Finally, superconductivity was achieved at room temperature



Summary

After decades of searching, this week researchers announced the creation of the first superconductor that does not need to be cooled to make its electrical resistance disappear. There’s a catch: The new room-temperature superconductor only works at a pressure equivalent to about three-quarters of that in the center of the Earth. To achieve this pressure, the material – a mixture of hydrogen, sulfur and carbon – was crushed between the flat tips of two diamonds. Now, if researchers can stabilize the material at ambient pressure, the dreamed applications of superconductivity could be achieved, such as low-loss power lines and super-powerful superconducting magnets that do not require cooling, for MRI machines and maglev trains.
