they would find helium atoms worked into the crystal structure (known as a lattice) of iron. And indeed, upon inspection, helium atoms were found between iron atoms in the lattice structure—the ...

Crystal structure of Na2He, resembling a three-dimensional checkerboard. The purple spheres represent sodium atoms, which are inside the green cubes that represent helium atoms.

Helium, the gas that fills up our balloons, has a reputation as a chemistry lightweight—as an element that doesn’t react with much of anything. Researchers say they’ve used high pressure to ...

“Unlike helium-4, which is produced through radioactivity ... “Our calculations also revealed a dynamically stable crystal structure, supporting our experimental findings.” Altogether, this ...

China and the UK used a search algorithm to look for iron- or magnesium-based materials that have lower energies when helium is incorporated into their crystal structures. These two elements were ...

At very low temperatures, helium can be solid and a perfect ... for example by orienting the structure of one half of the crystal in a different direction to the other half. They performed this ...

Captured within the cavities of a porous glass disk, frozen helium has coalesced into ... to flow like a liquid yet maintain its solid crystal structure, says team leader Moses H.W. Chan of ...

Further analysis confirmed helium’s incorporation into iron’s crystal lattice ... long-standing ideas about the planet’s internal structure and history, and may even reveal details of ...

They also used infrared spectroscopy to determine their structures. Kuma and co-workers used an ultracold environment to make the isomers. The water molecules in the helium droplets cooled rapidly ...

The helium is put into a state where all the magnets point in the same direction, creating what is called magnon. The researchers observed a quasitime crystal, formed by the magnon slowly ...
