Iron carbide and iron-cobalt nanoparticles for magnetically induced CO2 hydrogenation

The development of renewable energies is an essential requirement for a future sustainable world. However, both solar and wind power energies are intermittent and raise questions regarding their real efficiency since energy production can oscillate between shortage and over-production. The power-to-gas approach developed in particular in Germany is an alternative to the smart grid and local electrical storage. It transforms CO2 into methane using hydrogen produced by electrolysis. However, to-date large production units are required which take a long time to start and stop and are therefore not well fitted to intermittence.

One idea to circumvent this problem is to use magnetic and catalytic nanopar-ticles which could be heated by magnetic induction. Thus magnetic heating is instantaneous, in principle the best way to transform electrical energy into heat and therefore well adapted to intermittence. For this purpose we have developed in Toulouse a new generation of iron carbide nanoparticles of unprecedented heating power. The particles are prepared by carbidization of preformed mono-disperse Fe(0) nanoparticles under a CO/H2 atmosphere at 150°C. They consist essentially of crystalline Fe2.2C, display a SAR (heating power) of up to 3.3 kW/g and are able to hydrogenate CO2 into methane in a flow reactor after ad-dition of a catalytic Ru or Ni layer and excitation by an alternating magnetic field

The lecture will present the synthesis of the particles, their magnetic proper-ties, their surface modification to deposit a catalytic layer and the develop-ment of a flow reactor for selective hydrogenation of CO2 into methane and the developments that are possible using magnetic nanoparticles in catalysis.

Topology and physics: magnetic skyrmions, recent advances

Magnetic skyrmions are small local spin configurations stabilized by the protection due to their topology. In most cases, they are induced by chiral interactions between atomic spins existing in non-centro-symmetric magnetic compounds or in thin films in which inversion symmetry broken by the presence of an interface. The skyrmions can be extremely small with diameters in the nm range and, importantly, they behave as quasi-particles that can be moved as “nanoballs”, making them suitable for “abacus”-type applications in information storage, logic or communication technologies.

Up to the last years, skyrmions were observed only at low temperature (and in most cases under large applied fields) but an important effort of research has been recently devoted to find thin films and multilayered structures in which skyrmions are now stabilized above room temperature (RT). It has also been found that skyrmions can be easily created, detected and driven at large speed by electrical currents. The talk focuses on these recent advances paving the road to the implementation of skyrmions into devices [1].

TiO2 nanotubes: Formation, Properties and Applications

Self-organizing anodization has in the last 30 years been successfully employed to fabricate not only ordered porous alumina layers, but in addition other aligned nanoporous and nanotubular materials including semiconductors and functional oxides such as titania.TiO2 nanomaterials have attracted tremendous scientific and technological in-terest. Main research directions using TiO2 in functional applications is the use in Grätzel type solar cells, biomedical applications or the use in photocatalysis, e.g. for the direct splitting of water into H2 and O2 to generate the potential fuel of the future, hydrogen.

Over the past decades, various 1D and highly defined TiO2 morphologies were explored for the replacement of nanoparticle networks and were found in many cases far superior to nanoparticles or their assemblies. Nanotubes grown by self-organizing anodic oxidation are aligned perpendicular and direc-tly back-contacted to the conductive substrates and therefore can be directly used as functional electrodes (e.g. photo-anodes).Self-ordered nanotube formation is not limited to pure titanium substrates but can also be formed on a wide range of elements and alloys. This allows the fa-brication of advanced and doped morphologies. The presentation will focus on these highly ordered nanotube arrays of TiO2 and discuss most recent progress in synthesis, modification and applications.

Molecular Systems Engineering with DNA

Programmable self-assembly with DNA origami allows creating custom-shaped nanoscale objects. Through this capacity, DNA origami enables constructing custom instruments to perform precision measurements of molecular interac-tions and structure, with enhanced control over positioning, orientating and manipulating the molecules under study. In my presentation I will report about some of our progress toward constructing devices with greater complexity, more sophisticated functionalities, and about making large quantities (1-3). If time permits, I will also discuss a series of measurements in which we used cus-tom-made DNA nanotools to control distances between molecules with atomic precision (4), and to measure weak stacking forces between basepairs (5) and between pairs of nucleosomes (6) on the single particle level.

Revisiting blackbody radiation at nanoscale

Thermal radiation is generally assumed to be both spatially and temporally in-coherent. Radiative heat flux is often considered to have an upper bound given by blackbody radiation. In this talk, we review advances in the last 15 years that challenge these ideas at the nanoscale.

It is now possible to design incandescent sources which are directional and spectrally selective by taking advantage of surface waves. We also report the discovery of the enhancement by several orders of magnitude of the energy density close to an interface at a particular frequency as well as the enhance-ment of the radiative flux between two interfaces when surface phonon polari-tons can be excited. These results lead to the design of a novel class of infrared incandescent sources with potential applications in spectroscopy, gas detec-tion and thermophotovoltaic energy conversion.

Patrick Chaskiel is Full Professor of Social Communication Sciences at Tou-louse University (France) since 1993. He is member of the Certop lab (Centre d’Etudes et de Recherches Travail, Organisation, Pouvoir), jointly operated by the CNRS, Université Toulouse Jean Jaurès and Université Paul Sabatier-Tou-louse 3.

He has been working on the technological risks topic for many years. He was in charge of the risks program in the “Maison des Sciences de l’Homme et de la Société” (CNRS and University of Toulouse) until 2017. He has been responsible of, or contributed to, several research operations supported by the Minister of Ecology, the Anses, the CNRS, the Stae Foundation, and the region of Occitanie. He was or is member of working groups on the risks of nanos (Anses) or on the labelling for nanoproducts (Minister of Ecology). He is presently member of the “Comité d’évaluation scientifique Innovation-Travail” 2018, of the French ANR.

Since the beginning of the ambitious policies of nanotechnologies and nanos-ciences, controversies on nanos have developed in many countries. This is not surprising, owing to previous ecological trends focused on risks and the publi-cly displayed immoderate ambitions of these policies, as summarized by the National Nanotechnology Initiative. Facing these disputes, scientific or political institutions have classically pro-posed to improve communication between stakeholders, particularly by insis-ting on the necessity of adopting a benefits/risks approach.

23

However, to be sustainable, this approach should be somewhat theorized, but also has to be adjusted to the specificity of nanos, particularly because risks are almost unknown, and real benefits are mainly to be determined yet.

The purpose of this lecture is to examine the reasons why the notion of “bene-fits from nanos” is much more complex than generally supposed and how this complexity could be positively used in the perspective of combining benefits and precaution.

Cotranscriptional Folding of RNA Nanostructures and Devices

RNA nanotechnology has the great potential to allow us to produce well-de-fined nanostructures and devices inside cells and thus open up a wide range of design opportunities in synthetic biology. To achieve this goal we need to understand the design principles of geometry, folding kinetics and topology that will allow us to genetically encode well-defined RNA nanostructures that self-assemble during the transcription process. We have recently introduced the single-stranded RNA origami method and validated the architecture by transcribing RNA tiles that assemble into lattices of different geometries. I will introduce new software tools that allow interactive design of RNA origami structures using a library of functional modules and new sequence design ap-proaches that allow large structures to be designed. In addition, I will show our latest progress in developing larger three-dimensional RNA origami structures and functional RNA nanodevices with applications in biosensing and diagnos-tics.

Dr. Alessandro Coat graduated from the University of Catania and Padova (Ita-ly) where he obtained a PhD in Material Science on semiconductor heteros-tructures. He then worked as a post-doctoral fellow at LURE Synchrotron and is now a scientist at Synchrotron SOLEIL where he is in charge of the Surfaces and Interfaces X-ray Scattering (SixS) beamline, dedicated to the study of surfaces, interfaces and nano-objects by grazing incidence X-ray diffraction and small angle scattering and X ray reflectivity. He works now with the SixS beamline staff on metallic nanostructured surfaces and nano-objects devoted to spin-tronics or catalytic applications by following the materials structural changes in operando conditions.

Grazing incidence X-ray scattering techniques are well adapted for the studies of supported nanoparticles under gas environments.

26

These techniques are available at SixS beamline at Synchrotron SOLEIL, which presents two end stations: the first one dedicated to UHV studies (allowing gases exposures ranging from 10-10 to 10-5 mbar) and the second one is equipped with a flow reactor (XCAT) where a pressure of 2 bars can be reached.

Two examples concerning the evolution of bimetallic nanoparticles (NPs) in the presence of reactive gases will be presented. In both the examples the reaction considered is the CO oxidation, which is a key reaction for catalysis process [1].

The first experiment concerns the study of the evolution of Au-Cu NPs sup-ported on TiO2(110) during the reaction [2]. GIXD measurements show that, in spite of being alloyed, NPs present a Cu segregation to their surface upon oxygen exposure at room temperature. This process is reversible upon annea-ling at 300°C. Reorientation and/or recrystallization of the smallest NPs is also observed.

The second example concerns Au-Pd NPs synthesized by micelle nanolitho-graphy, a technique allowing to yield a very sharp size distribution and a well controlled composition of the NPs. Spin-coating metal-loaded micelles on SiOx/Si(001) are exposed to oxygen or hydrogen plasma in order to remove the polymer and form the nanoparticles. The influence of oxygen and hydrogen plasma treatment on the reactivity of the particles is clearly evidenced.

Recent Advances in PEM Fuel Cell Materials with Improved Durability and Lower Cost

Proton exchange membrane fuel cells require disruptive solutions in materials in order to address the remaining challenges in increasing durability and redu-cing costs, and meet the expectations required for real market introduction. These include very thin polymer membranes but with chemical and mechanical stability, replacing platinum at the electrodes, without compromising activity or stability, alternative support materials to carbon but with similar electrical characteristics. Moreover, increasing the power density needs optimisation of all interfaces to reduce resistive contributions. We will describe some origi-nal approaches to PEM fuel cell materials including new architectures for fuel cell electrodes, membranes and their reinforcement and chemical stabilisation components, membrane electrode assemblies, and reducing or replacing plati-num with non noble metal catalysts.

Light-Matter coupling in two dimensional materials

Monolayers of transition metal dichalcogenides (TMDC) are an emergent class of nanoscale materials, which are close-to-ideal to study excitonic effects, spin-related phenomena and fundamental light matter coupling in condensed matter systems. Their strongly pronounced exciton and trion resonances make them highly suitable to study advanced light-matter interaction phenomena, such as strong coupling between excitons and photons, even at room tempe-rature. In this talk, I will discuss the formation of exciton-polaritons in microcavity sys-tems with embedded TMDC monolayers. Polaritonic modes manifest in their characteristic dispersion relation of the emitted light from such a microcavity system. Furthermore, I address peculiarities associated with the polarization of the emitted radiation from such a strongly coupled system, where effects of spin-valley coupling are retained even up to room temperature.

François TREUSSART (48 years old; 64 publications in peer-reviewed journals; h-index=27) is a professor at Physics Department of ENS Paris-Saclay, since Oc-tober 2006 and head of the “BioPhotonics” team at Laboratoire Aimé Cotton. He was trained in quantum and Laser optics. He defended his PhD (1997) at Laboratoire Kastler Brossel (ENS and Univ. Pierre & Marie-Curie, Paris) under the supervision of Prof. Serge HAROCHE. His expertise is in single emitters and nanocrystals spectroscopy. He started to use color centers in diamond in 2003, for the production of single-photon-on-demand and shifted in 2006 to bio-imaging applications of fluorescent nanodiamonds (fND). In collaboration with Prof. Michel SIMONNEAU, a molecular geneticist, he recently developed a fND-tracking assay sensitive enough to detect fine modifications of intraneu-ronal transport induced by genetic risk factors of neuropsychiatric diseases.

Intraneuronal transport abnormalities revealed by fluorescent nanodia-monds tracking

Brain diseases such as autism and Alzheimer’s disease (each inflicting >1% of the world population) involves a large network of genes displaying subt-le changes in their expression Abnormalities in intraneuronal transport have been linked to genetic risk factors found in patients, suggesting the relevance of measuring this key biological process.

We will also show that this nanoparticle tracking based-approach applies to multiphoton imaging in neuronal culture too, despite the need for raster scan-ning of the focused excitation beam, thanks to the use of nanocrystals with large second order optical nonlinearities. These results should allow the exten-sion of our assay to the measurement of intracellular transport in neuron of organotypic cultures, brain slices and even of the cortex in living mouse.

Fluorescent nanodiamonds (shown in red in (c)) were used to measure the velocity of molecular transport in mouse neurons. The method developed is sufficiently accurate to detect an increase in velocity (d) when an increase in concentration of only 30% of an enzyme (Mark1) is reproduced in some transgenic mice (a), i.e. in L8 lines but not in L38 as shown in the overproduction quantification graph (b). This overproduction of Mark1 is the same as the one found in the brains of autistic patients after their death.S. Haziza et al., Nature Nanotechnology 12, 322 (2017).

Mild chemistry on graphene interfaces : a first-principles investigationin vacuum and in water

Graphene is an attractive candidate for carbon-based electronic devices. However the absence of band gap is a major hindrance for such applications. So there is a need to develop routes for engineering the band gap via chemi-cal covalent functionalizations. The challenge resides in the fact that graphene is assumed to be chemically inert. Hence covalent functionalization requires drastic conditions that affect the ideality of pristine graphene.

In this talk I will first question whether cycloaddition reactions between por-phyrins and graphene prototyping mild chemistry is a viable route.

Based on an extensive static DFT study we unveiled the necessity of pre-activa-ting the graphene layer via epitaxy on a proper metallic substrate. In particular we showed that the feasibility of the cycloaddition between an iron-porphine and epitaxial graphene strongly depends on the nature of the metal, Ir being the most active support as compared to Re and Cu. [1] Such predictive cycload-dition process has been realized at the single-molecule level by STM-induced chemistry on low-coverage iron phthalocyanine (FePc) molecules adsorbed on graphene on Ir. [2]

Seconds I will question the chemical inertness of graphene in a water media. Recent nanofluidic experiments have demonstrated the significant charging capacity of carbon nanotubes of diameters ranging from 7nm to 70 nm in alk-aline water for promising applications in « blue energy ». [3] Static DFT calcu-lations in vacuum and implicit water contradict the charging via chemisorption of hydroxide ions on single layer graphene. [4]. However our recent AIMD si-mulations with explicit water solvent permit to reconcile the atomistic quan-tum simulations with the experiments.

Plasmonic nanoantennas to explore nanoscale heterogeneities in living cell membranes

Plasmonic-based nanophotonic structures offer new opportunities to study single fluorescent molecules as they can confine electric fields in nanoscale hotspots with spatial dimensions comparable to single molecules. Here, we show planar plasmonic nanogap antenna arrays to study the diffusion characteristics of phosphoethanolamine (PE) and sphingomyelin (SM) in living cell membranes. The enhanced electric fields in nanoscale probe areas yield a sub-diffraction spatial resolution together with a high signal to noise ratio thanks to the phenomenon of plasmonic-enhanced fluorescence emission. Our findings provide a better understanding of the spatiotemporal and hete-rogeneous organization of living cell membranes at the nanoscale. The pro-posed technique is fully biocompatible and thus provides various opportunities in biophysics and live cell research.

Solution-processed Photoelectrodes for solar fuel production To transition our energy economy into one that is fully sustainable and not de-pendent on fossil fuels, developing an economically viable “artificial photosyn-thetic” device for the overall storage of solar energy as chemical energy is an urgent goal. Using solar energy to drive the electrochemical production of fuels (e.g. the splitting of water into molecular hydrogen and oxygen) is a promising technology in this regard. High-efficiency solar-to-fuel energy conversion can be directly achieved using a photoelectrochemical (PEC) device consisting of an n-type photoanode in tandem with a p-type photocathode. However, the development of stable and inexpensive photoelectrodes are needed to make PEC devices economically viable.

In this presentation our laboratory’s progress in the development of economi-cally-prepared, high performance photoelectrodes will be discussed along with the application toward overall PEC water splitting tandem cells. Specifically, how the use of scalable solution-processing techniques (e.g. colloidal proces-sing of nanoparticles or sol-gels) leads to limitations in charge transport and charge transfer in the resulting thin-film photoelectrodes will be examined. Strategies to overcome these limitations using chemical innovations such as using charge extraction buffer layers, catalysts, annealing/doping and nano-particle self-assembly will be additionally presented. Materials of interest are delafossite CuFeO2 [1] CIGS [2], 2D-layered WSe2 [3], and semiconducting car-bon-based materials [4].

A NEW ORGANOMETALLIC ROUTE FOR LOW TEMPERATURE ALD/CVD OF ATOMICALLY-THIN TMD LAYERS (MOS2, WS2) ON 2D SUPPORT)

Since 2010, layered transition metal dichalcogenides (TMDs) such as group (IV) to (VI) metal disulfides have emerged as a new class of 2D materials possessing a wide range of interesting electronic properties. Among them, MoS2 and WS2 have been widely studied as 2D semiconductors possessing a direct bandgap, and proof-of-concept-de-vices such as FET, phototransistors, piezoelectric cells or chemical sensors were suc-cessfully built from mechanically-exfoliated MoS2 or WS2 monolayers. In order to de-velop new electronic devices based on these new 2D materials, few synthesis methods meet industrial requirements in term of uniformity, integration potential, and compa-tibility with existing production tools.

In this context, we report here ALD/MLD and CVD methods (Atomic/Molecular Layer Deposition method, see Scheme, and Chemical Vapour Deposition), based on or-ganometallic chemistry applied to the solid surface of the wafer, for the growth of 2D MoS2[1] and WS2[2] crystals . This contribution will present the characterization of the 2D layers and the proposed surface coordination chemistry mechanism at hand obtaine with model studie on 3D silica beads.

Photonic Crystals for the Control of Absorption and Emission in Solar CellsPhotonic crystals and related structures offer great potentialities for thin layer solar cells, but also or for next generation photovoltaic devices using wavelen-gth conversion. In this communication, we will present advanced designs and light control strategies, looking for the best compromise between perfectly ordered [1] and perturbated [2] nanopatterns.

In particular, we will compare the characteristics of fully optimized square lat-tices of holes with pseudo-disordered patterns based on the periodic replica-tion of a supercell in which the holes positions are shifted. Theoretical predic-tions and experimental results will illustrate that in the case of well controlled perturbations, the absorption at long wavelengths can be optimized. We will then discuss on the integration of such patterns in real-world thin film silicon solar cells. We will also introduce longer term potentialities related to wavelength conver-sion in solar cells. We will show how to control the efficiency of the down shif-ting process by the use of photonic crystals combined to optically active mate-rials like rare earth films on the top of solar cells [3].

Multi-functionalization of magnetic nanoparticles for biosensing applications

Magnetic nanoparticles are attracting considerable attention in biosensing due to their high surface-to-volume ratio and their unique superparamagnetic properties. They are particularly useful to isolate biological targets in a com-plex medium and to bring them close to the biosensor transducer in order to amplify the detected signal. To reach these objectives, the surface of magne-tic nanoparticles must be modified with specific bioreceptors and signalling molecules used for detection. Therefore, multi-functionalization is general-ly required. This presentation will focus on two main examples. The first one concerns magnetic glyconanoparticles for the extraction of lectins, that are specific proteins found on the surface of Pseudomonas Aeruginosa bacteria. The second example is about dual-functionalized magnetic nanoparticles exhi-biting an electrochemical signal and able to capture platelets antigens.
