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

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

The hexagonal wurtzite structure has the sulphur ions in an hcp array and one-half of the tetrahedral sites in this structure are occupied by zinc ions. The crystal has a basal lattice parameter, a = ...

Hexagonal close packing is one of two crystal structures that derive from stacking close-packed-planes of hard sphere atoms. In the HCP structure only two stacking ...

Lonsdaleite, for example, is a type of diamond that was first discovered in 1967 in the Canyon Diablo meteorite and boasts a hexagonal lattice structure. The lab-grown diamond in question is of ...

Researchers have previously pursued harder diamonds with hexagonal rather than cubic lattices ... However, past attempts to make hexagon-lattice synthetic diamonds have resulted in diamonds ...

A team from Jilin University and Sun Yat-sen University say their lab-grown version is at least 40 per cent harder and far ...
