Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

are naturally occurring rocks that contain metal or metal compounds in sufficient amounts to make it worthwhile extracting them.

In addition to direct applications, MOFs have been used as unique precursors for the construction of inorganic functional materials with unparalleled design possibilities, such as carbons, metal-based ...

The iron oxide is no longer a pure metal, it is a dull, dark-coloured, metal compound. When you burn magnesium in the air in the same way that the iron did, the magnesium reacts with oxygen to ...

They rely on so-called metal-organic framework compounds, which work much better than the materials commonly used to date. Even extremely low concentrations of per- and polyfluoroalkyl substances ...
