Fig. 1From: Effect of evaporation through nanoporous medium on diffusiophoresisa The schematic of spontaneous particle exclusion zone induced by diffusiophoreis near the nanoporous medium. Uimb is the imbibition velocity, UDP is the diffusiophoretic velocity, Uevap is the velocity induced by evaporation through the medium. LPDMS is the distance of PDMS between the channel and the medium exposed to air (the location of starting evaporation). Fabricated devices of LPDMS: b 1 cm and c 250 μmBack to article page
