Silver Nanowires for Plasmon Induced Enhancement of Optical Absorption in Thin-Film Silicon Solar Cells

Mailhes R., Institut des Nanotechnologies de Lyon (INL), FR

Plasmonic effects for photovoltaics are investigated through this communication. We present here an innovative design with integrated silver nanocylinders located at the rear side of a thin crystalline silicon cell. Numerical simulations (FDTD) show that [...]

Cationic lipid nanoemulsions for RNAi screening

Bruniaux J., Sulpice E., Mittler F., Texier I., Gidrol X., Navarro F.P., CEA/LETI/MINATEC, FR

Since the discovery of RNA interference, many efforts have been made to broaden perspectives of small interfering RNA (siRNA) in research and clinical work. siRNA shows a specific and effective gene silencing activity through a [...]

Lipid nanoparticles for enhancing immune responses to protein antigens

Courant T., Reynaud H.L., Hoang A., Villiers C., Mittler F., Texier I., Marche P.N., Navarro F.P., CEA/LETI/MINATEC, FR

In the near future, novel vaccines will be needed, particularly nanoparticles-based vaccine formulations for figthing problematic infectious diseases like tuberculosis, AIDS/ HIV or malaria and also cancers. Here, we described the development of versatile chemical [...]

Novel sensing device based on potentiometric measurement for the detection of lithium

Merzouk S., Zine N., Tahajanan M., Agouzoul M., Bausells J., Teixidor F., Jaffrezic-Renault N., Errachid A., Institut des Sciences Analytiques, FR

The therapy of manic depressive psychosis with lithium salts requires periodic measurements of the Li concentration in whole blood, plasma, urine or serum. The analysis is difficult because of the low lithium concentration compared to [...]

Rechargeable Lithium-ion Batteries For Wireless Smart Designs

Mourzagh D., Daniel L., Chami M., Rouault H., Fusalba F., CEA, 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 [...]

Role of special sites on the selective activation of C-H and C-C bonds by nanoparticles: Ru13 as a test-case

Mercy M., del Rosal I., Poteau R., LPCNO (IRSAMC), Université de Toulouse, FR

It is now well known that size and shape of nanocatalysts affect their catalytic properties. As a consequence, nanocatalysis has recently emerged as a major new field, with experimentalists now on the edge to rationally [...]

A Surface-Potential-Based Compact Model of AlGaN/GaN HEMTs Power Transistors

Martin P., Hahe R., Lucci L., CEA-LETI, FR

A new physics based compact model for III-nitride HEMTs developed for SPICE circuit simulation is presented. The HSP model (acronym for HEMT Surface-Potential model) follows a physical approach for power devices modeling, as it was [...]

From Microfluidics for Biotechnology to Biomicrofluidics

Berthier J., CEA-LETI, FR

In the biotechnology science, microfluidics is constantly adapting to the goals of biologists. Once a precise goal has been identified, biotechnology is searching for the best approaches to meet the demand of biologists. These approaches [...]

Investigation of the Concentration Polarization effect on Nanoparticles using radial micro-nanofluidic devices

Aïzel K., Fouillet Y., Pudda C., Chabrol C., Texier-Nogues I., CEA-LETI, FR

We perform ICP using radial silicon nanojunction geometries fabricated by single standard silicon microfabrication for proof of concept concentration operation over 50nm polystyrene nanobeads.We call the devices “Ring like devices” because of the circular shape [...]
