A Grand Canonical Monte-Carlo Simulation of the Textural, Mechanical and Adsorption Properties of Faujasite zeolite Carbon Replica

Roussel T., Bichara C., Pellenq R.J.-M., Centre de Recherche en Matière Condensée et Nanosciences, CNRS, FR

The development of the negative templating process to obtain a carbon replica from an ordered inorganic template has lead to the synthesis of new carbon materials which have interesting textural properties attractive for energy storage. [...]

Composite Carbon Nanostructures as Promising Carriers for Gaz Analysis

Majoli L., Evstratov A., Guillot J.-M., Rouvière A., Baussand P., Ales High Mining School, FR

In the framework of the project ACI NPD-37 “NSC-Env” supported by the French Ministry of Research and New Technologies, a kind of nanostructured carbon based composite materials was developed in order to propose new efficient [...]

Diagnostics of carbon nanotube composites by Raman spectroscopy

Puech P., Bassil A., Barrau S., Demont P., Bacsa R.R., Bacsa W.S., Flahaut E., Bacsa R.R., Bacsa W.S., University Paul Sabatier, FR

Carbon nanotube polymer composites are very promising for applications due to their exceptional mechanical and electronic properties to improve the elastic properties of polymers or to make polymers conductive. The large surface of carbon nanotubes [...]

Nanostructured Metals Synthesized in Swollen Liquid Crystals

Surendran G., Ramos L., Prouzet E., Remita H., CNRS, FR

We have developed a flexible approach for the preparation of nanostructured materials using swollen liquid cristals (SLCs) that exhibit hexagonal, cubic or lamellar symmetry as soft templates.Hexagonal SLCs consist in a regular packing of infinite [...]

Revealing of a Particular Physical Mechanism of Disordered Photocatalytic Structure Functioning

Evstratov A., Chis C., Taulemesse J.-M., Gaudon P., Peirano F., Ales Hihg Mining School, FR

Both reduction and oxidation products are simultaneously formed at the surface of the crystalline (“classic”) photocatalysts. As to probable photocatalytic properties of disordered structures, their functioning could be provided by a reinforced artificial separation of [...]

Compact Modeling of Threshold Voltage in Double-Gate MOSFET including Quantum Mechanical and Short Channel Effects

Nehari K., Munteanu D., Autran J-L, Harrison S., Tintori O., Skotnicki T., L2MP-CNRS, FR

Compact modeling of Double-Gate MOSFET incites very much interest presently, since DG is considered to be the best candidate for the integration at the end-of-roadmap. The aim of this work is to develop a short-channel [...]

A Compact Model for the Threshold Voltage of Silicon Nanowire MOS Transistors including 2D-Quantum Confinement Effects

Nehari K., Autran J-L, Munteanu D., Bescond M., L2MP-CNRS, FR

A quantum-mechanical compact model of the threshold voltage for quantum-wire (QW) MOSFETs has been developed. This approach is based on analytical 2D solutions for the decoupled Schrödinger and Poisson equations solved in a 2D cross-section [...]

An Atomistic Simulation Study of Carbon Nanostructure Growth in the Porosity of Different Zeolites

Roussel T., Bichara C., Pellenq R.J.-M., Centre de Recherche en Matière Condensée et Nanosciences, CNRS, FR

In this work, we present Grand Canonical Monte-Carlo simulation results for the adsorption of carbon vapour in the pores of various zeolites: AlPO4-5, silicalite and Faujasite (both in its sodium and siliceous form). The carbon-carbon [...]

IDEA, a CAD Tool for the Design of Deformable Micro-Structures: Extension to the 2D Deformation of Arbitrarily-Shaped Membranes

Juillard J., Colinet E., SUPELEC, FR

A method for solving design problems involving coupled-field physics is presented: it is demonstrated in the case of the electrostatic actuation of a deformable micro-mirror. The focus of the present paper is on the inversion [...]

Design, Modelling and Optimisation of Integrated Piezoelectric Micro Power Generators

Marzencki M., Basrour S., Charlot B., TIMA, FR

This paper presents a mechanical vibration energy scavenging solution for micro power generation. The transduction is performed using a novel resonant cantilever beam SOI structure with a piezoelectric film. Simulation and optimization of such a [...]
