We describe a quantitative study of vortex generation due to non-equilibrium electrokinetics near a micro/nanochannel interface. The microfluidic device is comprised of a microchannel with a set of nanochannels. These perm-selective nanochannels induce flow instability and thereby produce strong vortex generation. We performed tracking visualization of(More)
Research interest on transportation of ion through nanoscale geometries has increased recently due to its emerging applications such as energy harvesting, biomolecule concentration/separation, water purification, chemical mixing etc. Besides of application studies using ion transportation, the fundamental research for revealing and understanding mechanism(More)
