Onsager reciprocity in premelting solids

Do thermal diffusion and Dufour coefficients satisfy Onsager's reciprocity relation?

It is commonly admitted that in liquids the thermal diffusion and Dufour coefficients $D_{T}$\ and $D_{F}$ satisfy Onsager's reciprocity. From their relation to the cross-coefficients of the phenomenological equations, we are led to the conclusion that this is not the case in general. As illustrative and physically relevant examples, we discuss micellar solutions and colloidal suspensions, where $D_{T}$ arises from chemical reactions or viscous effects but is not related to the Dufour coefficient $D_{F}$. The situation is less clear for binary molecular mixtures; available experimental and sim…

A simple statistical-mechanical interpretation of Onsager reciprocal relations and Derjaguin theory of thermo-osmosis

The application of a temperature gradient along a fluid-solid interface generates stresses in the fluid causing "thermo-osmotic" flow. Much of the understanding of this phenomenon is based on Derjaguin's work relating thermo-osmotic flows to the mechano-caloric effect, namely, the interfacial heat flow induced by a pressure gradient. This is done by using Onsager's reciprocity relationship for the equivalence of the thermo-osmotic and mechano-caloric cross-term transport coefficients. Both Derjaguin theory and Onsager framework for out-of-equilibrium systems are formulated in macroscopic therm…
