Download or read book Compact NMR written by Bernhard Blümich and published by Walter de Gruyter GmbH & Co KG. This book was released on 2014-08-22 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this book is to provide an introduction to the practical use of mobile NMR at a level as basic as the operation of a smart phone. Each description follows the same didactic pattern: introduction, basic theory, pulse sequences and parameters, beginners-level measurements, advanced-level measurements, and data processing. Nuclear Magnetic Resonance (NMR) spectroscopy is the most popular method for chemists to analyze molecular structures while Magnetic Resonance Imaging (MRI) is a non-invasive diagnostic tool for medical doctors that provides high-contrast images of biological tissue depicting the brain function and the beating heart. In both applications large super-conducting magnets are employed which magnetize atomic nuclei of an object positioned inside the magnet. Their circulating motion is interrogated by radio-frequency waves. Depending on the operating mode, the frequency spectrum provides the chemist with molecular information, the medical doctor with anatomic images, while the materials scientist is interested in NMR relaxation parameters, which scale with material properties and determine the contrast in magnetic resonance images. Recent advances in magnet technology led to a variety of small permanent magnets, by which NMR spectra, images, and relaxation parameters can be measured with mobile and low-cost instruments.

This book was released on 2010-04-07 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: 40th anniversary of "medical uses of SQUID" th It is my great pleasure and honor to invite you to the 17 International Conference on Biomagnetism – Biomag2010 held in Dubrovnik, Croatia from Sunday, March 28 through Thursday, April 1, 2010. The interdisciplinary field of biomagnetism includes dynamic and evolving SQUID-based technologies offering advanced real-time methods for noninvasive assessments of magnetic signals from the brain, heart and other organs as well as a range of modeling, mathematical and computational methods for functional source localization approaches. Excellent spatial resolution and unique, millisecond, temporal resolution of biomagnetic techniques allow insights into cortical neurodynamics and neurobiological basis of the human brain as well as assessment of heart and other organs functions in health and disease. Biomag2010 will be a great opportunity for an exchange of ideas and presentation of the latest developments in instrumentation, modeling approaches, basic and clinical biomedical studies. We are particularly proud to announce the celebration of the 40th anniversary of the first SQUID-based MCG measurements published on April 1, 1970. Since then ''medical uses of SQUID'' were dynamic and growing, including the most recent developments, in combination with a low field MRI, toward a ''direct neuronal imaging''. Dubrovnik, the host city of the Biomag2010, a jewel on the Adriatic, will be a superb and stimulating setting for both scientific and social aspects of this meeting. I am looking forward to hosting you in Dubrovnik, Croatia in spring of 2010.

Download or read book Advances in Pulsed Zero Field NMR written by Tobias Fredrik Sjolander and published by . This book was released on 2017 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear Magnetic Resonance (NMR) is ubiquitous as a tool for investigating the structure of both molecules and materials. In most cases the best results are obtained by placing the sample under study in the largest possible magnetic field, since this maximizes both the sensitivity and the resolution of the experiment. This fact underlies the momentous engineering effor that has gone into developing ever larger super-conducting magnets for use in NMR experiments. However, there are many applications of NMR where the sheer size, not to mention cost, of a high-field instrument can not be accommodated. Therefore there has been a sustained research effort aimed at developing small mobile NMR systems that are not based on super-conducting magnets. NMR performed in zero-field, using magnetic shielding to screen out the ambient field of the earth, and detected using vapor-cell magnetometers, is one such approach. In zero-field NMR the signal originates entirely in the spin-spin coupling part of the Hamiltonian and chemically informative spectra are obtained even in the absence of chemical-shifts. The very large absolute field homogeneity obtainable at zero-field ensures that the spectral resolution is even better than in high-field spectrometers. Perhaps even more interestingly, the different geometry that results from not having a preferred axis imposed on the system enables experiments that are not possible in the presence of magnetic fields. Examples include the ability to distinguish enantiomers based on the phase of an NMR signal. This work extends directly detected zero-field NMR beyond pulse-acquire type experiments. New methods for spin control and excitation, as well as two-dimensional spectroscopy and various decoupling techniques are introduced and demonstrated experimentally. For completeness this dissertation also contains a review of zero-field J-spectroscopy, as well as a detailed guide to the relevant instrumentation. It is my hope that the techniques presented herein will find use in future NMR experiments performed in the regime of zero and ultralow field, whether the application is portable chemical analysis, fundamental physics, or anything in between.

Download or read book Practical Applications of NMR to Solve Real World Problems written by Robert Brinson and published by Mdpi AG. This book was released on 2021-12-02 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear magnetic resonance spectroscopy (NMR) has developed from primarily a method of academic study into a recognized technology that has advanced measurement capabilities within many different industrial sectors. These sectors include areas such as national security, energy, forensics, life sciences, pharmaceuticals, etc. Despite this diversity, these applications have many shared technical challenges and regulatory burdens, yet interdisciplinary cross-talk is often limited. To facilitate the sharing of knowledge, this Special Issue presents technical articles from four different areas, including the oil industry, nanostructured systems and materials, metabolomics, and biologics. These areas use NMR or magnetic resonance imaging (MRI) technologies that range from low-field relaxometry to magnetic fields as high as 700 MHz. Each article represents a practical application of NMR. A few articles are focused on basic research concepts, which will likely have the cross-cutting effect of advancing multiple disciplinary areas.

Download or read book Ultra Low Field Nuclear Magnetic Resonance written by Robert Kraus Jr. and published by Oxford University Press. This book was released on 2014-02-26 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed to introduce the reader to the field of NMR/MRI at very low magnetic fields, from milli-Tesla to micro-Tesla, the ultra-low field (ULF) regime. The book is focused on applications to imaging the human brain, and hardware methods primarily based upon pre-polarization methods and SQUID-based detection. The goal of the text is to provide insight and tools for the reader to better understand what applications are best served by ULF NMR/MRI approaches. A discussion of the hardware challenges, such as shielding, operation of SQUID sensors in a dynamic field environment, and pulsed magnetic field generation are presented. One goal of the text is to provide the reader a framework of understanding the approaches to estimation and mitigation of low signal-to-noise and long imaging time, which are the main challenges. Special attention is paid to the combination of MEG and ULF MRI, and the benefits and challenges presented by trying to accomplish both with the same hardware. The book discusses the origin of unique relaxation contrast at ULF, and special considerations for image artifacts and how to correct them (i.e. concomitant gradients, ghost artifacts). A general discussion of MRI, with special consideration to the challenges of imaging at ULF and unique opportunities in pulse sequences, is presented. The book also presents an overview of some of the primary applications of ULF NMR/MRI being pursued.
