  1. 16. Assessment of Myocardial Perfusion with Magnetic Resonance Imaging and an Intravascular Contrast Agent

    Författare :Tomas Bjerner; Christine Lorenz; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Magnetic resonance imaging; Intravascular contrast agents; Myocardial perfusion; Onkologi; Oncology; Onkologi; radiologi; Radiology;

    Sammanfattning : The intravascular contrast agent NC100150 Injection (Clariscan™) was tested for its ability to induce signal intensity changes in myocardium, both in steady state and during first pass, and thereby demarcating non-perfused myocardium from perfused. Steady state: Ex vivo in pigs and when using 4 mg Fe/kg bodyweight (b.w. LÄS MER

  3. 17. Molecular Electronics : A Theoretical Study of Electronic Structure of Bulk and Interfaces

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular electronics; electron transport; disorder; localization; long-range correlation; organometallic magnets; interface dipole; Computational physics; Beräkningsfysik;

    Sammanfattning : This thesis deals with theoretical studies of the electronic structure of molecules used in the context of molecular electronics. Both studies with model Hamiltonians and first principle calculations have been performed. LÄS MER

  4. 18. Materials study of organic electronics

    Författare :Carl Tengstedt; Jérôme Cornil; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The electronic structure of materials for use in organic electronics is studied in this thesis. The first part includes applied research in the form of studies of polymers for use in polymer light emitting devices. LÄS MER

  5. 19. Charge transport modulation in organic electronic diodes

    Författare :Fredrik Lars Emil Jakobsson; Magnus Berggren; Xavier Crispin; Paul W. M. Blom; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic electronics; switch device; memory; photochromic; trapping; resistance switching; Physics; Fysik;

    Sammanfattning : Since the discovery of conducting polymers three decades ago the field of organic electronics has evolved rapidly. Organic light emitting diodes have already reached the consumer market, while organic solar cells and transistors are rapidly maturing. One of the great benefits with this class of materials is that they can be processed from solution. LÄS MER

  7. 20. Interpretation of gamma-ray burst X-ray and optical afterglow emission : From the central engine to the circumburst interaction

    Författare :Liang Li; Felix Ryde; Fawad Hassan; Kim Page; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gamma-ray bursts; central engine; afterglow; teoretisk fysik; Theoretical Physics;

    Sammanfattning : Gamma-ray bursts are the largest electromagnetic explosions known to happen in the Universe and are associated with the collapse of stellar progenitors into blackholes. After an energetic prompt emission phase, lasting typically less than a minute and emitted in the gamma-rays, a long-lived afterglow phase starts. LÄS MER
