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.

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 ...

The global hydrodesulfurization catalyst market forecast was valued at $2.64 billion in 2020, and is projected to reach $3.66 billion by 2028, growing at a CAGR of 4.30% from 2021 to 2028.

In compounds they occur as double-atoms, that is e. g. Pr2Cl, and not PrCls and their structure indicates therefore tetra-valency: GROUP O—Noble Gases or Inert Elements: He, Ne, Ar, Kr ...

Heavier noble gases can form compounds at experimentally accessible pressures, but the reactivity of helium – especially below the 350GPa found at the centre of the Earth – was thought to be almost ...

Beyond helium, this discovery raises a bigger question: could other noble gases, like neon or hydrogen, also be stored in Earth’s core? If so, this could help explain the origins of Earth’s ...

The potential of Ni-Al intermetallics in IR thermophotonics is examined, highlighting their thermal stability and optical ...

Maura Healey, now in her third year, has staked her legacy on an ambitious infrastructure overhaul—an $8 billion transportation plan unveiled with fanfare on March 18, 2025, in Lenox, promising to ...
