Thermal Probes of Nanoparticle Interfaces: Thermodiffusion and Thermal Conductivity of Nanoparticle Suspensions
Abstract
dc:descriptionAt T < 20°C, all nanoparticles studied in nearly pure water were found to migrate to the hot regions of the fluid; i.e., DT 50°C, the thermodiffusion coefficients were positive with a value consistent with the predictions of a theoretical model originally proposed by B. Derjaguin that is based on the enthalpy changes due to polarization of water molecules in the double-layer. At high temperatures, DT was also independent of particle size.
