Book Synopsis Surfaces and Interfaces of Liquid Crystals by : Theo Rasing
Download or read book Surfaces and Interfaces of Liquid Crystals written by Theo Rasing and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the state of the art of our understanding of liquid-crystal interfaces on a molecular level. The interactions of liquid crystal molecules with a surface play an essential role in the operation of liquid crystal displays (LCD's) and other LC devices that are based on the controllable anchoring of LC molecules on polymer coated surfaces. This book addresses the microscopic interaction between a macromolecule (liquid crystal, polymer) and a wall, using state of the art surface and interface-sensitive experimental techniques, such as Atomic Force Microscopy (AFM), Scanning Tunneling Microscopy (STM), Linear and Nonlinear Optical Microscopy and (Dynamic) Light Scattering (DLS). These experimental techniques were complemented with computer simulations and supra molecular chemistry methods to develop controllable polymeric surfaces.

This book was released on 2022-10-27 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the fabrication of orientation-controlled colloidal quantum well (nanoplatelet) thin films using liquid interface self-assembly. The book details methods for orientation-controlled deposition of CdSe core nanoplatelets for characterization of directional energy transfer in nanoplatelets and layer-by-layer construction of CdSe/CdZnS core/shell nanoplatelets to create optically active waveguides with precisely tunable thickness and excellent uniformity across device scale. It also provides a future outlook for construction of large-scale two- and three-dimensional nanoplatelet superstructures and their incorporation into device fabrication.

Book Synopsis Small spatial scales in wetting on non-structured and structured surfaces by : Céline J. E. Richard
Download or read book Small spatial scales in wetting on non-structured and structured surfaces written by Céline J. E. Richard and published by . This book was released on 2011 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: A une époque où la miniaturisation est l'un des principaux défis de la science, la physique du mouillage aux petites échelles est loin d'être complètement comprise. Le rôle structurant des interfaces, les hétérogénéités du substrat ou l'occurrence d'effets dits de ligne commencent à se faire sentir. Le but de la présente thèse, expérimentale, est d'apporter de nouveaux indices permettant le développement des analyses théoriques. Deux systèmes à petite échelle et complexes ont été étudiés: les films minces de cristaux liquides sur substrat liquide et les précurseurs de liquides ioniques sur substrats solides. La description des propriétés de mouillage des cristaux liquides nématiques nécessite deux ingrédients s'ajoutant à ceux des liquides usuels : l'élasticité, qui est source d'interactions à longue portée et l'ancrage qui décrit le rôle spécifique joué par les conditions aux limites. Sur un substrat liquide, les films minces nématiques avec des conditions d'ancrage antagonistes montrent des structures complexes ainsi qu'une coexistence d'épaisseurs. Différents systèmes ont été étudiés au microscope optique dans la gamme de température nématique et aux alentours de la transition nématique / isotrope. Les résultats ont été comparés aux modèles disponibles qui sont basés sur une théorie continue de l'élasticité nématique. Les liquides ioniques sont des sels surfondus à température ambiante. Ils sont devenus omniprésents dans l'industrie, ce qui explique que la compréhension de leur mouillage soit un sujet brûlant. De faibles quantités de liquides ioniques ont été déposées sur différents substrats, lisses ou rugueux. Le paysage que l'on obtient, gouttelettes et films minces, a été imagé par AFM (Atomic Force Microscopy). Les résultats ont été comparés aux modèles disponibles pour les films minces et les gouttes nanoscopiques

Book Synopsis Freely Suspended Liquid Crystalline Films by : A. A. Sonin
Download or read book Freely Suspended Liquid Crystalline Films written by A. A. Sonin and published by John Wiley & Sons. This book was released on 1998 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freely Suspended Liquid Crystalline Films Andrei A. Sonin Centre d'Etudes Atomiques de Saclay, France and Institute of Crystallography, Russian Academy of Sciences with a Foreword by Professor Noel Clark University of Colorado, USA This book provides a brief introduction to the physics of liquid crystals and to macroscopic physical parameters characterising freely suspended liquid crystalline (FSLC) films, and then reviews the experimental techniques for preparing these films, measuring their thicknesses, and investigating their physical properties and structural aspects. Molecular structures and defects of FSLC films and the problems of film stability, thinning and rupture are discussed in later chapters. Physical phenomena, such as orientational and phase transitions, Frederick's and flexoelectric effects, hydroelectrodynamics, etc., are also analysed. Finally, some applications of FSLC films in industry and in various branches of science are discussed. Specialists working in the physics of liquid crystals and in surface physics will find this book of interest. Industrial firms and their research centres investigating liquid crystals, biological membranes, detergent/surfactant/biomedical areas; and graduates and postgraduates in solid state physics and crystallography will also benefit from this book. The book has an easy-to-read style with just the minimum amount of mathematics necessary to explain important concepts. This is the first book dedicated exclusively to the physics of FSLC in almost a century since their discovery and last twenty years of their active studies. Andrei Sonin, a scientist in the area of FSLC and author of many articles on surface phenomena in liquid crystals, the properties and behaviour of thin liquid crystalline and surfactant films, has a long standing reputation in liquid crystals and surfactant systems and has been particularly active in issues involving surface interactions.

Book Synopsis Soft Matter Physics by : Mohamed Daoud
Download or read book Soft Matter Physics written by Mohamed Daoud and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a liquid crystal watch, the molecules contained within a thin film of the screen are reorientated each second by extremely weak electrical signals. Here is a fine example of soft matter: molecular systems giving a strong response to a very weak command signal. They can be found almost everywhere. Soft magnetic materials used in transformers exhibit a strong magnetic moment under the action of a weak magnetic field. Take a completely different domain: gelatin, formed from col lagen fibres dissolved in hot water. When we cool below 37°C, gelation occurs, the chains joining up at various points to form a loose and highly deformable network. This is a natural example of soft matter. Going further, rather than consider a whole network, we could take a single chain of flexible polymer, such as polyoxyethylene [POE = (CH CH O)N, 2 2 5 where N rv 10 ], for example, in water. Such a chain is fragile and may break under flow. Even though hydrodynamic forces are very weak on the molecular scale, their cumulated effect may be significant. Think of a rope pulled from both ends by two groups of children. Even if each girl and boy cannot pull very hard, the rope can be broken when there are enough children pulling.

PAR CONSEQUENT, UNE ORGANISATION MOLECULAIRE SPECIFIQUE DU CRISTAL LIQUIDE AU VOISINAGE D'UNE INTERFACE AFFECTE LE COMPORTEMENT DU CRISTAL LIQUIDE A DES ECHELLES MACROSCOPIQUES, OBSERVABLES A L'IL NU. IL EN VA AINSI DES PROPRIETES DE MOUILLAGE DES CRISTAUX LIQUIDES SUR UNE SURFACE SOLIDE. NOUS OBSERVONS QUE LA PHASE NEMATIQUE DU COMPOSE 5CB (4-N-PENTYL-4-CYANOBIPHENYLE) MOUILLE COMPLETEMENT LA SURFACE SOLIDE D'UNE PASTILLE DE SILICIUM ALORS QUE LA PHASE ISOTROPE NE MOUILLE CES SUBSTRATS QUE PARTIELLEMENT.
