Hydrothermal and Supercritical Water Processes presents an overview on the properties and applications of water at elevated temperatures and pressures. It combines fundamentals with production process aspects. Water is an extraordinary substance. At elevated temperatures (and pressures) its properties change dramatically due to the modifications of the molecular structure of bulk water that varies from a stable three-dimensional network, formed by hydrogen bonds at low and moderate temperatures, to an assembly of separated polar water molecules at high and supercritical temperatures. With varying pressure and temperature, water is turned from a solvent for ionic species to a solvent for polar and non-polar substances. This variability and an enhanced reactivity of water have led to many practical applications and to even more research activities, related to such areas as energy transfer, extraction of functional molecules, unique chemical reactions, biomass conversion and fuel materials processing, destruction of dangerous compounds and recycling of useful ones, growth of monolithic crystals, and preparation of metallic nanoparticles. This book provides an introduction into the wide range of activities that are possible in aqueous mixtures. It is organized to facilitate understanding of the main features, outlines the main applications, and gives access to further information Summarizes fundamental properties of water for engineering applications Compares process and reactor designs Evaluates processes from thermodynamic, economic, and social impact viewpoints



Topical Themes in Energy and Resources

This book combines issues several critical ones in the energy field (low-energy technologies, renewable energies such as the hydrogen economy, and geothermal energy). Moving towards a more sustainable world requires a complete revolution in the way we manage energy and resources. However, from an academic perspective, this theme is so broad that most educators and researchers tend to focus on just one aspect, and maintaining the broad viewpoint which is necessary for making strategic judgments becomes difficult. Tohoku University addressed this challenge when developing a new education and training program for environmental leaders and brought together the extensive range of expertise available in specific fields into one special course which forms the basis of this book. Now in one volume, both students and educators can be brought up to date on a wide range of critical issues currently being addressed in the field of energy and resources. Chapters on resources include availability (for instance, rare earth metals), extraction and recycling of metals and plastics, and technological solutions to specific waste-disposal problems. In addition, broader strategic issues such as limits to growth and the interaction between the economic system and environmental issues are addressed. Even though each chapter provides topical data and knowledge from disparate and specialized fields, the book is written at a level that is readily understandable by students from all scientific, engineering, and humanities fields.

In situ Spectroscopic Techniques at High Pressure provides a comprehensive treatment of in-situ applications of spectroscopic techniques at high pressure and their working principles, allowing the reader to develop a deep understanding of which measurements are accessible with each technique, what their limitations are, and for which application each technique is best suited. Coverage is also given to the instrumental requirements for these applications, with respect to the high pressure instrumentation and the spectroscopic components of the equipment. The pedagogical style of the book is supplemented by the inclusion of "study questions" which aim to make it useful for graduate-level courses. Bridges the gap between supercritical fluid science/technology and in-situ spectroscopic techniques Provides a powerful guide to applying spectroscopic techniques as gainful sensors at high pressure Highlights the influence of a high pressure environment and high pressure equipment on spectroscopic techniques Presents a deep understanding of which measurements are accessible with each technique, what their limitations are, and for which application each technique is best suited

This book will review the current status of the agriculture and agri-food sector in regard to green processing and provide strategies that can be used by the sector to enhance the use of environmentally-friendly technologies for production, processing. The book will look at the full spectrum from farm to fork beginning with chapters on life cycle analysis and environmental impact assessment of different agri-food sectors. This will be followed by reviews of current and novel on-farm practices that are more environmentally-friendly, technologies for food processing that reduce chemical and energy use and emissions as well as novel analytical techniques for R&D and QA which reduce solvent, chemical and energy consumption. Technologies for waste treatment, "reducing, reusing, recycling", and better water and energy stewardship will be reviewed. In addition, the last section of the book will attempt to look at technologies and processes that reduce the generation of process-induced toxins (e.g., trans fats, acrylamide, D-amino acids) and will address consumer perceptions about current and emerging technologies available to tackle these processing and environmental issues.

This book is a systematic compilation of the most recent body of knowledge in the rapidly developing research area of greenhouse gas interaction with clay systems. Unexpected results of the most recent studies – such as unusually high sorption capacity and sorption hysteresis of swelling clays –stimulated theoretical activity in this fascinating field. Classical molecular dynamics (MD) explains swelling caused by intercalation of water molecules and to a certain degree of CO2 molecules in clay interlayer. However, unusual frequency shifts in the transient infrared fingerprints of the intercalated molecules and the following accelerated carbonation can be tackled only via quantum mechanical modeling. This book provides a streamlined (from simple to complex) guide to the most advanced research efforts in this field.

This book deals with theoretical aspects of modelling the mechanical behaviour of manufacturing, processing, transportation or other systems in which the processed or supporting material is travelling through the system. Examples of such applications include paper making, transmission cables, band saws, printing presses, manufacturing of plastic films and sheets, and extrusion of aluminium foil, textiles and other materials. The work focuses on out-of-plane dynamics and stability analysis for isotropic and orthotropic travelling elastic and viscoelastic materials, with and without fluid-structure interaction, using analytical and semi-analytical approaches. Also topics such as fracturing and fatigue are discussed in the context of moving materials. The last part of the book deals with optimization problems involving physical constraints arising from the stability and fatigue analyses, including uncertainties in the parameters. The book is intended for researchers and specialists in the field, providing a view of the mechanics of axially moving materials. It can also be used as a textbook for advanced courses on this specific topic. Considering topics related to manufacturing and processing, the book can also be applied in industrial mathematics.
