Physicists have successfully created a lab-grown diamond with a hardness exceeding that of natural diamonds. By subjecting ...

Diamond is well-known for being the hardest natural material on Earth, though synthetic forms have been developed that are ...

The majority of naturally appearing graphite has hexagonal stacking, making it one of the most “ordinary” materials on Earth. The structure of graphite crystal is a repetitive pattern. This pattern ...

Led by Liu Bingbing and Yao Mingguang from Jilin University, the researchers discovered that by heating highly compressed graphite, it can transform into a hexagonal diamond. This synthetic ...

The lab-grown diamond in question is of the hexagonal variety, and was created by heating highly compressed graphite. Using this approach, the team made a millimeter-sized hexagonal diamond that ...

Zipline Ski, a leader in high-performance ski equipment, is redefining the standards of ski pole innovation with the launch of its Hexagon Triax W ...

Charcoal and graphite are also allotropes of carbon ... its carbon lattice (known as diamond cubic), lonsdaleite forms a hexagonal one that increases thermal stability and hardness.
