  1. 31. High-Temperature Cooling Systems for Sustainable Buildings Using Geothermal Energy : Holistic Assessment in the Mediterranean Climate

    Författare :Henrikki Pieskä; Johan Silfwerbrand; Adnan Ploskic; Qian Wang; Sture Holmberg; Sasan Sadrizadeh; Ambrose Dodoo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radiant cooling; Geothermal cooling; Energy efficiency; Thermal comfort; Sustainable development; Strålningskylsystem; Geotermisk kyla; Energieffektivitet; Termisk komfort; Hållbar utväckling; Strömnings- och klimatteori; Fluid and Climate Theory;

    Sammanfattning : Sustainable development is increasing its significance in both the scientific and political agenda. In light of this development, the United Nations have published 17 Sustainable development goals (SDGs). LÄS MER

  2. 32. Surface Reactions During Atomization, Handling and Consolidation of Al-powders

    Författare :Anders Nylund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Surface reactions during atomization and consolidation of pure Al and the alloys Al2Mg, Al5Mn2.5Cr, Al5Mn6Cr and Al8Fe2Mo were studied by using ESCA, SAM and SEM. The powders were analysed in the as-atomized condition and after exposure to humid atmosphere. The powders were atomized by using the USGA (Ultra Sonic Gas Atomization)-technique. LÄS MER

  3. 33. Nanotemplated High-Temperature Materials for Catalytic Combustion

    Författare :Erik Elm Svensson; Sven Järås; Magali Boutonnet; James J. Spivey; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon templating; Catalytic combustion; Ceria; Gas turbine; Hexaaluminate; Magnesia; Methane; Microemulsion; Perovskite; Chemical engineering; Kemiteknik;

    Sammanfattning : Catalytic combustion is a promising technology for heat and power applications, especially gas turbines. By using catalytic combustion ultra low emissions of nitrogen oxides (NOX), carbon monoxide (CO) and unburned hydrocarbons (UHC) can be reached simultaneously, which is very difficult with conventional combustion technologies.

  4. 34. Radiation induced corrosion of copper

    Författare :Åsa Björkbacka; Mats Jonsson; Christofer Leygraf; Mehran Mostafavi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Corrosion; oxidation; copper; copper oxide; gamma radiation; radiolysis; hydrogen peroxide; hydroxyl radical; Kemi; Chemistry;

    Sammanfattning : The process of radiation induced corrosion of copper is not well understood. The most obvious situation where the knowledge of this process is crucial is in a deep repository for high level spent nuclear fuel where the fuel will be sealed inside copper canisters. LÄS MER

  5. 35. Iodine-Metal Surface Interactions under Severe Accident Conditions in a Nuclear Power Plant

    Författare :Henrik Glänneskog; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; containment; reactive metals; BWR; adsorption; iodine; radiolysis;

    Sammanfattning : In the event of a severe nuclear reactor accident, iodine will be released from the fuel and eventually enter the containment. Radioactive iodine isotopes constitute both an acute and a long-term threat to humans, owing to its half-life and its accumulation in the thyroid gland. LÄS MER
