Recent advances in thermodiffusion (Soret effect) in binary and higher multicomponent
liquid mixtures are reviewed. The mixtures studied include the hydrocarbon, associating …

We present a model that relates isotope effects in thermodiffusion to changes in internal
degrees of freedom associated with rotational and vibrational motion. The model uses …

We extend our nonequilibrium thermodynamic model of thermodiffusion in binary systems to
multi-component mixtures. The fundamental parameter is the difference in molecular entropy …

We present a model that explains variance in the thermodiffusion of hydrocarbon isomers in
binary liquid mixtures. The model relies on material transport equations for binary …

The material transport equations derived by non-equilibrium thermodynamics are used to
describe the material transport in binary non-isothermal molecular systems. The chemical …

We analyze a microfluidic pump from the literature that utilizes a flat channel with boundary
walls at different temperatures and tilted elongated pillars within in order to construct an …

We analyze existing models for material transport in non-isothermal non-electrolyte liquid
mixtures that utilize non-equilibrium thermodynamics. Many different sets of equations for …

This chapter outlines a theoretical framework for the microscopic approach to material
transport in liquid mixtures, and applies that framework to binary one-phase systems. The …

Isotope effects in the thermodiffusion of dilute atomic liquids are examined using a non-
equilibrium thermodynamic model, where the thermodynamic parameters are calculated …
