Characterization and modeling of 650V GaN diodes for high frequency power conversion

Doublet Martin, N. Defrance, Loris Pace, Etienne Okada, Thierry Dusquesne, Emmanuel Collard, Yvon Arnaud, Nadir Idir, Jean-Claude de Jaeger

The constant growth of electric consumption leads to considerable progress in power conversion. Recent studies have shown that using Gallium Nitride (GaN) as a technological building bloc permits to develop converter operating at high frequency with reduced volume and weight. Furthermore, it is...

Development of a millimeter-long Travelling wave THz photomixer

Fuanki Bavedila, Charbel Tannoury, Quyang Lin, Sylvie Lepilliet, Vanessa Avramovic, Etienne Okada, Dmitri Yarekha, Marc Faucher, David Troadec, Jean-Francois Lampin, Guillaume Ducournau, Goulc'Hen Loas, Vincent Magnin, Emilien Peytavit

THz sources based on the optical-heterodyne (photo)mixing in an ultrafast photodetector are very promising since they operate at room temperature, are potentially compact, cost-efficient and, above all, are widely frequencytunable. However, their widespread use is currently hampered by available...

Molecular beam epitaxial growth of hexagonal boron nitride on Ni foils

Jawad Hadid, Ivy Colambo, Christophe Boyaval, Nicolas Nuns, Pavel Dudin, Jose Avila, X. Wallart, Dominique Vignaud

Hexagonal boron nitride was synthesized by molecular beam epitaxy on polycrystalline Ni foils using borazine (B 3 N 3 H 6) as precursor. Our photoemission analysis shows that several components of boron and nitrogen are detected, suggesting the complex nature of the bonds noticeably at the h-BN/Ni...

Naturally Abundant Green Moss for Highly Efficient Solar Thermal Generation of Clean Water

Masuod Khajevand, Saeid Azizian, Rabah Boukherroub

Water and energy scarcity are the challenges for humankind in the coming years. Sun is the largest source of energy available on the planet. Also, brackish seawater covers more than 70% of the surface of the planet. Therefore, combining these two valuable natural resources represents an appealing...

A critical review on surface modifications mitigating dairy fouling

Manon Saget, Caroline Françolle Almeida, Vanessa Fierro, Alain Celzard, Guillaume Delaplace, V. Thomy, Yannick Coffinier, Maude Jimenez

Thermal treatments performed in food processing industries generate fouling. This fouling deposit impairs heat transfermechanism by creating a thermal resistance, thus leading to regular shutdown of the processes. Therefore, periodic and harsh cleaning-in-place (CIP) procedures are implemented....

Modeling for nonlinear laser vibrometry ex-periments in solids with frictional cracks

Ravi Verma, Kevin Truyaert, Vladislav Aleshin

Modeling for processes underlying NDT and SHM by ultrasound and vibrations present certain benefits. A valid digital tool can help accept or reject a hypothesis on damage position, orientation and degree of gravity. As a final objective, a fully reconstructed damage configuration can supplement...

Railway Obstacle Detection Using Unsupervised Learning: An Exploratory Study

Amine Boussik, Wael Ben Messaoud, Smail Niar, Abdelmalik Taleb-Ahmed

Autonomous Driving (AD) systems are heavily reliant on supervised models. In these approaches, a model is trained to detect only a predefined number of obstacles. However, for applications like railway obstacle detection, the training dataset is limited and not all possible obstacle classes are...

Can an Inorganic Coating Serve as Stable SEI for Aqueous Superconcentrated Electrolytes?

Léa Droguet, Gustavo Hobold, Marie Francine Lagadec, Rui Guo, Christophe Lethien, Maxime Hallot, Olivier Fontaine, Jean-Marie Tarascon, Betar Gallant, Alexis Grimaud

Developing a stable, conformal solid electrolyte interphase (SEI) for aqueous-based Li-ion batteries has been a long-awaited dream to support the development of nontoxic and eco-friendly energy storage technologies. Toward that goal, aqueous superconcentrated electrolytes were recently introduced...

[Retracted] Rapid generation of coronaviral immunity using recombinant peptide modified nanodiamonds

Rostyslav Bilyy, Quentin Pagneux, Nathan François, Galyna Bila, Roman Grytsko, Yuri Lebedin, Alexandre Barras, Jean Dubuisson, Sandrine Belouzard, Karin Séron, Rabah Boukherroub, Sabine Szunerits

Vaccination remains one of the most effective tools to prevent infectious diseases. To ensure that the best possible antigenic components are chosen to stimulate a cognitive immune response, boosting antigen presentation using adjuvants is common practice. Nanodiamond-based adjuvants are proposed...
