摘要：

The relative effects of nanoparticle motion mechanisms of dilute suspensions, i.e., Brownian motion, thermo-phoresis and osmo-phoresis, including size dependence, on the thermal conductivity were theoretically investigated. The Brownian motion effect was found to be more significant by factors of 0 (106) and 0 (10(8)) when compared to thermo-phoresis and osmo-phoresis, respectively. (c) 2005 Elsevier Ltd.
