项目摘要

The Environmental Chemical Sciences (ECS) program of the Division of Chemistry will support the research program of Prof. Geraldine Richmond of the University of Oregon. Prof. Richmond and her research group will employ non-linear optical methods in combination with supporting particle size and zeta potential measurements and molecular dynamic simulations to is to provide molecular level insights into absorptive and reactive processes at the interface of aqueous solutions in contact with oils, gases, and macromolecular systems. The studies focus on: i) understanding the behavior of surfactants, polymers and dispersants at planar and particle interfaces between water and an organic liquid (oil); and ii) understanding the adsorption, solvation and reactivity of gases and small organic molecules on the surface of aqueous solutions. Molecular level understanding of the water/oil interface will enable better assessment and prediction of environmental damage due to oil spills like the 2010 Deep Horizon oil spill in the Gulf of Mexico. The study will provide excellent training opportunities to students and postgraduates who seek training in the area of environmental interface chemistry. Prof. Richmond and her students will carry out extensive outreach activities to explain the importance of their research to the general public and continue their on-going activities to broaden participation of women and minorities in science.

化学系的环境化学科学(ECS)计划将支持俄勒冈大学杰拉尔丁·里士满教授的研究计划。Richmond教授和她的研究小组将使用非线性光学方法，结合支持的颗粒大小和Zeta电位测量以及分子动力学模拟，在分子水平上深入了解水溶液与油、气体和高分子体系接触时的界面吸收和反应过程。这些研究的重点是：i)了解表面活性剂、聚合物和分散剂在水和有机液体(油)之间的平面和颗粒界面上的行为；以及ii)了解气体和有机小分子在水溶液表面的吸附、溶剂化和反应活性。对水/油界面的分子水平了解将有助于更好地评估和预测因2010年墨西哥湾深水地平线漏油事件等漏油事件造成的环境损害。这项研究将为寻求环境界面化学领域培训的学生和研究生提供极好的培训机会。里士满教授和她的学生将开展广泛的外展活动，向公众解释他们研究的重要性，并继续他们正在进行的活动，以扩大妇女和少数族裔对科学的参与。
