FIG. 1.

Schematic illustration of a nanoslit-capillary filling experiment. A nanoslit capillary, of height and width several micrometers is filled with liquid from an attached reservoir by capillary action. The length of the fluid plug—the position of the liquid meniscus— is recorded as function of time .

FIG. 2.

Plot of the apparent viscosity vs normalized channel height for increasing values of the the ratio between the electro-osmotic mobility and the viscous mobility , 0.5, 1, and 2 (solid lines from below). The solid data points show experimental results reproduced from Ref. 9 for demiwater with (left group of data) and NaCl solution with (right group of data). The open data points show corresponding results for NaCl reproduced from Ref. 14 with the dashed line being a fit to the data with used as fitting parameter.
