Phonon Thermophoresis of Crystalline Nanoparticles in Liquids (Semen N. Semenov and Martin E. Schimpf) Physcial Chemistry Chemical Physics (2024)

Our nonequilibrium thermodynamic model of thermodiffusion in molecular liquid systems is used to examine the role of thermal phonons in the thermophoresis of liquid suspensions of crystalline nanoparticles, which tend to have high thermal conductivity. ...

Statistical Mechanic and Phenomenological Approaches to Isomeric Effects in Thermodiffusion (Semen N. Semenov and Martin E. Schimpf) The Journal of Physical Chemistry B (2022)
