| Abstract: | A ternary diffusion formulation for diffusiophoresis, the migration of a particle in a solute gradient, is suggested. The formulation, derived from irr contributions in the D12 “cross-term” diffusivity. The ternary diffusion formulation allows both measurement of the magnitude of diffusioph transport situation. Measured coefficients of diffusiophoresis agree reasonably well with previous electrohydrodynamic theories. |
