The present work aims to fabricate new inexpensive epoxy-based composites with a concentration described by the formula (90 − x)epoxy + 10Sb2O3 + xPbO, where x = 5, 10, 15, and 20 wt%. The impacts of the substitution of epoxy by PbO on the composit

The radiation shielding competence was examined for a binary glass system xLa2O3 + (1 − x) TeO2 where x = 5, 7, 10, 15, and 20 mol% using MCNP-5 code. The linear attenuation coefficients (LACs) of the glasses were evaluated, and it was found that L

According to the Makishema–Mackenzie model assumption, the dissociation energy and packing density for a quaternary TeO2-As2O3-B2O3-Li2O glass system were evaluated. The dissociation energy rose from 67.07 to 71.85 kJ/cm3, whereas the packing facto

In this research, we study the structure and radiation shielding performances of YBCO-123 ceramics doped with different oxides. Specimens were made using the solid-state reaction route. X-ray diffraction (XRD) results disclosed that the different cer

Optimum shape design solves a class of problems involving continuous mechanical components where the optimum shape (the shape of the boundary and the surfaces of the components) is determined. In this work, a computer code has been developed for anal
