  1. 1. Sustainable food packaging based on polyhydroxyalkanoate

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

    Författare :Safana Al-Ashor; [2024]
    Nyckelord :Biopolymers; Sustainable food packaging; Circular economy; Biobased and biodegradable materials; Food packaging; Processing technologies; Food quality; Shelf-life;

    Sammanfattning : The Norwegian Food Research Institute (Nofima) and the University of Borås worked together to develop this project. The commonly used packaging materials pose a serious threat to the environment, as they are produced from nonrenewable crude oil and cannot decompose naturally. LÄS MER

  3. 2. Wavelength-dependent limb darkeningin the analysis oftransit spectroscopy of exoplanets

    L3-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Alberto García Ribas; [2023]
    Nyckelord :;

    Sammanfattning : Limb darkening, an optical effect characteristic of stars, where the limb (edge) seemsto be darker than the centre of the stellar body; plays an important role in our under-standing of exoplanetary transits, as it is fundamental for developing light curve modelsthat can help to undercover extrasolar companions. To recover atmospheric featuresfrom exoplanets, a principal component analysis method is typically used. LÄS MER

  4. 3. James Webb Space Telescope Observations of Jupiter’s Moon Europa

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

    Författare :Aulon Nura; Isac Engblom; [2023]
    Nyckelord :;

    Sammanfattning : The creation of life has puzzled humanity since the dawn of time. With the launch of thecutting-edge James Webb Space Telescope (JWST) at last year's closing, the next step in humanity'ssearch for life has been taken. LÄS MER

  5. 4. FTIR mätningar av absorptionsvätskor i Bioenergy Carbon Capture and Storage processer

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Isa Pettersson Haag; Emma Hedberg; Oliver Svahn; David Danielsen; [2023]
    Nyckelord :BECCS; FTIR; carbon dioxide; carbonate; bicarbonate; PCA;

    Sammanfattning : The effects of global warming are well understood. In order to combat this, society must move towards net zero emissions of green house gases, where carbon dioxide (CO2) plays a key role. In several IPCC climate scenarios that meet the Paris agreement, negative emission technologies that effectively remove CO2 from the atmosphere are included. LÄS MER

  7. 5. Using the James Webb Space Telescope to Find Carbon Dioxide on Ganymede

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

    Författare :Olof Helgesson; Oscar Lundin; [2023]
    Nyckelord :;

    Sammanfattning : The aim of this bachelor's thesis is to search for CO₂ on Ganymede by studyingobservations taken by the James Webb Space Telescope and in doing so, create aprocessing pipeline for JWST data. The data is collected by JWST's Near InfraredSpectrograph instrument which is used for spectroscopy in the near infrared spectrum. LÄS MER
