  1. 21. Mass Transport Through Polymer Films: The Importance of Interfaces and Compatibility

    Författare :Sofie Gårdebjer; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose; Barriers; Surface modification; Compatibility; Interfaces; Polymer films;

    Sammanfattning : Different types of barriers are used in packaging to keep and protect products from the surrounding environment and are often essential for storing and transportation. Today, many barriers are made of different types of polymers, but since most polymers do not exhibit desired barrier properties on their own, combinations must be used. LÄS MER

  3. 22. Interfaces in Dye-Sensitized Solar Cells Studied with Photoelectron Spectroscopy at Elevated Pressures

    Författare :Susanna Kaufmann Eriksson; Anders Hagfeldt; Håkan Rensmo; Erik Johansson; Joachim Schnadt; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dye-sensitized solar cells; interfaces; solvation; photoelectron spectroscopy; HPXPS; HP-HAXPES; liquid jet; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Sammanfattning : With an increasing demand for renewable energy sources, research efforts on different solar cell technologies are increasing rapidly. The dye-sensitized solar cell (DSC) is one such technology, taking advantage of light absorption in dye molecules. LÄS MER

  4. 23. Crystalline cellulose in bulk and at interfaces as studied by atomistic computer simulations

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cellulose; molecular dynamics simulation; interfaces; Chemistry; Kemi;

    Sammanfattning : Cellulose is a linear polysaccharide, serving as reinforcement in plant cell walls.Understanding its structure and properties is of importance in the developmentof nanostructured cellulose materials. LÄS MER

  5. 24. Topographical Impact on Space Charge Injection, Accumulation and Breakdown in Polymeric HVDC Cable Interfaces

    Författare :Espen Doedens; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; interfaces; XLPE; roughness; cable peelings; polymer surfaces; space charge; field enhancement factor; PEA; DC breakdown; extruded cable; roughness enhanced charge injection; HVDC; charge injection;

    Sammanfattning : Extruded HVDC cable systems feature a variety of interface types, for which physio-chemical properties will depend on the type of application. Such applications can be joints, terminations or the cable itself, all introducing different material combinations and manufacturing methods. LÄS MER

  7. 25. On the adsorption behaviour of saliva and purified salivary proteins at solid/liquid interfaces

    Författare :Liselott Lindh; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acidic proline-rich proteins; adsorption; BSM; diffusion; ellipsometry; interfaces; mass transport limitation; mucins; MUC5B; saliva; salivary proteins; statherin; surface properties;

    Sammanfattning : Den salivfilm som bildas genom selektiv proteinadsorption på ytor i munhålan har stor profylaktisk betydelse genom sin skyddande funktion och befrämjar därigenom oral hälsa. Några av de adsorberade komponenterna har smörjande funktion (t ex muciner, sura prolinrika proteiner (PRP) och statherin), som är viktig bl a för att förhindra slitage mellan tandytor vid tuggning och hos gnisslare.
