Looking beyond the traditional applications of polyurethanes (PUR), Polyurethanes as Specialty Chemicals presents a different approach to polyurethane chemistry by examining a range of new products and new research for both environmental and medical applications. This book is also the first in its field to provide useful design tools for product designers to customize the foam surface. The author examines extraction methods and biodegradability of polyurethanes for removing pollutants from air and groundwater and for sanitation/wastewater treatment. Thomson also explores the behavior of polyurethanes in a biological environment, covering a broad spectrum of applications that includes artificial organs, chelating agents for pharmaceuticals, and delivery systems for skin care products and cosmetics. The in-depth treatment of biochemical processes and cellular interaction includes tissue response, cell adhesion, 3D cell scaffolding for cell propagation, the immobilization of enzymes, and the production of proteins. Other topics of interest include agricultural applications and the use of PUR as an analytical/diagnostic system for testing toxicity without the use of animals. Destined to become indispensable in its field, Polyurethanes as Specialty Chemicals explores conventional PUR and its composites - emphasizing formulations, reticulated foams and hydrophilics - as versatile structures that can be used for specific design objectives in environmental and medical applications.

One way of improving performance attributes of building structures is to use a new class of materials—polymer composites. They have unique properties that combine high strength with features of non-metallic materials. Polymer concretes (PC) appear to offer many possibilities for producing new materials with desired physical and mechanical characteristics, such as improved mechanical strength, low permeability, and greater chemical resistance. Advanced Polymer Concretes and Compounds presents the results of theoretical and experimental research on efficient building material composites based on advanced polymer binders. This book examines the composition and properties of two new polymer concretes that have potential to solve various construction issues: rubber concrete based on a polybutadiene binder and silicate polymer concrete with an organo-silicate matrix. It examines the physical, mechanical, and technological properties of these PCs as well as their behavior in harsh environments and durability and reliability issues. The authors describe a new environmentally friendly polymer for monolithic industrial floor coverings and coatings—nonisocyanate polyurethanes. They also discuss advanced crack-resistant coatings based on water dispersion of chlorosulfonated polyethylene, which can be used on concrete, metal, and plastic for various industrial uses such as aircraft, automobiles, paint, and in shipbuilding and civil engineering. The book covers a new type of epoxy composition with nano-heterogenic structure with potential for better mechanical properties and chemical resistance, acid-resistant building materials based on a nanostructured binder, and an advanced environmentally friendly and weather-resistant fire-protective coating for indoor and outdoor application to flammable substrates. With a focus on novel concretes and protective compounds for a variety of environments, this book reflects the newest developments in the rapidly growing field of building materials engineering.

These contribution books collect reviews and original articles from eminent experts working in the interdisciplinary arena of biomaterial development and use. From their direct and recent experience, the readers can achieve a wide vision on the new and ongoing potentialities of different synthetic and engineered biomaterials. Contributions were selected not based on a direct market or clinical interest, but on results coming from a very fundamental studies. This too will allow to gain a more general view of what and how the various biomaterials can do and work for, along with the methodologies necessary to design, develop and characterize them, without the restrictions necessary imposed by industrial or profit concerns. Biomaterial constructs and supramolecular assemblies have been studied, for example, as drug and protein carriers, tissue scaffolds, or to manage the interactions between artificial devices and the body. In this volume of the biomaterial series have been gathered in particular reviews and papers focusing on the application of new and known macromolecular compounds to nanotechnology and nanomedicine, along with their chemical and mechanical engineering aimed to fit specific biomedical purposes.

Control over macromolecular architecture and resulting material properties has been a central goal of polymer chemistry. There has been much interest in developing new synthetic routes to prepare smart materials with novel compositions and topologies for various applications. The considerable progress in the metal mediated macromolecular engineering over the past decade has had a major impact on the development of well-defined macromolecular architectures and the synthesis of smart materials. Particularly, remarkable strong developments have been observed for the synthesis of smart materials via four metal mediated macromolecular engineering techniques; Anionic, ROMP, ATRP and Click Chemistry. These materials have found uses in advanced microelectronics, technical and biomedical applications as well as in chemical sensors applications. This book is comprised of 27 chapters written by leading scientists from NATO and Partner Countries who have greatly contributed in the area of Anionic, ROMP, ATRP and Click Chemistry. It highlights the fundamental aspects and recent developments of these four powerful techniques and evaluate their potential in the syntheses of smart materials from complex structures (grafts, brushes, dendrimers, etc.) to nanostructures (self-assembly, nano-size, etc) for a wide range of applications. The book reports on the synthesis of a wide range of well-defined complex polymeric systems such as thermoresponsive smart polymers, star copolymers, biocompatible polymers, amphipilic smart nano structured, conducting polymers, self assembled polymers, and hyperbranced polymers.

Green nanotechnology has two goals: producing nanomaterials and products without harming the environment or human health, and producing nanoproducts that provide solutions to environmental problems. It uses existing principles of green chemistry and green engineering to make nanomaterials and nanoproducts without toxic ingredients, at low temperatures using less energy and renewable inputs wherever possible, and using lifecycle thinking in all design and engineering stages. The production and process aspects of green nanotechnology involve both making nanomaterials in a more environmentally benign fashion and using nanomaterials to make current chemical processes more environmentally acceptable. This book contains information about advanced nanomaterials that can be produced without harming the environment or human health. This encompasses the production of nanomaterials without environmental toxicity, at room temperature and with the use of renewable energy sources. The book contains the descriptions and results of theoretical and experimental researches in the field of environment friendly nanotechnology carried out over the past decade by the scientific team of company Polymate Ltd.-International Nanotechnology Center (Israel) under leadership of Prof. O. Figovsky. Developments of the Company have been used in industry and agriculture and protected by more than 25 patents of USA, Germany and Russia.
