“They were very precise about it: 104.8 ºC,” says Prashant Jain, a chemist at the University of Illinois at Urbana–Champaign. “I was like, wait a minute, I know this temperature.”
Jain, a copper-sulfide specialist, remembered 104 ºC as the temperature at which Cu2S undergoes a phase transition. Below that temperature, the resistivity of air-exposed Cu2S drops dramatically — a signal almost identical to LK-99’s purported superconducting phase transition. “I was almost in disbelief that they missed it,” says Jain, who published a preprint7 on the important confounding effect.
