Phase diagram. We use constant-pressure (NPT) ab-initio molecular dynamics (AIMD) 22 to systematically investigate the SI phase diagram of heavy ice (D 2 O) from 200 GPa to 2.5 TPa.In the ...

The phase-change devices presented in this research are already pretty small—squares that are about 100 nanometres across. What IBM's multi-artificial-neuron computer looks like. Credit: IBM ...
