Elucidating the valence change mechanism in oxides memristors remains challenging due to subtle oxygen vacancy migration. Here, we quantify individual oxygen vacancies and observe their dynamic ...

a) Atomic structure of the four molecules with different first-shell Co–N coordination considered in this study and (b) schematic illustration of the heterogeneous molecular catalysts (HMCs) prepared ...

Tiny changes at the atomic scale can determine the future of clean energy. In a new study, Tohoku University researchers have revealed how the precise coordination environment surrounding a single ...
