Most natural diamonds have ages between 1 billion and 3.5 billion years. Diamond is the only gem with a single element. Do ...

Diamond stands up to a squeeze. Surprisingly, the material’s structure persists even when compressed to 2 trillion pascals, more than five times the pressure in Earth’s core, scientists report January ...

As much mystique as they've been given by companies with vested interest, diamonds are little more than lumps of carbon. In science applications, diamond is useful as a tough protective coating and ...

BUFFALO, N.Y. — Superhard materials can slice, drill and polish other objects. They also hold potential for creating scratch-resistant coatings that could help keep expensive equipment safe from ...

Researchers have constructed microscopic carbon structures that boast the best combination of strength and elasticity of any material studied to date (Nat. Nanotechnol. 2019, DOI: ...

A new form of diamond has been created. Its unique structure gives it properties that are similar to those of natural diamonds, but it is more stable under extreme heat, so may be useful in tools that ...

Superhard materials can slice, drill and polish other objects. Now, science is opening the door to the development of new materials with these seductive qualities. Researchers have used computational ...
