measurements are demonstrated in ionically-active (polar isopropanol, milli-Q water and aqueous NaCl) and ionically-inactive (non-polar decane) liquids by electrochemicalforcemicroscopy (EcFM), a multidimensional (i.e., bias- and time-resolved) spectroscopy method.

Many important physical, chemical and biological processes including wetting, adsorption, electronic transfer
measurements in air and milli-Q water are compared to illustrate the infeasibility of implementing KPFM in ionically-active liquids. A multidimensional (i.e., bias- and time-resolved) spectroscopy method, referred to as electrochemicalforcemicroscopy (EcFM) [38], is subsequently investigated for performing
