Carbon forms the graphite in pencils, the diamonds in jewelry and the molecules that make up every living thing. But under ...

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

Researchers have synthesized millimetre-scale hexagonal diamond, a crystal structure so elusive that many physicists doubted ...

After decades of debate, researchers say that they have found the clearest evidence yet for this rare form of carbon ...

Tiny diamond particles can help fabric release heat—and despite being diamonds, they’re surprisingly affordable to make. On a hot day, most clothing traps heat. But fabric coated with ...

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

Carbon is everywhere. It forms the graphite in pencils, the diamonds in jewelry and the molecules that make up every living thing. Under extreme conditions -- like the heat and pressure of intense ...

Researchers made small, pure samples of the elusive mineral lonsdaleite – also known as hexagonal diamond — and tested its ...

Atomic structure of the hexagonal diamond. Image from the study. Researchers named it lonsdaleite, after crystallographer ...

Carbon comes in many different structures, most famously graphite and diamond. Other forms were predicted to exist at extremely high pressures, but now researchers have examined carbon under the ...
