Scientists have discovered that an ancient "catastrophic collision" between a dwarf planet and an asteroid is responsible for the creation of a rare and mysterious cosmic gem. The findings, published ...

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 ...

First identified in 1967, lonsdaleite is the hardest naturally-occuring mineral ever discovered—yes, it’s even harder than diamonds. Lonsdaleite, however, has only been found in meteorites, suggesting ...

Pop quiz: what is the world’s hardest material? Answer: it’s diamond, of course. Thanks to the crystal structure of diamonds, with carbon atoms arranged into a lattice-like structure, diamond is top ...

New research indicates that a rare form of diamond may originate in the burbling cores of distant worlds, arriving on Earth thanks to violent cosmic collisions. According to a team of scientists in ...

In the case of lonsdaleite [hexagonla diamond], compression mechanism also caused bond-flipping, yielding an indentation strength of 152 GPa, which is 58 percent higher than the corresponding value of ...

A study on the diamonds titled "Sequential Lonsdaleite to Diamond Formation in Ureilite Meteorites via Chemical Fluid/Vapor Deposition" has been published in the journal Proceedings of the National ...

The formation of diamond after applying pressure and heat on graphite is highly relevant to the artificial synthesis of diamond 1,2,3,4, and also for a general understanding of high pressure phase ...
