In this award, funded by the Experimental Physical Chemistry Program, Prof. Kenneth B. Eisenthal of Columbia University and his graduate and undergraduate student colleagues will pursue studies aimed at investigating the acid-base reactivity of molecules at interfaces. They will do this by using non-linear spectroscopic methods that are primarily sensitive to molecules at interfaces. The ultimate aim of these studies is to learn how the reactivity of acids and bases changes when the species are present at an interface -- an environment that is quite different from the bulk liquid environment which has heretofore been mostly studied.Acid and base reactivity is a large, ubiquitous class of chemical reactions. Interfaces with liquids are also ubiquitous, e.g. the surface of all bodies of water comprise roughly 2/3 of the earth's surface. It is surprising, but very little is known about the acid-base chemistry that occurs at these types of interfaces. Prof. Eisenthal and his young colleagues are attempting to uncover this important information. Besides the broader scientific impact of these groundbreaking studies, the young scientists supported by this award will receive unparalleled training in interfacial chemistry and physics.

在这个由实验物理化学项目资助的奖项中，哥伦比亚大学的 Kenneth B. Eisenthal 教授及其研究生和本科生同事将开展旨在调查界面分子酸碱反应性的研究。 他们将通过使用主要对界面分子敏感的非线性光谱方法来做到这一点。 这些研究的最终目的是了解当物质存在于界面时，酸和碱的反应性如何变化，界面是一个与迄今为止主要研究的本体液体环境完全不同的环境。酸和碱反应性是一大类普遍存在的化学反应。 与液体的界面也无处不在，例如所有水体的表面约占地球表面的2/3。 令人惊讶的是，但人们对这些类型界面上发生的酸碱化学知之甚少。 艾森塔尔教授和他的年轻同事正试图揭开这一重要信息。 除了这些开创性研究的更广泛的科学影响之外，受该奖项支持的年轻科学家还将接受界面化学和物理学方面无与伦比的培训。
