GOALI: Dynamics of Molecules as a Probe of Pore Space

abstractcts - 0109433 d。G. Cory， mit这个基于核磁共振（NMR）的方案，是分析多孔材料结构和流动的前沿，重点是地球物理勘探。该方法将显著提高核磁共振相干平均方法在探索和表征流体在多孔材料中运移的结构和动力学方面的有效性。核磁共振信号分为各向同性谱、频率调制和幅度调制。这些组分可以报告流动相的化学性质、基本场变化以及固相与流动相迁移率的时间/长度尺度相关性。明年的工作重点是抑制频率调制的核磁共振相干平均方案的设计理念，从调幅项中提取与模型无关的度量，最后考虑这些复杂系统中的逆问题。这将是该技术前沿的重大发展。这项工作是由大学/工业（麻省理工学院和斯伦贝谢）与每个组织的共同pi合作完成的。工业合作伙伴为该项目做出了重大贡献，包括工业共同pi的时间。更广泛的影响拟议的项目处于核磁共振技术的前沿，在两个方面具有更广泛的影响。首先，该项目涉及培养具有独特专业知识的研究生。从更广泛的角度来看，该方法适用于许多工业和生物过程，包括对材料的探索，这在目前是不可能的。由于拟议的项目确实处于一项重大技术的前沿，范围仅限于整个研究计划的主要创新方面，以及大学与工业合作伙伴之间的有效合作，因此建议修订后的项目作为GOALI项目获得资助。

AbstractCTS-0109433D. G. Cory, MITThis proposal, based on Nuclear Magnetic Resonance (NMR), is at the forefront of analysis of the structure and flow in porous material, with emphasis to geophysical exploration. The method will significantly improve the effectiveness of NMR to explore and characterize the structure and the dynamics of fluid transport through the porous material by coherent averaging. The NMR signature is separated in to an isotropic spectrum, a frequency modulation, and an amplitude modulation. These components can report on the chemistry of the mobile phase, the basic field variations, and the time/length scale correlation of the solid phase and the mobility of the mobile phase.The proposed work for next year is focused on the design philosophy for the NMR coherent averaging scheme that suppress frequency modulations, extracting the model independent metrics from the amplitude modulation term, and finally to consider the inverse problem in these complex systems. This would be a significant development at the forefront of this technology.This work is in collaboration between university/industry (MIT and Schlumberger) with a co-PI from each organization. The industrial partner is making substantial contribution to the project including the time of the co-PI from the industry.BROADER IMPACTThe proposed project being at the forefront of NMR technology has broader impact in two fronts. First, the program involves training graduate students with a unique set of expertise. On a more general front, the method is applicable to many industrial and biological processes including exploration of material with insight that currently is not possible.Since the proposed project is truly at the forefront of a major technology, and the scope is limited to the major innovative aspects of the overall research program, and the effective collaboration between the university and the industrial partner, the revised project is recommended for funding as a GOALI project.
