CTS-9610317 Snurr & Torkelson Northwestern University Project Summary The Department of Chemical Engineering at Northwestern University will purchase equipment for performing nuclear magnetic resonance. (NMR) diffusion measurements on an existing NMR spectrometer at Northwestern. The equipment con- sists of a diffusion package, including an amplifier and spectrometer software, as well as a custom-built pulsed field gradient NMR diffusion probe. The equipment will be dedicated to support research in engineering. It will be used for several research projects, including 1) and investigation of mass transfer effects in zeolite catalysis, 2) studies of multicomponent diffusion in zeolites, 3) research on small-molecule diffusion in polymer solutions, 4) studies of polymer diffusion in polymer situations and 5) investigations of small-molecule diffusion in bulk polymers. As part of the general user facility that maintains the NMR spectrometer, the new equipment will be made available to researchers working on other projects as well.

9610317 SNurr&Amp；Torkelson西北大学项目摘要西北大学化学工程系将采购进行核磁共振的设备。在西北大学现有的核磁共振波谱仪上进行的(核磁共振)扩散测量。该设备包括扩散组件，包括放大器和光谱仪软件，以及定制的脉冲场梯度核磁共振扩散探头。这些设备将专门用于支持工程研究。它将用于几个研究项目，包括1)沸石催化传质效应的研究，2)沸石中多组分扩散的研究，3)小分子在聚合物溶液中的扩散研究，4)聚合物在聚合物中的扩散研究，5)小分子在本体聚合物中的扩散研究。作为维护核磁共振光谱仪的通用用户设施的一部分，新设备也将提供给从事其他项目的研究人员。
