Polymer matrix composites are finding increasing number of applications due to their high weight-saving potential as well as unique characteristics, such as high strength-to-density ratio, fatigue resistance, high damping factor, and freedom from corrosion. While many textbooks are available on the mechanics of polymer matrix composites, few cover their processing.Processing of Polymer Matrix Composites fills this gap. The book focuses on the major manufacturing processes used for polymer matrix composites and describes process details, process parameters and their effects on properties and process-induced defects, and analytical and experimental methods used for understanding process conditions. The book describes fibers, thermosetting and thermoplastic polymers, and interface characteristics that are important from the standpoint of both design and processing. It also emphasizes the applications of process fundamentals for both continuous fiber and short fiber polymer matrix composites. In addition the book considers quality inspection methods, tooling, and manufacturing costs and environmental and safety issues.

In the near future, many parts of the world will suffer from a shortage of freshwater. Effective use of seawater in concrete production could therefore become a crucial technology. Seawater in Concrete Mix provides a detailed overview of the fundamental knowledge of concrete engineering that is essential for the usage of seawater-mixed concrete. According to the worldwide standard for reinforced concrete (RC), freshwater is typically used in concrete mixing rather than seawater. Yet a potential exists for the extensive use of seawater in concrete, especially with the addition of ground granulated blast-furnace slag, fly ash, or other mineral admixtures. The recent trend toward performance-based design makes this alternative more viable. The text is ideal for graduate students, researchers, concrete engineers, and all civil engineers who deal with concrete for infrastructure. Hidenori Hamada is Professor of Kyushu University, Japan. Nobuaki Otsuki is Professor Emeritus of Tokyo Institute of Technology and was Chairman of the JCI Technical Committee on the use of seawater in concrete. Takahiro Nishida is Senior Researcher of the Japanese National Institute of Maritime, Port and Aviation Technology.

As it results from the very nature of things, the spherical symmetry of the surrounding of a site in a crystal lattice or an atom in a molecule can never occur. Therefore, the eigenfunctions and eigenvalues of any bound ion or atom have to differ from those of spherically symmetric respective free ions. In this way, the most simplified concept of the crystal field effect or ligand field effect in the case of individual molecules can be introduced.
The conventional notion of the crystal field potential is narrowed to its non-spherical part only through ignoring the dominating spherical part which produces only a uniform energy shift of gravity centres of the free ion terms. It is well understood that the non-spherical part of the effective potential "seen" by open-shell electrons localized on a metal ion plays an essential role in most observed properties. Light adsorption, electron paramagnetic resonance, inelastic neutron scattering and basic characteristics derived from magnetic and thermal measurements, are only examples of a much wider class of experimental results dependent on it. The influence is discerned in all kinds of materials containing unpaired localized electrons: ionic crystals, semiconductors and metallic compounds including materials as intriguing as high-"Tc" superconductors, or heavy fermion systems. It is evident from the above that we deal with a widespread effect relative to all free ion terms except those which can stand the lowered symmetry, e.g. "S"-terms.
Despite the universality of the phenomenon, the available handbooks on solid state physics pay only marginal attention to it, merely making mention of its occurrence. Present understanding of the origins of the crystal field potential differs essentially from the pioneering electrostatic picture postulated in the twenties. The considerable development of the theory that has been put forward since then can be traced in many regular articles scattered throughout the literature. The last two decades have left their impression as well but, to the authors' best knowledge, this period has not been closed with a more extended review. This has also motivated us to compile the main achievements in the field in the form of a book.

Over three billion metric tons of cement are produced annually worldwide, making concrete the most extensively used construction material. Self-sensing, or smart, cement allows real-time monitoring of performance through the entire service life of a concrete structure, for the detection of changing stresses, contamination, excessive temperature, gas leaks and pre-seismic activity. This is achieved by adding a very small proportion of conductive or semi-conductive fibers, such as carbon fibers to the bulk cement, making it piezoresistive, and enabling changes in the concrete's electrical resistivity in response to shear stress and strain to be monitored. This state-of-the-art reference work presents experimental results with a realistic theoretical framework, for cement manufactures, concrete technologists and contractors as well as researchers.

Renewable energies have become an attractive option to overcome the energy demands in sustainable and affordable ways. It has been estimated that one-third of the total renewable energies would be generated from photovoltaics (PVs). A solar or PV cell is a device that directly converts sunlight into electricity by taking benefit of the photoelectric effect. In the third-generation solar PVs, dye-sensitized solar cells (DSSCs) are believed to be the most promising and have attracted wide attention. The optimization of a DSSC is focused on four main components: (i) metal oxide semiconductor, (ii) photosensitizer, (iii) redox couple electrolyte, and (iv) counter electrode. Among these, the counter electrode undertakes three functions: (i) as a catalyst, (ii) as a positive electrode of primary cells, and (iii) as a mirror. To obey these functions, the electrode material should have high catalytic activity, high conductivity, high reflectivity, high surface area, and electrochemical and mechanical stability. To improve the performance of DSSCs, many scientists have developed new counter electrodes made of platinum, carbon materials, transition metals, conductive polymers, and composites. This book converses the various aspects of materials for the fabrication of counter electrodes especially for the DSSCs.

Semiconducting polymers are of great interest for applications in electroluminescent devices, solar cells, batteries, and diodes. This volume provides a thorough introduction to the basic concepts of the photophysics of semiconducting polymers as well as a description of the principal polymerization methods for luminescent polymers. Divided into two main sections, the book first introduces the advances made in polymer synthesis and then goes on to focus on the photophysics aspects, also exploring how new advances in the area of controlled syntheses of semiconducting polymers are applied. An understanding of the photophysics process in this kind of material requires some knowledge of many different terms in this field, so a chapter on the basic concepts is included. The process that occurs in semiconducting polymers spans time scales that are unimaginably fast, sometimes less than a picosecond. To appreciate this extraordinary scale, it is necessary to learn a range of vocabularies and concepts that stretch from the basic concepts of photophysics to modern applications, such as electroluminescent devices, solar cells, batteries, and diodes. This book provides a starting point for a broadly based understanding of photophysics concepts applied in understanding semiconducting polymers, incorporating critical ideas from across the scientific spectrum.

Surface Chemistry of Carbon Capture: Climate Change Aspects provides comprehensive and up-to-date literature on carbon capture and storage (CCS) technology and delineates the surface chemistry of this process. Mankind is dependent on energy from gas, oil, coal, atomic energy, and various other sources. In all fossil fuel combustion processes, carbon dioxide (CO2) is produced (ca. 25 Gt/year). In the past few decades, we have observed a constant increase in CO2 content in the air (currently ca. 400 ppm [0.04%]). This book discusses the technology related to carbon (i.e., CO2) capture and sequestration (CCS) from fossil fuel energy plants, which is considered an important means of CO2 control. It also covers the adsorption/absorption processes of CO2 on solids and similar procedures to help address growing climate change concerns.

Chloride-induced corrosion is the most important durability issue of reinforced concrete structures, and the prediction and prevention of chloride-induced corrosion has attracted considerable interest all over the world. Given that chloride penetrates through the concrete cover, the issues concerning its transport are crucial. These include testing methods, prediction, and the prevention of ingress. During the transport process, physical and chemical interaction occurs between chloride and cement hydrates, which in turn affects the further transport, so the transport of chloride and these interactions are closely related and underpin our understanding of chloride-induced corrosion in RC structures. This book provides in-depth discussion of chloride transport and its interaction in cement-based materials, and reviews and summarizes the state of the art. The mechanisms and testing methods for chloride transport, chemical interactions of chloride with cement hydrates, chloride binding isotherms, measurement of penetration depths, factors affecting chloride transport, and modeling of chloride transport are discussed in detail. This book serves as a reference for researchers or engineer, and a textbook for graduate students.

It concentrates on properties of each class of chalcogenadiazoles and their cycle-fused derivatives, considering chemical reactions of functional groups only in cases when these reactions permit to characterize the heterocycles as substituents or in respect of its aromaticity.Covering an important and rapidly developing branch of heterocyclic chemistry, this book is an essential resource for students, young professionals and experienced specialists in adjacent fields who are interested in: Trends in the search for compounds with established bioactivity or use in medicine, as agrochemicals, or as reagents for environmental and biochemical analysis Differences in classes of chalcogenadiazoles with respect to their degree of aromaticity and similar general concepts helpful to the nonspecialist The effects of the chalcogen nature and the alternation manner of all atomic constituents on properties of these heterocyclic compounds Combining data from organic, biological, medicinal, materials science, and supramolecular chemistry, Chalcogenadiazoles: Chemistry and Applications is an important source of information not only for chemists in the fields of organic, inorganic, and organometallic chemistry, but also for anyone interested in the research and development of chalcogenadiazoles and related species.

From the Preface The purpose of this book is to present within a single volume, detailed information concerning the science, processing, applications, characterization and properties of composite materials reinforced with short fibres that have been oriented in a preferred direction by flows arising during processing. This book is intended to be useful to . . . materials scientists and other specialists in the field . . . and engineers, designers and producers of composites reinforced with short fibres. To our knowledge, this is the first time information pertaining to this important class of engineering materials has been systematically presented within a single volume. The purpose of aligning short fibres in a fibre-reinforced material is to improve the mechanical properties of the resulting composite. Aligning the fibres, generally in a preferred direction, allows them to contribute as much as possible to reinforcing the material. In some instances, the mechanical properties of these aligned, short-fibre composites can approach those of continuous-fibre composites, with the added advantage of low production costs and greater ease of production. The book covers theory, processing, characterization and properties. More specifically, the topics considered . . . include fibre alignment and material rheology; processes that can produce fibre alignment in polymeric, liquid crystal polymeric and metallic composites; materials characterization and mechanical properties; and modelling of processes and material properties.
