Abstract

  Recent development of technique of microscopic measurement of solid-liquid interface structure has revealed solvent structure formed on inorganic crystals and organic molecules. In this manuscript, we show the examples of observation of three-dimensional distribution of water molecules with molecular-scale in the vicinity of calcium carbonate crystals and clay mineral surfaces by using the frequency modulation atomic force microscopy (FM-AFM) working in liquid. We discuss prospects of the microscopic measurement of solid-liquid interfaces while introducing the local change of hydration structure by additives through the observation of calcium carbonate, and the dependency of hydration structure on cations through the observation of clay minerals, respectively.
