PRODEX SoDi: (Selectable Optical DIagnostics). Mesure de coefficient de diffusion et Soret. Prévu à la mi-2007 à bord de la Station Spatiale Internationale [PRODEX SoDi: (Selectable Optical DIagnostics) . Diffusion and Soret coefficient measurement to fly onboard ISS in mid-2007]

qui a été développée en partie grâce au soutien des SSTC dans le cadre d'un programme Prodex. [The SODI facility for the MSG is a 2-wavelength Mach Zehnder Interferometer set-up and a thermal conditioner for liquid cells. It is designed to enable measurements diffusion coefficients in liquid mixtures, primarily crude oils. Thermodiffusion (Soret) coefficients will be measured by applying a thermal gradient to the cell; when relaxing the temperature gradient, one can then also measure isothermal diffusion. The set-up is designed to enable exchange of the cell in the conditioner and thereby, other experiments that can make use of the capabilities. The design will enable to mount the cell conditioner on a system generating low frequency vibrations so as to quantify their influence on the diffusion process (project IVIDIL: Influence of VIbration stimuli on DIffusion in Liquids).]
