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.

The narrow pulse approximation and long length scale determination in xenon gas diffusion NMR studies of model porous media.
TL;DR: It is found that the time-dependent diffusion coefficient, D(t), of the imbibed xenon gas at short diffusion times in small beads is significantly affected by the gas pressure, resulting from reduced diffusion during the application of the gradient pulse.

Fiber tracking using magnetic resonance diffusion tensor imaging and its applications to human brain development.
TL;DR: The noninvasive nature of magnetic resonance imaging will allow these techniques to be used in both longitudinal developmental and diagnostic studies, and both the identification of the eloquent areas of the brain involved in specific functional tasks, and the connections between them.

TL;DR: The testis contains large amounts of creatine, of which a substantial proportion was shown to be extracellular using bipolar gradients to measure apparent diffusion coefficients and the tissue also contained relatively high amounts of uridine.

Gaussian approximation in the theory of MR signal formation in the presence of structure-specific magnetic field inhomogeneities
TL;DR: A detailed theoretical analysis of the free induction decay (FID) and spin echo (SE) MR signal formation in the presence of mesoscopic structure-specific magnetic field inhomogeneities is developed in the framework of the Gaussian phase distribution approximation.

Complexes of Macrocycles with gamma-Cyclodextrin As Deduced from NMR Diffusion Measurements.
Ayelet Gafni,Yoram Cohen +1 more
TL;DR: The complexes of 12-crown-4 (12C4), cyclen (12N4), and 1,4,7,10-tetrathiacyclodododecane (12S4) with gamma-cyclodextrin (gamma-CD) were studied by NMR diffusion measurements in the absence and in the presence of inorganic and organic salts, suggesting that the hydrophobic interaction is not the main driving force for complexation in these systems.
