Over time, researchers have consistently encountered superconductivity at temperatures previously considered unexpected or impossible, challenging the notion that achieving superconductivity at room temperature was infeasible. [4] [5] The concept of "near-room temperature" transient effects has been a subject of discussion since the early 1950s.
The table below shows some of the parameters of common superconductors. X:Y means material X doped with element Y, T C is the highest reported transition temperature in kelvins and H C is a critical magnetic field in tesla. "BCS" means whether or not the superconductivity is explained within the BCS theory.
Low-temperature superconductor (LTS) wires are made from superconductors with low critical temperature, such as Nb 3 Sn (niobium–tin) and NbTi (niobium–titanium). Often the superconductor is in filament form in a copper or aluminium matrix which carries the current should the superconductor quench for any reason.
High-temperature superconductors (HTS) become superconducting at more easily obtainable liquid nitrogen temperatures, which is much more economical than liquid helium that is typically used in low-temperature superconductors. HTS are ceramics, and are fragile relative to conventional metal alloy superconductors such as niobium-titanium.
Founded by researchers with this IBM program, HYPRES developed and commercialized superconductor integrated circuits from its commercial superconductor foundry in Elmsford, New York. [8] The Japanese Ministry of International Trade and Industry funded a superconducting research effort from 1981 to 1989 that produced the ETL-JC1 , which was a 4 ...
If a new superconductor works out, its 100% efficiency will make the worldwide grid even more of a no-brainer. Paul deLespinasse: Room temperature superconductors, the worldwide grid, solar energy ...
An organic superconductor is a synthetic organic compound that exhibits superconductivity at low temperatures. As of 2007 the highest achieved critical temperature for an organic superconductor at standard pressure is 33 K (−240 °C; −400 °F), observed in the alkali-doped fullerene RbCs 2 C 60 .
Breakthrough would mark ‘holy grails of modern physics, unlocking major new developments in energy, transportation, healthcare, and communications’ – but it is a long way from being proven
