Physicists have successfully created a lab-grown diamond with a hardness exceeding that of natural diamonds. By subjecting graphite to extreme pressure and heat, researchers synthesized a rare ...

the researchers discovered that by heating highly compressed graphite, it can transform into a hexagonal diamond. This synthetic creation possesses a hexagonal crystal form, which provides much ...

The most abundant form of graphite is flake graphite ... These metamorphic conditions produced rocks with crystals of graphite trapped inside them. On the other hand, amorphous graphite formed ...

The structure of graphite crystal is a repetitive pattern. This pattern gets disrupted at the surface of the crystal and leads to what's called 'surface states', which are like waves that slowly fade ...

Diamond is well-known for being the hardest natural material on Earth, though synthetic forms have been developed that are even tougher – a feat that researchers have managed again, through a new ...
