Correlation of Molecular Architecture and Fluid Dynamic Properties within Solid-Fluid Interfaces

分析和表面化学计划支持亚利桑那大学珍妮·彭伯顿教授的研究计划。Pemberton教授和她的学生的目标是确定由简单和复杂流体形成的固液界面的界面分子结构，并阐明界面流体动力学性质对该分子结构的依赖关系。固体-流体界面的控制需要发展对控制这些界面的静态和动态性质的分子结构-功能关系的理解。尽管界面流体动力学的理论框架已经形成，最近的计算和理论工作已经相当详细地预测了界面流体的动力学行为，但定义界面分子结构并与界面动力学性质相关联的实验研究很少。在这项工作中，表面化学和形态以及界面分子的组织和结构在模板中的作用，独特的界面流体结构将利用光学光谱进行研究，并与界面动力学相关联。这些研究还将扩展到复杂的流体，包括聚合物。还将研究界面内横向和垂直方向动态性质改变的影响，以及与界面内分子纠缠有关的影响。这一高度跨学科的努力为学生提供了一个肥沃的训练场，他们将看到他们在流体物理、机械工程、生物分析和生物技术以及环境科学等不同领域的化学研究的直接相关性。这项工作的结果将在这些不同社区经常光顾的场所以口头和书面形式广泛传播。由于这项工作为加深对流体性质的分子理解奠定了基础，该项目的博士后研究人员和研究生将至少花一个学期的时间与当地高中化学教师合作，开发适合普通高中化学和高中高等化学水平的流体分子结构和动力学性质的入门模块。

The Analytical and Surface Chemistry Program supports the research program of Prof. Jeanne Pemberton at the University of Arizona. Prof. Pemberton and her students aim to determine the interfacial molecular structure in solid-fluid interfaces formed with simple and complex fluids and elucidate the dependence of interfacial fluid dynamic properties on that molecular structure. Control of solid-fluid interfaces necessitates development of an understanding of molecular structure-function relationships that govern the static and dynamic properties of these interfaces. Although the theoretical framework for interfacial fluid dynamics is in hand and recent computational and theoretical efforts have predicted interfacial fluid dynamic behavior in considerable detail, experimental investigations in which interfacial molecular structure is defined and correlated with interfacial dynamic properties are sparse. In this work, the role of surface chemistry and morphology, and interfacial molecular organization and structure in templating, unique interfacial fluid structure will be studied using optical spectroscopies and correlated with interfacial dynamics. These studies will also be extended to complex fluids, including polymers. Effects of altered dynamic properties within the interface in both the lateral and vertical directions will also be studied as will effects related to the entanglement of molecules within the interface.This highly interdisciplinary effort serves as a fertile training ground for students who will see the direct relevance of their chemical research in areas as diverse as fluid physics, mechanical engineering, bioanalysis and biotechnology, and environmental science. Results of this work will be broadly disseminated, both orally and in writing, in venues frequented by these diverse communities. Since this work lays the foundation for a deeper molecular understanding of fluid properties, postdoctoral researchers and graduate students on this project will spend at least one semester working with local high school chemistry teachers to develop introductory modules on the molecular structure and dynamic properties of fluids appropriate for the regular high school chemistry and high school Advanced Placement chemistry levels.
