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.

NMR measurements of diffusion in concentrated samples: avoiding problems with radiation damping.
TL;DR: Pulsed field gradient spin echo NMR is generally the method of choice for diffusion measurements on liquid samples, however, severe problems can arise when it is applied to samples with very high proton concentrations because of the presence of radiation damping.

TL;DR: The self-diffusion of different species in highly concentrated water-in-oil emulsions was investigated by means of the NMR diffusometry approach and acetic acid/acetate ions diffused between the droplets and had exchange times which were a function of pH.

TL;DR: In this article, Jonsson et al. calculated the effective translational self-diffusion coefficient of small molecules in colloidal crystals of spherical particles and analyzed the results for three different cubic lattice types.

Flow effects in long-range dipolar field MRI.
TL;DR: The theoretical analysis and experimental results show how the effect of the distant dipolar field can be annihilated by flow, and indicate that MSE is flow-sensitive.
