Wann ein Metallteilchen den elektrischen Widerstand verliert, ist auch eine Frage seiner Groesse. Die Temperatur, unterhalb derer ein Material zu einem Supraleiter wird, kann naemlich drastisch steigen - wenn der Stoff als Nanokuegelchen mit bestimmtem Durchmesser vorliegt.

In previous experiments the photons were confined to fiber channels a few hundred meters long to ensure their state remained unchanged, but in the new experiments pairs of photons were entangled and then the higher-energy photon of the pair was sent through a free space channel 16 km long.

Physicists at the Technische Universitaet Muenchen (TUM) are gearing up for experimental tests of findings they arrived at through theoretical considerations: that electrochemical reactions take place more rapidly on isolated, nanometer-scale electrodes than on their familiar macroscopic counterparts, and that this surprising behavior is caused by thermal noise.
