Copper iodide nanoparticles supported on modified graphene-based nanocomposite catalyzed CO2 conversion into oxazolidinone derivatives

Maryam Mirza-Aghayan, Mahdi Alizadeh, Rabah Boukherroub

We report on the preparation of copper iodide nanoparticles (NPs) immobilized on vitamin B3-modified graphene (CuI/GO-VB) nanocomposite and its application for the synthesis of oxazolidinone compounds using a remarkable carboxylative cyclization method via the reaction of arylacetylene, aldehyde…

Photonic THz mixers based on iron-doped InGaAs embedded in a plasmonic microcavity

Charbel Tannoury, Victor Merupo, Giuseppe Di Gioia, Vanessa Avramovic, David Troadec, Jean-François Lampin, Guillaume Ducournau, Steffen Breuer, Björn Globisch, Stefano Barbieri, Robert B Kohlhaas, Emilien Peytavit

We present an optoelectronic mixer for the terahertz (THz) frequency-domain based on an iron-doped InGaAs layer integrated in a plasmonic microcavity. We show that this structure, under 1550-nm-wavelength illumination, allows for more than 70% absorption efficiency in a 220 nm-thin InGaAs absorber…

Analysis of Airgaps for Off State Capacitance Reduction in SOI CMOS RF Switches

Daniel Gheysens, Alain Fleury, Stephane Monfray, Frederic Gianesello, Philippe Cathelin, David Troadec, Jean-François Robillard, Emmanuel Dubois

This article analyses the introduction of airgaps in the interconnect network of SOI-CMOS based RF switches to significantly reduce the off-state capacitance COFF without degrading the on-state resistance RON. Based on the 130 nm node of an existing RF-SOI-CMOS technology, an accurate COFF…

Improving Date Fruit Sorting with a Novel Multimodal Approach and CNNs

Ibtissam Boumaraf, Abdelhamid Djeffal, Sarah Setta, Abdelmalik Taleb-Ahmed

Date fruit is a beloved and widely consumed food in the Middle East and North Africa, and its popularity is growing globally. However, sorting these fruits can be a time-consuming and labor-intensive process, particularly when done manually. To address this challenge, we have proposed an innovative…

Time-resolved self-heating temperature measurements of AlInN/GaN HEMTs using CeO2 Raman micro-thermometers

R. Strenaer, Y. Guhel, C. Gaquiere, B. Boudart

The DC and RF electrical performance and reliability of GaN-based transistors depend on their thermal behavior. Therefore, measuring the self-heating temperature of these devices under real operating conditions with high accuracy is an important and challenging issue. For these reasons, we present…

Mechanical Enhancement of the Strain‐Sensor Response in Dimers of Strongly Coupled Plasmonic Nanoparticles

Najat Ahmidayi, William d'Orsonnens, Thomas Maurer, Gaëtan Lévêque

Due to their particular optical and mechanical properties, plasmomechanical devices have become choice candidates in strain sensing applications. Using numerical simulation, a plasmomechanical system consisting of two gold nanoparticles with different shapes and separated by a small gap, deposited…

Optimizing convolutional neural networks architecture using a modified particle swarm optimization for image classification

D. Elhani, A.C. Megherbi, A. Zitouni, F. Dornaika, S. Sbaa, Abdelmalik Taleb-Ahmed

Although Convolutional Neural Networks (CNNs) have been shown to be highly effective in image classificationtasks, designing their architecture to achieve optimal results is often challenging. This process is time consuming, requires significant effort and expertise, and is complicated by the large…
