also, the changes in the

catalytic activity scale with the strain magnitude within

the range of strain values accessed in our experiments.

The experimental results show that Pt and Ni films

show increased HER under compressive strain; while

Cu's HER activity is retarded by compressive strain.

The opposite was observed under tensile strain. The

experimental observations are understood by

considering the influence of elastic strain on hydrogen

binding energy, which has been calculated through

density functional theory (DFT). Compressive strain

increases the hydrogen binding on Ni, shifting it

towards the volcano peak, while tensile strain has the

opposite effect. However, the same strains have the

opposite effect on Cu since it is located on the other side

of the volcano peak. We also report that one can gain

active control of electrocatalytic oxygen evolution

reaction (OER) on Ni3Fe thin films via externally

applied strains. The combination of theory and

experiment shows that elastic strain on the surface can

tune the OER activity in a predictable way that is

consistent with the d-band model. The OER

overpotential can be lowered by uniaxial tensions and

increased by compressions in a linear manner. By

isolating elastic strain from the ligand effect, this study

provides a better understanding of the processes that

control electrocatalytic activity towards HER as well as

OER and can guide design of strained core-shell

nano-particle catalysts.

Title: Electronic and optical properties of monolayer,

bilayer and trilayer black phosphorus

Name: Lushan Huang

Affiliation: China University of Mining and

Technology


Abstract

The electronic structure and optical properties of black

phosphorus (BP) from one to three layers are studied by

using the first-principles calculation method of density

functional theory (DFT). The results show that BP

always belongs to direct band gap. The energy band

gaps of monolayer black phosphorus (M-BP), bilayer

black phosphorus (B-BP) and trilayer black phosphorus

(T-BP) are 1.53 eV, 1.17 eV and 0.93 eV, respectively.

In order to explain the narrowing of the bandgap, we

found that the splitting of the band leads to a slight

change in the valence band, and the valence

band obviously shifts to the Fermi plane. P orbital plays

an important role in determining the electronic and

optical properties of BP. At the same time, we compared

the electronic structures of BP with graphene and

transition metal dichalogenides (TMDs). In addition,

we studied the optical

properties of BP under incident light of 0 ∼ 5 eV in a

very comprehensive way. The static dielectric functions

of M-BP, B-BP and T-BP are 1.51, 2.21 and 2.60,

respectively. With the increase of the number of layers,

BP shows the characteristics of metals and moves

toward the low energy region. Extinction coefficient k,

photoconductivity has a strong optical response to

ultraviolet light, and the response increases with the

number of layers. This provides a reference for

ultraviolet protection of BP and photoconductive

radiation detector. Moreover, we found that the effect of

incident light on the movement of BP segment can well

characterize the flexibility of BP. The variation on

optical properties of different layers of BP are

summarized, which provides a theoretical basis for the

adjustability of optical properties

Abstract

The concrete-encased steel (CES) composite columns

are made by structural steel sections being covered and

embedded in the concrete from all the perimeters of the

structural steel sections. The CES members and

lightweight concrete (LWC) are widely utilized in

structural engineering because of their various different

advantages. This study presents the finite element (FE)

analysis modeling of the lightweight aggregate concrete

encased steel (LACES) composite columns with

H-shaped steel section under eccentric loads, and the

accuracy of the proposed FE model was validated by

comparing the FE analysis result with previously

reported experimental data. From the analysis, it was

found that the proposed FE model can successfully

reflect the effects of changes in the engineering design

factors, and good agreements between the FE and test

results are found. Furthermore, using the FE modeling,

design factors, including the eccentricity value, LWAC

strength, confinement by increasing the tie stirrups

amounts, and column height, are studied. From the

results, it was found that the ultimate axial compressive

capacity of the LACES composite columns under

eccentric loading was negatively influenced by the

columns’ height increasing, but it was positively

influenced by the tie stirrups amount increasing.

Additionally, the ultimate axial compressive capacity of

the LACES composite column was significantly

influenced by the eccentricity value and the LWAC

strength.

A series of original research work has been

1. Based on the excellent photophysical and chemical

properties of plant phenolic compounds, the academic

ideas of photoconversion and utilization of plant

Title: Mechanical bottom-up nano-assembling and

nanomanipulation using shape memory alloy

nano-gripper

Name: Svetlana von Gratowski

Affiliation: Institute of Radio Engineering and

Electronics Russian Academy of Sciences


Abstract

Numerous nano-sized materials, such as nanoparticles

and nanostructures, in particular, 1-D and 2-D

nanomaterials: nanotubes, nanowires (NWs), grapheme

etc. in the past decades have been discovered and

intensively studied. They seem to demonstrate the

unique functional properties, allowing the design of a

large number of individual nanodevices based on them.

Recently, many studies have led to a wide range of

proofs of the concept of individual nanoscale devices

including NWs- and CNTs-, based nano-sensors, field

effect transistors, nanolasers etc. Such nanodevices

represent attractive building blocks for a hierarchical

assembly. A hierarchical collection of nanoscale /

mesoscale and macroscopic functional devices using

nanoscale building blocks offers many opportunities for

creating micro and macro devices based on alternative

―bottom-up‖ paradigm. There are 5 main steps in the

―bottom-up‖ approach for the production of

nanodevices: 1) to tailor (make) nanomaterials; 2) to

imprint (clean), passivate or varnish the surface of the

nanomaterial; 3) cut the nanomaterials into individual

components; 4) to make and to organize these items or

components into nanodevices; 5) to connect

(interconnect and unite), separate nanodevices together

in micro, -meso-and-macro world. The last 5th step is

still a challenge in modern nanotechnology. In the

present report the properties and prospective

applications of the new 3D nanomanipulation system

based on the smallest and fastest in the World shape

memory nanogrippers are discussed. This system is

proved to perform 3D manipulation of the real

nano-objects like nanotubes, nanowires, etc. This type

of nanomanipulation can be used for

nanomanufacturing nano/microdevices, using

alternative ―bottom-up‖ mechanical nano-assembly and

nanointegration. This breakthrough technology

pretends in many cases to compete the manufacturing

approaches based on very expensive currently available

―top down‖ silicon lithography.

Title: Study on Modification of Waste Rubber

Powder in Cement-based Composites Mixed with

Waste Rubber Powder

Name: Jian-mei Zhou

Affiliation: Inner Mongolia Universty of Science &

Technology


Abstract

In view of the disadvantage that the mechanical

properties of cement-based composites can be

significantly reduced by incorporating waste rubber

powder in situ, the surface modification methods of the

original rubber powder by coupling agent KH560,

sodium hydroxide, polyvinyl alcohol (PVA), methyl

hydroxyethyl cellulose ether (MHEC) and tetraethyl

orthosilicate (TEOS) as precursors were adopted

respectively. The modification of waste rubber powder

was studied by Change rate of mortar strength of

cement-based composite mortar mixed with waste

rubber powder. The results show that the hybrid

modification method using tetraethyl orthosilicate as

precursor has better effect. When 5 phr ethyl

orthosilicate is added, the compressive strength and

flexural strength of cement-based composite mortar can

be increased by 31.7% and 28%. Scanning electron

microscopy (SEM) results show that the surface of

waste rubber powder with good modification effect has

many protrusions and flake-like porous structures

which are beneficial to its bonding with cement-based

materials.

Abstract

With the continuous development of industry and the

increasing amount of car owner-ship, the air and water

quality has been seriously reduced. Especially some

volatile organic compounds (VOCs) in the air and

heavy metal ions in water, and other harmful substances.

VOCs can be categorized according to their chemical

structures: alkanes, aromatic hydrocarbons, esters,

aldehydes, alcohols, ethers, and amides. VOCs mainly

emitted from painting industry and automobile exhaust.

There are about 300 kinds of VOCs, most of which are

harmful to human and ecological environment. In high

concentrations, VOCs can be dangerous to human

health when they enter the lung or touch the skin. The

most common dangerous VOCs include benzene,

toluene and xylene. They are carcinogenic pollutants

that need to be monitored in the environment. On the

other hand, most common heavy metal ions in industrial

wastewater, including Zn2+, Cu2+, Hg2+, Pb2+, Co2+,

Ni2+ and so on also pose a serious threat to human

health and the safety of the ecological environment.

Heavy metals are non-biodegradable and easy to

accumulate in living organisms. Many heavy metal ions

are toxic or carcinogenic. As a cheap and high

performance adsorbent, fly ash (FA) is widely used to

adsorb harmful substances, including organic

compounds and heavy metal ions. In order to make full

use of physicochemical adsorption properties of FA, FA

was spun into multifunctional nanofiber membranes by

electrospinning technology to adsorb harmful VOC

gases such as benzene, toluene and xylene in air, and to

capture heavy metal ions (Pb2+ and Co2+) in water. In

order to improve the application value of nanofiber

membranes, a certain amount of silver nitrate was added

to the composite spinning solution, and finally the

multifunctional nanofiber membranes were

successfully fabricated via electrospinning, which had

adsorbed VOCs and heavy metal ions, and antibacterial

activity.

Title: Improvement of thermoelectric properties of

WSe2 by substitution in cationic and anionic

sublattices

Name: Galina Yakovleva

Affiliation: Nikolaev Institute of Inorganic Chemistry


Abstract

Thermoelectricity is an actively studied area in the field

of alternative energy. The essence of thermoelectricity

is the conversion of thermal energy into electrical

energy. For the characterization of thermoelectric

efficiency of materials use the parameter ZT= S2ζT/k,

where S – Seebeck coefficient, ζ – electrical

conductivity, k – thermal conductivity. Transition metal

dichalcogenides are the layered materials. Properties of

these materials determined by structure, namely, filling

the zone formed by d metal states. This fact determines

the properties of the material – semiconductor or metal.

So, WSe2 is p-type semiconductor with completely

filled d zone. In this work thermoelectric properties of

W0.98Nb0.02Se2-ySy (y=0.2, 0.3, 0.4, 0.5) and

W1-xNbxSe1.7S0.3 (x=0.02, 0.04, 0.06) were

investigated in the temperature range 77 -650 K. It was

found that substitution W on Nb increased the charge

carrier concentration by 4 orders of magnitude.

Wherein, substitution Se on S led to change the distance

between the valence band formed by the p states of

chalcogen and the narrow band formed by the d states of

metal. This fact explains the experimentally obtained

temperature dependence of the concentration

(decreasing the concentration with increase the

temperature). In total, we increased ZT from 0.002

(WSe2) to 0.26 (W0.98Nb0.02Se1.7S0.3).

Name: Chu Fengjian

Affiliation: Shandong University at Weihai


Abstract

In recent years, the new type of tumble waste dryer has

been promoted and developed. Heat generation through

phase transition is an environmental, friendly and

efficient heat transfer drying method. In order to know

under what conditions the water vapor has higher heat

transfer efficiency in the semi-circular cylinder and

more sufficient liquid phase transition, and under what

conditions the quantity of heat transferred can be

exactly controlled, we carried out relevant work. Based

on the analysis of two-phase heat transfer of rotating

body, a three-dimension model of garbage dryer is

established. Then, the commercial CFD software

ANSYS Fluent is used to simulate the two-phase flow

in the semi-circular cylinder, and the simulation

calculation is carried out. Finally, the theoretical

calculation results are verified by experiments.

Calculated by the simulation results analysis: according

to the industrial use of setting conditions, simulation

calculation results can achieve convergence, namely

water vapor through the pipe wall heat conduction.

Finally condense into liquid water, and to ensure that

the liquid cavity in the body has a higher volume

fraction, water vapor phase change rate is of more than

90%, the Nusselt number of the heat transfer surface is

60 to 300.

Abstract

Aims: Due to the extraordinary high thermal

conductivity and low heat capacity, carbon nanotube

(CNT) has shown a great potential as a thermo-acoustic

(TA) material recently. In this study, the frequcecy

response characteristics of TA emission from CNT are

explored in more depth for the purpose of guiding

investigation and development of the CNT based

nanothermophones.

Methods: By using the equations derived for acoustic

field of TA emission from point source and arbitrary

source based on a thermally-mechanically coupled

model, the frequency responses of the dot/wire/film TA

emission from CNT can be systemically analysed.

Results: The characteristics of sound pressure level

(SPL)-frequcecy response from near- to far field

changing with direction, distance, and size for all kinds

of nanothermophone are obtained and the nature of TA

sound wave is illustrated. Particularly, it is found that

there exists a fixed frequency cycle for frequency

response at a location in non-central axis direction

distant enough to TA source.

Conclusions: This work lay the foundation of TA

technique and would be of guilding significance for

developing new-type sound-emitting devices without

magnets and moving parts.

Abstract

There have been various experimental and numerical

studies on the muscle relaxation in skin tissue. The most

studies using numerical methods do not take into

account the unsteady-state conditions on the surface of

tissue by applying a constant heat flux or isothermal

condition at the surface of skin tissue. Therefore, in this

study, we propose the boundary condition equation of

heat transfer at the surface of tissue considering the

temperature characteristic over time in order to accurate

solution in thermal analysis of skin tissue. If the

temperature distribution on the surface of skin tissue is

regarded as semi-solid, the solution is as follows:

T(y,t)=T_i=(2q_0 "√(∝ t/π))/k exp(〖 -y〗^2/(4∝

t))-(q_0 "y)/k erfc(y/(2√(∝t))) (1) Where the erfc(η)

means a complementary error function. Since the

surface temperature can be obtained by substituting y=0

into Eq. (1), it can be expressed as follows:

T(y=0,t)=T_i=(2q_0 "√(∝t/π))/k (2) The heat flux (q0)

applied to the surface of tissue was 4.0 W/m2. The

thermal diffusivity (α) and thermal conductivity (k) of

skin tissue are 5.79 × 10-8 m2/s and 0.25 W/m2•K,

respectively. The theoretical value by the equation (2)

agrees well with the experimental value within the error

range of 2.5%. This is because the thermal diffusivity

and thermal conductivity of the skin tissue are so low. In

other words, the effect of physical properties is small

when the supply time of the heat source is increased.

Therefore, the theoretical equation (2) can be utilized as

a relation expression of the boundary condition on the

surface of skin tissue during the numerical analysis.

Title: Investigation of immersed boundary method

for wave-structure interaction using an internal

wave marker

Name: Der Chang Lo

Abstract

A computational study of a viscous incompressible

two-fluid model is included with a non-reflection

internal wave maker algorithm for the wave-structure

interaction problems. The source functions of

momentum equations include body force function,

internal wave maker function and absorbing wave layer

function. The body force function is used for the

treatment of immersed boundaries, the wave source

function is adopted for the generation of a target wave

in which the wave absorbing layer can prevent

absolutely the undesirable secondary wave reflections.

The level set method is employed to solve the

interfacial values between the water and air phases, so

that the surface elevation can be computed by solving

the level set equation. The numerical method based on

two-phase flow model is validated and extended to

cover the wave-structure interactions cases for (i) a

series of wave propagating in the water channel; (ii)

wave decomposition process over a trapezoid

breakwater, (iii) interaction between the periodic waves

and three different kinds of submerged structure in a

viscous fluid. The efficiency of the two-phase flow

model is demonstrated to simulate the hydrodynamic

force of wave acting on the structure by using an

immersed boundary method and internal wave maker.

Furthermore, an interfacial flow model with the

non-reflection internal wave maker can provide a robust

methodology for the applications of wave-structure

interaction simulation.

Title: Heat transfer of bilayer graphene based on

inter-facial rotation and methyl modification

Name: Bing Yang

Affiliation: Jiangsu University

Conference Guide

Abstract

Calculation method is critical to the reliability of the

results and conclusions of thermal property, and

interfacial thermal con-ductance (ITC) and thermal

conductivity in plane (TCIP) are also important to

effective heat transfer of graphene. In this work, the

Muller-Plathe method and the thermal relaxation

method are compared and analyzed. Then, the ITC and

TCIP of twisted bilayer graphene and bilayer graphene

with methyl are calculated. For the two methods, the

ITCs near the Debye temperature are basically the same,

but when the temperature is less than the Debye

temperature, the ITCs obtained by the thermal

relaxation method are lower than that calculated by the

Muller-Plathe method after quantum correction, for the

reason that the quantum correction does not take into

account the strong dependence of phonon modes on

temperature at low temperatures. For twisted bilayer

graphene, the result shows that the twisted angle can

adjust the ITC. The ITC of AA stack (0 degree) is

57.1% higher than that of AB stack (60 degree), which

is consistent with the interaction energy and phonon

matching between interfaces. For bilayer graphene with

methyl, to verify the correctness of the potential

parameters, the electron density difference and the

inter-atomic spacing are calculated by density

functional theory. Then the ITC and TCIP of bilayer

graphene with different number of methyl are

calculated. It is found that with the increase of the

methyl, the inter-layer spacing increases continuously,

and the interfacial interaction energy decreases

constantly, which lead to the reduction of the ITC. In

addition, the TCIP also shows a downward trend for the

increase of methyl. This work has important guiding

significance for theoretical calculation of ITC and

application of thermal properties of graphene.

Abstract

Tether-net is a new active removal technology for space

debris, and its deployment and capture have attracted

considerable attention. This study focuses on the

dynamics and simulation of self-collision of tether-net.

First, the mass-spring-damper method is used to model

tether-net and a line–line self-collision detection

algorithm is proposed according to the geometric

characteristics of tether-net. Thereafter, combined with

the nonlinear collision model, the self-collision process

of tether-net is studied. The simulation of the close-up

of a net with a target is executed to show the difference

between considering and not considering the

self-collision of tether-net. Results reveal that the

capture process of tether-net with consideration for

self-collision is different from the one without

self-collision, especially after the corners of the net

begin to contact each other.

This presentation deals with fully resolved simulations

of particulate flows with conjugate heat transfer on the

particle-fluid interface. We performed two-dimensional

ones in many aspects, such as the Grashof number (Gr)

delineation of the regime of particle motion, the

terminal velocity as a function of Gr, and the amount of

particle’s migration off the centerline.

method is used to simulate the aerodynamic

characteristics of a simplified gas filter. The inertial and

viscosity parameters of porous media are solved by

Forchheimer equation. The three-dimensional N-S

equation and the modified low Reynolds number k-ε

turbulence model are adopted to analyze the influence

of the explosion-proof plate on the gas filter’s

aerodynamic characteristics. The results showed that

the air age in the upstream of the activated carbon plates

was small, which easily caused the rapid penetration of

the Poisonous gas. And in the downstream and around

of the activated carbon plates, the air age is larger,

formed dead zone, the utilization rate of activated

carbon is lower. The explosion-proof plate increases the

pressure drop of the gas filter, the air age distribution in

the filter layer is more uniform and the utilization rate of

filter paper is improved. However, the explosion-proof

Abstract

Cavitation is a complex flow phenomenon including

unsteady characteristics, turbulence, gas-liquid

two-phase flow. In this paper, OpenFOAM is used to

simulate and compare different cavitation models.

Three kinds of models in OpenFOAM -- Merkle model,

Kunz model and Schnerr-Sauer model are compared in

this paper. Considering the influence of vapor-liquid

mixing density on turbulent viscous coefficient, the SST

k-Omega model is modified on OpenFOAM to increase

the reliability of calculation in this paper. The modified

SST k-omega turbulence model is added to the

InterPhaseChangeFoam solver to simulate the

two-dimensional cavitation flow of Clark-Y hydrofoil

with three cavitation models. The hydrodynamic

performance including lift coefficient, drag coefficient

and cavitation shape of two-dimensional cavitation

flow around Clark-Y hydrofoil is investigated. Through

the comparison of the numerical results and the

experimental results, it is found that the Schnerr-Sauer

model can get more accurate results compared with the

other two models. Comparing the experimental data

with the numerical simulation results of Clark-Y

hydrofoil cavitation characteristics, the reliability of

numerical simulation of Clark-Y hydrofoil cavitation

flow using Schnerr-Sauer model in OpenFOAM is

verified.
