Metallo-Supramolecular Polymers: Synthesis, Properties, and Device Applications (NIMS Monographs)

by Masayoshi Higuchi

This book introduces the synthesis, electrochemical and photochemical properties, and device applications of metallo-supramolecular polymers, new kinds of polymers synthesized by the complexation of metal ions and organic ditopic ligands. Their electrochemical and photochemical properties are also interesting and much different from conventional organic polymers. The properties come from the electronic intra-chain interaction between the metal ions and the ligands in the polymer chain. In this book, for example, the electrochromism that the Fe(II)-based metallo-supramolecular polymer exhibits is described: the blue color of the polymer film disappears by the electrochemical oxidation of Fe(II) ions to Fe(III) and the colorless film becomes blue again by the electrochemical reduction of Fe(III) to Fe(II). The electrochromism is explained by the disappearance/appearance of the metal-to-ligand charge transfer absorption. The electrochromic properties are applicable to display devices such as electronic paper and smart windows.

Metallocenes in Regio- and Stereoselective Synthesis (Topics in Organometallic Chemistry #74)

by Marko Hapke Martin Kotora

This book presents the latest synthetic protocols for the assembly of functionalized Cp ligands and their transition metal complexes. Cyclopentadienyl (Cp) complexes of transition metals belong to the most important classes of transition metal complexes with tightly bound ligands in the coordination sphere since their discovery in the middle of the last century. Even though they have been known for a long time, this field constantly evolves to deliver novel modified Cp ligands and complexes and to blossom into new fields of application. Beside the synthesis of ligands and metal complexes this book concentrates on novel and prospering fields of their application in organic synthesis. In this respect the Cp complexes have been applied to induce and catalyze various significant chemical transformations such as new C-C bond formation involving unsaturated substrates (e.g. cyclotrimerizations, cycloadditions, carbometallations, etc.), C-H bond and C-C bond activations followed by subsequent reactions (e.g. arylation, alkenylations, annulations, etc.), as well as many other processes. This volume also covers the recent development and application of chiral Cp complexes in enantioselective synthesis.

Metallocofactors that Activate Small Molecules: With Focus on Bioinorganic Chemistry (Structure and Bonding #179)

by Markus W. Ribbe

This volume highlights recent progress on the fundamental chemistry and mechanistic understanding of metallocofactors, with an emphasis on the major development in these areas from the perspective of bioinorganic chemistry. Metallocofactors are essential for all forms of life and include a variety of metals, such as iron, molybdenum, vanadium, and nickel. Structurally fascinating metallocofactors featuring these metals are present in many bacteria and mediate remarkable metabolic redox chemistry with small molecule substrates, including N2, CO, H2, and CO2. Current interest in understanding how these metallocofactors function at the atomic level is enormous, especially in the context of sustainably feeding and fueling our planet; if we can understand how these cofactors work, then there is the possibility to design synthetic catalysts that function similarly.

Metallocorroles for Attenuation of Atherosclerosis

by Adi Haber

Adi Haber's thesis summarises the use of a new entity, the corrole, to combat one of the major cardiovascular diseases, atherosclerosis. She examines the effects of three rationally designed corrole-metal complexes on some of the many variables which contribute to the development of atherosclerosis. There is a focus on both the "bad" and "good" cholesterol carriers, LDL and HDL. Adi Haber proceeds from basic findings in pure chemistry through biochemical and cell culture tests to in vivo examinations. The work in this thesis shows that corroles are highly efficient both for early and late treatment of atherosclerosis in animals. These results will pave the way for ongoing regulated preclinical studies focussed on the development of metallocorroles as potential drugs for treating cardiovascular diseases.

Metallofoldamers

by Galia Maayan Markus Albrecht

Metallofoldamers are oligomers that fold into three-dimensional structures in a controlled manner upon coordination with metal ions. Molecules in this class have shown an impressive ability to form single-handed helical structures and other three-dimensional architectures. Several metallofoldamers have been applied as sensors due to their selective folding when binding to a specific metal ion, while others show promise for applications as responsive materials on the basis of their ability to fold and unfold upon changes in the oxidation state of the coordinated metal ion, and as novel catalysts.Metallofoldamers: From Helicates to Biomimetic Architectures describes the variety of interactions between oligomers and metal species, with a focus on non-natural synthetic molecules.Topics covered include:the major classes of foldamers and their folding driving forcemetalloproteins and metalloenzymeshelicates: self-assembly, structure and applicationsabiotic metallo-DNAmetallo-PNA and iDNAmetallopeptidesinteractions of biomimetic oligomers with metal ionsapplications of metallofoldamers

Metallography in Archaeology and Art (Cultural Heritage Science)

by David A. Scott Roland Schwab

This book provides a comprehensive introduction to the metallographic study of ancient metals. Metallography is important both conceptually as a microstructural science and in terms of its application to the study of ancient and historic metals. Metallography is a well-established methodology for the characterization of the microstructure of metals, which continues to be significant today in quality control and characterization of metallic properties. Not only does the metallographic examination of ancient metals present its own challenges in terms of sample size and interpretation of evidence, but it must be integrated with archaeological data and cultural research in order to obtain the most meaningful results. Issues of authentication and the establishment of fakes and forgeries of metallic artefacts often involve metallographic evidence of both metal and patina or corrosion interface, as an essential component of such a study. The present volume sets out the basic features of relevant metallic systems, enhanced with a series of examples of typical microstructural types, with illustrative case studies and examples throughout the text derived from studies undertaken by the two authors. This book provides a comprehensive presentation of metallography for archaeologists, archaeometallurgists, conservators, conservation scientists and metallurgists of modern materials.

Metalloids in Biology: From Function to Toxicity

by Renu Bhardwaj Geetika Sirhindi Nitika Kapoor Chandra Shekhar Seth

Metalloids belong to class of elements that exhibit physiochemical characteristics intermediating between those of metals and non-metals. Some are quasi-essential for the overall growth and development of plants. Silicon, for instance, enhances plant structural integrity, while boron is crucial for cell wall formation, and selenium acts as an antioxidant but some are toxic, like germanium (Ge) and arsenic (As), as they threaten the soil ecosystem and human health. Metalloid toxicity hinges on their cellular concentrations ,where low levels aid plant development ,whereas high levels cause harmful effects. Thus, it is crucial to encompass the underlying detoxification mechanisms behind metalloid uptake by root system, their transport to other tissues, and their redistribution within and between cells. This book provides a comprehensive elucidation of the valuable insights of metalloids in green agriculture emphasizing management strategies to mitigate their adverse effects through various detoxification pathways, including cell complexation, cell wall binding, efflux, vacuolar sequestration and ultimately redistribution. Key features:1.Explores databases of metalloid distribution in plants and other habitats. 2.Deliberates about metalloid transporters and detoxification strategies in plants. 3. Describes interaction of metalloids with microbes and their impact on ecophysiology. 4. Unravels the mysteries of metalloid stress in plants by using multi-omics approaches. 5. Covers biological applications of metalloids in sustainable agricultural practices and in human health.This book is aimed to give updated and scientific insights to readers and researchers associated with plant stress physiology, agricultural sciences and environmentalists working for the well-being of the environment. Apart from these, the present book will also be boon for scientists, farmers, teachers and undergraduate and post graduate students as it provides a detailed account of distribution, biochemistry, detoxification mechanisms, and biological applications of metalloids.

Metalloprotein Active Site Assembly

by Robert A. Scott Michael K. Johnson

Summarizes the essential biosynthetic pathways for assembly of metal cofactor sites in functional metalloproteins Metalloprotein Active Site Assembly focuses on the processes that have evolved to orchestrate the assembly of metal cofactor sites in functional metalloproteins. It goes beyond the simple incorporation of single metal ions in a protein framework, and includes metal cluster assembly, metal-cofactor biosynthesis and insertion, and metal-based post-translational modifications of the protein environments that are necessary for function. Several examples of each of these areas have now been identified and studied; the current volume provides the current state-of-the-art understanding of the processes involved. An excellent companion to the earlier book in this series Metals in Cells—which discussed both the positive and negative effects of cellular interactions with metals—this comprehensive book provides a diverse sampling of what is known about metalloprotein active site assembly processes. It covers all major biological transition metal components (Mn, Fe, Co, Ni, Mo), as well as the other inorganic components, metal-binding organic cofactors (e.g., heme, siroheme, cobalamin, molybdopterin), and post-translationally modified metal binding sites that make up the patchwork of evolved biological catalytic sites. The book compares and contrasts the biosynthetic assembly of active sites involving all biological metals. This has never been done before since it is a relatively new, fast-developing area of research. Metalloprotein Active Site Assembly is an ideal text for practitioners of inorganic biochemistry who are studying the biosynthetic pathways and gene clusters involved in active site assembly, and for inorganic chemists who want to apply the concepts learned to potential synthetic pathways to active site mimics.
