Environmental remediation technologies to control or prevent pollution from hazardous waste material is a growing research area in academia and industry, and is a matter of utmost concern to public health, to improve ecology and to facilitate the redevelopment of a contaminated site. Recently, in situ and ex situ remediation technologies have been developed to rectify the contaminated sites, utilizing various tools and devices through physical, chemical, biological, electrical, and thermal processes to restrain, remove, extract, and immobilize mechanisms to minimize the contamination effects. This handbook brings altogether classical and emerging techniques for hazardous wastes, municipal solid wastes and contaminated water sites, combining chemical, biological and engineering control methods to provide a one-stop reference. This handbook presents a comprehensive and thorough description of several remediation techniques for contaminated sites resulting from both natural processes and anthropogenic activities. Providing critical insights into a range of treatments from chemical oxidation, thermal treatment, air sparging, electrokinetic remediation, stabilization/solidification, permeable reactive barriers, thermal desorption and incineration, phytoremediation, biostimulation and bioaugmentation, bioventing and biosparging through ultrasound-assisted remediation methods, electrochemical remediation methods, and nanoremediation, this handbook provides the reader an inclusive and detailed overview and then discusses future research directions. Closing chapters on green sustainable remediation, economics, health and safety issues, and environmental regulations around site remediation will make this a must-have handbook for those working in the field.

The current chemical engineering curriculum concentrates on process: the efficient manufacturing in quantity of traditional chemical products such as ammonia and benzene. However, many chemical companies now invent and manufacture specialty products with particular properties such as pharmaceuticals, cosmetics, and electronic coatings, and their employees need to know how to design the products as well as manufacture them. James Wei, a famous chemical engineer, is writing this book to provide theories and case studies in product engineering the design of new, useful products with desired properties. The first section relates historical case studies of successful product invention and development by individuals and companies. The second part of the book describes the toolbox of molecular structure-property relations. A desired product needs to have certain properties (for example, phase transition or thermal properties) and the chemist must find or design a molecular structure with the required properties This section will instruct chemists in the analysis of structure and property information. The third section is concerned with the next stage: product research and design. It will discuss improving the desired product by additives and blending, among other strategies. It will also cover future challenges in product engineering.

Since the first edition published more than 100 years ago, Machinery's Handbook has been acknowledged as an exceptionally authoritative and comprehensive, yet highly practical, and easy-to-use tool, and the new 31st edition has grown to nearly 3,000 pages. The Guide to the Use of Tables and Formulas in the Machinery's Handbook, 31st Edition, is designed to maximize the enormous practical value of the latest, greatest edition of this invaluable engineering resource, offering useful information on how to make full use of the Machinery's Handbook in solving problems on the job. Features Revised to reflect numerous changes made in the new 31st edition, with specific cross references to quickly locate information in the far larger book, the Guide enables users to become familiar with the Handbook's vast range of vital content. Offering more than 150 worked-out examples and nearly 500 review questions (with answers) specially selected for engineers, apprentices, and students, the Guide addresses problems commonly encountered in manufacturing and metalworking. By following practical techniques explained in the Guide and cross-referenced to the Handbook, readers will enhance their ability to reach specific information and solutions more quickly and easily. The Guide also is sold as a standalone eBook and is part of the Machinery's Handbook 31 Digital Edition, which includes the complete contents of the 31st edition, and more.
