Diamond is among the hardest naturally occurring substances on Earth, but if you shrink it down to the nanoscale, it is surprisingly elastic. And that could be useful for a host of applications such as quantum computing. In a paper published in the journal Physical Review X, Chongxin Shan at Zhengzh ou University in China and colleagues studied diamonds as small as four nanometers across to see how they respond to pressure. ...read more read less
