Collision Processes and the Kinetic Theory of Polymers, Suspensions and Multicomponent Solutions

John Dahler教授得到理论和计算化学计划的资助，在五个主要领域进行理论研究：1)胶体分散理论；2)小分子流体中的化学反应；3)聚合物相关研究；4)流体中的输运和松弛；5)碰撞理论。他将使用形式化理论并辅以计算机模拟来研究包括聚合物在内的模型流体系统中的传输、松弛和化学反应。由于大多数化学反应发生在液态的溶剂介质中，因此了解溶剂对反应物溶质的影响是非常重要的。在溶质和溶剂之间发生了许多分子相互作用，其中许多可以用连续的分子模型而不是离散的分子模型来模拟。Dahler的研究集中在包括聚合物在内的溶质分子在粘性连续介质中传输的理论模型上。

Professor John Dahler is supported by a grant from the Theoretical and Computational Chemistry Program to perform theoretical studies in five major areas: 1) theory of collodial dispersions; 2) chemical reactions in small molecule fluids; 3) polymer-related research; 4) transport and relaxation in fluids; and 5) topics in collision theory. He will use formal theory supplemented by computer simulations to study transport, relaxation and chemical reactions in model fluid systems including polymers. %%% Since most chemical reactions occur in solvent media in the liquid state, it is of key importance to understand the influence the solvent exerts on the reactant solutes. There are a number of molecular interactions which occur between the solute and the solvent, and many of them can be modeled using a continuum rather than a discrete molecular model for the solvent. Dahler's research focusses on theoretical models for transport of solute molecules, including polymers, in a viscous continuum medium.
