In this award, supported by the Experimental Physical Chemistry Program of the Chemistry Division, Prof. Sandra Greer of the University of Maryland, College Park will conduct research studying complex nanostructures and phase transitions in aqueous polymer solutions. The samples will be studied with viscometry, size-exclusion chromatography, small-angle neutron scattering and dynamic light-scattering techniques. The ultimate goal of the research is to develop a deeper understanding of the underlying mechanisms for the behaviors of aqueous polymer systems. Ultimately, the research may result in useful ways of improving the control of polymer molecular weight, as well as having eventual applications in nanotechnology and biomimetic systems. The proposed research will be carried out by undergraduate, graduate and post-doctoral researchers, working with Prof. Greer.

在该奖项中，由化学部实验物理化学计划支持，马里兰州大学帕克分校的Sandra Greer教授将进行研究，研究聚合物水溶液中的复杂纳米结构和相变。 将用粘度法、尺寸排阻色谱法、小角中子散射和动态光散射技术对样品进行研究。 研究的最终目标是对含水聚合物体系行为的潜在机制有更深入的了解。 最终，这项研究可能会导致改善聚合物分子量控制的有用方法，并最终应用于纳米技术和仿生系统。 拟议的研究将由本科生，研究生和博士后研究人员与Greer教授合作进行。
