Book Description
Nuclear magnetic resonance (NMR) is widely used across many fields of science because of the rich data it produces, and some of the most valuable data come from studies of nuclear spin relaxation in solution. The first edition of this book, published more than a decade ago, provided an accessible and cohesive treatment of the field. The present second edition is a significant update, covering important new developments in recent years. Collecting relaxation theory, experimental techniques, and illustrative applications into a single volume, this book clarifies the nature of the phenomenon, shows how to study it and explains why such studies are worthwhile. Coverage ranges from basic to rigorous theory and from simple to sophisticated experimental methods. Topics include cross-relaxation, multispin phenomena, relaxation studies of molecular dynamics and structure and special topics such as relaxation in systems with quadrupolar nuclei, in paramagnetic systems and in long-living spin states. Avoiding overly demanding mathematics, the authors explain spin relaxation in a manner that anyone with a familiarity with NMR can follow. The focus is on illustrating and explaining the physical nature of relaxation phenomena. Nuclear Spin Relaxation in Liquids: Theory, Experiments and Applications, 2nd edition, provides useful supplementary reading for graduate students and is a valuable reference for NMR spectroscopists, whether in chemistry, physics or biochemistry.

Book Description
The main purpose of this book is to provide in-depth presentation of physical techniques for measuring water transport and their applications to a variety of biological membranes, from model membrane systems to cell membranes, and then from isolated cells to multicellular barrier systems, such as epithelia or even whole organisms. This survey of water transport in such a broad range of membrane systems will hopefully contribute to understanding of the structure-function relationships and molecular mechanisms of water permeation. Moreover, the description of various techniques, together with a review of literature will enable the readers to assess whether a technique would be useful in helping to solve his or her particular problem of research and will also expand their competence in these techniques. The book consists of two volumes.

Book Description
Taking the reader through the underlying principles of molecular translational dynamics, this book outlines the ways in which magnetic resonance, through the use of magnetic field gradients, can reveal those dynamics. The measurement of diffusion and flow, over different length and time scales, provides unique insight regarding fluid interactions with porous materials, as well as molecular organisation in soft matter and complex fluids. The book covers both time and frequency domain methodologies, as well as advances in scattering and diffraction methods, multidimensional exchange and correlation experiments and orientational correlation methods ideal for studying anisotropic environments. At the heart of these new methods resides the ubiquitous spin echo, a phenomenon whose discovery underpins nearly every major development in magnetic resonance methodology. Measuring molecular translational motion does not require high spectral resolution and so finds application in new NMR technologies concerned with 'outside the laboratory' applications, in geophysics and petroleum physics, in horticulture, in food technology, in security screening, and in environmental monitoring.

Book Description
Water Relations of Foods consists of proceedings of an international symposium on "Water Relations of Foods held in Glasgow, in September 1974. Organized into seven sections, the book presents the various papers delivered in the symposium. It describes the physical chemistry of water in simple systems as well as in the more complex food component systems (carbohydrates, lipids, and proteins), with emphasis on the nature of the intermolecular forces involved. It also reports the various techniques used to measure the state of water in food and in model systems made up of food components. Furthermore, the book discusses water activity and the growth of food spoilage and pathogenic organism; water relations of enzymic and non-enzymic deteriorative reactions in food; effects of freezing and thawing of water in food systems; and the significant aspects of food quality as affected by water in the system. Lastly, the modification of the state of water in foods is addressed. This publication will indeed help advance the understanding on this field of interest.

Book Description
This Volume, the last of the series, is devoted to water in its metastable forms, especially at sub-zero temperatures. The past few years have wit nessed an increasing interest in supercooled water and amorphous ice. If the properties of liquid water in the normal temperature range are already eccentric, then they become exceedingly so below the normal freezing point, in the metastable temperature range. Water can be supercooled to -39°C without too much effort, and most of its physical properties show a re markable temperature dependence under these conditions. Although ade quate explanations are still lacking, the time has come to review available knowledge. The study of amorphous ice, that is, the solid formed when water vapor is condensed on a very cold surface, is of longer standing. It has achieved renewed interest because it may serve as a model for the liquid state. There is currently a debate whether or not a close structural relation ship exists between amorphous ice and supercooled water. The nucleation and growth of ice in supercooled water and aqueous solutions is also still one of those grey areas of research, although these topics have received considerable attention from chemists and physicists over the past two decades. Even now, the relationships between degree of supercooling, nucleation kinetics, crystal growth kinetics, cooling rate and solute concentration are somewhat obscure. Nevertheless, at the empirical level much progress has been made, because these topics are of considerable importance to biologists, technologists, atmospheric physicists and gla ciologists.

Book Description
Consumer Driven Cereal Innovation: Where Science Meets Industry includes a collection of papers from oral and poster presentations, along with all the abstracts from the first Spring Meeting organized by Cereals&Europe, the European section of AACC International. These proceedings discuss the major innovation challenges the cereal industry is facing to meet consumers’ demands and expectations. Consumers’ needs are perhaps best summarized as foods that are safe, healthy, and tasty. This book helps answer important questions regarding these essential needs. With respect to safety, the cereal industry can already boast of an excellent reputation and a long tradition of safeguarding cereals and their products. But how can one define “healthy ? How does one distinguish between reality and fiction? If the best ways to add health benefits to cereal products are to be determined, the consumer’s palate needs first to be pleased. What are the most cost-effective ways to manufacture grain-based products for safety, health, and palatability? This conference addressed these important questions and this book is the result of the research and insights of many of the brightest minds in grain science today.
