In this method, the particles are treated with ammonia gas to get the nitrogen into the crystal structure. Alternatively, iron oxide can be mixed with ammonium nitrate in a planetary ball mill ...

New experiments and supercomputer computations have revealed that iron oxide ... Previous studies had assumed that metallization in FeO was associated with a change in its crystal structure.

Nano-Holes and Travelling Iron. The iron oxide (Fe3O4), on which the platinum particles rest, has remarkable properties. It has a regular crystal structure and each atom has its well-defined ...

NsrR is a bacterial transcriptional regulator that acts as a nitric oxide (NO) sensor. Here, the authors present the crystal structure of NsrR, which reveals an unusual Fe-S cluster coordination ...

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).

Iron Oxide May Explain Mysterious Anomalies Under the Earth’s Surface Iron oxide’s melting point is much higher than previously thought, ... rather than detecting the melting of the whole crystal ...

The key to success is a slight deformation of the iron-oxide crystal structure. The oxygen atoms of the topmost layer are not aligned in perfectly straight lines, they are bent into wiggles by the ...

Future Market Insight projects that the global iron oxide market share will grow at a CAGR of 4.1% to reach USD 4.3 billion ...

Tiny magnetic iron crystals in the brain may be linked to the development of Alzheimer's disease, suggests preliminary research. If further work confirms the hypothesis, it could be possible to ...

The researchers at the TU Vienna found a special kind of iron-oxide surface, which locks the single gold atoms in place. The oxygen atoms form wiggly lines on the surface, due to the atoms below ...
