Scientists in such fields as mathematics, physics, chemistry, biochemistry, biology, and medicine are currently involved in investigations of porphyrins and their numerous analogues and derivatives. Porphyrins are being used as platforms for the study of theoretical principles, as catalysts, as drugs, as electronic devices, and as spectroscopic probes in biology and medicine. The need for an up-to-date and authoritative treatise on the porphyrin system has met with universal acclaim amongst scientists and investigators.
Lithium Batteries: Science and Technology is an up-to-date and comprehensive compendium on advanced power sources and energy related topics. Each chapter is a detailed and thorough treatment of its subject. The volume includes several tutorials and contributes to an understanding of the many fields that impact the development of lithium batteries. Recent advances on various components are included and numerous examples of innovation are presented. Extensive references are given at the end of each chapter. All contributors are internationally recognized experts in their respective specialty. The fundamental knowledge necessary for designing new battery materials with desired physical and chemical properties including structural, electronic and reactivity are discussed. The molecular engineering of battery materials is treated by the most advanced theoretical and experimental methods.
Explains the current state of the science and points the way to technological advances First developed in the late 1980s, lithium-ion batteries now power everything from tablet computers to power tools to electric cars. Despite tremendous progress in the last two decades in the engineering and manufacturing of lithium-ion batteries, they are currently unable to meet the energy and power demands of many new and emerging devices. This book sets the stage for the development of a new generation of higher-energy density, rechargeable lithium-ion batteries by advancing battery chemistry and identifying new electrode and electrolyte materials. The first chapter of Lithium Batteries sets the founda...
An examination of applications of electrochemical techniques to many organic and inorganic compounds that are either unstable or insoluble in water. It focuses on the continuing drive toward miniaturization in electronics met by designs for high-energy density batteries (based on nonaqueous systems). It addresses applications to nonaqueous batteries, supercapacitators, highly sensitive reagents, and electroorganic and electroinorganic synthesis.
The main aim of this book is to provide a complete picture of current research on phosphazene compounds carried out around the world. The book opens with a general introduction, then moves on to cover synthetic aspects of phosphazene polymers, their characterization in solution and from the theoretical, thermal, and mechanical points of view; application aspects of poly(organophosphazenes); and the synthesis, characterization, and practical utilization of cyclophosphazenes. There is particular focus on the use of cyclophosphazenes as hydraulic fluids and additives, as cores for star polymers or dendrimers, and as starting substrates for supramolecular chemistry and nanostructured materials. The spectroscopic characterization of these compounds by NMR and Raman techniques is also discussed. Annotation : 2004 Book News, Inc., Portland, OR (booknews.com).

Energy production and storage are central problems for our time. In principle, abundant energy is available from the sun to run the earth in a sustainable way. Solar energy can be directly harnessed by agricultural and photovoltaic means, but the sheer scale of the energy demand poses severe challenges, for example any major competition between biomass production and food production would simply transfer scarcity from energy to food. Indirect use of solar energy in the form of wind looks also promising, especially for those regions not blessed with abundant sunlight. Other modes such as tidal and wave energy may well become important niche players. Inorganic chemistry plays a decisive role i...
This book is about how to avoid the accidents and injuries that may occur when batteries are abused or mishandled. It is the first book to deal specifically with this subject in a reasonably comprehensive manner accessible to readers ranging from regular consumers to technical specialists. Batteries and battery processes are described in sufficient detail to enable readers to understand why and how batteries cause accidents and what can be done to prevent them. Each year in the United States alone, thousands of individuals are injured by battery accidents, some of which are severely disabling. The tragedy is that such accidents need not occur. The book is intended to satisfy the needs of a varied group of readers: battery users in general, battery engineers, and designers of battery-operated equipment and consumer electronics. Since the book is a reference source of information on batteries and battery chemicals, we believe it may also be useful to those studying the environment as well as to medical personnel called upon to treat battery injuries. There are no prerequisites for an under standing of the text other than an interest in batteries and their safe usage.
