Nanocrystalline diamonds used to study materials under extreme conditions

07-Feb-2018

Using a nanocrystalline diamond built by plasma vapor deposition, Yogesh Vohra, Ph.D., has already produced a pressure nearly two times greater than that found at the center of the Earth. Now he reports that the manufacturing process of these novel, nanocrystalline-diamond micro-anvils has proved ...
