Available in PDF, EPUB and Kindle. Book excerpt: LA CONNAISSANCE DES COEFFICIENTS D'ACCOMMODATION MASSIQUE, CARACTERISANT L'EFFICACITE DES COLLISIONS GAZ/LIQUIDE EST UNE NECESSITE POUR LE DEVELOPPEMENT DE MODELES PREDICTIFS DE LA PHYSICO-CHIMIE ATMOSPHERIQUE. AINSI, CE TRAVAIL A CONSISTE A MESURER EXPERIMENTALEMENT LA CINETIQUE D'INCORPORATION DE COMPOSES GAZEUX A L'ETAT DE TRACES DANS LA PHASE AQUEUSE. LE PRINCIPE GENERAL DE CES MESURES CONSISTE A EXPOSER UNE PHASE LIQUIDE TRES DISPERSEE A UNE PHASE GAZEUSE CONTENANT LE GAZ EN TRACES A ETUDIER. PUIS DE SUIVRE L'EVOLUTION DE SA CONCENTRATION QUI EST APPARUE DANS LA PHASE AQUEUSE. LES DIFFERENTES ESPECES ETUDIEES SONT L'ACIDE CHLORHYDRIQUE, LE PENTOXYDE D'AZOTE, L'ACIDE NITREUX, LE CHLORURE D'ACIDE TRICHLOROACETIQUE, LE CHLORURE D'ACIDE TRIFLUOROACETIQUE, LE FLUORURE D'ACIDE TRIFLUOROACETIQUE ET LE FLUORURE DE CARBONYLE. CES ETUDES ONT ETE MENEES EN FONCTION DE DIVERS PARAMETRES TELS QUE LA TEMPERATURE, LA DUREE D'EXPOSITION, LA PRESSION, LA COMPOSITION DE LA PHASE AQUEUSE ET ONT PERMIS D'ACCEDER DIRECTEMENT A LA CINETIQUE DU TRANSFERT DE MASSE INTERFACIAL. IL A EGALEMENT ETE POSSIBLE DANS CERTAINS CAS D'ESTIMER LES VALEURS DE CERTAINES PROPRIETES PHYSICO-CHIMIQUES TELLES QUE LES CONSTANTES DE HENRY ET LES CONSTANTES CINETIQUES D'HYDROLYSE. FINALEMENT, UN MODELE NUMERIQUE PERMETTANT DE SIMULER L'OXYDATION DU SOUFRE IV EN SOUFRE VI EST PRESENTE. CELUI-CI PREND EN COMPTE AUSSI BIEN LES DIFFERENTS PHENOMENES DE TRANSPORT QUE LES CINETIQUES CHIMIQUES ET PERMET DE MONTRER LEUR COUPLAGE

Download or read book Heterogeneous Atmospheric Chemistry written by David R. Schryer and published by American Geophysical Union. This book was released on 1982 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 26. In the past few years it has become increasingly clear that heterogeneous, or multiphase, processes play an important role in the atmosphere. Unfortunately the literature on the subject, although now fairly extensive, is still rather dispersed. Furthermore, much of the expertise regarding heterogeneous processes lies in fields not directly related to atmospheric science. Therefore, it seemed desirable to bring together for an exchange of ideas, information, and methodologies the various atmospheric scientists who are actively studying heterogeneous processes as well as other researchers studying similar processes in the context of other fields.

Download or read book Progress and Problems in Atmospheric Chemistry written by John Roger Barker and published by World Scientific Publishing Company Incorporated. This book was released on 1995 with total page 941 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric chemistry is central to understanding global changes — ozone depletion, appearance of the polar ozone holes, and compositional changes which worsen the greenhouse effect. Because of its importance, work is progressing on many fronts.This volume emphasizes the troposhere and stratosphere and has chapters on gas phase, condensed phase, and heterogeneous chemistry. Present progress is emphasized, and important future directions are also described.This book fills a need not satisfied by any others and will be popular for some years to come. It informs students and newcomers to the field of the many facets of atmospheric chemistry and can be used as a text for advanced students. It is also a valuable desk reference summarizing activities by quite a number of the most active research groups.Chapter 18 by Kolb et al. on heterogeneous chemistry is especially noteworthy because it represents a unique joint effort by several groups working on a very timely subject; they describe a conceptual framework and establish conventions which will be standard in future papers on this subject.

This book was released on 2006-09-19 with total page 1071 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of Studies in Surface Science and Catalysis contains the Proceedings of the 9th International Symposium on the Scientific Bases for the Preparation of Heterogeneous Catalysts, held on the campus of the "Universit catholique de Louvain" (UCL) in Louvain-la-Neuve, Belgium, on September 10-14, 2006. This series of symposia was initiated in 1975 on a regular 4-year interval basis. The Symposium covered the following topics: key aspects in catalysts preparation, micro- and mesoporous supports, supported metal catalysts, structured catalysts, tailored zeolites, catalysis by bases, and catalysts for fuel production. These topics served as guidelines for the sessions both in the programs of oral communications (41 contributions including 7 keynote communications – one for each topic) and poster presentations (101 contributions). In addition, the opening invited lecture addressed the question of scaling-up high-throughput experimental approaches.* Contains a collection of the papers presented at the workshop

Download or read book Biominerals written by F.C.M. Driessens and published by CRC Press. This book was released on 1990-09-26 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive analysis of biominerals, in particular phosphates and carbonates of calcium. The book begins with a discussion of the theories of solid state chemistry and thermodynamics of ionic solid solutions and applies these theories to show how physiological constituents like sodium, magnesium, carbonate, chloride, fluoride, lead, or strontium influence the formation, stability, and solubility of calcium phosphates. The results of this discussion are then applied to a critical evaluation of data regarding minerals in bone, dentin, and tooth enamel, their formation during growth and turn-over, their stability under physiological conditions and their breakdown under pathological conditions. These principles are also applied to pathological calcifications such as renal calculi, arterial wall calcifications, chondrocalcinosis, dental calculus and salivary stones. A similar approach is used as the authors discuss carbonations such as calcite, dolomite, and aragonite. The book also includes an extensive analysis of the advantageous effects of magnesium supplementation. The wealth of knowledge in this extensive treatise of biominerals is valuable to medical, dental and ecological biologists, as well as scientists and clinicians in the fields of osteoporosis, bone diseases, caries, renal stone disease, parodontology and nutrition.
