H. J. Hannink and A. J. Hill The ability to measure and manipulate matter at the nanometer level is making possible a new generation of materials with enhanced mechanical, optical, transport and magnetic properties. This important book summarises key developments in nanotechnology and their impact on the processing of metals, polymers, composites and ceramics. After a brief introduction, a number of chapters discuss the practical issues involved in the commercial production and use of nanomaterials. Other chapters review ways of nanoengineering steel, aluminium and titanium alloys. The book discusses the use of nanoengineered metal hydrides to store hydrogen as an energy source, and the development of nanopolymers for batteries and other energy storage devices. It also covers the use of nanotechnology to enhance the mechanical properties of ceramics, the production of synthetic versions of natural materials such as bone, and the development of nanocomposites. Nanostructure control of materials is an ideal introduction to the ways in which nanotechnology is being used to create new materials for industry. It will be welcomed by R&D managers in sectors such as automotive engineering as well as academics working in this exciting area. Dr Richard Hannink is an Honorary Fellow and Dr Anita Hill is a Research Scientist at CSIRO Manufacturing and Infrastructure Technology, Australia.

By using nanolithography, scientists can drive patterning currents through surfaces while building a 3D structure from a series of patterned layers. Electron induced chemical lithography can create ultra-high resolution templates for the site-selective immobilisation of molecules, to form functional, hierarchically organised structures. This new book will concentrate on state-of-the-art nanolithographic methods with a particular emphasis on polymer research. Polymer nanocomposites (ISBN-13: 978-1-85573-969-7; ISBN-10: 1-85573-969-0) This new book concentrates specifically on the four main groups of polymer nanocomposites: layered silicates, nanotube, nanoparticle and block co-polymer systems. There is also a section on inorganic/organic hybrid systems. Each chapter gives comprehensive coverage of the dynamic properties of these materials and the various processing methods used in their production, design, performance and applications. The book is the first to give a comprehensive treatment of the subject. Materials for energy conversion devices (ISBN-13: 978-1-85573-932-1; ISBN-10: 1-85573-932-1) The term electroceramic is used to describe ceramic materials that have been specially formulated with specific electrical, magnetic or optical properties. Electroceramics are of increasing importance in many key technologies including microelectronics, communications and energy conversion. This innovative book is the first comprehensive survey on major new developments in electroceramics for energy conversion devices. It presents current research from leading innovators in the field.
