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 ...

In 1967, a hexagonal form of diamond, later named lonsdaleite, was identified for the first time inside fragments of the Canyon Diablo meteorite, the asteroid that created the Barringer Crater in ...

Scientists have offered new insights into the origin of diamonds in ureilites (a group of stony meteorites). These diamonds most likely formed by rapid shock transformation from graphite (the common ...

Can copper be turned into gold? For centuries, alchemists pursued this dream, unaware that such a transformation requires a nuclear reaction. In contrast, graphite—the material found in pencil ...
