TL;DR: In this article, the authors report on thermodiffusion experiments conducted on the International Space Station ISS during fall 2016, where the SODI instrument and the DCMIX experiments have proven reliable and robust, allowing to extract meaningful data even in case of unforeseen laser instabilities.

TL;DR: The experiments devoted to study thermodiffusion of fluid mixtures in microgravity environment, where sedimentation and convection do not affect the mass flow induced by the Soret effect are described.

TL;DR: In this paper, measurements of diffusion, thermodiffusion, and Soret coefficients in binary pairs of the ternary system toluene-methanol-cyclohexane using different instrumental techniques: SODI/DCMIX2, thermogravitational column in combination with sliding symmetric tubes, optical beam deflection, optical digital interferometry, and counter flow cell.

TL;DR: A decrease of the thermodiffusion coefficient with increasing ratio of the thermal expansion coefficient and viscosity for a binary mixture of an organic ring compound with a short n-alkane is reported.

TL;DR: In this article, the authors measured the thermodiffusion coefficients by means of density analysis using the thermogravitational column technique from 5 wt % to 50 Wt % at 25∘C.
