The Meissner influence demonstrated by levitating a magnet previously mentioned a cuprate superconductor, that is cooled by liquid nitrogen Underneath some problems, which include particularly lower temperatures, some ceramics exhibit high-temperature superconductivity (in superconductivity, "high temperature" means higher than 30 K). The main reason for this is not comprehended, but https://reagents-used-in-dna-extr61470.tdlwiki.com/2034331/ceramicos_propiedades_for_dummies
