Traction motors operate on the same basic principles as standard AC or DC electric motors, which are among the most common types used in industrial and consumer applications. Electrical charge is ...
Copper-oxide (CuO2) superconductors, such as Bi2Sr2CaCu2O8+ (Bi2212), have unusually high critical temperatures. Optical reflectivity measurements of Bi2212 have shown that it exhibits strong optical ...
