Important scientific discovery. A group of researchers at the University of Rochester has created a superconducting material at a temperature and pressure low enough to be used in practical applications.
The team of scientists, led by Ranga Dias, Associate Professor of Mechanical Engineering and Physics, underlined that “with this material came the dawn of environmental superconductivity and applied technologies”.
At work, published in the prestigious scientific journal NatureResearchers describe a nitrogen-doped lutetium hydride (NDLH) that exhibits superconductivity at 20.5 degrees Celsius and 10 kilobars (145,000 pounds per square inch, or psi) of pressure.
as collected Europa PressWhile 145,000 psi may seem like an extraordinarily high pressure (sea level pressure is about 15 psi), strain engineering techniques commonly used in chipmaking, for example, incorporate materials that are held together by internal chemical pressures. even bigger.
Scientists have been trying to achieve this breakthrough in condensed matter physics for over a century. Superconducting materials have two main properties: electrical resistance disappears and ejected magnetic fields pass around the superconducting material.
Possible uses of discovery
Some of the applications of this new superconducting material would be:
- Power grids that transmit electricity without the loss of up to 200 million megawatt hours (MW/h) of energy that is now produced due to the resistance of wires.
- Frictionless, levitating high-speed trains.
- More accessible medical imaging and scanning techniques such as MRI and MRI.
- Faster and more efficient electronics for digital logic and memory device technology.
- Tokamak machines that use magnetic fields to confine plasmas and achieve fusion as an unlimited energy source.
Review of a previous work
Dias’ team has already led the creation of two materials – carbonaceous sulfur hydride and yttrium superhydride – which are superconducting at 58 degrees Fahrenheit/39 million psi and 12 degrees Fahrenheit/26 million psi, respectively, in articles published in Nature It is physical review letters.
Given the importance of the new discovery, Dias and his team went to great lengths to document their research and avoid the criticisms that arose from the previous article in Natureprompting the magazine’s editors to recant, reports the University of Rochester.
Dias specified that the previous article was forwarded to Nature with new data that validate the previous work. The new data was collected outside the lab, at Argonne and Brookhaven National Laboratories, in front of an audience of scientists who witnessed the superconducting transition live. A similar approach was taken with the new work.
“The path to superconducting consumer electronics, power transfer lines, transportation and significant improvements in magnetic confinement for fusion are already a reality,” Dias said in a statement. “We believe that we are already in the modern era of superconductors”, added the expert.
