  • Direct Synthesis of Coordination and Organometallic Compounds

    • 1st Edition
    • A.D. Garnovskii + 1 more
    • English
    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)...

  • Experiments in Catalytic Reaction Engineering

    • English
    The science of catalytic reaction engineering studies the catalyst and the catalytic process in the laboratory in order to predict how they will perform in production-scale reactors. Surprises are to be avoided in the scaleup of industrial processes. The laboratory results must account for flow, heat and mass transfer influences on reaction rate to be useful for scaleup. Calculated performance based on these results must also be useful to maximization of profit and safety and minimization of pollution. To this end, information on products as well as byproducts and heat produced must be generated. If a sufficiently large database of knowledge is produced, optimization studies will be possible later if economic conditions change.The field of reaction engineering required new tools. For kinetic and catalyst testing, the most successful of these tools was the internal recycle reactor. Studies in recycle reactors can be made under well-defined conditions of flow and associated transfer processes, and close to commercial operation. The recycle reactor eliminates or minimizes the effect of transfer process, and allows the remaining ones to be known.Features of this book:• Provides insight into a field that is neither well understood nor properly appreciated.• Gives a deeper understanding of reaction engineering practice.• Helps avoid frustration and disappointment in industrial research. This book is short and clear enough to assist all members of the R&D and Engineering team, whether reaction engineers, or specialists in other fields. This is critical in this new age of computation and communication, when team members must each know at least something of their colleagues' fields. Additionally, many scientists in more exploratory or fundamental fields can use recycle reactors to study basic phenomena free of transfer interactions.

  • Molecular Photonics for Optical Telecommunications: Materials, Physics and Device Technology

    Symposium M of the 1998 annual meeting of the European Materials Research Society has been devoted to Molecular Photonics for Optical Communications: Materials, Physics and Device Technology. It was held in Strasbourg from 15-19 June, building on the sizable success of the former symposium Molecular Electronics and Photonics, held during the last 1997 E-MRS meeting. A total of 42 oral and 36 poster presentations were delivered at this symposium. A most remarkable common feature to almost all papers presented concerned a very broad approach which was given to this particular field of Materials Science, starting at the borderlines between chemistry and physics, photonics and electronics, from their most fundamental aspects all the way to technology and device engineering considerations.The manuscripts have been gathered in four main areas. First and foremost, we brought together the papers encompassing the growing area of Device Physics and Technology, to reflect the emphasis given during this symposium to the crucial application aspect of this theme of Materials Science. The second chapter presents the most recent advances achieved in the field of Luminescent Structures, which is one of the most active research areas in the field of (macro)molecular-bas... optoelectronics and lasing materials aiming at the realization of a polymer-based laser diode. The third chapter, demonstrates recent advances in the field of Photonic Structures, whereby the most recent achievements have been brought to the attention of the scientific community, particularly in the realms of photorefractive polymers and nonlinear integrated optics devices. Finally the fourth chapter presents a very basic understanding of Organic Solid State Properties, such as pertain to optically detected magnetic resonance or photo-conductivity studies.Among the foremost conclusions to be drawn from the papers in both oral and poster sessions, the huge progress which has been accomplished towards the fabrication of real devices stands-out as a most noteworthy feature: this clearly signals to the organic community and hopefully much beyond, that molecular materials and associated devices have matured considerably in terms of fabrication technologies, stability and lifetime issues, as well as for the fundamental understanding of their properties.

    The Symposium on 'Nitrides and related wide band gap materials' at the 1998 Spring Meeting of the European Materials Research Society (E-MRS) in Strasbourg, France, was the third Symposium of its kind at an E-MRS meeting. Beginning in 1996, these Symposia enjoyed a steadily increasing popularity among European and international nitride researchers.Contribu... covered the areas of hetero-epitaxy, bulk growth, structural, electrical and optical characterisation and device fabrication. Researchers from about 20 different countries presented their work at this symposium. Naturally, most papers were from within Europe (Germany, France, Russia and the United Kingdom) but there was also a remarkable number of contributions from overseas (USA, Japan and Korea.)For about 5 years now, semiconducting group-III nitrides have attracted an enormous level of research activity all over the world. Essentially this was triggered by the breakthroughs achieved by Shuji Nakamura and his group in Japan, who succeeded in making highly efficient blue, green and yellow light emitting diodes as well as violet laser diodes based on A1GaInN. Since then, intensive research related to material growth, device development, as well as to the fundamental properties of these materials is being carried out.The outstanding contribution of Shuji Nakamura to this field was underlined by his plenary lecture during this E-MRS meeting. He presented his most recent progress towards amber LED's and long-lived violet laser diodes.

  • China's Oil Industry and Market

    • 1st Edition
    • H.H. Wang
    • English
    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.

    With the gradual development of rules for designing against instability the idea emerged, in London, in 1974 to hold an International Colloquium treating every aspect of structural instability of steel structures.There have been 17 International Colloquia Stability Sessions around the world, starting with the first one in Paris in 1972, until with the last one in Nagoya in 1997. In Nagoya it was decided to continue the series of travelling colloquia by launching the Sixth Colloquium in September 1999 with the First Session to be held at the "Politehnica" University of Timişoara, România, which will be followed by another in the year 2000 at the Gediminas Technical University in Vilnius, Lithuania, a third one during SSRC's Year 2000 Annual Meeting in the US, and a fourth one in Australia or New Zealand.At present important research projects are in progress around the world, like SAC Joint Venture Project in USA, INCO-COPERNICUS "RECOS" in Europe and others, which are devoted to improve and develop new methods for the safety design of steel structures in seismic zones. Special attention is paid in Europe, USA and Japan to improve the design codes and detailing of seismic resistant steel structures.This was the reason to organise the Session of Nagoya as "Stability and Ductility of Steel Structures" Colloquium. Romania is also a strong seismic territory and therefore, the topic of the Timişoara Session covered both stability and ductility problems. The technical programme of the SDSS'99 Colloquium in Timişoara has been split into nine working sessions.

    To leave our planet liveable in the next millennium mankind is forced to find environmentally friendly ways in solving the problems of everyday life. Among others, technologies of producing chemicals, absolutely necessary for maintaining a comfortable life, have to be modified, in some instances fundamentally changed now, or in the very near future.Developing new technologies requires strong and innovative fundamental research. In order to provide opportunity for crossfertilization the Federation of European Zeolite Associations (FEZA) decided to organise a conference, where researchers from academia as well as industry can meet, exchange ideas, show and discuss research efforts and results concerning the development of environmentally friendly processes and technologies.The conference, and thus the proceedings are divided into two main parts. The first part contains works concerning the synthesis, modification and characterisation of zeolitic materials as catalyst candidates in environmentally friendly technologies. Works in the second part describe various applications starting from developing highly selective reactions for the fine chemical industry, through waste-water treatment to applying zeolite for formulating bacteria for pest control.

  • Carbon Materials for Advanced Technologies

    • 1st Edition

    The inspiration for this book came from an American Carbon Society Workshop entitled "Carbon Materials for Advanced Technologies" which was hosted by the Oak Ridge National Laboratory in 1994. Chapter 1 contains a review of carbon materials, and emphasizes the structure and chemical bonding in the various forms of carbon, including the four allotropes diamond, graphite, carbynes, and the fullerenes. In addition, amorphous carbon and diamond films, carbon nanoparticles, and engineered carbons are discussed. The most recently discovered allotrope of carbon, i.e., the fullerenes, along with carbon nanotubes, are more fully discussed in Chapter 2, where their structure-property relations are reviewed in the context of advanced technologies for carbon based materials. The synthesis, structure, and properties of the fullerenes and nanotubes, and modification of the structure and properties through doping, are also reviewed. Potential applications of this new family of carbon materials are considered.The manufacture and applications of adsorbent carbon fibers are discussed in Chapter 3. The manufacture, structure and properties of high performance fibers are reviewed in Chapter 4, and the manufacture and properties of vapor grown fibers and their composites are reported in Chapter 5. The properties and applications of novel low density composites developed at Oak Ridge National Laboratory are reported in Chapter 6.Coal is an important source of energy and an abundant source of carbon. The production of engineering carbons and graphite from coal via a solvent extraction route is described in Chapter 7. Applications of activated carbons are discussed in Chapters 8-10, including their use in the automotive arena as evaporative loss emission traps (Chapter 8), and in vehicle natural gas storage tanks (Chapter 9). The application of activated carbons in adsorption heat pumps and refrigerators is discussed in Chapter 10. Chapter 11 reports the use of carbon materials in the fast growing consumer electronics application of lithium-ion batteries. The role of carbon materials in nuclear systems is discussed in Chapters 12 and 13, where fusion device and fission reactor applications, respectively, are reviewed. In Chapter 12 the major technological issues for the utilization of carbon as a plasma facing material are discussed in the context of current and future fusion tokamak devices.The essential design features of graphite moderated reactors, (including gas-, water- and molten salt-cooled systems) are reviewed in Chapter 13, and reactor environmental effects such as radiation damage and radiolytic corrosion are discussed. The fracture behaviour of graphite is discussed in qualitative and quantitative terms in Chapter 14. The applications of Linear Elastic Fracture Mechanics and Elastic-Plastic Fracture Mechanics to graphite are reviewed and a study of the role of small flaws in nuclear graphites is reported.
