Making nanodiamonds out of bottle plastic

In the experiment, a thin sheet of simple PET plastic was shot at with a laser. The strong laser flashes that hit the foil-like material sample briefly heated it up to 6000 degrees Celsius and thus generated a shock wave that compressed the matter to millions of times the atmospheric pressure for a few nanoseconds. The scientists were able to determine that tiny diamonds, so-called nanodiamonds, formed under the extreme pressure. Credit: HZDR / Blaurock
