Abstract Professor John B. Goodenough started his research on perovskite‐type oxides
working on random‐access memory with ceramic [La, M (II)] MnO3 in the Lincoln Laboratory …

Producing indispensable hydrogen and oxygen for social development via water electrolysis
shows more prospects than other technologies. Although electrocatalysts have been …

Although both A-and B-site cations have the same simple cubic topology in the perovskite
structure they typically adopt different patterns of chemical order. As a general rule B-site …

Optical conductivity measurements on the perovskite-related oxide CaCu3Ti4O12 provide a
hint of the physics underlying the observed giant dielectric effect in this material. A low …

The oxygen evolution reaction (OER) is a key bottleneck step of artificial photosynthesis and
an essential topic in renewable energy research. Therefore, stable, efficient, and economical …

ACu3M4O12 phases crystallize in perovskite-related structure (space group: Im3). Dielectric
constants for ACu3Ti4O12 phases are found to be much higher than expected based on the …

Abstract Changes of valence states in transition-metal oxides often cause significant
changes in their structural and physical properties,. Chemical doping is the conventional …

Magnetic oxides show a variety of extrinsic magnetotransport phenomena: grain-boundary,
tunnelling and domain-wall magnetoresistance. In view of these phenomena the role of …

Remolding the reactivity of metal active sites is critical to facilitate renewable electricity-
powered water electrolysis. Doping heteroatoms, such as Se, into a metal crystal lattice has …

Quadruple perovskite oxides AA′ 3 B 4O12 demonstrate a rich variety of structural and
electronic properties. A large number of constituent elements for A/A′/B-site cations can be …
