A giant in the field and at times a polarizing figure, F. Albert Cotton's contributions to inorganic chemistry and the area of transitions metals are substantial and undeniable. In his own words, My Life in the Golden Age of Chemistry: More Fun than Fun describes the late chemist's early life and college years in Philadelphia, his graduate training and research contributions at Harvard with Geoffrey Wilkinson, and his academic career from becoming the youngest ever full professor at MIT (aged 31) to his extensive time at Texas A&M. Professor Cotton's autobiography offers his unique perspective on the advances he and his contemporaries achieved through one of the most prolific times in modern inorganic chemistry, in research on the then-emerging field of organometallic chemistry, metallocenes, multiple bonding between transition metal atoms, NMR and ESR spectroscopy, hapticity, and more. Working during a time of generous government funding of science and strong sponsorship for good research, Professor Cotton's experience and observations provide insight into this prolific and exciting period of chemistry. - Offers personal and often wry perspective from this prominent chemist and recipient of some of science's highest honors: the U.S. National Medal of Science (1982), the Priestley Medal (the American Chemical Society's highest recognition, 1998), membership in the U. S. National Academy of Sciences and corresponding international bodies, and 29 honorary doctorates - Details the background behind the development and emergence of groundbreaking research in organometallic chemistry and transition metals - Provides beautifully-written and engaging insight into a "Golden Age of Chemistry" and the work of historically renowned chemists
Superlubricity is defined as a sliding regime in which friction or resistance to sliding vanishes. It has been shown that energy can be conserved by further reducing/removing friction in moving mechanical systems and this book includes contributions from world-renowned scientists who address some of the most fundamental research issues in overcoming friction. Superlubricity reviews the latest methods and materials in this area of research that are aimed at removing friction in nano-to-micro scale machines and large scale engineering components. Insight is also given into the atomic-scale origins of friction in general and superlubricity while other chapters focus on experimental and practical aspects or impacts of superlubricity that will be very useful for broader industrial community.* Reviews the latest fundamental research in superlubricity today* Presents 'state-of-the-art' methods, materials, and experimental techniques* Latest developments in tribomaterials, coatings, and lubricants providing superlubricity
Cluster chemistry is one of the recent, exciting areas of Inorganic Chemistry. The occurence of molecular clusters, like fullerene C60, constitutes a fundamental feature midway between the chemistry of isolated chemical compounds and that of the elements. Main features of the Cluster Chemistry of both main group and transition metal elements are treated in this book. The author highlights aspects releated to the synthesis, the structure, the special bonding and the reactivity of these species. The book is written as a textbook for senior undergraduate and postgraduate students. References in tables andillustrations permit the reader to reach relevant original information. Professor Gonzalez-Moraga fills a demand for a publication appropriate for dissemination and specially for teaching this exciting subject. From the Contents: Current Concepts in Modern Chemistry - Transition Metal Cluster Chemistry - Main Group-Transition Metal Mixed Clusters - Cluster Compounds of the Main Group Elements - Synthetic Analogues of the Active Sites of Iron-Sulfur Proteins.
Iron–sulfur (FeS) centers are essential protein cofactors in all forms of life. They are involved in many key biological processes. In particular, Fe-S centers not only serve as enzyme cofactors in catalysis and electron transfer, they are also indispensable for the biosynthesis of complex metal-containing cofactors. Among these cofactors are the molybdenum (Moco) and tungsten (Wco) cofactors. Both Moco/Wco biosynthesis and Fe-S cluster assembly are highly conserved among all kingdoms of life. After formation, Fe-S clusters are transferred to carrier proteins, which insert them into recipient apo-proteins. Moco/Wco cofactors are composed of a tricyclic pterin compound, with the metal coordinated to its unique dithiolene group. Moco/Wco biosynthesis starts with an Fe-S cluster-dependent step involving radical/S-adenosylmethionine (SAM) chemistry. The current lack of knowledge of the connection of the assembly/biosynthesis of complex metal-containing cofactors is due to the sheer complexity of their synthesis with regard to both the (genetic) regulation and (chemical) metal center assembly. Studies on these metal-cofactors/cofactor-containing enzymes are important for understanding fundamental cellular processes. They will also provide a comprehensive view of the complex biosynthesis and the catalytic mechanism of metalloenzymes that underlie metal-related human diseases.
