Abstract

We report multi-step mixing of aqueous solutions of different ion concentration in a T-shaped nanochannel, where symmetry of mixing was broken by the ion hydration effect. When the ion species is K+ of small hydration radius, the fluidic resistance was increased as pure water probably due to different liquid structure by loosely coupled water molecules by the confinement, while Na+ and Li+ of large hydration radius made the fluidic resistance same as the bulk. The present study will contribute to develop nanofluidic systems for integration of chemical processes.
