Influence of viscosity on acoustic streaming in sessile droplets: an experimental and a numerical study with a Streaming Source Spatial Filtering (SSSF) method

Antoine Riaud, Michael Baudoin, Olivier Bou Matar, Jean-Louis Thomas, Philippe Brunet

When an acoustic wave travels in a lossy medium such as a liquid, it progressively transfers its pseudo-momentum to the fluid, which results in a steady flow called acoustic streaming. This phenomenon involves a balance between sound attenuation and shear, such that the streaming flow does not…

A New Photomechanical Molecular Switch Based on a Linear π-Conjugated System

Stéphane Lenfant, Yannick Viero, Christophe Krzeminski, Dominique Vuillaume, Dora Demeter, I. L. Dobra, Maiténa Oçafrain, Philippe Blanchard, Jean Roncali, C. van Dick, Jérôme Cornil

We report the electron-transport properties of a new photoaddressable molecular switch. The switching process relies on a new concept based on linear π-conjugated dynamic systems, in which the geometry and, hence, the electronic properties of an oligothiophene chain can be reversibly modified by…

High Frequency Acoustic On-Chip Integration for Particle Characterization and Manipulation in Microfluidics

Sizhe Li, Julien Carlier, Malika Toubal, Huiqin Liu, Pierre Campistron, Dorothee Callens, Georges Nassar, Bertrand Nongaillard, Shishang Guo

This letter presents a microfluidic device that integrates high frequency (650 MHz) bulk acoustic waves for the realization of particle handling on-chip. The core structure of the microfluidic chip is made up of a confocal lens, a vertical reflection wall, and a ZnO film transducer coupled with a…

Atomic-scale structure of the glassy Ge 2 Sb 2 Te 5 phase change material: A quantitative assessment via first-principles molecular dynamics

Assil Bouzid, Guido Ori, Mauro Boero, Evelyne Lampin, Carlo Massobrio

The amorphous structure of the phase change material Ge2Sb2Te5 (GST) has been the object of controversial structural models. By employing first-principles molecular dynamics within density functional theory, we are able to obtain quantitative agreement with experimental structural findings for the…

Impact of Gate Drain Spacing on Low-Frequency Noise Performance of In Situ SiN Passivated InAlGaN/GaN MIS-HEMTs

Mehdi Rzin, Jean-Marc Routoure, Bruno Guillet, Laurence Méchin, Magali Morales, Cédric Lacam, Piero Gamarra, Pierre Ruterana, F Medjdoub

In this paper we investigated the gate–drain access region spacing (L GD) effect on electrical and noise performance of InAlGaN/GaN metal– insulator–semiconductor high electron mobility transistors (MIS-HEMTs) using in situ SiN cap layer as gate insulator. Different L GD of InAlGaN/GaN MIS-HEMTs…

Low Source/Drain Contact Resistance for AlGaN/GaN HEMTs with High Al Concentration and Si-HP [111] Substrate

Steven Duffy, Brahim Benbakhti, Maghnia Mattalah, Wei Zhang, Meriem Bouchilaoun, Mohammed Boucherta, Karol Kalna, Nour Eddine Bourzgui, Maher, Hassan, Ali Soltani

An optimized fabrication process of ohmic contacts is proposed to reduce the source/drain access resistance (RC) and enhance DC/RF performance of AlGaN/GaN HEMTs with a high Al concentration. We show that source/drain RC can be considerably lowered by (i) optimally etching into the barrier layer…

Low Complexity Joint Blind Equalization and CFO Estimation for MC-CDMA System

Kais Bouallegue, Iyad Dayoub, M Gharbi, Kaïs Hassan, R. Masmoudi, A. Djebbar

Based on the orthogonality between the used and the unused spreading codes (excess codes) subspaces in one hand and on the restoration of guard interval redundancy of Multicarrier Code Division Multiple Access signal in other hand, we propose joint Carrier Frequency Offset and time domain equalizer…

Correction to: Effect of incubation duration, growth temperature, and abiotic surface type on cell surface properties, adhesion and pathogenicity of biofilm-detached Staphylococcus aureus cells

Oussama Khelissa, Charafeddine Jama, Marwan Abdallah, Rabah Boukherroub, Christine Faille, Nour-Eddine Chihib

Following publication of the original article (Khelissa et al. 2017), the authors reported that the legend for Fig. 3 contained an error. Instead of “Adhesion of planktonic and biofilm-detached Staphylococcus aureus cells on stainless steel and polycarbonate. Cell cultures were grown at 20, 30 and…
