Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

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.

Scientists from Japan and Taiwan recently demonstrated that helium, the second-lightest element, can integrate into iron's crystal structure under intense conditions. Using a laser-heated diamond ...

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

These compounds remained stable when pressures were reduced. Further analysis confirmed helium’s incorporation into iron’s crystal lattice. Researchers from Japan and Taiwan reveal for the ...

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.

"In this case, we crushed iron and helium together under about 5–55 gigapascals of pressure and at temperatures of 1,000 Kelvin to nearly 3,000 Kelvin. Those pressures correspond to roughly ...

Characterization of surface effects, crystal size and grain formation was ... with the longest exciton lifetime for film quenched with helium gas followed by nitrogen and argon gases, respectively ...
