The Meissner influence demonstrated by levitating a magnet over a cuprate superconductor, which can be cooled by liquid nitrogen Underneath some conditions, for example really minimal temperatures, some ceramics exhibit high-temperature superconductivity (in superconductivity, "high temperature" implies over thirty K). The key reason why for this is not comprehended, but https://isolationofviralrna93692.blogpostie.com/60351568/an-unbiased-view-of-aluminiumoxide
