  1. 1. A PILOT STUDY ON STAIN REDUCTION Effects of Stains, Cleaning Agents, and Cleaning Methods on Polyester Textiles

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Karin Hindborg; [2023-08-28]
    Keywords : colour measurements; spot cleaning; suction table; tensile testing; textile con-servation;

    Abstract : The thesis was an experimental pilot study that investigated efficiency and effects of stains and cleaning agents on polyester textiles. A literature review and interviews with textile conservators were used to understand the degradation of polyester fibres and to find suit-able staining and cleaning agents to use in the experiments of the study.

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

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

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

    Abstract : 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. READ MORE

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Author : Rebecka Ståhl; Parvathy Biju; [2023]
    Keywords : Alertness; Circadian Entrainment; Clear Sky; Correlated Colour Temperature; Daylighting; Direct Electric Lighting; Direct-Indirect Electric Lighting; Energy-Efficiency; Grasshopper; Integrative Lighting; LARK 2.0; Melanopic Equivalent Daylight Illuminance; Overcast Sky; Photopic Illuminance; Spectral Power Distribution.; Technology and Engineering;

    Abstract : Human beings in modern society spend more than 90% of their time indoors to live, work, and socialize. To improve health, quality of life and task performance, integrative lighting is designed to give the right light at the right time at the eye to stimulate circadian entrainment. READ MORE

  5. 4. Investigation of the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Gila van den Eijnde; [2023]
    Keywords : Hard candy; Sugar composition; Hygroscopicity; Moisture absorption; Shelf life; Product stability; Food technology; Technology and Engineering;

    Abstract : Hard candy is hygroscopic, implying that hard candy readily absorbs moisture from the environment, resulting in adverse changes in the texture and appearance of the candy. This thesis investigates the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment. READ MORE

  6. 5. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength

    University essay from KTH/Tillämpad fysik

    Author : Alexandros Bampis; [2023]
    Keywords : Nanophotonics; Quantum Dot Positioning; Photoluminescence Mapping; Scanning Microscope; Nanofotonik; Positionering av kvantprickar; Fotoluminescenskartläggning; Skanningsmikroskop;

    Abstract : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. READ MORE
