Researchers have synthesized millimetre-scale hexagonal diamond, a crystal structure so elusive that many physicists doubted it could ever be produced in bulk. The material, also called lonsdaleite, ...

For a long time, scientists associated crystal structures with an ordered arrangement of atoms in a repeating lattice-like pattern, believing it to be the most stable configuration. However, by the ...

Researchers in China say they have produced hexagonal diamond, a long-disputed form of carbon that theory predicts could be ...

The HS-I, CS-I, and CS-II structures of hydrate correspond to the Z, A15, and C15 phases of the Frank-Kasper phase, respectively. With the discovery of HS-I, the primitive structures at the three ...

Mysterious hexagonal diamonds that don’t occur naturally on Earth have been discovered in four meteorites in north-west Africa. “It’s really exciting because there were some people in the field who ...

Sitting atop Saturn’s north pole is one of the Solar System’s most striking weather patterns: a rotating, color-changing hexagon slightly wider than Earth. A new study shows there’s another hexagon ...

Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder. Evidence of this was gathered over the past sixty years in meteorite ...
