Maria Coleman University of Arkansas 9553267 ABSTRACT Research topics include the transport of small molecules through glassy polymer matrices and membrane-based separations for secondary metabolite recovery. The transport studies will focus on modifying the polymer free volume distribution through a combination of synthesis of new polymers and post-synthesis treatments (for example, ion beam irradiation and thermal quenching). This research may lead to improved polymers that act as permselective layers in protective coatings for chemical sensors and membranes for gas separations. Gel forming polymers will be modified with functional groups that exploit protein-metal interactions to obtain membranes which continuously recover secondary metabolites from solution. Membrane-based recovery schemes provide an attractive alternative to commercial chromatography techniques through a reduction in process times and increase in volumetric productivity. Greater student participation and practical applications will be incorporated into the curriculum by modifying the undergraduate laboratories, developing interactive software, and developing an undergraduate research in materials characterization.

Maria Coleman 阿肯色大学 9553267 摘要 研究主题包括小分子通过玻璃状聚合物基质的运输和基于膜的分离以回收次级代谢物。输运研究将侧重于通过新聚合物的合成和合成后处理（例如离子束辐照和热淬火）相结合来改变聚合物自由体积分布。这项研究可能会改进聚合物，作为化学传感器保护涂层和气体分离膜的选择性渗透层。 凝胶形成聚合物将用利用蛋白质-金属相互作用的官能团进行修饰，以获得连续从溶液中回收次级代谢物的膜。 基于膜的回收方案通过减少处理时间和提高体积生产率，为商业色谱技术提供了有吸引力的替代方案。 通过修改本科生实验室、开发交互式软件以及开展材料表征方面的本科生研究，将更多的学生参与和实际应用纳入课程中。
