The area of tribology deals with the design, friction, wear and lubrication of interacting surfaces in relative motion. Polymer nanocomposite materials are increasingly common and offer remarkable improvements in the friction and wear properties of both bulk materials and coatings. This book gives a comprehensive description of polymeric nanocomposites, both as bulk materials and as thin surface coatings, and their behavior and potential use in tribological applications. It provides the preparation techniques, friction and wear mechanisms, properties of polymeric nanocomposites, characterization, evaluation and selection methodology. It also provides various examples of application of polymeric nanocomposites. * Provides a complete reference from the preparation to the selection of polymeric nanocomposites * Explains the theory through examples of real-world applications * More than 20 international tribology experts contribute to their area of expertise

Many geologists have an equivocal attitude to fluid movements within the crust and the associated changes in the chemical and physical properties of crustal rocks. The controversies earlier this centuary between the "soaks" and the "pontiffs" memorably summarised by H. H. Read (1957) in The Granite Controversy have largely been resolved. Few would now advocate the formation of large granitic bodies by in situ transformation of pre-existing crust as the result of the passage of ichors without the formation of a granitic melt. To many geochemists fluid transport and metasomatism have become slightly suspect processes which at the most locally disturb the primary geochemical and isotopic signatures. While there is common agreement that there are marked differences in the composition of the lower and upper crust, the role of fluid movement as one of the controls of this differentiation is often neglected in favour of suggested primary differences in the composition of igneous rocks emplaced at different depths. Selective fluid transport however provides many geologists with their livelyhood. Without the secondary concentration of commercially important elements by fluids within the crust the mining industry, geological science and human activities based on their products would be very different.

This handbook helps engineers in industry with the operation and maintenance of machinery. It provides the information that these engineers need in a form that is instantly accessible and easy to read. The manufacturers of machinery give guidelines on the operation, lubrication and maintenance required for their particular equipment. There are however many different machines in an industrial plant or service organisation, often supplied by many different manufacturers, and there is a need to select as many similar lubricants as possible and to use related machine techniques. This book bridges the gap which exists between the available data on the various machines by providing overall guidance on how to co-ordinate the recommendations of the various equipment makers. The book is structured in a number of sections that will make it easier to use, and to bring together related topics so that when a reader is focusing on a particular problem they can also refer to related material that is also likely to be of interest. THE handbook for an industrial audience consisting of plant engineers and maintenance managers. It describes the essential theory and practice relating to matters of lubrication and reliability. Unique layout and presentation of information makes this one of the best practical reference books available.

Graphite, Graphene, and Their Polymer Nanocomposites presents a compilation of emerging research trends in graphene-based polymer nanocomposites (GPNC). International researchers from several disciplines share their expertise about graphene, its properties, and the behavior of graphene-based composites. Possibly the first published monograph of its kind, this book provides a comprehensive snapshot of graphite, graphene, and their PNCs, including the underlying physics and chemistry, and associated applications. Beginning with an introduction to natural and synthetic graphite, the precursors to graphene, the text describes their properties, characterization techniques, and prominent commercial applications. The focus then moves to graphene and its unique features, and techniques for its characterization. The chapters cover advances in electrochemical exfoliation of graphite, as well as exfoliation routes to produce graphene and graphite nanoplatelets for polymer composites. They also explore commercial use of graphene-based materials, such as emerging clean energy and pulse laser applications, and use as nanofillers in epoxy-based composites. The authors provide an overview of nanofillers and address two methods for GPNC preparation as well as specialized properties of GPNC. With its multidisciplinary approach, this book provides a broader scientific and engineering perspective necessary for meaningful advancements to take place.
