Zinc oxide nanowires: Hydrothermal synthesis, and structural, electrical, and piezoelectric characterizations

Imen Ben Khaled, Elhadj Dogheche, Philippe Leclère

Zinc oxide (ZnO) nanowires (NWs) are attractive lead-free piezoelectric nanomaterials with wide range of applications. In this work, vertically aligned ZnO NWs were synthesized on sputtered ZnO seed layers via a hydrothermal process. We investigated the effects of seed layer and NWs synthesis…

A Novel Time-Frequency Approach for Frequency-Hopping Signal Blind Estimation

Ali Khalaf, Arthur Louchart, Sébastien Houcke, Ray Abdo, Laurent Clavier

<div><p>The estimation of frequency-hopping spread spectrum (FHSS) signals is essential for the analysis and detection of communications in dynamic and challenging environments. This paper presents a novel approach based on time-frequency analysis using a two-dimensional Fourier…

Energy-Efficient RIS-aided Uplink Cell-Free Massive MIMO-NOMA

Mohamad Ousseily, Joumana Farah, Matthieu Crussière, Joseph Doumit, Charbel Abdel Nour, Eric Pierre Simon

<div><p>Cell-free massive MIMO (CF-mMIMO) promises uniform coverage for beyond-5G networks but faces critical energy efficiency (EE) challenges in dense and uncoordinated Internet-of-Things deployments. This paper addresses uncoordinated uplink transmission where devices transmit…

Characterization of Healthy and Faulty Networks using Structured Transferometry Residuals

Ameer Ahmadie, Virginie Degardin, Vincent Cocquempot

This paper presents the characterization of healthy and faulty situations in Y-shaped communication networks using a transferometry-based diagnostic method. The study focuses on soft faults, defined as small degradations that do not significantly impact data or power transmission in networks.…

Microfabricated vapor cells with tunable buffer gas mixtures using laser-actuated break-seal reservoirs

Clément Carlé, Gabriel Faure, Andrei Mursa, Shervin Keshavarzi, Quentin Tanguy, Emmanuel Klinger, Vincent Maurice, Rodolphe Boudot, Nicolas Passilly

Microfabricated cells are the core component of a wide variety of chip-scale atomic devices, such as clocks or magnetometers [1]. In those instruments, the cell is generally filled with a pressure of buffer gas. The presence of buffer gas reduces the atom-wall collision rate, enhances the atomic…

Fundamental thermovisco mechanical interactions governing the acoustic response of laser-excited nanoparticles

Stefano Giordano, Michele Diego, Francesco Banfi, Michele Brun

In this work, we investigate the thermoacoustic generation and propagation of spherical waves in a viscous fluid induced by a laser-heated spherical particle. Periodic laser excitation gives rise to two coupled mechanisms of acoustic emission. Heat transfer from the particle to the surrounding…

Coexistence and interplay of Fabry–Pérot and twin Friedrich–Wintgen bound states in the continuum in a plasmonic double T-cavity

Amina Rezzouk, Soufyane Khattou, Madiha Amrani, Adnane Noual, El Houssaine El Boudouti, Bahram Djafari-Rouhani

Bound states in the continuum (BICs) are typically investigated in terms of distinct formation mechanisms, such as symmetry-protected (SP), Friedrich–Wintgen (FW), or Fabry–Pérot (FP) BICs. However, their coexistence and mutual interaction within a single plasmonic architecture have not been…

Impact of iodine-induced nonplanarity on the vibrational and electronic properties of a triphenylene derivative: A combined experimental and DFT study

Ahmed Hewail, David Guérin, Christophe Krzeminski, Eric Faulques, Nataliya Kalashnyk

We present a molecular study combining Raman, infrared, and UV–visible absorption spectroscopy with density functional theory (DFT) calculations to investigate triphenylene and its iodinated derivative, 1,5,9-triiodotriphenylene. The results provide a detailed comparison of their vibrational and…

Electrostatic force regularization for neural structured pruning

Abdesselam Ferdi, Abdelmalik Taleb-Ahmed, Amir Nakib, Youcef Ferdi

The demand for deploying deep convolutional neural networks (DCNNs) on resource-constrained devices for real-time applications remains substantial. However, existing state-of-the-art structured pruning methods often involve intricate implementations, require modifications to the original network…
