Advanced large scale colloidal lithography for sub-100 nm direct and indirect nanostructuring: application to silicon and metals

Kadiri H., Faustini M., Turover D., Grosso D., Gokarna A., Lerondel G., Université de Technologie de Troyes, FR

Actually nano-sphere lithography is a great technique to fabricate structures at large scale, therefore using self-assembly as a bottom-up approach nano scale materials. In this study, combining Reactive Ion Etching(RIE) and polystyrene(PS) nano-sphere lithography we [...]

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 [...]

On the dynamic contact angle in spontaneous capillary flow

Berthier J., Gosselin D., Delapierre G., CEA-LETI, FR

Capillary actuation of fluids is an interesting solution when the gravitational forces are small: this is the case in space , or in microfluidic systems where gravity is negligible. The onset of spontaneous capillary flow [...]

Recent advances in capillary microflows for point-of-care and home-care devices

Berthier J., Gosselin D., Huet M., Cubizolles M., Delapierre G., CEA/LETI/MINATEC, FR

Biotechnology has been recently seeing fundamental evolutions: first, a clear shift towards biological applications; second a trend towards the design and fabrication of portable devices; third the choice of inexpensive materials such as plastic or [...]

Determination of the bi-substrate kinetic coefficients for the beta-D-glucose- NAD-GDH enzymatic reaction

Berthier J., Cubizolles M., Laurent P., Pouteau P., Poher V., Cosnier M.L., CEA, FR

Colorimetric detection of glucose in sample liquids such as human plasma is made by using enzymatic reactions. In the multi reactional scheme, the first enzymatic reaction is determinant. Either glucose oxidase (GOX) or glucose dehydrogenase [...]

Biological Decontamination of Radionuclides in Industrial and Environmental Water Using a New Highly Radioresistant Microalga

Rivasseau C., de Gouvion Saint Cyr D., Atteia A., Gromova M., Farhi E., Commissariat à l’Energie Atomique, FR

Nuclear energy technologies generate radioactive and chemically toxic compounds including mainly carbon-14 and radioactive metals. Treatment processes rely on physico-chemical methods, which, though efficient and robust, do not completely remove carbon-14 and are not adapted [...]

Nano-oxyhydride catalysts for hydrogen production from bioethanol at room temperature

Jalowiecki-Duhamel L., CNRS, FR

H2 economy could be clean and sustainable only if it is produced from renewable sources and bioethanol obtained through biomass is a promising renewable source of hydrogen. Well tuning the preparation, formulation and conditions applied, [...]
