  1. 11. Numerisk modellering av deformationer i ett modellförsök på torv

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Denise Marchesoni; Pehr Nortén; [2023]
    Nyckelord :;

    Sammanfattning : There are limitations in the knowledge of ​​peat in terms of the material's properties and how peat deforms and therefore research in the area is necessary. Peat is common over large parts of Sweden. LÄS MER

  3. 12. Quality Assurance of Recycled HDPE in the Plastic Packaging Industry

    Master-uppsats, Lunds universitet/Innovation

    Författare :Tora Abrahamsson; Juliana Kalling; [2023]
    Nyckelord :Thermoforming; Plastics; Recycling; Packaging Industry; HDPE; Technology and Engineering;

    Sammanfattning : The recycling of plastic has the potential to support circular material use, thus decreasing the need for virgin plastics. However, there is an existing issue with assuring quality of recycled plastic materials, causing finished products to perform with poorer properties and unexpected deviations. LÄS MER

  4. 13. Micromechanical Characterization of Thin Paper Materials

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola

    Författare :Linus Bengtsson; [2023]
    Nyckelord :Micromechanical characterization; SEM; In situ tensile testing; Paper deformation; Fiber orientation; Paper mechanics; Technology and Engineering;

    Sammanfattning : Hur ser framtidens hållbara förpackning ut och vad är den tillverkad av? För att besvara denna fråga blir mikromekanisk karakterisering av material en viktig parameter att utforska och förstå. I synnerhet är mikromekaniken hos tunna pappersmaterial intressant då materialet har användningspotential i flera förpackningsapplikationer. LÄS MER

  5. 14. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Douglas Björkengren; [2023]
    Nyckelord :polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

    Sammanfattning : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.

  7. 15. Synthesis and characterization of lactic acid-based elastomers

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Afsaneh Makhdoumi; [2023]
    Nyckelord :Lactic acid; Elastomer; Bio-based elastomer; Renewable resource;

    Sammanfattning : Synthesized polymer from bio-based and renewable resources reported as an attractive substitution for fossil-fuel based polymers. Therefore, this work has focused on using sustainable material for production of elastomers to reduce the environmental impact of fossil-based elastomers and overcome the shortage of non-renewable fuels.
