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 ...

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 ...

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 ...

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 ...
