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.

化学学部的大分子、超分子和纳米化学（MSN）项目和工程理事会的GOALI项目将支持蒙大拿大学爱德华·罗森伯格教授的研究项目。Rosenberg教授和他的学生与当地一家公司Purity systems Inc.合作开发了一种新型无定形硅聚合物复合材料，这种材料正在商业化生产，并被用于采矿和修复行业。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颗粒，并将其用作金属阳离子的发光探针。这些粒子的发光响应是基于硅多胺复合纳米粒子的发光硅核与表面结合的钌配合物之间的共振能量转移（RET）。发光粒子将被纳入水过滤膜，并用于监测金属结合这些膜时，放置在污染的水样。二氧化硅多胺复合纳米颗粒也将用于多相加氢反应的新型催化剂。这种新型发光纳米材料将广泛应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。该研究项目将为复合材料领域的学生提供良好的培训机会，他们寻求在工业领域的研究和开发事业。罗森博格教授将让本科生和研究生，包括美国原住民学生参与拟议的研究。
