Physicists have discovered a material that superconducts at a temperature significantly warmer than the coldest ever measured on the earth. That should herald a new era of superconductivity research.
The world of superconductivity is in uproar. Last year, Mikhail Eremets and a couple of pals from the Max Planck Institute for Chemistry in Mainz, Germany, made the extraordinary claim that they had seen hydrogen sulphide superconducting at -70 °C. That’s some 20 degrees hotter than any other material—a huge increase over the current record….
