Scientists uncovered rare hexagonal silicon forms (2H, 4H, 6H) created by stress and heat, challenging assumptions about this key electronic material. This is not the first time hexagonal silicon has ...

Researchers have synthesized millimetre-scale hexagonal diamond, a crystal structure so elusive that many physicists doubted ...

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 ...

Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder.

This story was updated on Oct. 15, 2019, to correct the statement that the hydrides overlap well with filled palladium d orbitals. The magnesium ligands are what interact with palladium's d orbitals.

After decades of debate, researchers say that they have found the clearest evidence yet for this rare form of carbon ...

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 ...

Chinese scientists claim to have created the long theorised hexagonal diamond, stronger than the real thing, and only found ...

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 ...

(Phys.org)—Virtually all semiconductors used in today's electronic devices are made of silicon having a cubic crystal structure, as silicon naturally crystallizes in the cubic form. In a new study, ...
