Tortuosity Measurement and the Effects of Finite Pulse Widths on Xenon Gas Diffusion NMR Studies of Porous Media
R. W. Mair, M. D. Hurlimann, P. N. Sen +3
We have extended the utility of NMR as a technique to probe porous media structure over length scales of ~ 100 - 2000 micron by using the spin 1/2 noble gas 129Xe imbibed into the…

The Narrow Pulse Approximation and long length scale determination in xenon gas diffusion NMR studies of model porous media
R. W. Mair, P. N. Sen, M. D. Hurlimann +3
We report a systematic study of xenon gas diffusion NMR in simple model porous media: random packs of mono-sized glass beads, and focus on three specific areas peculiar to gas-phas…

Applications of controlled-flow laser-polarized xenon gas to porous and granular media study
R. W. Mair, R. Wang, M. S. Rosen +3
We report initial NMR studies of continuous flow laser-polarized xenon gas, both in unrestricted tubing, and in a model porous media. The study uses Pulsed Gradient Spin Echo-based…
