Cerium Oxide (CeO2): Synthesis, Properties and Applications provides an updated and comprehensive account of the research in the field of cerium oxide based materials. The book is divided into three main blocks that deal with its properties, synthesis and applications. Special attention is devoted to the growing number of applications of ceria based materials, including their usage in industrial and environmental catalysis and photocatalysis, energy production and storage, sensors, cosmetics, radioprotection, glass technology, pigments, stainless steel and toxicology. A brief historical introduction gives users background, and a final chapter addresses future perspectives and outlooks to stimulate future research. The book is intended for a wide audience, including students, academics and industrial researchers working in materials science, chemistry and physics. Addresses a wide range of applications of ceria-based materials, including catalysis, energy production and storage, sensors, cosmetics and toxicology Provides the fundamentals of ceria-based materials, including synthesis methods, materials properties, toxicology and surface chemistry Includes nanostructured ceria-based materials and a discussion of future prospects and outlooks
An approach to the investigation of the thermodynamic and kinetic stability of variable-valence metal complexes has been developed. Concepts of the generalised inverse problems of quantitative instrumental analysis and the complex formation equilibria are introduced. The procedure for this investigation is regarded as a sequential procedure for solving these two inverse problems. The classical methods for investigating the complex formations in solution are analysed in terms of these in-verse problems. Their generalisations are given to determine together with the formation constants also redox-decomposition rate constants of variable-valence metal complexes and the rate law of numerous redox processes, for which the rate-determining step is the decay of an intermediate complex, are presented. Classification is discussed and their implementation on the examples of the study of the complexation and in-tramolecular redox decomposition of cerium(IV) hydroxo complexes with some dicarboxylic, oxycarboxylic acids and aliphatic polyatomic alcohols in dependence on acidity (pH 0.73.4) of a sulphate medium at the ionic strength I=2 and temperatures of 10.043.0℃C by UV-Vis spectroscopy and pH measurements. The region of existence, composition, ligand speciation, stability constants of the complexes [CeOH(H-xR)n]3-nx, rate constants, and activation energies of the intramolecular redox decomposition were determined for these complexes on the sulphate background. The rate law of the redox process occurring in the studied systems on the basis of the calculated constants and set of all the chemical and algebraic equations describing the equilibria in systems is derived, and the quantitative model of this process is created. The existence of positive correlation between thermodynamic and kinetic stability of the complexes [CeOHH-xR]3-x with x > 2 and its absence for x > 2 was found on the sulphate background. Discussed also are the computational aspects of solving the regarded generalised problems. This book is well-suited for researchers in the chemistry of co-ordination compounds, physical chemistry, and biochemistry, as well as faculty and advanced students.
The redox chemistry of rare earth elements has broad applications in synthetic chemistry, material chemistry, and separations. However, in terms of the +3/+4 redox chemistry of molecular lanthanide compounds, only the CeIII/IV redox properties have been extensively studied because the other molecular lanthanide (IV) complexes have not yet been isolated and characterized. In this dissertation, progress toward the isolation of lanthanide (IV) guanidinate complexes is demonstrated. The stabilization of cerium (IV) oxidation state by guanidinate ligand framework is investigated. Investigations of oxidation reactions of other lanthanide (III) guanidinate complexes are reported.
Alkoxo and Aryloxo Derivatives of Metals gives a comprehensive account of the chemistry of metal alkoxides and metal aryloxides, including their industrial applications such as microelectronics, ceramics, nonlinear optical materials, high-temperature superconductors, specialized glasses, and other advanced novel materials. It is an invaluable reference source book. The book is an updated edition of Metal Alkoxides, published by Academic Press in 1978, with additional coverage of metal aryloxides. It reflects the enormous growth in interest in this field in recent years. Alkoxo and aryloxo derivatives are organic compounds with metals for useful industrial purposes. Alkoxo and Aryloxo Derivatives of Metals will appeal to a wide-ranging audience, including university researchers and chemistry graduate students in industrial laboratories concerned with microelectronics, ceramics, glasses and other advanced novel materials; any laboratories doing research on nonlinear optical materials, high-temperature superconductors, ceramic materials, and specialized glasses. It can also serve as a supplementary text for final year courses in advanced inorganic chemistry, e.g., metallo-organic chemistry.

The systematic introduction of basic knowledge, application technology and the latest developments in the field, makes this ideal for readers across both introductory and specialist levels.
This book is devoted to general questions of the chemistry of metal alkoxides – including physiochemical properties, structure, specific features of single groups of alkoxides, theoretical principles of their use, and major applications of this method in the preparation of functional materials.
This book provides an overview of the origins and evolution of the periodic system from its prehistory to the latest synthetic elements and possible future additions. The periodic system of the elements first emerged as a comprehensive classificatory and predictive tool for chemistry during the 1860s. Its subsequent embodiment in various versions has made it one of the most recognizable icons of science. Based primarily on a symposium titled “150 Years of the Periodic Table” and held at the August 2019 national meeting of the American Chemical Society, this book describes the origins of the periodic law, developments that led to its acceptance, chemical families that the system struggled to accommodate, extension of the periodic system to include synthetic elements, and various cultural aspects of the system that were celebrated during the International Year of the Periodic Table.
