At high pressure, water forms superionic ice with an oxygen lattice and melted liquid hydrogens, which could exist on ice-rich planets. Here, Sun et al. predict a new phase of superionic ice where ...

The phase diagram shows the state of water (H2O) under very high pressure (X-axis) and temperature conditions (Y-axis). These conditions apply in the interior of the ice planets Uranus and Neptune ...

An international team co-led by Ho-Kwang Mao and Huiyang Gou from Center for High Pressure Science and Technology Advanced Research (HPSTAR) and Yansun Yao from University of Saskatchewan discovered ...

They explored a large pressure range from 1.2 to 1.9 million times normal atmospheric pressure, and saw the formation of a new nitrogen phase at approximately 1.5 million times normal atmospheric ...
