superconductivity
A scientist demonstrates superconductivity by levitating a magnet above a cooled material.
Noun: * The property of zero electrical resistance in certain materials when cooled below a critical temperature: Superconductivity is a quantum mechanical phenomenon where a material can conduct electric current with no energy loss due to resistance.
Superconductivity is a scientific term used primarily in physics, materials science, and engineering. It describes the state of a superconductor. * The discovery of superconductivity revolutionized our understanding of condensed matter physics. * Practical applications of superconductivity include MRI machines and maglev trains.
- "High-temperature superconductivity": Refers to materials that exhibit superconductivity at temperatures above the boiling point of liquid nitrogen (77 K or -196 °C), which is considered high relative to earlier superconductors that required cooling with liquid helium.
- Research into high-temperature superconductivity aims to find materials that work at room temperature.
- Superconductor (noun): A material that exhibits superconductivity.
- Niobium-tin is a common superconductor used in magnets.
- Superconducting (adjective): Having the properties of a superconductor.
- The superconducting wire carries the current without any loss.
- Zero-resistance conduction (descriptive phrase)
This word has a single, specific technical meaning in physics. It does not have common idiomatic or figurative uses.
