    Sammanfattning : Corrosion protection is commonly achieved by applying a thin polymer coating on metal surfaces. In this doctoral thesis, a waterborne hydroxyacrylate-melamine copolymer coating was used for this purpose. The first step was to find the optimal curing conditions. LÄS MER

  4. 8. Relaxation and nanomechanical studies of the vickers residual stress field in glass

    Författare :Kwadwo O. Kese; Bill Bergman; Sture Hogmak; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; soda-lime glass; vickers residual stress field; nanoindentation; stress rekaxatuib; cube corner indenter; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The Vickers residual stress field (VRSF) in soda-lime glass results from the elastic-plastic contact event that takes place when a Vickers diamond pyramid is loaded onto the surface of the material in an indentation cycle. The importance of elastic-plastic indentation lies in the contact damage that it gives rise to in the surface of the glass. LÄS MER

  7. 10. Covalent Graphene Functionalization for the Modification of Its Physical Properties

    Författare :Hu Li; Klaus Leifer; Annick Loiseau; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; graphene; functionalization; nanomechanical property; graphene nanoscroll;

    Sammanfattning : Graphene, a two dimensional monolayer carbon sheet with the atoms tightly packed in a hexagonal lattice, has exhibited so many excellent properties, which enable graphene to break several material records with regard to carrier mobility, strength yield and thermal conductivity to name a few. Therefore, graphene has been placed as a potential candidate to allow truly next-generation material. LÄS MER
