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 the hot rod of an electric heater is surrounded by tobacco smoke: the smoke goes away from the immediate vicinity of the hot rod. As the small particles of air … 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 1882. Thermophoresis in liquid mixtures … Visa mer • A short introduction to thermophoresis, including helpful animated graphics, is at aerosols.wustl.edu • Thermophoresis of DNA in an aqueous solution Visa mer The thermophoretic force has a number of practical applications. The basis for applications is that, because different particle types move differently under the force of the temperature gradient, the particle types can be separated by that force after they've … Visa mer • Microscale thermophoresis • Deposition (aerosol physics) • Dufour effect Visa mer WebbTrapping of Single Nano-Objects in Dynamic Temperature Fields Marco Braun11{}^{1}start_FLOATSUPERSCRIPT 1 end_FLOATSUPERSCRIPT, Alois Würger22{}^{2}start_FLOATSUPERSCRIPT 2 end_F
