Abstract

Surface forces measurement is a powerful tool for molecular level of characterization of solid-liquid interfaces and complex systems. In this review, we report the development of novel nano-scale measurements based on surface forces apparatus (SFA): (1) Twin-path SFA, which enabled us to study wide variety of samples such as metals and ceramics. (2) The resonance shear measurement (RSM), which is a sensitive method for evaluating properties of confined liquids for nano-rheology and tribology. We also summarize some of our recent researches on (1) evaluation of a surface potential and charge density of the electrodes using electrochemical surface forces apparatus, (2) characterization of ionic liquids confined between silica surfaces.
