The present work focuses on the effects of ion or fluid motions at solid-liquid or gas-liquid interfaces on flow characteristics. For solid-liquid interfacial phenomena, the novel velocity measurement technique with a depthwise spatial resolution of the order of nanometer was developed by combining the molecular tagging with the evanescent wave illumination. This technique reveals the effect of the molecular structure at a solid surface on the electric double layer. For gas-liquid interfacial phenomena, ultra-high-speed micron-resolution particle tracking velocimetry was advanced, and the relationship between the microbubble generation process and the flow characteristics was quantitatively evaluated.
