National Science Foundation - Division of Chemical &Transport Systems Particulate & Multiphase Processes Program (1415)ABSTRACTProposal Number: 0642328Principal Investigator: Codd, Sarah L.Affiliation: Montana State UniversityProposal Title: CAREER: Engineering Applications of magnetic Resonance Microscopy (MRM) to Porous Media Structure and TransportIntellectual MeritMagnetic resonance microscopy (MRM) can investigate flow, diffusion, and spatial variations in matter on spatial scales of the order of 10 m (spatially resolved) or 10 nm (bulk measurements of molecular motion) and over timescales ranging from 10 s to 1s. Porous material structures to be studied will range from the hydrogel extra-cellular polymeric substance (EPS) of biofilms, to membranes, to novel advanced ceramics and model porous beadpacks. Studies will measure active nuclei concentration, velocity, diffusion and magnetic relaxation within these materials, characterizing structure through porosity and tortuosity, as well as quantifying transport. The research plan allows for the continuation and expansion of a current program in biofilms and membranes and the initiation and growth of research in ceramics and polymer transport in porous media, whilst expanding on integration with teaching activities. Broader ImpactsRich interdisciplinary research experiences will be provided for graduate students in a blossoming career field. A graduate and professional undergraduate elective course entitled Ways for engineers to see non-destructive visualization for materials science" will be developed and a portable Earths Field Magnetic resonance imaging (MRI) apparatus will be integrated into undergraduate and outreach programs. The overall program will aim to provide unique insight regarding the physics of societally important materials at the forefront of current materials science development. Integration with education aims to increase students' and the broader community's awareness of the interdisciplinary nature of materials science research and exciting research applications demonstrate the necessity of engineering education to further advancements for society.

国家科学基金会-化学与运输系统颗粒与多相过程部门计划(1415年)摘要建议编号：0642328主要研究员：Codd，Sarah L.隶属：蒙大拿州立大学建议标题：职业：磁共振显微镜在多孔介质结构和运输中的工程应用智能价值磁共振显微镜可以在10米(空间分辨)或10纳米(分子运动的整体测量)的空间尺度上以及从10 S到1秒的时间尺度上研究物质中的流动、扩散和空间变化。要研究的多孔材料结构将从生物膜的水凝胶胞外聚合物(EPS)到膜，再到新型先进陶瓷和模型多孔珠包。研究将测量这些材料中的活性核浓度、速度、扩散和磁弛豫，通过孔隙率和曲折度来表征结构，以及量化运输。该研究计划允许继续和扩大目前在生物膜和膜方面的计划，启动和发展陶瓷和聚合物在多孔介质中的传输研究，同时扩大与教学活动的整合。更广泛的影响将在蓬勃发展的职业领域为研究生提供丰富的跨学科研究经验。将开发一门研究生和专业本科生选修课，题为《工程师如何看到材料科学的无损可视化》，并将便携式地球磁场磁共振成像(MRI)设备整合到本科生和外展课程中。整个课程旨在提供对当前材料科学发展前沿的具有社会重要性的材料物理的独特见解。与教育的整合旨在提高学生和更广泛的社区对材料科学研究和令人兴奋的研究应用的跨学科性质的认识，证明工程教育对社会进一步进步的必要性。
