  2. 16. Development and Test of an Imaging Instrument for Measurement of Water Droplets in Icing Conditions

    Author : Stefani Alita Leona Rydblom; Benny Thörnberg; Aimé Lay-Ekuakille; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Icing measurements; field study; shadowgraph imaging; edge detection; LWC; MVD.;

    Abstract : Structural icing is a persistent challenge for the production of renewable energy from wind. It is mainly caused by supercooled atmospheric droplets of water, which are very common in cold climates. In the most exposed wind parks in Sweden, more than 10 per cent of annual energy production can be lost. READ MORE

  4. 17. Atmospheric DMS in the High Arctic

    Author : Jenny Lundén; Gunilla Svensson; Caroline Leck; Leonor Tarrason; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DMS; Modelling; Arctic; Meteorology; Meteorologi; meteorologi; Meteorology;

    Abstract : During the Arctic summer when the anthropogenic influence is limited, the natural marine source of sulfur in the form of gas-phase dimethyl sulfide viz. DMS(g), is of great importance for cloud formation. READ MORE

  5. 18. Energy efficiency in the sodium chlorate process: From electrocatalysis to pilot plant investigations

    Author : Kristoffer Hedenstedt; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sodium chlorate; corrosion; mild steel; goethite; lepidocrocite; green rust; hypochlorite reduction; hydrogen evolution; in situ electrochemical Raman spectroscopy;

    Abstract : Sodium chlorate is an important industrial chemical produced through an electrochemical manufacturing process. The global production rate is 3.6 million tons annually and consumes approximately 20 TWh of electrical power. The majority of the produced sodium chlorate is used as raw material to make chlorine dioxide for the bleaching of kraft pulp. READ MORE

  6. 19. Electrochemical reduction of protons and organic molecules in hydrogen technologies : Liquid Organic Hydrogen carrier and Hydrogen Evolution

    Author : Hamid Ghorbani Shiraz; Magnus Berggren; Xavier Crispin; Ola Wendt; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrogen Storage; LOHC; Hydrogen Evolution; Electrocatalyst;

    Abstract : In accordance with preventable actions to mitigate the effect of climate change in the modern societal applications, renewable energy is an unavoidable and decisive factor in the energy industry. The energy sources that offer non-depleted and environment-friendly pathways for the energy sector are in focus. READ MORE

  7. 20. Lifecycle of Black Carbon in the Arctic

    Author : Roxana S. Cremer; Ilona Riipinen; Peter Tunved; Sara Blichner; Hannele Korhonen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Black Carbon; Aerosols; Arctic; lifecyle; absorption; Environmental Sciences; miljövetenskap;

    Abstract : This PhD thesis investigates the atmospheric life cycle of Black Carbon (BC) in the Arctic. The Arctic region has been rapidly changing in the last decades and the role of BC aerosols in this is still uncertain. READ MORE
