Immunity to Backscattering of Bulk Waves in Topological Acoustic Superlattices

P A Deymier, Jérome O Vasseur, K. Runge, A. Khanikaev, A. Alù

We herein investigate the scattering of orthogonal counterpropagating waves and one-way propagating bulk waves in discrete acoustic superlattices subjected to a scattering potential applied to one of the superlattice unit cells. We demonstrate theoretically that the orthogonality of...

A Tight-Binding Model for Illustrating Exciton Confinement in Semiconductor Nanocrystals

Z. Hens, Christophe Delerue

The Brus equation describes the relation between the lowest energy of an electron–hole pair and the size of a semiconductor crystallite. However, taking the strong confinement regime as a starting point, the equation does not cover the transition from weak to strong confinement, the accompanying...

Enabling Low-Power Signature Recognition for the IoT with SLIF neurons

Guillaume Marthe, Claire Goursaud, Laurent Clavier

Energy constraints are still a significant challenge in numerous IoT applications, particularly due to the excessive power consumption of microcontrollers. To overcome this limitation, novel circuit designs have been introduced, with the integration of spiking neurons and analog computing emerging...

FT-IR detection of DMMP on TiO 2 -Modified Porous Silicon Substrates

Warda Raiah, M. Guendouz, Parastesh Pirasteh, Vincent Thomy, Joël Charrier, Yannick Coffinier

In this study, we present a new chemical sensor based on a functionalized porous silicon and sensitive to dimethyl methyl phosphonate (DMMP), a simulant of sarin gas, known as one of the most toxic warfare agents. The porous silicon was prepared by anodising a boron-doped p-Si (100) wafer. A metal...

Transcriptomic profiling analysis of the effect of palmitic acid on 3D spheroids of β-like cells derived from induced pluripotent stem cells

Lisa Morisseau, Fumiya Tokito, Mathilde Lucas, Stéphane Poulain, Soo Hyeon Kim, Valérie Plaisance, Valérie Pawlowski, C. Legallais, Rachid Jellali, Yasuyuki Sakai, Amar Abderrahmani, Eric Leclerc

Type 2 diabetes (T2D) is posing a serious public health concern with a considerable impact on human life and health expenditures worldwide. The disease develops when insulin plasma level is insufficient for coping insulin resistance, caused by the decline of pancreatic β-cell function and mass. In...

[Review] Enhancing paracellular and transcellular permeability using nanotechnological approaches for the treatment of brain and retinal diseases

Asmaa Khalil, Alexandre Barras, Rabah Boukherroub, Ching-Li Tseng, David Devos, Thierry Burnouf, Winfried Neuhaus, Sabine Szunerits

Paracellular permeability across epithelial and endothelial cells is, in large part, regulated by apical intercellular junctions also referred to as tight junctions (TJs). These junctions contribute to the spatial definition of different tissue compartments within organisms, separating them from...

Detection and imaging of BVIDs in composite plates

Pierre Goislot, Guillemette Ribay, Emmanuel Moulin, Lynda Chehami

Composite materials are increasingly used in the aerospace industry. However, they may be subjected to Barely Visible Impact Damages (BVIDs). BVIDs can occur during maintenance phases or during flight and are almost impossible to detect with the naked eye. Although very small, these defects greatly...

Low Dielectric Filling Factor Millimeter-Wave Photonic Crystal Resonator Micromachined From NTD High-Resistivity Silicon

Stephen Hanham, Jan-Hendrik Buchholz, Horst Fischer, Uwe Gollor, Jonas Lehmke, Wolfgang Wischmann, Indra Ghosh, Enrico Lia, Benjamin Walter, Fuanki Bavedila, Marc Faucher, Andrew Gregory, Leif Jensen, Rüdiger Follmann

This article introduces a millimeter-wave electromagnetic (EM) bandgap (EBG) resonator, commonly referred to as a photonic crystal (PC) resonator (PCR), designed for use in a 45-GHz ultralow phase noise MMIC oscillator. The novel 2-D slab PCR design utilizes a higher order resonant mode, which has...
