The Meissner outcome demonstrated by levitating a magnet previously mentioned a cuprate superconductor, that is cooled by liquid nitrogen Underneath some circumstances, for instance extremely lower temperatures, some ceramics show high-temperature superconductivity (in superconductivity, "high temperature" indicates previously mentioned thirty K). The reason for this is not understood... https://andersonxisbk.oblogation.com/38107666/nitreto-de-boro-hexagonal-an-overview
