This book provides basic coverage of the fundamentals and principles of green chemistry as it applies to chemical analysis. The main goal of "Green Analytical Chemistry" is to avoid or reduce the undesirable environmental side effects of chemical analysis, while preserving the classic analytical parameters of accuracy, sensitivity, selectivity, and precision. The authors review the main strategies for greening analytical methods, concentrating on minimizing sample preparation and handling, reducing solvent and reagent consumption, reducing energy consumption, minimizing of waste, operator safety and the economic savings that this approach offers. Suggestions are made to educators and editors to standardize
terminology in order to facilitate the identification of analytical
studies on green alternatives in the literature because there is
not a wide and generalized use of a common term that can group
efforts to prevent waste, avoid the use of potentially toxic
reagents or solvents and those involving the decontamination of
wastes.

Chemoinformatics and Bioinformatics in the Pharmaceutical Sciences brings together two very important fields in pharmaceutical sciences that have been mostly seen as diverging from each other: chemoinformatics and bioinformatics. As developing drugs is an expensive and lengthy process, technology can improve the cost, efficiency and speed at which new drugs can be discovered and tested. This book presents some of the growing advancements of technology in the field of drug development and how the computational approaches explained here can reduce the financial and experimental burden of the drug discovery process. This book will be useful to pharmaceutical science researchers and students who need basic knowledge of computational techniques relevant to their projects. Bioscientists, bioinformaticians, computational scientists, and other stakeholders from industry and academia will also find this book helpful.
Pyrolysis of Organic Molecules with Applications to Health and
Environmental Issues, the 28th volume in the Techniques and
Instrumentation in Analytical Chemistry series, gives a systematic
and comprehensive description of pyrolysis of non-polymeric organic
molecules. Pyrolysis is involved in many practical applications as
well as in many common human activities, but harmful compounds can
be generated in the process. The study of pyrolysis and of the
formation of undesirable compounds as a result of pyrolytic
processes is of considerable interest to chemists, chemical
engineers, and toxicologists.
Translational motion in solution, either diffusion or fluid flow, is at the heart of chemical and biochemical reactivity. Nuclear Magnetic Resonance (NMR) provides a powerful non-invasive technique for studying the phenomena using magnetic field gradient methods. Describing the physical basis of measurement techniques, with particular emphasis on diffusion, balancing theory with experimental observations and assuming little mathematical knowledge, this is a strong, yet accessible, introduction to the field. A detailed discussion of magnetic field gradient methods applied to Magnetic Resonance Imaging (MRI) is included, alongside extensive referencing throughout, providing a timely, definitive book to the subject, ideal for researchers in the fields of physics, chemistry and biology.

An additional chapter reviewing the PARACAT collaboration from the EU has also been included. Providing a snapshot of the area by a handpicked group of researchers at the cutting-edge of the field, this book is a useful addition to any library supporting this research.
This book crosses the boundary from exploration- and production-related chemistry to refining, from upstream through downstream. It discusses the composition of petroleum through the use of "petroleum molecular composition continuity model." .
ReAction gives a scientist's and artist's response to the dark and
bright sides of chemistry found in 140 films, most of them
contemporary Hollywood feature films but also a few documentaries,
shorts, silents, and international films.
This title includes a number of Open Access chapters. This collection presents a broad selection of recent research on analytical chemistry, including methods of determination and analysis as applied to plants, pharmaceuticals, foods, proteins, and more. Analytical chemistry is the study of what chemicals are present and in what amount in natural and artificial materials. Because these understandings are fundamental in just about every chemical inquiry, analytical chemistry is used to obtain information, ensure safety, and solve problems in many different chemical areas, and is essential in both theoretical and applied chemistry. Analytical chemistry is driven by new and improved instrumentation.
The aim of this volume is to present the basic mathematical aspects
of the ranking methods using a didactical approach and to explain
their use through examples of relevant applications in different
scientific fields. Ranking methods can be applied in several
different fileds, such as decision support, toxicology, EU priority
lists of toxic chemicals, environmental problems, proteomics and
genomics, analytical chemistry, food chemistry and QSAR.
Surface-Enhanced Raman Scattering (SERS) was discovered in the
1970s and has since grown enormously in breadth, depth, and
understanding. One of the major characteristics of SERS is its
interdisciplinary nature: it lies at the boundary between physics,
chemistry, colloid science, plasmonics, nanotechnology, and
biology. By their very nature, it is impossible to find a textbook
that will summarize the principles needed for SERS of these rather
dissimilar and disconnected topics. Although a basic understanding
of these topics is necessary for research projects in SERS with all
its many aspects and applications, they are seldom touched upon as
a coherent unit during most undergraduate studies in physics or
chemistry. This book intends to fill this existing gap in the
literature. It provides an overview of the underlying principles of
SERS, from the fundamental understanding of the effect to its
potential applications. It is aimed primarily at newcomers to the
field, graduate student, researcher or scientist, attracted by the
many applications of SERS and plasmonics or its basic science. The
emphasis is on concepts and background material for SERS, such as
Raman spectroscopy, the physics of plasmons, or colloid science,
all of them introduced within the context of SERS, and from where
the more specialised literature can be followed.
For almost a decade, quantitative NMR spectroscopy (qNMR) has been
established as valuable tool in drug analysis. In all disciplines,
i. e. drug identification, impurity profiling and assay, qNMR can
be utilized.

A classical metastable state possesses a local free energy minimum
at infinite sizes, but not a global one. This concept is phase size
independent. We have studied a number of experimental results and
proposed a new concept that there exists a wide range of metastable
states in polymers on different length scales where their
metastability is critically determined by the phase size and
dimensionality. Metastable states are also observed in phase
transformations that are kinetically impeded on the pathway to
thermodynamic equilibrium. This was illustrated in structural and
morphological investigations of crystallization and mesophase
transitions, liquid-liquid phase separation, vitrification and gel
formation, as well as combinations of these transformation
processes. The phase behaviours in polymers are thus dominated by
interlinks of metastable states on different length scales. This
concept successfully explains many experimental observations and
provides a new way to connect different aspects of polymer physics.

UV-Visible Spectrophotometry of Water and Wastewater is the first
book dedicated to the use of UV spectrophotometry for water and
wastewater quality monitoring. Using practical examples the reader
is shown how this technique can be a source of new methods of
characterization and measurement. Easy and fast to run, this simple
and robust analytical technique must be considered as one of the
best ways to obtain a quantitative estimation of specific or
aggregate parameters (eg. Nitrate, TOC), and simultaneously
qualitative information on the global composition of water and its
variation.
