Second Harmonic Studies of Liquid Interfaces

哥伦比亚大学化学系的Kenneth B.Eisenthal博士获得了美国国家科学基金会化学部实验物理化学项目的支持，他的工作是利用二次谐波产生(SHG)技术来探测分子在双分子层中的传输过程中的界面动力学，如分子在双分子层中的组成、双分子层中的分子取向、溶剂化动力学和跨双层膜的电荷转移。这些研究将产生很大的影响，并为分子跨膜运输提供新的见解，这将对医学界(例如，在药物输送问题上)、生化和生物界以及物理化学界在超快飞秒现象方面产生重大影响。学生和博士后将接受包括化学、生物和生物化学在内的独特领域的培训。

Dr. Kenneth B. Eisenthal of the Department of Chemistry, Columbia University, is supported by the Experimental Physical Chemistry program of the Division of Chemistry, National Science Foundation, for his work on the utilization of the Second Harmonic Generation (SHG) technique to probe interfacial dynamics in such processes as molecular transport through bilayers as a function of composition, molecular orientation in bilayers, solvation dynamics and charge transfer across a bilayer membrane. These studies will have a high impact and provide new insights into transport of molecules across membranes that will have a great impact to the medical community (for example, in drug delivery issues), to the biochemical and biology communities, and to the physical chemistry community with regard to ultrafast femtosecond phenomena. Students and post-doctoral associates will be trained in a unique area that encompasses chemistry, biology, and biochemistry.
