stiffness was determined and is attributed to the reported solidification of the hydration layers.
Keywords: atomic force microscopy; hydration; pulse-response; quality-factor control; viscoelasticity; Introduction
Liquid solvation is a phenomenon common to a large variety of liquid–solid interfaces [1
disadvantageous with respect to the signal-to-noise ratio. In the previous report of the step-response measurement the inferior signal-to-noise ratio of the signal hindered detailed analysis. In the present report a pulse-response measurement in which differentiation of the response signal can be dispensed with
