The Kärger vs bi-exponential model: theoretical insights and experimental validations
Nicolas Moutal, Markus Nilsson, Daniel Topgaard +1
We revise three common models accounting for water exchange in pulsed-gradient spin-echo measurements: a bi-exponential model with time-dependent water fractions, the Kärger model,…
Localization regime in diffusion NMR: theory and experiments
Nicolas Moutal, Kerstin Demberg, Denis Grebenkov +1
In this work we investigate the emergence of the localization regime for diffusion in various geometries: inside slabs, inside cylinders and around rods arranged on a square array.…
Probing surface-to-volume ratio of an anisotropic medium by diffusion {NMR} with general gradient encoding
Nicolas Moutal, Ivan I. Maximov, Denis S. Grebenkov
Since the seminal paper by Mitra et al., diffusion MR has been widely used in order to estimate surface-to-volume ratios. In the present work we generalize Mitra's formula for arbi…
