Imaging by Nuclear Magnetic Resonance (NMR) has been established in clinical diagnosis and is conquering materials science with a rapidly expanding number of applications in basic research as well as product and quality control for fluid flow, elastomers, and polymer materials. This book will provide graduate students, scientists and engineers with an introduction to the field. It is the first book on the subject and is likely to become the standard text for years to come.
The use of conventional nuclear magnetic resonance is limited by the fact that the object needs to be carried to the NMR equipment and needs to fit inside large superconducting magnets. Both limitations are removed by single-sided NMR probes based on open magnets specially adapted to the object under study. These can be inexpensive and portable sensors that give access to a large number of applications inaccessible with using conventional magnet geometries. Substantial improvements in the magnet design, detection electronics, and the implementation of suitable techniques to work in the inhomogeneous magnetic fields of open magnets have allowed scientists and engineers to measure relaxation-time distributions, diffusion coefficients, 3D images, velocity distributions, and even highly resolved NMR spectra in the stray field of the magnet. This book is the first comprehensive account describing the key issues to be considered at the time of designing and building open magnets, and summarizing the arsenal of pulse sequences available today for material analysis.
This book describes the design of the first functioning single-sided tomograph, the related measurement methods, and a number of applications in medicine, materials science, and chemical engineering. It will be the first comprehensive account of this new device and its applications. Among the key advances of this method is that images can be obtained in much shorter times than originally anticipated, and that even vector maps of flow fields can be measured although the magnetic fields are highly inhomogeneous. Furthermore, the equipment is small, mobile and affordable to small and medium enterprises and can be located in doctors' offices.
Solid-State NMR is a branch of Nuclear Magnetic Resonance which is presently experiencing a phase of strongly increasing popularity. The most striking evidence is the large number of contributions from Solid-State Resonance atNMR meetings, approaching that ofliquid state resonance. Important progress can be observed in three areas: Methodological developments, applications to inorganic matter, and applications to organic matter. These developments are intented to be captured in three volumes in this series, each of them being devoted to more or less one of these areas. The present volume on Solid-State NMR III is devoted mainly to organic matter. The recent developments of deuteron NMR and their applications are reviewed in the first chapter. Crosspolarization, MAS, and dynamic angle spinning are being explored for enhancement of information and sensitivity. In addition to the analysis of classical relaxation times and modern 2D spectra, detailed dynamic information becomes accessible from investigations of the relaxation time anisotropies. The second chapter examines cross-polarization in static and rotating solids under conditions of spin diffusion and thermal motion. The underlying dipole-dipole interaction is further exploited by the techniques described in the third chapter for studies of polymer-polymer miscibility. Short range techniques are discriminated from long-range techniques based on spin diffusion. The use ofthese techniques is illustrated by a case study ofPMMAJPVF blends. The last chapter addresses novel z methods and applications of two-dimensional exchange NMR for investigations of relative molecular orientations, polymer morphology, molecular dynamics, and macroscopic molecular order."
Imaging by Nuclear Magnetic Resonance (NMR) has been established in clinical diagnosis and is increasingly used in materials science applications. This book will provide graduate students, scientists and engineers with an introduction to the field. It is the first book on the subject and likely to become the standard text for the years to come.
Essential NMR gives scientists and engineers an easy and quick refresher on their NMR knowledge and skills. At the same time, this primer and review affords lecturers material to provide a deliver a framework of basic know-how covering all fields of NMR, i.e. NMR methodology and hardware, chemical analysis, 2D-spectroscopy, NMR imaging, flow NMR, and quality-control NMR. Concise explanatory text, with the key information, is enhanced a color illustration that graphically reinforces understanding. Rigorous derivations are avoided in favor of intuitive arguments. No other teaching-and-learning text addresses all the different aspects of NMR in such a comprehensive and concise fashion.
