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

Molten carbon can form into either diamond or graphite. A new study shows how graphite can sometimes form even under conditions that should lead to diamond. (Getty Images) The graphite found in your ...

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

Diamonds form deep within the Earth's mantle, around 250 kilometers below the surface, where immense pressure (up to 10 GPa) and temperatures (around 2,200 °C) compress carbon into diamonds over ...

Research teams from Wuhan University and the China University of Geosciences (Wuhan) have revealed new insights into the formation mechanism of nitrogen-vacancies (NV) centers in type-Ib diamonds, a ...

Researchers have succeeded in creating a rare type of diamond, known as lonsdaleite or hexagonal diamond. This material, whose hardness could surpass that of conventional diamonds, opens new ...

Paving the way to a dry process with less environmental impact Tools coated with diamond film (diamond-coated tools) are used for difficult-to-machine materials such as CFRP. In the manufacture of ...
