T he Soret effect, also known as thermodiffusion, is a classic example of coupled transport (1) in which directed motion of a particle or macromolecule is driven by f low of heat down a thermal gradient. Generally, a particle moves from hot to cold, but the reverse is also seen under some conditions. Although it has been known for 150 years, the microscopic explanation of the Soret effect has r...

The role of thermodiffusive generation of concentration fluctuations via the Soret effect, their contribution to the buoyancy forces that drive convection, the advective mixing effect of the latter, and the diffusive homogenisation are compared and elucidated for oscillatory convection. Numerically obtained solutions of the field equations in the form of spatially extended relaxed traveling wav...

A microscopic approach is presented to describe the contribution to the thermal diffusion coefficient of colloids due to intercolloidal particle interactions. An exact expression for the leading-order virial coefficient of the thermal diffusion coefficient of interacting colloidal spheres is derived in terms of the intercolloidal pair-interaction potential and hydrodynamic interaction functions...

The tremendous amount of wasted heat from solar radiation and industry dissipation has motivated the development thermoelectric concepts that directly convert into electricity. main challenge in practical applications for thermoelectrics is high cost both materials manufacturing. Recently, breakthrough progresses ionic open up new possibilities to charge energy storage devices when submitted a ...
