source channel enter the nanochannel from one side and move toward electrode 1 from the
other, such that the anion concentration on the left side of the source-nano junction region
( t = 26 ms, -20 µm < y < 0 µm) is lower than that of the cations, causing the observed
asymmetric charge distribution. As recovery progresses the asymmetry dissipates.
Figure 4.11 Streamlines (at t = 15ms) near the micro-nano junction regions showing the vortices developed
due to opposing electroosmotic and pressure driven flows in the microchannel. Top: near the
junction of the source channel and the nanochannel. Bottom: near the junction of the receiving
channel and the nanochannel. Adapted from Jin, X., et al. Induced electrokinetic transport in
