Найти книгу: "Chemical Metallurgy"

Chemical metallurgy is a well founded and fascinating branch of the wide field of metallurgy. This book provides detailed information on both the first steps of separation of desirable minerals and the subsequent mineral processing operations. The complex chemical processes of extracting various elements through hydrometallurgical, pyrometallurgical or electrometallurgical operations are explained. In the choice of material for this work, the author made good use of the synergy of scientific principles and industrial practices, offering the much needed and hitherto unavailable combination of detailed treatises on both compiled in one book.

A level 3 Oxford Bookworms Library graded readers. Written for Learners of English by Tim Vicary. The job was too good. There had to be a problem – and there was. John Duncan was an honest man, but he needed money. He had children to look after. He was ready to do anything, and his bosses knew it. They gave him the job because he couldn’t say no; he couldn’t afford to be honest. And the job was like a poison inside him. It changed him and blinded him, so that he couldn’t see the real poison – until it was too late.

Smoking causes and contributes to a large number of human diseases, yet due to the large number of potentially hazardous compounds in cigarette smoke – almost 5,000 chemicals have been identified, establishing the link between smoking and disease has often proved difficult. This unbiased and scientifically accurate overview of current knowledge begins with an overview of the chemical constituents in cigarette smoke, their fate in the human body, and their documented toxic effects on various cells and tissues. Recent results detailing the many ways components of cigarette smoke adversely affect human health are also presented, highlighting the role of smoking in cardiovascular, respiratory, infectious and other diseases. A final chapter discusses current strategies for the treatment and prevention of smoking-induced illness. Despite the obvious importance of the topic, this is the first comprehensive reference on tobacco smoke toxicity, making for essential reading for all toxicologists and healthcare professionals dealing with smoking-related diseases.

This book presents a balance of theoretical considerations and practical problem solving of electrochemical impedance spectroscopy. This book incorporates the results of the last two decades of research on the theories and applications of impedance spectroscopy, including more detailed reviews of the impedance methods applications in industrial colloids, biomedical sensors and devices, and supercapacitive polymeric films. The book covers all of the topics needed to help readers quickly grasp how to apply their knowledge of impedance spectroscopy methods to their own research problems. It also helps the reader identify whether impedance spectroscopy may be an appropriate method for their particular research problem. This includes understanding how to correctly make impedance measurements, interpret the results, compare results with expected previously published results form similar chemical systems, and use correct mathematical formulas to verify the accuracy of the data. Unique features of the book include theoretical considerations for dealing with modeling, equivalent circuits, and equations in the complex domain, review of impedance instrumentation, best measurement methods for particular systems and alerts to potential sources of errors, equations and circuit diagrams for the most widely used impedance models and applications, figures depicting impedance spectra of typical materials and devices, extensive references to the scientific literature for more information on particular topics and current research, and a review of related techniques and impedance spectroscopy modifications.

This book is dedicated to the processes of mineral transformation, recycling and reclamation of metals, for the purpose of turning metals and alloys into a liquid state ready for pouring. Even though «process metallurgy» is one of the oldest technologies implemented by man, technological innovation, with the development of processes that are both focused on product quality and economically and ecologically efficient, continues to be at the heart of these industries. This book explains the physico-chemical bases of transformations, vital to their understanding and control (optimization of operational conditions), and the foundations in terms of «process engineering» (heat and matter assessment, process coupling: chemical reactions and transport phenomena), vital to the optimal execution and analysis of transformation process operations. This book is addressed to students in the field of metallurgy and to engineers facing the problem of metal and alloy development (operation of an industrial unit or development of a new process).
