Rechargeable Lithium-ion Batteries For Wireless Smart Designs

Mourzagh D., Rouault H., Jouanneau S., Daniel L., Chami M., Moreau G., Fusalba F., CEA-Grenoble, FR

Wireless communication is today considered as a disruptive technology. Indeed, even if wired systems can easily achieve 100% of reliability, it induces high amount of wiring, which has non negligible impact on the mass and [...]

Understanding Ru/CNT interactions: A rational design of Ru nanocatalysts

Machado B.F., Oubenali M., Axet M.R., Nguyen T.T., Tunckol M., Girleanu M., Ersen O., Gerber I.C., Serp P., Laboratory of Coordination Chemistry, FR

We report a detailed study on the nature of the ruthenium–carbon nanotube (Ru/CNT) interface in catalysts prepared from neutral Ru(0) organometallic precursors. Experimental data combined with density functional theory calculations allowed to conclude that both [...]

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

Martinez-Prieto L.M., Philippot K., Chaudret B., CNRS, FR

The development of more active and/or selective catalysts for industrial application of the Fischer Tropsch Synthesis (FTS) process is still an ongoing field of research.In this context, Ru nanoparticles that are expected to provide more [...]

Record resistivity for in-situ grown horizontal carbon nanotubes interconnects

Dijon J., Ramos R., Fournier A., Fournier H., Le Poche H., Fournier A., Fournier H., Okuno H., Simonato J-P, CEA-Liten, FR

Carbon in the form of nanotubes (CNTs) and graphene is the only known material that can replace copper in integrated circuits to carry the high current densities associated with advanced interconnects. Its implementation is however [...]

Nanoemulsion with tuneable lipid shell dedicated to targeted delivery of small and biomacro- molecules

Couffin A.C., Bruniaux J., Courant T., Hoang A., Martin C., Fournier A., Mittler F., Texier I., Sulpice E., Auzély-Velty R., Gidrol X., Navarro F., Commissariat à l'Energie Atomique et aux Energies Alternatives, FR

Lipid nanocarriers are considered as suitable carriers to formulate lipophilic drugs, transport them and also deliver more specifically at appropriate biological sites. Based on oil-in-water template emulsion, we have been developing nanodroplets as drug or [...]

Carbon Nanotube Matrices for implantable Biofuel Cell design

Holzinger M., Le Goff A., Cosnier S., CNRS - University of Grenoble, FR

Glucose biofuel cells are promising candidates to supply implanted electronic devices by converting the chemical energy of glucose, present in body fluids, into electric power. Before such biofuel cells can become realistic alternatives compared to [...]

On-line production of polyelectrolyte coating on monodisperse alginate beads in an integrated microfluidic cartridge

Laffite G., Forvi E., Hadji C., Authesserre C., Alessio M., Costa G., Boizot F., Rivera F., CEA-LETI, FR

Continuous flow microfluidic devices have appeared to be a promising technology to automatise Polyelectrolytes multilayers (PEMs) coating on microbeads with repeatable and reliable results. However, no microfluidic devices have demonstrated PEMs coating on hydrogel beads [...]

Open-Surface Microfluidics

Berthier J., Brakke K.A., Furlani E.P., Karampelas I.H., Delapierre G., CEA-LETI, FR

The developments of open-surface microfluidics (OSM) for biotechnology are recent, and motivated by the development of point-of-care (POC) and home-care systems. The advantages of capillary systems are (1) low cost due to easy and fast [...]

On the velocity of spontaneous capillary flows in confined and open microchannels

Berthier J., Villard N., Pudda C., Boizot F., Nonglaton G., Costa G., Fontelaye C., Delapierre G., CEA-LETI, FR

In biotechnology and biology, conventional microfluidic systems using fluids moved by pumps, syringe or electric means are not the best solutions when portability and low-cost are an issue. Capillary-based systems fulfill the requirements for POC [...]
