On the Cross-diffusion and Soret Effect in Multicomponent Mixtures
Microgravity Science and Technology, 2008The model of convection in a multicomponent fluid is considered taking into account the cross-diffusion and the Soret effect. It is shown that the cross-diffusion coefficients can be eliminated by a linear change of composition and the thermal diffusion coefficients.

Long-wavelength thermocapillary instability with the Soret effect
Physical Review E, 2004We study the onset of Marangoni instability of the quiescent equilibrium in a binary liquid layer with a nondeformable interface in the presence of the Soret effect. Linear stability analysis shows that both monotonic and oscillatory long-wavelength instabilities are possible depending on the value of the Soret number chi.

Effects of pH and temperature on the scanning Soret oximeter
Journal of Biomedical Engineering, 1993A new optical measurement technique based on spectral scanning (the scanning Soret oximeter) has previously been described. The technique has now been tested under extremes of physiological pH and temperature, the effects of which are shown to be negligible.

Electromigration and soret effect in cobalt
Solid State Communications, 1966Abstract The present investigation aims to examine whether the electron-ion interaction in hole conductors follows the flow of charge carriers in electromigration experiments, as predicted by theory and observed in several electron conductors. Mass transport of cobalt, a hole conductor, under the influence of a direct current of about 10 4 A

Driving forces and polymer hydrodynamics in the Soret effect
Journal of Physics: Condensed Matter, 2012A temperature gradient induces different driving forces on the components of a mixture which translates into their segregation. We show that these driving forces constitute the physical picture behind the thermodiffusion effect, and provide an alternative expression of the Soret coefficient which can be applied to both colloidal suspensions and ...

The Soret effect in diffusion in crystals
Acta Materialia, 2008Abstract The Soret effect, as it occurs in the diffusion of solutes in crystals, is analyzed using the principle of microscopic reversibility whereby an approach is developed for interpreting and computing Q ∗ , the heat of transport. To compute the transport of energy during the diffusion jump process, and then Q ∗ , the processes of thermal ...

Thermal Diffusion Potentials and the Soret Effect
Nature, 1954WHEN a temperature gradient is applied to a homogeneous solution of an electrolyte, there is a tendency for a concentration gradient to be established (Soret effect). The thermal diffusion potential associated with the temperature gradient should change during the establishment of the Soret equilibrium. For a cell of the type:
