Experts from both academia and industry provide an overview of current research in computer-assisted analytical spectroscopy and chemometrics.
Basic Training in Chemistry is unique in that it gathers into one source the essential information that is usually widely dispersed. This book can be used as a quick reference guide to the different disciplines of Chemistry: the areas covered are General, Inorganic, Organic, and Instrumental Analysis. Although comprehensive in nature, Basic Training in Chemistry is not meant to replace any standard textbook but rather to be a supplement or additional source of information, or even a comprehensive review guide. Basic Training in Chemistry is a useful addition to any academic or commercial laboratory setting where access to a wide variety of information is needed. The book can be an exceptional source of information for the undergraduate or graduate student as well as for the experienced chemist. Anyone needing a single source of information covering several different disciplines will find this book to be an excellent addition to their usual references.
Prof. Jerzy Sobkowski starts off this 31st volume of Modern Aspects of Electrochemistry with a far-ranging discussion of experimental results from the past 10 years of interfacial studies. It forms a good background for the two succeeding chapters. The second chapter is by S. U. M. Khan on quantum mechanical treatment of electrode processes. Dr. Khan's experience in this area is a good basis for this chapter, the contents of which will surprise some, but which as been well refereed. Molecular dynamic simulation is now a much-used technique in physical electrochemistry and in the third chapter Ilan Benjamin has written an account that brings together information from many recent publications, sometimes confirming earlier modeling approaches and sometimes breaking new territory. In Chapter 4, Akiko Aramata's experience in researching single crystals is put to good advantage in her authoritative article on under- tential deposition. Finally, in Chapter 5, the applied side of electrochemistry is served by Bech-Neilsen et al. in the review of recent techniques for automated measurement of corrosion. J. O'M.

The Ebro is a typical Mediterranean river characterized by seasonal low flows and extreme flush effects, with important agricultural and industrial activity that has caused heavy contamination problems. This volume deals with soil-sediment-groundwater related issues in the Ebro river basin and summarizes the results generated within the European Union-funded project "AquaTerra." The following topics are highlighted: Hydrology and sediment transport and their alterations due to climate change, aquatic and riparian biodiversity in the Ebro watershed, occurrence and distribution of a wide range of priority and emerging contaminants, effects of chemical pollution on biota and integration of climate change scenarios with several aspects of the Ebro s hydrology and potential impacts of climate change on pollution. The primary objective of the book is to lay the foundation for a better understanding of the behavior of environmental pollutants and their fluxes with respect to climate and land use changes."
Biological membranes play a central role in cell structure, shape and functions. However, investigating the membrane bilayer has proved to be difficult due to its highly dynamic and anisotropic structure, which generates steep gradients at the nanometer scale. Due to the decisive impact of recently developed fluorescence-based techniques, tremendous advances have been made in the last few years in our understanding of membrane characteristics and functions. In this context, the present book illustrates some of these major advances by collecting review articles written by highly respected experts. The book is organized in three parts, the first of which deals with membrane probes and model membranes. The second part describes the use of advanced quantitative and high-resolution techniques to explore the properties of biological membranes, illustrating the key progress made regarding membrane organization, dynamics and interactions. The third part is focused on the investigation of membrane proteins using the same techniques, and notably on the membrane receptors that play a central role in signaling pathways and therapeutic strategies. All chapters provide comprehensive information on membranes and their exploration for beginners in the field and advanced researchers alike.
'There is no higher or lower knowledge, but only one, flowing out of experimen tation. ' (Leonardo da Vinci, 1452-1519) Food materials are complex in terms of composition, structure and mechanical properties. In order to understand the relationship between these different kinds of complexity, the experimental food scientist has a wide range of physico-chemical techniques at his or her disposal. But, in practice, of course, there are often severe limitations on the techniques which are available for any particular investigation. Apart from obvious constraints associated with instrument cost and accessibility, one com mon problem is a lack of knowledge by the non-expert about the capabilities and limitations of every new advance in instrumentation. No individual worker in the field of food science can become expert in more than a very small number of experimental techniques. On the other hand, most of us wish to know enough about the major emerging experimental technologies to enable us to make a realistic assessment of what they may have to contribute towards any new problems that we may meet. This book collects together in a single volume an up-to-date set of introductory articles describing a range of new physico-chemical tech niques which can be used to probe food structure at the molecular, colloidal and microscopic levels. Each individual chapter is written by an acknowledged expert in his field.

Take any combination of the following features: supramolecular structures with a specific fluorescent probe localized as you would like; nanoscale spatial reso- tion; tailor-made molecular and/or solid-state fluorescing nanostructures; us- friendly and/or high- throughput fluorescence techniques; the ability to do wh- ever you wish with just one single (supra)molecule; utilization of non-linear optical processes; and,last but not least,physical understanding of the processes resu- ing in a (biological) functionality at the single molecule level. What you will then have is some recent progress in physics,chemistry,and the life sciences leading to the development of a new tool for research and application. This was amply demonstrated at the 8th Conference on Methods and Applications of Fluorescence: Probes,Imaging,and Spectroscopy held in Prague,the Czech Republic on August 24th-28th, 2003. This formed a crossroad of ideas from a variety of natural science and technical research fields and biomedical applications in particular. This volume - the third book in the Springer-Verlag Series on Fluorescence - reviews some of the most characteristic topics of the multidisciplinary area of fluorescence applications in life sciences either presendted directly at th 8th MAF Conference or considered to be a cruical development in the field. In the initial contribution in Part 1 - Basics and Advanced Approaches,the - itors explain the basics of fluorescence and illustrate the relationship between some modern fluorescence techniques and classical approaches.

A Practical Guide to Understanding the NMR of Polymers presents an introduction to the theory and practice of NMR, and includes sections on the fundamental principles of NMR and the applications to polymers. This book will help readers understand how these methods can be used to determine the chemical structure of polymers that influences the macroscopic properties. Solid state NMR methods are introduced to enable the readers to measure the structure of polymers on longer length scales. It is also shown how NMR is used to measure the molecular dynamics that can be related to the mechanical properties of polymers.
Stability constants are fundamental to understanding the behavior of metal ions in aqueous solution. Such understanding is important in a wide variety of areas, such as metal ions in biology, biomedical applications, metal ions in the environment, extraction metallurgy, food chemistry, and metal ions in many industrial processes. In spite of this importance, it appears that many inorganic chemists have lost an appreciation for the importance of stability constants, and the thermodynamic aspects of complex formation, with attention focused over the last thirty years on newer areas, such as organometallic chemistry. This book is an attempt to show the richness of chemistry that can be revealed by stability constants, when measured as part of an overall strategy aimed at understanding the complexing properties of a particular ligand or metal ion. Thus, for example, there are numerous crystal structures of the Li+ ion with crown ethers. What do these indicate to us about the chemistry of Li+ with crown ethers? In fact, most of these crystal structures are in a sense misleading, in that the Li+ ion forms no complexes, or at best very weak complexes, with familiar crown ethers such as l2-crown-4, in any known solvent. Thus, without the stability constants, our understanding of the chemistry of a metal ion with any particular ligand must be regarded as incomplete. In this book we attempt to show how stability constants can reveal factors in ligand design which could not readily be deduced from any other physical technique.
This book offers an overview of state-of-the-art in non amplified DNA detection methods and provides chemists, biochemists, biotechnologists and material scientists with an introduction to these methods. In fact all these fields have dedicated resources to the problem of nucleic acid detection, each contributing with their own specific methods and concepts. This book will explain the basic principles of the different non amplified DNA detection methods available, highlighting their respective advantages and limitations. Non-amplified DNA detection can be achieved by adopting different techniques. Such techniques have allowed the commercialization of innovative platforms for DNA detection that are expected to break into the DNA diagnostics market. The enhanced sensitivity required for the detection of non amplified genomic DNA has prompted new strategies that can achieve ultrasensitivity by combining specific materials with specific detection tools. Advanced materials play multiple roles in ultrasensitive detection. Optical and electrochemical detection tools are among the most widely investigated to analyze non amplified nucleic acids. Biosensors based on piezoelectric crystal have been also used to detect unamplified genomic DNA. The main scientific topics related to DNA diagnostics are discussed by an outstanding set of authors with proven experience in this field.
From the global to the cellular level, oxidants have provided the chemical dynamic for reactions both harmful and benign. As varied in type as in effect, oxidants include the oxides of nitrogen, sulfur, and carbon - implicated in the generation of smog - as well as oxidants useful in hypoxic cell-specific anticancer drugs and the treatment of contaminated waters. The complex nature of oxidants as well as their pervasiveness in the environment have made them keenly interesting to scientists monitoring environmental hazards and human health. Environmental Oxidants is a broad-based, multidisciplinary study of the environmental chemistry and toxicology of oxidants as well as their widening role in pollution control. Featuring up-to-date research from internationally renowned scientists, the book sheds light on such critical topics as the evolution, production, distribution, and fate of oxidants in the atmosphere, hydrosphere, and biosphere; the influence of human activities on oxidative processes in the atmosphere; oxidative stress at the cellular, systemic, and ecosystem levels; and the use of oxidants to remediate polluted sites. Specific studies include photosynthetic oxygen evolution, oxidants in the unpolluted marine atmosphere, ozone formation in urban plumes, the impact of dynamics and transport on stratospheric ozone and other constituents, health effects and toxicology of ozone and nitrogen dioxide, and some hematological effects of oxidants. Reflecting current health concerns, the book also addresses such timely issues as oxidative stress and asbestos, the role of oxygen in lung toxicity induced by mineral fibers and particulates, as well as an alternative attainment criteria fora secondary federal standard for ozone. A selective and incisive look at the current state of research on oxidants, Environmental Oxidants provides environmental scientists and engineers with an informative, detailed discussion of just how and why oxidants have emerged as a key issue in human health and environmental integrity.
This is the ?fth volume in the Reviews in Fluorescence series. To date, four previous volumes have been both published and well received by the scienti?c community. Several book reviews in the last few years have also favorably remarked on the series. In this ?fth volume we continue the tradition of publishing leading edge and timely articles from authors around the world.

Now and in the future, the ever-growing demand for drinking water will lead many cities to implement indirect water reuse programs, where wastewater effluent becomes part of the drinking water sources. Pollution of those sources with emerging contaminants (micropollutants) such as endocrine disrupting compounds, pharmaceutically active compounds, pesticides and personal care products is a fact known worldwide. In this thesis, nanofiltration (NF) and reverse osmosis (RO) are demonstrated to be appropriate technologies for removing a large number of micropollutants; however, the performance of NF and RO can be questioned because there are limited tools that optimise quantification of the removal of contaminants. Therefore, in this thesis, by means of the use of multivariate data analysis techniques, removal quantification is effectively determined and more understanding of the separation of micropollutants by membranes is achieved.

This volume provides an overview of the determinants of the release of and exposure to airborne nanoparticles. Whether intentionally manufactured or unintentionally generated during industrial processes, the release of nanoparticles can result in significant worker exposure, which must be dealt with adequately by means of dedicated risk assessments to ensure workplace health and safety. The book extensively discusses a number of measurement and modelling strategies available for this purpose. It also reviews the health hazardous potential of nano-sized particles and fibres, and follows the flow of engineered nanomaterials from production and use to disposal and the environment. It appeals to a wide readership, from specialists already working in the field to newcomers aiming to gain insights into this topic.
Spectrophotometry enables one to determine, with good precision and
sensitivity, almost all the elements present in small and trace
quantities of any material. The method is particularly useful in
the determination of non-metals and allows the determination
elements in a large range of concentrations (from single % to low
ppm levels) in various materials. In "Separation, Preconcentration and Spectrophotometry in
Inorganic Analysis," much attention has been paid to separation and
preconcentration methods, since they play an essential role in
increasing the selectivity and sensitivity of spectrophotometric
methods. Separation and preconcentration methods have also been
utilised in other determination techniques. Spectrophotometric methods which are widely used for the
determination of the elements in a large variety of inorganic
materials are presented in the book whilst separation and
preconcentration procedures combined with spectrophotometry are
also described. This book contains recent advances in spectrophotometry,
detailed discussion of the instrumentation, and the techniques and
reagents used for spectrophotometric determination of elements in a
wide range of materials as well as a detailed discussion of
separation and preconcentration procedures that precede the
spectrophotometric detection.
For the first time, distinguished scientists from key institutions worldwide provide a comprehensive approach to optical sensing techniques employing the phenomenon of guided wave propagation for chemical and biosensors. This includes both state-of the-art fundamentals and innovative applications of these techniques. The authors present a deep analysis of their particular subjects in a way to address the needs of novice researchers such as graduate students and post-doctoral scholars as well as of established researchers seeking new avenues. Researchers and practitioners who need a solid foundation or reference will find this work invaluable. This second of two volumes covers the incorporation of periodic structures in waveguides to exploit the Bragg phenomenon, optical fiber sensors, hollow waveguides and micro-resonators as well as a review of the tremendous expansion of terahertz technology for sensing applications.
Analytical ultracentrifugation (AUC) is a powerful method for the characterization of polymers, biopolymers, polyelectrolytes, nanoparticles, dispersions, and other colloidal systems. The method is able to determine the molar mass, the particle size, the particle density and interaction parameters like virial coefficients and association constants. Because AUC is also a fractionation method, the determination of the molar mass distribution, the particle size distribution, and the particle density distribution is possible. A special technique, the density gradient method, allows fractionating heterogeneous samples according to their chemical nature that means being able to detect chemical heterogeneity. The book is divided into chapters concerning instrumentation, sedimentation velocity runs, density gradient runs, application examples and future developments. In particular, the detailed application chapter demonstrates the versatility and power of AUC by means of many interesting and important industrial examples. Thus the book concentrates on practical aspects rather than details of centrifugation theory. Both authors have many years of experience in an industrial AUC research laboratory of a world leading chemical company.
