Molten carbon can form into either diamond or graphite. A new study shows how graphite can sometimes form even under conditions that should lead to diamond. (Getty Images) The graphite found in your ...

Diamonds are famous for their strength, but scientists have long suspected that another form of diamond might be even harder.

Converting graphite into diamond has been a long held dream of alchemists the world over. In the modern era, materials scientists have puzzled over this process because it’s hard to work out why the ...

The diamond was around 0.04 inches in size and exhibited more sturdiness and resistance compared to typical cubic diamonds.

This illustration depicts a new technique that uses a pulsing laser to create synthetic nanodiamond films and patterns from graphite, with potential applications from biosensors to computer chips.

Scientists have for the first time turned diamond into graphite using ultra-short flashes of an X-ray laser. (Image: Reuters) Scientists have for the first time turned diamond into graphite using ...
