Update: The authors have published a retraction of the paper described in this article. A new addition to the carbon family, pentadiamond, is predicted to be light like graphite, hard like diamond and ...

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 ...

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 ...

Diamond, one of the hardest known materials, could have a rival. A new form of carbon that is just as hard as the gemstone but as light as pencil graphite could theoretically be used for applications ...
