The Soret effect describes diffusive motion that originates from a temperature gradient. It is
observed in mixtures of gases, liquids and even solids. Although there is a formal …

Molecules drift along temperature gradients, an effect called thermophoresis, the Soret
effect, or thermodiffusion. In liquids, its theoretical foundation is the subject of a long …

A temperature gradient acts like an external field on colloidal suspensions and drives the
solute particles to the cold or to the warm, depending on interfacial and solvent properties …

Thermodiffusion, also called thermal diffusion or the Ludwig–Soret effect, describes the
coupling between a temperature gradient and a resulting mass flux in a multicomponent …

Quantification of biomolecular binding reactions in their native environment is crucial for
biology and medicine. However, reliable methods are rare. We have developed a new …

With rising popularity of microscale thermophoresis for the characterisation of protein-ligand
binding reactions and possible applications in microfluidic devices, there is a growing …

We use a micrometer-scale optical beam deflection technique to measure the
thermodiffusion coefficient DT at room temperature (≈ 24° C) of dilute aqueous suspensions …

An expression for the single-particle thermal diffusion coefficient of a charged colloidal
sphere is derived on the basis of force balance on the Brownian time scale in combination …

Measurements of particle flows driven by temperature gradients are conducted as a function
of temperature on aqueous suspensions of polystyrene nanoparticles and proteins of T4 …
