  2. 16. Halogenated organic matter in precipitation

    Author : Krzysztof Laniewski; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Deposition in rain and snow plays a crucial role in the regional and global redistribution of a great variety of substances. This thesis is devoted to chemical characterisation and identification of the halogenated organic compounds that are most widespread in rain and snow. READ MORE

  4. 17. On the Chemical Romance Between Gas and Surface, and how to Illuminate it

    Author : Sebastian Pfaff; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; planar laser-induced fluorescence; surface optical reflectance; model catalysis; palladium; polycrystal; CO oxidation; heterogeneous catalysis; Fysicumarkivet A:2022:Pfaff;

    Abstract : An increasing number of catalysis experiments are conducted at higher pressures to bridge the pressure gap. This means that we need to measure not only the sample surface but also the gas phase around the sample with spatial resolution. READ MORE

  5. 18. Primordial radionuclides in pit lakes in Sweden

    Author : Rimon Thomas; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; non-uranium mines; water; sediment; radiochemistry; principle component analysis;

    Abstract : In Sweden, there are many pit lakes, originating from limestone quarries and metal mines, with unknown status in regard to the activity concentration of radionuclides. Such knowledge is generally available only for pit lakes from uranium mining activi-ties. READ MORE

  6. 19. Novel detection schemes and high resolution separations in microcolumn liquid separations

    Author : James N. Alexander; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Chemistry; Kemi; Analytical Chemistry; analytisk kemi;

    Abstract : Three micro detectors were developed and studied using micro-liquidchromatography (micro-LC). An evaporative light scattering detector (ELSD) nebulizer was developed for use with flow rates ranging from 0.5 to 10 µL/min. READ MORE

  7. 20. Marine biogenic polysaccharides as a potential source of aerosol in the high Arctic : Towards a link between marine biology and cloud formation

    Author : Qiuju Gao; Caroline Leck; Ulrika Nilsson; Eric Saltzman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polysaccharides; Biogenic polymer microgels; Arctic Ocean; LC MS MS; Surface microlayer; Marine aerosol particles; Remote marine cloud condensation nuclei; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Primary marine aerosol particles containing biogenic polymer microgels play a potential role for cloud formation in the pristine high Arctic summer. One of the major sources of the polymer gels in Arctic aerosol was suggested to be the surface water and more specifically, the surface microlayer (SML) of the open leads within the perennial sea ice as a result of bubble bursting at the air-sea interface.
