Available in PDF, EPUB and Kindle. Book excerpt: Accelerated Aging: Photochemical and Thermal Aspects represents the culmination of more than 40 years of research by noted scientist Robert L. Feller. The book focuses on the long-term performance of materials such as wool, dyes, and organic compounds; their resistance to change when exposed to environmental factors such as oxygen, ozone, moisture, heat, and light; and their physical durability with handling and use over time. Processes of deterioration are discussed based on speeded-up laboratory studies designed to clarify the chemical reactions involved and their physical consequences.

Book excerpt: Cellulose is the most widely spread organic polymer found in nature, since it constitutes the main component of the membrane of plant cell. It is well-known that cellulose is a very important and fascinating biopolymer and an almost inexhaustible and renewable raw material. This book provides a synthesis of the old knowledge and the development of different studies which contribute to the understanding of the structure of cellulose allomorphs. In addition, cellulosic ethanol has been taken as a promising alternative energy source for the non-renewable fossil fuel. This book reviews the development of biochemical conversion of biomass materials into cellulosic ethanol, including previous achievements, current status, and future work. The various aspects of natural and accelerated ageing of cellulose are also presented and discussed. Other chapters in this book explore the basic principles of cellulose oxidation chemistry with a focus on different products of the reactions. The main part of the chapter focuses on both known and newly proposed applications of oxidised celluloses in medical, cosmetic, hygiene and food industry. A critical analysis is also made of the literature concerned with the kinetics of cellulose degradation. Furthermore, this book reviews bacterial cellulose (BC), an outstanding biomaterial with unique properties, including high water holding capacity, high crystallinity and ultrafine fibre network. These properties support a wide range of applications, in human and veterinary medicine, odonthology, pharmaceutical industry, acoustic and filter membranes, biotechnological devices and in the food and paper industry.

Book excerpt: Beginning with a general overview of nanocomposites, Bionanocomposites: Integrating Biological Processes for Bio-inspired Nanotechnologies details the systems available in nature (nucleic acids, proteins, carbohydrates, lipids) that can be integrated within suitable inorganic matrices for specific applications. Describing the relationship between architecture, hierarchy and function, this book aims at pointing out how bio-systems can be key components of nanocomposites. The text then reviews the design principles, structures, functions and applications of bionanocomposites. It also includes a section presenting related technical methods to help readers identify and understand the most widely used analytical tools such as mass spectrometry, calorimetry, and impedance spectroscopy, among others.
Book Synopsis Evaluation of Cellulose Ethers for Conservation by : Robert L. Feller
Download or read book Evaluation of Cellulose Ethers for Conservation written by Robert L. Feller and published by Getty Publications. This book was released on 1991-03-21 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is the result of a three-year research program. It describes the chemical character of cellulose ethers as a general class of polymers and establishes an approximate ranking of the relative stability of each generic chemical subclass. Ranking the thermal stability of the polymers with respect to color change and loss in degree of polymerization led to the conclusion that as generic chemical classes, methylcellulose and carboxymethylcellulose appear to be the most stable of the cellulose ethers. Water-soluble ethylhydroxyethylcellulose apparently also possesses good stability. Of questionable long-term stability are hydroxyethylcellulose and hydroxy- propylcellulose. Ethylcellulose and organic-soluble ethylhydroxyethylcellulose proved to be of poor stability, potentially undergoing marked changes in twenty years or less under normal museum conditions. An important additional conclusion reached here, as well as in an earlier investigation, is that considerable variations in stability can occur within a generic chemical class from differences in the basic raw material, a natural product from plants, which is not a uniform, manufactured, chemical substance. Further variations can exist due to different manufacturing processes or commercial sources. Hence, commercial products must be evaluated individually to determine the most stable of a given generic type. Nonetheless, the authors believe the conclusions expressed here to be valid with regard to the relative stability of the generic chemical classes of cellulose ethers.

This book was released on 2017-10-13 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Service Life Prediction of Polymers and Plastics Exposed to Outdoor Weathering discusses plastics and polymers and their unique applications, from sealants used in construction, to polymer composites used in planes. While these materials are important enablers for advanced technologies, exposure to weather changes the very properties of plastics that make them so useful. This book reviews current research needs and provides a consensus roadmap of the scientific barriers to validated predictive models for the response of polymers and plastics to outdoor exposure. Despite extensive efforts over the past 20-30 years, testing of polymeric materials in accelerated or natural weathering conditions and the interpretation of the weathering results still require substantial improvements. This book represents the state-of-the-art in the prediction techniques available and in development. Engineers and materials scientists working in this field will be able to use the content of this book to assess the strengths and challenges of a range of different methods and approaches. - Enables engineers and scientists in a range of industries to more successfully predict the durability of polymers, paints and coatings when exposed to weather - Provides the latest information to help determine the sustainability of polymeric materials - Reviews the current state-of-the-art in this area and identifies research needs that are followed by more detailed discussions of specific polymers and applications
