The Meissner result demonstrated by levitating a magnet above a cuprate superconductor, which is cooled by liquid nitrogen Less than some disorders, for instance particularly lower temperatures, some ceramics exhibit high-temperature superconductivity (in superconductivity, "high temperature" means higher than thirty K). The main reason for this is not recognized, but https://andyrtrqp.blogdomago.com/37837290/top-latest-five-ceramic-alumina-urban-news
