Superconduction News

Superconductivity is a phenomenon where certain materials can conduct electricity without resistance when they are cooled below a critical temperature. This temperature varies significantly among materials, from close to absolute zero (-273.15°C) up to higher temperatures for some newer compounds. When in the superconducting state, these materials also exhibit perfect diamagnetism, meaning they can expel a magnetic field, a property known as the Meissner effect. Discovered in 1911 by Dutch physicist Heike Kamerlingh Onnes, the phenomenon has since had significant implications in various fields, particularly in the development of technologies such as MRI machines, maglev trains, and particle accelerators. Theoretical understanding of superconductivity was advanced by the BCS theory in 1957, explaining it at a microscopic level using quantum mechanics for conventional superconductors. Ongoing research aims to develop materials that achieve superconductivity at room temperature, which would revolutionize energy transmission and storage.
