Nanofluidic systems exhibit transport characteristics that have made technological marvels such as desalination and energy harvesting possible by virtue of their ability to influence small currents due to selective ion transport. Traditionally, these applications have relied on nanoporous membranes whose complicated geometries impede a comprehensive understanding of the underlying physics. To bypass the associated difficulties, we consider the simpler nanochannel array and elucidate the effects…

Bipolar Nanochannels: A Systematic Approach to Asymmetric Problems.

The systematic approach taken in this work can be used to further elucidate the complicated behavior of the current-voltage response of nanofluidic diodes and to rationalize experimental results.

Sub-additive ionic transport across arrays of solid-state nanopores

It is reported that, in contrast to naive expectations, long-range mutual interaction across an array of nanopores leads to a non-extensive, sub-linear scaling of the global conductance on the number of pores N.

Electrical Resistance of Nanochannel-Microchannel Systems: An Exact Solution

Current paradigm suggests that the Ohmic electrical response of nanochannel-microchannel systems is determined solely by the nanochannel while the effects of the adjacent microchannels are…

Tunable Nanopore Arrays as the Basis for Ionic Circuits.

The modeling of ion transport through small arrays of nanopores consisting of 3, 6, and 9 nanopores and an integrated gate electrode placed on the membrane surface next to one pore opening shows that by tuning the gate voltage and strategically placing nanopores with nonlinear current-voltage characteristics, the local signal at the gate affects ionic transport through all nanopores in the array.

Enhanced nanofluidic transport in activated carbon nanoconduits

Carbon has emerged as a unique material in nanofluidics, with reports of fast water transport, molecular ion separation and efficient osmotic energy conversion. Many of these phenomena still await…

Controlling ion transport through nanopores: modeling transistor behavior.

Qualitative agreement between PNP and LEMC results indicates that mean-field electrostatic effects predominantly determine device behavior and the scaling behavior of the device as a function of the Rpore/Ξ»D parameter.

An asymptotic solution is derived, which shows remarkable correspondence to simulations of the non-approximated equations, and it is shown that the uniform potential model is only an approximation for the exact solution for small surface charges.

Electrical Conductance of Charged Nanopores

A nanopore’s response to an electrical potential drop is characterized by its electrical conductance, . For the last two decades, it has been thought that at low electrolyte concentrations, , the…
