The first room-temperature ambient-pressure superconductor?

https://arxiv.org/abs/2307.12008

Summary: Researchers have successfully synthesized the first room-temperature ambient-pressure superconductor, LK-99, with a critical temperature of 400 K (127°C). The superconductivity originates from minute structural distortion caused by Cu²⁺ substitution of Pb²⁺(2) ions, creating superconducting quantum wells. This breakthrough could have significant implications for energy efficiency and technology applications.
