Ion-Enrichment and Ion-Depletion Effect of Nanochannel Structures
Abstract
Unique properties exist in nanofluidic channels. In this paper, we report a new phenomenon, ion enrichment/depletion, associated with nanochannel structures. As a voltage is applied across a nanochannel, ions are rapidly enriched at one end and depleted at the other end of the nanochannel. The degree of this enrichment and depletion is directly related to the extent of double-layer overlap. A simple model is presented to qualitatively interpret this phenomenon.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
