When a direct current (DC) electric field is applied across an ion-selective nanoporous
membrane or a nanochannel with an overlapping Debye layer, a surprising microvortex …

When integrated into microfluidic chips, ion-selective nanoporous polymer and solid-state
membranes can be used for on-chip pumping, pH actuation, analyte concentration …

For about 60 years, it is known that “limiting current” density does not really limit the current
density in electrodialysis (ED). The use of intensive currents allows one to decrease the area …

In this paper, the microscale experimental model system for studying electrodialysis (ED)
process is described, which is used for visualizing in situ fluid flow and concentration profile …

Direct evidence is provided for the transition from surface conduction (SC) to electro-osmotic
flow (EOF) above a critical channel depth (d) of a nanofluidic device. The dependence of the …

The physisorption of negatively charged single-stranded DNA (ssDNA) of different lengths
onto the surface of anion-exchange membranes is sensitively shown to alter the anion flux …

Ion concentration polarization focusing (ICPF) is an electrokinetic technique, in which
analytes are enriched and separated along a localized electric field gradient in the presence …

Surface properties were measured together with electrochemical characteristics of a CMX
(Neosepta, Tokuyama Corp.) cation-exchange membrane. Relative hydrophobicity was …

Nanofluidic devices act a critical role in many inter-/multidisciplinary research fields
including single-molecule DNA sequencing and (bio-) chemical detection because of their …

Ion-exchange systems represented, for example, by ion-exchange membranes or ion-
exchange resin particles exhibit nonlinear current-voltage curves on which one finds three …
