Diffusiphoresis

Diffusiophoresis is a motion of dispersed particles in a fluid induced by a diffusion gradient of molecular substances that are dissolved in the fluid. This gradient affects structure of the particles in an interfacial double layer and causes sliding motion of the fluid relative to the particle surface. Diffusiophoresis was theoretically predicted and experimentally established by B. V. Derjaguin and others in 1947.^[1]

Capillary osmosis is the effect that is reverse to diffusiophoresis, similar to the way that electro-osmosis is reverse to electrophoresis.^[2]

Diffusiophoresis is a spontaneous motion of the dispersed particle under the application of an electrolyte (nonelectrolyte) concentration gradient.
