The Meissner influence demonstrated by levitating a magnet over a cuprate superconductor, which can be cooled by liquid nitrogen Below some conditions, such as exceptionally very low temperatures, some ceramics exhibit high-temperature superconductivity (in superconductivity, "high temperature" indicates above thirty K). The explanation for this is not recognized, but there https://isolation-of-viral-rna04881.wikissl.com/2001944/top_guidelines_of_ceramic_coating_process
