Collisions and Reactions at the Surfaces of Cold Salty Water and Hot Ionic Liquids

在这个由化学系实验物理化学项目资助的项目中，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项目，研究气体在冷咸水和热碱性碳酸盐表面的碰撞和反应。这项研究的长期目标是通过探索碰撞能量转移、体溶剂化、氢键、类似溶解相似规则以及酸碱和氧化还原反应等界面模拟来绘制气液界面的分子图像。本工作有三个具体目标：1)研究氯化氢气体在水中的界面解离以及溶解离子如何促进或抑制这种常见酸的解离；2)探索放热的气液反应，如卤素原子交换F2(G)+I-=F-+IF(G)，它可能导致IF产物非热喷射到气相中；3)了解熔融的碳酸盐溶液如何捕获二氧化硫气体，以便对燃煤电厂的烟气脱硫进行模拟。研究生和本科生，包括女性和男性，都将参与这项研究。

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 gases at the surfaces of cold salty water and hot alkali carbonates. The long-term objective of this research is to develop a molecular picture of gas-liquid interfaces by exploring the interfacial analogues of collisional energy transfer, bulk solvation, hydrogen bonding, the "like dissolves like" rule, and acid-base and oxidation-reduction reactions. The present work has three specific goals: 1) to investigate the interfacial dissociation of hydrogen chloride gas in water and the ways in which dissolved ions enhance or suppress dissociation of this common acid; 2) to explore exothermic gas-liquid reactions, such as the halogen atom exchange F2(g) + I- = F- + IF(g), which may lead to non-thermal ejection of the IF product into the gas phase, and 3) to learn how molten carbonate solutions capture sulfur dioxide gas in order to model flue gas desulfurization in coal-burning power plants. Graduate and undergraduate students, both women and men, will participate in this research.
