International Postdoctoral Fellows: A Group Theoretic Approach to the Nonlinear Bifurcation Analysis of Symmetric Shell Structures

9401958米勒该奖项是根据国际初级研究员和博士后研究员计划颁发的，该计划使美国科学家和工程师能够在国外公认的卓越研究中心进行为期3至12个月的研究。该项目的奖项提供了联合研究的机会，并提供了使用国外独特或互补的设施、专业知识和实验条件的机会。该奖项将资助利哈伊大学的克里斯托弗·M·米勒博士为期六个月的博士后研究访问，访问悉尼大学的罗伯特·G·吉尔伯特教授，了解控制细乳液聚合的机理。该项目将应用悉尼大学和利哈伊大学的知识和实验技术，了解支配聚合物形成过程的基础科学，以及所产生的聚合物在微乳液体系中的性质。所获得的知识将为未来使用该工艺进行设计和创新铺平道路。该项目的第一部分将是将悉尼小组报告的新发现纳入先前已有的微乳液动力学模型中。他们的理论涉及自由基进入聚合物颗粒的机制，对解吸的单体自由基命运的详细预测，以及对聚合过程中颗粒生长的时间演化的描述。这些结果将是计算机代码，其预测应该与米勒博士在博士研究期间汇编的典型微乳液聚合的大量数据一致。这项工作的主要目标之一是了解自由基进入单体液滴和聚合物颗粒的机制，因为它们已被证明是不同的。该项目的第二部分将使用悉尼集团可用的Y辐解松弛设施。***

9401958 Miller This award is under the International Junior Investigator and Postdoctoral Fellows Program, which enables U.S. scientists and engineers to conduct three to twelve 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. This award will support a six month postdoctoral research visit by Dr. Christopher M. Miller of Lehigh University to visit Professor Robert G. Gilbert at the University of Sydney on mechanisms controlling miniemulsion polymerization. The project will apply the knowledge and experimental techniques of the University of Sydney and Lehigh to understand the fundamental science of processes governing polymer formation, and properties of the resulting polymer in miniemulsion systems. The knowledge gained will open the way for design and innovation using the process in the future. The first part of the project will be to build into previously existing models for miniemulsion kinetics the new discoveries that were reported by the Sydney group. Their theories concern the mechanisms for radical entry into polymer particles, detailed predictions of the fate of desorbed monomeric radicals, and a description of the time evolution of particle growth during the polymerization. The outcome of these will will be computer codes whose predictions should be consistent with the extensive data for archetypical miniemulsion polymerizations compiled by the Dr. Miller during the course of his doctoral studies. On of the main goals of this work is to understand the mechanisms governing radical entry into monomer droplets and polymer particles, since these have shown to be different. The second part of the project will be to use the Y radiolysis relaxation facilities available to the Sydney group. ***
