Book excerpt: L’objectif de notre travail, était l’étude de deux classes de catalyseurs dans la réaction d’oxydation totale de COV. L’application visée étant la destruction à basse température de ces traces de polluants dans l’air. Des oxydes mixtes Co3O4-CeO2 ont été préparés par co-précipitation. Avec l’oxyde mixte (% atomique Co/Ce = 1), nous avons obtenu les meilleures performances catalytiques et montré que la réactivité étaient exaltée par une forte mobilité des oxygènes de coeur. Des catalyseurs à base d’or (2wt%) et de palladium (1wt%) ont été déposés sur des supports oxydes comme la cérine et le titane afin de favoriser une interaction métal support, ou sur un support alumine. Des solides à base d’alumine dopée au cérium, manganèse, fer et titane ont également été préparés. Pour l’or, l’évolution des performances catalytiques en fonction du support ont été les suivantes: Au2%/Al2O3

Book Synopsis DESTRUCTION CATALYTIQUE DE COMPOSES ORGANIQUES VOLATILS (C.O.V.) CHLORES SUR OXYDES MIXTES by : GILLES.. SINQUIN
Download or read book DESTRUCTION CATALYTIQUE DE COMPOSES ORGANIQUES VOLATILS (C.O.V.) CHLORES SUR OXYDES MIXTES written by GILLES.. SINQUIN and published by . This book was released on 1998 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: LA DIMINUTION DES EMISSIONS DES COMPOSES ORGANIQUES VOLATILS (C.O.V.) ET EN PARTICULIER DES C.O.V. CHLORES EST UN DES OBJECTIFS DES PRINCIPAUX PAYS INDUSTRIALISES. LA DESTRUCTION CATALYTIQUE EST UNE VOIE PERMETTANT D'ATTEINDRE CET OBJECTIF ET CONSTITUE UNE ALTERNATIVE A L'INCINERATION THERMIQUE GRANDE CONSOMMATRICE D'ENERGIE. DANS CE TRAVAIL, NOUS AVONS ETUDIE LA DESTRUCTION CATALYTIQUE DE DIFFERENTS C.O.V. CHLORES (C#1, C#2, CHLOROBENZENE) SUR DES CATALYSEURS DE TYPE PEROVSKITE (ABO#3) PREPARES PAR UNE METHODE DERIVEE DES SOLGEL. PARMI CEUX-CI, LACOO#3 ET LAMNO#3, PRESENTANT LES ACTIVITES LES PLUS ELEVEES, ONT FAIT L'OBJET D'UNE ETUDE APPROFONDIE. NOUS AVONS MONTRE, QUE SUIVANT LA NATURE DE LA MOLECULE CHLOREE, LES MECANISMES DE DESTRUCTION SONT DIFFERENTS. L'ADDITION D'EAU PERMET DE FAVORISER LES REACTIONS D'HYDROLYSE PAR RAPPORT AUX REACTIONS D'OXYDATION. L'EFFET DE L'EAU EST D'AUTANT PLUS IMPORTANT QUE LE RAPPORT H/CL DE LA MOLECULE TESTEE EST FAIBLE. L'EAU PERMET EGALEMENT DE DESORBER LES ATOMES DE CHLORE PRESENTS A LA SURFACE DU CATALYSEUR CE QUI LIMITE LA QUANTITE DE SOUS-PRODUITS CHLORES FORMES. L'EFFET BENEFIQUE DE L'EAU EST MOINS MARQUEE SUR LACOO#3 QUE SUR LAMNO#3 ET PAR CONSEQUENT LA FORMATION DE SOUS-PRODUITS EST PLUS IMPORTANTE SUR LACOO#3. NOUS AVONS EGALEMENT MONTRE PAR DIFFERENTES TECHNIQUES (XPS, XRD, MEB, IR-TF) QUE LACOO#3 SE TRANSFORME AU COURS DE LA REACTION EN LAOCLI ET CO#3O#4 ALORS QUE LAMNO#3 NE SEMBLE PAS ETRE MODIFIEE DANS LES MEMES CONDITIONS. CETTE DESTRUCTION DE LA STRUCTURE PEROVSKITE ENTRAINE UNE DESACTIVATION PLUS OU MOINS IMPORTANTE SUIVANT LA MOLECULE TESTEE. CETTE DIFFERENCE EST LIEE A LA STABILITE THERMODYNAMIQUE PLUS GRANDE DE LA STRUCTURE LAMNO#3 PAR RAPPORT A LACOO#3. ENFIN, NOUS AVONS MONTRE QU'IL ETAIT POSSIBLE D'ACCROITRE L'ACTIVITE DES PEROVSKITES EN LES DISPERSANT SUR DES SUPPORTS DE SURFACE SPECIFIQUE ELEVEE.

Book Synopsis Cyclodextrin Applications in Medicine, Food, Environment and Liquid Crystals by : Sophie Fourmentin
Download or read book Cyclodextrin Applications in Medicine, Food, Environment and Liquid Crystals written by Sophie Fourmentin and published by Springer. This book was released on 2018-06-22 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the second volume of two volumes on cyclodextrins published in the series Environmental Chemistry for a Sustainable World. This volume focuses on cyclodextrin applications. The first chapter by Divya Arora and Sundeep Jaglan presents cyclodextrin-based carriers for delivery of dietary phytochemicals. The second chapter by Éva Fenyvesi et al. describes the interactions of steroids with cyclodextrins and their applications to pharmaceuticals, food, biotechnology and environment. Nazli Erdoğar and Erem Bilensoy discuss cyclodextrin-based nanosystems in targeted cancer therapy. Miriana Kfoury et al. review the use of cyclodextrins for essential oils applications in chapter 4. Hiroshi Ikeda demonstrates in chapter 5 that chromophore-appended cyclodextrins are effective for chemosensors to detect organic molecules by fluorescence or absorbance changes. Then Grégorio Crini et al. describe silica materials-containing cyclodextrin for pollutant removal. The final chapter by Chang-Chun Ling et al. summarizes the synthesis and characterization of supramolecular liquid crystals based on cyclodextrins and their applications.
Book Synopsis Masters Theses in the Pure and Applied Sciences by : Wade H. Shafer
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.

Book Synopsis Sediment Quality Assessment by : Graeme Batley
Download or read book Sediment Quality Assessment written by Graeme Batley and published by CSIRO PUBLISHING. This book was released on 2016-02-01 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contaminated sediments represent an ongoing threat to the health of aquatic ecosystems. The assessment of sediment quality is, therefore, an important concern for environmental regulators. Sediment quality guidelines are now well established in regulatory frameworks worldwide; however, practical guidance that covers all of the key aspects of sediment quality assessment is not readily available. In 2005, CSIRO published its highly cited Handbook for Sediment Quality Assessment. In the ensuing period, the science has advanced considerably. This practical guide is a revised and much expanded second edition, which will be a valuable tool for environmental practitioners. Written by experts in the field, it provides coverage of: sediment sampling; sample preparation; chemical analysis; ecotoxicology; bioaccumulation; biomarkers; and ecological assessment. In addition, detailed appendices describe protocols for many of the tests to be used.

Download or read book Routledge International Handbook of Ignorance Studies written by Matthias Gross and published by Routledge. This book was released on 2015-05-15 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once treated as the absence of knowledge, ignorance today has become a highly influential topic in its own right, commanding growing attention across the natural and social sciences where a wide range of scholars have begun to explore the social life and political issues involved in the distribution and strategic use of not knowing. The field is growing fast and this handbook reflects this interdisciplinary field of study by drawing contributions from economics, sociology, history, philosophy, cultural studies, anthropology, feminist studies, and related fields in order to serve as a seminal guide to the political, legal and social uses of ignorance in social and political life.
