  1. 1. 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

  3. 2. GRAPHENE MODIFIED E-TEXTILE : AN INDUSTRY RELEVANT APPROACH OF DOPING AND VISUALISING A FULLY TEXTILE P-N JUNCTION DIODES

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

    Författare :Bilel Meskini; [2023]
    Nyckelord :E-textile; viscose; polyester; graphene; graphene oxide GO; reduced graphene oxide rGO; tannic acid; plasma treatment; electrochemical deposition; doping; semiconductor;

    Sammanfattning : As a wonder material, graphene has been studied in various applications due to its exceptional properties. Recently it has been used in textile to obtain functionalised garments as E-textile. From an industry-relevant perspective, it is essential to introduce a process that could be scaled-up. LÄS MER

  4. 3. Multifunctional ice and snow repellent coatings for photovoltaic modules

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik

    Författare :Gunnar Sandkvist; [2023]
    Nyckelord :sol-gel; superhydrophobic; dip-coating; anti-reflective; silica;

    Sammanfattning : Implementation of solar power by photovoltaic modules in cold climates, such as northern Sweden, implies several challenges. Ice and snow coverage not only leads to reduction in energy production due to shading, but it also puts equipment at risk from additional weight. LÄS MER

  5. 4. 3D Coating of Interface Materials for High-Performance RF Passive Devices

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

    Författare :Xiner Shen; [2023]
    Nyckelord :Ceramic coating; Dip coating; Radio frequency; Passive RF devices; Quality factor; Keramisk beläggning; Dip-beläggning; Radiofrekvens; Passiva RF-enheter; Kvalitetsfaktor;

    Sammanfattning : The demand for high-performance Radio Frequency (RF) passive devices has been steadily increasing due to the growing complexity and sophistication of wireless communication systems. The Quality factor (Q-factor) is a key parameter for describing the signal losses and the energy efficiency of resonators. LÄS MER

  7. 5. Effect of ash on catalytic activity for passive regeneration of catalytic diesel particulate filter : Evaluation of ash deposition by laboratory ageing

    Master-uppsats, KTH/Kemiteknik

    Författare :Gisela Engström; [2022]
    Nyckelord :Diesel Particulate Filter; Ash deposition; Laboratory Ageing; Catalytic Activity; Passive regeneration;

    Sammanfattning : Askackumulering i dieselpartikelfilter är ett välkänt problem som resulterar i ett förhöjt mottryck och påverkad prestanda hos fordonet. Däremot ges sällan uppmärksamhet åt filtrets katalytiska aktivitet och hur det påverkas vid förekomst av avgasföroreningar. LÄS MER
