Even with the weight of worlds on its shoulders, diamond resolutely refuses to buckle under the pressure. Thanks to the highest-pressure X-ray diffraction experiments ever reported, researchers have ...

WASHINGTON, D.C., September 8, 2015 -- Diamonds are forever, except when they oxidize while cutting through iron, cobalt, nickel, chromium, or vanadium at high temperatures. Conversely, cubic boron ...

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 ...

In nature, diamonds form deep in the Earth over billions of years. This process requires environments with exceptionally high pressure and temperatures exceeding 1,000°C. Our international team has ...
