A unified description of colloidal thermophoresis [PDF]
The European Physical Journal E, 2018 We use the dynamic length and time scale separation in suspensions to formulate a general description of colloidal thermophoresis. Our approach allows an unambiguous definition of separate contributions to the colloidal flux and clarifies the physical mechanisms behind non-equilibrium motion of colloids.

Hydrodynamic interactions in DNA thermophoresis [PDF]
Soft Matter, 2018 Hydrodynamic interactions result in molecular-weight dependence of DNA thermophoresis and strong specific-ion effects.

Anisotropic thermophoresis [PDF]
Soft Matter, 2017 The thermophoretic force on an elongated colloid oriented with the temperature gradient can be larger or smaller than when oriented perpendicular to it. This anisotropy can translate into a non-vanishing thermophoretic force in the direction perpendicular to the temperature gradient.

Thermophoresis in colloidal suspensions
Journal of Physics: Condensed Matter, 2008 Thermophoresis is particle motion induced by thermal gradients. Akin to other driven transport processes, such as the Soret effect in simple fluid mixtures, or electrophoresis and diffusiophoresis in colloidal suspensions, it is, both experimentally and theoretically, a challenging subject.

Biotechnological applications of thermophoresis [PDF]
, 2011 For over 150 years it is known that particles in a temperature gradient conduct a directed movement. This is called the Soret effect or thermophoresis. Still the underlying physical principles of thermophoresis in aqueous solutions are not totally understood.

Thermophoresis or When Small Objects Meet Temperature Gradient: Numerous Applications [PDF]
Kemija u Industriji, 2023 This mini review discusses the phenomenon of thermophoresis, also known as the thermophoretic effect. Thermophoretic effect arises from the combination of a temperature gradient and particles of very small dimensions, on the order of magnitude of the ...

Modelling Thermophoresis in Nanofluids
Proceeding of 9th Thermal and Fluids Engineering Conference (TFEC)Nanoparticles are being used in fluids to enhance the thermal conductivity, but published results are inconsistent. A possible explanation for this inconsistency is that nanoparticles may migrate under the action of temperature gradient counteracting Brownian diffusion.

Thermophoresis in Colloidal Suspensions
, 2018 This dissertation examines the motion of colloids in a temperature gradient, a non-equilibrium phenomenon also known as thermophoresis. Chapter 1 gives an introduction to the existing applications and basic concepts of thermophoresis and outlines some of the experimental and theoretical challenges that serve as a motivation for this PhD project.

Thermophoresis: The Case of Streptavidin and Biotin [PDF]
Polymers, 2020 Thermophoretic behavior of a free protein changes upon ligand binding and gives access to information on the binding constants. The Soret effect has also been proven to be a promising tool to gain information on the hydration layer, as the temperature dependence of the thermodiffusion behavior is sensitive to solute–solvent interactions.
