  2. 21. Effects of Energetic Disorder on the Optoelectronic Properties of Organic Solar Cells

    Author : Nikolaos Felekidis; Martijn Kemerink; Olle Inganäs; Carsten Deibel; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Organic photovoltaics (OPVs) is a promising low-cost and environmental-friendly technology currently achieving 12-14% power conversion efficiency. Despite the extensive focus of the research community over the last years, critical mechanisms defining the performance of OPVs are still topics of debate. READ MORE

  4. 22. Estimating the Air-Water Gas Transfer Velocity during Low Wind Conditions

    Author : Sam Fredriksson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Air.sea gas exchange; Turbulence; Heat flux; Natural convection; Shear; Direct numerical simulations; Gas transfer velocity; IR; Flux-chambers;

    Abstract : The abundances of atmospheric carbon dioxide, CO2, and methane, CH4, are increasing. These increases affect e.g., the global carbon cycle and the climate both regionally and globally. READ MORE

  5. 23. Substrate water binding to the oxygen-evolving complex in photosystem II

    Author : Håkan Nilsson; Johannes Messinger; Wolfgang Schröder; Robert L. Burnap; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photosynthesis; Photosystem II; water oxidation; oxygen evolution; substrate water exchange; membrane-inlet mass spectrometry;

    Abstract : Oxygenic photosynthesis in plants, algae and cyanobacteria converts sunlight into chemical energy. In this process electrons are transferred from water molecules to CO2 leading to the assembly of carbohydrates, the building blocks of life. READ MORE

  6. 24. Advanced measurement and modelling methods for noise source analysis

    Author : Matti Rantatalo; Mats Åbom; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Abstract : In daily life sound is a vital dimension for the perception of the world around us but can in some cases be considered as annoying, irritating, or even harmful. In these cases the sound is labelled as noise and can be addressed in two ways, either by insulating the noise problem from the receiver (person) or by altering the source. READ MORE

  7. 25. Physical and Chemical Aspects of Radiation Induced Oxidative Dissolution of UO2

    Author : Olivia Roth; Mats Jonsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; UO2; spent nuclear fuel; dissolution; oxidation; radiolysis; irradiation; particle size; modeling; Chemistry; Kemi;

    Abstract : Denna licensiatavhandling behandlar oxidativ upplösning av UO2. Upplösning av UO2 studeras huvudsakligen då UO2-matrisen hos använt kärnbränsle förväntas fungera som en barriär mot frigörande av radionuklider i ett framtida djupförvar. READ MORE
