  • Molybdenum

    An Outline of its Chemistry and Uses
    • 1st Edition
    • Volume 19

    • English
    Molybdenum is an element with an extremely rich and interesting chemistry having very versatile applications in various fields of human activity. It is used extensively in metallurgical applications. Because of their anti-wear properties, molybdenum compounds find wide applications as lubricants - particularly in extreme or hostile environmental situations. Many molybdates and heteropolymolybdates are white and therefore used as pigments. In addition, they are non-toxic and act as efficient corrosion inhibitors and smoke suppressants. Hydroprocessing of petroleum is one of the largest industries employing heterogeneous catalysts. Molybdenum catalysts have shown great promise in the liquefaction of coal and this may develop into one of its most important catalytic uses. The use of molybdenum compounds in homogeneous catalysis is also significant.Three important classes of molybdenum compounds in the solid state are reviewed, viz., oxides, sulphides and halides. The role of molybdenum in inorganic catalysis and enzymes receives prominent mention because of their impact on the progress of science and technology. Further biochemical and enzymic factors are discussed in separate chapters and their reaction to agriculture and animal husbandry.A new classification of covalent compounds which abandons the traditional oxidation state concept allows a powerful approach to the organisation of the complex and rich chemistry of molybdenum. Dramatic colour diagrams of abundances of molybdenum compounds provide broad insights into the important features and trends in the chemistry of molybdenum including reactivity and mechanism.The book is intended for use mainly as a research monograph by the many workers who may encounter molybdenum chemistry or who are looking for its application and potential uses in different technological fields. However, it will also serve as an advanced text for university lecturers and postgraduate students interested in inorganic, physical and industrial chemistry, chemical technology or biochemistry and biotechnology.

  • Weathering, Soils & Paleosols

    • 1st Edition
    • Volume 2
    • I.P. Martini + 1 more
    • English
    For the past 200 years, geological scientists have used the present as a key to unlocking the past. This volume continues the tradition by exploring the processes of weathering and soil formation as indicators of the present environment of the Earth's land surface. Examined are the various ways in which this information can be used to interpret past environments which have produced the soils now preserved as paleosols. Because the surface environment of the earth may now be undergoing rapid change (the greenhouse effect), the book is a timely one for those researchers looking for evidence of analogous changes in the Earth's past. The work is divided into three major sections. The first deals with fundamental considerations of weathering, clay mineralogy and diagenesis. The second deals with the formation of soils from various starting materials and in various surficial environments. And the final section is an interpretation of paleosols. This volume provides valuable reading material for graduate and senior-undergraduate courses.

  • Electron Paramagnetic Resonance of d Transition Metal Compounds

    • 1st Edition
    • Volume 16
    • F.E. Mabbs + 1 more
    • English
    Electron paramagnetic resonance (epr) spectroscopy is a sensitive and versatile method of studying paramagnets, which is finding increasing use in chemistry, biochemistry, earth and materials sciences. The technique is treated both qualitatively and quantitatively, with a progressive increase in sophistication in each succeeding chapter. Following a general introductory chapter, the first half of the book deals with single unpaired electron systems and considers both metal and ligand Zeeman, hyperfine and quadrupole interactions. The simulation of these spectra is discussed, followed by the relationship between spin-Hamiltonian parameters and models of the electronic structures of paramagnets. The second half of the book treats multiple unpaired electron systems using the same philosophy. An introduction to the epr properties of cluster compounds and of extended exchanging systems is also given. There is a chapter on linewidths and lineshapes, and an extensive appendix containing much additional information. A wide-ranging library of simulated and experimental spectra is given, as well as graphical data which should aid spectrum interpretation. Each chapter contains key references and there is a substantial subject and keyword index. This book is designed to teach epr spectroscopy to students without any previous knowledge of the technique. However, it will also be extremely useful to researchers dealing with paramagnetic d transition metals.

  • Organic Chemistry in Action

    The Design of Organic Synthesis
    • 1st Edition
    • Volume 41
    • F. Serratosa
    • English
    Contrary to all other books in the field of organic synthesis, this volume combines Corey's methodology, which is based on the concept of synthon and retrosynthetic analysis, with Evans' methodology based on the `Lapworth model' of alternating polarities. Using this approach, the formation of carbon-carbon bonds and the manipulation of functional groups are treated together, whereas the stereochemical aspects are considered separately. Emphasis is laid on the importance of rigid structures, whether in the starting materials, the synthetic intermediates or the transition states, as a means of controlling the stereochemistry of the organic compounds.Enclosed with the book is a copy of a miniprogram (CHAOS) for an IBM PC, or fully compatible computers, which is an interactive program, affording the beginner a fast and easy way of learning, exploring and looking for new synthetic schemes of molecules of moderate complexity. As a textbook on organic synthesis, this volume will be of immense value at university level.

  • Advanced Theories of Hypoid Gears

    • 1st Edition
    • Volume 36
    • Xudong Wang + 1 more
    • English
    In order to develop more efficient types of gears, further investigation into the theories of engagement is necessary. Up until now most of the research work on the theories of engagement has been carried out separately on different groups, and based on individual types of profiles. This book aims at developing some universal theories, which can not only be used for all types of gears, but can also be utilized in other fields such as sculptured surfaces. The book has four characteristics: the investigations are concentrated on mismatched tooth surfaces; all the problems are dealt with from a differential geometry point of view; most theories and algorithms are universal in application; and the algorithms are easy to follow and can be used in real situations. In the process of developing the algorithms, the authors have introduced some mathematical methods which are believed to be innovative with regard to the theories of engagement known so far. A theoretical treatment is presented throughout the book, supported by numerical examples and experiments. With the computer programs listed at the end of the volume, any of the proposed methods can be easily utilized in practice.The book is intended for postgraduate students, lecturers, professors, or research staff in mechanical/manufactu... engineering, mathematics and R & D departments of research institutes and universities. It will also be useful for engineers working in the gear manufacturing sector of industry.

Organized into four parts encompassing 45 chapters, this volume begins with an overview of the gravimetric research carried out in various locations in Maracaibo Basin Area. This text then evaluates the reliability of the leveling measurements using modified geodetic checks as well as through comparison with independent measurements of crustal movement. Other chapters consider the basis of geodetic strain analysis. This book discusses as well the first-order geodetic measurements in seismically active areas in southern and southwestern Australia. The final chapter deals with the correlation of the data of relevelling with surface relief. This book is a valuable resource for engineers and geologists.
