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.

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教授和她的学生旨在确定由简单和复杂的流体形成的固体融合界面中的界面分子结构，并阐明了界面流体动力学特性对该分子结构的依赖性。对固体界面的控制需要对控制这些接口的静态和动态特性的分子结构 - 功能关系的理解。尽管界面流体动力学的理论框架是手头的，并且最近的计算和理论努力已经详细地预测了界面流体动力学行为，但实验研究定义了界面分子结构并与界面动力学特性相关。在这项工作中，将使用光学光谱研究研究表面化学和形态，界面分子组织和结构在模板上，独特的界面流体结构，并与界面动力学相关。这些研究还将扩展到包括聚合物在内的复杂液体。界面内部和垂直方向的动态特性改变的影响也将被研究，将与与界面内分子纠缠有关的效果。这项高度跨学科的努力是将其化学研究直接相关的学生作为肥沃的培训地面，因为他们的化学研究直接相关是流动性化学物质，机械性工程学，生物学科学，生物学科学，以及生物学科学，以及生物技术。这项工作的结果将在这些不同社区经常光顾的场所中广泛传播。由于这项工作奠定了对流体特性更深入的分子理解的基础，因此该项目的博士后研究人员和研究生将与当地高中化学老师一起工作至少一个学期，以开发适用于常规高中化学和高中高中化学水平的流体的分子结构和动态性能的入门模块。
