  2. 16. Poly(Alkylthiophene) Blends Processing, Morphology and Conductivity

    Author : Nils Ljungqvist; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Intrinsically conducting polymers may be an attractive alternative instead to polymers with conducting fillers. The aim of the present work was to study the potential of the processable conducting polymer poly(3-alkylthiophene) as well as possible problems related to its processing. READ MORE

  4. 17. Magnetotransport and Persistent Currents in Ballistic Microstructures

    Author : Thomas Swahn; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this Thesis we discuss properties of different ballistic microstructures in the presence of a magnetic field. Three topics have been studied: (i) the magnetoconductance of a three-dimensional (3D) microwire, (ii) magnetotransport and persistent currents in a two-dimensional so called "quantum dot" in a gated AlGaAs heterostructure, and (iii) some magnetotransport properties of a quasi one-dimensional conducting channel in the same kind of material.

  5. 18. Studies on host-related pathogenesis of herpes simplex type-1 encephalitis in rat

    Author : Biborka Bereczky-Veress; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : In order to explore the molecular mechanisms of Herpes simplex encephalitis (HSE), a severe infection of the central nervous system (CNS) caused by Herpes simplex type 1 virus (HSV-1); a rat model resembling the human condition was characterized in the DA (Dark Agouti) strain. After injection into the whiskers’ area HSV-1 entered the CNS at the level of the brain stem via the trigeminal ganglion, subsequently spreading to the thalamus, cortex and olfactory bulb, leading to death at five days post infection (dpi).

  6. 19. Mixed metal oxide - noble metal catalysts for total oxidation of volatile organic compounds and carbon monoxide

    Author : Magali Ferrandon; KTH; []
    Keywords : wood combustion; catalysts; total oxidation; manganese; copper; platinum; palladium; lanthanum; cerium; CO; VOC; methane; deactivation; thermal stability; sulphur dioxide;

    Abstract : CO, volatile organic compounds, and polyaromatics areubiquitous air pollutants that give rise to deleterious healthand environmental effects. Such compounds are emitted, forinstance, by the combustion of wood, particularly fromsmall-scale heating appliances. READ MORE

  7. 20. Engineering Ceramics for Tribological Systems. Manufacture, Properties and Testing

    Author : Lars Kahlman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal wear; ceramic composite; face seal; engineering ceramic; erosion; hybrid bearing; thermal spalling; lubrication; tribology; abrasive waterjet; abrasive wear;

    Abstract : A broad range of commercial and experimental grades of ceramics and ceramic composites was tested in various model tests and simplified component tests. The tests were done to establish important microstructural features, friction and wear mechanisms. READ MORE
