  1. 1. Water Condensation and Freezing in the Atmosphere: Exploring Deliquescence and Ice Nucleation

    Författare :Dimitri Castarède; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hygroscopicity; Deliquescence; Atmosphere; Particles; Ice Nucleation; Ice Nucleation Chamber;

    Sammanfattning : Atmospheric aerosols play key roles in numerous atmospheric processes. They affect human health, are substrates and components for atmospheric chemistry, and via their contribution to clouds affect the water cycle and the energy balance of the planet. LÄS MER

  2. 2. Experimental Studies on Ambient Aerosol Hygroscopicity

    Författare :Erik Fors; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysicumarkivet A:2011:Fors;

    Sammanfattning : The air around us is full of aerosol particles which originate from a myriad of sources and which have vastly different chemical and physical properties. These particles span size ranges from 1 nm to 100 μm, equivalent to a factor 100 000 in diameter difference and a factor 10^15 in volume difference. LÄS MER

  3. 3. Cloud Droplet Forming Potential of Ageing Soot and Surfactant Particles : Laboratory research and Köhler modelling

    Författare :Cerina Wittbom; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :Hygroscopicity; CCN; BC;

    Sammanfattning : Aerosol particles affect Earth’s climate system by scattering and absorbing light. The perturbation of the climate system caused by a change in aerosol configuration due to anthropogenic emissions has recently improved. LÄS MER

  4. 4. Black Death - Blue Skies - White Clouds : Water Vapour Uptake of Particles Produced from Traffic Exhaust and their Effect on Climate

    Författare :Cerina Wittbom; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCN ACTIVATION; Soot; water vapour; climate; SOA; Traffic emission; Fysicumarkivet A:2017:Wittbom;

    Sammanfattning : Aerosol particles are everywhere in the air around us, regardless of whether you are in a busy city or in the serene Arctic. Airborne particles can be produced naturally or anthropogenically, and their properties changes during the time they spend in the atmosphere. LÄS MER

  5. 5. Characterisation of thermally modified wood for use as component in biobased building materials

    Författare :Susanna Källbom; Magnus Wålinder; Dennis Jones; Kristiina Lillqvist; Kristoffer Segerholm; Marko Petrič; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thermally modified wood TMW components; surface properties; inverse gas chromatography IGC ; water sorption; dynamic vapour sorption DVS ; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : The building sector shows growing interest in biobased building materials. Wood components, here defined as ground or milled wood, i.e. by-products (residuals/residues) from wood processing, such as sawdust or shavings, are valuable raw materials for new types of durable biocomposites suitable for outdoor building applications.
