Available in PDF, EPUB and Kindle. Book excerpt: Discover the cutting-edge progress of a promising class of materials significant for use in energy technologies as catalysts Materials are said to be metastable-phases if they can retain their stability when subjected only to slight disturbances. Materials in metastable-phases can have very different properties from those in a state of equilibrium, and can perform very differently under conditions of experimentation, work, or industrial use. Metastable-phase materials are therefore a promising area of study in a variety of different fields, including cutting-edge industries. Metastable-Phase Materials constitute a wide-ranging overview of these materials, their properties, and their applications. Beginning with an overall characterization of metastable-phase materials and their normal modes of synthesis, it characterizes the most important branch of metastable-phase materials and reviews a range of catalytic applications. The result is a critical contribution to materials science and catalytic chemistry with potentially far-reaching implications. Metastable-Phase Materials readers will also find: Treatment of metastable-phase metal materials, 2D metastable-phase materials, and spin-dependent metastable-phase materials Detailed discussion of metastable-phase material applications in electrocatalysis, photocatalysis, thermalcatalysis, and more State-of-the-art technological applications in a myriad of areas Metastable-Phase Materials are ideal for materials scientists, catalytic chemists, inorganic chemists, photochemists, electrochemists, organic chemists, and the libraries that serve these communities.
Download or read book Metastable Phases and Microstructures Volume 400 written by Rüdiger Bormann and published by . This book was released on 1996-07-25 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Materials with metastable structures and microstructures have been used with success to create unusual structural and functional properties and property combinations. Highly nonequilibrium technologies for creating metastable materials have been devised which allow materials to be prepared far away from the thermodynamic equilibrium. Using these methods, materials can now be designed to possess specific properties tailored to fit an application, rather than fitting an application to the properties of available materials. However, as these materials are metastable with respect to structural and compositional changes under temperature, there is great concern for understanding and controlling their limitations. This book features both fundamental as well as applied aspects of the subject by stressing the structure/property relationships, the conditions for stability of these materials, and the requirements for technological applications. In addition to the synthesis, processing, characterization, properties, and applications of such materials, attention is also focused on the modelling of structures, phenomena and processes. Topics include: synthesis and processing; thermodynamic and kinetics; phase transformations and properties and applications.

Book excerpt: Rapidly Quenched Metals, Volume I covers the proceedings of the Fifth International Conference on Rapidly Quenched Metals, held in Wurzburg, Germany on September 3-7, 1984. The book focuses on amorphous and crystalline metals formed by rapid quenching from the melt. The selection first covers the scope and trends of developments in rapid solidification technology, rapid solidification, and undercooling of liquid metals by rapid quenching. Discussions focus on experimental method, powders, strip, particulate production, consolidation, and alloys and alloy systems. The text then examines the solidification of undercooled liquid alloys entrapped in solid; crystallization kinetics in undercooled droplets; and grain refinement in bulk undercooled alloys. The manuscript tackles the undercooling of niobium-germanium alloys in a 100 meter drop tube; influence of process parameters on the cooling rate of the meltspinning process; and the mechanism of ribbon formation in melt-spun copper and copper-zirconium. The formation and structure of thick sections of rapidly-solidified material by incremental deposition and production of ultrafine dispersions of rare earth oxides in Ti alloys using rapid solidification are also mentioned. The selection is a valuable reference for physicists, chemists, physical metallurgists, and engineers.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In nanochemistry, it is a common goal to be able to synthesize materials with a specific morphology, composition, size, and crystal structure. This type of synthetic control is desirable as even small changes in one of these four factors can lead to drastically different material properties. An example of this is the formation of non-equilibrium crystal phases which are metastable in bulk systems and often exhibit characteristics unique from the thermodynamically stable phase. Consequently, these metastable phases are favored for certain applications due to their properties. However, attempts to synthesize a phase pure sample of a non-equilibrium crystal phase are often fraught with difficulties as phase determining factors are not well understood for nanoscale syntheses. As a result, nanoscale synthetic research is frequently performed in an exploratory, semi-serendipitous method. It is therefore desirable to expand our understanding of nanoscale reactions so as to facilitate the directed synthesis of specific nanoscale targets. In the research reported herein, attempts were made to elucidate the phase determining factors in two systems: polyol synthesis of manganese(II) sulfide, and cation exchange with cobalt and manganese. First, a manganese(II) sulfide, MnS, polyol synthesis was studied to elucidate which reaction variables have the greatest impact in crystal phase determination. Initial research showed that reaction temperature, aging time, and manganese source had the greatest influence on the crystal phase of the MnS product. Further investigation of this reaction implied that a complex relationship exists between the decomposition rate of the sulfur source, the concentration of the tetramethylammonium hydroxide pentahydrate, and the presence of an in situ intermediate. Although this complex relationship was not deconvoluted through this research, these results nevertheless help to shed light on the phase determining factors in the polyol synthesis of manganese(II) sulfide. In addition, cation exchange was investigated as a method for the synthesis of metastable phases. Although the use of ion exchange to access metastable phases had been reported previously, much of this research was limited to copper, silver, cadmium, lead and zinc chalcogenides.1-3 In this work, cation exchange with cobalt and manganese from a roxbyite-type Cu2-xS precursor was explored. Ultimately, metastable wurtzite-type cobalt- and manganese sulfides were synthesized through this exchange process. This result is of great interest for several reasons. First of all, cation exchange was performed with two transition metal cations which had previously only served as dopants in exchange reactions. This work also demonstrates a colloidal method for the synthesis of wurtzite-type CoS which had previously only been synthesized through chemical bath deposition methods.4 Finally, formation of the metastable wurtzite-type phases demonstrates the retention of both anion and cation sublattice features -- a result which has not been reported in literature to date.

This book was released on 2012-12-06 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbides, nitrides and borides are families of related refractory materials. Traditionally they have been employed in applications associated with engineering ceramics where either high temperature strength or stability is of primary importance. In recent years there has been a growing awareness of the interesting electrical, thermal and optical properties exhibited by these materials, and the fact that many can be prepared as monolithic ceramics, single crystals and thin films. In practical terms carbides, nitrides and borides offer the prospect of a new generation of semiconductor materials, for example, which can function at very high temperatures in severe environmental conditions. However, as yet, we have only a limited understanding of the detailed physics and chemistry of the materials and how the preparation techniques influence the properties. Under the auspices of the NATO Science Committee an Advanced Research Workshop (ARW) was held on the Physics and Chemistry of Carbides, Nitrides and Borides (University of Manchester, 18-22 September, 1989) in order to assess progress to date and identify the most promising themes and materials for future research. An international group of 38 scientists considered developments in 5 main areas: The preparation of powders, monolithic ceramics, single crystals and thin films; Phase transformations, microstructure, defect structure and mass transport; Materials stability; Theoretical studies; Electrical, thermal and optical properties of bulk materials and thin films.
