Finite element analysis and experimental study of surface acoustic wave propagation through two-dimensional pillar-based surface phononic crystal

S. Yankin, Abdelkrim Talbi, Y. Du, Jean-Claude Gerbedoen, Vladimir Preobrazhensky, Philippe Pernod, Olivier Bou Matar

We study both theoretically and experimentally the interaction of surface elastic waves with 2D surface phononic crystal (PnC) on a piezoelectric substrate. A rigorous analysis based on 3D finite element method is conducted to calculate the band structure of the PnC and to analyze the transmission...

Surface asymmetry of coated spherical nanoparticles

Amélie H.R. Koch, Gaëtan Lévêque, Sebastian Harms, Karmena Jaskiewicz, Max Bernhardt, Andreas Henkel, Carsten Sönnichsen, Katharina Landfester, George Fytas

We validate the nonspherical grafting arrangement of isotropically coated spherical nanoparticles as very recently proposed. We utilize localized surface plasmon resonance enhanced dynamic polarized and depolarized light scattering from Au nanoparticles, the spherical symmetry of which was revealed...

CIGSe absorber layers deposition by single target magnetron sputtering

R. Meunier, S. Fabert, M. Ricci, P.Y. Thoulon, Thomas Aviles, Jean-Pierre Vilcot, Alain Lafond, Michèle Carette, Pierre-Yves Jouan, Marie-Paule Besland

In the last decades, the deposition of CIGSe thin films by sputtering has seldom been investigated. Besides, the sputtering of a single quaternary CIGSe target would be a real advantage for industrial development. Indeed, sputtering technique exhibits a good compatibility with industrial up-scaling...

In situ integrated tuner approach for load-pull measurement of Si/SiGe:C HBT at 200 GHz

Issam Hasnaoui, Alexandre Pottrain, Thomas Lacave, Pascal Chevalier, Daniel Gloria, Christophe Gaquière

Load impedance variations were obtained using an innovative integrated tuner at G-band. The 200 GHz load-pull measurements on a silicon-germanium (SiGe) heterojunction bipolar transistor (HBT) are presented. First, the linearity of the integrated tuner is checked. Then, the main load-pull...

Diffusion based kinetic selectivity modulation of enzymatic proteolysis in a microfluidic reactor : experimental analysis and stochastic modeling

Adil Elagli, Simon Laurette, A. Treizebre, Bertrand Bocquet, Renato Froidevaux

Microreactors enable new experimental ways for enzyme engineering. In this context, we show that the liquid-liquid parallel laminar flows in microchannels cause a kinetic selectivity modification of proteolytic enzymatic reaction involving hemoglobin and pepsin, reaction that generates numerous...
