Compostable Polymer Materials deals with an environmentally important family of polymers. These compostable polymers are specially designed to be disposed of in industrial and municipal compost facilities after their useful lives. They are able to undergo degradation and leave no visible, distinguishable or toxic residue. Environmental concerns and legislative measures taken in different regions of the world make composting an increasingly attractive route for the disposal of redundant polymers.
This book provides up-to-date results and information about compostable polymer materials in a coherent and comprehensive manner. It covers the entire spectrum of preparation, properties, degradation, and environmental issues. The emphasis is on recent studies concerning compostability and ecotoxicological assessment of polymer materials--important issues from the ecological point of view. Moreover, the thermal behavior of compostable polymers is described. Their price evolution over the past decade, an estimation of the market and future perspectives are presented.
This book is aimed at polymer scientists and chemical engineers as well as scientists working in the fields of ecology and environmental science.

About the Book :-
Provides a comprehensive summary of the theoretical aspects of diffusion and mass transfer
Analyzes a wide variety of mass transfer problems
Explains and shows the use of solution methods such as Green’s functions, perturbation methods, and similarity transformations
Considers various aspects of polymer behavior, including polymer diffusion, sorption in polymers, and volumetric behavior of polymer–solvent systems
Discusses the free-volume theory for the prediction of self-diffusion coefficients for polymer–solvent systems
A proper understanding of diffusion and mass transfer theory is critical for obtaining correct solutions to many transport problems. Diffusion and Mass Transfer presents a comprehensive summary of the theoretical aspects of diffusion and mass transfer and applies that theory to obtain detailed solutions for a large number of important problems. Particular attention is paid to various aspects of polymer behavior, including polymer diffusion, sorption in polymers, and volumetric behavior of polymer–solvent systems.
The book first covers the five elements necessary to formulate and solve mass transfer problems, that is, conservation laws and field equations, boundary conditions, constitutive equations, parameters in constitutive equations, and mathematical methods that can be used to solve the partial differential equations commonly encountered in mass transfer problems. Jump balances, Green’s function solution methods, and the free-volume theory for the prediction of self-diffusion coefficients for polymer–solvent systems are among the topics covered. The authors then use those elements to analyze a wide variety of mass transfer problems, including bubble dissolution, polymer sorption and desorption, dispersion, impurity migration in plastic containers, and utilization of polymers in drug delivery. The text offers detailed solutions, along with some theoretical aspects, for numerous processes including viscoelastic diffusion, moving boundary problems, diffusion and reaction, membrane transport, wave behavior, sedimentation, drying of polymer films, and chromatography.
Presenting diffusion and mass transfer from both engineering and fundamental science perspectives, this book can be used as a text for a graduate-level course as well as a reference text for research in diffusion and mass transfer. The book includes mass transfer effects in polymers, which are very important in many industrial processes. The attention given to the proper setup of numerous problems along with the explanations and use of mathematical solution methods will help readers in properly analyzing mass transfer problems.

This timely book covers the most recent developments in the chemical detection of explosives in a variety of environments. Beginning with a broad view of the need for and the potential applications of chemical sensing, the book considers the issue of how to effectively include chemical sensing into systems designed to find hidden explosives devices. Offering a firsthand look at the latest technologies direct from those who are actively developing them, the book features:
• A look at the history of the field, including the contributions of recent programs
• A brief explanation of the chemistry of various explosives and differences in the behavior of their molecules as they are released from a source and migrate to a place where they may be detected
• An introduction to the problems presented by trace element sensing
• An overview and comparison of the technologies currently being used and developed
• Case studies of field experiences with chemical sensors
• A look at the emerging threat of non-traditional explosives
This book is an important reference for explosives engineers, systems engineers involved in the development of related devices, government agencies and NGOs involved in demining efforts, military and law enforcement specialists in mines and explosive ordinance disposal (EOD), as well as environmental scientists and chemists involved in explosives research.
In addition to providing field workers with knowledge that will help them decide where and how to search for explosives using chemical sensors. It will provide them with an understanding of the potential and the limitations of chemical sensing in their search for and identification of dangerous devices.

It is hard to imagine an area of study in engineering and/or science for which a basic knowledge and understanding of heat transfer is not an integral part of the discipline .Written at a level that is understandable to both students and practitioners, Heat Transfer Applications for the Practicing Engineer takes a highly pragmatic approach to this important topic. The book's coverage is thorough, its presentation is logical, and it addresses students' needs as well as the needs of the practicing professional.
Although geared towards chemical, mechanical, civil, and environmental engineers working on real-world industrial applications, applied scientists will also find the text a useful reference.
The book is divided into four parts. Part I addresses basic engineering principles. Part II is concerned with heat transfer fundamentals, particularly as they apply to conduction, convection, and radiation. Part III extends the material presented earlier to real-world heat transfer applications. Part IV provides ABET (Accreditation Board for Engineering and Technology) material from a heat transfer perspective. The text features:
-Coverage of topics from the ground up for those readers with little to no background in heat transfer
-Clear, precise explanations on how to carry out calculations associated with heat transfer
-Bridges the gap between heat transfer theory and practice
-Provides specific heat exchange operation, maintenance, and inspection (OH&I) details
-Presents rules of thumb suggestions for heat exchanger design and predictive purposes
-Nearly 300 illustrative examples
-Material that prepares one for the professional engineer's exam
Additional problems on a Wiley website; solutions to these problems plus exams are available for those who adopt the text
Readers will gain a solid working knowledge of heat transfer fundamentals, principles, and applications upon completion of this text, and be better prepared to pass the professional engineer's exam, address more advanced material, and solve more complex problems.
