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

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

The vast majority of polished diamonds are clear and sparkly, but some come in unexpected colors like blue, green and even ...

A £110M-per-gram carbon sphere may revolutionize GPS and smartphones. This nitrogen-filled fullerene powers atomic clocks ...

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

Chinese researchers have succeeded in synthesising the hundred-micron-scale hexagonal diamond, a material primarily found in meteorites, which is harder than the ordinary diamond found on Earth.

In fact, diamonds are being used in a revolutionary capacity. They are an essential part of a battery that may last for ...

Whatever it's been called - plumbago, black-cawke, wadd, black-lead - through century after century, graphite has been ...

A study conducted by researchers at the University of São Paulo (USP) in Brazil and the Università degli Studi di Roma "La Sapienza" in Italy has synthesized fullerenes and hollow spherical graphene ...

Diamond is the high-pressure allotrope of carbon, though less stable than graphite and lonsdaleite, the other two crystalline forms of carbon. It is the naturally hardest material known and thus ...

British researchers have developed diamond batteries that use carbon-14 to generate microwatts' worth of power for up to 5,700 years.
