Taschenbuch. Condizione: Neu. Neuware - Molecular Physical Chemistry: A Concise Introduction focuses on two main aspects of physical chemistry: thermodynamics and reaction dynamics. By looking at the properties of the atoms and molecules that constitute matter, it makes use of results from modern experiments conducted on small numbers of molecules. These molecular properties allow the behaviour of larger groups of molecules to be predicted. This is in contrast to conventional approaches which are based upon how the subjects have developed historically. It attempts to show how some basic concepts can be easily applied to give verifiable results in simple systems before extending them to more complicated scenarios.The text is intended as an aid to understanding these central topics of physical chemistry, rather than an introduction to them, and some familiarity with them is assumed throughout. Worked examples and problems are given at the end of each chapter. Molecular Physical Chemistry: A Concise Introduction will be welcomed by graduate and advanced undergraduate students, as well as lecturers. Upon completion of this book the reader will see its subject matter as an integral part of their whole approach to chemistry. TOC:Some Basic Ideas and Examples.- Partition Functions.- Thermodynamics.- Applications.- Reactions.- Answers to Problems.- Some Useful Constants and Relations.- Subject Index.

Buch. Condizione: Neu. Neuware - Clean Energy presents a broad survey of the energy problems facing society over the coming decades and the prospects for their solution.The book emphasizes the importance of developing a strategy for the world's future energy supply. The strategy must take into account: the finite supplies of natural gas and petroleum; the increased consumption of fuel by developing economies; the concern over greenhouse gas emissions; the pollution caused by burning coal (especially coal with a high sulphur content); the difficulties and costs of extracting unconventional fossil fuels; and the technical, sociological and cost barriers that restrict the use of renewable forms of energy.Clean Energy sets the various renewable energies (wind, waves, solar etc) in the context of present and projected world production of energy usage in the time-frame until 2020 and looks speculatively beyond that. It looks at the possibilities for reducing pollution from fossil fuels and tackles the serious problem of how to store energy, in order to smooth out fluctuations in supply and demand.Clean Energy is well illustrated with diagrams and photographs and will appeal to anyone with a serious interest in environmental matters and in the interaction between energy usage and the environment.
