  3. 2. Microstructure aspects of transition metal carbide thin films

    Författare :Jun Lu; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; vapour deposition; transition metal carbide; nanocrystallinity; epitaxy; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Transition metal carbides are important refractory materials used in many thin film applications. In this thesis, several transition metal carbides have been deposited using different chemical vapour deposition (CVD) and evaporation processes. In particular, the phase composition and microstructure of these carbide films have been studied. LÄS MER

  4. 3. Correlations in multiparticle production

    Författare :Markus Ringnér; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; String fragmentation; QCD; Correlations; Colour interference; Bose-Einstein interference; quantum mechanics; classical mechanics; Mathematical and general theoretical physics; relativity; gravitation; statistical physics; Matematisk och allmän teoretisk fysik; High energy interactions; thermodynamics; kvantmekanik; klassisk mekanik; termodynamik; cosmic rays; Kosmisk strålning; högenergi; statistisk fysik; relativitet; Fysicumarkivet A:1998:Ringnér;

    Sammanfattning : Different aspects of the strong interaction in particle collisions are studied. Most of the work is based on the Lund string fragmentation model for hadron production. A model which incorporates interference between identical bosons in the string model is presented. LÄS MER

  5. 4. Medical Laser-Induced Thermotherapy - Models and Applications

    Författare :Christian Sturesson; Lund Kirurgi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; blood perfusion; mathematical modelling; liver tumours; Atomic and molecular physics; benign prostatic hyperplasia; Atom- och molekylärfysik; Fysicumarkivet A:1998:Sturesson; hyperthermia; Coagulation; tissue optical properties;

    Sammanfattning : Heat has long been utilised as a therapeutic tool in medicine. Laser-induced thermotherapy aims at achieving the local destruction of lesions, relying on the conversion of the light absorbed by the tissue into heat. In interstitial laser-induced thermotherapy, light is focused into thin optical fibres, which are placed deep into the tumour mass. LÄS MER

  7. 5. Adsorption of Molecules on Metal Surfaces Studied by High Resolution Core Level Photoemission

    Författare :Andreas Beutler; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Core level photoemission; molecules; adsorption; single crystal surfaces; metals; metal films; vibrations of adsorbed molecules; surface ordering; carbon monoxide; photoelectron spectroscopy; surface diffusion; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:1998:Beutler;

    Sammanfattning : Various aspects of the adsorption of molecules on metal surfaces have been studied making use of different properties of high resolution core level photoemission. A thorough investigation has been performed of the ordering and the site occupancy of CO overlayers on Rh(111). CO has been shown to adsorb in on-top and three-fold-hollow sites. LÄS MER
