In this project, funded by the Experimental Physical Chemistry Program of the Chemistry Division, Prof. Gilbert Nathanson of the University of Wisconsin-Madison will conduct a research program to study collisions and reactions of reactive gases with pure and salty protic solvents, molten alkali hydroxides, and organic ionic liquids. The work has four specific goals: 1) To explore interfacial reactions through observations of gas-liquid deuterium to hydrogen exchange; 2) to investigate the catalyzation or suppression of interfacial reactions by ions dissolved at the surfaces of salty liquids; 3) to map out the pathways for scattering, trapping, acid-base, and oxidation-reduction reactions in collisions of protic gases with molten alkali hydroxides; and 4) to investigate how gas-liquid energy transfer and reaction rates are influenced by the alkyl chain structure of organic ionic liquids. These studies will contribute to the development of a molecular picture of gas-liquid interfaces, which will promote the understanding of gas-liquid processes occurring industrially and in the atmosphere.Graduate and undergraduate students, including women and underrepresented minorities, will participate in this research.

在这个由化学系实验物理化学计划资助的项目中，威斯康星大学麦迪逊分校的吉尔伯特·内桑森教授将进行一项研究计划，研究反应性气体与纯的和含盐的质子溶剂、熔融碱金属氢氧化物和有机离子液体的碰撞和反应。 本工作有四个具体目标：1）通过观察氘-氢交换来探索界面反应; 2）研究溶解在含盐液体表面的离子对界面反应的催化或抑制作用; 3）绘制质子气体与熔融碱金属氢氧化物碰撞中散射、俘获、酸碱和氧化还原反应的路径;研究有机离子液体的烷基链结构对气液能量传递和反应速率的影响。 这些研究将有助于发展气液界面的分子图像，从而促进对工业和大气中发生的气液过程的了解，研究生和本科生，包括妇女和代表人数不足的少数民族，将参加这项研究。
