The authors describe the theoretical work and practical results obtained in recent years in the area of classification of powders in moving flows. The promising nature of the cascade classification method is stressed. Mathematical models of regular, combined and irregular cascades are described. Mathematical fundamentals of the structural, dynamic and kinetics models of the process are presented. A new approach to optimising the classification processes, based on the classification curves and information theory, is explained. more...

This monograph provides a broad overview of the principles of design of advanced casting aluminium alloys. These materials continue to play a very important role in a number of fields, e.g. the automotive industry, machine engineering, marine construction, etc. The authors show that the development of novel casting aluminium alloys is impossible without understanding the corresponding phase diagrams, both equilibrium and non-equilibrium, and deep relationships existing among alloy thermodynamics, phase equilibria, and alloy microstructure. An important feature is the systematic review of such technological properties as castability, tendency to pre-solidification cracking, molten metal fluidity, and porosity, and the construction of “processing maps” or “windows” for materials with the best casting properties. Physical and mechanical properties of casting alloys are analyzed using different mathematical models, thus making it easier to draw systematic conclusions about the alloy properties and their changes. more...

ZEOCAT '95 is the eleventh in the series of symposia devoted to special fields of zeolite chemistry. Six plenary lectures, forty oral and forty-two poster presentations were included in the program. The accepted papers cover every aspect of catalysis on microporous materials. A significant number of the contributions describe the synthesis, modification, instrumental and chemical characterisation of zeolites and other micro- and mesoporous materials. Catalytic reactions involve hydrocarbon cracking, nucleophilic aromatic substitution, methanol to hydrocarbon conversion, hydration of acetylene, various alkylation reactions, redox transformations, Claisen rearrangement, etc. more...

"Cavity-Enhanced Spectroscopy" discusses the use of optical resonators and lasers to make sensitive spectroscopic measurements. This volume is written by the researcchers who pioneered these methods. The book reviews both the theory and practice behind these spectroscopic tools and discusses the scientific discoveries uncovered by these techniques. It begins with a chapter on the use of optical resonators for frequency stabilization of lasers, which is followed by in-depth chapters discussing cavity ring-down spectroscopy, frequency-modulated, cavity-enhanced spectroscopy, intracavity spectroscopies, microresonators and cavity-enhanced comb filters. This book is aimed towards a reader with a background in optics and spectroscopy, but who is unfamiliar with the methods discussed in the book. more...

Ceramics and ceramic composites are now used in almost all areas of technology and have potential for even greater and more widespread applications. To make this a reality, it is increasingly necessary to understand the microstructure of the material and its relationship with properties and performance. Central to this is the characterization of the material, in particular using optical and scanning electron microscopy techniques. This book acts as an expert guide to the various steps necessary for successful and accurate characterization of these materials including the crucially important preparation stage, the techniques used to reveal the microstructure and the analysis of the results. In particular, the book presents fundamental information on preparing polished sections of ceramics and ceramic composites including the main steps of sampling, sectioning, mounting and impregnation, and mechanical grinding, lapping and polishing. It discusses microstructural imaging in the optical microscope (OM) and the use of the scanning electron microscope (SEM). Etching or contrast enhancement following final polishing in order to reveal the material's microstructure is also covered. An entire chapter is devoted to material-specific preparation procedures for polished sections. These procedures take into account the properties of the ceramic or composite being examined and the purpose of the examination. They have proven to be very suitable for the respective materials and are effective for revealing the pores. The examples presented here for ceramics and ceramic composites provide polished sections of good to excellent quality for routine examination under the optical microscope. They include tips for etching and contrast enhancement, as well as microstructural images. Chapter 5 discusses the preparation of polished sections for purposes of examination and contains information on producing oblique sections and controlled removal of material. It also addresses the produc more...
