  2. 21. Physical Characterization of Actinide Particles - A Study on Novel Techniques for Radiological and Nuclear Safeguard Investigations

    Author : Ylva Ranebo; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; plutonium oxide particles; secondary ion mass spectrometry; uranium oxide particles; hot particles; vibrating orifice aerosol generator; scanning electron microscopy; nuclear safeguards;

    Abstract : This thesis presents a study of advanced analytical techniques, for the characterization of actinide particles originating from the non-peaceful use of nuclear technology and from international inspections of the nuclear fuel cycle associated with non-proliferation agreements. The thesis is based on five papers, which will be referred to by Paper I-V in the text. READ MORE

  4. 22. Cloud Studies with the Droplet Aerosol Analyzer

    Author : Maria Berghof; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cloud; Aerosol; DAA;

    Abstract : Climate change and atmospheric aerosols are a threat for human health and life. Reducing aerosol emissions would save human lives close to the aerosol source, but could lead to more death due to the implications of a warmer climate. READ MORE

  5. 23. On the lifecycle of aerosol particles : Sources and dispersion over Scandinavia

    Author : Peter Tunved; Hans-Christen Hansson; Johan Ström; Douglas Nilsson; Urs Baltensperger; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aerosols; Meteorology; Meteorologi;

    Abstract : Aerosol particles are likely important contributors to our future climate. Further, during recent years, effects on human health arising from emissions of particulate material have gained increasing attention. READ MORE

  6. 24. Chemical and Morphological Characterisation of Aerosol Particles in the Tropopause Region

    Author : Hung Nguyen Ngoc; Kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CARIBIC; Physics; Singel particle analysis TEM and EFTEM; Carbon and Sulphur; Light element analysis; Aerosol sampler; Chemical Characterisation; Aerosol in the Tropopause Region; Nuclear physics; Technological sciences; Fysik; Teknik; Kärnfysik; Fysicumarkivet A:000;

    Abstract : The aim of this work was to study atmospheric aerosols, focusing on the chemical composition, the morphology and the origin of the aerosol in the upper troposphere and lowermost stratosphere. An aerosol sampler was developed for this purpose. A new method for quantitative analysis of the major components of the aerosol, i.e. READ MORE

  7. 25. Char conversion kinetics and aerosol characterization in biomass gasification

    Author : Leteng Lin; Michael Strand; Alberto Gómez-Barea; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass gasification; fluidized bed; char; kinetics; aerosol; APS; TEOM; Bioenergiteknik Energi- och Miljöteknik; Bioenergy Technology;

    Abstract : Biomass gasification is a thermochemical conversion by partial oxidation at elevated temperature of solid biomass into a gaseous energy carrier. The product gas contains the major components CO, H2, CO2, CH4, as well as some tar and inorganic impurities and solid particles such as ash, bed material, soot and char. READ MORE
