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.

Researchers at the Universities of Amsterdam and Zurich have developed a molecular system for the controlled release of iron.

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

"We concluded that iron oxides are 'catalytic traps' because they catalyze the reaction to remove phosphate from organic compounds but trap the phosphate product on the mineral surface," Aristilde ...

The diamond anvil crushed iron and helium together under conditions mimicking those inside the Earth, to create a new compound. These compounds remained stable when pressures were reduced.

has been formed because the iron and sulfur atoms are now chemically bonded together. The new substance is called a compound. Other compounds are made from different combinations of atoms ...

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 ...

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 ...

Researchers named the compound “berkelocene” because it is comparable to the compound “uranocene,” a uranium-containing ...

Oxygen in the air combined with impurities in the iron to produce carbon dioxide and other compounds that vented out the top of the furnace as gases. Enough heat was created by these reactions to keep ...
