Where would carbon-based life be without carbon? There are 118 known chemical elements, but carbon is the fourth most abundant and perhaps the most important to human life. Everywhere you look, ...

As a crystalline material composed of amorphous clusters, OACC is the first hybridized carbon structure ever seen that is part amorphous and part crystalline. Collapsing carbon cages To make the new ...

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.

Unlike crystalline forms of carbon such as diamonds, whose hardness is highly dependent upon the direction in which the crystal is formed, ...

Carbon is the fourth-most-abundant element in the universe and takes on a wide variety of forms, called allotropes, including diamond and graphite. Scientists have now discovered a new form of ...

Graphyne is a crystalline form of carbon that is distinct from both diamond and graphite. Unlike diamond, where each atom possesses four immediate neighbors, or graphite, where each atom has three ...

The carbon atoms in a diamond form "3-D" bonds with their neighbors, resulting in a sturdy, pyramidlike, repeating crystalline structure. (Related: "'Diamond' Planet Found; May Be Stripped Star." ...

Canadians may think they're intimately familiar with ice in all its forms, but there is one kind that most have probably ...

This new carbon form was capable of withstanding 1.3 million times normal atmospheric pressure in one direction while confined under a pressure of 600,000 times atmospheric levels in other directions.

The ideal crystalline structure of graphene is a hexagonal grid. (Photo credit: Wikipedia) Graphene is a crystalline form of carbon in which carbon atoms are arranged in a regular hexagonal pattern.
