The structure, an interlocking form of graphite and diamond, has unique properties that could one day be used to develop superfast charging or new types of electronics, researchers say.

Scientists have successfully synthesized lonsdaleite, a hexagonal diamond 40% harder than diamond, after 50 years of attempts ...

A diamond is a motley thing ... “We point out how it’s important to know exactly the underlying grain structure of crystal particles that are being studied. If you’re collecting the emission ...

Diamond and graphite are polymorphs of carbon, for example. Some molecules can crystallize in as many as a dozen or so different forms, Szalewicz said. “Investigations of crystal structures are an ...

diamond is regarded to be one of the hardest and most scratch-resistant natural materials in the world. Most diamonds found in nature and often used in jewelry display a cubic crystal structure, a ...

To this end, scientists at the Technical University of Denmark and Stanford University successfully filmed sound waves in a diamond crystal structure for the first time ever using an X-ray free ...
