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.

摘要提案编号：CTS-0201131首席研究员：Blawzdziewics和Walz隶属于：耶鲁大学标题：不对称胶体混合物中的粒子动力学该提案是为混合物中的大胶体粒子的动力学发展一个“马尔可夫”简化描述。 这种方法是基于分离的时间尺度表征的粒子和周围的大分子的运动。 通过这种方法，考虑到粒子的演化由广义Smoluchowski方程控制，大分子的作用将被耗尽势和有效迁移率张量捕获，后者对粒子分离和离壁的距离具有非平凡的依赖性。
