Aqueous Systems at Elevated Temperatures and Pressures

Physical Chemistry in Water, Steam and Hydrothermal Solutions

 

Academic Press, 2004.

ISBNs 9780125444613

Colección: ScienceDirect

Resumen (en inglés): The International Association for the Properties of Water and Steam (IAPWS) has produced this book in order to provide an accessible, up-to-date overview of important aspects of the physical chemistry of aqueous systems at high temperatures and pressures. These systems are central to many areas of scientific study and industrial application, including electric power generation, industrial steam systems, hydrothermal processing of materials, geochemistry, and environmental applications. The authors’ goal is to present the material at a level that serves both the graduate student seeking to learn the state of the art, and also the industrial engineer or chemist seeking to develop additional expertise or to find the data needed to solve a specific problem.


The wide range of people for whom this topic is important provides a challenge. Advanced work in this area is distributed among physical chemists, chemical engineers, geochemists, and other specialists, who may not be aware of parallel work by those outside their own specialty. The particular aspects of high-temperature aqueous physical chemistry of interest to one industry may be irrelevant to another; yet another industry might need the same basic information but in a very different form.


To serve all these constituencies, the book includes several chapters that cover the foundational thermophysical properties (such as gas solubility, phase behavior, thermodynamic properties of solutes, and transport properties) that are of interest across numerous applications. The presentation of these topics is intended to be accessible to readers from a variety of backgrounds. Other chapters address fundamental areas of more specialized interest, such as critical phenomena and molecular-level solution structure. Several chapters are more application-oriented, addressing areas such as power-cycle chemistry and hydrothermal synthesis. As befits the variety of interests addressed, some chapters provide more theoretical guidance while others, such as those on acid/base equilibria and the solubilities of metal oxides and hydroxides, emphasize experimental techniques and data analysis.

- Covers both the theory and applications of all Hydrothermal solutions
- Provides an accessible, up-to-date overview of important aspects of the physical chemistry of aqueous systems at high temperatures and pressures
- The presentation of the book is understandable to readers from a variety of backgrounds

Aspects of Explosives Detection

 

Elsevier, 2009.

ISBNs 9780123745330

Colección: ScienceDirect

Resumen (en inglés): Detection and quantification of trace chemicals is a major thrust of analytical chemistry. In recent years much effort has been spent developing detection systems for priority pollutants. Less mature are the detections of substances of interest to law enforcement and security personnel:in particular explosives. This volume will discuss the detection of these, not only setting out the theoretical fundamentals, but also emphasizing the remarkable developments in the last decade. Terrorist events—airplanes blown out of the sky (PanAm 103 over Lockerbie) and attacks on U.S. and European cities (Trade Center in New York and the Murrah Federal Building in Oklahoma City, railways in London and Madrid)--emphasize the danger of concealed explosives. However, since most explosives release little vapor, it was not possible to detect them by technology used on most organic substances. After PanAm 103 was downed over Scotland, the U.S. Congress requested automatic explosive detection equipment be placed in airports. This volume outlines the history of explosive detection research, the developments along the way, present day technologies, and what we think the future holds.
- Written by experts in the field who set out both the scientific issues and the practical context with authority
- Discusses and describes the threat
- Describes the theoretical background and practical applications of both trace and bulk explosives detection

Bioactive Lipids

 

Woodhead Publishing, 2004.

ISBNs 9780953194971

Colección: ScienceDirect

Resumen (en inglés): In Bioactive lipids, Anna Nicolaou and George Kokotos have brought together an international team of authors to discuss the nomenclature, structures, biochemistry, pharmacology and recent developments in the main classes of bioactive lipids. These lipids are essential components of the cell membrane and play many dynamic roles in mediating and controlling a wide array of cellular activities including membrane structure and organization, metabolic and gene regulation, protein structure and function, energy production, and signalling pathways.

The lipid interests of scientists in the pharmaceutical and food industries are converging as the broader significance of bioactive lipids is increasingly recognized. Lipids and lipid-metabolizing enzymes are targeted for the development of new drugs. Meanwhile, functional foods, nutraceuticals and supplements already have lipids as major active ingredients. The food industry will progress from simply using lipids as ingredients, to the formulation of products that influence the synthesis, metabolism and effects of bioactive lipids in the body. These advances in applied lipid biochemistry will build on the fundamental research of lipid scientists in universities worldwide, such as those scientists contributing to Bioactive lipids.
