AFM/SNOM Cantilever Probe Serial Fabrication Process with Controlled Tip Nanoaperture

Tsigara A., Belier B., Maillard F., Falgayrettes P., Nativel E., Kribich R., Gall-Borrut P., Universite Paris Sud, FR

In this paper we present the microfabrication steps of sol gel and polymer (SU8) based cantilever probe systems using an alternative batch front face fabrication process. The probes are consisting of cantilevers with pyramidal nanoengineered [...]

Counting and measuring micro and nano particles by using Fourier Interferometric Imaging

Saengkaew S., Garo A., Meunier-Guttin-Cluzel S., Grehan G., UMR CNRS 6614/CORIA, FR

The characterization of micro and nano particles suspensions is still a challenge, especially if very low concentration of particles mixtures are concerned. To reach this aim, optical techniques are attractive because they provide a fast [...]

Multiangle dynamic light scattering for the improvement of multimodal and polydisperse particle size distribution measurements

Boualem A., Ferre C., Jabloun M., Jalocha A., Naiim M., Ravier P., CILAS, FR

This work brings a new and improving method to the determination of multimodal and polydisperse particle size distribution by Dynamic Light Scattering. In this context, we develop a Bayesian method for the estimation of the [...]

Stabilization of mono- and bimetallic nanoparticles in ionic liquids

Darwich W., Arquillière P., Helgadottir I., Haumesser P.-H., Santini C.C., CEA/LETI/MINATEC, FR

Metallic nanoparticles (NPs) are needed in a range of applications such as the fabrication of advanced microelectronic, magnetic or optical devices. Hence, substantial effort has been centered on stabilizing transition-metal nanoparticles in wet synthesis processes, [...]

Interlayer interaction and disorder in Few Layer Graphene (FLG) powders prepared by fluidized bed chemical vapor deposition

Bacsa R., Bacsa W.S., Serp Ph., Lecante P., Pavlenko E., Cameán I., Ramos A., Garcia A.B., Bacsa R., Bacsa W.S., University of Toulouse, FR

The growth of few layer graphene (FLG) in powder form by CVD is particularly promising for its large scale production and use in composites as well as electrochemical and energy applications. The electronic and mechanical [...]

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 [...]

Wafer-scale integration of in-situ grown carbon nanotube membranes: a platform to study electrical properties

Le Poche H., Guerin H., Fournier A., Ramos R., Fayolle M., Delaunay M., Dijon J., Ionescu A.M., CEA-Liten, FR

Dense arrays of horizontal carbon nanotubes (CNTs) connected between two metallic electrodes and either supported on a silicon dioxide layer or suspended above a third gate electrode constitute a basic building block to achieve CNT-based [...]

Flexible fluorine-doped tin oxide based composite electrodes for photovoltaic applications

Giusti G., Puyoo E., Langley D.P., Consonni V., Bellet D., Laboratoire des Matériaux et du Génie Physique (LMGP), FR

Fluorine-doped tin dioxide (FTO) thin films were deposited via ultrasonic spray pyrolysis directly on preheated polyimide (PI) - DuPont™ Kapton® polyimide flexible film substrates. All the FTO films deposited on PI substrates exhibited polycrystalline cassiterite [...]

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 [...]

Nano-Organocatalysts: new magnetically retrievable tools for enantioselective synthesis

Nehlig E., Motte L., Guénin E., Université Paris, FR

We report the elaboration of new organocatalyst functionalized superparamagnetic iron oxide nanoparticles that can act as a new enantioselective organocatalyst. Differents organocatalysts are grafted using two different methodologies on a nanoplateform constituted of 10 nm [...]
