This book provides a solid overview of the important metallurgical concepts related to the microstructures of irons and steels, and it provides detailed guidelines for the proper metallographic techniques used to reveal, capture, and understand microstructures. This book provides clearly written explanations of important concepts, and step-by-step instructions for equipment selection and use, microscopy techniques, specimen preparation, and etching. Dozens of concise and helpful 'metallographic tips' are included in the chapters on laboratory practices and specimen preparation. The book features over 500 representative microstructures, with discussions of how the structures can be altered by heat treatment and other means. A handy index to these images is provided, so the book can also be used as an atlas of iron and steel microstructures. Contents include: Introduction to steels and cast irons; Origin of microstructure; Alteration of microstructure; The metallographer and the metallographic laboratory; The metallurgical microscope; The expanded metallographic laboratory; Metallographic specimen preparation; The art of revealing microstructure; Appendices; Index.
From the Columbian Exchange beginning in 1492, the development of slavery as a Southern institution, and the westward movement to the dust bowl, the Endangered Species Act, and the destruction caused by the BP oil spill in the Gulf of Mexico, human interaction with the environment in America has been continuous, open-ended, and dynamic.
What happens to a chemical once it enters the natural environment? How do its physical and chemical properties influence its transport, persistence, and partitioning in the biosphere? How do natural forces influence its distribution? How are the answers to these questions useful in making toxicological and epidemiological forecasts?<br> <br> Environmental Chemodynamics, Second Edition introduces readers to the concepts, tools, and techniques currently used to answer these and other critical questions about the fate and transport of chemicals in the natural environment. Like its critically acclaimed predecessor, its main focus is on the mechanisms and rates of movement of chemicals across the air/soil, soil/water, and water/air interfaces, and on how natural processes work to mobilize chemicals near and across interfaces--information vital to performing human and ecological risk assessments.<br> <br> Also consistent with the first edition, Environmental Chemodynamics, Second Edition is organized to accommodate readers of every level of experience. The first section is devoted to theoretical underpinnings and includes discussions of mass balance, thermodynamics, transport science concepts, and more. The second section concentrates on practical aspects, including the movement between bed-sediment and water, movement between soil and air, and intraphase chemical behavior.<br> <br> This revised and updated edition of Louis J. Thibodeaux's 1979 classic features new or expanded coverage of: <br> * Equilibrium models for environmental compartments <br> * Dry deposition of particles and vapors onto water and soil surfaces <br> * Chemical profiles in rivers and estuaries, particles and porous media <br> * Fate and transport in the atmospheric boundary layer and within subterranean media <br> * Chemical exchange between water column and bed-sediment <br> * Intraphase chemical transport and fate<br> <br> <br> This Second Edition of Environmental Chemodynamics also includes twice as many references and 50% more exercises and practice problems.
Lovinia lives in a high-rise luxury apartment far from the Maroko shantytown of her origins, but she wakes up one morning to discover she is in chains. She must escape her chains or be doomed to the fate of her father who was ruined by the shackles of destructive cultural beliefs...
Describing novel methods and catalytic strategies to conserve and maintain air, water, and soil quality, researchers from a range of disciplines discuss the role of interface science in environmental remediation. They detail approaches to separate, reuse, recover, and treat potentially valuable materials using techniques in ion exchange and adsorption; develop and design new catalysts to enhance production, energy, and cost efficiency; and evaluate and improve existing treatment strategies for recycling of plastics and wastes. The 17 studies were developed from presentations at the symposium Application of Interface Science to Environmental Pollution Control (Chicago, August 2001).
