    Sammanfattning : The CIS solar cell family features both a high stability and world-class performances. They can be deposited on a wide variety of substrates and absorb the entire solar spectrum only using a thickness of a few micrometers. LÄS MER

  3. 2. High resolution microstructural characterization of oxide thin films and interfaces

    Författare :Nikolina Tuzla; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; oxides; Microstructure; TEM; thin films; interfaces; HAADF STEM; YSZ.; SrTiO3; 2DEG; LaAlO3; heterostructures;

    Sammanfattning : Oxide interfaces can introduce properties that are different compared to thecorresponding crystal bulk properties. The properties can be tuned by changing thestructure. It has become clear that these oxide interface systems are potentiallysuitable for future electronic devices with unique and tailored properties. LÄS MER

  5. 4. Particulate airborne impurities : express analysis and health effects

    Författare :Kai Wilkinson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The cumulative effects of air pollutants are of principal concern in research on environmental protection in Sweden. Post-industrial society has imposed many limits on emitted air pollutants, yet the number of reports on the negative effects from them is increasing, largely due to human activity in the form of industrial emissions and increased traffic flows.

  7. 5. Cell wall bulking and distribution of different chemicals in pine, Pinus Sylvestris

    Författare :Lennart Wallström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : The interaction between wood, Pinus sylvestris, (60% RH) and polyethyleneglycol (PEG) of different molecular weights (PEG 200 and PEG 1500), pentaerythritol and glycerol, impregnated into the wood, has been investigated using Scanning Electron Microscopy, EDS-analysis, dynamical mechanical techniques (DMTA), X-ray diffraction (WAXS) and macroscopic dimensional measurement. Reduced dimensional changes after impregnation when exposed to environments with changing moisture content, showed that the stabilization effect of glycerol and PEG 200 impregnation is very good.
