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 ...

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 the ...

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 ...

Discuss the implication of growing diamonds: In the NOVA scienceNOW video segment, Neil visits a "diamond farm"—a secret location where the diamonds are "chemically, physically, and optically ...

A team of researchers has for the first time observed and recorded the creation of hexagonal diamond under shock compression, revealing crucial details about how it is formed. The discovery could help ...

Subsequent research proved the graphite had turned into diamond. The Purdue researchers have named the process confined pulse laser deposition (CPLD). The research team confirmed that the structures ...

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 little ...

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

Molten carbon can crystallize into diamond or graphite, but it has been difficult to study this process. New simulations show that graphite can sometimes "hijack" the pathway that would lead to ...

This illustration depicts a new technique that uses a pulsing laser to create synthetic nanodiamond films and patterns from graphite, with potential applications from biosensors to computer chips.
