Visualization of capillary wicking tests. (a) A schematic for the experimental set-up of the capillary wicking. The propagated liquid rises as a function of time which is captured with a camera and then plotted. (b) A representative plot of a typical measured wicking height h from a copper IO with a pore diameter of 1000 nm. The dashed line is the numerical trend estimated using Darcy’s Law. (c) Time evolution images of a copper IO wicking up deionized water. The blue line is a guide for the effective wicking height h eff starting from the average of the meniscus’s top edge.
