0111278KnightThis grant provides 50% of the costs of acquiring a Maran Ultra NMR core analyzer for the Environmental Geophysics Laboratory currently being built at Stanford University. The instrumentation will be used by the PI and graduate students investigating the use of NMR for environmental applications. In addition, it is likely that others will use the analyzer for research applications in the petroleum industry. There is growing interest in the use of NMR for characterizing the near-surface of the earth. The Maran analyzer is the central piece of equipment that will be used for laboratory studies of the relationship between measured NMR parameters and the basic physical and chemical properties of porous geological materials. The analyzer will be used to investigate the link between the NMR time constants and both the pore size distribution and tortuosity of materials. A second focus will be on improving the fundamental understanding of the mechanisms that control the NMR response in geological materials, with an emphasis on determining the role of paramagnetic species and the sensitivity to sorbed contaminants. This analyzer will be the first low field instrument of its kind at Stanford University, providing the capability to obtain laboratory data at the same frequency as that used in the collection of field and borehole data. The Maran analyzer will be housed in the Environmental Geophysics Laboratory, planned for construction in the summer of 2001. ***

0111278骑士这笔赠款提供了50%的费用，购买马兰超核磁共振核心分析仪的环境地球物理实验室目前正在建设的斯坦福大学。 仪器将用于PI和研究生调查使用NMR的环境应用。 此外，其他人可能会将分析仪用于石油工业的研究应用。 利用核磁共振技术来表征地球近地表的特性越来越受到人们的关注。 Maran分析仪是核心设备，将用于实验室研究测量的NMR参数与多孔地质材料的基本物理和化学性质之间的关系。 该分析仪将用于研究NMR时间常数与材料的孔径分布和弯曲度之间的联系。 第二个重点将是提高对控制地质材料中NMR响应的机制的基本理解，重点是确定顺磁性物质的作用和对吸附污染物的敏感性。 这一分析仪将是斯坦福大学第一台此类低场仪器，能够以与采集现场和钻孔数据相同的频率获取实验室数据。 Maran分析仪将安置在计划于2001年夏季建造的环境地球物理实验室内。 ***
