Earlier this year, amorphous diamond was synthesized for the first time using a technique involving high pressures, moderately high temperatures and a tiny amount of glassy carbon as starting material ...

Scientists create first-of-its-kind ‘hexagonal diamond’ harder than real thing - Material exhibits slightly higher hardness than naturally found diamond ...

Diamond is a famously hard material, but now scientists at City University of Hong Kong have managed to stretch it further than ever before. Why? Stretching nanoscale samples changes their electronic ...

To synthesize the crystals, the team compressed highly ordered pyrolytic graphite to pressures as high as 20 gigapascals, ...

Diamond composites have emerged as critical materials in cutting, drilling and other high-performance applications due to their exceptional hardness and wear resistance. Recent work has focused on ...

Long known as the hardest of all natural materials, diamonds are also exceptional thermal conductors and electrical insulators. Now, researchers have discovered a way to tweak tiny needles of diamond ...
