Europium's Superconductivity Demonstrated

gabrlknght writes "An old element just learned a new trick under pressure. When cooled and squeezed very hard, the soft metallic element europium turns into a superconductor, allowing electrons to flow unfettered by resistance, a study appearing May 13 in Physical Review Letters shows. The results make europium the 53rd of the 92 naturally occurring elements to possess superconductivity, which, if harnessed, could make for more efficient energy transfer."

    The Carnegie Institution for Science published something like this exactly one year ago today.

    Granted, it doesn't mention Europium, but the same principle applies.

      The only difference between the last 20 or so elements is the later ones are not quite so ridiculously cold. Eventually we may get to just unbelievably cold!

      Your temperature scale is clearly incorrect.

      As it regards cold, it goes from Chilly, to Cold, to Freezing, eventually reaching Ridiculously Cold, Unbelievably Cold and Impossibly Cold.

      In certain circles where greater accuracy is required its common to use a finer precision in the jump from Freezing to Ridiculously Cold.

      This is done by having Bloody Freezing and F*****ing Freezing as additional points on the scale.

      One of the scientists in the article had a quote that I think is worth reproducing:

      "Superconductivity is an area where it's very difficult theoretically to have the last word, to really know what's possible and what's not.... Anything one can do to further the understanding of superconductivity might eventually help one design a better superconductor."

      In essence we don't know what superconductors can do, but if we try different stuff eventually we will find something useful. That's why it's worth doing.
