Figure 1: Schematic phase diagram of SI ice from 50 GPa to 2.5 TPa. At 2,200 K, we find a reversible transition from the BCC-SI phase to a SI phase with the close-packed oxygen sublattice at ...

Caption 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 ...

The work has been published in Nature. Plastic ice VII was originally predicted more than 15 years ago by molecular dynamics (MD) simulations as a phase of water that could exist under high ...

Physicists with the U.S. Department of Energy have discovered a new phase of matter—and, with apologies to George R. R. Martin, it's something of "a song of ice and fire." The duo from the ...

A strange type of ice thought to dwell deep in the oceans of alien planets has finally been proven to exist. For the first time, researchers have directly observed a sort of hybrid phase of water ...
