A Chinese research team has produced bulk hexagonal diamond, a crystal structure long theorized to be harder than ...
A research team led by Sun Jian at Nanjing University has produced recoverable, millimeter-sized crystals of hexagonal diamond, a rare carbon polymorph that prior theoretical work has suggested could ...
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 ...
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 ...
