TL;DR: In this article, the effects of electroosmotic flow (EOF) on the ionic current rectification (ICR) phenomenon in conical nanopores are studied comprehensively with use of a continuum model, composed of Nernst−Planck equations for ionic concentrations, the Poisson equation for the electric potential, and Navier−Stokes equations for the flow field.

TL;DR: Electrokinetic ion transport in a pH-regulated nanopore, taking into account both multiple ionic species and charge regulation on the nanopore wall, is theoretically investigated for the first time.

TL;DR: In this article, electric field-induced ion transport and the resulting conductance in a polyelectrolyte-modified nanopore were theoretically studied using a continuum-based model, composed of coupled Poisson-Nernst-Planck (PNP) equations for the ionic mass transport, and Stokes and Brinkman equations for hydrodynamic fields in the exterior and interior of the PE layer, respectively.

TL;DR: The proposed soft nanopore is capable of enhancing the performance of DNA translocation while maintaining its basic signature of the ionic current at high salt concentration and provides the necessary information for designing devices used in DNA sequencing.

TL;DR: In this article, the authors investigate the effectiveness of heterogeneity-induced trapping mechanism, in potential synergy with a self-sealing gravitational trapping mechanism for secure CO2 storage in marine sediments.
