    Below 110K. Still on the right track but not proof of room temp superconductor yet.

      110K (-163C, -262F) is still a significant improvement in cryo temperatures required for superconductivity. It no longer requires liquid helium temperatures for things like MRI magnets. So even if this is not a “holy grail” room temperature SC- it still enables the use of much cheaper commodity cryogenics like liquid nitrogen for use in scientific and industrial superconductors.

        It still loses to HgBa2Ca2Cu3O8+6 with Tc = 133–138 K at normal air pressure, though. (I assume it’s normal air presure as the article doesn’t say the pressure for it, while it refers to some others as high-pressure ones.)

        Maybe LK-99 still has other benefits, such as not using mercury.

      honestly i’d be happy with a LN2 superconductor that works for MRI.

        Isn’t rebco tape already a decent candidate for that, and much further along in development pipelines?

      The more independent tests come out the less it’s looking like this is a superconductor. There might still be something interesting going on here, but I’m becoming skeptical of the original claims myself.

        Well, at least not at room temperature. But it still seems like it might be an incremental upgrade to what we have today.

    lets-fucking-go

    -163C is still pretty cold, but at least it is superconducting
