Worldwide scientific collaboration finds LK-99 is not a room-temperature superconductor [TechSpot]

Then in 1986, scientists discovered a class of copper oxide that displayed the same drop in resistance but at a higher temperature – about 77.2 K (-196°C). These materials became known as “high-temperature” superconductors, although they still had to be chilled way below freezing. This discovery sparked a race to…Read Entire Article
