The Radiation Chemistry of Macromolecules is the first from a two-volume series aiming to contribute to the radiation chemistry in general. The chapters in this volume are divided into two major parts, where the first part deals with the basic processes and theory, while the second part tackles experimental techniques and applications to polyethylene. Part I focuses on the discussion on general principles of radiation effects; fundamental concepts on energy transfer; and the theory of free radicals. The subject of polymers is discussed thoroughly in several chapters including its molecular mobilities and electrical conductivity. Part II presents experimental techniques and a description of the radiation chemistry of a single polymer. This part also includes a discussion on the morphology of polyethylene and free radicals in irradiated polyethylene. This book is an important reference to students and scientists in the field of radiation chemistry of macromolecules.
This monograph—based on the authors course lectures on radiation chemistry of biopolymers—deals with the primary stages of radiation-chemical transformation of main biopolymers. Special attention is given to radiolysis of their aqueous solutions, formation and conversion mechanisms of macroradicals, synthesized in acts of solvent radical interaction with biopolymer molecules and in their natural complexes.
Modern Methods for Theoretical Physical Chemistry of Biopolymers provides an interesting selection of contributions from an international team of researchers in theoretical chemistry. This book is extremely useful for tackling the complicated scientific problems connected with biopolymers' physics and chemistry. The applications of both the classical molecular-mechanical and molecular-dynamical methods and the quantum chemical methods needed for bridging the gap to structural and dynamical properties dependent on electron dynamics are explained. Also included are ways to deal with complex problems when all three approaches need to be considered at the same time. The book gives a rich spectrum of applications: from theoretical considerations of how ATP is produced and used as 'energy currency' in the living cell, to the effects of subtle solvent influence on properties of biopolymers and how structural changes in DNA during single-molecule manipulation may be interpreted.· Presents modern successes and trends in theoretical physical chemistry/chemical physics of biopolymers· Topics covered are of relevant importance to rapidly developing areas in science such as nanotechnology and molecular medicine· Quality selection of contributions from renowned scientists in the field
The book is concerned with the application of physical techniques to the study of the structure and interactions of biopolymers. The treatment is confined to those procedures applicable to solutions. The material has been tested on students in actual classes, thereby permitting the elimination of ambiguities and potential points of difficulty. Stress has been placed upon lucidity of treatment, and difficult steps in derivations have been explained. The mathematical exposition has been made as clear and simple as feasible. Examples of actual data are given.
Biopolymers and biodegradable plastics are finding new applications in various sectors, from packaging, to medical, automotive and many more. As synthetic plastics are increasingly replaced by their bioplastic equivalents, engineers are facing new challenges including processing, costs, environmental sustainability and – ultimately – developing successful products. Biopolymers: Processing and Products, the second book of a trilogy dedicated to biopolymers, gives a detailed insight into all aspects of processing, seamlessly linking the science of biopolymers to the latest trends in the development of new products. Processes covered in the book include blending, compounding, treatment, and shaping, as well as the formation of biocomposites. Biopolymer coatings and adhesives are also investigated. This book unique in its coverage contains information retrieved mainly from patents, which form the bulk of the book. The coverage of processing will help engineers and designers to improve output and efficiency of every stage of the product development process, and will form an indispensable tool in selecting the right biopolymer and processing technique for any given application, covering medical, automotive, food packaging and more. It will assist also engineers, material scientists and researchers to improve existing biopolymer processes and deliver better products at lower cost. - Multi-disciplinary approach and critical presentation of all available processing techniques and new products of biopolymers - Contains information not to be found in any other book - Self-contained chapters
The Radiation Chemistry of Macromolecules, Volume II is a collection of papers that discusses radiation chemistry of specific systems. Part 1 deals with radiation chemistry of substituted vinyl polymers, particularly polypropylene (PP) as its structure is intermediate between polyethylene and polyisobutylene. This part also discusses polypropylene oxide (PPOx) for it can be prepared in the atactic, isotactic, and optically active forms. One paper focuses on the fundamental chemical processes and the changes in physical properties that give rise to many different applications of polystyrene. Another paper analyzes poly(methyl methacrylate) and poly(isobutylene)—two important polymers of nongelling substances subject to radiation. Part 2 describes the radiation chemistry of some miscellaneous polymers including the formation of free radicals and their termination. One paper also considers the radiation chemistry of polytetrafluoroethyle (PTFE), which is widely used in industry. Part 3 discusses the effect of radiation on oxidation, mechanical properties, and physical state of polymers. Part 4 addresses macromolecules, particularly the radiation chemistry of biopolymers because of their role in radiation chemistry. The damage done to biopolymers through radiation can affect the responses of living organisms to ionizing radiation. This book can prove valuable to scientists and researchers in the fields of nuclear biology, nuclear science, microchemistry, and cellular biology.
Radiation-Processed Polysaccharides: Emerging Roles in Agriculture is the first book to focus exclusively on this emerging and important option for reducing the overuse and negative impact of agrochemicals in agriculture. Among practices being developed for effective and eco-friendly plant growth regulators in crop production, using radiation-processed polysaccharides (RPPs) is a promising technique. Comprised of chapters from diverse areas of plant science, including agriculture, agronomy, biotechnology, nanotechnology, molecular biology, and radiation agriculture, this book provides insights into the practical application of RPPs and inspires further research toward sustainable and efficient agricultural production. Polysaccharides (sodium alginate, carrageenan, chitosan and others) in their depolymerized state are increasingly important to agriculture based on their unique biological properties, biocompatibility, biodegradability and non-toxicity. Understanding the impact of RPPs on the plant phenotype, translocation of nutrients from source to sink, signal processing, and crosstalk helps improve the applicability of RPPs and sustainable agricultural yield. Presents the latest application of RPPs for improved plant production Includes insights for abiotic stress, biotechnology, nanotechnology and molecular application Explores the efficiency of natural polysaccharides as plant growth promoters
This volume is a review of the trends in the field of radiation chemistry research. It covers a broad spectrum of topics, ranging from the historical perspective, instrumentation of accelerators in the nanosecond to femtosecond region, through the use of radiation chemical methods in the study of antioxidants and nanomaterials, radiation-induced DNA damage by ionizing radiation involving both direct and indirect effects, to ultrafast events in free electron transfer, radiation-induced processes at solid-liquid interfaces and the recent work on infrared spectroscopy and radiation chemistry. The book is unique in that it covers a wide spectrum of topics that will be of great interest to beginners as well as experts. Recent data on ultrafast phenomena from the recently established world-class laser-driven accelerators facilities in the US, France and Japan are reviewed.
