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 ...

The graphite found in your favorite pencil could have instead been the diamond your mother always wears. What made the difference? Researchers are finding out. How molten carbon crystallizes into ...

A Chinese research team has produced bulk hexagonal diamond, a crystal structure long theorized to be harder than conventional cubic diamond, from compressed graphite. The work, led by Sun Jian at ...

Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder. Evidence of this was gathered over the past sixty years in meteorite ...

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 ...

After decades of debate, researchers say that they have found the clearest evidence yet for this rare form of carbon. Diamond is famously known as the hardest mineral on Earth. But researchers have ...
