The discovery that inert helium can form bonds with iron may reshape our understanding of Earth’s history. Researchers from ...

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.

But in this case, they were surprised to find the crushed iron compounds contained as much as 3.3% helium, about 5,000 times higher than previously seen. Hirose suspects this is at least in part ...

These results suggest that similar reactions between helium and iron may have occurred within Earth’s core shortly after its formation, trapping much of the primordial helium-3 in the material that ...

Iron can form compounds with helium at pressures as low as 5GPa – about 50,000 atmospheres – researchers in Japan report.

Iron is the main ingredient in various forms ... Carbon (C): Carbon, a nonmetallic element, forms a number of organic and inorganic compounds and can be found in coal, petroleum and limestone.

The team from the Collaborative Research Center (CRC) CataLight at the Universities of Ulm and Jena has now shown that iron ...
