A frequently misunderstood technology, die casting is considered the shortest route between raw material and near net shape. For many decades, high pressure die casting was viewed as an art based upon "seat of the pant" strategies. However, many of these crude reactions actually worked because the fundamental process is quite forgiving of eccentricities. Exploring these reactions with scientific logic, Die Casting Engineering presents a broad study of each procedure in the die casting process and clearly outlines its basic science and principles. This guide is written in a reader-friendly and logical format by an experienced authority in quality and productivity enhancement, tooling design, metal feed system analysis, temperature management, and environmental regulation. While its scope is broad and covers the many facets of die casting, the book's main focus is on function, problem identification and solution, and strategic logic. Generously illustrated, it provides a comprehensive explanation of why high pressure die casting is reliable, predictable, and teachable.

Design of new processes that avoid the use of toxic reagents has been the focus of intense research of late. Catalysis by metals and non-metals offers diverse opportunities for the development of new organic reactions with promising range of selectivities-chemoselectivity, regioselectivity, diastereoselectivity, and enantioselectivity. Furthermore, these transformations frequently occur under mild conditions, tolerate a broad array of functional groups, and proceed with high stereoselectivity. The area of catalysis is sometimes referred to as a 'foundational pillar' of green chemistry. Catalytic reactions often reduce energy requirements and decrease separations because of increased selectivity; they are also capable of permitting the use of renewable feedstocks of less toxic reagents or minimizing the quantities of reagents needed. New catalytic organic synthesis methodologies have, thus, offered several possibilities for considerable improvement in the eco-compatibility of fine chemical production. Hence, these catalytic methodologies have emerged as powerful tools for the efficient and chemoselective synthesis of heterocyclic molecules. Key Features: Presents the synthesis of different five-membered heterocycles. Contains the most up-to-date information in this fast-moving field. Covers novel catalytic approaches used in the study and application of catalysts in synthetic organic reactions. Presents new methodologies for the synthesis of heterocycles.

It outlines the typical features of the soft liquid-metal materials and describes the various transformation capabilities, mergence of separate metal droplets, self-rotation and planar locomotion of liquid-metal objects under external or internal mechanism. Further, it introduces a series of unusual phenomena discovered while developing the shape changeable smart soft machine and interprets the related mechanisms regarding the effects of the shape, size, voltage, orientation and geometries of the external fields to control the liquid-metal transformers. Moreover, the book illustrates typical strategies to construct a group of different advanced functional liquid-metal soft machines, since such machines or robots are hard to fabricate using rigid-metal or conventional materials. With highly significant fundamental and practical findings, this book is intended for researchers interested in establishing a general method for making future smart soft machine and accompanying robots.

Adsorption and desorption in solution play significant roles in separations, detoxification of waste streams, in purification, chromatography, heterogeneous catalysis, metabolism of medicinal drugs, and beyond. Metal-Organic Frameworks (MOFs) are well-ordered 3-dimensional hybrid organic-inorganic polymers which contain metal cations and the structure-building organic "linker" units. Mesoporous MOFs with pore sizes 2-50 nm are particularly suitable for adsorption and adsorption-based separations of large molecules of organic and bio-organic compounds. Thousands of organic compounds and, in particular, aromatic and heterocyclic compounds are widely used as feedstock for industrial chemical synthesis, as fine chemicals, major components of liquid fossil fuels, dyestuffs, industrial solvents, agricultural chemicals, medicinal drugs, pharmaceuticals and personal care products (PPCPs), and active pharmaceutical ingredients (APIs). There is a strong interest towards synthesis, characterization and studies of both known and newly synthesized mesoporous MOFs for adsorption in solution to achieve the high adsorption capacity, selectivity, and the possibility of multiple regeneration of "spent" sorbent. This book covers experimental fundamental research on using mesoporous MOFs in emerging applications of major industrial, environmental and academic importance, especially purification of water and liquid fossil fuels and in advanced biomedical technologies.

Hydrometallurgy is a field of chemical technology concerned with the production of metals from their ores and secondary sources. Modern hydrometallurgy began with the need to obtain uranium in the 1940s and extended into new areas with the development of pressure hydrometallurgy in the mid-1950s and acceptance of solvent extraction as an industrial scale process for copper production in the late 1960s to early 1970s. With the introduction of new processes for many metals, the present stage of development of hydrometallurgy has come to maturity and a survey of the current state of the field is timely.This book is derived from the lectures on the principles on which hydrometallurgical processes are based, given as part of the undergraudate and MSc courses in hydrometallurgy which Professor A R Burkin gave from 1961 until he retired in 1988.Professor Burkin's earlier book, The Chemistry of Hydrometallurgical Processes, was regarded as the major work in the field. This is his long awaited new textbook.
