An exhaustive and timely overview of renewable polymers from a respected chemist and successful author The recent explosion of interdisciplinary research has fragmented the knowledge base surrounding renewable polymers. The Chemistry of Bio-based Polymers brings together, in one volume, the research and work of Professor Johannes Fink, focusing on biopolymers that can be synthesized from renewable polymers. After introducing general aspects of the field, the book’s subsequent chapters examine the chemistry of biodegradable polymeric types sorted by their chemical compounds, including the synthesis of low molecular compounds. Various categories of biopolymers are detailed including vinyl-based polymers, acid and lactone polymers, ester and amide polymers, carbohydrate-related polymers and others. Procedures for the preparation of biopolymers and biodegradable nanocomposites are arranged by chemical methods and in vitro biological methods, with discussion of the issue of “plastics from bacteria.” The factors influencing the degradation and biodegradation of polymers used in food packaging, exposed to various environments, are detailed at length. The book covers the medical applications of bio-based polymers, concentrating on controlled drug delivery, temporary prostheses, and scaffolds for tissue engineering. Professor Fink also addresses renewable resources for fabricating biofuels and argues for localized biorefineries, as biomass feedstocks are more efficiently handled locally. Audience The Chemistry of Bio-based Polymers will be read by chemists, polymer and materials scientists, chemical, bio-based, and biomedical engineers, agricultural and environmental faculty and all those who work in the bioeconomy area. This book will be critical for engineers in a number of industries including food packaging, medical devices, personal care, fuels, auto, and construction.

This book presents methods for the design of the main microwave active devices. The first chapter focuses on amplifiers working in the linear mode. The authors present the problems surrounding narrowband and wideband impedance matching, stability, polarization and the noise factor, as well as specific topologies such as the distributed amplifier and the differential amplifier. Chapter 2 concerns the power amplifier operation. Specific aspects on efficiency, impedance matching and class of operation are presented, as well as the main methods of linearization and efficiency improvement. Frequency transposition is the subject of Chapter 3. The author presents the operating principle as well as the different topologies using transistors and diodes. Chapter 4 is dedicated to the operation of fixed frequency and tunable oscillators such as the voltage controlled oscillator (VCO) and the yttrium iron garnet (YIG). The final chapter presents the main control functions, i.e. attenuators, phase shifters and switches.

The authors describe a technique that can visualize the atomic structure of molecules, it is necessary, in terms of the image processing, to consider the reconstruction of sparse images. Many works have leveraged the assumption of sparsity in order to achieve an improved performance that would not otherwise be possible. For nano MRI, the assumption of sparsity is given by default since, at the atomic scale, molecules are sparse structures. This work reviews the latest results on molecular imaging for nano MRI. Sparse image reconstruction methods can be categorized as either non-Bayesian or Bayesian. A comparison of the performance and complexity of several such algorithms is given.

The acute energy problems facing China today are characterized by their own histories and realities. Some have come about because of China's energy endowment and stage of development, while others have been created by a combination of domestic and global factors. Some are the results of an accumulation of longstanding contradictions, while others are new challenges posed by the new order. There are no «miracle cures» to solve these problems instantly. What is needed is a tireless enquiry, with goals, planning and procedures, guided by a clear energy strategy. With China's increasing dependence on foreign energy sources, and the global energy situation and greenhouse gas issue exerting an increasingly prohibiting effect on China's energy development, energy diplomacy has become an important component of Chinese diplomatic affairs. Based on a «broad energy outlook», this book studies and analyzes China's energy issues and energy strategies from the perspective of electric power. Discusses a variety of issues, including energy transportation and allocation, end-user consumption, markets, early warning and emergency, technical innovation As a leading player in the power and energy area, China’s strategies attracts global attention Proposes the innovative idea of «Macro Energy Perspective» As a key player in China's energy industrial circle, the author's perspective can help global audiences to understand China's energy strategies better Electric Power and Energy in China is ideal for government energy policy makers, engineers, scientists and enterprise managers to understand China’s strategy in electric power and energy. It is also a good reference for energy economics researchers, consultants and university students.
