Electrochemical Lithium Insertion into TiO 2 Anatase ALD Thin Films for Li‐Ion Microbatteries: An Atomic‐Scale Picture Provided by Raman Spectroscopy

Ankush Bhatia, Maxime Hallot, Clément Leviel, Pascal Roussel, Jean Pierre Pereira-Ramos, Christophe Lethien, Rita Baddour-Hadjean

Electrochemical lithium (de)intercalation in an atomic layer deposited (ALD) TiO2 anatase thin film deposited on a planar Si /Al2O3/Pt substrate is investigated by Raman spectroscopy. An initial discharge capacity of 63 µAh cm−2 µm−1 (0.5 Li+ mole−1) is reached at C/10 rate, which increases up to...

Deep Reinforcement Learning to Improve Vehicle-to-Vulnerable Road User Communications in C-V2X

Andy Triwinarko, Zoubeir Mlika, Soumaya Cherkaoui, Iyad Dayoub

In this paper, we study the problem of optimizing the performance of vehicle-to-everything (V2X) using deep reinforcement learning techniques while sharing the spectrum between vehicle-to-infrastructure (V2I) links and vehicle-to-vulnerable road users (V2VRU) links in Cellular V2X (C-V2X). The...

Zak Phase and Topological Tamm States Between Two Photonic Comb Structures

Soufyane Khattou, Yamina Rezzouk, Madiha Amrani, Mohamed El Ghafiani, El Houssaine El Boudouti, Bahram Djafari-Rouhani

We investigate the existence of Tamm states at the interface between two one-dimensional (1D) photonic crystals (PCs) through an analysis of local density of states (LDOS) using the Green’s function method. The PCs are made of a comb-like structure consisting of stubs grafted periodically along a...

Improvement of Silicon Nanowire-Based Photovoltaic Solar Cell with the Integration of CIGS Quantum Wells

Meriem Safi, Abdelkader Aissat, Houcine Guesmi, Jean-Pierre Vilcot

The present work focuses on the modeling and simulation of a new photovoltaic solar cell based on a CIGS/Si nanowire. The study of the effect of inserting quantum wells in a nanowire structure for different characteristic parameters has been done to evaluate the potential of the confinement...

Behavior of conducting polymer-based micro-actuators under a DC voltage

L. Seurre, H. Aréna, Sofiane Ghenna, Caroline Soyer, Sébastien Grondel, Cedric Plesse, G.T.M. Nguyen, Eric Cattan, Frédéric Vidal

Conducting polymer-based micro-actuators are of great interest in soft MEMS as they exhibit large strains and forces in response to electrical stimulation. To date, these micro-actuators have very often been characterized by applying low frequency voltage to extract the electromechanical...

Study of reaction-diffusion controlled mass transport in stopped-flow fluidics for spatiotemporal multiplexing

Marcel Tintelott, Pradnya Gharpure, Yannick Coffinier, Xuan Thang Vu, Alexis Vlandas, Sven Ingebrandt, Vivek Pachauri

Integration of biochemical reaction networks (BRNs) with biosensor platforms has emerged as a technological niche overcoming challenges related to the loss of sensitivity and selectivity in biological media. Optimal operation of BRNs in microfluidics requires control over reaction-diffusion...
