Colloid thermophoresis in the dilute electrolyte concentration regime: from theory to experiment

D Pu, A Panahi, G Natale, AM Benneker - Soft Matter, 2023 - pubs.rsc.org
Colloid thermophoresis in aqueous media is vital for numerous applications in nanoscience
and life sciences. To date, a general description of colloid thermophoresis in DI water has …

[HTML][HTML] Temperature-induced migration of electro-neutral interacting colloidal particles

JKG Dhont, WJ Briels - Journal of colloid and interface science, 2024 - Elsevier
Migration of colloidal particles induced by temperature gradients is commonly referred to as
thermodiffusion, thermal diffusion, or the (Ludwig-) Soret effect. The thermophoretic force …

Determining phoretic mobilities with Onsager's reciprocal relations: Electro-and thermophoresis revisited

J Burelbach, H Stark - The European Physical Journal E, 2019 - Springer
We use a hydrodynamic reciprocal approach to phoretic motion to derive general
expressions for the electrophoretic and thermophoretic mobility of weakly charged colloids …

Internal degrees of freedom as a basis for isotopic effects in thermodiffusion

SN Semenov, ME Schimpf - The Journal of Physical Chemistry B, 2021 - ACS Publications
We present a model that relates isotope effects in thermodiffusion to changes in internal
degrees of freedom associated with rotational and vibrational motion. The model uses …

Nonequilibrium thermodynamic material transport equations for thermodiffusion of isotopes and isomers in multicomponent systems

SN Semenov, ME Schimpf - Physical Chemistry Chemical Physics, 2022 - pubs.rsc.org
We extend our nonequilibrium thermodynamic model of thermodiffusion in binary systems to
multi-component mixtures. The fundamental parameter is the difference in molecular entropy …

Statistical Mechanic and Phenomenological Approaches to Isomeric Effects in Thermodiffusion

SN Semenov, ME Schimpf - The Journal of Physical Chemistry B, 2022 - ACS Publications
