On linear and nonlinear diffusion in liquids according to linear nonequilibrium thermodynamics

The derivation of the description of diffusive-convective transport from the linear non-equilibrium thermodynamics (LNT) by Kedem and Katchalsky (KK, 1958) yields a nonlinear diffusion equation (with diffusivity parameter proportional to solute concentration) whereas experimental data frequently can...
