In our previous studies, we have found the synergistic combinations of stabilizers which follow different mechanisms of stabilization and are approved for food contact applications. The present attempt is to test the potentials of those systems in stabilizing γ-sterilized low-density polyethylene (LDPE). The results were discussed by comparing the stabilizing efficiency of mixtures with and without...
A layered Aurivillius-type solid electrolyte, formulated as BiNi0.20 − xAlxVOX (Bi4Ni 0.2 − x(II) Al x(III) V1.8O10.7 + (x/2); 0 ≤ x ≤ 0.20) was synthesized by the standard solid-state reaction. The influence of Al substitution for Ni on the relationship between the phase stability and electrical performance in the parent bismuth vanadate was investigated by combining results obtained from...
Samples of Co–Ni double substituted bismuth vanadate, BICO0.20−xNIxVOX (Bi4Co0.20 − x(III)Nix(II)V1.8O10.8 − (x/2) − δ;0 ≤ x ≤ 0.20) were synthesized by standard solid state reactions. The influence of Ni substitution for Co on phase stabilization and oxide-ion performance have been investigated using X-ray powder diffraction, differential thermal analysis, and AC impedance spectroscopy....
Electrical conductivity of TiO2 doped with CaO has been measured at different temperatures for various molar ratios. The conductivity after initially remaining constant till about 140 °C increases with temperature due to the migration of vacancies created by doping. After attaining a maximum value at 240 °C, conductivity decreases due to the collapse of fluorite framework. A second rise in conductivity...
