High-temperature Superconductivity

High-temperature superconductivity is a technology that facilitates the use of ceramic materials for conducting and transmitting electricity with little or no resistance loss without the need to achieve low-temperature superconductivity. Despite its name, high-temperature superconductivity still occurs at cryogenic temperatures. The main difference from low-temperature superconductivity, which is usually achieved at or near the absolute zero temperature (minus 273 degrees Celsius), is that high-temperature superconductors (HTSs) can use liquid nitrogen (at minus 196 degrees Celsius) as a coolant.
