This book presents the "helical wormlike chain" model - a general model for both flexible and semiflexible polymer chains. It explains how statistical-mechanical, hydrodynamic, and dynamic theories of their solution properties can be developed on the basis of this model. This new second edition has been carefully updated and thoroughly revised. It includes a new chapter covering "Simulation and More on Excluded-Volume Effects", as well as the discussion of new experimental data and the application of the theory to ring polymers. The authors provide analysis of important recent experimental data by the use of their theories for flexible polymers over a wide range of molecular weights, including the oligomer region, and for semiflexible polymers, including biological macromolecules such as DNA. This is all clearly illustrated using a reasonable number of theoretical equations, tables, figures, and computer-aided forms, which support the understanding of the basic theory and help to facilitate its application to experimental data for the polymer molecular characterization.
The topic of this thesis is catalytic conversion of non-food, abundant, and renewable biomass such as cellulose and chitin to chemicals. In biorefinery, chemical transformation of polymers to valuable compounds has attracted worldwide interest for building sustainable societies. First, the current situation of this hot research area has been summarized well in the general introduction of the thesis, which helps readers to become familiar with this topic. Next, the author explains high-yielding production of glucose from cellulose by using an alkali-activated carbon as a catalyst, resulting in a yield of glucose as high as 88%, which is one of the highest yields ever reported. The characterization of carbon materials has indicated that weak acid sites on the catalyst promote the reaction, which is markedly different from reported catalytic systems that require strong acids. In addition, the first catalytic transformation of chitin with retention of N-acetyl groups has been developed. The combination of mechanocatalytic hydrolysis and thermal solvolysis enables the production of N-acetylated monomers in good yields of up to 70%. The catalytic systems demonstrated in this thesis are unique in the fields of both chemistry and chemical engineering, and their high efficiencies can contribute to green and sustainable chemistry in the future. Meanwhile, mechanistic studies based on characterization, thermodynamics, kinetics, and model reactions have also been performed to reveal the roles of catalysts during the reactions. The results will be helpful for readers to design and develop new catalysts and reaction systems.

This book describes industrial applications of polyolefins from the researchers' perspective. Polyolefins constitute today arguably the most important class of polymers and polymeric materials for widespread industrial applications. This book summarizes the present state of the art. Starting from fundamental aspects, such as the polymerization techniques to synthesize polyolefins, the book introduces the topic. Basic knowledge about polyolefin composites and blends is explained, before applications aspects in different industry sectors are discussed. The spectrum comprises a wide range of applications and industry sectors, such as the packaging and food industry, the textile industry, automotive and buildings, and even biomedical applications. Topics, which are addressed in the various chapters, comprise synthesis and processing of the materials; their classification; mechanical, physical and technical requirements and properties; their characterization; and many more. In the end of the book, even the disposal, degradation and recycling of polyolefins are addressed, and light is shed on their commercial significance and economic value. In this way, the book follows the entire 'lifetime' of polyolefin compounds and materials: from their synthesis and processing, over applications, to the recycling and reuse of disposed or degraded polyolefin substrates.

A membrane is considered the heart of every separation process because it is developed as a nanostructured/nanofunctionalized thin barrier that controls the exchange between two phases, not only by external forces and under the effect of fluid properties, but also through the intrinsic characteristics of the membrane material itself. This book compiles cutting-edge research in membrane science, nanomaterials, and nanotechnologies, mainly from interdisciplinary research groups at the Institute on Membrane Technology, National Research Council (ITM-CNR), Italy, working on membrane design, membrane process engineering, and selected materials and practices for enhanced transport mass, charge, and energy. It covers topics on the design of new nanostructured membranes with improved properties, together with the identification of efficient transport-property relationships. It shares and strengthens the knowledge of making membrane technology a much more powerful and eco-friendly route, enabling one to provide prospective solutions and benefits for numerous fields of applications where traditional separation technologies suffer from many deficiencies. It is a great reference for researchers and investigators; graduate, PhD, and postgraduate students; and end users interested in membrane science and technology, nanomaterials, eco-friendly separation, chemistry, biology, and process engineering.
The need for batteries has grown exponentially in response to the increase in global energy demand and to the ambitious goals that governments have set up for sustainable energy development worldwide, especially in developed countries. While lithium-ion batteries currently dominate the energy storage market, the limited and unevenly distributed lithium resources have caused huge concerns over the sustainability of the lithium-ion battery technology. Sodium-ion batteries have significant benefits over lithium-ion batteries, including sodium's abundance in the Earth's crust. These batteries have therefore gained research interest, and efforts are being made to use them in place of lithium-ion batteries. While the past decade has witnessed significant research advances and breakthroughs in developing the sodium-ion battery technology, there still remain fundamental challenges that must be overcome to push the technology forward. This book comprises 13 chapters that discuss the fundamental challenges, electrode materials, electrolytes, separators, advanced instrumental analysis techniques, and computational methods for sodium-ion batteries from renowned scientists. The book is a unique combination of all aspects associated with sodium-ion batteries and can therefore be used as a handbook.
