Spectroelectrochemical study of carbon structural and functionality characteristics on vanadium redox reactions for flow batteries Open
The oxidation of V( iii ) to V( iv ) only occurs on a limited number of specific functional group sites and the outer-sphere electron transfer to oxidize V( iii ) only takes place at much more positive potentials.

Hydrogen spillover drives room temperature sensing on spark plasma sintered BaTiO<sub>3</sub> with Pt electrodes Open
Change in BaTiO 3 grain boundary resistance due to H 2 dissociation on platinum and spillover and reaction of hydrogen with BaTiO 3 surface hydroxyl species. This forms adsorbed water that desorbs to generate oxygen vacancies.
