  3. 17. Release rates and toxicity of metals from anti-fouling paints and the role of chemical speciation

    Författare :Erik Ytreberg; Britta Eklund; Magnus Breitholtz; Christina Rudén; Ingela Dahllöf; Stockholms universitet; []
    Nyckelord :Anti-fouling paints; Toxicity test; Ceramium tenuicorne; Nitocra spinipes; Copper; Zinc; Free Ion Activity Model FIAM ; NATURAL SCIENCES; NATURVETENSKAP; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The aim of this doctoral thesis was to investigate and improve the risk assessment of anti-fouling paints. A new method, the Petri-dish method, was developed to determine release rates of copper and zinc from anti-fouling paints (Paper I). LÄS MER

  4. 18. Fouling of Ultrafiltration Membranes due to Adsorption of a fatty acid

    Författare :Jeanette Lindau; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrafiltration Fouling Adsorption Characterisation ESCA FTIR SEM-EDX Ellipsometry Cleaning Capillary condensation; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : A study of fouling of ultrafiltration membranes due to adsorption of a fatty acid in the membrane matrix has been done. Octanoic acid was used as a model substance. LÄS MER

  5. 19. The Enemy Below - Adhesion and Friction of Ship Hull Fouling

    Författare :Dinis Oliveira; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ship resistance; in-water hull cleaning; roughness; biofouling; hull grooming; frictional resistance; adhesion strength; turbulent boundary layer; hull form factor;

    Sammanfattning : Below the waterline, commercial ships are good targets for marine organisms to attach and proliferate, a problem commonly known as biofouling. A fouled hull means higher hydrodynamic resistance, which can result in significant fuel penalties. LÄS MER

  7. 20. On Alternative Fuels for Internal Combustion Engines : A study of biodiesel, gaseous methane and methanol

    Författare :Ludvig Adlercreutz; Andreas Cronhjort; Ola Stenlåås; Magnus Sjöberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaseous methane combustion; spark ignition; single cylinder research engine; particle number; particle emissions; oil ash content; CO2; Green House Gases; engine testing; engine development; emissions; combustion chamber design; injector fouling; environmental impact; road transportation; Machine Design; Maskinkonstruktion;

    Sammanfattning :  This thesis covers some of the environmental impacts of internalcombustion engines running on alternative fuels. The focus of thestudies conveyed is the reduction of greenhouse gases and particleemissions, as these two factors are of great importance for the pathsthat road transportation is facing. LÄS MER
