Book excerpt: LES PROPRIETES STRUCTURANTES DES MESOPHASES DE TYPE CRISTAL LIQUIDE LYOTROPE SONT ASSOCIEES AUX AVANTAGES DU PROCEDE SOL-GEL POUR LA FORMATION DE COUCHES MINCES CONTINUES DE SILICE. LA SYNTHESE DE MATERIAUX INORGANIQUES A TEXTURE POREUSE ORDONNEE PEUT AINSI ETRE OBTENUE PAR EFFET D'EMPREINTE APRES ELIMINATION DE LA MESOPHASE STRUCTURANTE. L'APPLICATION A L'ELABORATION DE MEMBRANES CERAMIQUES DOIT AINSI PERMETTRE UNE AMELIORATION DE LA PERMSELECTIVITE DES COUCHES SEPARATIVES, LIEE A LA MONODISPERSITE EN TAILLE DES PORES. LE CHOIX DES MOLECULES AMPHIPHILES STRUCTURANTES REND DE PLUS POSSIBLE L'AJUSTEMENT DE LA TAILLE DES PORES DE LA MEMBRANE. LES COUCHES A STRUCTURE HEXAGONALE SYNTHETISEES A L'AIDE DE TENSIOACTIFS DE TYPE ALKYLTRIMETHYLAMMONIUM SONT PLUS PARTICULIEREMENT ETUDIEES. IL EST EN NOTAMMENT MONTRE QUE LES CONDITIONS DE SYNTHESE PEUVENT ETRE DEFINIES A PARTIR DES DIAGRAMMES DE PHASE EAU TENSIOACTIF CORRESPONDANTS. LES RESULTATS SONT GENERALISES A D'AUTRES STRUCTURES ET D'AUTRES TYPES DE STRUCTURANTS. LA CARACTERISATION DES MATERIAUX PAR DIFFRACTION DES RAYONS X EN 1D OU 2D AINSI QUE LA MICROSCOPIE ELECTRONIQUE A TRANSMISSION METTENT EN EVIDENCE LA TEXTURATION DE LA COUCHE ET LE FAIT QUE LA STRUCTURE REELLE DES FILMS, APRES SECHAGE ET CALCINATION, N'EST PAS HEXAGONALE MAIS DE TYPE RECTANGLE CENTREE. LA STRUCTURE S'ORIENTE PARALLELEMENT AU SUBSTRAT, CE QUI EST NEFASTE POUR LA PERMEABILITE DES COUCHES POREUSES PRODUITES. POUR MODIFIER CETTE ANISOTROPIE, DES PARTICULES COLLOIDALES SONT INTRODUITES DANS LE MILIEU : DES COLLOIDES DE SILICE OU DES COLLOIDES MAGNETIQUES DE MAGHEMITE. CES DERNIERS SONT UTILISES AFIN D'EVALUER L'EFFET DE LEUR ROTATION SOUS CHAMP MAGNETIQUE SUR L'ORIENTATION DES CYLINDRES MICELLAIRES FORMANT LA MESOPHASE. LES INTERACTIONS ENTRE LES COLLOIDES INTRODUITS ET LES AUTRES CONSTITUANTS DU MILIEU REACTIONNEL SONT D'ABORD ETUDIEES. L'INFLUENCE DE L'ENSEMENCEMENT SUR LA TEXTURE ET LA PERMEABILITE DE COUCHES POREUSES EST ENSUITE EVALUEE.

Book excerpt: DURANT CES DERNIERES ANNEES, LE DEVELOPPEMENT DES COMPOSES III-V TELS QUE L'ARSENIURE DE GALLIUM OU LE PHOSPHURE D'INDIUM FUT SPECTACULAIRE. CES COMPOSES SONT TRES INTERESSANTS POUR LES APPLICATIONS MICRO-ELECTRONIQUES ET OPTOELECTRONIQUES. OR LES CARACTERISTIQUES DE CES MATERIAUX ET DES COMPOSANTS REALISES SONT TRES SENSIBLES A LEUR ETAT DE SURFACE ET D'INTERFACE. IL EST DEVENU ESSENTIEL DE COMPRENDRE LES MECANISMES DE FORMATIONS DES STRUCTURES POUR MAITRISER AU MIEUX LA TECHNOLOGIE DES COMPOSANTS REALISES. PLUS RECEMMENT, UN NOUVEAU MATERIAU LE SILICIUM POREUX EST APPARU COMME ETANT TRES PROMETTEUR DANS LE DOMAINE DE L'OPTOELECTRONIQUE. CELUI-CI A FAIT RECEMMENT L'OBJET DE NOMBREUSES RECHERCHES COMPTE TENU DE SES PROPRIETES LUMINESCENTES DONT L'ORIGINE EST ENCORE DISCUTEE. CES PROPRIETES SEMBLENT DEPENDRE BEAUCOUP DES ETATS DE SURFACE ET D'INTERFACE. LA PREMIERE PARTIE DE CE MEMOIRE EST CONSACRE A LA CARACTERISATION DE LA SURFACE ET DE LA CONCENTRATION EN HYDROGENE D'UN SUBSTRAT DE SILICIUM POREUX. LA SPECTROSCOPIE DES ELECTRONS RETRODIFFUSES ELASTIQUEMENT (EPES) S'EST AVEREE TRES PERFORMANTE. CETTE METHODE NOUS A PERMIS DE CALCULER LE COEFFICIENT DE REFLEXION ELASTIQUE POUR DIFFERENTES POROSITES. NOUS AVONS PU METTRE EN EVIDENCE UN CHANGEMENT DE MORPHOLOGIE DES COUCHES POREUSES LORS DE L'AUGMENTATION DE LA POROSITE. LA DEUXIEME PARTIE DE CE TRAVAIL ENTRE DANS LE CADRE DES ETUDES CONSACREES A LA REALISATION DE STRUCTURES MIS (METAL/ISOLANT/SEMI-CONDUCTEUR). NOUS NOUS SOMMES ATTACHEES PLUS PARTICULIEREMENT A L'ETUDE DE L'INTERFACE ISOLANT/SEMI-CONDUCTEUR. AFIN DE REALISER DE TELLES STRUCTURES, NOUS AVONS PROCEDE DANS UN PREMIER TEMPS A LA REALISATION DE COUCHES MINCES D'ALUMINE SUR DES SUBSTRATS DE SILICIUM (100). EN EFFET, UNE BONNE REPRODUCTIBILITE ET UN CONTROLE DES PARAMETRES D'ELABORATION DE L'ISOLANT SONT EXIGES POUR ABOUTIR A L'AMELIORATION PROGRESSIVE DE LA QUALITE DES COMPOSANTS REALISES. DANS UN SECOND TEMPS DES DEPOTS D'ALUMINE ONT ETE REALISES SUR DES SUBSTRATS DE PHOSPHURE D'INDIUM (100). EN NOUS APPUYANT SUR DES TRAVAUX ANTERIEURS FAITS AU LABORATOIRE LASMEA SUR LA STABILISATION DES SURFACES D'INP(100) PAR DES ATOMES D'ANTIMOINE, NOUS AVONS EFFECTUE DES ETUDES PHYSICO-CHIMIQUES ET ELECTRIQUES DES STRUCTURES DU TYPE HG/AL#2O#3/INP ET HG/AL#2O#3/INSB/INP. NOUS AVONS MIS EN EVIDENCE, L'AMELIORATION SENSIBLE DE LA QUALITE DE L'ISOLANT LORS D'UNE RESTRUCTURATION DE LA SURFACE D'INP PAR DES ATOMES D'ANTIMOINE, UNE REDUCTION DE LA MIGRATION DES ELEMENTS DU SEMI-CONDUCTEUR ETANT OBSERVEE. NOUS AVONS PU CORRELER L'HISTORIQUE DE LA FORMATION DES STRUCTURES A LA MESURE ELECTRIQUE FINALE, CE QUI EST PARTICULIEREMENT IMPORTANT DANS LA COMPREHENSION DES PHENOMENES SE PRODUISANT AUX INTERFACES

This book was released on 2013-11-27 with total page 0 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 Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.

Download or read book Fundamentals of Latex Film Formation written by Joseph Keddie and published by Springer Science & Business Media. This book was released on 2010-02-18 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has emerged out of our long-time research interests on the topic of latex film formation. Over the years we have built up a repertoire of slides used in conference presentations, short courses and tutorials on the topic. The story presented in this book has thereby taken shape as it has been told and re-told to a mix of academic and industrial audiences. The book presents a wide body of work accumulated by the polymer colloids community over the past five decades, but the selection of examples has been flavoured by our particular experimental interests and development of mathematical models. We intend the book to be a starting point for academic and industrial scientists beginning research on latex film formation. The emphasis is on fundam- tal mechanisms, however, and not on applications nor on specific effects of formu- tions. We hope that the book consolidates the understanding that has been achieved to-date in the literature in a more comprehensive way than is possible in a review article. We trust that the reader will appreciate the fascination of the topic.

This book was released on 2005-06-30 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a self-contained introduction to cellular automata and lattice Boltzmann techniques. Beginning with a chapter introducing the basic concepts of this developing field, a second chapter describes methods used in cellular automata modeling. Following chapters discuss the statistical mechanics of lattice gases, diffusion phenomena, reaction-diffusion processes and non-equilibrium phase transitions. A final chapter looks at other models and applications, such as wave propagation and multiparticle fluids. With a pedagogic approach, the volume focuses on the use of cellular automata in the framework of equilibrium and non-equilibrium statistical physics. It also emphasises application-oriented problems such as fluid dynamics and pattern formation. The book contains many examples and problems. A glossary and a detailed bibliography are also included. This will be a valuable book for graduate students and researchers working in statistical physics, solid state physics, chemical physics and computer science.
