Physics.
- : 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.
Examples
Over the next few decades superconductivity was found in other super-cooled materials, and in 1933 researchers discovered that superconductors also expel magnetic fields.
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.
For many decades afterwards, superconductivity was created only at extremely low temperatures.
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.
That’s more than 50 degrees hotter than the previous high-temperature superconductivity record set last year.
