Researchers Find New, Easy Way To Turn Graphite Into Diamond

Since graphite — the dark material used in regular old pencils — and diamonds are both made from carbon, it’s technically feasible to turn the former into the latter. You just need to apply a little pressure — about 150,000 times what the atmosphere on Earth’s surface is like. But researchers at Stanford University claim to have found a shortcut.


How To Tell Real Diamonds From Fake

New Material Could Cool Gadgets Even Better Than Diamonds Do (Wait, What?)

As electronic devices get increasingly tiny, heat management becomes a bigger and bigger problem. In gadgets that can’t practically house a fan, heat sinks do the job of keeping sensitive electronics cool. So far, the best-performing heat transfer material has been diamond, which any rap video will remind you is crazy expensive.
