  1. 6. Biomass Energy Systems and Resources in Tropical Tanzania

    Författare :Lugano Wilson; Weihong Yang; Wlodzimierz Blasiak; Truls Liliedahl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tanzania; Tropical Biomass Energy; High Temperature Gasification HTAG ; Mechanical energy engineering; Mekanisk energiteknik;

    Sammanfattning : Tanzania has a characteristic developing economy, which is dependent on agricultural productivity.  About 90% of the total primary energy consumption of the country is from biomass.  Since the biomass is mostly consumed at the household level in form of wood fuel, it is marginally contributing to the commercial energy supply.

  3. 7. Impact of Radon Ventilation on Indoor Air Quality and Building Energy saving

    Författare :Keramatollah Akbari; Jafar Mahmoudi; Öman Robert; Sylvia Waara; Jan Akander; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical energy engineering; Mekanisk energiteknik; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Industrial living is caused much people do live and work in closed and confined places; offices and residential buildings. This is why in this new world more fresh air which is generally provided by forced ventilation plays a vital role in living of human being. LÄS MER

  4. 8. Correlating Nanostructure and Electronic Properties of Organic Semiconductors by Electron Microscopy

    Författare :Gustav Persson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D; transmission electron microscopy; clustering; molecular dopant; nanostructure; structure-property correlation; visualisation; concentration; organic semiconductor;

    Sammanfattning : Organic semiconductors enable fabrication and efficient processing of electronic devices with light weight, mechanical flexibility and tuneable properties. Despite significant progress in the last decades, efficiencies and long-term stabilities of these systems still need to be improved. LÄS MER

  5. 9. CO2 Separation with Ionic Liquids -Property, Gas solubility and Energy consumption

    Författare :Yujiao Xie; Päivi Elisa Mäki-Arvela; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Ionic liquids (ILs) have shown great potential to be used as liquid absorbents for CO2 capture because of its advantages, such as non-volatility, functionality, high CO2 solubility and lower energy requirements for regeneration. A significant amount of research has been carried out, but most of them are on the synthesis of novel ILs and the measurements of CO2 solubility in ILs. LÄS MER

  7. 10. Process integration in the steel industry : possibilities to analyse energy use and environmental impacts for an integrated steel mill

    Författare :Mikael Larsson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : There is a growing awareness of serious problems associated with the use of energy. These problems include local and global environmental degradation associated with energy use and depletion of resources. LÄS MER
