Recent developments in nanoparticle and microparticle delivery systems are revolutionizing delivery systems in the food industry. These developments have the potential to solve many of the technical challenges involved in creating encapsulation, protection, and delivery of active ingredients, such as colors, flavors, preservatives, vitamins, minerals, and nutraceuticals. Nanoparticle- and Microparticle-based Delivery Systems: Encapsulation, Protection and Release of Active Compounds explores various types of colloidal delivery systems available for encapsulating active ingredients, highlighting their relative advantages and limitations and their use. Written by an international authority known for his clear and rigorous technical writing style, this book discusses the numerous kinds of active ingredients available and the issues associated with their encapsulation, protection, and delivery. The author takes a traditional colloid science approach and emphasizes the practical aspects of formulation of particulate- and emulsion-based delivery systems with food applications. He then covers the physicochemical and mechanical methods available for manufacturing colloidal particles, highlighting the importance of designing particles for specific applications. The book includes chapters devoted specifically to the three major types of colloidal delivery systems available for encapsulating active ingredients in the food industry: surfactant-based, emulsion-based, and biopolymer-based. It then reviews the analytical tools available for characterizing the properties of colloidal delivery systems, presents the mathematical models for describing their properties, and highlights the factors to consider when selecting an appropriate delivery system for a particular application backed up by specific case studies. Based on insight from the author's own experience, the book describes why delivery systems are needed, the important factors to consider when designing them, methods of characterizing them, and specific examples of the range of food-grade delivery systems available. It gives you the necessary knowledge, understanding, and appreciation of developments within the current research literature in this rapidly growing field and the confidence to perform reliable experimental investigations according to modern international standards.
Recent advances in both experimental techniques and theoretical methodologies have meant that increasingly sophisticated studies concerning the formation, structures, energetics and reaction dynamics of state- or energy-selected molecular ions can now be performed. In order to better serve the ion chemistry and physics community, each volume of this series is dedicated to reviewing a specific topic, emphasizing new experimental and theoretical developments in the study of ions. The Wiley Series in Ion Chemistry and Physics will help stimulate new research directions and point to future opportunities in the field of ion chemistry and physics. This volume, the fifth in the series, concentrates on the important area of organic ions. Our understanding of these ions has been significantly improved over the last decade due to both theoretical and experimental advances, and it is now routinely possible to calculate organic ion structures by ab initio molecular orbital methods with very high precision. At the same time, the experimental tools used to study organic ions have become much more refined. This volume provides a timely overview of some of the key approaches which are currently producing such important results in the study of negative ions, and contains seven chapters written by acknowledged experts in the field. It will be of great interest to both experts and newcomers, both of whom will benefit from the in-depth discussion of the latest methods and results.

Nuclear magnetic resonance (NMR) spectroscopy, a technique widely used for structure determination by chemists and biochemists, is based on the detection of tiny radio signals emitted by the nucleus of an atom when immersed in a strong magnetic field. Every chemical substance gives rise to a recognizable NMR signature closely related to its molecular structure. This comprehensive account adopts an accessible, pictorial approach to teach the fundamental principles of high resolution NMR. Mathematical formalism is used sparingly, and everyday analogies are used to provide insight into the physical behaviour of nuclear spins. The first three chapters set out the basic tools for understanding the rest of the book. Each of the remaining chapters provides a self- contained reference to a specific theme, for example spin echoes, and traces the way it influences our understanding of high resolution NMR methodology. Spin Choreography provides a clear and an authoritative introduction to the fundamental principles of high resolution NMR, which will appeal to all practitioners who wish to master this complex but fascinating subject. The book will also serve as supplementary reading for upper-level undergraduate and graduate courses on spectroscopy and physical methods.

The book illustrates the fascinating world of the different forms of water - from ice and snow to liquid water. The water molecule, H2O, is the second most common molecule in the Universe (behind hydrogen, H2) and ice is the most abundant solid material. Snow and ice appear in a countless large number of different shapes and with properties which can be quite different. Detailed knowledge of the properties of snow is of great importance for the Sami people involved in reindeer herding and several hundred names are used to characterize the different types.The properties of ice and liquid water are very special and unique in several respects. In contrast to most other substances, the density of ice is lower than that of liquid water, which has many very important consequences in our daily life. Water plays a unique role in chemistry and although tremendous research has been spent on this seemingly simple substance, there are still many unsolved questions about the structure of liquid water. The special properties of water are due to hydrogen bonding between the H2O molecules, and this book may be seen as a tribute to the hydrogen bond. The general properties of the hydrogen bond are treated in three separate papers. The hydrogen bond is of fundamental importance in biological systems since all living matter has evolved from and exists in an aqueous environment and hydrogen bonds are involved in most biological processes. There is a hundred times more water molecules in our bodies than the sum of all the other molecules put together.

Physical and biological systems driven out of equilibrium may spontaneously evolve to form spatial structures. In some systems molecular constituents may self-assemble to produce complex ordered structures. This book describes how such pattern formation processes occur and how they can be modeled. Experimental observations are used to introduce the diverse systems and phenomena leading to pattern formation. The physical origins of various spatial structures are discussed, and models for their formation are constructed. In contrast to many treatments, pattern-forming processes in nonequilibrium systems are treated in a coherent fashion. The book shows how near-equilibrium and far-from-equilibrium modeling concepts are often combined to describe physical systems. This inter-disciplinary book can form the basis of graduate courses in pattern formation and self-assembly. It is a useful reference for graduate students and researchers in a number of disciplines, including condensed matter science, nonequilibrium statistical mechanics, nonlinear dynamics, chemical biophysics, materials science, and engineering.

Nanoparticles can be viewed as a new type of 'atom' with size dependent physical, optical and electronic properties that make them suitable for a wide variety of applications. There are many open questions in the field of nanoparticle synthesis and assembly: how does the nanoparticle-nanoparticle potential govern nanoparticle formation or assembly? Can we design a nanoparticle from the ground up, according to theoretical predictions, which will self-assemble into a given nanoparticle superlattice structure? How does the assembly process vary with nanoparticle shape and the ligand coating which surrounds each nanoparticle? The answers to these questions require the coordination and collaboration of nanoparticle theorists, synthesizers, and assemblers. Following the Nanoparticle Synthesis and Assembly: Faraday Discussion (April 2015), this book brings together a diverse group of scientists to deliberate the latest developments in nanoparticle theory, synthesis and assembly and to generate new ideas and engender new collaborations between these groups.
