Bonds Of Wool

The pallium was effective because it was a gift with strings attached. This band of white wool encircling the shoulders had been a papal insigne and liturgical vestment since late antiquity. It grew in prominence when the popes began to bestow it regularly on other bishops as a mark of distinction and a sign of their bond to the Roman church. Bonds of Wool analyzes how, through adroit manipulation, this gift came to function as an instrument of papal influence. It explores an abundant array of evidence from diverse genres - including chronicles and letters, saints' lives and canonical collections, polemical treatises and liturgical commentaries, and hundreds of papal privileges - stretching from the eighth century to the thirteenth and representing nearly every region of Western Europe. These sources reveal that the papal conferral of the pallium was an occasion for intervening in local churches throughout the West and a means of examining, approving, and even disciplining key bishops, who were eventually required to request the pallium from Rome.

The Wool Handbook: Morphology, Structure, Property and Applications explores the fundamental aspects of wool fibers as well as traditional and novel applications of wool in areas including polymer composites and technical textiles. Apart from textiles and garments, wool has long been used for various diversified applications due to its unique material properties. Wool is inherently fire resistant, antimicrobial, flexible and antibacterial, and as a natural material, it can be used to create environmentally sustainable products. This book explains basic and advanced topics related to wool fibers, from shearing to marketing, drawing on academic and industrial research from a range of subjects. Providing statistics, processing methods, and testing and characterization techniques for wool fiber, this book will help readers to use wool fibers to find new applications and solutions. Provides advanced testing methods to explore the material characteristics of wool Includes the latest industrial methods for physical and chemical processing of wool Presents case studies on how wool fibers have been made into successful bio-based composite and textile products

Structure and Properties of High-Performance Fibers explores the relationship between the structure and properties of a wide range of high-performance fibers. Part I covers high-performance inorganic fibers, including glasses and ceramics, plus carbon fibers of various types. In Part II, high-performance synthetic polymer fibers are discussed, while Part III reviews those natural fibers that can be used to create advanced textiles. The high-performance properties of these fibers are related to their chemistry and morphology, as well as the ways in which they are synthesized and spun. High-performance fibers form the basis of textile materials with applications in protection, medicine, and composite reinforcement. Fibers are selected for these technical applications due to their advanced physical, mechanical, and chemical properties. Offers up-to-date coverage of new and advanced materials for the fiber and textile industries Reviews structure-property relationships of high-performance inorganic, carbon, synthetic polymer, and natural fibers Includes contributions from an international team of authors edited by an expert in the field Reviews those natural fibers that can be used to create advanced textiles

“There’s Plenty of Room at the Bottom” ⎯ this was the title of the lecture Prof. Richard Feynman delivered at California Institute of Technology on December 29, 1959 at the American Physical Society meeting. He considered the possibility to manipulate matter on an atomic scale. Indeed, the design and controllable synthesis of nanomaterials have attracted much attention because of their distinctive geometries and novel physical and chemical properties. For the last two decades nano-scaled materials in the form of nanofibers, nanoparticles, nanotubes, nanoclays, nanorods, nanodisks, nanoribbons, nanowhiskers etc. have been investigated with increased interest due to their enormous advantages, such as large surface area and active surface sites. Among all nanostructures, nanofibers have attracted tremendous interest in nanotechnology and biomedical engineering owing to the ease of controllable production processes, low pore size and superior mechanical properties for a range of applications in diverse areas such as catalysis, sensors, medicine, pharmacy, drug delivery, tissue engineering, filtration, textile, adhesive, aerospace, capacitors, transistors, battery separators, energy storage, fuel cells, information technology, photonic structures and flat panel displays, just to mention a few. Nanofibers are continuous filaments of generally less than about 1000 nm diameters. Nanofibers of a variety of cellulose and non-cellulose based materials can be produced by a variety of techniques such as phase separation, self assembly, drawing, melt fibrillation, template synthesis, electro-spinning, and solution spinning. They reduce the handling problems mostly associated with the nanoparticles. Nanoparticles can agglomerate and form clusters, whereas nanofibers form a mesh that stays intact even after regeneration. The present book is a result of contributions of experts from international scientific community working in different areas and types of nanofibers. The book thoroughly covers latest topics on different varieties of nanofibers. It provides an up-to-date insightful coverage to the synthesis, characterization, functional properties and potential device applications of nanofibers in specialized areas. We hope that this book will prove to be timely and thought provoking and will serve as a valuable reference for researchers working in different areas of nanofibers. Special thanks goes to the authors for their valuable contributions.

In this book leading experts within the industry come together to give the first comprehensive treatments of the science and technology of wool to be published in over 20 years. The wool industry has been through a period of substantial change, with a major overhaul of trading methods, exciting innovations in wool-scouring and wool processing methods, and the development of modern technology reflecting a strong emphasis on environmental concerns and energy conservation. Research into wool science has continued to grow, and the technologist now has a better understanding of both the chemical and the physical properties of wool. Modern instruments can determine the structural differences between several types of wool proteins and how they interact, and this knowledge is leading to a deeper understanding of what can be done to create better products and more effective processes. Wool: Science and technology is an essential reference resource for anyone involved in the worldwide wool industry whether as processor, manufacturer, or user for the garment and carpets trades. First new comprehensive treatment of wool for over 20 years Covers all aspects of processing, treatment and manufacture Contributions form distinguished experts worldwide
