Nanoclusters Break Superconductivity Record
KentuckyFC writes "A couple of years ago, two Russian physicists predicted that metal nanoclusters with exactly the right number of delocalized electrons (a few hundred or so) could become strong superconductors. Now an American group has found the first evidence that this prediction is correct in individual aluminum nanoclusters containing 45 or 47 atoms. And they found it at 200 K (abstract). That's a huge jump over the previous record of 138K for a high-temperature superconductor. There are a few caveats, however. The result is only partial evidence of superconductivity and the work has yet to be peer-reviewed. But its mere publication will set scientists scrambling to confirm. And 200K! That's practically room temperature in the Siberian winter." http://slashdot.org/slashdot-it.pl?f.../04/11/1422259
