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

“这个奖项是根据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)计划将支持爱奥纳学院李成熙教授的研究计划。Lee教授和IONA学院的本科生将学习表面活性剂在液-液界面单分子膜定向结晶中的作用。以含有盐溶液的微滴为模型系统，研究成核过程。这项研究将把模板化能力与表面活性剂单分子膜中的荷电度关联起来；确定碳氢化合物结构变化对成核的影响；考察油相对表面活性剂碳氢链溶剂化成核的影响；研究表面活性剂相变对成核的影响；探索人工双分子层区域在晶体成核和生长中的作用。这项研究将为艾奥纳学院这一研究型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.
