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

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 ...

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 ...

Through the simulations, the team also revealed the molecular structures of liquid carbon as it crystallized into graphite and then, separately, as liquid carbon crystallized into diamond.

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 stands up to a squeeze. Surprisingly, the material’s structure persists even when compressed to 2 trillion pascals, more than five times the pressure in Earth’s core, scientists report ...

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.
