Magnetic Bearings for Mechanical Cardiac Assist Devices - Stephen Day - Bog - Momentum Press - Plusbog.dk

This book introduces magnetic bearings--mechatronic devices that produce contact-free electromagnetic force to support a load, such as a moving train or a spinning rotor. Compared to traditional bearings, magnetic bearings offer several advantages: no friction, low heat generation, no required lubrication, quiet operation, and fast and stable rotation. For these reasons, magnetic bearings have been used in rotary ventricular assist devices (VADs) to increase design life, reduce or eliminate material wear and bearing maintenance, as well as to increase biocompatibility by eliminating high fluid stresses and heat generation, both of which are associated with hemolysis, platelet activation and aggregation, and thrombus growth. The book covers the principles of these bearings, how they are used in integrated control and electronics systems, and useful information on several major brands of current assist devices.

Solid State NMR - David C. Apperley - Bog - Momentum Press - Plusbog.dk

Nuclear Magnetic Resonance (NMR) has proved to be a uniquely powerful and versatile tool for analyzing and characterizing chemicals and materials of all kinds. This book focuses on the latest developments and applications for "solid-state" NMR, which has found new uses from archaeology to crystallography to biomaterials and pharmaceutical science research. The book will provide materials engineers, analytical chemists, and physicists, in and out of lab, a survey of the techniques and the essential tools of solid-state NMR, together with a practical guide on applications. In this concise introduction to the growing field of solid-state nuclear magnetic resonance spectroscopy the reader will find: - - Basic NMR concepts for solids, including guidance on the spin-1/2 nuclei concept - - Coverage of the quantum mechanics aspects of solid state NMR and an introduction to the concept of quadrupolar nuclei - - An understanding relaxation, exchange and quantitation in NMR - - An analysis and interpretation of NMR data, with examples from crystallography studies - - Appendices covering spin properties of spin-1/2 nuclides as well as NMR simulation procedures

Characterization of Tribological Materials - William A. Glaeser - Bog - Momentum Press - Plusbog.dk

This revised volume in the MP Characterization series focuses on surface characterization, including roughness, hardness, coating thickness and bond strength. New advancements in characterization methods are also covered for applications in magnetic recording media, rolling contact bearings and other high-tech systems. Tribology, the study of friction, is vital to a wide variety of engineering areas. The ablility to measure and visualize the surface properties that affect friction is vital. This second edition will bring the reader up to date on the latest characterization methods that are particularly useful for studying surface morphology and molecular structure.

The Cell Method - Elena Ferretti - Bog - Momentum Press - Plusbog.dk

Finite Element, Boundary Element, Finite Volume, and Finite Difference Analysis are all commonly used in nearly all engineering disciplines to simplify complex problems of geometry and change. But they all tend to oversimplify. The Cell Method is a more recent computational approach developed initially for problems in solid mechanics and electro-magnetic field analysis. It is a more algebraic approach, and it offers a more accurate representation of geometric and topological features. This will be perhaps the first book-length work in the world that explicates the Cell Method and that shows how useful it can be for practical problem solving, especially in problems in solid mechanics.

Characterization of Composite Materials - Hatsuo Ishida - Bog - Momentum Press - Plusbog.dk

Composite materials make their way into all aspects of modern technological society, but particularly so for applications requiring great strength and light weight such as in the aerospace industry. Because they are hybrid heterogeneous materials, they can be difficult to characterize with any one single methodology. This volume in the Materials Characterization Series will guide engineers and technicians on which methods work best and what to look for when reading results, be they from X-Ray diffraction, or Nuclear Magnetic Imaging. Readers will find: - - Major types of characterization techniques that work best for composite materials, including X-Ray Photoelectron Spectroscopy, Raman Spectroscopy, NMR Imaging and more - - Advanced characterization methods using Scanning Probe Microscopy and Atomic Force Microscopy - - Concise summaries of all major characterization technologies for composite materials

Characterization of Ceramics - Ronald E. Loehman - Bog - Momentum Press - Plusbog.dk

Ceramics are, in a general definition, materials that consist of man-made, inorganic, non-metallic solid material - either existing in a crystalline state or non-crystalline state (i.e., glasses). Materials characterization techniques are used to ensure the structural and surface integrity of ceramics for their use in a wide variety of applications, from thermal resistance to advanced electronic and optical technologies like fiber optics to structural uses. This book presents those techniques along with views on future trends in ceramics processing and advanced characterization technologies particularly appropriate to ceramics materials. Readers will find more on: - - Ceramic Materials preparation routes, including powder preparation by solution techniques and gas-phase techniques - - Formation techniques for ceramic films and coatings, thick films and bulk ceramics - - A review of ceramic microstructure, reactions, phase behavior, mechanical properties and electronic and magnetic ceramics

Carbon: The Next Silicon? - Victor H. Perez Gonzalez - Bog - Momentum Press - Plusbog.dk

Nuclear Magnetic Resonance (NMR) and Electron Spin Resonance (ESR) spectroscopies are well-known characterization techniques that reveal the molecular details of a sample non-invasively. The authors discuss how NMR can provide useful information on the microstructure of carbon and its surface properties and explain how C-MEMS/C-NEMS technology can be explored for building improved NMR microdevices. The authors highlight the manipulation of fluids and particles by dielectrophoresis and the use of carbon electrodes for dielectrophoresis in Lab-on-a-Chip. The use of these electrodes in sample preparation through electrical polarization of a sample for identification, manipulation, and lysis of bioparticles is also discussed and they introduce a new generation of neural prosthetics based on glassy carbon micromachined electrode arrays. The tuning of the electrical, electrochemical and mechanical properties of these patternable electrodes for applications in bio-electrical signal recording and stimulation, and results from in-vivo testing of these glassy carbon microelectrode arrays is reported, demonstrating a quantifiable superior performance compared to metal electrodes.
