Correlating electrical and structural properties in surface layer of carbon nanotube polymer composite

Pavlenko E., Tishkova V., Puech P., Bacsa W.S., CNRS and University of Toulouse, FR

We have recently shown that annealing of agglomerated carbon nanotubes on thermoplast polymers form surface composite films (70 micrometers) (1). This has been explained by preferential carbon nanotubes absorption of infrared radiation leading to local [...]

Monitoring nanoparticle growth in a microreactor by combined micro-SAXS and micro-Raman techniques

Reynolds M., Di Cola E., Sztucki M., Gourrier A., Montero C., Burghammer M., European Synchrotron Radiation Facility, FR

Noble metal nanoparticles have been extensively exploited in recent decades for their importance in fundamental science and their applications in biomedical therapeutics, catalysis and as a bottom-up approach to the production of ordered nanostructures. Key [...]

Rechargeable Lithium-ion Batteries For Wireless Smart Designs

Fusalba F., CEA-Liten, 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 [...]

FEM study of a 3-axis thermal accelerometer based on free convection in a microcavity

Nguyen H.B., Mailly F., Latorre L., Nouet P., University Montpellier 2 / CNRS - LIRMM, FR

Thermal convective accelerometers are based on heat transfer in a sealed cavity filled with a fluid. The principle was patented in the 40’s and the first implementations on silicon, obtained with bulk micromachining, were reported [...]

Electromechanical response of high frequency silicon nanowire resonators:simulation and measurements

Koumela A., Mercier D., Marcoux C., Purcell S.T., Hentz S., Duraffourg L., CEA-LETI, FR

Electromechanical models of nano-electromechanical devices are usually implemented with specifically developed mathematical software and these models are not easily compatible with circuit simulation software. However, in order to use a nano-device as a sensor, a [...]

Functionalization of self-organized networked SiOxHyCz nano-islands deposited by atmospheric pressure microwave plasma torch on Au/Si(100) substrates patterned by nano-indentation

Landreau X., Boëns B., Lanfant B., Merle T., Bouscarrat G., Dublanche-Tixier C., Zerrouki R., Tristant P., Université de Limoges, FR

A coaxial injection microwave excited plasma torch operating at atmospheric pressure is applied to synthesizing SiOxHyCz nano-islands from hexamethyldisiloxane precursor on prepatterned Au/Si(100) substrates.Prior to the PECVD deposition, the substrates are patterned by nano-indentation. SEM [...]

Nanovias FIB-etching and filling in a micro-nano interposer for molecular electronics

Gac G.L., Audoit G., Thuaire A., Rauer C., Moriceau H., Baillin X., CEA-Grenoble, FR

As molecular electronics is getting more and more explored, a device enabling electrical characterization of the synthesized molecules becomes necessary. A micro-nano interposer is thus developed to allow connection between a molecular circuit and mesoscopic [...]

New microfluidic chip for the production of spherical gelled capsule for cell encapsulation

Dalle P., Morales S., Berthier J., Benhamou P-Y., Bellemin Comte A., Boizot F., Costa G., Rivera F., CEA-LETI, FR

Implantation of Langerhans islet in alginate shell is an alternative for the treatment of diabetes type 1. Finding an adapted process for cell encapsulation is a challenge. The process must product spherical and monodisperse capsules [...]

Multi-functional silica microdot arrays by inkjet printing for biosensor applications

De Los Cobos O., Lejeune M., Rossignol F., Carrion C., Boissière C., Ribot F., Sanchez C., Cattoën X., Wong Chi Man M., Durand J.-O., SPCTS, FR

Silica-based microarrays for molecular recognition are realized using a piezoelectric drop-on-demand inkjet printer. A sol containing tetraethyl orthosilicate (TEOS) and (3-azidopropyl)triethoxysilane is used as ink to print azido-functionalized mesoporous silica microdots arrays clickable with various [...]
