This book was released on 1998 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: CETTE ETUDE PORTE SUR LA REACTIVITE DU SOUS-OXYDE DE CARBONE ADSORBE SUR DES FILMS DE GLACE ENTRE 80 ET 170 K EN ABSENCE ET EN PRESENCE DE HCL. PREALABLEMENT A L'ETUDE SUR LA GLACE, L'ETUDE DES COMPLEXES 1 : 1 DU SOUS-OXYDE DE CARBONE AVEC H#2O ET HCL A EGALEMENT ETE REALISEE EN MATRICE COUPLEE A LA SPECTROMETRIE INFRAROUGE AFIN DE PREDIRE UNE EVENTUELLE REACTIVITE. LES INTERACTIONS DU C#3O#2 AVEC DES SURFACES DE GLACES AMORPHES OU CRISTALLINES ONT ETE ETUDIEES EN UTILISANT LA TECHNIQUE DE DESORPTION PROGRAMMEE EN TEMPERATURE. NOUS AVONS MONTRE QUE CONTRAIREMENT A DE LA GLACE CRISTALLINE DANS UN DOMAINE DE TEMPERATURE COMPRIS ENTRE 125 ET 145 K, L'ADSORBAT RECOUVRE LA SURFACE DE GLACE AMORPHE QUI PRESENTE UN ETAT PROCHE DE LA MONOCOUCHE DANS LEQUEL C#3O#2 FORME UNE LIAISON HYDROGENE AVEC LES OH LIBRES DE SURFACE. LA DESORPTION DU C#3O#2 A PARTIR DU FILM DE GLACE AMORPHE SEMBLE INDUITE PAR LA CRISTALLISATION DE LA GLACE AMORPHE EN GLACE CUBIQUE. L'ENERGIE D'ACTIVATION DE DESORPTION MESUREE A PARTIR D'UNE CINETIQUE DU PREMIER ORDRE EST DE L'ORDRE DE 43 KJ.MOL##1. CETTE VALEUR EST COHERENTE AVEC L'EXISTENCE D'UN ETAT ADSORBE LIE PAR LIAISON HYDROGENE. L'ADSORPTION DE C#3O#2 SUR DES SURFACES AMORPHES D'HYDRATE DE HCL, FORMEES MAJORITAIREMENT D'ESPECES IONIQUES (H#3O#+(H#2O)#N##1CL#) OBTENUES PAR CODEPOSITION DE MELANGE GAZEUX DE HCL ET DE H#2O, MONTRE QUE POUR DES TEMPERATURES SUPERIEURES OU EGALE A 80 K, IL EXISTE UNE REACTION ENTRE C#3O#2 ET HCL. LE PREMIER PRODUIT DE REACTION APPARAISSANT A 85 K EST ATTRIBUE AU CHLOROFORMYLCETENE ALORS QUE LE SECOND EST IDENTIFIE A DU DICHLORURE DE MALONYLE PAR COMPARAISON AVEC LEURS SPECTRES INFRAROUGE. LES RESULTATS MONTRENT QUE LE MONOHYDRATE H#3O#+CL# EST PLUS REACTIF QUE LES HYDRATES D'ORDRE SUPERIEUR. LES REACTIONS SONT DECRITES PAR UN MECANISME IONIQUE CATALYSE PAR LA GLACE ET SE PRODUISANT EN SURFACE.

This book was released on 2005 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le travail présenté dans cette thèse a pour objet l'étude de la liaison hydrogène dans les alcools en conditions supercritiques. Des expériences de spectroscopies infrarouge et Raman ontt été réalisées sur trois alccols (méthanol, éthanol et tert-butanol) dans une large gamme de pressions (de 0.1 à 25 Mpa), le long de l'isotherme 523 K, permettant d'explorer un domaine de densités réduites compris entre 0.1 et 2. Le domaine spectral associé à la vibration d'élongation O-H de ces alcools a été analysé à l'aide d'un modèle original d'agrégats, conduisant à une information quantitative de l'état d'agrégation dans ces systèmes. Parallèlement aux expériences, des expériences, de simulations de dynamique molèculaire ont apporté de nombreuses informations au niveau microscopique, démontrent notamment la pertinence du modèle d'agrégats proposé. Les populations des diverses espèces observées ainsi que leurs temps de vie ont également été examinés en détail.

Download or read book Adhesion Between Polymers and Concrete Adh sion Entre Polym res Et B ton written by H. R. Sasse and published by Springer. This book was released on 1986 with total page 792 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

Download or read book An Introduction to Differential Manifolds written by Jacques Lafontaine and published by Springer. This book was released on 2015-07-29 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to differential manifolds. It gives solid preliminaries for more advanced topics: Riemannian manifolds, differential topology, Lie theory. It presupposes little background: the reader is only expected to master basic differential calculus, and a little point-set topology. The book covers the main topics of differential geometry: manifolds, tangent space, vector fields, differential forms, Lie groups, and a few more sophisticated topics such as de Rham cohomology, degree theory and the Gauss-Bonnet theorem for surfaces. Its ambition is to give solid foundations. In particular, the introduction of “abstract” notions such as manifolds or differential forms is motivated via questions and examples from mathematics or theoretical physics. More than 150 exercises, some of them easy and classical, some others more sophisticated, will help the beginner as well as the more expert reader. Solutions are provided for most of them. The book should be of interest to various readers: undergraduate and graduate students for a first contact to differential manifolds, mathematicians from other fields and physicists who wish to acquire some feeling about this beautiful theory. The original French text Introduction aux variétés différentielles has been a best-seller in its category in France for many years. Jacques Lafontaine was successively assistant Professor at Paris Diderot University and Professor at the University of Montpellier, where he is presently emeritus. His main research interests are Riemannian and pseudo-Riemannian geometry, including some aspects of mathematical relativity. Besides his personal research articles, he was involved in several textbooks and research monographs.

Download or read book Aeronomy written by P. M. Banks and published by Elsevier. This book was released on 2013-09-24 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aeronomy, Part A is an attempt to make a comprehensive exposition of the processes in aeronomy, the study of composition, movement, and thermal balance of the upper regions of the planetary atmosphere. The text covers topics such as atmospheric regions and atmospheric density, the temperature and molecular mass of the atmosphere; the permanent constituents and the molecular and isotonic composition of the homosphere; and the transition from the homosphere to the heterosphere. Also covered are topics such as the temperature gradient and energies in the thermosphere, conditions at 200km and above 250km, solar radiation and ionization, and aeronomic reactions. The book is recommended for scientists, especially natural physicists, who would like to know more about the field of aeronomy and its advances.
