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. ***

Barrall该奖项是国际青年研究员和博士后研究员计划的一部分，它使美国科学家和工程师能够在国外被证明卓越的研究中心进行三到二十四个月的研究。该计划的奖励为联合研究提供了机会，并利用独特或互补的设施、专业知识和国外的实验条件。该奖项的财政支持来自美国-新西兰项目。该奖项将支持Geoffrey a . Barrall博士前往新西兰北部的Palmerston进行为期12个月的博士后研究访问，与梅西大学的Paul Callaghan博士一起工作。本研究将重点发展和使用脉冲梯度自旋回波（PGSE）核磁共振（NMR）技术来研究高分子量聚合物在流动和非流动体系中的平移动力学。这些研究的主要目的是利用核磁共振技术提供的新的实验信息来测试现有聚合物动力学理论的预测。这项研究将对美国塑料工业使用的工程工艺有很大的适用性。＊＊＊
