A synergistic experimental–theoretical study of radiation attenuation in locally manufactured Iraqi glasses

Nuclear Engineering and Technology
In this context, we examine the physical, structural, and gamma-ray shielding properties of six Iraqi traditional glass samples (S1–S6). The elemental composition was analyzed using Energy Dispersive X-Ray Fluorescence (EDXRF) while the Archimedes ...

Photovoltaic Effect in a III‐IV‐V Compound Semiconductor

Progress in Photovoltaics: Research and Applications, EarlyView.
A large reduction of the GaAs band gap is obtained with incorporation of 6.5% Ge during epitaxy without introducing extended defects or composition inhomogeneity. Heterojunction solar cell devices were fabricated with 0.76‐V open circuit voltage and an internal quantum efficiency above 40% at energies below the bandgap of the GaAs emitter.

A detailed study on the physical, mechanical, structural and gamma ray shielding properties of Al2O3–Na2O–SiO2–B2O3–Bi2O3glass system

Journal of Science: Advanced Materials and Devices
The density, boron–boron separation, and molar volume of 4Al2O3–12Na2O-(18-x)SiO2-(64-x) B2O3-(2+2x)Bi2O3 (where x = 2, 4, 6 and 8 mol%) are increasing with the addition of Bi2O3. The addition of Bi2O3 results in an open network structure.

From analytical to data‐driven: multi‐method optimization of a bendable mirror system for dynamic focusing

Journal of Synchrotron Radiation, EarlyView.
A small‐radius‐of‐curvature bendable mirror system is developed for dynamic focusing in X‐ray free‐electron laser and synchrotron radiation beamlines, and a transfer‐learning neural‐network and differential‐evolution framework is used for force‐to‐shape modeling and inverse optimization.
