Iron valence state and local environment in a set of fibrous diamonds from Brazilian and Zairean placers were investigated using X-ray Absorption and Mössbauer spectroscopies. It is shown that the ...

Scientists have developed a way to grow iron-oxidizing bacteria using electricity instead of iron, an advance that will allow them to better study the organisms and could one day be used to turn ...

Cytosolic and nuclear iron-sulfur (Fe-S) proteins play key roles in processes such as ribosome maturation, transcription and DNA repair-replication. For biosynthesis of their Fe-S clusters, a ...

Rust—iron oxide—is a poor conductor of electricity, which is why an electronic device with a rusted battery usually won't work. But electrons do move through iron oxide—on seemingly geologic ...
