Room temperature & pressure superconductor

Still need to wait for replication, but if this turns out to be real could be pretty awesome:

For the first time in the world, we succeeded in synthesizing the room-temperature superconductor (Tc≥400 K, 127∘C) working at ambient pressure with a modified lead-apatite (LK-99) structure. The superconductivity of LK-99 is proved with the Critical temperature (Tc), Zero-resistivity, Critical current (Ic), Critical magnetic field (Hc), and the Meissner effect. The superconductivity of LK-99 originates from minute structural distortion by a slight volume shrinkage (0.48 %), not by external factors such as temperature and pressure.

127C seems a little hot for "room temperature", though, but I'm not sure how necessary that high temperature is. Seems a little odd given that superconductors usually require extremely low temperatures.

Anyway, this is just an arxiv paper right now, hasn't even been through peer review let alone having been replicated, but seems like this space may be worth watching. :)
