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 ...

A team of researchers has for the first time observed and recorded the creation of hexagonal diamond under shock compression, revealing crucial details about how it is formed. The discovery could help ...

Researchers have produced nearly pure hexagonal diamond, a material long theorized to be harder than conventional diamond, by compressing and heating graphite under extreme conditions. The resulting ...

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

A Chinese research team has produced bulk hexagonal diamond, a crystal structure long theorized to be harder than ...

The graphite found in your favorite pencil could have instead been the diamond your mother always wears. What made the difference? Researchers are finding out. How molten carbon crystallizes into ...

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

Molten carbon can crystallize into diamond or graphite, but it has been difficult to study this process. New simulations show that graphite can sometimes "hijack" the pathway that would lead to ...
