TL;DR: Using electron paramagnetic resonance, the motion of oxygen vacancies within the oxygen octahedron in perovskite BaTiO{sub 3} is observed via the alignment of oxygen vacancy-related defect dipoles induced by bias/heat combinations.
Abstract: Using electron paramagnetic resonance, the motion of oxygen vacancies within the oxygen octahedron in perovskite BaTiO{sub 3} is observed via the alignment of oxygen vacancy-related defect dipoles induced by bias/heat combinations. The vacancy motion is found to have an activation energy of 0.91 eV, in excellent agreement with the predicted. It is found that the onset of resistance degradation is also concurrent with oxygen vacancy motion. This result spectroscopically demonstrates that oxygen vacancy migration in the lattice is likely responsible for the observed degradation.

TL;DR: In this paper, the kinetics and mechanism of the oxygen evolution reaction at a series of RuO2/IrO2 mixed oxides in aqueous acid and alkaline solution has been examined using a variety of electrochemical methods.
Abstract: The kinetics and mechanism of the oxygen evolution reaction at a series of RuO2/IrO2 mixed oxides in aqueous acid and alkaline solution has been examined using a variety of electrochemical methods. Factors affecting the electrocatalytic activity have been elucidated and novel oxygen evolution mechanisms in terms of reactive oxyruthenium and oxyiridium surface groups are proposed.
