Kinematic and power analysis of a flapping-wing micro air vehicle using a Bond Graph approach

L Doan, E Cattan, S Grondel

Abstract Over the past few decades, the remarkable flight capabilities of insects have inspired extensive research into the development of flapping-wing micro air vehicles (FWMAVs). One of the primary challenges in this endeavor lies in navigating the vast spectrum of insect-inspired design options…

Spectral colour changes: a promising parameter for smart flax dew retting monitoring solutions

Suvajit Mukherjee, Dmitry Galinousky, Anne- Sophie Blervacq, Lionel Buchaillot, Steve Arscott, Sébastien Grec

Natural fibres from plants such as flax (Linum usitatissimum) are gaining interest as possible green replacements of synthetic fibres to reduce textile pollution footprints. However, the extraction-facilitating process of bast fibres from the flax stem, i.e. dew retting, is still empirically…

Competing effects of charge-carrier and impurity scattering limiting phonon heat conduction in heavily-doped silicon

Raja Sen, Juan Carlos Acosta Abanto, Mélanie Brouillard, Séverine Gomès, Jean-François Robillard, Alessandro Ciavatta, Lorenzo Paulatto, Nathalie Vast, Jérôme Saint-Martin, Jelena Sjakste, Pierre-Olivier Chapuis

With respect to undoped semiconductors, thermal transport by phonons is limited by two additional mechanisms when doping increases: charge-carrier and impurity scattering. Previous works provided contradicting conclusions on the dominant doping-induced scattering mechanism in silicon. In this work…

On the importance of Ni–Au–Ga interdiffusion in the formation of a Ni–Au/p-GaN ohmic contact

Jules Duraz, Hassen Souissi, Maksym Gromovyi, David Troadec, Téo Baptiste, Géraldine Hallais, Nathaniel Findling, Phuong Vuong, Rajat Gujrati, Thi May Tran, Jean-Paul Salvestrini, Maria Tchernycheva, Suresh Sundaram, Abdallah Ougazzaden, Gilles Patriarche, Sophie Bouchoule

High-resolution transmission electron microscopy (TEM) coupled to energy dispersive X-ray spectroscopy (EDX) is used to clarify the exact role of Ni-Au-Ga interdiffusion mechanisms taking place during rapid thermal annealing under an oxygen atmosphere of a Ni-Au/p-GaN contact. It is shown that…

Comment on “Influence of layer thickness on time domain Brillouin scattering oscillation amplitude in multilayer films” [J. Appl. Phys. 136, 225302 (2024)]

Simon Ayrinhac, Arnaud Devos, Benoît Rufflé, Marie Foret

Picosecond acoustics allows for the probing of multilayered nanometric structures, with applications in various fields of fundamental research. In a recent study, Zhang et al.1 have reexamined the optical cavity effect that impacts time-domain Brillouin acoustic spectroscopy (TDBS) in such systems…

DeeCLIP: A Robust and Generalizable Transformer-Based Framework for Detecting AI-Generated Images

Mamadou Keita, Wassim Hamidouche, Hessen Bougueffa Eutamene, Abdelmalik Taleb-Ahmed, Abdenour Hadid

This paper introduces DeeCLIP, a novel framework for detecting AI-generated images using CLIP-ViT and fusion learning. Despite significant advancements in generative models capable of creating highly photorealistic images, existing detection methods often struggle to generalize across different…

0.53 mΩ.cm 2 /592 V High Breakdown Voltage GaN-on-Sapphire Schottky Diodes Without Edge Termination

Hugo Bouillaud, Beatriz Orfao, Etienne Okada, Yannick Roelens, Malek Zegaoui, Mohammed Zaknoune

In this letter, we report high-performance Pt/GaN quasi-vertical Schottky barrier diodes on sapphire substrate. With a 5 μm drift layer and a highly controlled fabrication process, the devices demonstrate an extremely low on-resistance of 0.53 mΩ.cm² while exhibiting a high breakdown voltage of 592…

Plant- and Microalgae-Based Biotechnological Strategies for Affordable and Non-Invasive Delivery of Antidiabetic Peptides

Thibault Boscart, Alexandre Barras, Valérie Plaisance, Valérie Pawlowski, Emerson Giovanelli, Muriel Bardor, Christophe D’hulst, Amar Abderrahmani

The prevalence of diabetes and its worldwide co-morbidities is escalating. Therefore, the number of users of therapeutic peptides including insulin analogs and glucagon-like peptide 1 receptor agonists (GLP-1RAs), will unavoidably increase in the coming years. However, access to these two…
