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 ...

Hexagonal boron nitride has a layered crystalline structure in a hexagonal lattice arrangement composed of alternating boron and nitrogen atoms held together by strong covalent bonds. This structure ...

For the first time, researchers have hard evidence that human-made hexagonal diamonds are stiffer than cubic diamonds found in nature and often used in jewelry. Hexagonal diamonds have been found at ...

Scientists have used a mix of physical and chemical properties to bend salt into hexagonal crystals for the first time ever. They formed the thin layer of crystalline salt on a substrate (foundation ...

Currently, diamond is regarded to be one of the hardest and most scratch-resistant natural materials in the world. Most diamonds found in nature and often used in jewelry display a cubic crystal ...
