Theoretical Investigations of Densification Kinetics in Adsorption and Granular Materials

Julian Talbot得到了理论和计算化学计划的资助，对两个具体问题进行理论研究：1)从溶液中吸附蛋白质等大分子；2)颗粒材料的压实。这些问题的理论方法包括计算格子模拟技术和随机顺序吸附理论。颗粒压实在食品、谷物、化学品和药品的生产、包装和运输中非常重要。蛋白质吸附是许多工业和生物医学应用的关键步骤。尽管如此，吸收和压实的动力学，特别是混合物的吸收和压实动力学，目前还知之甚少。所提出的工作将促进我们对这些重要系统的动力学的基本理解。

Julian Talbot is supported by a grant from the Theoretical and Computational Chemistry Program to perform theoretical studies of two specific problems: 1) the adsorption of macromolecules such as proteins from solution; and 2) the compaction of granular materials. The theoretical approach to these problems involves computational lattice simulation techniques and the theory of random sequential adsorption. Granular compaction is important in the production, packing and transportation of foods, grains, chemicals and drugs. Protein adsorption is a key step in many industrial and biomedical applications. In spite of this the kinetics of absorption and compaction, particularly of mixtures, is poorly understood at the present time. The proposed work will advance our fundamental understanding of the kinetics of these important systems.
