  1. 16. Numerical simulation of non-Newtonian fluids flow over surfaces

    Författare :Kazem Bazesefidpar; Outi Tammisola; Luca Brandt; Shahriar Afkhami; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic wetting; viscoelasticity; non-Newtonian fluids; contact- angle hysteresis; droplet spreading; self-propelled jumping; dynamisk vätning; viskoelasticitet; icke-Newtonska vätskor; kontaktlinjehysteres; dropparnas spridning på ytor; spontan hoppning av droppar från ytor; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Wetting of surfaces by droplets of non-Newtonian fluids is important for various industrial and natural processes such as coating and cleaning of surfaces and inkjet printing, to name a few. Viscoelastic fluids are compounds of a very small amount of polymers and solvent. LÄS MER

  3. 17. Carbon based Thin Films Prepared by HiPIMS and DCMS

    Författare :Susann Schmidt; Lars Hultman; Grzegorz Greczynski; Jörg Neidhardt; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The present thesis focuses on carbon based thin films prepared by high power impulse magnetron sputtering (HiPIMS) and direct current magnetron sputtering (DCMS). The properties of such thin films can be tailored to an extensive variety; the film microstructure, for example, ranges in the presented work from fully amorphous, graphitic films to fullerene like (FL).

    Sammanfattning : This thesis introduces new ways to produce micro-and nanostructures of recombinant spider silk and explores ways to characterize their topography, mechanical properties, cell compatibility, and permeability. The suitability of the formed structures for applications within tissue engineering, primarily in vitro tissue modeling, is also investigated. LÄS MER
