Graphite and diamond have similar free energies but converting one into the other is famously hard. Now materials scientists think they know why ...

The graphite found in your favorite pencil could have instead been the diamond your mother always wears. What made the difference? Researchers are finding out.How molten carbon crystallizes into ...

A Yale-led team of mineral physicists has for the first time confirmed through high-pressure experiments the structure of cold-compressed graphite, a form of carbon that is comparable in hardness to ...

This three-dimensional structure accounts for the physical properties of graphite. Unlike diamond, graphite can be used as a lubricant or in pencils because the layers cleave readily.

Scientists have for the first time turned diamond into graphite using ultra-short flashes of an X-ray laser.

Exposing this layered structure to an ultrafast-pulsing laser instantly converts the graphite to an ionized plasma and creates a downward pressure. Then the graphite plasma quickly solidifies into ...

Since graphite—the dark material used in regular old pencils—and diamonds are both made from carbon, it’s technically feasible to turn the former into the latter. You just need to apply a ...

Researchers have succeeded in creating a rare type of diamond, known as lonsdaleite or hexagonal diamond. This material, ...

Meteorite diamonds, which could be 58% harder than ordinary diamonds, have finally been made in the lab. Scientists have ...

Diamond and graphite are different forms of carbon thatdiffer in their inner crystal structure. Diamond is thehigh-pressure phase that forms deep in the earth.

Washington, Dec 11 (PTI) Scientists have for the first time turned diamond into graphite using ultra-short flashes of an X-ray laser.
