TECHNOLOGY REVIEW: 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 claimthat 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.
Followers of this blog will have read about this work last December, when it was first posted to the arXiv. At the time, physicists were cautious about the work. The history of superconductivity is littered with dubious claims of high-temperature activity that later turn out to be impossible to reproduce.
But in the months since then, Eremets and co have worked hard to conjure up the final pieces of conclusive evidence. A few weeks ago, their paper was finally published in the peer reviewed journal Nature, giving it the rubber stamp of respectability that mainstream physics requires. Suddenly, superconductivity is back in the headlines.
