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 ...

“These findings resolve the long-standing controversy on the existence of hexagonal diamond,” researchers said.

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

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 brief: Chinese researchers have developed a synthetic diamond that is significantly harder and more resilient than those that occur naturally here on Earth. If commercially viable, the new diamond ...

Scientists from China have claimed they might have found a mineral that is harder than the cubic diamond, which is known to the world as the hardest existing mineral. The hexagonal diamond (HD) is ...

After decades of debates over the existence and properties of one of the world’s ...
