Diffusiophoresis is a term used to describe the motion of colloid particles in a fluid due to a solute concentration gradient. There are several synonyms for this phenomenon including Soret effect, thermal diffusion, and thermal diffusion potential. Other related terms include thermophoresis, which is the motion of particles due to a temperature gradient, and electrodiffusion, which involves the motion of charged particles under the influence of an electric field. Diffusiophoresis plays an important role in many natural and industrial processes, and understanding these synonyms and related terms can help scientists improve their understanding of these fields.
