The Environmental Chemical Sciences (ECS) and the Macromolecular, Supramolecular and Nanochemistry (MSN) programs of the Division of Chemistry will support the research program of Prof. Christy Landes of Rice University. Prof. Landes and her research group will develop and apply state of the art single molecule spectroscopic techniques for understanding and controlling transport in charged polymer membranes. The research is thus focused on the water/membrane interface, and will address questions such as how molecules move in charged and crowded environments. The ultimate goal is to be able to predict and control heterogeneous processes in interfacial materials at the molecular scale. The chemical systems to be studied have direct relevance to the heterogeneous phenomena that occur at the environmental water/soil interface. The project will increase our understanding of how molecular-scale dynamics relate to macro-scale interfacial properties. These topics relate to general large-scale issues such as a future shortage of clean energy and water, and more directly to separations and water purification applications. Students working on this project will receive an excellent educational opportunity because it represents an interdisciplinary research project that relates chemistry, physics, materials science and environmental science.

化学系的环境化学科学（ECS）和高分子、超分子和纳米化学（MSN）项目将支持莱斯大学Christy Landes教授的研究项目。兰德斯教授和她的研究小组将开发和应用最先进的单分子光谱技术来理解和控制带电聚合物膜中的传输。因此，该研究的重点是水/膜界面，并将解决分子如何在带电和拥挤的环境中移动等问题。最终目标是能够在分子尺度上预测和控制界面材料的异质过程。 要研究的化学系统与环境水/土壤界面处发生的异质现象直接相关。该项目将加深我们对分子尺度动力学与宏观尺度界面特性之间关系的理解。这些主题涉及一般性的大规模问题，例如未来清洁能源和水的短缺，更直接地涉及分离和水净化应用。 从事该项目的学生将获得极好的教育机会，因为它代表了一个涉及化学、物理、材料科学和环境科学的跨学科研究项目。
