"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.

“该奖项是根据2009年的《美国回收与再投资法》（公法111-5）资助的。”化学司的分析和表面化学计划（ASC）计划将支持Iona学院的Sunghee Lee教授的研究计划。李教授和爱奥娜学院的本科生将研究表面活性剂在液体液体界面上单层定向结晶中的作用。含有盐溶液的微滴滴将用作研究成核过程的模型系统。该研究将使模板能力与表面活性剂单层中的充电程度相关联；确定碳氢化合物变化对成核的影响；研究对石油相对表面活性剂烃链溶剂化溶剂成核的影响；成核时研究表面活性剂相变；并探索人造双层区域在晶体成核和生长中的作用。这项研究将为本科生爱奥娜学院的本科生提供极好的培训机会。
