The advancement of industry and the hastening of urbanization have led to serious
problems associated with the emanation of various harmful and lethal gases, which are a …

The optical and electrical properties are the two important dimensions of Indium oxide and
its derivatives (indium tin oxide) and were well studied to understand the origin of wide …

In this paper, first-principles calculations based on density functional theory (DFT) were used
to determine TM (TM= Fe, Ni, Co) and Cd impurity locations in the In 2 O 3 host structure …

Based on ab initio band-structure calculations we formulate a general theoretical method for
description of the temperature dependence of an electric-field gradient in solids. The method …

The Pechini sol-gel method has been employed for the synthesis of pure and (181 Hf→) 181
Ta-doped Y 2 O 3 nanopowders. We performed a structural characterization from the micro …

Doping semiconductor oxides with trace amounts of non-native elements can improve their
properties such as bandgap and conductivity. The lack of local techniques makes the …

Nesta dissertação foi investigado a origem do Gradiente de Campo Elétrico (EFG) no CeO2
