In a number of biological processes, iron-sulfur clusters play a vital role, where they act as cofactors to enzymes. Research now shows that cubic clusters can support unusual bonding states. This ...

Ohio University physicist Saw Wai Hla and his colleagues were able to scan a single iron atom hidden amid a complex molecule, something that’s never been done with an X-ray before. Extremely powerful ...

Left: Image of a ring-shaped molecular host that contains just one iron atom. Right: X-ray absorption spectrum of single atom detected at location B in the molecular ring. Spectrum matches that of ...

Nitrogen is crucial for all known life, but it is predominantly found in its most unreactive form, gaseous dinitrogen (N 2). The challenging process of nitrogen fixation, in which dinitrogen is ...

The iron Fe2+ atom embedded in a semiconductor exhibits a single non-degenerate ground state of zero magnetic moment. A team of scientists has demonstrated that by using sufficiently large strain it ...
