The Analytical and Surface Chemistry Program at NSF Division of Chemistry will support the international collaborative research project of Prof. Peter Lu of Bowling Green State University and Prof. Alfred Meixner of Eberhar-Karls University of Tubingen, Germany. Profs. Lu and Meixner, and their students will focus their study on characterizing the processes of dye-TiO2 surface chemical bonding, vibronic coupling, and interfacial electron transfer (IET) associated with vibrational relaxation energy barriers. The project will adavance fundamental understanding of the spatially heterogenous energetics that regulates IET processes. The collaborative study will result in a new and improved spectroscopic method with the capability to interrogate in real time the dynamic relationship between the interface structure and energy when IET occurs. The advanced knowledge and technology developed in this project will significantly impact the thinking of condensed-phase physical and chemical dynamics and ultimately enhance research on new energy sciences. The international collaboration between the US and German research groups will provide excellent training opportunities and invaluable international experience to students participating in this research project.This international collaborative research project is supported jointly by NSF and the Deutsche Forschungsgemeinschaft (DFG) of Germany. The study is also supported by the Office of International Science and Engineering (OISE) at NSF.

NSF化学部的分析和表面化学计划将支持鲍林格林州立大学的Peter Lu教授和德国图宾根Eberhar-Karls大学的Alfred Meixner教授的国际合作研究项目。教授们。Lu和Meixner以及他们的学生将专注于表征染料-二氧化钛表面化学键、振动耦合和与振动弛豫势垒相关的界面电子转移(IET)过程。该项目将有助于从根本上理解控制IET过程的空间异质能量学。这项合作研究将产生一种新的和改进的光谱方法，能够实时询问IET发生时界面结构和能量之间的动态关系。该项目开发的先进知识和技术将对凝聚相物理化学动力学的思维产生重大影响，并最终加强对新能源科学的研究。美国和德国研究小组之间的国际合作将为参与这一研究项目的学生提供极好的培训机会和宝贵的国际经验。这一国际合作研究项目由NSF和德国联邦科学基金会(DFG)联合支持。这项研究也得到了美国国家科学基金会国际科学与工程办公室(OISE)的支持。
