SUPERCONDUCTIVITY 297K! SYNTHETIC HIGHWAYS TO ROOM TEMPERATURE SUPERCONDUCTIVITY ALMADEN INSTITUTE 2012 Piers Coleman Center for Materials Theory, Dept of Physics and Astronomy, Rutgers
Superconductivity is the phenomenon in nature where the electrical resistance of a conducting sample vanishes completely below a certain temperature which is known as “critical temperature (Tc)”.
The phenomenon of superconductivity, in which the electrical resistance of certain materials completely vanishes at low temperatures, is one of the most interesting and sophisticated in condensed matter physics. It was first discovered by the Dutch physicist Heike Kamerlingh Onnes, who was the first to liquefy helium (which boils at 4.2 Kelvin at standard pressure). In 1911 Kamerlingh Onnes

The phenomenon of superconductivity was discovered by Kamerlingh Onnes in 1911, in metallic mercury below 4 K (−269.15 °C). Ever since, researchers have attempted to observe superconductivity at increasing temperatures with the goal of finding a room-temperature superconductor. By the late 1970s, superconductivity was observed in several

However, if we’re able to harness the powers of superconductivity at room temperature, we could transform how energy is produced, stored, distributed and used around the globe.
Superconductivity is related to normal conductivity to the extent that in general, good conductors at room temperature are either non-superconductors or poor superconductors. 3) Magnetic materials are not superconductors; Magnetism and superconductivity appear to be mutually exclusive.
