Polymer Stress Reactions, Volume 1: Introduction focuses on the interrelationship between polymer mechanochemistry and the stress-induced polymer reactions. This book discusses each nominal polymer state and describes the parameters and variables that are germane to the mechanically induced reactions in that state. The polymer degradation variables that are generally applicable to mechanochemistry, such as temperature and shear intensity, are also considered.
This book consists of five chapters and begins with an overview of mechanochemistry and stress-induced polymer reactions, with particular reference to the distinction between mechanochemical reactions and other modes of reaction. The general regions of viscoelastic behavior for amorphous polymers where mechanochemistry may be conducted are also described. The next chapter explores the mechanisms underlying the modes of reaction in mechanochemistry, focusing on the effects of shear and applied stress as well as how bonds rupture. The discussion then turns to the influence of the principal variables in polymer mechanochemistry; characterization methods for evaluating the fundamentals of mechanochemistry; and methods for the synthesis of block and graft copolymers.
This book is a valuable material for those interested in mechanochemistry in general and in polymer stress reactions in particular.

Polymer–Polymer Miscibility discusses miscibility of polymeric mixtures. This book explains the theoretical and practical aspects of polymer miscibility, which has become a considerable area of research in many academic and industrial laboratories.
Comprised of seven chapters, this book starts with an overview of the physical nature of the variations of the basic polymer structure. This monograph then discusses the two cases of miscible polymer blends, namely, poly(vinyl chloride) (PVC)–butadiene/acrylonitrile copolymer (NBR) and polystyrene–poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) blends. This text explores the useful and unique properties of blends of poly(vinyl chloride) and butadiene/acrylonitrile copolymer rubber. Other chapters discuss the thermodynamic theories for the phase separation of block copolymers. The reader is also introduced to other variations of chemical structure, which can result in the permanent attachment of polymers to each other through block and graft copolymers. This text also explores the feasibility of covalent bonding of polymer components.
This book is intended for chemical engineers and materials scientists.

Polymers and Nanomaterials for Gene Therapy provides the latest information on gene therapy, a topic that has attracted significant attention over the past two decades for the treatment of inherited and acquired genetic diseases. Major research efforts are currently focused on designing suitable carrier vectors that compact and protect oligonucleotides for gene therapy.

The book explores the most recent developments in the field of polymer science and nanotechnology, and how these advancements have helped in the design of advanced materials. Non-viral vector systems, including cationic lipids, polymers, dendrimers, peptides and nanoparticles, are potential routes for compacting DNA for systemic delivery. However, unlike viral analogues that have no difficulty in overcoming cellular barriers and immune defense mechanisms, non-viral gene carriers consistently exhibit significant reduced transfection efficiency due to numerous extra- and intracellular obstacles. Therefore, biocompatibility and potential for large-scale production make these compounds increasingly attractive for gene therapy.

This book contains chapters on the engineering of polymers and nanomaterials for gene therapy, and how they can form complexes with DNA and avoid both in vitro and in vivo barriers. Other chapters describe in vitro, ex vivo, in vivo gene therapy studies, and the current issues affecting non-viral gene therapy.

  • Explores current challenges in the research of genetic diseases
  • Discusses polymers for gene therapy and their function in designing advanced materials
  • Provides examples of organic and inorganic nanomaterials for gene therapy
  • Includes labeling, targeting, and assays
  • Looks at characterization, physico-(bio)chemical properties, and applications

Polyphenols in Human Health and Disease documents antioxidant actions of polyphenols in protection of cells and cell organelles, critical for understanding their health-promoting actions to help the dietary supplement industry. The book begins by describing the fundamentals of absorption, metabolism and bioavailability of polyphenols, as well as the effect of microbes on polyphenol structure and function and toxicity. It then examines the role of polyphenols in the treatment of chronic disease, including vascular and cardiac health, obesity and diabetes therapy, cancer treatment and prevention, and more.

  • Explores neuronal protection by polyphenol metabolites and their application to medical care
  • Defines modulation of enzyme actions to help researchers see and study polyphenols’ mechanisms of action, leading to clinical applications
  • Includes insights on polyphenols in brain and neurological functions to apply them to the wide range of aging diseases

Polyphenols in Plants assists plant scientists and dietary supplement producers in assessing polyphenol content and factors affecting their composition. It also aids in selecting sources and regulating environmental conditions affecting yield for more consistent and function dietary supplements.

Polyphenols play key roles in the growth, regulation and structure of plants and vary widely within different plants. Stress, growth conditions and plant species modify polyphenol structure and content. This book describes techniques to identify, isolate and characterize polyphenols, taking mammalian toxicology into account as well.

  • Defines conditions of growth affecting the polyphenol levels
  • Describes assay and instrumentation techniques critical to identifying and defining polyphenols, critical to researchers and business development
  • Documents how some polyphenols are dangerous to consume, important to dietary supplement industry, government regulators and lay public users

Polysaccharides are the subject of heightened interest today, and this book is a concise and fully up-to-date study of the properties of food polysaccharides, describing their interaction with water, the mass-volume-pressure-relationship, various types of mathematical modeling, and the common phenomenology under different combinations of stimuli. New empirical and theoretical equations, which are not often identified with food technologies, are used to support the findings. Polysaccharide Dispersions: Chemistry and Technology in Food is written in a simple, nontechnical style and should be equally comprehensible to the student, the researcher, the plant manager, and the casual observer with only a modest technical background.

Key Features
* Contains fundamental principles, practical applications, and new discoveries regarding polysaccharides
* Presents material in a simple, easy to understand style
* Focuses exclusively on the food industry

Population and the New Biology contains the papers presented at the 10th annual Symposium of the Eugenics Society and is the third publication in a trilogy on the general theme of "population".
Organized into 13 chapters, separating the papers presented at the symposium, the book begins by discussing the production of living things by relevant methods. It also explains how to identify and care for illness and disability within a span of life, and possibilities for increasing the span, itself. It also talks about the biological nature of, and problems of controlling, common fatal diseases. The future of oral contraceptives, technology for voluntary sterilization, methods of early termination of pregnancy, and the population policies in the developing countries are shown as well. Lastly, the genetic implications, problems, and legal approaches to the “new biology” are given.
This book will fill an important gap in the literature on the implications for population structure and growth of those advances that is known as the "new biology".
