RUI: Role of Surfactant in Monolayer-Directed Crystallization at the Liquid-Liquid Microdroplet Interface

“这项奖励是根据2009年美国复苏和再投资法案（公法111-5）资助的。”化学系的分析和表面化学（ASC）项目将支持爱奥娜学院Sunghee Lee教授的研究项目。李教授和Iona学院的本科生将研究表面活性剂在液-液界面的单层定向结晶中的作用。含盐溶液的微滴将作为模型系统来研究成核过程。该研究将模板能力与表面活性剂单层的带电程度联系起来；确定烃的结构变化对成核的影响；探讨油相溶剂化对表面活性剂烃链成核的影响；表面活性剂成核后的相变研究并探讨了人工双层面积在晶体成核和生长中的作用。这项研究将为爱奥娜学院的本科生提供良好的培训机会。

"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."The Analytical and Surface Chemistry (ASC) program of the Division of Chemistry will support the research program of Prof. Sunghee Lee of Iona College. Prof. Lee and Iona College undergraduate students will study the role of surfactants in monolayer-directed crystallization at liquid-liquid interfaces. Micro-droplets containing salt solutions will be used as model systems to study the nucleation process. The study will correlate templating ability to degree of charge in surfactant monolayers; determine the influence of the structure of the hydrocarbon change on nucleation; investigate the impact on nucleation of surfactant hydrocarbon chain solvation by the oil phase; study surfactant phase transition upon nucleation; and explore the role of artificial bilayer area in crystal nucleation and growth. The study will provide excellent training opportunities to undergraduate students in Iona College, a Research Undergraduate.
