Superconducting materials typically require extremely cool temperatures to operate, which is demonstrated in this photo. But a new discovery could change that
Since its discovery more than a century ago, superconductivity has come to play a powerful role in many modern day technologies, such as maglev trains and MRI scans, but its utility has been limited by the need for extremely cool operating temperatures. Scientists are now claiming a big breakthrough in this area, creating what they say is the first material capable of superconductivity at room temperature.
The work was led by Ranga Dias at the University of Rochester, and aims to overcome one of the major roadblocks in expanding the uses of superconductive materials. These materials exhibit no electrical resistance and expel a magnetic field, but because they typically only function at temperatures below -140 °C (-220 °F), they require expensive equipment to maintain.
“Because of the limits of low temperature, materials with such extraordinary properties have not quite transformed the world in the way that many might have imagined,” says Dias. “However, our discovery will break down these barriers and open the door to many potential applications.”
