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…

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…

Finite element modeling of a piezoelectric slender bar transducer equipped with a multilayer backing for medical imaging applications

Nadia El Atlas, Abdelmajid Bybi, Hilal Drissi, Anne-Christine Hladky

The goal of this work is to investigate the impact of front and back matching layers properties on a piezoelectric slender bar transducer performances and to propose a novel multilayer backing absorber. Quarter-wavelength acoustic matching layers and backing are known as essential components to…

On demand electrochemical release of drugs from porous reduced graphene oxide modified flexible electrodes

Samia Boulahneche, Roxana Jijie, Alexandre Barras, Fereshteh Chekin, Santosh K Singh, Julie Bouckaert, Mohamed Salah Medjram, Sreekumar Kurungot, Rabah Boukherroub, Sabine Szunerits

Despite the advantages of an electrochemical control for drug release, only a handful of electrochemical-based release systems have been developed so far. We report herein on the development of an electrochemically activatable platform for on-demand delivery of drugs. It is based on flexible gold…

Selective Manipulation of Microscopic Particles with Precursor Swirling Rayleigh Waves

Antoine Riaud, Michael Baudoin, Olivier Bou Matar, Loic Becerra, Jean-Louis Thomas

Contactless manipulation of microparticles is demonstrated with single-beam acoustical tweezers based on precursor swirling Rayleigh waves. These surface waves degenerate into acoustical vortices when crossing a stack made of a fluid layer and its solid support, hence creating a localized…

Modeling and optimization of core/shell p-i-n Si/Si0.2Ge0.8 nanowire for photovoltaic

Fethi Benyettou, Abdelkader Aissat, Isabelle Berbezier, Jean-Pierre Vilcot

In this work we propose a modeling and simulation of core/shell p-i-n Si/Si0.2Ge0.8 nanowire for photovoltaic. In the first step of this work, we have compared the core/shell p-i-n homo-junction Si and heterojunction Si/Si0.2Ge0.8 Nanowire (NW) solar cell having a length of 3 mu m and a radius of 0…

Three-dimensional (3D) culture of adult murine colon as an in vitro model of cryptosporidiosis: Proof of concept

Martha Baydoun, Sadia Benamrouz Vanneste, Colette Creusy, Karine Guyot, Nausicaa Gantois, Magali Chabe, Baptiste Delaire, Anthony Mouray, Atallah Baydoun, Gerard Forzy, Vincent Chieux, Pierre Gosset, Vincent Senez, Eric Viscogliosi, Jérôme Follet, Gabriela Certad

Cryptosporidium parvum is a major cause of diarrheal illness and was recently potentially associated with digestive carcinogenesis. Despite its impact on human health, Cryptosporidium pathogenesis remains poorly known, mainly due to the lack of a long-term culture method for this parasite. Thus,…

TUNING NEGATIVE DIFFERENTIAL RESISTANCE IN A SINGLE MOLECULE TRANSISTOR: DESIGNS OF LOGIC GATES AND EFFECTS OF VARIOUS OXYGEN-AND HYDROGEN-INDUCED DEFECTS

A Nasri, A Boubaker, B Hafsi, W Khaldi, A Kalboussi

In this paper, a theoretical study of Single Molecule Transistor (SMT) operating as a molecular field effect transistor (MFET) has been presented. We have applied the density functional theory (DFT) in conjugation with the non-equilibrium green's function (NEGF) formalism on a pentacene device…
