Antimony, arsenic, bismuth, germanium, lead, selenium, tellurium and tin just some of the elements which, in trace amounts, have biological, environmental and technological importance. Hydride Generation Atomic Absorption Spectrometry describes one of the most accurate analytical techniques for trace analysis of these elements, sensitive to picogram levels. Over the last decade, significant instrumental and methodological progress has led to HG-AAS being widely applied to an extensive range of sample types. In this first comprehensive monograph on HG-AAS, the authors treat both theoretical and experimental aspects of the subject in a critical and in-depth manner. Hydride Generation Atomic Absorption Spectrometry is divided into two parts, with the theoretical background and experimental approach covered in Part I. Part II discusses the methodology and analytical applications to a wide range of fields, arranged in an easy to use element-by-element format. Over 1500 references provide an exhaustive coverage of the vast literature on HG-AAS, making Hydride Generation Atomic Absorption Spectrometry the premier reference source on this important technique. Hydride Generation Atomic Absorption Spectrometry will be an invaluable reference work for all analysts using hydride generation for AAS or for other spectrometric methods.

Stability is one of the most important performances required for silver halide photographic materials. In 1935, Dr. E. 1. Birr introduced the concept of the stabilization ofphotographic emulsions for the first time by inventing a most effective stabilizer, 4-oxo-6-methyl-l,3,3a,7-tetraazaindene (TAl). Dr. Birr's monograph Stabilization ofPhotographic Silver Halide Emulsions was published in 1974, and accepted as a reliable reference book by many photographic scientists and engineers. Since then, silver halide photographic materials have been greatly improved and expanded through active and continual development of various kinds of technologies. Especially, extensive efforts have been made to develop photographic materials with high sensitivity and rapid processing, which rely upon the stability ofphotographic emulsions under various conditions. Thus, the concept and technologies of stabilization ofphotographic silver halide materials have been expanded so extensively that many photographic scientists and engineers eagerly want a reliable, new reference book on the stabilization of photographic emulsions. Dr. Gunther Fischer is one of the most experienced and eminent scientists and engineers in the field of the stabilization of photographic materials with expanded concept. He has been involved in research on the stabilization of pho tographic emulsions since 1964 when he joined the Technical Scientific Laboratory in the Research and Development Department of the Photo Film Company Agfa Wolfen formerly headed by Dr. Birr, whom he succeeded in that position. I was deeply impressed by his fruitful and elaborate achievements in these fields."

The physical sciences and mathematics are extraordinarily useful in explaining the material world. People and society are constrained by physical reality, but we are often unclear on what constraints are absolute, which may be relative, and those that are simply a matter of taste. Bandwidth explains how limitations in the movement and perception of information constrain human behavior, cognition, interaction, and perspective. How fast can we learn? How much? Why are habits and biases unavoidable? Why is the common statement 'any nation that can land people on the moon surely can ...' frequently wrong? Using equations and physical models, Bandwidth describes constraints which, in part, explain political, economic, religious, and personal frictions. Aspects considered include: how much information can one human absorb in a lifetime? How far does a process of perturbation propagate? How do specialization or generalization, critical thinking or belief, influence what people accomplish? Throughout, equations are used to compactly express ideas, illustrating why mathematical economy of expression accelerates communication and deeper understanding. The critical impacts of uncertainty, fluctuations, or noise, and their implications for law and society, are emphasized.

A complete guide to choosing and using the best analytical technique for the job at hand

Today's new generation of spectroscopic instrumentation allows for more accurate and varied measurements than ever before. At the same time, increasingly powerful, user-friendly PC hardware and software make running those instruments relative child's play. However, although they may have solved many of the problems traditionally associated with conducting molecular spectroscopic analyses, these refinements tend to obscure inherent technical challenges which, if not taken into consideration, can seriously undermine a research initiative. Modern Techniques in Applied Molecular Spectroscopy gives scientists and technicians the knowledge they need to address those challenges and to make optimal selection and use of contemporary molecular spectroscopic techniques and technologies.

Resolving Spectral Mixtures: With Applications from Ultrafast Time-Resolved Spectroscopy to Superresolution Imaging offers a comprehensive look into the most important models and frameworks essential to resolving the spectral unmixing problem-from multivariate curve resolution and multi-way analysis to Bayesian positive source separation and nonlinear unmixing. Unravelling total spectral data into the contributions from individual unknown components with limited prior information is a complex problem that has attracted continuous interest for almost four decades. Spectral unmixing is a topic of interest in statistics, chemometrics, signal processing, and image analysis. For decades, researchers from these fields were often unaware of the work in other disciplines due to their different scientific and technical backgrounds and interest in different objects or samples. This led to the development of quite different approaches to solving the same problem. This multi-authored book will bridge the gap between disciplines with contributions from a number of well-known and strongly active chemometric and signal processing research groups. Among chemists, multivariate curve resolution methods are preferred to extract information about the nature, amount, and location in time (process) and space (imaging and microscopy) of chemical constituents in complex samples. In signal processing, assumptions are usually around statistical independence of the extracted components. However, the chapters include the complexity of the spectral data to be unmixed as well as dimensionality and size of the data sets. Advanced spectroscopy is the key thread linking the different chapters. Applications cover a large part of the electromagnetic spectrum. Time-resolution ranges from femtosecond to second in process spectroscopy and spatial resolution covers the submicronic to macroscopic scale in hyperspectral imaging.

This book addresses the basic understanding of food contaminants and their sources, followed by the techniques to measure food safety and quality. It is divided into four parts: Part A - sources of contaminants in foods, their associated health risks, and integrated management and alternative options to minimize contaminants; Part B - Technological assessment of conventional methods and selected advanced methods for the detection, identification and enumeration of microbial contaminates; Part C - Technological assessment of different chemical measurements techniques; and Part D - Technological assessment of different instrumental techniques to assess sensory properties of foods. Food safety is a growing concern due to the increase in food-borne illnesses caused by food adulteration, excessive use of pesticides, use of chemical preservatives and artificial fruit ripening agents, microbial contaminations, and improper food handling. Chemical contaminants in food could be transferred from environmental or agrochemical sources, personal care products, and other by-products of water disinfects. In addition, microbial food safety can be threatened due to the presence of many pathogens, such as Salmonella, Escherichia coli, Clostridium botulinum, Staphylococcus aureus, and Listeria monocytogenes in foods. Globally, strict regulations are imposed to limit the potential contaminants in foods. Development of accurate, rapid, and inexpensive approaches to test food contamination and adulteration would be highly valued to ensure global food safety. There are existing processes to ensure safety of food products from chemical and microbial contaminants. Apart from the existing measurement technologies, varieties of new techniques are also being emerged and these could be potential to ensure food safety and quality. In addition to chemical and microbial properties, sensory properties such as texture, mouth feel, flavor, and taste, are among the most important attributes of food products to ensure their acceptability by consumers. Two approaches are available to evaluate sensory properties of food products, namely subjective and objective analyses. The responses are perceived by all five senses: smell, taste, sight, touch, and hearing. The approach used in sensory evaluation varies depending on the types of foods and the ultimate goal of the testing. Sensory attributes are the most important quality parameters after ensuring the safety of foods.
