Since the first date of publication of this book in 1991, the subject of phosphors and luminescence has assumed even more importance in the overall scheme of technological development. Many new types of displays have appeared which depend upon phosphors in their operation. Some of these were pure conjecture in 1991 but are a reality in 2004. Descriptions have been included of the newer (as well as the older) types of displays in this edition along with an annotated portrait of the phosphors used in each category. Many of these new light sources promise to displace and make obsolete our current light sources, such as incandescent lamps, fluorescent lamps and the ubiquitous colour Cathode Ray ...
Over two decades have passed since the fifth edition of Phosphorus: Chemistry, Biochemistry and Technology. Major advances in chemistry, materials science, electronics, and medicine have expanded and clarified the role of phosphorus in both our everyday appliances and groundbreaking research. Significantly expanded, updated, and reorganized, this sixth edition organizes and explains vital phosphorus research and relevant information available in highly specialized reviews and references on select related topics. An authoritative and comprehensive review of phosphorus chemistry and related technology, Phosphorus: Chemistry, Biochemistry and Technology covers historical, academic, industrial, ...
Contemporary Aspects of Boron: Chemistry and Biological Applications highlights the biological activity and applications of boron containing compounds. The authors' specific approach surveys general features of the subject, while exploring new and novel strategies for preparing certain chemical and natural boron products that are of significant substance in medicinal chemistry. For example, cancer treatment is one of the most important issues related to such products. In addition to contributing to the development of new drugs by addressing biological applications in medicinal and industrial fields, the book provides a comprehensive review of the most relevant components that comprise the pharmaceutical, medicinal and environmental applications of boron containing compounds.* Timely and comprehensive * Provides new insights to active researchers in the field * Presents concepts and methods in simple scientific terms
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 liquefact...
In this reference, the author thoroughly reviews the current state of condensed phosphate chemistry. A unique feature of this volume is an examination of the recent developments in X-ray structural techniques, reporting on fundamental results obtained through their use. Enhanced by comprehensive tables reporting crystal data, chapters identify and characterize more than 2,000 compounds. Additional features include a concise survey of the historical development of condensed phosphate chemistry; the presently accepted classification system; a review of each family of condensed phosphates and much more.
The author describes a novel method of preparing hydrolysis-stable non-silicate glasses which is based on experimental work accomplished over the past twenty years. As such, the method is the beginning of a new approach to glass-making by the use of a molecularly-polymerizable precursor. The book elucidates the technical details required to produce such molecularly-polymerized glasses from carefully prepared inorganic molecular monomers. Essentially, only silicate-based glasses have been known to be stable, whereas non-silicate glasses could not be attributed with such properties. Such glasses have, therefore, not found widespread usage in industry. The new phosphate glasses described here e...
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 paramagnet...
