This book was released on 2000 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: CETTE ETUDE PRESENTE LA SYNTHESE PAR HYDROLYSE EN MILIEU POLYOL D'OXYDES ET DES HYDROXYACETATES LAMELLAIRES DE ZINC DE COBALT ET DE NICKEL ET LEUR CARACTERISATION STRUCTURALE (DRX ET IR RESOLUS EN TEMPERATURE, XANES, EXAFS, UV-VISIBLE) ET MORPHOLOGIQUE (MEB, TEM). ON SAVAIT QUE LES POLYOLS SONT DES MILIEUX FAVORABLES A LA SYNTHESE DE METAUX PAR REDUCTION. ON MONTRE ICI QU'ILS PEUVENT AUSSI ETRE PROPICES A LA SYNTHESE D'AUTRES MATERIAUX INORGANIQUES (OXYDES, SELS D'HYDROXYDES) PAR HYDROLYSE. NOUS AVONS PU METTRE EN EVIDENCE LE ROLE DETERMINANT DE L'ANION ASSOCIE AU METAL DANS LE COMPOSE DE DEPART ET EN PARTICULIER CELUI DE L'ANION ACETATE (QUI DECOULE DE SES PROPRIETES ACIDO-BASIQUES ET A SON POUVOIR COMPLEXANT) DANS LES REACTIONS MISES EN JEU. DANS CES MILIEUX REDUCTEURS, C'EST LE TAUX D'HYDROLYSE QUI APPARAIT COMME LE FACTEUR DETERMINANT POUR ORIENTER LA REACTION VERS LA FORMATION D'OXYDE PLUTOT QUE VERS LA REDUCTION EN METAL. PAR AILLEURS, NOUS AVONS MONTRE QUE LE TAUX D'HYDROLYSE INFLUE AUSSI SUR LE MODE DE CROISSANCE DES PARTICULES D'OXYDE. SON AUGMENTATION EMPECHE EN EFFET LA CROISSANCE PAR AGGREGATION DES PARTICULES PRIMAIRES ET FAVORISE EN REVANCHE LEUR CROISSANCE PAR DIFFUSION. UN MODELE STRUCTURAL A ETE PROPOSE POUR CHAQUE HYDROXYACETATE. CEUX DES COMPOSES AU ZINC ET AU COBALT DERIVENT DU TYPE HYDROZINCITE, ALORS QUE CELUI AU NICKEL EST CONSTITUE D'EMPILEMENT DE FEUILLETS DE TYPE BRUCITE. L'ANION ACETATE Y EST COORDONNE AUX CATIONS METALLIQUES DANS LES PHASES AU COBALT ET AU NICKEL, ALORS QU'IL EST INSERE ENTRE LES FEUILLETS DANS CELLE DU ZINC. L'EAU, ELLE, EST INSEREE EN MONOCOUCHE ENTRE LES FEUILLETS DANS LE CAS DU COBALT ET DU NICKEL, ALORS QU'ELLE EST LIEE AU CATION DANS L'HYDROXYACETATE DE ZINC. ENFIN, L'ETUDE MAGNETIQUE DES HYDROXYACETATES DE NICKEL ET DE COBALT ET DES HYDROXYCARBONATES CORRESPONDANTS OBTENUS PAR ECHANGE, A MIS EN EVIDENCE UN COMPORTEMENT D'AIMANT A BASSE TEMPERATURE, CE QUELLES QUE SOIENT LA STRUCTURE DES FEUILLETS, LEUR ESPACEMENT ET LA NATURE DU CATION.

Download or read book The Chemistry of the Actinide and Transactinide Elements 3rd ed Volumes 1 5 written by L.R. Morss and published by Springer Science & Business Media. This book was released on 2007-12-31 with total page 4059 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of the Actinide and Transactinide Elements is a contemporary and definitive compilation of chemical properties of all of the actinide elements, especially of the technologically important elements uranium and plutonium, as well as the transactinide elements. In addition to the comprehensive treatment of the chemical properties of each element, ion, and compound from atomic number 89 (actinium) through to 109 (meitnerium), this multi-volume work has specialized and definitive chapters on electronic theory, optical and laser fluorescence spectroscopy, X-ray absorption spectroscopy, organoactinide chemistry, thermodynamics, magnetic properties, the metals, coordination chemistry, separations, and trace analysis. Several chapters deal with environmental science, safe handling, and biological interactions of the actinide elements. The Editors invited teams of authors, who are active practitioners and recognized experts in their specialty, to write each chapter and have endeavoured to provide a balanced and insightful treatment of these fascinating elements at the frontier of the periodic table. Because the field has expanded with new spectroscopic techniques and environmental focus, the work encompasses five volumes, each of which groups chapters on related topics. All chapters represent the current state of research in the chemistry of these elements and related fields.

Download or read book Effect of Heavy Metal Pollution on Plants written by N. W. Lepp and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trace metals occur as natural constituents of the earth's crust, and are ever present constituents of soils, natural waters and living matter. The biological significance of this disparate assemblage of elements has gradually been uncovered during the twentieth century; the resultant picture is one of ever-increasing complexity. Several of these elements have been demonstrated to be essential to the functions of living organisms, others appear to only interact with living matter in a toxic manner, whilst an ever-decreasing number do not fall conveniently into either category. When the interactions between trace metals and plants are considered, one must take full account of the known chemical properties of each element. Consideration must be given to differences in chemical reactivity, solubility and to interactions with other inorganic and organic molecules. A clear understanding of the basic chemical properties of an element of interest is an essential pre-requisite to any subsequent consideration of its biological significance. Due consideration to basic chemical considerations is a theme which runs through the collection of chapters in both volumes.
Download or read book Rare Metal Technology 2020 written by Gisele Azimi and published by Springer Nature. This book was released on 2020-01-20 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection presents papers from a symposium on extraction of rare metals as well as rare extraction processing techniques used in metal production. Rare metals include strategic metals that are in increasing demand and subject to supply risks. Metals represented include neodymium, dysprosium, scandium and others; platinum group metals including platinum, palladium, iridium, and others; battery related metals including lithium, cobalt, nickel, and aluminum; electronics-related materials including copper and gold; and refectory metals including titanium, niobium, zirconium, and hafnium. Other critical materials such as gallium, germanium, indium and silicon are also included. Papers cover various processing techniques, including but not limited to hydrometallurgy (solvent extraction, ion exchange, precipitation, and crystallization), electrometallurgy (electrorefining and electrowinning), pyrometallurgy, and aeriometallurgy (supercritical fluid extraction). Contributions are focused on primary production as well as secondary production through urban mining and recycling to enable a circular economy. A useful resource for all involved in commodity metal production, irrespective of the major metal Provides knowledge of cross-application among industries Extraction and processing of rare metals that are the main building block of many emerging critical technologies have been receiving significant attention in recent years. The technologies that rely on critical metals are prominent worldwide, and finding a way to extract and supply them effectively is highly desirable and beneficial.

Download or read book Minerals as Advanced Materials II written by S V Krivovichev and published by Springer Science & Business Media. This book was released on 2011-12-01 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a collection of papers that are devoted to various aspects of interactions between mineralogy and material sciences. It will include reviews, perspective papers and original research papers on mineral nanostructures, biomineralization, micro- and nanoporous mineral phases as functional materials, physical and optical properties of minerals, etc. Many important materials that dominate modern technological development were known to mineralogists for hundreds of years, though their properties were not fully recognized. Mineralogy, on the other hand, needs new impacts for the further development in the line of modern scientific achievements such as bio- and nanotechnologies as well as by the understanding of a deep role that information plays in the formation of natural structures and definition of natural processes. It is the idea of this series of books to provide an arena for interdisciplinary discussion on minerals as advanced materials.
