Oxygen vacancy distributions and dynamics directly control the operation of solid-oxide fuel cells and are intrinsically coupled with magnetic, electronic and transport properties of oxides. For ...

The atomic-scale local structures of ruthenium oxide were precisely engineered through controllable manipulation of oxygen vacancies (O v) via high-vacuum annealing. The optimized Ru-Ru and adjacent ...

A research team led by Professor Sang Uck Lee of the School of Chemical Engineering at SKKU in collaboration with Research team at Korea University and KIST(Korea Institute of Science and Technology), ...

Researchers directly observed bulk oxygen spillover in catalysts for the first time, revealing that a catalyst's interior can ...
