Muons, radioactive particles produced in accelerators, have emerged as an important tool to study problems in condensed matter physics and chemistry. Beams of muons with all their spins polarized can be used to investigate a variety of static and dynamic effects and hence to deduce properties concerning magnetism, superconductivity, molecular or chemical dynamics and a large number of other phenomena. The technique was originally the preserve of a few specialists located in particle physics laboratories. Today it is used by scientists from a very wide range of scientific backgrounds and interests. This modern, pedagogic introduction to muon spectroscopy is written with the beginner in the field in mind, but also aims to serve as a reference for more experienced researchers. The key principles are illustrated by numerous practical examples of the application of the technique to different areas of science and there are many worked examples and problems provided to test understanding. The book vividly demonstrates the power of the technique to extract important information in many different scientific contexts, all stemming, ultimately, from the exquisite magnetic sensitivity of the implanted muon spin.
Energy storage material is a hot topic in material science and chemistry. During the past decade, nuclear magnetic resonance (NMR) has emerged as a powerful tool to aid understanding of the working and failing mechanisms of energy storage materials and devices.

Nuclear Magnetic Resonance (NMR) has been a fundamental player in the studies of superconducting materials for many decades. This local probe technique allows for the study of the static electronic properties as well as of the low energy excitations of the electrons in the normal and the superconducting state. On that account it has also been widely applied to Fe-based superconductors from the very beginning of their discovery in February 2008. This dissertation comprises some of these very first NMR results, reflecting the unconventional nature of superconductivity and its strong link to magnetism in the investigated compounds LaO1-xFxFeAs and LiFeAs.
Published between 1839 and 1852, this two-volume work records the contribution of William Scoresby (1789-1857) to magnetic science, a field he considered one of 'grandeur'. The result of laborious investigations into magnetism and (with James Prescott Joule) electromagnetism, Scoresby's work was particularly concerned with improving the accuracy of ships' compasses. A whaler, scientist and clergyman, he epitomised the contribution which could be made to exploration and science by provincial merchant mariners - men often less celebrated than their counterparts in the Royal Navy or in metropolitan learned societies. In addition to his pioneering work on magnetic science, Scoresby furthered knowledge of Arctic meteorology, oceanography and geography. Volume 1 considers the magnetism of steel and suggests ways to determine its quality and hardness.

Like the earth itself, the nucleus of an atom frequently rotates about an axis. Under the influence of a magnetic field the axis of rotation itself rotates. The rate of this 'precessional' motion is proportional to the strength of the magnetic field and usually lies in the region of radio-frequencies. If a collection of such nuclei is placed in a magnetic field is subjected to radio waves at exactly the frequency of precession, there is a resonance effect, which can be used to measure the frequency of the precession. This effect is called nuclear magnetic resonance. The subject concerns all physicists, particularly nuclear physicists and those interested in the solid state. It is of growing importance to chemists, metallurgists and electrical engineers and there have been some biological and geophysical applications. Nuclear magnetic resonance has already found considerable uses in the oil industry, in industries connected with magnet construction, isotope extraction, plastics and rubber.
The content of this volume has been added to "eMagRes" (formerly "Encyclopedia of Magnetic Resonance)" - the ultimate online resource for NMR and MRI. To date there is no single reference aimed at teaching the art of applications guided coil design for use in MRI. This" RF Coils for MRI" handbook is intended to become this reference. Heretofore, much of the know-how of RF coil design is bottled up in various industry and academic laboratories around the world. Some of this information on coil technologies and applications techniques has been disseminated through the literature, while more of this knowledge has been withheld for competitive or proprietary advantage. Of the published works, the record of technology development is often incomplete and misleading, accurate referencing and attribution assignment being tantamount to admission of patent infringement in the commercial arena. Accordingly, the literature on RF coil design is fragmented and confusing. There are no texts and few courses offered to teach this material. Mastery of the art and science of RF coil design is perhaps best achieved through the learning that comes with a long career in the field at multiple places of employment...until now. "RF Coils for MRI" combines the lifetime understanding and expertise of many of the senior designers in the field into a single, practical training manual. It informs the engineer on part numbers and sources of component materials, equipment, engineering services and consulting to enable anyone with electronics bench experience to build, test and interface a coil. The handbook teaches the MR system user how to safely and successfully implement the coil for its intended application. The comprehensive articles also include information required by the scientist or physician to predict respective experiment or clinical performance of a coil for a variety of common applications. It is expected that "RF Coils for MRI" becomes an important resource for engineers, technicians, scientists, and physicians wanting to safely and successfully buy or build and use MR coils in the clinic or laboratory. Similarly, this guidebook provides teaching material for students, fellows and residents wanting to better understand the theory and operation of RF coils. Many of the articles have been written by the pioneers and developers of coils, arrays and probes, so this is all first hand information The handbook serves as an expository guide for hands-on radiologists, radiographers, physicians, engineers, medical physicists, technologists, and for anyone with interests in building or selecting and using RF coils to achieve best clinical or experimental results. About "EMR Handbooks / eMagRes Handbooks" The "Encyclopedia of Magnetic Resonance "(up to 2012) and" eMagRes "(from 2013 onward) publish a wide range of online articles on all aspects of magnetic resonance in physics, chemistry, biology and medicine. The existence of this large number of articles, written by experts in various fields, is enabling the publication of a series of "EMR Handbooks / eMagRes Handbooks" on specific areas of NMR and MRI. The chapters of each of these handbooks will comprise a carefully chosen selection of articles from "eMagRes." In consultation with the "eMagRes" Editorial Board, the "EMR Handbooks / eMagRes Handbooks" are coherently planned in advance by specially-selected Editors, and new articles are written (together with updates of some already existing articles) to give appropriate complete coverage. The handbooks are intended to be of value and interest to research students, postdoctoral fellows and other researchers learning about the scientific area in question and undertaking relevant experiments, whether in academia or industry.

Nuclear Magnetic Resonance is a powerful tool, especially for the identification of 1 13 hitherto unknown organic compounds. H- and C-NMR spectroscopy is known and applied by virtually every synthetically working Organic Chemist. Con- quently, the factors governing the differences in chemical shift values, based on chemical environment, bonding, temperature, solvent, pH, etc. , are well understood, and specialty methods developed for almost every conceivable structural challenge. Proton and carbon NMR spectroscopy is part of most bachelors degree courses, with advanced methods integrated into masters degree and other graduate courses. In view of this universal knowledge about proton and carbon NMR spectr- copy within the chemical community, it is remarkable that heteronuclear NMR is still looked upon as something of a curiosity. Admittedly, most organic compounds contain only nitrogen, oxygen, and sulfur atoms, as well as the obligatory hydrogen and carbon atoms, elements that have an unfavourable isotope distribution when it comes to NMR spectroscopy. Each of these three elements has a dominant isotope: 14 16 32 16 32 N (99. 63% natural abundance), O (99. 76%), and S (95. 02%), with O, S, and 34 14 S (4. 21%) NMR silent. N has a nuclear moment I = 1 and a sizeable quadrupolar moment that makes the NMR signals usually very broad and dif cult to analyse.
The combination of two leading imaging techniques - magnetic resonance imaging and positron emission tomography - is poised to have a large impact and has recently been a driver of research and clinical applications. The hybrid instrument is capable of acquiring both datasets simultaneously and this affords a number of advantages ranging from the obvious, two datasets acquired in the time required for one, through to novel applications. This book describes the basics of MRI and PET and then the technical issues and advantages involved in bringing together the two techniques. Novel applications in preclinical settings, human imaging and tracers are described. The book is for students and scientists entering the field of MR-PET with an MRI background but lacking PET or vice versa. It provides practical details from experts working in the area.
Characterisation Methods in Inorganic Chemistry provides a fresh alternative to the existing theoretical and descriptive inorganic chemistry texts by adopting a techniques-based approach and providing problem-solving opportunities to show how analytical methods are used to help us characterise inorganic compounds. The text covers the full range of analytical techniques employed by inorganic chemists, emphasizing those in most frequent use: NMR, diffraction, UV-Vis spectroscopy, and IR. The additional coverage on other techniques allows readers to study these less widely used methods when relevant to their specific course material. Each chapter follows a clear, structured format, which begins with a brief introduction to the technique and basic theory behind it before moving on to data collection and analysis, typical data and interpretation, with numerous worked examples, self- tests and problems.

The idea that a long-lived form of spin order, namely singlet order, can be prepared from nuclear spin magnetisation first emerged in 2004. The unusual properties of singlet order-its long lifetime and the fact that it is NMR silent but interconvertible into other forms of NMR active order-make it a 'smart tag' that can be used to store information for a long time or through distant space points. It is not unexpected then, that since its first appearance, this idea has caught the attention of research groups interested in exploiting this form of order in different fields of research spanning from biology to materials science and from hyperpolarisation to quantum computing. This first book on the subject gives a thorough description of the various aspects that affect the development of the topic and details the interdisciplinary applications. The book starts with a section dedicated to the basic theories of long-lived spin order and then proceeds with a description of the state-of-the-art experimental techniques developed to manipulate singlet order. It then concludes by covering the generalization of the concept of singlet order by introducing and discussing other forms of long-lived spin order.

Some of the advanced topics are included as Appendices for quick reference. Students of chemistry who have some exposure to mathematics and physics will benefit from this book and it will prepare them to pursue research in different branches of Chemistry or Biophysics or Structural Biology.
Written by active investigators in the field, this book describes state-of-the-art methods that can accelerate the acquisition of 2D NMR spectra in solution-state NMR. The acquisition of fast multi-dimensional NMR data has motivated numerous ground-breaking developments in NMR pulse sequences and associated data processing methods. These in turn have revolutionized the way 2D NMR acquisitions are performed, at the same time broadening the scope of applications of 2D NMR. The first part of the book provides an in-depth description of the concepts and implementation of major fast 2D NMR methods. The second part follows with illustrations of how such methods can be used in applications that require the acquisition of fast 2D NMR spectra, from reaction monitoring to hyperpolarization, including applications to a broad variety of samples and experimental conditions. Appealing to readers from both the methodology and applications communities, this title will fill a gap in the market for a book focused on small molecule NMR, and researchers from both academia and industry will find a rich plethora of knowledge.
Since the introduction of FT-NMR spectroscopy around five decades ago, NMR has achieved significant advances in hardware and methodologies, accompanied with the enhancement of spectral resolution and signal sensitivity. Rapid developments in the polymers field mean that accurate and quantitative characterization of polymer structures and dynamics is the keystone for precisely regulating and controlling the physical and chemical properties of the polymer. This book specifically focuses on NMR investigation of complex polymers for the polymer community as well as NMR spectroscopists, and will push the development of both fields. It covers the latest advances, for example high field DNP and ultrafast MAS methodologies, and show how these novel NMR methods characterize various synthetic and natural polymers.

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.
