GOALI-Silica Polyamine Composites: Hybrid Materials for Nanotechnology and Catalysis

化学部的大分子，超分子和纳米化学（MSN）计划和工程理事会的GOALI计划，并将支持蒙大拿大学爱德华·罗森伯格教授的研究计划。罗森伯格教授和他的学生，在与当地公司，纯度系统公司合作。已经开发了一类新型的无定形二氧化硅-聚合物复合材料，其正在商业化生产并用于采矿和修复工业。在这个项目中，Rosenberg教授和他的学生将合成发光二氧化硅多胺复合纳米粒子，并将其用作金属阳离子的发光探针。 这些颗粒的发光响应是基于二氧化硅多胺复合纳米颗粒的发光硅核与表面结合的钌络合物之间的共振能量转移（RET）。发光颗粒将被并入到水过滤膜中，并且当被放置在受污染的水样中时，用于监测与这些膜结合的金属。 二氧化硅多胺复合纳米粒子也将被用于非均相加氢反应的新型催化剂。新型发光纳米材料将广泛用于饮用水净化和废水处理等关键环境应用。 这项技术的商业化将对采矿和金属加工业产生重大影响。 该研究计划将为寻求工业研究和开发职业的复合材料领域的学生提供良好的培训机会。罗森伯格教授将涉及本科生和研究生，包括美洲原住民学生在拟议的研究。

The Macromolecular, Supramolecular and Nanochemistry (MSN) program in the Division of Chemistry and the GOALI program of the Engineering Directorate and will support the research program of Prof. Edward Rosenberg of the University of Montana. Prof. Rosenberg and his students, in collaboration with a local company, Purity systems Inc. has developed a novel class of amorphous silica-polymer composite materials that are being commercially produced and are being used in the mining and remediation industries. In this project, Prof. Rosenberg and his students will synthesize luminescent silica polyamine composite nanoparticles and use them as luminescent probes for metal cations. The luminescence response of these particles is based on resonance energy transfer (RET) between the luminescent silicon core of the silica polyamine composite nanoparticles and surface bound ruthenium complexes. The luminescent particles will be incorporated incorporate into water filtration membranes and used to monitor metal binding to these membranes when placed in contaminated water samples. Silica polyamine composite nanoparticles will also be used novel catalysts in heterogeneous hydrogenation reactions. The new class of luminescent nanomaterials will be used widely in critical environmental applications like drinking water purification and waste water treatment. Commercialization of this technology will have a significant impact on the mining and metal processing industry. The research program will provide excellent training opportunities to students in the area of composite materials who seek research and development careers in industry. Prof. Rosenberg will involve undergraduate and graduate students, including Native American students in the proposed research.
