Testing predictions in electrochemical nanosystems
Physicists at the Technische Universitaet Muenchen 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. They say their method accounts for effects that macroscopic models can't explain and is general enough to address a variety of research questions beyond those concerning nanoelectrodes. (2010-06-07)
