"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）计划将支持艾奥纳学院的Sunghee Lee教授的研究计划。李教授和艾奥纳学院本科生将研究表面活性剂在液-液界面单分子层定向结晶中的作用。含盐溶液的微液滴将被用作模型系统来研究成核过程。这项研究将模板能力与表面活性剂单层的电荷程度相关联;确定碳氢化合物结构变化对成核的影响;研究油相对表面活性剂碳氢化合物链溶剂化成核的影响;研究成核后的表面活性剂相变;并探索人工双层面积在晶体成核和生长中的作用。这项研究将为艾奥纳学院的本科生提供极好的培训机会。
