  1. 1. Relating the Bulk and Interface Structure of Hyaluronan to Physical Properties of Future Biomaterials

    Author : Ida Berts; Jöns Hilborn; Adrian R Rennie; Giovanna Fragneto; John W White; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hyaluronan; structure; bulk; interface; small-angle neutron scattering; neutron reflection; hydrogel; grafting; nanoparticles; protein interactions;

    Abstract : This dissertation describes a structural investigation of hyaluronan (HA) with neutron scattering techniques. HA is a natural biopolymer and one of the major components of the extracellular matrix, synovial fluid, and vitreous humor. READ MORE

  2. 2. An in situ spectro-electrochemical study of aluminium/polymer interfaces : development of ATR-FTIR and its integration with EIS for corrosion studies

    Author : Maria Öhman; Christofer Leygraf; Jan-Olov Nilsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; : ATR-FTIR; EIS; spectro-electrochemical; interface; aluminium; polymer; Other chemistry; Övrig kemi;

    Abstract : In order to extend the applications of aluminium, organic coatings may be applied on sheet materials, for instance for corrosion protection or aesthetic surface finish purposes in the automotive and construction industries, or on foil materials in the flexible packaging industry. The most common mechanisms for deterioration and structural failure of organically coated aluminium structures are triggered by exposures to the surrounding environment. READ MORE

  3. 3. Optical modelling of conjugated polymers : from materials to devices

    Author : Nils-Krister Persson; Andy Monkman; Linköpings universitet; []
    Keywords : Spectroscopic ellipsomctry; optical modelling; organic solar cell; conjugated polymer; polyfluorene; polythiophene; copolymer; fullerene blend; photovoltaic device; dielectric function; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Measurements and modelling of theoretical properties of polymer-based photovoltaic devices, PPVDs, are the subjects of this thesis. Modelling refers both to modelling of materials, based on extraction of the dielectric function, and to modelling of devices by computer simulation of the optical electrical field inside PPVDs.

  4. 4. Electrochromic Plasmonic Metasurfaces for Reflective Displays

    Author : Kunli Xiong; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Plasmonic; Keywords: Colorful electronic paper; Conductive polymer.;

    Abstract : Plasmonic nanomaterials provide brilliant colors that arise from the ambient light coupling to the free electrons in metals. In the Roman empire, noble metal nanoparticles were used for staining glass in Church windows and tableware. READ MORE

  5. 5. Development of ATR-FTIR Kretschmann Spectroscopy for In situ Studies of Metal / Polymer Interfaces : and its Intergration with EIS for Exposure to Corrosive Conditions

    Author : Maria Öhman; Christofer Leygraf; Herman Terryn; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

    Abstract : The environmental stability of a metal / polymer interface is essential for the durability and mechanical stability of constructions in several important areas such as the automotive, offshore, building and aerospace industries. The protective capability of a polymer film is strongly connected to its barrier properties, but the transport of water and corrosive constituents through the polymer and the subsequent processes at the metal surface are complicated to analyse in detail.
