  1. 1. Evaluation of different block-copolymer coatings of iron oxide nanoparticles by flash nanoprecipitation

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Felix Bogdan; [2023]
    Nyckelord :Nanopartiklar; organisk katalysator; ROP; block-sampolymerer PL G A; oljesyra IONPs; Nanoparticles; organic catalyst; ROP; block-copolymers PL G A; oleic acid IONPs;

    Sammanfattning : Nanopartiklar (NP) erbjuder unika möjligheter för medicinska tillämpningar, inklusive kontrollerad frisättning av cancerläkemedel, användning som bildkontrast vid avbildningsprocedurer eller hypertermisk behandling av cancerceller. Flash nanoprecipitation (FNP) producerar NPs för att kombinera dessa tillämpningar i en snabb, billig och skalbar beläggningsprocess. LÄS MER

  3. 2. Varnishing of Fiber-based Closures

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Nisha Sunil David; [2023]
    Nyckelord :Varnishing; fiber-based closures; water-based spray coating; packaging; repulpability ; Technology and Engineering;

    Sammanfattning : This research aims to investigate water-based varnishes and technologies to coat fiber-based closures to attain water barrier properties. To ensure recyclability the repulpability of coated and uncoated lids is tested. The research approach is exploratory. LÄS MER

  4. 3. 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. 4. 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. 5. Frosting and Defrosting on Air Source Heat Pump Evaporators

    Master-uppsats, KTH/Energiteknik

    Författare :Camilla Sandström; [2021]
    Nyckelord :;

    Sammanfattning : Air source heat pumps has become increasingly popular for residential households as they are considered an energy efficient alternative on the heating market. The air source heat pumps use the outdoor air as heat source and can operate in cold climates around -15 to -20°C, but as the temperatures drops below 6°C the heat pump experiences problems with frost accumulating on the heat exchanger.
