ac mode image of the HTS colloidal probe at the point of contact.
(a) Residuals from fitting V-theory to run five in decanol using the HTS system; in situ (upper line), residuals (middle), and thermal ( calibrated in air) (lower). (b) Residuals for octane and hexadecane using fixed for HTS system.
(a) Force, (b) velocity, and (c) expansion representation [Eq. (7)] for decanol run five HTS system. Inset A demonstrates that hard contact was made on approach at zero separation.
