abstract = {Chemical gradients maintained along surfaces can drive
fluid flows by diffusio-osmosis, which become significant at
micro- and nano-scales. Here, by means of mesoscopic
simulations, we show that a concentration drop across
microchannels with periodically inhomogeneous boundary walls
can laterally transport fluids over arbitrarily long
distances along the microchannel. The driving field is the
secondary local chemical gradient parallel to the channel
induced by the periodic inhomogeneity of the channel wall.
The flow velocity depends on the concentration drop across
the channel and the structure and composition of the channel
walls, but it is independent of the overall channel length.
Our work thus presents new insight into the fluid transport
in long microchannels commonly found in nature and is useful
for designing novel micro- or nano-fluidic pumps.},
