An international group of researchers including Russian scientists from the Moscow State University has been studying the behaviour of the recently-discovered Fe4O5, iron oxide.

The study also delivered another, more unexpected, result. At atmospheric pressure, iron oxide samples do have atomic-scale defects in them. For every 100 oxygen atoms, there are only around 95 iron ...

New experiments and supercomputer computations have revealed that iron oxide undergoes a new kind of transition under deep Earth conditions. ... but without a change to its structure.

Iron oxide (formula: Fe3O4) nanoparticles are "superparamagnetic," meaning that they turn magnetic only in the presence of an external magnetic field. In contrast, ...

Help with chemical potential formula in a mixture. Jun 16, 2025. ... Iron oxide 'oxygen sponge' doubles green hydrogen production efficiency by targeting atomic-level active sites.

A new low-temperature electrochemical process that produces metallic iron from iron oxide and saltwater could help clean up steelmaking’s act (Joule 2024, DOI: 10.1016/j.joule.2024.01.001).

Their research supported evidence for the "Levantine Iron Age geomagnetic Anomaly," a time when the planet's magnetic field was surprisingly strong around what is now Iraq between 1050 and 550 B.C.
