  1. 1. On Surface Topography of Cylinder Liners

    Författare :Zlate Dimkovski; John Westberg; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cylinder liner; Surface Roughness; Characterisation; Honing; Wear; Blechmantel; Groove Parameters; Quality Control; Flow Simulation; Surface engineering; Ytbehandlingsteknik;

    Sammanfattning : The frictional losses, oil consumption and emissions in internal combustion engines are in great extent controlled by the cylinder liner surface topography. This emphasises the importance of: investigating the liner’s topography by objectively characterising it, investigating its effects on the tribological function to gain a better understanding and improving its manufacturing.

  3. 2. Surfaces of Honed Cylinder Liners

    Författare :Zlate Dimkovski; B.-G. Rosén; Mohamed El-Mansori; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Honing; Characterisation; Blechmantel; Groove Parameters; Quality Control; Oil Consumption; Wear; Friction; Mixed Lubrication Simulation; Surface engineering; Ytbehandlingsteknik;

    Sammanfattning : Cylinder liner surfaces are often on the agenda of engine developers because of their large influence on the frictional losses, oil consumption and emissions of internal combustion engines. Improving the liner function involves not only manufacturing new surfaces and checking their function but also characterising them as a necessary intermediate step for better understanding of the changes made.

  4. 3. Detection of Biomolecules: Syntheses and Studies of Minor Groove Binding Unsymmetrical Cyanine Dyes and Chromogenic Enzyme Substrates

    Författare :Jonas Karlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palladium-catalysed cross-couplings; optical spectroscopy; minor groove binding; DNA; cyanine dye; enzyme; intercalation; fluorescence; chromogenic;

    Sammanfattning : Visualisation or detection of biomolecules is usually achieved by the use of fluorescent or highly coloured chromophores. The work presented in this thesis deals with the development of new chromogenic substrates for the detection of enzyme activity, and new DNA-binding fluorescent dyes for staining of DNA. LÄS MER

  5. 4. Molecular dynamics of protein-nucleic acid complexes

    Författare :Katarina Hart; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Nucleic acids are essential molecules when it comes to replication, transcription and translation of the genetic information and nearly all functions of nucleic acids are carried out in complex with proteins. The proteins need to be able to discriminate between different sites on the nucleic acids for correct binding. LÄS MER

  7. 5. Laser processing of Silica based glass

    Författare :Patrik Holmberg; Fredrik Laurell; Valerio Pruneri; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fiber Bragg Gratings; photosensitivity; Glass; laser machining; optical fibers; fiber sensor; Physics; Fysik;

    Sammanfattning : The main topic of this thesis work is photosensitivity and photo-structuring of optical fibers and bulk glass. Although research in the field of photosensitivity in glass and optical fibers has been ongoing for more than three decades, the underlying mechanisms are still not well understood. LÄS MER
