Solid-Electrolyte-Free O3-LixTiS2 Cathode for High-Energy-Density All-Solid-State Lithium-Metal Batteries

Benjamin Hennequart, Michael Deschamps, Ronan Chometon, Bernhard Leube, Romain Dugas, Elisa Quemin, Pierre-Etienne Cabelguen, Christophe Lethien, Jean-Marie Tarascon

Composites made of high-capacity and high-potential LiNixMnyCo1–x–yO2 (NMC) lamellar transition-metal oxides and S-based ionic conductors are primarily used as positive electrodes in all-solid-state batteries (ASSBs). However, NMC coatings are necessary to prevent the chemical reactivity of oxygen…

Modeling for nonlinear acoustic imaging of an isolated crack via standing waves in a 2D solid

Vladislav Aleshin, Ravi Verma, Kevin Truyaert

AbstractThis paper is concerned with numerical modeling for nondestructive imaging of defects in solids via standing waves excited by a periodic sinewave signal. The stationary solution, purely sinusoidal in an intact sample, contains higher harmonics when damage is present. These harmonics are…

Au@BN-enhanced laser desorption/ionization mass spectrometry and imaging for determination of fipronil and its metabolites in food and biological samples

Yanfang Zhao, Rabah Boukherroub, Guiju Xu, Huijuan Li, Ru-Song Zhao, Qin Wei, Xiang Yu, Xiangfeng Chen

Abstract Gold nanoparticles (AuNPs) represent an attractive inorganic matrix for laser desorption/ionization mass spectrometry (LDI-MS) detection of low-molecular-weight analytes; however, their direct use is hindered by severe aggregation. To limit AuNPs aggregation, hexagonal boron nitride…

Highly Si‐doped GaN regrown by MOVPE for ohmic contact applied to quaternary barrier based HEMT

Charles Pitaval, Cédric Lacam, N. Defrance, Christophe Gaquière, Nicolas Michel, Olivier Parillaud, Sylvain Delage

The quaternary barrier InAlGaN is suitable for GaN HEMT power microwave applications. High doping of semiconductor under the drain and source is a known suitable solution to achieve low ohmic contact resistance. However, InAlGaN quaternary alloys require low thermal budget to avoid indium…
