  1. 11. Surface Plasmon Resonance : Sensitivity and Resolution

    Författare :Knut Johansen; Günter Gauglitz; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Surface plasmon resonance (SPR) is a frequently used technique for detection of biomolecular interactions at surfaces. The SPR phenomenon emanates from an electromagnetic surface wave that is exited by a light source. LÄS MER

  3. 12. Tribology of stamping : the influence of designed steel sheet surface topography on friction

    Författare :Daniel Wiklund; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel sheet; tribology; surface topography; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Sammanfattning : Tribology is the science of friction, wear, and lubrication; the interaction of surfaces in relative motion. The tribological conditions in sheet metal forming influences the flow of material in forming operations, the strain distributions of sheet material, extent of wear, and thereby the quality of products.

  4. 13. Model-based Approaches to Diffuse Optical Imaging and Dosimetry

    Författare :Johan Axelsson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photodynamic therapy; diffuse light propagation; fluorescence; imaging; dosimetry; inverse problem;

    Sammanfattning : The work within this thesis investigates Photodynamic therapy and Fluorescence imaging for therapeutics and visualization of deeply embedded lesions. Photodynamic therapy (PDT) is a cancer treatment modality that can eradicate tumors when light, a photosensible drug and oxygen are present. LÄS MER

  5. 14. Laser Diagnostics and Chemical Modeling of Combustion and Catalytic Processes

    Författare :Michael Försth; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; catalysis; platinum; OH; elastic light scattering; planar LIF; fuel spray; surface reactions; imaging; Chemkin; hydroxyl; stagnation flow; gas-phase chemistry;

    Sammanfattning : The H2+1/2O2 H2O reaction on hot platinum surfaces has been studied. A stagnation flow geometry was used with a gas mixture of H2 and O2 at subatmospheric pressures. LÄS MER

  7. 15. Surface interactions and adsorbate structures : An atomic force microscopy study

    Författare :Goran Bogdanovic; KTH; []
    Nyckelord :atomic force microscope; AFM; cantilever calibration; colloidal probe; surface force; force curve; friciton; hydrophobic; adhesion; roughness; multilayer; silica; cellulose; cationic polyelectrolyte; MAPTAC;

    Sammanfattning : Atomic force microscopy, AFM, was used for studying somecurrent topics in the field of surface and colloid science. Themain topics addressed in this thesis were: the nature of thelong-range attraction between hydrophobic surfaces; slidingfriction behavior for microscopic contacts; and interfacialstructuring of polyelectrolyte-nanoparticle multilayerfilms.
