Six years after the symposium on "Stability and Stabilization of Enzymes," a second symposium, "Stability and Stabilization of Biocatalysts," on which this book is based, was organized. At the symposium, 210 participants representing all continents came together to learn from 150 oral and poster communications.

The volume brings up-to-date the work already going on, and identifies possible breakthroughs in the research.
This timely book therefore presents cutting edge developments in topics such as non-covalent processes in solution, protein engineering and thermophile enzymes, immobilized enzymes, non-conventional media, and whole cells.
An excellent addition to the available literature, it will make a useful contribution to this key area of applied biocatalysis.

OSHA (29 CFR 1910.119) has recognized AIChE/DIERS two-phase flow publications as examples of "good engineering practice" for process safety management of highly hazardous materials. The prediction of when two-phase flow venting will occur, and the applicability of various sizing methods for two-phase vapor-liquid flashing flow, is of particular interest when designing emergency relief systems to handle runaway reactions. This comprehensive sourcebook brings together a wealth of information on methods that can be used to safely size emergency relief systems for two-phase vapor-liquid flow for flashing or frozen, viscous or nonviscous fluids. Design methodologies are illustrated by selected sample problems. Written by industrial experts in the safety field, this book will be invaluable to those charged with operating, designing, or managing today's and tomorrow's chemical process industry facilities.

Practical Dispersion A Guide to Understanding and Formulating Slurries Robert F. Conley This book is a practical guide to producing slurries more efficiently, intelligently, and economically. It provides hands--on knowledge of sufficient technical depth to allow those personnel involved in on--going dispersion practices to feel more proficient in making system modifications, as well as to meet the specific mechanical, chemical, environmental, and other requirements of their customers. To this end, a broad description of dispersants, their functions, and field applications has been provided. Dispersant activities are defined on the basis of solid and agent structures and affinities. This book is intended for technical personnel in the many industries involved with slurry processing either in materials production or application, and whose day--to--day activities lie in manufacturing such dispersed products as paints; pigment premixes; treated metallic, inorganic, and organic powders; food products; cosmetics; pharmaceuticals; and dyes and inks.

The main physicochemical aspects of foam and foam films such as preparation, structure, properties, are considered, giving a special emphasis on foam stability. It is shown that the foam and foam films are an efficient object in the study of various surface phenomena and in establishing regularities common for different interfaces, in particular, water/oil interface. The techniques and results on foam films have an independent meaning and involve the latest achievement in this field, with a focus on authors' results.

The book has an expressed monographic character. It reveals joint ideas, i.e. the quantitative approach in treating foams is based on foam film behaviour and the techniques for controlling the foam liquid content, developed by the authors. A major contribution represents the independent consideration of formation and stability of foam films in theoretical and experimental aspects. No monograph published so far reveals these topics in the mentioned manner. Data and information about foams, physicochemical characterization of surfactants, phospholipids and polymers can also be found. Furthermore, the book provides information about: techniques involved in the study of foam films and foam structure and properties; foam drainage; processes of destruction in gravitational and centrifugal fields; reasons for stability of films and their role in the processes running in the foam; mechanical, rheological, optical, thermophysical, electrical properties; foam destruction upon addition of antifoams (mechanism of destruction, techniques, application); scientific principles of controlling foam properties and their application in foam separation and concentration; enhanced oil recovery; thermodynamic and non-equilibrium properties of foam films, stabilized by surfactants, phospholipids and polymers; techniques for the study of surface forces; formation and stability of foam films; black films, including bilayers; new theories of stability of amphiphile bilayer; experiments involved in this stability; application in biology and medicine.

This newly designed and enlarged edition offers an up-to-date presentation of biosensor development and modeling from both a chemical and a mathematical point of view. An entire new chapter in particular is dedicated to optimal design of biosensors. Two more new chapters discuss biosensors which utilize microbial cells and are based on carbon nanotubes respectively. All the other chapters have been revised and updated. The book contains unique modeling methods for amperometric, potentiometric and optical biosensors based mainly on biocatalysts . It examines processes that occur in the sensors' layers and at their interface, and it provides analytical and numerical methods to solve equations of conjugated enzymatic (chemical) and diffusion processes. The action of single enzyme as well as polyenzyme biosensors and biosensors based on chemically modified electrodes is studied. The modeling of biosensors that contain perforated membranes and multipart mass transport profiles is critically investigated. Furthermore, it is fully described how signals can be biochemically amplified, how cascades of enzymatic substrate conversion are triggered, and how signals are processed via a chemometric approach and artificial neuronal networks. The results of digital modeling are compared with both proximal analytical solutions and experimental data.
