The editors have retracted this article [1] because after publication concerns were raised regarding the validity of the conclusions drawn. Post-publication peer review has revealed that the experimental procedure is not described adequately, that the assignment of the signals in the Fourier-Transform infrared spectra are partially wrong, and that the mechanism proposed for the effect of the applied voltages on the surface tension is not justified by the data. The main claim of the paper cannot be reliably reached. All authors do not agree to this retraction.
