Developing a MEMS device with built-in microfluidics for biophysical single cell characterization

Yuki Takayama, Grégoire Perret, Momoko Kumemura, Manabu Ataka, Samuel Meignan, Stanislav Karsten, Hiroyuki Fujita, Dominique Collard, Chann Lagadec, Mehmet Tarhan

This study combines the high-throughput capabilities of microfluidics with the sensitive measurements of microelectromechanical systems (MEMS) technology to perform biophysical characterization of circulating cells for diagnostic purposes. The proposed device includes a built-in microchannel that...

Wavefront steering of elastic shear vertical waves in solids via a composite-plate-based metasurface

Jun Zhang, Xiaoshi Su, Yan Pennec, Yun Jing, Xiaofeng Liu, Ning Hu

We report a novel approach to control the wavefronts of shear vertical (SV) waves in solids using metasurfaces constituted by a stacked array of composite plates, which are composed of two connecting parts made of different materials. The metasurfaces are connected at two ends to the halfspace...

Adaptive Channel estimation technique for ITS-G5 inter- vehicular communication systems

Aymen Sassi, Yassin El Hillali, Atika Rivenq

In recent years, vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communication systems, known as V2X technologies, have been the interest of several research works in road safety and traffic ergonomics. The evaluation of their performance is a substantial step before their probable...

A Novel Integrated Way for Deciphering the Glycan Code for the FimH Lectin

Eva-Maria Krammer, Julie Bouckaert, Rostyslav Bilyy, Ralf Blossey, Sabine Szunerits, Solomiya Paryzhak, Marc Lensink, Sebastien Gouin, Clarisse Bridot, Tetiana Dumych

The fimbrial lectin FimH from uro- and enteropathogenic Escherichia coli binds with nanomolar affinity to oligomannose glycans exposing Manα1,3Man dimannosides at their non-reducing end, but only with micromolar affinities to Manα1,2Man dimannosides. These two dimannoses play a significantly...

Impact of unintentional oxygen doping on organic photodetectors

Julie Euvrard, Amelie Revaux, Alexandra Cantarano, Stephanie Jacob, Antoine Kahn, Dominique Vuillaume

Oxygen plasma is a widely used treatment to change the surface properties of organic layers. This treatment is particularly interesting to enable the deposition from solution of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) on top of the active layer of organic solar cells or...

Multimodal microscopy test standard for scanning microwave, electron, force and optical microscopy

Olaf C. Haenssler, M. F. Wieghaus, A. Kostopoulos, G. Doundoulakis, E. Aperathitis, S. Fatikow, G. Kiriakidis

We report on measurement results of a test standard suitable for different microscopic modalities. These findings were obtained by a multimodal hybrid microscope, which requires various calibration methods, also in terms of its further use as a tool in a nanorobotic environment. A Scanning Probe...

Extrinsic capacitance extraction for GaAs and GaN FETs from low to high temperatures

Mohammad A. Alim, Ali A. Rezazadeh, Christophe Gaquière, Giovanni Crupi

The main aim of this article is to present an experimental analysis of the thermal influence on the positive derivatives of the real parts of impedance parameters against frequency (PDRZ) for microwave GaN and GaAs based HEMTs. The PDRZ effect is investigated with respect to temperature by both...

Graphene FETs Based on High Resolution Nanoribbons for HF Low Power Applications

David Mele, Sarah Mehdhbi, Dalal Fadil, Wei Wei, Abdelkarim Ouerghi, Sylvie Lepilliet, Henri Happy, Emiliano Pallecchi

In this paper we present high frequency field effect transistors based on graphene nanoribbons arrays (GNRFETs). The nanoribbons serve as a channel for the transistors and are fabricated with a process based on e-beam lithography and dry etching of high mobility hydrogen intercalated epitaxial...

GaN-Based Laser Wireless Power Transfer System

Carlo de Santi, Matteo Meneghini, Alessandro Caria, Ezgi Dogmus, Malek Zegaoui, F Medjdoub, Boris Kalinic, Tiziana Cesca, Gaudenzio Meneghesso, Enrico Zanoni

The aim of this work is to present a potential application of gallium nitride-based optoelectronic devices. By using a laser diode and a photodetector, we designed and demonstrated a free-space compact and lightweight wireless power transfer system, whose efficiency is limited by the efficiency of...
