Unfortunately the pressure in HPP machines is dispersed over a large vessel (foot scale diameter cylinders), while diamond anvil cells and the like focus that pressure at the mm/sub-mm scale.
Would be nice though!
- bufferoverflow 7y agoWhy would that matter? High pressure is high pressure. Large vessel would mean you can grow many diamonds at the same time, no?
- mogadsheu 7y agoYou might be right... pressure needed for diamond synthesis is almost certainly much higher than for killing bacteria via pressure drop. Turns out, it is, and they add temperature to the mix: >They were able to heat carbon to about 3,000 °C (5,430 °F) under a pressure of 3.5 gigapascals (510,000 psi) for a few seconds.
