Abstract

We developed a measurement method of a streaming potential in a few hundreds nanometer-sized channel (called extended-nano space) and evaluated the relationship between proton and silanol groups on glass surface. We discussed relationship between proton transfer phase [1] and introduced proton by investigating pH dependence. We found unique surface state in extended-nano space for the first time, and this discussion will be important for evaluation of surface reaction.
