    Sammanfattning : Environmental and health aspects of road materials have been discussed for a long time, mostly regarding bitumen and bitumen fumes. However, just a few studies on other types of road materials have been reported. LÄS MER

  4. 3. Enhancement of the Tribological Properties of Plasma Sprayed Alumina

    Författare :Richard Westergård; Richard Warren; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Thermal spraying is the name of a large group of coating deposition techniques used to deposit thick layers for a variety of applications. The principle is to melt the material, and rapidly propel the droplets towards a substrate where they flatten and solidify. When properly used, the substrate is not significantly heated. LÄS MER

  5. 4. Sources, emissions, and occurrence of chlorinated paraffins in Stockholm, Sweden

  7. 5. Long-term performance of polymeric materials in nuclear power plants

    Författare :Payam Pourmand; Ulf W. Gedde; Sue Burnay; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; EPDM; thermal ageing; radiation ageing; portable NMR spectroscopy; modulus profiling; condition monitoring; plasticizer migration; Kemi; Chemistry;

    Sammanfattning : Access to energy is crucial for modern societies to function sustainably. In addition, nuclear power has for a long time been considered a reliable source of energy. However, the majority of nuclear power plants are reaching the end of their service lifetimes, and it is crucial to verify that every component can withstand the added service time. LÄS MER
