  1. 16. Zinc Oxide Bulk and Nanorods

    Författare :Peter Klason; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; zinc oxide; Schottky contact; buckling; annealing; semiconductor growth; ion implantation; photoluminescence; nanorods;

    Sammanfattning : Zinc Oxide (ZnO) has many promising properties for optoelectronics, sensor applications, transparent electronics etc. To mention a few, ZnO has a large exciton binding energy (60 meV at room temperature) and a direct wide bandgap energy of 3.37 eV. In addition, ZnO is piezoelectric and shows more resistance to radiation damage than Si and GaN. LÄS MER

  4. 19. Endogenous Nitric Oxide Production and Pulmonary Blood Flow : during different experimental lung conditions

    Författare :Manja Nilsson; Filip Fredén; Kristina Hambraeus-Jonzon; Göran Hedenstierna; Eddie Weitzberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nitric oxide; pulmonary blood flow; endotoxin; nitric oxide inhalation; endothelin; hypercapnia; acidosis; lavage-induced lung injury; Anaesthetics and intensive care; Anestesiologi och intensivvård; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : Nitric oxide (NO) is an important regulator of pulmonary blood flow and attenuates hypoxic pulmonary vasoconstriction (HPV). Nitric oxide is synthesized enzymatically in a number of tissues, including the lungs, and can also be generated from reduction of nitrite during hypoxia and acidosis. LÄS MER

  5. 20. Exhaled Nitric Oxide in epidemiological and experimental studies

    Författare :Anna-Carin Olin; Göteborgs universitet; []
    Nyckelord :Nitric oxide; exhaled air; nasal nitric oxide; ozone; pulp-mill; gassings; nitrate; ; atopy; sensitization; asthma; rhinitis; bronchiolitis;

    Sammanfattning : The overall purpose with this thesis has been to contribute to the assessment of theutility of exhaled nitric oxide (eNO) in epidemiological studies. The specific aims have been toinvestigate whether eNO increases after occupational exposure to high peaks of ozone, or afterexperimental exposure to ozone in ambient concentrations. LÄS MER
