Superconductivity at near room temperature!

The caveat is the sample was squished under 170 gigapascals of pressure, about 15 million PSI. Not exactly ready for prime time but it does show there are possibilities for further research, maybe get that down to a mere 100 Gigapascals😉

And the 250K figure mentioned in that link translates to -23.15C (although obviously they didn't measure it to that level of accuracy).

Here is a phys.org/news link to that;

It is a crack in the quest for room temps though. I wonder what happens if they reduce the pressure and then go back to 170?

Well the point is that you need the phase LaH10 which is only stable at extreme pressures. As soon as you release the pressure a hase transition takes place...

@Ponderable

Let's see. Coat the stuff with superglue?😉
