International Postdoctoral Fellows Program: Nuclear Magnetic Resonance Studies of High Polymer Molecular Dynamics and Rheology

小行星9504552 该奖项是根据国际初级研究员和博士后研究员计划，使美国科学家和工程师能够在国外进行三到二十四个月的研究，在证明卓越的研究中心。该计划的奖项提供了联合研究的机会，以及使用国外独特或互补的设施，专业知识和实验条件。 该奖项的财政支持来自美国-新西兰计划。 该奖项将支持杰弗里·A博士为期12个月的博士后研究访问。Barrall将前往新西兰北部的帕默斯顿，与梅西大学的Paul Callaghan博士一起工作。 本研究将侧重于脉冲梯度自旋回波（PGSE）核磁共振（NMR）技术的开发和使用，以研究高分子量聚合物在流动和非流动系统中的平移动力学。 这些研究的主要目标是测试目前的聚合物动力学理论的预测使用新的实验信息提供的NMR技术。 这项研究将有很大的适用性，美国塑料工业所使用的工程过程。***

9504552 Barrall This award is under the International Junior Investigator and Postdoctoral Fellows Program, which enables U.S. scientists and engineers to conduct three to twenty-four months of research abroad at research centers of proven excellence. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad. Financial support for this award is from the U.S.-New Zealand Program. This award will support a twelve-month postdoctoral research visit by Dr. Geoffrey A. Barrall to go to Palmerston, North, New Zealand to work with Dr. Paul Callaghan of Massey University. This research will focus on the development and use of pulsed gradient spin echo (PGSE) nuclear magnetic resonance (NMR) techniques to study the translational dynamics of high molecular weight polymers in flowing and non-flowing systems. The primary goal of these studies is to test the predictions of present polymer dynamics theories using new experimental information provided by NMR techniques. This research will have great applicability to engineering processes used by the American plastics industries. ***
