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

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 ...

Zinc sulphide exists with two different crystal structures, the cubic zinc blend (top diagram) and the hexagonal Wurtzite (lower diagram). In the zinc blend structure the sulphur ions form an fcc ...

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 ...

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 ...

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