Theory of the soret effect

WebbSoret effect and Dufour effect represent the coupled phenomena between the vectorial flows of heat and mass. Since many chemical reactions within a biological cell produce or consume heat, local temperature gradients may contribute in the transport of materials across biomembranes. The term Soret effect normally applies to liquid mixtures, which behave according to different, less well-understood mechanisms than gaseous mixtures. Thermophoresis may not apply to thermomigration in solids, especially multi-phase alloys. Visa mer Thermophoresis (also thermomigration, thermodiffusion, the Soret effect, or the Ludwig–Soret effect) is a phenomenon observed in mixtures of mobile particles where the different particle types exhibit different responses … Visa mer Thermophoresis in gas mixtures was first observed and reported by John Tyndall in 1870 and further understood by John Strutt (Baron Rayleigh) in … Visa mer • A short introduction to thermophoresis, including helpful animated graphics, is at aerosols.wustl.edu • Thermophoresis of DNA in an aqueous solution on YouTube Visa mer The phenomenon is observed at the scale of one millimeter or less. An example that may be observed by the naked eye with good lighting is when … Visa mer The thermophoretic force has a number of practical applications. The basis for applications is that, because different particle types move … Visa mer • Microscale thermophoresis • Deposition (aerosol physics) • Dufour effect Visa mer
