A Chinese research team has produced bulk hexagonal diamond, a crystal structure long theorized to be harder than ...

Molten carbon can form into either diamond or graphite. A new study shows how graphite can sometimes form even under conditions that should lead to diamond. (Getty Images) The graphite found in your ...

Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder.

Carbon forms the graphite in pencils, the diamonds in jewelry and the molecules that make up every living thing. But under extreme conditions—like the heat and pressure of intense explosions—carbon ...

The new method can determine crystal structures underlying experimental data thus far difficult to analyze. A joint research team led by Yuuki Kubo and Shiji Tsuneyuki of the University of Tokyo has ...

Scientists found something unexpected inside a meteorite that hit Earth 50,000 years ago. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. While ...

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 ...

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 ...
