  2. 16. Molecular mechanisms of nitrogen dioxide induced lung damage

    Author : Ba Tu; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Nitrogen dioxide (NO2) is an oxidant gas which contaminates ambient air in many urban and industrial locations, and indoor air in homes with combustion appliances. The Environmental Protection Agency (USA) regulates N02 in ambient air as a "criteria" pollutant. READ MORE

  4. 17. Validation of diffusive samplers for nitrogen oxides and applications in various environments

    Author : Annika Hagenbjörk-Gustafsson; Kåre Eriksson; Greta Smedje; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nitrogen dioxide; NOx; diffusive sampling; validation; vehicle exhaust; exposure measurement;

    Abstract : The overall aim of this thesis was to validate diffusive samplers for measurements of nitrogen dioxide (NO2) and nitrogen oxides (NOx). The Willems badge was validated for NO2 measurements both in laboratory tests and in field tests (Paper I-II). The sampling rate was 40.0 mL/min for ambient air concentrations and 46. READ MORE

  5. 18. Influence of the Gas Phase on Pretreatment of Kraft Pulp with Nitrogen Oxides

    Author : Dennis Rasmusson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nitric oxide; oxygen; acid hydrolysis;

    Abstract : While nitric oxide (NO) is virtually inert against water-impregnated kraft pulp it participates in important reactions when reactive nitrogen compounds, e.g. NO2 and HNO2, have initiated lignin reactions. Experiments with kraft lignin (Indulin AT) showed that nitric oxide was both produced and consumed during treatment with NO2. READ MORE

  6. 19. Bonding and Diffusion of Molecules in Zeolites by ESR and ENDOR

    Author : Haitao Li; Eli Olaug Hole; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis studies bonding and diffusion of molecules in zeolites by Electron Spin Resonance (ESR) and Electron Nuclear Double Resonance (ENDOR). In the first part an introduction is given. In the second part (chapter 2) the detailed structure of a Cu2+ complex with water molecules in Cu-ZSM-5 zeolite was characterized with ENDOR at 4 K.

  7. 20. Absorption Based Systems for Co-removal of Nitrogen Oxides and Sulfur Oxides from Flue Gases

    Author : Jakob Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SOx; absorption; ClO2; sulfite oxidation; gas-phase oxidation; NOx; Emissions control; scale-up;

    Abstract : Enhanced control of nitrogen and sulfur emissions, found in many of industrial processes, is anticipated for decades to come. Stricter emission regulations require new technologies adapted to the new conditions at reasonable cost. READ MORE
