U.S.-Brazil Planning Visit: Photophysical Studies in Polymers

9906013 Weiss这个美国-巴西奖支持Richard G.Weiss博士和华盛顿乔治城大学的两名学生计划访问坎皮纳斯大学的Teresa Atvars博士和巴西里约热内卢联邦大学的Ira Brinn教授，开发合作研究项目，涉及使用荧光技术探索聚合物的性质，以及测定2-羟基苯基拉巴唑中光诱导分子内质子转移的类型和速率。Atvars教授是聚合物物理过程方面的公认专家，Brinn博士的实验室拥有最先进的闪光光解设备，可以轻松地进行改装，以研究聚合物薄膜中客体的瞬时物种。Weiss博士的亲自到场将使设备改进得以概念化，并使所有各方都满意。此外，在计划访问期间，PI和学生将利用乔治敦大学没有的设备进行一些初步实验，以消除因缺乏直接观察而产生的歧义。。它将验证两个实验室的学生/博士后是否将使用相同的科学语言进行交流。***

9906013WeissThis U.S.-Brazil award supports a planning visit by Dr. Richard G. Weiss and two students of Georgetown University, Washington D.C., to meet with Dr. Teresa Atvars at the Universidada Estadual de Campinas and Professor Ira Brinn at Universidade Federal de Rio de Janeiro, Brazil, to develop collaborative research projects concerning the exploration of polymer properties using fluorescence techniques and the determination of the types and rates of photoinduced intramolecular proton transfer in 2-hydroxyphenyl-lapazole.Professor Atvars is a recognized expert in physical processes in polymers and Dr. Brinn's laboratory posses a state-of-the-art flash photolysis apparatus that could be modified easily to investigate transient species from guests in polymer films. The in-person presence of Dr. Weiss will allow equipment modification to be conceptualized and carried out to the satisfaction of all parities. Additionally, during the planning visit the PI and students will utilize equipment not available at Georgetown to conduct some preliminary experiments in order to remove ambiguities that accompany a lack of direct observation. . It will verify that the students/post docs from the two labs will be communicating in the same scientific language. ***
