Gamma radiation shielding by titanium alloy reinforced by polymeric composite materials J. Radiat. Res. Appl. Sci. (IF 1.7) Pub Date : 2023-12-21 Saad Aldawood, Nassar N. Asemi, Hamoud Kassim, Aziz A. Aziz, Waseem S. Saeed, Abdel-Basit Al-Odayni
The Ti-6Al-4V alloy (TAV) has several desirable properties, including high density, strength, low corrosion, biocompatibility, and flexibility. Based on these attractive features, we study the gamma radiation shielding capabilities of a titanium alloy TAV strengthened by polymeric composite materials. Examining the TAV alloy demonstrates discernible X-ray diffraction (XRD) peaks corresponding to specific

Simple parameterization for refractive indices of semiconductors J. Radiat. Res. Appl. Sci. (IF 1.7) Pub Date : 2023-12-13 Ali A. Alkathiri
In this research paper, we suggest a simple parameterization for the refractive indices n of semiconductors. Our suggested model is a rational function of energy gap Eg. The aim of this model is to describe the refractive index for semiconductors at low and high energy gap values. We fitted this model to a data set of experimental data of n with Eg, at 0–10.5 eV. We obtained excellent predictions for
