Book Description
Lignin forms the woody cell walls of plants and the cement material between the plant walls, and after cellulose, it is the second most abundant biopolymer in the world. This book examines the biochemistry of lignin formation, lignin modification and utilization as a polymer, lignin in pulping and bleaching, chemical and physical properties of lignin, and lignin biodegradation.

Book Description
This book addresses the fields of biodegradation, environmental degradation, and photochemical degradation. The purpose of the book is to establish guidelines for terminology, nomenclature, characterization techniques and methodology, mechanisms of degradation, standard reference materials, and issues and needs. This is the first scientific book of this nature based on the findings of the world's leading scientists (academic, industrial, and federal) in this field. Hard data is presented and soft data is identified under issues and needs. New areas covered are such topics as: biodegradation with in vivo applications, environmental degradation, including anaerobic, aerobic, characterization techniques and methodology, photochemical degradation, and secondary issues associated with degradation. This publication contains information vital to environmental scientists and engineers, biomaterials scientists, pharmaceutical technologists, and chemists.

Book Description
Photoinitiating systems for polymerization reactions are largely encountered in a variety of traditional and high-tech sectors, such as radiation curing, (laser) imaging, (micro)electronics, optics, and medicine. This book extensively covers radical and nonradical photoinitiating systems and is divided into four parts: * Basic principles in photopolymerization reactions * Radical photoinitiating systems * Nonradical photoinitiating systems * Reactivity of the photoinitiating system The four parts present the basic concepts of photopolymerization reactions, review all of the available photoinitiating systems and deliver a thorough description of the encountered mechanisms. A large amount of experimental and theoretical data has been collected herein. This book allows the reader to gain a clear understanding by providing a general discussion of the photochemistry and chemistry involved. The most recent and exciting developments, as well as the promising prospects for new applications, are outlined.

Book Description
This timely book presents an unbiased review of biodegradable synthetic polymers and polymers from renewable resources. It examines the state-of-the-art in commodity plastics degradation and disposal, and the greater utilization of agricultural polymers in industrial applications. Biodegradation, photodegradation, and chemical degradation are addressed and various uses for agricultural polymers are explored, including synthesis of rubber from guayule rubber; modification of lignocellulosic fibers to produce high performance composites; modification of cellulose as liquid crystals; and specialty starches for use in the paper industry.

Book Description
The development and use of medical and dental materials are highly interdisciplinary endeavors which require expertise in chemistry, materials science, medicine and/or dentistry, mechanics and design engineering. The Symposium upon which this treatise is based was organized to bring members from these communities together to explore problems of mutual interest. The biomaterials which are used in medical or dental prostheses must not only exhibit structural stability and provide the desired function, but they must also perform over extended periods of time in the environment of the body. The latter is a very stringent requirement. The oral and other physiological environments are designed by nature to break down many organic substances. Also of importance is the requirement that materials used in the prosthesis not have a deleterious effect on body tissues. Most foreign (to the body) substances are somewhat toxic to human tissues; in fact, few factors are more limiting in the medical prosthesis field than the biocompatibility problem. Some of these problems and the attempts to solve them are discussed in this volume.
