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 ...

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 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.

This invention relates to methods of making new and improved diamond, "diamond-like carbon" (a-C) and "diamond-like hydrocarbon" (a-C:H) coatings bonded to substrates by using intermediate bonding ...

A perspective cartoon drawing of nanostructured diamond capsules (NDCs) with high-pressure argon nanodomains embedded in the matrix. Modern diagnostic probes such as hard/soft x-ray, ultraviolet ...
