Watch this video to understand the different properties of diamond and graphite. The rigid network of carbon atoms, held together by strong covalent bonds, makes diamond very hard. This makes it ...

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 ...

The graphite-diamond phase transition is of particular interest for fundamental reasons and a wide range of applications. In new experiments, Lawrence Livermore National Laboratory (LLNL) scientists ...

An international research team has produced a bulk, millimeter-scale hexagonal diamond in the laboratory, a crystal variant long theorized to rival or exceed the hardness of the cubic diamonds found ...

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 ...
