Figure 1: The formation of CICP zone.
From: Capillarity ion concentration polarization as spontaneous desalting mechanism
(a) The snapshots of a fluid flow driven by nanoporous hydrogel (see Supplementary Video 1) and (b) the plot of measured imbibition lengths as a function of time. The imbibition velocity is also plotted in the inset. (c) The confocal microscopic image of accumulating fluorescent dyes at the top corner of microchannel, confirming the formation of an ion-depletion zone at the bottom of microchannel.
