ThomX is a compact x-ray source based on Compton scattering, installed at IJCLab (Laboratoire de physique des 2 infinis-Irène Joliot-Curie) in Orsay. The machine uses a small electron storage ring and an intense laser pulse stored in a high-finesse optical cavity. This article describes the various subsystems of the machine and their initial result...
This paper delves into the indoor performance analysis of Perovskite/Silicon Tandem Solar Cells (PSSTC) through a detailed exploration utilizing numerically modeled energy band diagrams. The primary objective is to uncover the potential of PSSTC for solar energy conversion in indoor settings. Various tandem cell configurations are scrutinized under...
Radioisotopes are one of the essential cornerstones of modern medicine. They serve both diagnostic and therapeutic purposes. These radioisotopes are mainly produced using charged particle accelerators such as cyclotrons. In this paper, we present a description of a compact high-field superconducting magnet as it is considered the most important par...
With the increase in laser power and finesse of optical cavities over the last decade, laboratory-size Compton sources are very promising. These sources produce X-rays through interactions between relativistic electrons and laser photons and, in term of brightness, fall between large synchrotron facilities and classical laboratory X-ray sources. Th...
Hydrogen energy has attracted a lot of interest as a renewable and sustainable energy source, but there are a few technical impediments associated with its storage. Solid-state hydrogen storage is a catching-on and intensively researched alternative to other methods for storing hydrogen. Perovskite hydrides exhibit the ability to store solid-state...
In this paper, structural, electronic properties, optical spectra, stability, as well as the quantum efficiency of bulk, monolayer and two different stacking heterostructure configurations (XY2/XY2) of dichalcogenide compounds XY2 (where X = Mo or W and Y = S or Se) were performed using density functional technique. Our findings reveal the strong c...
In this work, different ion co‐doped Mg 1‐x Al 2 O 4 nanophosphors, coded as M 5Cr‐5La A, M 5Cr‐5Cu A, M 0.07Si‐0.03Ce A, and M 0.05Ti‐0.05La A, where 5Cr‐5La, 5Cr‐5Cu, 0.07Si‐0.03Ce, and 0.05Ti‐0.05La representing the added ions (mol%), were prepared using the sol–gel method. Phase structure, transmission electron microscope (TEM) images, and elem...
This paper evaluates the compatibility of five different machine learning (ML) algorithms for analyzing datasets extracted from solar cell devices. The selected ML algorithms span a range of complexity, from linear regression and polynomial regression models to random forest (RF), neural network, and a hybrid version of the latter two. The algorith...
This paper introduces a thorough simulation study, based on SCAPS, into the realm of B-γ CsSnI3 perovskite solar cells (PSCs). The work encompasses an array of critical aspects ranging from material properties to device physics strategies and performance enhancement techniques. The core objective of this study revolves around the meticulous optimiz...
In this article, a sol–gel route was employed to prepare nanophosphor materials including Ca9-x CrxAl (PO4)7 series (where 0.05 ≤ x ≤ 0.5 (mol%)). All subseries were irradiated to a γ- test dose of 5 Gy and the thermoluminescence (TL) response of Cr-activated (0.1 mol%) Ca9Al (PO4)7 sample has the best TL response and was chosen for investigations....
Green synthesis of NPs evades many of the deleterious aspects by permitting the synthesis of nanoparticles at relatively low temperatures, pH and pressure, all at a significantly lower cost and short time. A bottom-up approach is used for the synthesis of silver nanoparticles formed due to the reduction of silver ions because of the existence of th...
Solar cell technologies are pivotal in the transition towards sustainable energy sources. This paper delves into the design and optimization of CBTSSe solar cells for efficient indoor energy harvesting. The tunable bandgap nature of CBTSSe aligns well with the emission spectra of indoor LED lighting, making it a promising candidate for such applica...
The physical characteristics of SZr2N2 and BaAg2S2 Zintl phases have been explored by utilizing the full-potential augmented plane wave (FP-LAPW) method with the combination of modified Becke-Johnson (mBJ) approximation. The negative formation energies and phonon modes with positive frequencies endorsed the stability of both compounds. The electron...
The energy conversion efficiency is one of the attributes which make Heusler alloys an extraordinary candidate for thermoelectric applications. In this paper, we have examined the electronic structure, elastic, optical and transport characteristics of full Heusler Na2TlX (X=Bi, Sb) alloys using DFT. The electronic properties are analyzed by utilizi...
