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 ...

Diamond has long been regarded as the practical and theoretical hardness champion and has found uses ranging from industrial abrasives to a girl's best friend. Cubic boron nitride, a synthetic ...

DIAMOND is generally thought to be one of the most perfect crystals occurring naturally: its atomic structure was first investigated in the very early days of X-ray crystal analysis. It turned out ...

Researchers combine diamond and cubic boron nitride with a novel alloying process for a superhard material. Diamonds are forever, except when they oxidize while cutting through iron, cobalt, nickel, ...

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 ...
