  1. 11. Investigation of Antenna Radomes in Low Earth Orbits

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Mathias Manohar Gren; [2023]
    Keywords : Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

    Abstract : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

  3. 12. DRY POWDER FOR INHALATION - INFLUENCE OF MIXING PROCESS AND ADDITION OF MAGNESIUM STEARATE

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

    Author : Love Ivarsson; [2023]
    Keywords : inhalation; drug delivery; pulmonary drug delivery; API; FPF; FPD; DD; Turbula; Diosna; mixing energy; mixing time; mixing speed; pharmaceutical technology; Medicine and Health Sciences;

    Abstract : For efficient treatment of many diseases of the lung, it is beneficial to deliver the medicine to the respiratory tract directly. This ensures a rapid response since it can enter the bloodstream directly through the alveolar epithelium. Consequently, also decreases systemic effects due to the local treatment. READ MORE

  4. 13. Investigation on the natural indigo dye for cotton fabric by using supercritical carbon dioxide

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

    Author : Ryoi Takamatsu; [2023]
    Keywords : Dyeing; supercritical carbon dioxide; indigo; cotton; eco-friendly; textile;

    Abstract : Concerns about the environmental impact of the textile industry are increasing, and there is an urgent need to develop and implement sustainable technologies. In particular, the environmental impact of dyeing, which emits a large amount of wastewater and chemicals, is one production process that needs to be resolved. READ MORE

  5. 14. WEAR RESISTANT MULTI FUNCTIONAL POLYMER COATINGS

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Pranay Kumar Parsi; [2023]
    Keywords : Polymer coatings; Materials; Tribology; Wear resistant; Ice adhesion; Freezing delay; Anti-icing de-icing;

    Abstract : This study aims to develop coatings which show wear resistant behaviour along with multiple functions such as improved ice adhesion, better freezing delay etc which help in improving the effectiveness of the wind turbine efficiency. The significance of anti-icing/de-icing solutions for wind turbines is emphasized since ice accretion can cause serious issues in generation of power and might lead to damage of blades. READ MORE

  6. 15. Crystallinity of Sputtered TiO2 Thin Films: a Study of the Heating and Plasma Influence on the Growth

    University essay from

    Author : oussama ezzaher; [2023]
    Keywords : ;

    Abstract : AbstractHigh-Power Impulse Magnetron Sputtering (HIPIMS) of TiO2 thin films enhances their photocatalyticproperties compared to the films prepared by standard sputtering methods, especially when no substrateheating is employed. With no heating, the coatings present an amorphous structure that benefits from theionization of the sputtered flux granted by HiPIMS, with respect to their photocatalytic performance. READ MORE
