The Experimental Physical Chemistry Program of the Division of Chemistry, National Science Foundation, supports the work of Prof. George W. Flynn, Department of Chemistry, Columbia University, for his work on elucidating the factors that control self-assembly, molecular structure, and functional group conformation in chiral and achiral molecular films physisorbed at liquid-solid interfaces. A rather unique Scanning Tunneling Microscopy approach will be developed and used to determine chemical structure and dynamics at these interfaces.The results of the study will be of fundamental interest and of practical importance in the design of self-assembled interfaces. The observation, control and manipulation of these interfaces will be significant in the development of next generation microscopic optical and electronic devices, chemical sensors, and biomedical monitors that function on the nanoscale dimension. Undergraduate and graduate students, and post-doctoral associates will acquire considerable experience and skills in a variety of physical methods in the developing field of Nanoscience and Nanotechnology.

美国国家科学基金会化学部实验物理化学计划支持乔治W.弗林，化学系，哥伦比亚大学，他的工作阐明了控制自组装的因素，分子结构，以及在液-固界面物理吸附的手性和非手性分子膜中的官能团构象。一种独特的扫描隧道显微镜方法将被开发并用于确定这些界面处的化学结构和动力学，研究结果将在自组装界面的设计中具有基本的兴趣和实际意义。这些接口的观察，控制和操纵将是重要的下一代微观光学和电子器件，化学传感器和生物医学监测器，功能在纳米尺度上的发展。本科生和研究生以及博士后助理将在纳米科学和纳米技术的发展领域的各种物理方法中获得相当多的经验和技能。
