Sentence examples for valence change from inspiring English sources

That of cerium is due to a valence change, while those in terbium and dysprosium are magnetic in origin.

Meanwhile, stability and deterioration as well as relative mechanisms of the VO2 coatings were also investigated by monitoring the valence change of the vanadium element.

Ceria has been used for catalyst support for long time due to its unique structural properties resulting from oxygen vacancies and reversible valence change (Ce4+ and Ce3+).

Results indicate that the fast valence change of nickel species mainly contributes the faradaic reaction of the active materials, while the cobalt species offer the high electronic conductivity and assist the charge transfer process.

On the other hand, for valence change memory (VCM) type of systems such as Pt/TiO2/Pt/Ti15 and Ta/TaOx/Pt11, it is widely accepted that the motion of oxygen anions (or equivalently the positive-charged oxygen vacancies) leads to valence changes of the metal (cations) and hence the resistance changes of the metal oxide materials.

First, three types of CeO2 ZrO2 (Ce:Zr = 1 1 molar ratio) compounds with different oxygen storage/release capacities and different structural properties were prepared, and the valence change of Ce as a function of temperature during oxygen release/storage processes was investigated.
