Book Description
The magneto luminous chemical vapor deposition (MLCVD) method is the perfect example of the "front-end green process." It employs an entirely new process that expends the minimum amount of materials in gas phase, yields virtually no effluent, and therefore requires no environmental remediation. Unlike the "back-end green process," which calls for add-on processes to deal with effluent problems, the newer MLCVD approach is a completely different phenomenon that has never been adequately described, until now. Dispelling previous misconceptions and revealing new areas for investigation, Magneto Luminous Chemical Vapor Deposition describes the key process of dielectric breakdown of gas molecules under the influence of a magnetic field. It emphasizes behavioral distinctions between molecular gasses that cause plasma polymerization (such as methane and trimethylsilane) and mono-atomic gases (e.g., helium and argon) when dealing with the dielectric breakdown of the gas phase under low pressure. The author also reveals his minimum perturbation theory of biocompatibility. This is based on the realization that nanofilms prepared using MLCVD have unique, stable interfacial characteristics necessary to achieve a surface that can be tolerated in various biological environments. The author presents alternating views based on NASA’s recent discovery that a magnetic field burst from the earth triggers the inception of the aurora borealis. Detailing similarities between this phenomenon and the inception of the magneto luminous gas phase described in this book, the author proposes that proof of the one occurrence could shed light on the other. Expanding on the author’s previous works, this book introduces new discoveries, highlights the newfound errors of previous assumptions, and juxtaposes many cutting-edge alternative views and anomalies associated with the field.

Book Description
Medical Coatings and Deposition Technologies is an important new addition to the libraries of medical device designers and manufacturers. Coatings enable the properties of the surface of a device to be controlled independently from the underlying bulk properties; they are often critical to the performance of the device and their use is rapidly growing. This book provides an introduction to many of the most important types of coatings used on modern medical devices as well as descriptions of the techniques by which they are applied and methods for testing their efficacy. Developers of new medical devices and those responsible for producing them will find it an important reference when deciding if a particular functionality can be provided by a coating and what limitations may apply in a given application. Written as a practical guide and containing many specific coating examples and a large number of references for further reading, the book will also be useful to students in materials science & engineering with an interest in medical devices. Chapters on antimicrobial coatings as well as coatings for biocompatibility, drug delivery, radiopacity and hardness are supported by chapters describing key liquid coating processes, plasma-based processes and chemical vapor deposition. Many types of coatings can be applied by more than one technique and the reader will learn the tradeoffs given the relevant design, manufacturing and economic constraints. The chapter on regulatory considerations provides important perspectives regarding the marketing of these coatings and medical devices.

Book Description
Providing in-depth coverage of the technologies and various approaches, Luminous Chemical Vapor Deposition and Interface Engineering showcases the development and utilization of LCVD procedures in industrial scale applications. It offers a wide range of examples, case studies, and recommendations for clear understanding of this innovative science. The book comprises four parts. Part 1 describes the fundamental difference between glow discharge of an inert gas and that of an organic vapor, from which the concepts of Luminous Gas Phase derive. Part 2 explores the various ways of practicing Luminous Vapor Disposition and Treatment depending on the type and nature of substrates. Part 3 covers some very important aspects of surface and interface that could not have been seen clearly without results obtained by application of LCVD. Part 4 offers some examples of interface engineering that show very unique aspects of LCVD interface engineering in composite materials, biomaterial surface and corrosion protection by the environmentally benign process. Timely and up-to-date, the book provides broad coverage of the complex relationships involved in the interface between a gas/solid, liquid/solid, and a solid/solid. The author presents a new perspective on low-pressure plasma and describes key aspects of the surface and interface that could not be shown without the results obtained by LCVD technologies. Features Provides broad coverage of complex relationships involved in interface between a gas/solid, a liquid/solid, and a solid/solid Addresses the importance of the initial step of creating electrical glow discharge Describes the principles of creating chemically reactive species and their growth in the luminous gas phase Focuses on the nature of surface-state of solid and on the creation of imperturbable surface-state by the contacting phase or environment, which is vitally important in creating biocompatible surface, providing super corrosion protection of metals by environmentally benign processes, etc. Offers examples on how to use LCVD in the interface engineering process Presents a new view on low-pressure (low-temperature) plasma and emphasizes the importance of luminous gas phase and chemical reactions that occur in the phase About the author: Dr. Yasuda is one of the pioneers who explored low-pressure plasma for surface modification of materials and deposition of nano films as barrier and perm-selective membranes in the late 1960s. He obtained his PhD in physical and polymer chemistry working on transport properties of gases and vapors in polymers at State University of New York, College of Environmental Science and Forestry at Syracuse, NY. He has over 300 publications in refereed journals and books, and is currently a Professor Emeritus of Chemical Engineering, and Director, Center for Surface Science & Plasma Technology, University of Missouri-Columbia, and is actively engaged in research on the subjects covered by this book.

Book Description
Presents an extensive, comprehensive study of chemical vapor deposition (CVD). Understanding CVD requires knowledge of fluid mechanics, plasma physics, chemical thermodynamics and kinetics, as well as homogenous and heterogeneous chemical reactions. This text presents these aspects of CVD in an integrated fashion, and also reviews films for use in integrated circuit technology.
