Abstract: Translational motion in solution, either diffusion or fluid flow, is at the heart of chemical and biochemical reactivity. Nuclear Magnetic Resonance (NMR) provides a powerful non-invasive technique for studying the phenomena using magnetic field gradient methods. Describing the physical basis of measurement techniques, with particular emphasis on diffusion, balancing theory with experimental observations and assuming little mathematical knowledge, this is a strong, yet accessible, introduction to the field. A detailed discussion of magnetic field gradient methods applied to Magnetic Resonance Imaging (MRI) is included, alongside extensive referencing throughout, providing a timely, definitive book to the subject, ideal for researchers in the fields of physics, chemistry and biology.

TL;DR: A microstructure model, the diffusion tensor distribution (DTD) model, is proposed, which takes advantage of additional information provided by QTI to estimate a distributional model over diffusion tensors.

Microanisotropy imaging: quantification of microscopic diffusion anisotropy and orientational order parameter by diffusion MRI with magic-angle spinning of the q-vector
TL;DR: In this paper, a new parameter called microscopic fractional anisotropy (µFA) was proposed, which corresponds to the FA without the confounding influence of orientation dispersion.
Criteria for solvate ionic liquids
TL;DR: This perspective paper describes possible criteria for the new family of ionic liquids: "solvate" ionic liquid, originally proposed by Angell et al. in their recent review; however, their criteria remain to be debated.

Transport properties of hierarchical micro–mesoporous materials
TL;DR: This review summarizes the results obtained so far on experimental and theoretical studies of diffusion in micro-mesoporous materials and discusses four common classes of bi-porous materials, which are differing by the inter-connectivities of their sup-spaces as one of the most important parameter determining the transport rates.
Multidimensional diffusion MRI
TL;DR: The basic physics of solid-state NMR and diffusion MRI are revisited to pinpoint the origin of the somewhat unexpected analogy between the two fields, and an overview of current diffusion MRI acquisition protocols and data analysis methods are provided to quantify the composition of heterogeneous materials in terms of diffusion tensor distributions with size, shape, and orientation dimensions.

Measurement of Biomolecular Diffusion Coefficients in Blood Plasma Using Two-Dimensional 1H−1H Diffusion-Edited Total-Correlation NMR Spectroscopy
TL;DR: Two-dimensional diffusion-edited total-correlation NMR spectroscopy (DETOCSY) to measure diffusion coefficients of molecules in biofluids and interpretation of the derived diffusion coefficients improves the NMR resonance assignment process in complex biofluid mixtures.

Correlations between dispersion and structure in porous media probed by nuclear magnetic resonance
TL;DR: In this article, the structure of the pore space is characterized from the MRI images by determining radial distribution functions for the Pore space and the dispersion transverse to the direction of superficial flow is dominated by Taylor dispersion, even for flow within a single pore.

TL;DR: In this paper, the diffusion-time dependence of diffusion-weighted magnetic resonance (MR) signal in biological tissues is investigated. But the authors focus on the diffusion in disordered media, where two parameters, the random walk dimension and spectral dimension, describe the evolution of the average propagators obtained from q-space MR experiments.

TL;DR: The PGMSE technique is found to be superior to the PGE method, and to standard PGSE techniques and variants, for efficiently measuring laser polarized noble gas diffusion over a wide range of diffusion times.
