  1. 1. Thermal degradation of PFAS in solid matter

    Master-uppsats, KTH/Kemi

    Författare :Tuqa Al-Badri; [2024]
    Nyckelord :PFAS; PFOS; PFOA; thermal degradation; sewage sludge; PFAS; PFOS; PFOA; termisk nedbrytning; avloppsslam;

    Sammanfattning : Per- och Polyfluorerade alkylsubstanser (PFAS) är syntetiskt framställda organiska föreningar som har använts i stor utsträckning i konsument- och industriprodukter. PFAS-substanser besitter attraktiva egenskaper såsom resistans mot väta, fett, fläckar och är dessutom värmetåliga. LÄS MER

  3. 2. FRÅN VITT TILL GRÖNT, RÖTT ELLER BRUNT: Kan blindering åtgärdas med kunskap vi redan har?

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Annica Drotz; [2023-11-07]
    Nyckelord :blanching; oil paint; bloom; paint layer; accelerated aging; consolidation;

    Sammanfattning : Blanching is a common phenomenon affecting the binding medium within the paint, resulting in an abnormality of the paints light scattering. Multiple studies have confirmed that the change is the result of pore formation within the binding medium caused by humidity or water damage. LÄS MER

  4. 3. Relationship between Fatigue Properties and Surface Treatment of Aluminum Alloy

    H-uppsats,

    Författare :Umair Ali Khan; Soroosh Zahedi; [2023-09-14]
    Nyckelord :Corrosion resistance; Fatigue; Aluminium alloys; HPDC; PMC; Sheet Metal; Anodization Molding; Casting;

    Sammanfattning : Corrosion has posed a significant challenge within the maritime sector for numerousyears. In the 21st century, bolstering the corrosion resistance of alloys, particularlyaluminum alloys, has become paramount. Aluminum alloys find widespread use inpropulsion systems, boat hulls, and cargo vessels. LÄS MER

  5. 4. The atmospheric effects of Southern Ocean open-ocean polynyas onto the coastal polynyas from EC-Earth3

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Jakob Gunnarsson; [2023-05-10]
    Nyckelord :;

    Sammanfattning : Polynyas are recurring areas of open water or thin ice within the sea ice pack, which alter the local oceanatmosphere heat and moisture exchange. They are differentiated as coastal (latent heat) or open-ocean (sensible heat) polynya according to their formation process. LÄS MER

  7. 5. CFD-modeling of labyrinth weir flood discharge with ice cover

    Master-uppsats, KTH/Betongbyggnad

    Författare :Erik Isberg; [2023]
    Nyckelord :;

    Sammanfattning : A labyrinth weir is a hydraulic structure built with a purpose to increase the discharge capacity compared to linear weirs, while maintaining the same water level upstream. Construction of labyrinth weirs is vital in a future with more unpredictable flows. LÄS MER
