Book Description
The third method invented is called the Rolling-assisted-biaxially-textured-substrates (RABiTS). The book is divided into four sections. The first section discusses the three methods to fabricate biaxially textured substrates, upon which, epitaxial YBCO or other HTS materials can be deposited to realize a single-crystal-like HTS wire. The second section includes chapters on various methods of HTS deposition such as pulsed laser ablation (PLD), thermal co-evaporation, sputtering, pulsed electron beam deposition, ex-situ BaF2 by co-evaporation flowed by annealing, chemical solution based ex-situ processes, jet vapor deposition, metal organic chemical vapor deposition (MOCVD), and liquid phase epitaxy (LPE). The third section includes detailed chapters on other HTS materials such as the various Tl-based and Hg-based conductors. These Second-Generation HTS conductors, also referred to as "Coated conductors" represent one of the most exciting developments in HTS technology.

Book Description
High temperature superconductors (HTS) offer many advantages through their application in electrical systems, including high efficiency performance and high throughput with low-electrical losses. While cryogenic cooling and precision materials manufacture is required to achieve this goal, cost reductions without significant performance loss are being achieved through the advanced design and development of HTS wires, cables and magnets, along with improvements in manufacturing methods. This book explores the fundamental principles, design and development of HTS materials and their practical applications in energy systems.Part one describes the fundamental science, engineering and development of particular HTS components such as wires and tapes, cables, coils and magnets and discusses the cryogenics and electromagnetic modelling of HTS systems and materials. Part two reviews the types of energy applications that HTS materials are used in, including fault current limiters, power cables and energy storage, as well as their application in rotating machinery for improved electrical efficiencies, and in fusion technologies and accelerator systems where HTS magnets are becoming essential enabling technologies.With its distinguished editor and international team of expert contributors, High temperature superconductors (HTS) for energy applications is an invaluable reference tool for anyone involved or interested in HTS materials and their application in energy systems, including materials scientists and electrical engineers, energy consultants, HTS materials manufacturers and designers, and researchers and academics in this field. - Discusses fundamental issues and developments of particular HTS components - Comprehensively reviews the design and development of HTS materials and then applications in energy systems - Reviews the use of HTS materials and cabling transmissions, fault alignment limiters, energy storage, generators and motors, fusion and accelerator

Book Description
The objective of the program is to develop a fundamental understanding of YBCO film deposition by Metal Organic Chemical Vapor Deposition (MOCVD) on biaxially-textured metal substrates. In comparison to other vapor deposition techniques, MOCVD offers the advantages of rapid deposition rates, film uniformity over large areas, and is not limited to line-of-sight deposition. The program includes a study of the a) influence of MOCVD processing conditions such as the flow rate of precursor vapors, precursor vaporization temperatures, oxygen partial pressure, reactor pressure, and the deposition temperature on the film features such as superconducting phase formation, composition, texture, deposition rates, uniformity in thickness, porosity and the presence of secondary phases, b) relationship between film microstructure and the critical current density (Jc), and c) influence of metal substrate and buffer layers on the growth and performance of YBCO.

Book Description
The impending energy crisis brought on by the running out of finite and non-homogenously distributed fossil fuel reserves and the worldwide increase in energy demand has prompted vast research in the development of sustainable energy technologies in the last few decades. However, the efficiency of most of these new technologies is relatively small and therefore it needs to be increased to eventually replace conventional technologies based on fossil fuels. The required efficiency increase primarily relies on the ability to improve the performance of the functional materials which are at the heart of these technologies. The purpose of this book is to give a unified and comprehensive presentation of the fundamentals and the use and design of novel materials for efficient sustainable energy applications, such as conversion, storage, transmission, and consumption. The book presents general coverage of the use and design of advanced materials for sustainable energy applications. Thus, the book addresses all the relevant aspects, such as materials for energy conversion, storage, transmission, and consumption.

Book Description
This is the first of three volumes of the extensively revised and updated second edition of the Handbook of Superconductivity. The past twenty years have seen rapid progress in superconducting materials, which exhibit one of the most remarkable physical states of matter ever to be discovered. Superconductivity brings quantum mechanics to the scale of the everyday world where a single, coherent quantum state may extend over a distance of metres, or even kilometres, depending on the size of a coil or length of superconducting wire. Viable applications of superconductors rely fundamentally on an understanding of this intriguing phenomena and the availability of a range of materials with bespoke properties to meet practical needs. This first volume covers the fundamentals of superconductivity and the various classes of superconducting materials, which sets the context and background for Volumes 2 and 3. Key Features: Covers the depth and breadth of the field Includes contributions from leading academics and industry professionals across the world Provides hands-on guidance to the manufacturing and processing technologies A comprehensive reference, this handbook is suitable for both graduate students and practitioners in experimental physics, materials science and multiple engineering disciplines, including electronic and electrical, chemical, mechanical, metallurgy and others.

Book Description
YBa2Cu3O2 (YBCO) films have been deposited on buffered metal substrates by Metal Organic Chemical Vapor Deposition (MOCVD). Cube-textured nickel substrates were fabricated by a thermomechanical process. Epitaxial CeO2films were deposited on these substrates by thermal evaporation. Nickel alloy substrates with biaxially-textured Yttria-Stabilized Zirconia (YSZ) buffer layers deposited by Ion Beam Assisted Deposition were also prepared. Highly biaxially-textured YBCO films were deposited by MOCVD on both types of metal substrates. A critical current density greater than 105 A/cm2 at 77 K has been achieved in YBCO films on metal substrates.
