Finally, superconductivity of room temperature was achieved



Summary

Fulfilling a decade-long adventure, this week researchers have reportedly created the first superconductor that should not be refrigerated for electrical resistance to disappear. There is a catch: The new room temperature superconductor will only work at a pressure equal to about three-quarters of that in the center of the Earth. To achieve that pressure, the material – a mixture of hydrogen, sulfur, and carbon – is crushed between the flat tops of the two diamonds. Now, if researchers can stabilize the material at ambient pressure, dreamed applications of superconductivity can be reached, such as low-power power lines and ultrapowerful superconducting magnets that do not require cooling, for MRI machines and maglev trains.
