Unexpected new material has been quenched to ambient pressure
(PHYSorg.com Chemistry)

Scientists from the National University of Science and Technology MISIS together with colleagues from Germany and Sweden achieved a result that seemed impossible. The researchers managed to create at ultra-high pressures a new material that preserves its structure and properties even under normal atmospheric pressure. Moreover, it turned out that it can be recreated in more `trivial` laboratory conditions via complex chemical reactions. The results of the experiment alongside with their theoretical explanation are presented in Nature Communications.
