6. Mineral wool : From landfill to a sustaianble polymer composite
Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : The focus of the project is recycling of the insulation material mineral wool. The aim is to investigate the potential of using post-consumer wool from landfill as fiber reinforcement in a polymer matrix. LÄS MER
7. First principles DFT study of polyethylene insulation containing chemical impurities - implementing counterpoise correction
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Density functional theory (DFT) calculations of polyethylene (PE) HVDC cable insulation have been performed for systems containing four different chemical impurities: acetophenone, cumene, $\alpha$-methyl styrene and $\alpha$-cumyl alcohol. Systems were generated by molecular dynamics (MD) equilibration at four different temperatures relevant for cable insulation applications: 277 K, 293 K, 343 K and 363 K. LÄS MER
8. Technology and market screening for “green” disposable diapers
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : Marknadens påstående om att ”använda så lite plast som möjligt” är vilseledande när 5 av 11 miljövänliga blöjmärken observerades innehålla 80-75% fossil baserad plast. Detta demonstrerar att vilseledande marknadsföring är närvarande på marknaden av miljövänliga engångsblöjor. LÄS MER
9. Conceptual design and construction of a UAV wing structure
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : This report presents the design of the wing structure for a UAV called Skywalker X8. A model of the UAV was given and analyzed to design a wing box structure that is twice the size of the current model, with "greener" technology and lightweight materials. LÄS MER
10. Mapping and investigation of carbon emissions from incineration of plastics : A thesis investigation on common polymers and how they should be managed
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : In November 2016 did the city of Stockholm adapt a strategy on by 2040 only utilizing fossil free fuel in alignment with the national target of reaching net zero carbon emissions by 2045. District heating is a well-established technology in Sweden heating about 50 % of the Swedish households and was in 2015 responsible for 58 % of the total energy demand in buildings and households.
