Room-Temperature Superconductivity Achieved for the First Time :
DEFINITION: A room-temperature superconductor is a material that is capable of exhibiting superconductivity at operating temperatures above 0 °C (273 K; 32 °F).
Physicists have reached a long-sought goal. The catch is that their room-temperature superconductor requires crushing pressures to keep from falling apart.
A novel metallic compound of hydrogen, carbon and sulfur exhibited superconductivity at a balmy 59 degrees Fahrenheit when pressurized between a pair of diamond anvils.
The hydrogen, carbon and sulfur compound operates as a superconductor at up to 59 degrees Fahrenheit, the team reported today in Nature. That’s more than 50 degrees hotter than the previous high-temperature superconductivity record set last year.
Yet while researchers celebrate the achievement, they stress that the newfound compound — created by a team led by Ranga Dias of the University of Rochester — will never find its way into lossless power lines, frictionless high-speed trains, or any of the revolutionary technologies that could become ubiquitous if the fragile quantum effect underlying superconductivity could be maintained in truly ambient conditions. That’s because the substance superconducts at room temperature only while being crushed between a pair of diamonds to pressures roughly 75% as extreme as those found in the Earth’s core.
