  1. 1. Shear Fracture and Delamination in Packaging Materials : A study of Experimental Methods and Simulation Techniques

    Författare :Md. Shafiqul Islam; Sharon Kao-Walter; Christian Johansson; Johan Tryding; Blekinge Institute of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Package opening; Shear test specimen; Stress intensity factor; Finite Element simulation; Scanning electron microscopy; Polymers; Interlaminar shear delamination;

    Sammanfattning : Packages are the means of preservation, distribution and convenience of use for food, medicine and other consumer products. Package opening is becoming complicated in many cases because of cutting cost in design and production of opening techniques. LÄS MER

  4. 3. Materials Reliability in PEM Fuel Cells

    Författare :Live Mølmen; Peter Leisner; Ulf Jansson; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel cell; PEMFC; Bipolar plate; Catalyst; Electrodeposition; Corrosion; Stainless steel; Accelerated stress tests; bränsleceller; PEM; bipolära plattor; katalysator; elektroplätering; korrosion; accelererad testning;

    Sammanfattning : As part of the global work towards reducing CO2 emissions, all vehicles needs to be electrified, or fueled by green fuels. Batteries have already revolutionised the car market, but fuel cells are believed to be a key energy conversion system to be able to electrify also heavy duty vehicles. LÄS MER

  5. 4. On the influence of Si on anodising and mechanical properties of cast aluminium alloys

    Författare :Baiwei Zhu; Caterina Zanella; Salem Seifeddine; Peter Leisner; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Al-Si based casting alloys; anodising; corrosion protection; mechanical properties; Al-Si-baserade gjutningslegeringar; anodisering; korrosionsskydd; mekaniska egenskaper;

    Sammanfattning : The combination of two cost-effective processes, i.e. casting and anodising, would be an interest for the aluminium component applications. However, there are some obstacles in the application of anodising on cast Al alloys. LÄS MER

  7. 5. Cell-protein-material Interactions on Bioceramics and Model Surfaces

    Författare :Åsa Rosengren; Sven Oscarsson; Lucy Di Silvio; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; protein adsorption; blood proteins; biomaterials; ceramics; glass-ceramics; two-dimensional gel electrophoresis; protein orientation; silicon wafers; atomic force microscopy; bone cell adhesion; divalent cation dependency; Kemi; Chemistry; Kemi;

    Sammanfattning : The objective of this thesis was to investigate and characterize the interaction between blood proteins and different surfaces with emphasis on protein adsorption to bioceramics and model surfaces. Special effort was made to monitor the spontaneous and selective adsorption of proteins from human plasma and to examine the orientation, conformation and functional behavior of single proteins after adsorption.
