  1. 1. Sensory-motor regulation of human biting behavior

    Författare :Krister Svensson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In order to control oral motor behavior, such as biting and chewing, we rely on information provided by a variety of sense organs, including periodontal mechanoreceptors (PMRs). The PMRs, located among the collagen fibers in the periodontal ligament that attaches the root of the tooth to the alveolar bone, send signals to the central nervous system when the surrounding collagen fibers are stretched by loading of the tooth.

  3. 2. Adsorption of Molecular Hydrogen on Cu, Pd and Ni Surfaces

    Författare :Krister Svensson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron energy loss spectroscopy; nickel; molecular chemisorption; hydrogen; palladium; physisorption; photodesorption; copper;

    Sammanfattning : This thesis is devoted to spectroscopic studies of molecular hydrogen adsorbed on metal surfaces. Hydrogen is the simplest molecule available and is a very valuable model adsorbate. From a spectroscopic point of view there are also three easily accessible molecular isotopes, H2, HD and D2, with widely different masses. LÄS MER

  4. 3. Materials aspects in spin-coated films for polymer photovoltaics

    Författare :Ana Sofia Anselmo; Ellen Moons; Krister Svensson; Jan van Stam; Paul Dastoor; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; materials science; photovoltaics; conjugated polymer; polymer solar cell; bulk heterojunction; coating; morphology; fullerene; photostability; degradation; X-ray absorption spectroscopy; synchroton-based techniques; Materialvetenskap; Materialvetenskap;

    Sammanfattning : Polymer-based photovoltaics have the potential to contribute to boosting photovoltaic energy conversion overall. Besides allowing large-area inexpensive processing, polymeric materials have the added benefit of opening new market applications for photovoltaics due to their low-weight and interesting mechanical properties.

  5. 4. Memory Effects on Iron Oxide Filled Carbon Nanotubes

    Författare :Carlos Cava; Clas Persson; Lucimara Roman; Krister Svensson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Memory devices; Carbon Nanotubes; energy; nanotechnology; Iron Oxide;

    Sammanfattning : In this Licentiate Thesis, the properties and effects of iron and iron oxide filled carbon nanotube (Fe-CNT) memories are investigated using experimental characterization and quantum physical theoretical models. Memory devices based on the simple assembly of Fe-CNTs between two metallic contacts are presented as a possible application involving the resistive switching phenomena of this material. LÄS MER

  7. 5. The influence of crystallinity on the properties of carbon nanotubes

    Författare :Mattias Flygare; Krister Svensson; Thomas Wågberg; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; carbon nanotubes; crystallinity; electrical conductivity; transmission electron microscopy; Physics; Fysik;

    Sammanfattning : Carbon nanotubes have been advertised as a material with quite extraordinary properties, both mechanically and electrically. The truth is that carbon nanotubes is not one material, but several different. LÄS MER
