The Environmental Chemical sciences (ECS) program of the Division of Chemistry will support the research program of Prof. Franz Geiger of Northwestern University. Prof. Geiger's research program focuses on the application for the first time of a unique spectroscopic method, named the Eisenthal chi(3) method, to study the adsorption of metal cations on mineral surfaces. The Eisenthal chi(3)method is uniquely sensitive to the interfacial potential and can be viewed as an Optical Voltmeter. If successful, the study will provide environmental scientists with a new and widely applicable tool for studying ion adsorption on mineral surfaces. The project has the potential to transform our understanding of interfacial phenomena in complex environmental systems. The project will provide excellent educational opportunities for trainees desiring to work at the forefront of environmental science.

化学系的环境化学科学（ECS）计划将支持西北大学Franz盖革教授的研究计划。盖革教授的研究项目集中在一个独特的光谱方法，命名为艾森塔尔chi（3）方法的第一次应用，研究金属阳离子在矿物表面的吸附。Eisenthal chi（3）方法对界面电位非常敏感，可以看作是一种光学伏特计。如果成功，该研究将为环境科学家提供一种新的和广泛适用的工具，用于研究矿物表面的离子吸附。该项目有可能改变我们对复杂环境系统中界面现象的理解。该项目将为希望在环境科学前沿工作的学员提供极好的教育机会。
