Role of thermophoresis on unsteady/steady mixed convective

MST is based on the quantifiable detection of a fluorescence change in a sample when a temperature change is applied. The fluorescence of a target molecule can be extrinsic or intrinsic (aromatic amino acids) and is altered in temperature gradients due to two distinct effects. On the one hand temperature related intensity change (TRIC), which describes the intrinsic property of fluorophores to change their fluorescence intensity as a function of temperature. The extent of th… Webb29 mars 2007 · It is found that thermophoresis due to surface forces is insensitive to hydrodynamic interactions, and the thermal diffusion coefficient D(T) of polymer solutions is independent of molecular weight and concentration.
