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 ...

Previous studies had assumed that metallization in FeO was associated with a change in its crystal structure. This result means that iron oxide can be both an insulator and a metal depending on ...

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 ...

regulates the expression of three genes through the progressive degradation of its [4Fe–4S] cluster on nitric oxide (NO) exposure. We report the 1.95 Å resolution crystal structure of dimeric ...

The researchers believe this could explain the previous lower estimates for iron oxide’s melting point – rather than detecting the melting of the whole crystal structure, those experiments were seeing ...

A Good Place to Settle Down 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 ...

The so-called chlor-iron process combines two known electrochemical methods. One reduces iron oxide into iron in a sodium hydroxide electrolyte. The other is the well-known chlor-alkali process ...
