Book Description
Between June 6-10, 1988, the Third Chemical Congress of North America was held at the Toronto Convention Center. At this rare gathering, fifteen thousand scientists attended various symposia. In one of the symposia, Professor Pierre-Gilles de Gennes of College de France was honored as the 1988 recipient of the Amer ican Chemical Society Polymer Chemistry Award, sponsored by Mobil Chemical Corporation. For Professor de Gennes, this international setting could not be more fitting. For years, he has been a friend and a lecturer to the world scientific community. Thus, for this special occasion, his friends came to recount many of his achievements or report new research findings mostly derived from his theories or stimulated by his thoughts. In this volume of Proceedings, titled New Trends in Physics and Physical Chemistry of Polymers, we are glad to present the revised papers for the Symposium and some contributed after the Symposium. In addition, we intend to include most of the lively discussions that took plaGe during the conference. This volume contains a total of thirty-six papers divided into six parts, primarily according to the nature of the subject matter: • Adsorption of Colloids and Polymers. • Adhesion, Fractal and Wetting of Polymers. • Dynamics and Characterization of Polymer Solutions. • Diffusion and Interdiffusion of Polymers. • Entanglement and Reptation of Polymer Melts and Networks. • Phase Transitions and Gel Electrophoresis.

Book Description
Cette thèse se divise en deux volets: un premier volet axé chimie du solide où nous avons exploré des systèmes ciblés Ba-Co-O(X) (X = F) autour de trois composés inédits Ba6Co6FO16, Ba5Co5FO13 et Ba2Co9O14. Les propriétés fondamentales des composés: structures à température ambiante, mise en ordre magnétique à basse température (susceptibilités et structures magnétiques), comportement thermique et électrique ... ont été étudiées. Les cobaltites étant considérées comme potentiellement intéressantes pour une utilisation comme matériau de cathode pour SOFC, le deuxième volet de cette thèse a pour objectif la caractérisation électrochimique de ces phases. L'étude des matériaux de cathode étant nouvelle au laboratoire, pour nous « faire la main », nous avons étudié les phases pyrochlores Bi2-xMxRu2O7-o[delta] (M = Pb, Sr) dont la solution solide au strontium est inédite. Les phases Bi2Ru2O7 et Pb2Ru2O6.5 ayant fait l'objet de nombreuses caractérisations comme matériau de cathode pour SOFC, l'étude menée sur les solutions solides au plomb et au strontium a permis de confronter les résultats obtenus à ceux de la littérature. Enfin, la technique utilisée a été appliquée à nos composés inédits présentés en première partie. La spectroscopie d'impédance sous air et sous différentes pressions partielles d'oxygène nous a permis de mettre en évidence les différents phénomènes qui interviennent au cours de la réaction d'électrode et les bonnes performances de nos composés.

Book Description
La filiation avec les phases a 2v 3o 9 (m = pb,sr,ba) permet d'envisager la preparation de nombreux vanadates par condensation des vo 4. _ l'oxyde pb 3mn 5v 2o 1 6 possede une structure resultant de la succession de couches compactes de formules o 4 et pbo 3. Des blocs pbo 3-o 4-o 4-pbo 3 sont separes par des couches lacunaires pbo 2. Les atomes de vanadium occupent les sites tetraedriques entre les couches pbo 3 et pbo 2. Les atomes de manganese occupent deux sites cristallographiques differents. Les distances interatomiques et les sommes des valences de liaison permettent d'attribuer sans ambiguite les degres d'oxydation +4 et +2 aux deux types de manganese. La structure est comparee a celles des phases du type magnetoplombite et pbv 6o 1 1.
Book Description
Des bronzes de structure type hollandite ont ete isoles et caracterises dans les systemes bi-v-o et pb-v-o. Dans le cas du bismuth, la phase bi#1#,#7v#8o#1#6 a ete etudiee par diffraction x sur monocristal, le bismuth occupe au sein des tunnels du squelette v#8o#1#6 une place originale ; sa coordination est quasi plan-carre. Ce compose constitue le premier exemple de hollandite au bismuth. Les phases a cations mixtes (bi,k)#xv#8o#1#6 ont ete preparees par voie solide. Dans le cas du plomb, la deformation monoclinique de la maille est liee a une occupation complexe des tunnels du squelette v#8o#1#6 par des ions pb#2#+ au centre des tunnels, des ions pb#2#+ accroches sur les parois et des tetraedres vo#4 excentres. Ces materiaux manifestent une semi-conductivite qui reflete vraisemblablement la presence simultanee de vanadium aux nombres d'oxydation 3 et 4. Le compose a valence mixte pbv#6o#1#1 a egalement ete isole: sa structure est constituee de blocs r rencontres dans les ferrites hexagonales telles que bafe#1#2o#1#9. Enfin, la phase inedite bi#9v#2c1o#1#8 a ete obtenue lors d'essais de synthese de monocristaux d'oxydes mixtes. La substitution des groupements vo#4#3#- par des ions po#4#3#- isosteriques conduit a la solution solide totale bi#9(v#1#-#xp#x)#2c1o#1#8. Cette derniere manifeste une conductivite electrique que les donnees structurales permettent de relier a une mobilite des ions c1-.

Book Description
By browsing about 10 000 000 scientific articles of over 200 major journals mainly in a 'cover to cover approach' some 200 000 publications were selected. The extracted data is part of the following fundamental material research fields: crystal structures (S), phase diagrams (also called constitution) (C) and the comprehensive field of intrinsic physical properties (P). This work has been done systematically starting with the literature going back to 1900. The above mentioned research field codes (S, C, P) as well as the chemical systems investigated in each publication were included in the present work. The aim of the Inorganic Substances Bibliography is to provide researchers with a comprehensive compilation of all up to now published scientific publications on inorganic systems in only three handy volumes.

Book Description
Nanostructured materials with tailored properties are regarded as a fundamental element in the development of future science and technology. Research is still ongoing into the nanosized construction elements required to create functional solids. The recently developed technique, nanocasting, has great advantage over others in terms of the synthesis of special nanostructured materials by the careful choice of suitable elements and nanoengineering steps. This new book summarizes the recent developments in nanocasting, including the principles of nanocasting, syntheses of novel nanostructured materials, characterization methods, detailed synthetic recipes and further possible development in this area. The book focuses on the synthesis of porous solids from the viewpoint of methodology and introduces the science of nanocasting from fundamental principles to their use in synthesis of various materials. It starts by outlining the principles of nanocasting, requirements to the templates and precursors and the tools needed to probe matter at the nanoscale level. It describes how to synthesize nano structured porous solids with defined characteristics and finally discusses the functionalization and application of porous solids. Special attention is given to new developments in this field and future perspectives. A useful appendix covering the detailed synthetic recipes of various templates including porous silica, porous carbon and colloidal spheres is included which will be invaluable to researchers wanting to follow and reproduce nanocast materials. Topics covered in the book include: * inorganic chemistry * organic chemistry * solution chemistry * sol-gel and interface science * acid-base equilibria * electrochemistry * biochemistry * confined synthesis The book gives readers not only an overview of nanocasting technology, but also sufficient information and knowledge for those wanting to prepare various nanostructured materials without needing to search the available literature.
