Buch. Zustand: Neu. Neuware - This authoritative book on China's oil demand and government policies and practices rests on two essential foundations: first and foremost on the author's considerable knowledge of China's oil situation and prospects, together with his access to Chinese energy literature and data; and secondly, on that insight afforded to him and, therefore, his readers from his fluency in Chinese.The author analyzes the Chinese oil market and the rising pressure on Beijing to reform policies which constrain China's ability to meet soaring demand and to pay for crucial imports at a time of growing political and economic uncertainties. Dr Wang acknowledges the importance of China meeting its growing domestic oil demand, if at all possible, through national production. The sheer weight of China's population, and its burgeoning requirements as industrialization spreads into most regions, dwarfs the needs of others and places unprecedented strain on international oil trades.The author stresses the fact that the outcome is hard to define, yet the time required to tackle the nation's energy needs is not limitless. Moreover, he reminds the reader of the perennial difficulty in meeting widely disparate economic and energy needs in different regions of the vast country.…

Buch. Zustand: Neu. Neuware - This book is devoted to the interaction between elemental metals and (in)organic ligands in different reaction conditions. Metals could be activated for further reactions as cryosynthesis, electrosynthesis and tribosynthesis, some of them with or without ultrasonic and microwave treatment. The kinetics of metal dissolution in various non-aqueous media is discussed in detail.Many methods are used nowadays to synthesize coordination compounds. Metal complexes are obtained mainly by the direct interaction of the components (the ligands and a source of the complex-forming metal), as a result of ligand and metal exchange, and under the conditions of template synthesis, which also include the method of nascent reagents. In these methods the source of the metal is either its salts or carbonyls. At the same time, it has long been known that coordination compounds may be obtained as a result of direct synthesis from zero-valent metals. Methods for the synthesis of complex compounds under the conditions of gas-phase reactions, oxidative dissolution of zero-valent metals in non-aqueous media, and in the solid phase have been developed. These methods have become the basis of a new field in synthetic chemistry - the direct synthesis of coordination and organometallic compounds from zero-valent metals.Particular aspects of the above problem have been described in a series of reviews and monographs. However, on the whole these main parts of the direct synthesis of metal complexes has not been dealt with in the review and monograph publications on coordination chemistry. So, the main objective of this book is to analyze, discuss and generalize the existing information in the area of direct reactions leading to the coordination and organometallic reactions.Some methods of direct synthesis have been developed in the former USSR (in particular, a lot of works on cryosynthesis, pioneered (1972-1973) and recent works on electrosynthesis) but, in spite of their novelty and/or wide applicability, they are practically unknown elsewhere due to the language barrier. Thus, another objective of this book is to acquaint the readers with the mentioned achievements.Every chapter contains the tables which describe all the reported data on direct reaction between metal atoms, metal particles or bulk metals with (in)organic ligans. There are some illustrations also (for example, the scheme of the reactor for gas-phase reaction between metal small particles and &bgr;-diketones).…
