The present volume finalizes the coverage of organocopper compounds. A complete formula and ligand index for the Gmelin organocopper series will appear shortly as" Organa copper Compounds" 5. The volume describes mononuclear compounds with ligands bonded by two or more carbon atoms as well as all di- to octanuclear and polymeric compounds. Mononuclear compounds with ligands bonded by one carbon atom have already been described in Vol umes 1 (published in 1985), 2 (published in 1983), and 3 (published in 1986). As structural elucidation in organocopper chemistry gained more attention only in the last few years, the terms "mononuclear", "dinuclear" etc. have been used as explained in "Organocopper Compounds" 1, 1985, pp. 3/4: all compounds are treated with their small est formula unit unless a higher nuclearity has been proved. As a consequence, most of the species treated in volumes 1 to 3 are described there because of insufficient structural information although they are alleged not to be monomeric. This way, many of the better characterized compounds appear in the present volume which is reflected by the more than eighty X-ray structure figures. Generally, nuclearity and structure are not only deter mined by the coordination properties of the ligands, but also by steric requirements, and may therefore widely differ for analogous compounds.

The electrocatalytic reduction of CO2 into high-value multi-carbon products represents a crucial pathway toward achieving carbon neutrality and sustainable chemical production. The transition from lab-scale studies to industrial-scale implementation is imperative to bridge the gap between fundamental mechanistic insights and practical applications. This book explores the mechanistic understanding and functional design of electrocatalysts for CO2 electroreduction, focusing on bridging the gap between lab-scale research and industrial-scale implementation. It systematically investigates the role of grain boundary structures, oxidation states, and interfacial microenvironments in stabilizing Cu-based catalysts, thereby enhancing the selective production of multi-carbon products. By integrating oxidation and alloying strategies, this work introduces new approaches to modulate copper oxidation states, leading to improved catalytic performance. Advanced characterization techniques, including in situ multimodal spectroscopy, provide insights into the electrochemical stability of Cuδ+ species and their impact on reaction pathways. Beyond catalyst design, this book extends the discussion to CO2 electrolyzer configurations, emphasizing membrane electrode assemblies and gas diffusion electrode engineering for scalable applications. The introduction of functionalized carbon black to modulate the interfacial environment, effectively suppresses the hydrogen evolution reaction, stabilizing active Cuδ+ species and promoting ethylene production with high Faradaic efficiency. By integrating fundamental insights with industrial feasibility, this book offers a comprehensive guide for researchers and engineers developing next-generation CO2 electrolysis technologies, contributing to carbon-neutral chemical manufacturing and sustainable energy solutions.

A Review of the Alumina/Ag-Cu-Ti Active Metal Brazing Process is based on the PhD thesis entitled "The Effects of Alumina Purity, Ticusil® Braze Preform Thickness and Post-grinding Heat Treatment, on the Microstructure, Mechanical and Nanomechanical Properties of Alumina-to-Alumina Brazed Joints" which was awarded by Imperial College London’s CASC Steering Group as the 2017 recipient of the Professor Sir Richard Brook Prize (sponsored by Morgan Advanced Materials plc) for Best Ceramics PhD Thesis in the UK. It focusses on the alumina/Ag-Cu-Ti system to cover the active metal brazing of ceramics, variables involved in the process, and the effects of these variables on wetting, interfacial reaction layer formation, and joint strength. The comprehensive review brings together findings from the literature into one place, and presents key concepts in a concise and easy- to-read manner.

High c oxide superconductors such as Bi(Pb)-Sr-Ca-Cu-O (BSCCO) and Y-Ba-Cu-O (YBCO) systems are usually fabricated by sintering given mixtures of raw materials. Generally, sintering processing takes a longer heating time and the products are mechanically low strength and cannot be formed into complex shapes such as a coil, a curved fine tube or a fine rod. Another way to produce the ceramics is a glass-ceramic process in which the glasses prepared by melt-quenching are reheated for crystallization. A given mixture of raw materials in BSCCO is easily melted and quenched to form a given shape of glass, while that in YBCO is not glassified.This invaluable book has been written by authors from five countries. It presents a unique way to fabricate superconducting ceramics in BSCCO by glass-ceramic processing.

Cu(In1-xGax)Se2 Based Thin Film Solar Cells provides valuable contents about the fabrication and characterization of chalcopyrite Cu(In1-xGax)Se2 based thin film solar cells and modules. The growth of chalcopyrite Cu(In1-xGax)(S1-ySey)2 absorbers, buffers, window layers, antireflection coatings, and finally metallic grids, which are the sole components of solar cells, is clearly illustrated. The absorber, which contains multiple elements, segregates secondary phases if the growth conditions are not well optimized i.e., the main drawback in the fabrication of solar cells. More importantly the solutions for the growth of thin films are given in detail. The properties of all the individual layers and single crystals including solar cells analyzed by different characterization techniques such as SEM, AFM, XPS, AES, TEM, XRD, optical, photoluminescence, and Raman spectroscopy are explicitly demonstrated. The electrical analyses such as conductivities, Hall mobilities, deep level transient spectroscopy measurements etc., provide a broad picture to understand thin films or single crystals and their solar cells. The book clearly explains the working principle of energy conversion from solar to electrical with basic sciences for the chalcopyrite based thin film solar cells. Also, it demonstrates important criteria on how to enhance efficiency of the solar cells and modules. The effect of environmental factors such as temperature, humidity, aging etc., on the devices is mentioned by citing several examples. - Illustrates a number of growth techniques to prepare thin film layers for solar cells - Discusses characterization techniques such as XRD, TEM, XPS, AFM, SEM, PL, CL, Optical measurements, and Electrical measurements - Includes I-V, C-V measurements illustrations - Provides analysis of solar cell efficiency - Presents current trends in thin film solar cells research and marketing

Nanostructured materials are materials with grain size smaller than 100 nm. Due to the very small grain size, a large fraction of atoms belong to the grain-boundaries. As a result, their properties are significantly different compared to their coarse-grained counterparts. Generally, a considerable improvement in the properties is observed when the size is reduced to nanometer dimensions. These include high strength and hardness, improved ductility and toughness, as well as enhanced diffusivity, which make this category of materials of particular interest for a wide range of applications. The properties of nanocrystalline materials are strongly affected by their structure and defects density, which in turn are determined by the method of production. As a result, the knowledge of the mechanism of nanostructure formation is a prerequisite for the structure/property optimization.

Coordination chemistry and metal complexes is one of the active fields of research in Chemistry. The scope of this field has now become so broad that the number and the kind of compounds with which it is concerned is large enough for the metal compounds and complexes to gain importance in clinical, pharmacological, medicinal, analytical and industrial areas. Schiff bases are most widely used as chelating agents in coordination chemistry. The synthesis and application of Schiff base and their coordination compounds have been highly considered in inorganic and bioinorganic fields as their structural properties are similar to those of the compounds involved in biological systems. The transition metal complexes of Schiff bases derived from heterocyclic compounds have been the centre of attraction for many workers in recent years.
