Download or read book Synth se et caract risation de polym res de coordination pr sentant des propri t s redox written by Thi Le Anh Nguyen and published by . This book was released on 2010 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette thèse porte sur la synthèse et les caractérisations structurales et physico-chimiques de nouveaux polymères de coordination cristallins (encore appelés MOFs), poreux ou non, qui possèdent des propriétés redox. Deux approches ont été mis en oeuvre pour préparer de tels matériaux, soit en utilisant un ligand actif (l’acide TétraThiaFulvalène TétraCarboxylique, (TTF-TC)H4) soit un cation métallique actif (le titane). La synthèse hydro- ou solvo-thermale classique a permis de produire des solides dans lesquels le centre redox présente son degré d’oxydation habituel (TTF0,TiIV). Leurs caractéristiques structurales, ainsi que leurs propriétés de stabilité thermique et de porosité ont été étudiées. Leur propriétés redox ont quant à elles été mises à profit par des réactions post-synthèse (photo-réduction, utilisation comme électrode de batterie au lithium). Enfin, le couplage électrocristallisation / synthèse hydrothermale a permis de produire un solide dans lequel le ligand TTF-TC se trouve à l’état oxydé +1. Les propriétés de ce solide, notamment celles de conduction électronique ont été évaluées.

Download or read book Food Chemistry Research Developments written by Konstantinos N. Papadopoulos and published by Nova Publishers. This book was released on 2008 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food chemistry is the study of chemical processes and interactions of all biological and non-biological components of foods. The biological substances include such items as meat, poultry, lettuce, beer, and milk as examples. It is similar to biochemistry in its main components such as carbohydrates, lipids, and protein, but it also includes areas such as water, vitamins, minerals, enzymes, food additives, flavours, and colours. This discipline also encompasses how products change under certain food processing techniques and ways either to enhance or to prevent them from happening. An example of enhancing a process would be to encourage fermentation of dairy products with lactic acid; an example of a preventing process would be stopping the Maillard reaction on the surface of freshly cut Red Delicious apples whether by hand or mechanical methods. This book presents the recent research from around the world in this field.

Download or read book The Philosophy of Chemistry written by Jean-Pierre Llored and published by Cambridge Scholars Publishing. This book was released on 2014-09-26 with total page 780 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume connects chemistry and philosophy in order to face questions raised by chemistry in our present world. The idea is first to develop a kind of philosophy of chemistry which is deeply rooted in the exploration of chemical activities. We thus work in close contact with chemists (technicians, engineers, researchers, and teachers). Following this line of reasoning, the first part of the book encourages current chemists to describe their workaday practices while insisting on the importance of attending to methodological, metrological, philosophical, and epistemological questions related to their activities. It deals with sustainable chemistry, chemical metrology, nanochemistry, and biochemistry, among other crucial topics. In doing so, those chemists invite historians and philosophers to provide ideas for future developments. In a nutshell, this part is a call for forthcoming collaborations focused on instruments and methods, that is on ways of doing chemistry. The second part of the book illustrates the multifarious ways to study chemistry and even proposes new approaches to doing so. Each approach is interesting and incomplete but the emergent whole is richer than any of its components. Analytical work needs socio-historical expertise as well as many other approaches in order to keep on investigating chemistry to greater and greater depth. This heterogeneity provides a wide set of methodological perspectives not only about current chemical practices but also about the ways to explore them philosophically. Each approach is a resource to study chemistry and to reflect upon what doing philosophy of science can mean. In the last part of the volume, philosophers and chemists propose new concepts or reshape older ones in order to think about chemistry. The act of conceptualization itself is queried as well as the relationships between concepts and chemical activities. Prefaced by Nobel Laureate in Chemistry, Roald Hoffmann, and by the President of the International Society for the Philosophy of Chemistry, Rom Harré, this volume is a plea for the emergence of a collective cleverness and aims to foster inventiveness.

Download or read book Process Engineering and Industrial Management written by Jean-Pierre Dal Pont and published by John Wiley & Sons. This book was released on 2013-03-04 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Process Engineering, the science and art of transforming raw materials and energy into a vast array of commercial materials, was conceived at the end of the 19th Century. Its history in the role of the Process Industries has been quite honorable, and techniques and products have contributed to improve health, welfare and quality of life. Today, industrial enterprises, which are still a major source of wealth, have to deal with new challenges in a global world. They need to reconsider their strategy taking into account environmental constraints, social requirements, profit, competition, and resource depletion. “Systems thinking” is a prerequisite from process development at the lab level to good project management. New manufacturing concepts have to be considered, taking into account LCA, supply chain management, recycling, plant flexibility, continuous development, process intensification and innovation. This book combines experience from academia and industry in the field of industrialization, i.e. in all processes involved in the conversion of research into successful operations. Enterprises are facing major challenges in a world of fierce competition and globalization. Process engineering techniques provide Process Industries with the necessary tools to cope with these issues.

Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer. This book was released on 1976 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis· seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac· tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 20 (thesis year 1975) a total of 10,374 theses titles from 28 Canadian and 239 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 20 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.
