| dc.description.abstractEn | We report on the first microscale observation of the velocity field imposed by a nonuniform heat content along the solid-liquid boundary.We determine both radial and vertical velocity components of this thermoosmotic flow field by tracking single tracer nanoparticles. The measured flow profiles are compared to an approximate analytical theory and to numerical calculations. From the measured slip velocity we deduce the thermo-osmotic coefficient for both bare glass and Pluronic F-127 covered surfaces. The value for Pluronic F-127 agrees well with Soret data for polyethylene glycol, whereas that for glass differs from literature values and indicates the complex boundary layer thermodynamics of glass-water interfaces. | |
