Download or read book Diffusion in Solid Metals and Alloys Diffusion in festen Metallen und Legierungen written by H. Bakker and published by Springer. This book was released on 1990-12-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interest in diffusion in solids is as old as physical metallurgy or materials science. It stems from application-oriented as well as from scientific reasons. First, a knowledge of diffusion is basic to an understanding of many microstructural changes that occur in solid matter at elevated temperatures. For processes like phase transformations, precipitation or dissolution of a second phase, recrystallization, oxidation, creep, annealing etc., solid state diffusion is fundamental and ubiquitous. The second reason for studying diffusion is to learn more about how atoms move in solid matter. Volume III/26 presents for the first time a comprehensive collection of diffusion data for solid metals and alloys. The critical compilation of data has resulted in tables and series of diagrams which show in 13 chapters data for the following properties: Self- and impurity-diffusion in metallic elements, self-diffusion in homogeneous binary alloys, chemical diffusion in binary and ternary alloys, diffusion in amorphous alloys, diffusion of interstitial foreign atoms like hydrogen, carbon, oxygen and nitrogen in metallic elements, mass and pressure dependence of diffusion, diffusion along dislocations, grain and interphase boundary diffusion, and diffusion on surfaces.

Download or read book A Determination of Diffusion Coefficients for Gaseous Systems at Various Temperatures written by Roger A. Strehlow and published by . This book was released on 1950 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transport property which is most fundamentally related to forces between unlike molecules is the ordinary diffusion due to concentration gradients. Unfortunately, this property and its dependence upon temperature have not been systematically studied experimentally, with the result that the literature does not contain the data necessary to obtain good force constants for the introduction of unlike molecuels. The present work describes an experimental method for determining diffusion coefficients, based on the variation of thermal conductivity with composition in binary mixtures which is capable of being used over a wide range of temperature. Experimental results for the systems n-butane-hydrogen, sulfur hexafluoride-hydrogen, argon-hydrogen, and argon-helium are given for a temperature range from 10°C. to 140°C.

Available in PDF, EPUB and Kindle. Book excerpt: This overview of diffusion and separation processes brings unsurpassed, engaging clarity to this complex topic. Diffusion is a key part of the undergraduate chemical engineering curriculum and at the core of understanding chemical purification and reaction engineering. This spontaneous mixing process is also central to our daily lives, with importance in phenomena as diverse as the dispersal of pollutants to digestion in the small intestine. For students, Diffusion goes from the basics of mass transfer and diffusion itself, with strong support through worked examples and a range of student questions. It also takes the reader right through to the cutting edge of our understanding, and the new examples in this third edition will appeal to professional scientists and engineers. Retaining the trademark enthusiastic style, the broad coverage now extends to biology and medicine.

Download or read book Diffusion Processes written by Merkel H. Jacobs and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: A basic tenet of present day biophysics is that flows in biological systems are causally related to forces. A large and growing fraction of membrane biophysics is devoted to an exploration of the quantitative relationship between forces and flows in order to understand both the nature of biological membranes and the processes that take place on and in these membranes. This is why the discussion of the nature of diffusion is so important in any formal development of membrane bio physics. This was equally true twenty years ago when tracers were just beginning to be used for the measurement of m.

Download or read book Comprehensive Chirality written by and published by Newnes. This book was released on 2012-12-31 with total page 5635 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although many books exist on the subject of chiral chemistry, they only briefly cover chiral synthesis and analysis as a minor part of a larger work, to date there are none that pull together the background information and latest advances in one comprehensive reference work. Comprehensive Chirality provides a complete overview of the field, and includes chiral research relevant to synthesis, analytic chemistry, catalysis, and pharmaceuticals. The individual chapters in each of the 9 volumes provide an in depth review and collection of references on definition, technology, applications and a guide/links to the related literature. Whether in an Academic or Corporate setting, these chapters will form an invaluable resource for advanced students/researchers new to an area and those who need further background or answers to a particular problem, particularly in the development of drugs. Chirality research today is a central theme in chemistry and biology and is growing in importance across a number of disciplinary boundaries. These studies do not always share a unique identifying factor or subject themselves to clear and concise definitions. This work unites the different areas of research and allows anyone working or researching in chiral chemistry to navigate through the most essential concepts with ease, saving them time and vastly improving their understanding. The field of chirality counts several journals that are directly and indirectly concerned with the field. There is no reference work that encompasses the entire field and unites the different areas of research through deep foundational reviews. Comprehensive Chirality fills this vacuum, and can be considered the definitive work. It will help users apply context to the diverse journal literature offering and aid them in identifying areas for further research and/or for solving problems. Chief Editors, Hisashi Yamamoto (University of Chicago) and Erick Carreira (ETH Zürich) have assembled an impressive, world-class team of Volume Editors and Contributing Authors. Each chapter has been painstakingly reviewed and checked for consistent high quality. The result is an authoritative overview which ties the literature together and provides the user with a reliable background information and citation resource.

Download or read book The Effect of Concentration on Diffusion Coefficients in Binary Systems written by Kumbla Narasimha Srinivas Prabhu and published by . This book was released on 1966 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diffusion coefficients were determined for the chloroform-air system at 50°C and for the methanol-air system at 55°C by the Arnold cell technique. The effect of concentration was studied by varying the concentration of the gas stream passing across the top of the Arnold cell. The chloroform-air system exhibited a strong dependency on concentration; for this system the diffusion coefficient changed by approximately ten percent as the chloroform concentration in the gas stream was changed from zero to 56 percent. The variation of the diffusion coefficient in the methanol-air system was small; a total variation of one percent was observed over the concentration range of zero to 46 percent methanol. Since the variation of diffusion coefficient for methanol-air system was of the order of one percent, assumption of constancy of diffusion coefficient with concentration would cause little error in design calculations; hence, no correlation was attempted for the methanol-air system. However attempts were made to correlate the concentration dependency of diffusion coefficients in the chloro form-air system. It was found that a quadratic functional relationship in concentration for the diffusion coefficients was the best possible correlation. A quadratic function in weight fraction was used to account for the effect of molecular weight differences. It was concluded that the difference in molecular weight of the two diffusing species has a pronounced effect on the variation of diffusion coefficients with concentration.
