Book SynopsisHow Can Polymers Constructed From Living Organisms Help Eliminate the Disposal Issue? A unique category of materials called biodegradable polymers could help remedy a growing environmental concern. Biodegradable Polymeric Nanocomposites: Advances in Biomedical Applications considers the potential of biodegradable polymers for use in biomedical applications that include drug delivery, biosensors, and tissue engineering. Since biomaterials perform on a time-limited function and are designed to disappear from the body after use, the development of biopolymers could greatly reduce and eliminate the need for plastic products, most specifically those used in biomedical applications.Highlights Biomaterials and the Design and Application of BiomaterialsUtilizing expert research contributors from around the world, this book considers the benefits and limitations of a variety of biomaterials, such as biopolTrade Review"Being an outcome of many research efforts precisely combined, this book will appeal to students, academic researchers, biomedical engineers and industrial experts in the field."—Pratheep K.

Book SynopsisCellulose Acetate: Properties, Uses and Preparation presents data on thermodynamic characteristics (heat capacity, enthalpy, entropy, and Gibbs function) from 4 to 580 K cellulose acetates and cellulose nitrates, as well as the major plasticizers for these polymers, the temperatures of their relaxation and phase transitions, the effect of plasticizers on these characteristics of cellulose acetate and cellulose nitrate and the solubility of plasticizers in polymers. Cellulose diacetate has been used in the design of sorption matrices for the fluorescent analysis of polyaromatic and heterocyclic compounds. Thus, the physicochemical properties of cellulose diacetate solutions in a binary acetone-water solvent were analyzed along with the morphological, surface-energy, physicochemical and physicomechanical characteristics of film matrices in comparison with fiber ones. Additionally, the authors examine how the growth of CO2 emissions efforts led to the necessity for green material solutions that fit into a sustainable development policy and low environmental impact. The major barriers to produce cellulose-based products from agricultural residues are the heterogeneity of the raw material, the experimental conditions reproducibility, the heterogeneous phase of the synthesis reaction, the difficulty of purification, the effluent disposal, and the control of the product quality. In the closing study, the authors provide a comprehensive review of electrospun nanofibres from different types of polymers with synthesized montmorillonite clays. Loading activated natural bentonite clay into any type of polymer can improve the adsorption property of electrospun nanofibres, but the bentonite clay must be well dispersed, suspended and loaded to achieve any benefit. This study may pave the way for further use of electrospun nanofibres loaded with clay in a wide variety of environmental and medical applications.

Book SynopsisAn Introduction to Glass Transition opens with a comparison of entropy function of temperature dependence with configurational entropy, which was published by various authors and found almost the same temperature dependence with overlap. From the dependence of the logarithm of configurational entropy vs. the logarithm of temperature, the authors suggest that it is possible to successfully predict the relations between the values of m for different glass formers. Following this, microscopic local dynamics were analyzed by way of atomistic molecular dynamics simulations through the conformational transition behavior across a wide range of temperatures. The glass transition temperature may be predicted through the intersection of separate temperature dependences. Such local dynamics were found to become gradually heterogeneous when the temperature went down close to the glassy state. The closing chapter provides a brief summary of the studies relevant to glass transitions in well-defined lipids systems such as anhydrous and/or water mixed systems. Then, some current problems and future problems are described.Table of ContentsFor more information, please visit our website at:https://novapublishers.com/shop/an-introduction-to-glass-transition/

Book SynopsisThis book focuses on heat-treating by ASM, SME, and AISI standards. The manual has been created for use in student education, as well as to guide professionals who has been heat treating their entire lives. It is written without the typical metallurgical jargon. This book will serve as a training manual from day one in learning how to heat treat a metal, and then also serve as a day to day reference for a lifetime.This manual zeros in on the popular tool steels, alloy steels, heat-treatable stainless steels, case hardening steels, and more. It deals with these metals with up-to-date usage and processing recipes. What is different with this manual from all the others is that it doesn’t just deal with the heat-treatment process, it also covers the continuation of the hardening process with cryogenics. Yes, it is written to help those who may want a thorough understanding of what goes on in the process of heat-treating, and how to do it better. However, it also shows how proper heat and cryogenic processing can save your company money. Making money through longer life tooling, decarb-free and stress relief, all while learning how to create a better, finer grain structure.This manual shows the reader that hardness is only an indication of hardness, and that the real money savings is in the fine grained structure. This manual is written for toolmakers, engineers, heat-treaters, procurement, management personnel, and anyone else who is involved in metals. Metals are affected by the entire thermal scale from 2400°F, down to –320°F. That is the complete range of thermally treated metals and that is what this manual covers.

Book SynopsisThis unified approach to polymer materials science is divided in three major sections: Basic Principles - covering historical background, basic material properties, molecular structure, and thermal properties of polymers. Influence of Processing on Properties - tying processing and design by discussing rheology of polymer melts, mixing and processing, the development of anisotropy, and solidification processes. Engineering Design Properties - covering the different properties that need to be considered when designing a polymer component - from mechanical properties to failure mechanisms, electrical properties, acoustic properties, and permeability of polymers. A new chapter introducing polymers from a historical perspective not only makes the topic less dry, but also sheds light on the role polymers played, for better and worse, in shaping today's industrial world. The first edition was praised for the vast number of graphs and data that can be used as a reference. A new table in the appendix containing material property graphs for several polymers further strengthens this attribute. The most important change made to this edition is the introduction of real-world examples and a variety of problems at the end of each chapter.

Book SynopsisPlastics have a very important role to play in energy-efficient and low-carbon technologies of the present and future, but for them to be classified as sustainable materials, there is a great need for practical and economic recycling methods and infrastructure. This book fills the gap for a modern comprehensive technical guide to recycling of plastics, covering the whole value chain from raw materials to recycled materials.All important recycling technologies (mechanical, chemical/feedstock, dissolution) are discussed and compared to each other and alternative disposal methods such as energy recovery and gasification. Collecting, sorting, and purification methods are also covered, as are economic, legal, and political aspects.A strong emphasis is placed on data comparability, e.g. by standardized methods in measuring data. Although this is a challenge to implement, comparing data across technologies, regions, and stakeholders along the value chain yields important benefits. Key instruments for such a target are lifecycle assessments (LCAs), which are calculated in a standard way across the chapters to "calibrate" the messages among the numerous expert co-authors.Table of Contents 1. Introduction 2. Recycling technologies in overview 3. Value chain (EU, Americas, Asia) 4. Analytics and consumer safety 5. Properties of recycled materials 6. Design for recycling 7.
