This book offers a broad coverage of the theory and practice of industrial microwave heating. It introduces the physical processes behind dipolar and conductivity loss mechanisms and follows with a thorough presentation of dielectric property data of many industrial materials as a function of the moisture content, temperature and frequency, focussing on the interpretation of such data as regards the suitabiliy for processing these materials with microwave energy. The basic equations which govern the power dissipation, attenuation, phase constant, penetration depth and skin depth are derived from first principles while the transport equations of heat, mass and pressure are qualitatively described, giving particular emphasis to the physical mechanisms behind high frequency drying. The book provides established procedures backed by theoretical formulations for the design of industrial travelling wave and multimode applicators. It also provides extensive coverage of single mode fundamental or higher order resonant cavities and outlines a number of atypical applicator structures. It describes the essential features of processing with microwaves under vacuum and presents a brief introduction to the mechanisms which lead to gas breakdown. It stresses the need for a degree of hybridisation with other electrical or conventional heating systems and discusses a few such schemes. The book outlines a number of systems for limiting leakage from on-line industrial microwave systems and concludes with an extensive discussion of successful industrial applications.

Microwaves can be effectively used in the processing of industrial materials under a wide range of conditions. However, microwave processing is complex and multidisciplinary in nature, and a high degree of technical knowledge is needed to determine how, when, and where the technology can be most profitably utilized. This book assesses the potential of microwave technology for industrial applications, reviews the latest equipment and processing methods, and identifies both the gaps in understanding of microwave processing technology and the promising development opportunities that take advantage of this new technology's unique performance characteristics.

More than 80 years of experience in the practical application of electromagnetic energy in various fields of human activity (industry, agriculture, science, medicine, etc.) suggests that microwave heating is an effective application of electromagnetic energy. This book presents the latest investigations on the applications of microwave energy and the effects of microwave radiation on various materials and mediums. Divided into two sections on thermal and nonthermal effects, this volume contains eight chapters that examine the use of microwave energy to extract bioactive compounds from plant materials, for rock-breaking operations, to synthesize functional dyes and nanomaterials, and more.

Using microwaves to treat metal-based materials is rapidly emerging as an energy-efficient tool to interact with metals for a number of processes such as sintering, melting, brazing, carburizing and annealing. Microwaves can sinter a wide variety of metal compacts with comparable or enhanced end properties, while at the same time delivering tremendous energy savings over conventional sintering. Microwave processes are therefore gaining increasing attention and adoption in both academia and industry. Gupta and Wong have written this comprehensive text to introduce readers to the world of microwaves and the interaction of microwaves with metals and metals-based formulations. The authors have combined numerous research results from a wide range of sources alongside their own work in the field. Also included are overviews of microwave heating of other non-metal materials and the equipment used for microwave-assisted metallurgy. With microwave techniques poised for widespread adoption, Microwaves and Metals is an essential text for all metallurgists and materials engineers. Provides a thorough grounding in microwave fundamentals and their application to metals processing Informs readers of the latest developments in the field Presents a convenient single source for all aspects of microwave processing of metals and materials Contains liberal illustration to compare and benchmark research results Introduces all the necessary equipment, preparing readers for real-world practice Microwaves and Metals is ideal for a post-graduate or advanced undergraduate course in materials science or metallurgy. Materials and metallurgical engineers in industry, who are keen on cheaper, faster techniques, will also benefit from this book.

Microwave-Assisted Sample Preparation for Trace Element Analysis, Second Edition, describes the principles, equipment, and applications involved in sample preparation with microwaves for detecting and analyzing trace elements. Hot topics such as sample preparation for speciation, metabolomics, and halogen determination, as well as the alternatives of sample preparation for special samples (for example, carbon nanotubes, polymers, petroleum products), are also discussed. This completely updated second edition covers all the new devices and more powerful systems that have emerged in the last several years, such as Ultrawave and Ultraclave systems. New challenges in the fields of geology, environmental and biological studies -for example, the need for further determination of rare earth elements and halogens - are currently only covered in scientific journals and not in a comprehensive way. This book offers a summary of the state-of-the-art ways to meet these challenges with microwave-assisted sample preparation. The only book to cover in depth the principles, equipment, and applications of microwave-assisted sample preparation Written by experts in the field who provide a comprehensive overview of the important concepts Introduces the latest devices and systems used for in microwave-assisted techniques, including Ultrawave and Ultraclave systems

This volume looks at modern approaches to catalysis and reviews the extensive literature. Chapters highlight application of 2D materials in biomass conversion catalysis, plasmonic photocatalysis, catalytic demonstration of mesoporosity in the hierarchical zeolite and the effect of surface phase oxides on supported metals and catalysis. Looking to the future a chapter on ab initio machine learning for accelerating catalytic materials discovery is included. Appealing broadly to researchers in academia and industry, these illustrative chapters bridge the gap from academic studies in the laboratory to practical applications in industry not only for catalysis field but also for environmental protection. Other chapters with an industrial perspective include heterogeneous and homogeneous catalytic routes for vinyl acetate synthesis, catalysis for production of jet fuel from renewable sources by HDO/HDC and microwave-assisted catalysis for fuel conversion. Chemical reactions in ball mills is also explored. The book will be of great benefit to any researcher wanting a succinct reference on developments in this area now and looking to the future.

Did you know the microwave oven was actually invented by mistake? While experimenting with electricity, a scientist noticed the chocolate snack he had in his pocket actually melted. This led to the technology that has made cooking faster, more convenient, and used more than conventional cooking. This book addresses the differences between a standard oven, which uses conduction, and a microwave oven, which uses microwaves, causing food molecules to move, creating heat. The more the molecules move, the hotter the food gets. So, pop in a snack, set the timer, and in a few seconds you’ll be ready to enjoy! This book will allow students to plan and conduct an investigation to determine the effect of placing objects made with different materials in the path of a beam of light.
