Solvophoresis
Solvophoresis is a spontaneous motion of dispersed particles in a mixed solvent induced by a gradient of solvent concentration. Solvophoresis was experimentally established by Marek Kosmulski and Egon Matijevic.M.Kosmulski, E.Matijevic, ''Solvophoresis of latex'', Journal of Colloid and Interface Science 150, 291-294 (1992) Solvophoresis is similar to diffusiophoresis Diffusiophoresis is the spontaneous motion of colloidal particles or molecules in a fluid, induced by a concentration gradient of a different substance. In other words, it is motion of one species, A, in response to a concentration gradient in ano .... References Colloidal chemistry {{physical-chemistry-stub ...

Egon Matijevic
Egon Matijevic (27 April 1922 – 20 July 2016) was an American chemist. He earned his B.Sc. and Ph.D. in chemistry from the University of Zagreb. After specialization at the University of Cambridge he continued to work at the Clarkson University. He is the author of more than 550 scientific papers in colloidal and surface chemistry with numerous applications in medicine and industry. Matijevic was a member of American Chemical Society, American Association for Crystal Growth, World Academy of Ceramics, International Association of Colloid and Interface Scientists and honorary member of American Ceramic Society, German Colloid Society, Chemical Society of Japan The (CSJ) is a learned society and professional association founded in 1878 in order to advance research in chemistry. The mission of the CSJ is to promote chemistry for science and industry in collaboration with other domestic and global societ ... and Materials Research Society of Japan.

Diffusiophoresis
Diffusiophoresis is the spontaneous motion of colloidal particles or molecules in a fluid, induced by a concentration gradient of a different substance. In other words, it is motion of one species, A, in response to a concentration gradient in another species, B. Typically, A is colloidal particles which are in aqueous solution in which B is a dissolved salt such as sodium chloride, and so the particles of A are much larger than the ions of B. But both A and B could be polymer molecules, and B could be a small molecule. For example, concentration gradients in ethanol solutions in water move 1 μm diameter colloidal particles with diffusiophoretic velocities _ of order 0.1 to 1 μm/s, the movement is towards regions of the solution with lower ethanol concentration (and so higher water concentration). Both species A and B will typically be diffusing but diffusiophoresis is distinct from simple diffusion: in simple diffusion a species A moves down a gradient in its own concentration. ...
