Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL CONSTITUE UNE CONTRIBUTION A L'ETUDE THERMODYNAMIQUE DU SYSTEME TERNAIRE U-FE-O. LA CONNAISSANCE DES RELATIONS DE PHASES DE CE SYSTEME PASSE EN PREMIER LIEU PAR LA CONNAISSANCE DES SYSTEMES BINAIRES DE BASE U-O, FE-O ET U-FE. UN EXAMEN DE LA LITTERATURE SUR LES SYSTEMES U-O ET U-FE A MONTRE QUE LES DIAGRAMMES DE PHASE ET LES DONNEES THERMODYNAMIQUES ASSOCIEES ETAIENT INCOMPLETS. UNE ANALYSE CRITIQUE DE LA BIBLIOGRAPHIE DU SYSTEME UO 2-UO 3 A ETE REALISEE AFIN DE CONSTRUIRE UNE NOUVELLE BASE DE DONNEES QUI A CONDUIT A L'OPTIMISATION DE CE SYSTEME PAR LE LOGICIEL THERMO-CALC. PARALLELEMENT, UNE ETUDE CALORIMETRIQUE A ETE EFFECTUEE SUR LES COMPOSES DEFINIS UFE 2 ET U 6FE. CES NOUVELLES DONNEES THERMODYNAMIQUES, ONT PERMIS DE PROPOSER UNE NOUVELLE OPTIMISATION DU SYSTEME U-FE. L'ETUDE DU SYSTEME TERNAIRE U-FE-O A ETE ENTREPRISE EN ETABLISSANT LA SECTION ISOTHERME A 1300 K. LES PHASES OBTENUES ONT ETE CARACTERISEES PAR DRX, MICROSCOPIE ELECTRONIQUE EN TRANSMISSION, MEB ET MICROSONDE. EN RAISON DES LIMITES DE CES TECHNIQUES, IL A ETE NECESSAIRE D'INTERPRETER LES RESULTATS SUR LA BASE DES DONNEES THERMODYNAMIQUES ET EN PARTICULIER DES POTENTIELS D'OXYGENE. POUR COMPLETER, CES DONNEES DE DIAGRAMME DE PHASE, LE POTENTIEL D'OXYGENE D'EQUILIBRE DE CERTAINS DOMAINES TRIPHASES A ETE DETERMINE PAR THERMOGRAVIMETRIE. DE PLUS, UNE ETUDE THERMODYNAMIQUE ET STRUCTURALE A ETE FAITE SUR LE COMPOSE UFEO 4. SA STRUCTURE, DEJA ETABLIE, A ETE CONFIRMEE ; SON ENTHALPIE DE FORMATION ET SA CAPACITE THERMIQUE ONT ETE MESUREES PAR CALORIMETRIE. DES ANALYSES DE DRX A HAUTE TEMPERATURE ONT PERMIS DE STATUER SUR LA STABILITE THERMIQUE DE CE MATERIAU ET DE METTRE EN EVIDENCE L'EXISTENCE D'UN NOUVEL OXYDE TERNAIRE UFEO 4 . 5, DONT LA STRUCTURE A ETE ETABLIE DANS CETTE ETUDE. L'ENSEMBLE DE CES DONNEES ORIGINALES PERMETTENT DE CORRELER LES TROIS SYSTEMES BINAIRES AVEC LE TERNAIRE ET AINSI DE PROPOSER UNE DESCRIPTION REALISTE DU DIAGRAMME DE PHASE U-FE-O EN PHASE SOLIDE.

Available in PDF, EPUB and Kindle. Book excerpt: III-V semiconductors have attracted considerable attention due to their applications in the fabrication of electronic and optoelectronic devices as light-emitting diodes and solar cells. Because of their wide applications in a variety of devices, the search for new semiconductor materials and the improvement of existing materials is an important field of study. This new book covers all known information about phase relations in ternary systems based on III-V semiconductors. This book will be of interest to undergraduate and graduate students studying materials science, solid state chemistry, and engineering. It will also be relevant for researchers at industrial and national laboratories, in addition to phase diagram researchers, inorganic chemists, and solid state physicists.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Today large numbers of geoscientists apply thermodynamic theory to solu tions of a variety of problems in earth and planetary sciences. For most problems in chemistry, the application of thermodynamics is direct and rewarding. Geoscientists, however, deal with complex inorganic and organic substances. The complexities in the nature of mineralogical substances arise due to their involved crystal structure and multicomponental character. As a result, thermochemical solutions of many geological-planetological problems should be attempted only with a clear understanding of the crystal-chemical and thermochemical character of each mineral. The subject of physical geochemistry deals with the elucidation and application of physico-chemical principles to geosciences. Thermodynamics of mineral phases and crystalline solutions form an integral part of it. Developments in mineralogic thermody namics in recent years have been very encouraging, but do not easily reach many geoscientists interested mainly in applications. This series is to provide geoscientists and planetary scientists with current information on the develop ments in thermodynamics of mineral systems, and also provide the active researcher in this rapidly developing field with a forum through which he can popularize the important conclusions of his work. In the first several volumes, we plan to publish original contributions (with an abundant supply of back ground material for the uninitiated reader) and thoughtful reviews from a number of researchers on mineralogic thermodynamics, on the application of thermochemistry to planetary phase equilibria (including meteorites), and on kinetics of geochemical reactions.
