Scientists created hexagonal diamond harder than regular diamond by squeezing and heating graphite under extreme conditions.

Natural diamond, seen here, has a cubic packing structure. But a much rarer form of diamond has hexagonal packing and has now ...

Two new carbon allotropes (H-carbon and S-carbon) are proposed, as possible candidates for the intermediate superhard phases between graphite and diamond obtained in the process of cold compressing ...

The brilliantly shiny diamond is more than just pretty; it's one of the hardest minerals on Earth, with a name derived from ...

Research Update: Direct conversion of amorphous carbon into diamond at ambient pressures and temperatures in air. APL Materials, 2015; 3 (10): 100702 DOI: 10.1063/1.4932622 ...

New surprises Carbon materials are continually surprising us – and the emphasis of research has been to find or cook things in between its natural forms of diamond and graphite. This new form is ...

Graphite squeezed between two diamond jaws at pressures of 170,000 atmospheres managed to produce a crack in the diamond. A team modelled various crystal structures that could result when graphite is ...

Converting graphite into diamond has been a long held dream of alchemists the world over. In the modern era, materials scientists have puzzled over this process because it’s hard to work out why ...

Graphite and diamond are the most familiar, while more exotic allotropes include graphene, with versatile electrical properties, and M-carbon and Bct-carbon, which rival diamond’s legendary ...

The popular idea of carbon is that it comes in two forms. Either it's an opaque, black substance like coal, or a hard, brilliant crystal like diamond.
