Transport Phenomena in Particle Suspensions: Sedimentation and Thermophoresis

摘要

This chapter deals with transport phenomena induced in colloidal suspensions and complex fluids either by gravity, which is the well established but nevertheless still stimulating subject of sedimentation, or by thermophoresis, a subtler and very intriguing effect that is still partly understood. Specifically, I shall highlight the wealth of information one can get by investigating the particle concentration profiles generated at equilibrium by sedimentation, or at steady-state by thermophoresis, and discuss some novel optical techniques that have been fruitfully exploited to study them.
