  1. 6. Structural Modifications of Lignosulphonates

    Författare :Dimitri Areskogh; Gunnar Henriksson; Arthur J. Ragauskas; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

    Sammanfattning : Lignosulphonates are by‐products from the sulphite pulping process for the manufacture ofspecialty dissolving pulps and paper. During the liberation of the cellulose, the lignin isfractionated and solubilised through covalent addition of sulphonic acid groups at variouspositions in the structure. LÄS MER

  2. 7. Physical properties and processes of secondary organic aerosol and its constituents

    Författare :Kent Salo; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SOA; ageing; VOC; atmosphere; volatility; VTDMA; monoterpenes; ageing;

    Sammanfattning : Atmospheric aerosol particles are involved in several important processes including the formation of clouds and precipitation. A considerable fraction of the ambient aerosol mass consists of organic compounds of both primary and secondary origin. LÄS MER

  3. 8. Modeling of new particle formation and growth in the atmospheric boundary layer

    Författare :Emilie Öström; Centrum för miljö- och klimatvetenskap (CEC); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; New particle formation; Secondary organic aerosols; Process-based modeling; Climate;

    Sammanfattning : Atmospheric aerosols affect climate, but to what degree still remains one of the largest uncertainties in global climate models. To improve the representation of aerosols in future climate models we need a greater understanding of aerosol processes. LÄS MER

  4. 9. Insights into key processes governing atmospheric aerosol loadings and their interactions with clouds

    Författare :Emelie Linnéa Graham; Ilona Riipinen; Claudia Mohr; Paul Zieger; Annica M. L. Ekman; Marianne Glasius; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Aerosol particles are ubiquitous in the atmosphere and an essential part of the atmospheric radiation balance regulating the Earth’s temperature. Aerosol-cloud interaction still remains the largest single uncertainty in future climate projections. In addition, aerosols are also responsible for air pollution, causing severe health effects.
