I think hope is that structures formed at such high pressures would be quasi-stable at atmospheric pressure. Such behavior is no unheard of.
Such pressures is not something our materials can handle on macro scopes. Yet.
But they are naturally occurring outside diamond anvils, like deep I gas giants, etc.
It’s facing that such super high pressure chemistry may be more common than our low pressure one, because of the abandonment of raw materials in big planets.
- DoctorOetker 7y agowhile what you describe is imaginable, I don't think this is the case, as physicists would then speak of "superconductivity at temperature T for a material in phase X formed at pressure P", not "[ ... ] superconductivity at megabar" Perhaps you also think the claim states room temperature conductivity, and one only needs 260K temperature to form this phase? When the title is phrased like it is, it usually describes a point or region for the equation of state
- elcritch 7y agoGood point on the state. One good thing from such research results even if impractical itself can yield good targets for future research. If it’s a matter of geometry or crystal lattice spacing from the pressure an alternate formulation might be able to make a meta-stable structure that induces superconductance. Perhaps there’s another part of the state diagram that could be modified.
- Svoka 7y agoIndeed. It is important to pursue research even if there is no immediate benefit from it. In this case it is even touching on a gateway technology I would call marvellous. Stable high temperature superconductor material would change so much.
