Hexagonal diamonds are formed when graphite is subjected to strong impact and heat, such as due to a meteorite impact. While ordinary diamond has a structure called cubic, hexagonal diamond is ...

Hexagonal boron nitride has a layered crystalline structure in a hexagonal lattice arrangement composed of alternating boron and nitrogen atoms held together by strong covalent bonds. This structure ...

The University of Cambridge, Plessey Semi and Anvil Semi have got together to apply a new material to lighting LEDs – cubic GaN, also known as 3C GaN. The standard material for lighting LEDs is GaN ...

A 40-atom gold nanocluster breaks from gold's signature dense packing, forming square atomic planes with a central channel that accelerates electron relaxation about 80x.

In chemistry, structure is everything. Compounds with the same chemical formula can have different properties depending on the arrangement of the molecules they’re made of. And compounds with a ...

For the first time, researchers have hard evidence that human-made hexagonal diamonds are stiffer than cubic diamonds found in nature and often used in jewelry. Hexagonal diamonds have been found at ...

New research indicates that a rare form of diamond may originate in the burbling cores of distant worlds, arriving on Earth thanks to violent cosmic collisions. According to a team of scientists in ...

Scientists have created the first sizable meteorite diamond — also known as lonsdaleite or hexagonal diamond — a material predicted to be even harder than the diamonds normally found on Earth. The ...
