Scientists have captured the first-ever image of individual atomic oxygen dissolved in water, using an advanced laser approach that reveals previously unknown behaviors of this highly reactive species ...

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 ...

Fe-N 4 is a typical active site in Fe-N/C catalysts with maximum atomic utilization and a well-defined structure. However, its high symmetry limits further electronic structure optimization and ...
