  5. 3. Latex Colloid Dynamics in Complex Dispersions : Fluorescence Microscopy Applied to Coating Color Model Systems

    Author : Gunilla Carlsson; Jan van Stam; Maria da Graca Miguel; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluorescence microscopy; coating color; colloid; latex; diffusion; Brownian motion; film formation; polymer interaction; Physical chemistry; Fysikalisk kemi; Kemi; Chemistry;

    Abstract : Coating colors are applied to the base paper in order to maximize the performance of the end product. Coating colors are complex colloidal systems, mainly consisting of water, binders, and pigments. To understand the behavior of colloidal suspensions, an understanding of the interactions between its components is essential.. READ MORE

  6. 4. Effect of solvents during material treatment applications : tuning hydrophilicity of silicone rubber and drug loading in mesoporous silica

    Author : Anna Hillerström; Jan van Stam; Lennart Piculell; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solvents; liquid carbon dioxide; Interpenetrating Polymer Network IPN ; silicone rubber; hydrophilic; phase domains; mesoporous silica; ibuprofen; adsorption isotherms; release; Kemi; Chemistry;

    Abstract : Choosing the right solvent is critical for many industrial applications. A useful property for selection of solvents is their solubility parameters. This concept of solubility parameters is central to this thesis and has been used in two different case studies of material treatment applications. READ MORE

  7. 5. Film morphology for organic solar cells : Effect of Solubility and Gravity Conditions

    Author : Ishita Jalan; Jan van Stam; Leif Ericsson; Stela Andrea Muntean; Philippe Leclère; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; Chemistry - Physical Chemistry; Kemi - fysikalisk kemi;

    Abstract : Organic photovoltaics is a promising environmentally friendly technology, due to their printability, light-weight nature and mechanical flexibility, and the possibility to use off-grid. Research and development in this field has resulted in power conversion efficiencies of over 15%. READ MORE
