ABSTRACTProposal Number: CTS-0201131Principal Investigator: Blawzdziewics and WalzAffiliation: Yale UTitle: Particle Dynamics in Asymmetric Colloidal MixturesThe proposal is to develop a 'Markovian' reduced description for the dynamics of large colloidal particles in a mixture. This approach is based on the separation of the time scales characterizing the motion of the particles and the surrounding macromolecules. With this approach, considering that the evolution of the particles is governed by a generalized Smoluchowski equation, the effect of the macromolecules will be captured by depletion potential and the effective mobility tensor, the later having a nontrivial dependence on particle separation and the distance from the wall.
