Nature's strongest material now has some stiff competition. For the first time, researchers have hard evidence that human-made hexagonal diamonds are stiffer than the common cubic diamonds found in ...

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 ...

Diamonds may be the strongest known natural material, but researchers have just created some stiff competition. By firing a dime-sized graphite disk at a wall at 15,000 mph (24,100 km/h), scientists ...

A team of physicists, materials scientists and engineers affiliated with several institutions in China, working with a colleague from Umeå University, in Sweden, has grown a diamond that is harder ...

For the first time, researchers have hard evidence that human-made hexagonal diamonds are stiffer than cubic diamonds found in nature and often used in jewelry. Hexagonal diamonds have been found at ...
