Researchers in China say they have produced hexagonal diamond, a long-disputed form of carbon that theory predicts could be ...

ANU Associate Professor Jodie Bradby said her team – including ANU PhD student Thomas Shiell and experts from RMIT, the University of Sydney and the United States – made nano-sized Lonsdaleite, which ...

The graphite-diamond phase transition is of particular interest for fundamental reasons and a wide range of applications. In new experiments, Lawrence Livermore National Laboratory (LLNL) scientists ...

Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder. Evidence of this was gathered over the past sixty years in meteorite ...

A mystery that puzzled scientists for more than half a century may finally have an answer. The strange crystals hidden in a famous Arizona meteorite have now been recreated in a lab, and they could ...

To synthesize the crystals, the team compressed highly ordered pyrolytic graphite to pressures as high as 20 gigapascals, roughly 200,000 times the atmospheric pressure at Earth’s surface. Chinese ...

A new study by Washington State University researchers answers longstanding questions about the formation of a rare type of diamond during major meteorite strikes. Hexagonal diamond or lonsdaleite is ...

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 ...
