Prof Yashima and his team note that the crystal structure of Ba7Nb3.9Mo1.1O20.05 contains oxygen-deficient layers (c' in Fig. 2a and Fig. 2c) and that its high oxide-ion conductivity is ...

The interstitial oxygen O5 and the O1-O5 oxide-ion interstitialcy diffusion of Ba7Nb3.9Mo1.1O20.05 (IMAGE) _Tokyo Institute of Technology ...

Additionally, the analyses and calculations showed that the Mo ions preferentially occupied the oxygen-deficient layers responsible for the oxide-ion conduction.

Rubidium could be the next key player in oxide-ion conductors. Researchers have discovered a rare rubidium (Rb)-containing oxide-ion conductor with exceptionally high conductivity. Identified ...

When built into a layered 2D structure on graphene, this ratio produces long-range, uniform strain across the material. That strain helps the cathode resist breakdown during repeated cycling. The ...

The mediation of oxygen exchange by these stuffed structures suggests a new view of the relationship between structure and reactivity at the oxide/solution interface.
