"Debate Heats Up Over Validity of Near-Room-Temperature Superconductor Claims"
A team of Chinese researchers has reported potential signs of room-temperature superconductivity in copper-substituted lead apatite (CSLA), replicating previous experiments with some success. While the study, published on the pre-print server ArXiv, shows behaviors typical of superconductors, such as diamagnetic dc magnetization and hysteresis loops below 250 K, it lacks conclusive evidence of the Meissner effect, a key characteristic of superconductivity. The findings are preliminary and require further investigation and peer review, highlighting the ongoing challenges in achieving and confirming room-temperature superconductivity.
