  1. 21. Development and Optimization of Near-infrared spectroscopy

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Amanda Hahlin; [2023]
    Nyckelord :Near-infrared spectroscopy; NIRS; Textile sorting; Principal component analysis; PCA; Post-consumer end-of-life textiles;

    Sammanfattning : With the growing demand for sustainable options, the existing sorting capacities are limiting the potential for fiber-to-fiber recycling. With the help of near-infrared spectroscopy (NIRS), automated sorting of textiles with high accuracy is possible due to the easy access for polymer identification. LÄS MER

  3. 22. Improvement and verification of a pin-on-disc tribometer with variable speed and load

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Valentine Lin; [2023]
    Nyckelord :tribometer; friction; tribometer; friktion;

    Sammanfattning : The use of threaded fasteners can be found throughout the manufacturing industry due to their simplicity. When tightening a threaded fastener, the goal is to reach a desired clamping force. However, the clamping force is not directly measurable in production environments and the tightening torque is instead used to estimate the clamping force. LÄS MER

  4. 23. Development of chitosan nanocomposite coatings for visible-light photocatalytic antiviral applications

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Michael Neuman; [2023]
    Nyckelord :Biopolymer; Chitosan; Coating; Nanocomposite; Photocatalytic; Zinc oxide; Antimicrobial; Antiviral; Coronavirus COVID-19 ; Biopolymer; Kitosan; Beläggning; Nanokomposit; Fotokatalytisk; Zinkoxid; Antimikrobiell; Antiviral; Coronavirus COVID-19 ;

    Sammanfattning : During the global pandemic of coronavirus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak, the world was desperately searching for simpler yet more effective solutions to stop the spread of coronavirus (COVID-19). Since no one was prepared for the fast spread of such a contagious virus, there was a shortage of proper protective solutions to stop the spread. LÄS MER

  5. 24. A Study on Lignin or Zein Based Hydrophobic Coatings

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Filippa Wentz; Sandra Olofsson; [2023]
    Nyckelord :Lignin; Zein; Hydrophobic Coating; Dispersion; Chemical engineering; Technology and Engineering;

    Sammanfattning : The two by-products lignin, from the paper industry, and zein, from starch production, have shown potential as hydrophobic barriers. Therefore, this study has aimed to produce and in-vestigate the hydrophobicity of lignin or zein dispersions coated on paper. LÄS MER

  7. 25. Projection Nut Welding to High- and Ultra-high Strength Steels

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Love Englund; [2023]
    Nyckelord :mechanics; solid mechanics; material mechanics; welding; resistance welding; projection welding; nut welding; high strength steel; ultra high strength steel; uhss; coated boron steel; mekanik; hållfasthetslära; materialvetenskap; svetsning; motståndssvetsning; projektionssvetsning; muttersvetsning; belagt borstål;

    Sammanfattning : In an effort to increase the fuel efficiency of cars more widespread use of higher strength steels is seen for their high strength-to-weight ratio. Thesesteels are more limited in their formability and tendency to harden than conventional steels, complicating manufacturing. LÄS MER
