Book Description
This book describes a novel strategy to design magnetic paper materials and gain a deeper understanding for the bending behavior of paper-based magnetic actuators upon the application of an external magnetic field. Magnetic paper sheets have been prepared by using different strategies, including the physical entrapment of magnetic beads within surface-attached polymer networks and the covalent attachment of polymer-modified magnetic particles to cellulose fibers. After preparation, the magnetic paper sheets have been characterized with respect to the loading degree, wetting properties, morphology and magnetism by using different methods. Furthermore, paper-based actuators have been fabricated and the bending behavior of such actuators within an external magnetic field has been studied in detail. Thereby, a simple model has been developed to understand the bending behavior of magnetic paper in more depth. In addition, first concepts for the use of magnetic paper sheets in high-tech applications, including magnetic fluid shutters, that allow the fluid transport between adjacent paper sheets, are described.

Book Description
This practical text features computer-aided engineering methods for the design and application of magnetic actuators and sensors, using the latest software tools. John Brauer highlights the use of the electromagnetic finite element software package Maxwell? SV and introduces readers to applications using SPICE, MATLAB?, and Simplorer?. A free download of Maxwell? SV is available at the Ansoft site, and the software files for the examples are available at ftp://ftp.wiley.com/public/sci_tech_med/magnetic_actuators. The text is divided into four parts: * Part One, Magnetics, offers an introduction to magnetic actuators and sensors as well as basic electromagnetics, followed by an examination of the reluctance method, the finite element method, magnetic force, and other magnetic performance parameters * Part Two, Actuators, explores DC actuators, AC actuators, and magnetic actuator transient operation * Part Three, Sensors, details Hall effect and magnetoresistance as they apply to sensing position. Readers are introduced to many other types of magnetic sensors * Part Four, Systems, covers aspects of systems common to both magnetic actuators and sensors, including coil design and temperature calculations, electromagnetic compatibility, electromechanical finite elements, and electromechanical analysis using system models. The final chapter sets forth the advantages of electrohydraulic systems that incorporate magnetic actuators and/or sensors A major thrust of this book is teaching by example. In addition to solved examples provided by the author, problems at the end of each chapter help readers to confirm their understanding of new skills and techniques. References, provided in each chapter, help readers explore particular topics in greater depth. With its emphasis on problem solving and applications, this is an ideal textbook for electrical and mechanical engineers enrolled in upper-level undergraduate and graduate classes in electromechanical engineering.

Book Description
Externally tunable properties allow for new applications of magnetic hybrid materials containing magnetic micro- and nanoparticles in sensors and actuators in technical and medical applications. By means of easy to generate and control magnetic fields, changes of the internal particle arrangements and the macroscopic properties can be achieved. This monograph delivers the latest insights into multi-scale modelling, experimental characterization, manufacturing and application of those magnetic hybrid materials.

Book Description
This most comprehensive and unrivaled compendium in the field provides an up-to-date account of the chemistry of solids, nanoparticles and hybrid materials. Following a valuable introductory chapter reviewing important synthesis techniques, the handbook presents a series of contributions by about 150 international leading experts -- the "Who's Who" of solid state science. Clearly structured, in six volumes it collates the knowledge available on solid state chemistry, starting from the synthesis, and modern methods of structure determination. Understanding and measuring the physical properties of bulk solids and the theoretical basis of modern computational treatments of solids are given ample space, as are such modern trends as nanoparticles, surface properties and heterogeneous catalysis. Emphasis is placed throughout not only on the design and structure of solids but also on practical applications of these novel materials in real chemical situations.
