3D Patterning of Si by Contact Etching With Nanoporous Metals

Stéphane Bastide, Encarnacion Torralba, Mathieu Halbwax, Sylvain Le Gall, Elias Mpogui, Christine Cachet-Vivier, Vincent Magnin, Joseph Harari, Dmitri Yarekha, Jean-Pierre Vilcot

Nanoporous gold and platinum electrodes are used to pattern n-type silicon by contact etching at the macroscopic scale. This type of electrode has the advantage of forming nanocontacts between silicon, the metal and the electrolyte as in classical metal assisted chemical etching while ensuring…

Performance assessment of a small-size ocean wave energy harvester

Yongjie Sang, Bertrand Dubus

A lightweight electromechanical device is studied to harvest energy of ocean waves and supply electrical power to small-size ocean observation equipment such as sonobuoys. It is composed of a magnet fixed to the floating housing which follows the motion of the ocean surface and a moving coil…

On the impact of the covariance matrix size for spectrum sensing methods:beamforming versus eigenvalues

Kais Bouallegue, Matthieu Crussière, Iyad Dayoub

In this paper, we investigate the impact of the covariance matrix (CM) size of the received signal on the performance of spectrum sensing methods. Our analysis is based on two well-known methods of spectrum sensing (SS), one based on the eigenvalues called maximum-to minimum eigenvalue (MME) and…

A method to determine wide bandgap power devices packaging interconnections

Loris Pace, N. Defrance, Jean-Claude de Jaeger, Arnaud Videt, Nadir Idir

Wide Bandgap (WBG) power devices show very good characteristics for high frequency operation in power converters, leading to a better power integration by reducing size and weight of passive components. Access parasitics such as resistances and inductances related to packaging and interconnections…

Exploring Light-Sensitive Nanocarriers for Simultaneous Triggered Antibiotic Release and Disruption of Biofilms Upon Generation of Laser-Induced Vapor Nanobubbles

Eline Teirlinck, Alexandre Barras, Jing Liu, Juan Andrés A Fraire, Tatu Lajunen, Ranhua Xiong, Katrien Forier, Chengnan Li, Arto Urtti, Rabah Boukherroub, Sabine Szunerits, Stefaan C de Smedt, Tom Coenye, Kevin Braeckmans

Impaired penetration of antibiotics through bacterial biofilms is one of the reasons for failure of antimicrobial therapy. Hindered drug diffusion is caused on the one hand by interactions with the sticky biofilm matrix and on the other hand by the fact that bacterial cells are organized in densely…

Blocking bacterial entry at the adhesion step reveals dynamic recruitment of membrane and cytosolic probes

Yann Ciczora, Sébastien Janel, Magali Soyer, Michka Popoff, Elisabeth Werkmeister, Frank Lafont

Background: Bacterial invasion covers two steps: adhesion and entry per se. The cell signalling response is triggered upon pathogen interaction at the cell surface. This response continues when the pathogen is internalised. It is likely that these two steps activate different molecular machineries…

Ferroelectric multiple-valued logic units

Igor A. Luk'Yanchuk, Elena Zaitseva, Vitaly Levashenko, Miroslav Kvassay, Svitlana Kondovych, Yuri Tikhonov, Laurent Baudry, Anna Razumnaya

Employing many-valued logic (MVL) data processing allows to dramatically increase the performance of computing circuits. Here we propose to employ ferroelectrics for the material implementation of MVL units basing on their ability to pin the polarization as a sequence of multi-stable states. Two…

Design of a four-branch optical power splitter based on gallium-nitride using rectangular waveguide coupling for telecommunication links

Retno Wigajatri Purnamaningsih, Nji Raden Poespawati, El Hadj Dogheche

This paper reports design of a simple four-branch optical power splitter using five parallel rectangular waveguides coupling in a gallium-nitride (GaN) semiconductor/sapphire for telecommunication links. The optimisation was conducted using the 3D FD-BPM method for long wavelength optical…

On a generic theory of the organic electrochemical transistor dynamics

Vasileios Athanasiou, Sébastien Pecqueur, Dominique Vuillaume, Zoran Konkoli

In the recent years, the organic electrochemical transistors (OECT) have attracted considerable attention for biosensing applications due to the biocompatibility of their materials and their low operating voltages. Upon exposure to an electrolyte, the drain current becomes ion-dependent. This can…

Evaluation of the hydrophobic properties of latex microspheres and <em>Bacillus</em> spores. Influence of the particle size on the data obtained by the MATH method (microbial adhesion to hydrocarbons)

Christine Faille, Christelle Lemy, Audrey Allion-Maurer, Farzam Zoueshtiagh

The current experimental study investigates the influence of latex microsphere particles' size on the assessment of their hydrophilic/hydrophobic character, using the method known as “Microbial Adhesion to Hydrocarbons” (MATH). Since bacteria surfaces often change according to the environment…
