Based on the capillary pore model (space-charge theory) for combined fluid and ion flow through cylindrical nanopores or nanotubes, we derive the continuum equations modified to include wall slip. We focus on the ionic conductance and streaming conductance, cross-coefficients of relevance for electrokinetic energy conversion and electro-osmotic pumping. We combine the theory with a Langmuir-Stern 1-pK charge regulation boundary condition resulting in a non-monotonic dependence of the cross…

Transport of ions in hydrophobic nanotubes

The theory of electrokinetic ion transport in cylindrical channels of a fixed surface charge density is revisited. Attention is focused on impact of the hydrophobic slippage and mobility of adsorbed

AC-driven electro-osmotic flow in charged nanopores

In this paper we report the theory describing the electro-osmotic flow in charged nanopores with constant radius and charge density driven by alternating current. We solve the ion and solution

Role of charge regulation and flow slip in the ionic conductance of nanopores: An analytical approach.

This work proposes an analytical approach to the ionic conductance in nanopores that takes into account electro-osmotic effects, and catalogs the different possible transport regimes and proposes an explanation for the wide variety of currently known experimental behavior.

Liquid-Solid Slip on Charged Walls: The Dramatic Impact of Charge Distribution.

The dramatic impact of surface charge distribution on the slip-charge coupling is shown, providing new fundamental insight into the molecular mechanisms of liquid-solid slip, and practical guidelines for searching new functional interfaces with optimal energy conversion properties, e.g., for blue energy or waste heat harvesting.

Pore‐scale Study of Ion Transport Mechanisms in Inhomogeneously Charged Nanoporous Rocks: Impacts of Interface Properties on Macroscopic Transport

The electrokinetic transport mechanisms of multispecies ions through 3‐D nanoporous rocks with chemical reaction at the solid‐aqueous solution interfaces are investigated. We systematically study the

Freezing point depression and freeze-thaw damage by nanofluidic salt trapping

A remarkable variety of organisms and wet materials are able to endure temperatures far below the freezing point of bulk water. Cryo-tolerance in biology is usually attributed to "anti-freeze"
