Chain Mobility and Progress in Medicine, Pharmaceuticals, and Polymer Science and Technology covers the core fundamentals and applications of chain movement, chain mobility, segmental mobility, segmental dynamics, and chain orientation in polymer science, medicine, pharmaceuticals, and other disciplines. The book starts by defining principal terms, then looks at the work of Pierre-Gilles de Gennes and his 1991 Nobel Prize in Physics for his work on polymer-chain motion. From there the book discusses the different mechanisms of chain motion of macromolecular substances, the conditions under which chains move, and the effects of these movements on properties of materials, such as chain alignment, chain orientation, creation of free volume, dimensional stability, and more. The final chapters provide insight on analytical methods of chain movement, chain movement phenomena in different polymers, and various fields of application. All concepts, findings, and applications are discussed in easy-to-understand language stripped of disciplinary slang, making the book accessible to researchers and practitioners across a variety of scientific fields.

Functional Fillers: Chemical Composition, Morphology, Performance, Applications demonstrates the applications of fillers, their chemical composition or modification, and morphological features. The book includes two sections, with the first part covering classic fillers, analyzing the current modifications in relation to composition and morphology, and enabling enhancements in properties and applications. The second part presents the new generation of fillers, which are providing designers with exceptional properties not previously available with classic fillers used in industry. This book supports engineers, researchers and technicians working with fillers, and will be of great interest to professionals working across the chemical, pharmaceutical, medicinal and electronics industries.

This book describes high frequency power MOSFET gate driver technologies, including gate drivers for GaN HEMTs, which have great potential in the next generation of switching power converters. Gate drivers serve as a critical role between control and power devices.

Self-Healing Materials: Principles and Technology is a practical book aimed at giving engineers and researchers in both industry and academia the information they need to deploy self-healing technology in a wide range of potential applications¿from adhesives to the automotive industry, and from electronics to biomedical implants. Developments are increasingly seeing real-world application, and this book enables practitioners to use this technology in their own work. The book first discusses the principal mechanisms of self-healing and how these are applied to the development of materials which have the ability to repair themselves¿either with minimal human intervention or without human intervention at all. The book provides a theoretical background and a review of the major research undertaken to date, to give a thorough grounding in this concept and related technology. The book specifically covers fault detection mechanisms in materials, and experimental methods to enable engineers to assess the efficiency of the self-healing process. It then discusses typical aids and additives in self-healing materials, including plasticizers, catalysts, shape-memory components, and more. Finally, the book contains real world examples of self-healing materials and how these have been applied to around 40 groups of products and industries, including materials used in the automotive industry, construction, composite materials for aerospace, biomaterials and materials used in medical devices, and adhesives and sealants.
