A multi-institutional team has directly observed electron hopping in iron oxide particles, a phenomenon that holds huge significance for a broad range of environment- and energy-related applications.

Rust – iron oxide – is a poor conductor of electricity, which is why an electronic device with a rusted battery usually won't work. Despite this poor conductivity, an electron transferred to a ...

An illustration shows the structure of epsilon-iron(III) oxide, an atomically thin material that is stable, stackable and unlike other iron oxides retains its unique magnetic properties at room ...
