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 ...

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 ...

(PhysOrg.com) -- Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a ...

Researchers have succeeded in creating a rare type of diamond, known as lonsdaleite or hexagonal diamond. This material, whose hardness could surpass that of conventional diamonds, opens new ...

Add Yahoo as a preferred source to see more of our stories on Google. A rare form of diamond from outerspace is held in the tiny meteorite held by Monash University Professor Andrew Tomkins and Royal ...

Australian scientists have discovered strangely folded diamonds in rare meteorite samples. In investigating how they came to form, the team found evidence that they were forged in a cataclysm on an ...

Scientists have discovered a mineral stronger than a diamond called lonsdaleite. The mineral, which has been theorized about for years, was recently found in Africa after meteorites landed in the ...

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 ...

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 ...

While traditional diamonds are formed over billions of years deep in the Earth where extreme pressures and temperatures provide just the right conditions to crystalize carbon, scientists are working ...
