SRD-MD modelling of hydrodynamic interactions in colloidal systems: playing between computational cost and resolution

Laganapan A.M.K., Videcoq A., Cerbelaud M., Mouas M., Bienia M., Ferrando R., Science of Ceramic Processing and Surface Treatments (SPCTS), FR

A ubiquitous problem that has always been a subject of intensive research is the role played by hydrodynamic interactions (HI’s) in several fundamental problems in colloid rheology and aggregation kinetics. However, the high computational demand [...]

Simulation of the suspension structure for the improve of colloidal processes

Cerbelaud M., Videcoq A., Lestriez B., Guyomard D., Ferrando R., CNRS, FR

Colloidal processes are used in many fields of applications to produce multi-material components with specific microstructures. Here, controlling the structure of colloidal suspensions is crucial in order to reliably adapt the suspension rheology to the [...]

Copper/CNT composite materials with enhance mechanical and termal properties

Silvain J.F., Vallet G.M., Dunand M., ICMCB-CNRS, FR

With their huge mechanical, thermal and electrical properties, carbon nanotubes are good candidates as reinforcements in material composites. However, such materials are not easy to elaborate and several problems occurred such as the dispersion of [...]

Non-conductive ferromagnets based on core double-shell nanocomposites for radio-electric applications

Takacs H., Viala B., Hermán V., Tortai J.-H., Duclairoir F., Alarcon Ramos J., Jouneau P.-H., Okuno H., Tallec G., CEA, FR

We report a novel flexible nanotechnology for consumer product engineering as a complementary approach from solid-state manufacturing techniques based on metallic nanoparticles and graphene chemistries. We describe two chemical routes for producing closely-packed disordered assemblies [...]

Ionic liquid: an innovative medium for nanofabrication

Darwich W., Santini C.C., Gaillard F., Haumesser P.-H., université de lyon 1, CNRS UMR 5265, FR

Porous silicon (PSi) has been attracting a great attention as a breakthrough material with exceptional characteristics for microelectronics, layer transfer technology, solar and fuel cells, biomedicine, etc. Its properties can be modified by in introducing [...]

Preparation of electrical conductive polymer/graphite oxide composites through the functionalization of graphite oxide sheets

Beyou E., Guimont A., Cassagnau P., Martin G., Sonntag P., Lyon1 University, FR

The preparation of polyethylene/graphite oxide composites exhibiting rheological and electrical percolation thresholds was accomplished by radical addition reactions onto the unsaturated system of graphite oxide sheets through the use of pentadecane and polyethylene in presence [...]

Understanding 2D atomically thin and layered materials beyond graphene using a novel X-ray microscope

Avila J., Chen C., Lorcy S., C. Asensio M., Synchrotron SOLEIL, FR

Research and development of atomically thin, 2D materials from a broad range of layered compounds beyond graphene have sparked enormous scientific interest. The main goal in this field is to disclose the implication of heterogeneities [...]

Polymer nanocomposites reinforced with nanoparticles extracted from renewable resources

Dufresne A., Grenoble institute of technology, FR

There has been an explosion of interest in the use of biomass as a source of renewable energy and materials. One focus of this activity has followed from the recognition that, by suitable chemical and [...]

Organometallic Ruthenium Nanoparticles as a Model of study for Fischer-Tropsch Synthesis Reaction
