  1. 1. Varnishing of Fiber-based Closures

    University essay from Lunds universitet/Förpackningslogistik

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

    Abstract : 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. READ MORE

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

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

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

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Solcellsteknik

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

    Abstract : 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. READ MORE

The doubly fed induction generator (DFIG) isthe mainstream choice for wind turbine generator (WTG) in current market andthe object of this thesis. READ MORE

  6. 5. Evaluation of influence from matedness on the peak shear strength of natural rock joints

    University essay from KTH/Byggvetenskap

    Author : Emil Andersson; [2019]
    Keywords : Rock joints; Peak shear strength; Matedness; Casagrande et al. criterion; Peak friction angle; Shear strength; Bergssprickor; Maximal skjuvhållfasthet; Passning; Casagrande et al. kriterium; Friktionsvinkel; Skjuvhållfasthet;

    Abstract : In Sweden, the rock mass is commonly used for construction of tunnels and caverns. The rockmass is also used as a foundation for large structures such as bridge abutments and dams. Forthese structures, the understanding of the rock mechanical properties play a key role for reachingan acceptable safety level and minimizing cost. READ MORE
