Room Temperature Superconductivity

Facts for Prelims (FFP)   Source: TH  Context: A recent study by scientists in China and Japan has reported signs of superconductivity in a material called LK-99, which had been controversially claimed to be a room-temperature and pressure (RTP) superconductor.   The researchers observed the Meissner effect in copper-substituted lead apatite, indicating superconductivity. The Meissner …
