The manipulation of cells and microparticles within microfluidic systems using external forces is valuable for many microscale analytical and bioanalytical applications. Acoustofluidics is the ultrasound-based external forcing of microparticles with microfluidic systems. It has gained much interest because it allows for the simple label-free separation of microparticles based on their mechanical properties without affecting the microparticles themselves. Microscale Acoustofluidics provides an introduction to the field providing the background to the fundamental physics including chapters on governing equations in microfluidics and perturbation theory and ultrasound resonances, acoustic radiation force on small particles, continuum mechanics for ultrasonic particle manipulation, and piezoelectricity and application to the excitation of acoustic fields for ultrasonic particle manipulation. The book also provides information on the design and characterization of ultrasonic particle manipulation devices as well as applications in acoustic trapping and immunoassays. Written by leading experts in the field, the book will appeal to postgraduate students and researchers interested in microfluidics and lab-on-a-chip applications.

Traditional Chinese medicine has a strong scientific basis, but the science of these important preparations is often rarely discussed. Western approaches often simplify traditional Chinese medicine to drug discovery in Chinese plants, however, the majority of traditional Chinese medications use complex mixtures of plant extracts, rather than single purified drugs. The combination of different extracts is based on yin, yang and chi theories, which are often poorly understood in the West. Yin and yang are known to be the balance of agonists and antagonists, whereas chi derives from signalling processes in the body and regulates bodily functions. Traditional Chinese medical practitioners understand that yin, yang and chi constantly interact in the body to maintain health. Western medical practitioners understand how to use agonists and antagonists and how to modify signalling processes, but generally do not accept the use of complex plant extracts to perform these functions. Aimed at medical scientists, and including detailed explanations of the theories behind the science, this text may help researchers to understand Chinese medical practitioners and to communicate more effectively with them. It will also lead to greater acceptance of traditional medications in the West. Presenting a clear rationale for the use of traditional Chinese medications in Western medical facilities, it enables scientists to find new directions in experimental design and encourage examination of these useful, but often poorly understood, preparations in clinical trials.

Photovoltaic systems enable the sun’s energy to be converted directly into electricity using semiconductor solar cells. The ultimate goal of photovoltaic research and development is to reduce the cost of solar power to reach or even become lower than the cost of electricity generated from fossil and nuclear fuels. The power conversion efficiency and the cost per unit area of the phototvoltaic system are critical factors that determine the cost of photovoltaic electricity. Until recently, the power conversion efficiency of single-junction photovoltaic cells has been limited to approximately 33% - the socalled Shockley-Queisser limit. This book presents the latest developments in photovoltaics which seek to either reach or surpass the Shockley-Queisser limit, and to lower the cell cost per unit area. Progress toward this ultimate goal is presented for the three generations of photovoltaic cells: the 1st generation based on crystalline silicon semiconductors; the 2nd generation based on thin film silicon, compound semiconductors, amorphous silicon, and various mesoscopic structures; and the 3rd generation based on the unique properties of nanoscale materials, new inorganic and organic photoconversion materials, highly efficient multi-junction cells with low cost solar concentration, and novel photovoltaic processes. The extent to which photovoltaic materials and processes can meet the expectations of efficient and cost effective solar energy conversion to electricity is discussed. Written by an international team of expert contributors, and with researchers in academia, national research laboratories, and industry in mind, this book is a comprehensive guide to recent progress in photovoltaics and essential for any library or laboratory in the field.

Food additives have played and still play an essential role in the food industry. Additives span a great range from simple materials like sodium bicarbonate, essential in the kitchen for making cakes, to mono- and diglycerides of fatty acids, an essential emulsifier in low fat spreads and in bread. It has been popular to criticise food additives, and in so doing, to lump them all together, but this approach ignores their diversity of history, source and use. This book includes food additives and why they are used, safety of food additives in Europe, additive legislation within the EU and outside Europe and the complete listing of all additives permitted in the EU. The law covering food additives in the EU which was first harmonised in 1989 has been amended frequently since then, but has now been consolidated with the publication of Regulations 1331/2008 and 1129/2011. This 4th edition of the Guide brings it up to date with the changes introduced by this legislation and by the ongoing review of additives by EFSA. Providing an invaluable resource for food and drink manufacturers, this book is the only work covering in detail every additive, its sources and uses. Those working in and around the food industry, students of food science and indeed anyone with an interest in what is added to their food will find this a practical book full of fascinating details.

This book is divided into two parts. The first covers biomass modification to facilitate the industrial degradation processing and other characteristics of feedstocks. These include reduction in the general recalcitrance of plant cell wall and downstream processing costs. The second focuses on cutting edge technologies for the conversion of lignocelluloses into biofuels and other products. It describes the most up-to-date advances in natural biomass utilization systems, such as wood-feeding termites and animals that efficiently degrade lignocellulosic substrates. Consolidated bioprocessing (CBP) integrates cellulase production and cellulose hydrolysis, with pentose and hexose fermentation in a single step. This replicates what happens in the digestive systems of animals, such as termites and cows, that effectively degrade lignocellulosic substrates. CBP has the potential to reduce production costs and lower capital investment whilst increasing conversion efficiency. Currently, there are no CBP-enabling micro-organisms suitable for industrial applications. Consequently, this book presents technologies which integrate the lignocellulolytic systems of insects and other animals to advance CBP strategy for cellulosic biofuels. It covers the progress made, and challenges faced, with the utilisation of gene, catalyst, and other unique mechanisms from cellulose-eating animals, as well as cutting-edge technologies developed to reduce the general recalcitrance of feedstocks for processing. This volume makes essential reading for academics and industrial groups concerned with overcoming the challenges inherent in the biological conversion of biomass into fuels and chemicals.

A series of critical reviews and perspectives focussing on specific aspects of organometallic chemistry interfacing with other fields of study are provided. For this volume, the critical reviews cover topics such as the activation of "inert" carbon-hydrogen bonds, ligand design and organometallic radical species. For example, Charlie O'Hara discusses how mixed-metal compounds may perform the highly selective activation of C-H bonds and, in particular, how synergic relationships between various metals are crucial to this approach. The chemistry of a remarkable series of air-stable chiral primary phosphine ligands is discussed in some depth by Rachel Hiney, Arne Ficks, Helge M³ller-Bunz, Declan Gilheany and Lee Higham. This article focuses on the preparation of these ligands and also how they may be applied in various catalytic applications. Bas De Bruin reports on how ligand radical reactivity can be employed in synthetic organometallic chemistry and catalysis to achieve selectivity in radical-type transformations. As well as highlighting ligand-centered radical transformations in open-shell transition metals, an overview of the catalytic mechanism of Co(II)-catalysed olefin cyclopropanation is given, showing that enzyme-like cooperative metal-ligand-radical reactivity is no longer limited to real enzymes. Valuable and informative comprehensive reviews in the field of organometallic chemistry are also covered in this volume. For example, organolithium and organocuprate chemistry are reviewed by Joanna Haywood and Andrew Wheatley; aspects in Group 2 (Be-Ba) and Group 12 (Zn-Hg) compounds by Robert Less, Rebecca Melen and Dominic Wright; metal clusters by Mark Humphrey and Marie Cifuentes; and recent developments in the chemistry of the elements of Group 14 - focusing on low-coordination number compounds by Richard Layfield. This volume therefore covers many synthetic and applied aspects of modern organometallic chemistry which ought to be of interest to inorganic, organic and applied catalysis fields.

Currently, the health of over half the adult population in the UK suffers because of fat. The UK is not alone: obesity is a global problem, but the populations of some countries are heavier than others. This book probes the chemistry of fat in our bodies, providing a unique insight into understanding obesity, and how this material becomes accumulated to cause obesity with particular emphasis on the contribution of nutrition beyond calories. It visits the current hot topic of the genetic origins of obesity and progresses through to the relatively under publicised field of epigenetics, emphasising its importance to understanding the current epidemic. Coming in the wake of the establishment of international collaborations, the book aims to quantify the extent of the contribution of nutritional deficiencies to body weight gain. Yet even before these studies begin some important links have been identified and the molecular mechanisms by which they induce obesity have been mapped. This information reveals a serious problem for the next generation, but it is expected to provide the necessary information to tackle the obesity epidemic. Based on an extensive review of scientific literature, this topical book is written in a way that is accessible to the non-specialist. Suitable for the general public, the principal focus of the book is to advance the public understanding and awareness of science through the high interest subject of obesity. However, many universities recommend public understanding of science texts to students as a means of broadening general knowledge and as a means to emphasise to students the importance of communicating their research to the public. This book will be instrumental in developing this knowledge.

From crystal structure prediction to totally empirical screening, the quest for new crystal forms has become one of the most challenging issues in the solid state science and particularly in the pharmaceutical world. In this context, multi-component crystalline materials like co-crystals have received renewed interest as they offer the prospect of optimized physical properties. As illustrated in this first book_ entirely dedicated to this emerging class of pharmaceutical compounds_ the outcome of such endeavours into crystal engineering have demonstrated clear impacts on production, marketing and intellectual property protection of active pharmaceutical ingredients (APIs). Indeed, co-crystallization influences relevant physico-chemical parameters (such as solubility, dissolution rate, chemical stability, melting point, hygroscopicity, à) and often offers solids with properties superior to those of the free drug. Combining both reports of the latest research and comprehensive overviews of basic principles, with contributions from selected experts in both academia and industry, this unique book is an essential reference, ideal for pharmaceutical development scientists and graduate students in pharmaceutical science.

The use of Compound-specific Stable Isotope Analysis (CSIA) is increasing in many areas of science and technology for source allocation, authentication, and characterization of transformation reactions. Until now, there have been no textbooks available for students with an analytical chemical background or basic introductory books emphasising the instrumentation and theory. This book is the first to focus solely on stable isotope analysis of individual compounds in sometimes complex mixtures. It acts as both a lecture companion for students and a consultant for advanced scientists in fields including forensic and environmental science. The book starts with a brief history of the field before going on to explain stable isotopes from scratch. The different ways to express isotope abundances are introduced together with isotope effects and isotopic fractionation. A detailed account of the required technical equipment and general procedures for CSIA is provided. This includes sections on derivatization and the use of microextraction techniques in GC-IRMS. The very important topic of referencing and calibration in CSIA is clearly described. This differs from approaches used in quantitative analysis and is often difficult for the newcomer to comprehend. Examples of successful applications of CSIA in food authenticity, forensics, archaeology, doping control, environmental science, and extraterrestrial materials are included. Applications in isotope data treatment and presentation are also discussed and emphasis is placed on the general conclusions that can be drawn from the uses of CSIA. Further instrumental developments in the field are highlighted and selected experiments are introduced that may act as a basis for a short practical course at graduate level.

The binding of small ligands to biological molecules is central to most aspects of biological function. The past twenty years has seen the development of an increasing armoury of biophysical methods that not only detect such binding, but also provide varying degrees of information about the kinetics, thermodynamics and structural aspects of the process. These methods have received increasing attention with the growth in more rational approaches to drug discovery and design. This book reviews the latest advances in the application of biophysics to the study of ligand binding. It provides a complete overview of current techniques to identify ligands, characterise their binding sites and understand their binding mechanisms. Particular emphasis is given to the combined use of different techniques and their relative strengths and weaknesses. Consistency in the way each technique is described makes it easy for readers to select the most suitable protocol for their research. The introduction explains why some techniques are more suitable than others and emphasizes the possible synergies between them. The following chapters, all written by a specialist in the particular technique, focus on each method individually. The book finishes by describing how several complimentary techniques can be used together for maximum effectiveness. This book is suitable for biomolecular scientists at graduate or post-doctoral level in academia and industry. Biologists and chemists will also find it a useful introduction to the techniques available.

Major technology shifts do not happen overnight and rarely are they the result of a single breakthrough discovery. Nowhere is this more true than for the broad set of enabling technologies that we have come to simply call "nanotechnology". Rather than standing on the shoulders of a few intellectual giants, nanotechnologies are created by tens of thousands of researchers and scientists working on minute and sometimes arcane aspects of their fields of expertise in areas as diverse as medicine, telecommunications, solar cells, filtration, coatings, or ever smaller transistors for electronic devices. They come from different sciences, live in different parts of the world and work for different organizations (government laboratories, industry laboratories, universities, private research facilities) and follow their own set of rules - get papers reviewed and published; achieve scientific recognition from their peers; struggle to get funding for new ideas; look to make that breakthrough discovery that leads to the ultimate resumÚ item - a nobel prize; get pushed by their funders to secure patent rights and commercialize new discoveries. This book puts a spotlight on some of the scientists who are pushing the boundaries of technology and it gives examples of their work and how they are advancing knowledge one little step at a time. The book shatters the monolithic term "nanotechnology" into the myriad of facets that it really is. It is a journey through the world of nanotechnology research and development, taking a personal look at how nanotechnologies get created today and by whom. The book covers 122 specific research projects that are happening in laboratories around the world and provides commentaries from the scientists in their own words. However, the collection of stories in this book barely scratches the surface of the vast and growing body of research that leads us into the nanotechnology age. The selection presented in the book is not meant to rank some laboratories and scientists higher than others, nor to imply that the work introduced in the book is more important or valuable than all the work that is not covered. The intention is to give the interested reader an idea of the incredibly diverse aspects that make up nanotechnology research and development - the results of which will bring about a new era of industrial and medical technologies. Nanoscience and nanotechnology research is a truly multidisciplinary and international effort. Each of the chapters is based on a particular scientific paper that has been published in a peer-reviewed journal and, while each story revolves around one or two scientists who were interviewed for this book, many, if not most, of the scientific accomplishments covered in the book are the result of collaborative efforts by several scientists and research groups, often from different organizations and from different countries. The book is different to other books in this field because it provides a novel human touch to nanotechnology research by not only covering a wide range of research topics but also the (often nameless) scientists behind this research. The book is a collection of Spotlight articles from the popular Nanowerk website and each article has been crafted with the author(s) of a scientific paper and signed off by them prior to being posted on Nanowerk. The book is intended for two broad groups of audiences - scientists and nanoscience students who want a bite-size, quick read to get a good first impression of what nanotechnologies are about and how they affect not only their own field but also neighbouring fields and other scientific disciplines further away. And a non-scientific readership that needs to (because it affects their organization and they have to acquaint themselves with nanotechnology) or wants to get a 'non-threatening' (i.e. no formulas, complex diagrams, or unexplained scientific terms) introduction, written by a non-scientist for non-scientists.

Mass spectrometry is one of the most versatile analytical techniques due to the vast range of analytes that it can detect and quantify and, as such, for its contribution to a significant number of life science fields. The legal and forensics community has certainly benefited from this technique, which has been able to provide reliable evidence in court cases. Liquid Chromatography/Gas Chromatography–Mass Spectrometry (LC/GC–MS) still have a dominant role in the provision of forensic intelligence. However, in the past decade new and exciting MS-based techniques have emerged and are or have evolved to be at an operational deployment maturity, enabling either fast, ambient, non-destructive, or portable screening (or encompass all of these features). In this book, developments of LC–MS and GC–MS based techniques are covered with respect to operational practice and new applications, accompanied by other MS-based techniques that are increasing forensic opportunities and that operate on a variety of evidence types. Whilst the underpinning working principles of each relevant mass spectrometry technique are summarised, each chapter primarily focuses on its implementation in criminal investigation and court cases. In the last chapters, this book additionally covers emerging MS technologies that are at the beginning of their operational implementation journey as well as niche applications outside the fields of traditional forensic science but with a clear potential to impact future investigations (forensics beyond the courtroom). This book provides an up-to-date reference for the mass spectrometry-based tools that are currently available both as established and as emerging methods within forensic practice. It will help casework commissioning managers and forensic providers worldwide to make more informed decisions as to the forensic strategy and workflow when examining exhibits. It is also recommended to postgraduates and early career investigators with reference to the contribution that these techniques and methods could make if applied to classic forensic science practice.

The agri-food industry creates a vast amount of waste each year. This is not just a problem for waste management, in terms of finding space to store waste and preventing escape of harmful waste into the environment; it also represents a loss of resources: the chemicals and energy which have gone into the production of this waste. If current waste streams can be converted into useful resources this will have multiple benefits by reducing the amount of waste sent to landfill or similar, reducing the need for other feedstocks and removing the pressure from feedstocks that could be used as food. Research into the different types of waste produced by the agri-food industry and approaches to converting them into useful chemicals or chemical feedstocks has advanced rapidly over the last few years. Covering the latest developments in the valorisation of food and agricultural waste, such as valorisation of citrus peel and industrial wastes, this book is a great resource for researchers interested in waste management, sustainability and the circular economy.

Corrosion affects every industry in which metal is involved, from manufacturing machinery to transport pipelines, and it is estimated to cost the global economy trillions of dollars per year. Many of the traditional methods for inhibiting corrosion are highly toxic (such as hexavalent chromium) or do not degrade readily in the environment (such as Benzotriazole) meaning they pose a risk to human and environmental health. Much recent work in the area has gone into searching for greener alternatives that will be both safe and effective. Beginning with a look at the fundamentals of corrosion inhibition and an explanation of the concepts of green chemistry, this book discusses various types of chemical that have been tested for their potential as greener corrosion inhibitors with reference to industrial applications. Green Corrosion Inhibition is a valuable reference for chemists and chemical engineers working in both research and design and academia who want to learn more about green corrosion inhibitors, their synthesis, design, and industrial scale applications.

In a classical kinetic resolution, two enantiomers of a racemate are transformed into chiral products at different rates with a maximum theoretical yield of 50%. However, the need to reduce costs and waste in synthesis have led to efforts to develop novel resolution procedures proceeding beyond this 50% limited yield. This has led to the evolution of classical kinetic resolution into dynamic kinetic resolution (DKR), allowing a quantitative yield of one of the enantiomers. DKR combines the resolution step of kinetic resolution with an in-situ racemization of the chirally-labile substrate. It is only in the last two decades that chiral green organocatalysts have been demonstrated to be capable of promoting DKRs considerably expanding the synthetic scope of the powerful concept of DKR. Collecting all the developments in the field of DKR, this book shows that a wide variety of organocatalysts allow excellent levels of stereocontrol and yields in many types of transformations. It is a great resource for academics and industrialists interested in green enantioselective catalytic reactions.
