And one more effect of the potential on the properties of the near-electrode region: The recently published works presents data on a significant change in near -sur face fr ict ion, with a reversible switching between super lubricity and high-friction states, by varying the surface's potential (EC-AFM, gold surface, water electrolyte 0.1 M NaCl). The results, compared with changes in viscosity η S = F(L), are explained by near-surface reorientation of water molecules. It has been noted that directed change of interfacial friction by electrical stimulation may have far-reaching impacts on many important fields of science and technology related to friction, adhesion, and wear.
