Sep 23, 2004 · ence of one volt across a typical 10–8 cm interfacial boundary amounts to a potential gradi-ent of 100 million volts per centimeter— a very significant value indeed! Interfacial potentials are not confined to metallic electrodes immersed in solutions; they can in fact exist between any two phases in contact, even in the absence of chemical ...
