Iron can form compounds with helium at pressures as low as 5GPa – about 50,000 atmospheres – researchers in Japan report.

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 ...

A new carbon-based material, monolayer amorphous carbon (MAC), is revolutionizing materials science. Unlike graphene, which ...

because while diamond forms with a tetrahedral arrangement in its carbon lattice (known as diamond cubic), lonsdaleite forms a hexagonal one that increases thermal stability and hardness.
