A new form of carbon that rivals diamonds in its hardness, but has an amorphous structure similar to glass, has been produced under ultrahigh pressure in laboratory experiments.

An amorphous diamond – one that lacks the crystalline structure of diamond, but is every bit as hard – has been created by a Stanford-led team of researchers. But what good is an amorphous ...

A team of Stanford earth science researchers has pioneered the “amorphous diamond,” a new carbon material as hard as diamond but lacking its crystalline structure.

Earlier this year, amorphous diamond was synthesized for the first time using a technique involving high pressures, moderately high temperatures and a tiny amount of glassy carbon as starting ...

Chris Walker looks at some of the uses of a novel amorphous diamond material. Diamond — hard, sparkling and bright — has been revered for thousands of years as a gemstone. Nowadays it is also widely ...

The key to the technology is the amorphous diamond emitter, which is what Thomas calls an electromagnetic cathode coated with amorphous diamond. Amorphous diamond lacks hydrogen, which makes it harder ...

The team's comprehensive mechanical testing proved AM-III to be the hardest and strongest amorphous material known so far, and capable of scratching the surface of a diamond.

Historical Archive Sandia diamond coatings extending material life 17 Jun 2002 Scientists at Sandia National Laboratories have developed a method to relieve the internal stresses of amorphous, or ...

The scientists found Q-carbon to be 60% harder than diamond-like carbon (a type of amorphous carbon with similar properties to diamond).

Researchers from the University of Tokyo, in collaboration with NTT Basic Research Laboratories have discovered that an ‘amorphous diamond’ structure would make a perfect photonic crystal.

The coal ions penetrate the surface and bond to form an amorphous, diamond-like coating less than 100 nanometres thick.
