  1. 1. Formulation and characterisation of novel edible-packaging for fruits and vegetables

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Lola Sutton; Katerina Papa; [2023]
    Nyckelord :algae; edible packaging; carrageenan; cucumber; REL; oxidative stress; antioxidants; food engineering; Technology and Engineering;

    Sammanfattning : This master's thesis investigated the potential of algae raw materials, specifically k-carrageenan and to a lesser extent alginate, as film-forming ingredients for the development of a novel edible packaging solutions. The project involved the testing and characterisation of several active ingredients of algal and plant origins both as extracts and as ingredients in films. LÄS MER

  3. 2. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Muhammad Umar Farooq; [2023]
    Nyckelord :Ball bearing; electric drivetrain; tribology; electric field; characterization; bearing currents; discharge;

    Sammanfattning : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces. LÄS MER

  4. 3. Optical properties in chalcogenide glasses and their temperaturedependence. : Literary survey and experiments.

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Matilda Karlsson; Saifallah Khaled Ali; Erik Lundqvist; Ask Löthman Ybo; Kalle Sigås; Oscar Törnquist; [2023]
    Nyckelord :Chalcogenide materials; Chalcogenide glass; Optical properties; Temperature dependence;

    Sammanfattning : This study aimed to investigate methods for determining the temperature dependence of the refractive index and absorption of IR-transparent materials through literary studies and experimental tests. Results from the experimental trials were hard to obtain due to the inherent difficulty of measuring optical properties and yielded only temperature trends of transmittance and reflectance. LÄS MER

  5. 4. Review of pH recommendations for soilless cultivation systems

    Kandidat-uppsats, SLU/Dept. of Crop Production Ecology

    Författare :Elric Fabricius; [2023]
    Nyckelord :soilless cultivation; hydroponics; aeroponics; NFT; nutrient film technique; DWC; deep water culture; pH; nutrient solution; speciation; availability; biomass production;

    Sammanfattning : Our human population is growing, and with that, so is our demand for food, food that today still is not a guarantee for all of us. To help increase global food security, the diversification of our food production through the implementation of soilless, hydroponic cultivation systems has been suggested. LÄS MER

  7. 5. Impact of nanoparticle plasmons on photoluminescense and upconversion processes in ZnO

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik; Uppsala universitet/Fysikalisk kemi

    Författare :Axel Gudmundsson; [2023]
    Nyckelord :Photoluminescence; Upconversion; Plasmons; ZnO;

    Sammanfattning : The increasing prevalence of glass windows in modern buildings has raised the demand for solar control windows that possess climate-appropriate properties. Glass windows made of abundant and low-cost materials which can both decrease the heating energy consumption as well as enhance the light climate indoors would sufficiently meet the goals of economical yet uplifting buildings.
