the phenomenon of almost perfect conductivity shown by certain substances at temperatures approaching absolute zero. The recent discovery of materials that are superconductive at temperatures hundreds of degrees above absolute zero raises the possibility of revolutionary developments in the production and transmission of electrical energy.

How to use superconductivity in a sentence
For the discovery to ever have practical applications though, the researchers will have to find a way to reduce the pressure required to achieve superconductivity.Scientists Just Achieved Room Temperature Superconductivity for the First Time | Edd Gent | October 19, 2020 | Singularity Hub
Over the next few decades superconductivity was found in other super-cooled materials, and in 1933 researchers discovered that superconductors also expel magnetic fields.Scientists Just Achieved Room Temperature Superconductivity for the First Time | Edd Gent | October 19, 2020 | Singularity Hub
Scientists have for decades sought to understand just what those circumstances are, and to figure out what other elements might be mixed in with hydrogen to achieve superconductivity at progressively higher temperatures and lower pressures.Room-temperature superconductivity has been achieved for the first time | Niall Firth | October 14, 2020 | MIT Technology Review
For many decades afterwards, superconductivity was created only at extremely low temperatures.Room-temperature superconductivity has been achieved for the first time | Niall Firth | October 14, 2020 | MIT Technology Review
That’s more than 50 degrees hotter than the previous high-temperature superconductivity record set last year.Room-Temperature Superconductivity Achieved for the First Time | Charlie Wood | October 14, 2020 | Quanta Magazine

Scientific definitions for superconductivity
The ability of certain metals or alloys to conduct an electric current with almost no resistance. Superconductivity usually occurs close to absolute zero, at temperatures approaching -459.67°F (-273.15°C), but has also been observed at temperatures as high as -200°F (-128.88°C).
- superconductor noun

Cultural definitions for superconductivity (1 of 2)
A property of some materials in which their electrical resistance drops to zero, and they acquire the ability to carry electric current (see also current) with no loss of energy whatsoever. Formerly, materials developed superconductivity only at temperatures near absolute zero, but new materials have been found that remain superconductive at temperatures above those of liquid nitrogen. The goal of current research is to find a material that remains superconductive at room temperature.
