Why molecules move along a temperature gradient

S Duhr, D Braun - Proceedings of the National Academy of …, 2006 - National Acad Sciences
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 …

Field-flow fractionation techniques for polymer and colloid analysis

H Cölfen, M Antonietti - New developments in polymer analytics I, 2000 - Springer
Field-flow fractionation (FFF) is a family of flexible analytical fractionating techniques which
have the great advantage that separation is achieved solely through the interaction of the …

Thermophoretic depletion follows Boltzmann distribution

S Duhr, D Braun - Physical review letters, 2006 - APS
Thermophoresis, also termed thermal diffusion or the Soret effect, moves particles along
temperature gradients. For particles in liquids, the effect lacks a theoretical explanation. We …

Measuring colloidal and macromolecular properties by FFF

JC Giddings - Analytical chemistry, 1995 - ACS Publications
FI ield-flow fractionation (FFF) is a family of chromatographic-like elution techniques in which
an external field or gradient, rather than partitioning betweenphases, causes differential …

Observation of slip flow in thermophoresis

FM Weinert, D Braun - Physical review letters, 2008 - APS
Two differing theories aim to describe fluidic thermophoresis, the movement of particles
along a temperature gradient. While thermodynamic approaches rely on local equilibrium …

Soret feedback in thermal diffusion of suspensions

NV Tabiryan, W Luo - Physical Review E, 1998 - APS
We have theoretically studied the interaction of a light beam with liquids containing
absorbing nanoparticles. We have shown that the Soret effect ensures a feedback that …

Elementary kinematical model of thermal diffusion in liquids and gases

H Brenner - Physical Review E—Statistical, Nonlinear, and Soft …, 2006 - APS
An elementary hydrodynamic and Brownian motion model of the thermal diffusivity DT of a
restricted class of binary liquid mixtures, previously proposed by the author, is given a more …

Overview of field‐flow fractionation

MN Myers - Journal of Microcolumn Separations, 1997 - Wiley Online Library
Foremost among JC Gidding's many contributions to separation science is the invention and
development of field‐flow fractionation. This article is a nonmathematical overview of field …

Thermophoresis of charged colloidal particles in aqueous media–Effect of particle size

Y Zhou, C Yang, YC Lam, X Huang - International Journal of Heat and Mass …, 2016 - Elsevier
We investigated the particle size effect on the thermophoresis of colloidal particles in an
aqueous medium via a microfluidic approach. A microfluidic device was used to directly …

Convection and thermodiffusion of colloidal gold tracers by laser light scattering

W Schaertl, C Roos - Physical Review E, 1999 - APS
In a dynamic light scattering experiment, we have investigated the time intensity correlation
function and the profile of the transmitted laser beam for organic dispersions of light …
