  1. 1. Studies on Polarised Light Spectroscopy

    Författare :Max Bergkvist; Simon Farnebo; Erik Tesselaar; Folke Sjöberg; Johan Thorfinn; Knut Kvernebo; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis project focuses on measurements of dermal microcirculation during vascular provocations with polarised light spectroscopy. This is done with a non-invasive method commercially available as Tissue viability imaging (TiVi) which measures concentration and oxygenation of red blood cells in the papillary dermis. LÄS MER

  4. 3. Ultrastructural Aspects of Pulp Fibers as Studied by Dynamic FT-IR Spectroscopy

    Författare :Margaretha Åkerholm; KTH; []
    Nyckelord :cellulose; cooperation; crystallinity; dynamic test; glucomannan; hardwood; holocellulose; humidity; infrared spectroscopy; kraft pulp; lignin; mechanical pulp; orientation; polarised light; softwood; strain; sulphite pulp; viscoelasticity; xylan;

    Sammanfattning : Dynamic (or 2D) FT-IR spectroscopy in combination withpolarized IR irradiation has been used in this work to studywood polymer orientation and interactions on theultrastructural level in wood fibers in the native state aswell as the effects of different pulping processes. The woodpolymer interactions were studied under both dry and humidconditions. LÄS MER

  5. 4. Self-assembly Strategies for Functional DNA Nanostructures

    Författare :John Tumpane; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbon nanotube; polarised spectroscopy; nanotechnology; self-assembly; orientation; lipid membrane; gel electrophoresis; DNA;

    Sammanfattning : The technological revolution of the twentieth century was famously subject to Moore’s law which related the rate of growth to the ability to scale-down the size of the components – size matters. Several decades later we are, however, approaching the limit of what is possible with silicon wafers. LÄS MER

  7. 5. Functional materials studies by Mössbauer spectroscopy

    Författare :Erik Nordström; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Physics; Fysik; fysik; Physics;

    Sammanfattning : Mössbauer spectroscopy has been used as a powerful tool to investigate the local properties of some materials suitable as active ingredients in technological applications. The magnetic properties of some magnetic multilayers were investigated using conversion electron Mössbauer spectroscopy. LÄS MER
