The paper aims at a molecular understanding of thermodiffusion (the Ludwig–Soret effect) in a liquid binary mixture. To … thermodiffusion. The force driving thermodiffusion arises from Onsager’s reciprocity theorem in non-equilibrium thermodynamics: it is … explicit kinetic expression is given of the force driving thermodiffusion; it involves the interaction cross-section of the two …

shed light on thermodiffusion (the Ludwig–Soret effect), which often combines inhomogeneities of both kinds. Finally, a … limitation of the Lorentz picture of transport in accounting for thermodiffusion is outlined. …

We experimentally investigate the scaling probability distributions of various intrachain distances of granular chains … in two-dimensional static packing, the chain length of which ranges from N=64 to 2048. With the scaling method proposed … in the polymer theory, the scaled data from granular chains tend to cluster together so as to form a single experimental …

/solvent molecular size ratio. The results of the theory are shown to accord well with experiments on polymer solutions in regard to both …

presence of temperature gradients. It is found that temperature gradients not only introduce a thermophoresis force, but also … compared with each other and with the thermophoresis force. …

Thermodiffusion of particles suspended in a pure liquid is a thorny problem which has not yet received a solution … relative to the carrier fluid. Focussing on thermodiffusion, we show that the osmotic pressure is irrelevant and that … thermodiffusion cannot have but two distinct origins : the temperature dependence of the stress associated with the distorted particle …
