Sporcle Settings to finish the process.
Some tend to break when produced, others lose their superconductivity within minutes or hours.

He found the electrical resistivity of a mercury wire to disappear suddenly when cooled below a temperature of 4 Kelvin (-269 C).
The Bardeen-Cooper-Schrieffer theory) are sufficient, or whether new concepts will be needed.
Prestige, economic and military benefits could well come to the nation that first will master this new field of physics.The new idea was that the copper atoms in a material of this kind could be made to transport electrons, which interact more strongly with the surrounding crystal than they do in normal electrical conductors.Pilot systems have also been developed for other applications such as electrical generators and energy storage arrangements.Superconductivity enables electrical currents to flow through a wire or other conductor with little of the resistance that ordinarily would sap the current's strength and produce heat.Bednorz and Müllers new approach was to abandon the conventional semiconducting alloys, for instance of niobium-germanium or niobium-tin type, and to direct their search among metal oxides.Magnetic fields can be used to measure the tiny current of electricity in the human brain, enabling scientists literally to create a map of the thought process.But there's a practical problem.Moreover, scientists lack a full understanding of how ceramics become superconductors.Onnes, who was awarded the Nobel Prize in 1913 for his low-temperature research.
