Direct observation of edge modes in zigzag granular chains

Li-Yang Zheng, Shilin Qu, Florian Allein, Théo Thréard, Vitali Goussev, Vincent Tournat, Georgios Theocharis

As a new class of artificial elastic materials, granular crystals are mechanical structures of elastic beads arranged in contact through a lattice. One important feature of wave dynamics in granular crystals is that it highly relies on the contact mechanics, allowing for exotic wave transport...

[Invited] 2D-BN growth on nickel under ultra-high vacuum conditions from borazine

J. Hadid, D. Vignaud, X. Wallart

Graphene is a 2D material, famous for its exceptional electronic properties. However, to exploit these properties in real devices, the electronic coupling with the substrate and with any surrounding material must be strongly reduced. Hexagonal boron nitride (hBN), another 2D material, is very...

Face Presentation Attack Detection Using Deep Background Subtraction

Azeddine Benlamoudi, Salah Eddine Bekhouche, Maarouf Korichi, Khaled Bensid, Abdeldjalil Ouahabi, Abdenour Hadid, Abdelmalik Taleb-Ahmed

Currently, face recognition technology is the most widely used method for verifying an individual’s identity. Nevertheless, it has increased in popularity, raising concerns about face presentation attacks, in which a photo or video of an authorized person’s face is used to obtain access to services...

Synthesis and characterization of a novel multi-functionalized reduced graphene oxide as a pH-sensitive drug delivery material and a photothermal candidate

Maryam Mirza-Aghayan, Maryam Heidarian, Marzieh Mohammadi, Rabah Boukherroub

In this work, we describe a simple and effective method for the synthesis of a novel multi-functionalized reduced graphene oxide (rGO/DA/Au NPs/DOX) through the successive reaction of graphene oxide (GO) with dopamine (DA), HAuCl4/NaBH4 and doxorubicin (DOX) under mild conditions. The rGO/DA/Au NPs...

A Biosensor Based on Bound States in the Continuum and Fano Resonances in a Solid–Liquid–Solid Triple Layer

Ilyasse Quotane, Madiha Amrani, Cécile Ghouila-Houri, El Houssaine El Boudouti, Leonid Krutyansky, Bogdan Piwakowski, Philippe Pernod, Abdelkrim Talbi, Bahram Djafari-Rouhani

We propose a simple solid–liquid–solid triple layer biosensor platform based on bound states in the continuum (BICs) and Fano resonances to detect the acoustic properties of liquids and apply the method to a mixture of water and albumin with various concentrations. The solid–liquid–solid triple...

An acoustician’s approach of the solid body electric guitar, Approche de la guitare électrique solid body par l’acoustique

Arthur Paté, Jean-Loïc Le Carrou, Benoît Fabre

The perceived sound of a solid body electric guitar mainly results from the electroacoustic system that radiates the signal of vibrating strings. Most of the previous works in acoustics and audio signal processing focused on amplifiers, effect pedals, pickups, etc. However, sound originates from..., Le son perçu d’une guitare électrique solid body provient principalement du système électroacoustique rayonnant le signal de vibration des cordes. L’essentiel des travaux antérieurs en acoustique et traitement du signal audio s’est ainsi focalisé sur les amplificateurs, pédales d’effet, pickups,...

Abstract We study experimentally and theoretically the dynamics of spin relaxation motion excited by a femtosecond pulse in the TbCo 2 /FeCo multilayer structures with different ratios of TbCo 2 to FeCo thicknesses r d = d T b C o 2 / d F e C o . The main attribute of the structure is in-plane...
