  1. 1. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines

    Master-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Shivang Parmar; [2023]
    Nyckelord :Environmental barrier coating; ceramic matric composite; atmospheric plasma spray; suspension plasma spray; thermal cyclic fatigue; Barriärbeläggning; keramisk komposit; atmosfärisk plasmasprutning; suspensionsplasmasprutning; termisk cyklisk utmattning;

    Sammanfattning : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. LÄS MER

  2. 2. Sargassum digestate as fertiliser in Grenada

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Lina Bengtsson; Theodor Halldin; [2023]
    Nyckelord :Sargassum; digestate; fertiliser; heavy metals; Sargassum; digestat; gödningsmedel; tungmetaller;

    Sammanfattning : Surges of Sargassum have become more severe and at the time of writing the largest surge yet is set to hit the Caribbean islands, affecting tourism and marine life negatively. Tourism is Grenada’s single handedly largest economic sector, which is why it is important to research the use of Sargassum. LÄS MER

  3. 3. A Circular Solution for Plastic Waste Within Healthcare : A fully implementable solution for creating a circular end-of-life option for plastic waste using chemical recycling

    Master-uppsats, KTH/Produktionsutveckling

    Författare :Bharghav Ganesh; Iliass Temsamani; [2023]
    Nyckelord :;

    Sammanfattning : With a growing awareness of the environmental impacts associated with the disposal of healthcare plastic consumables through conventional end-of-life methods, such as landfilling and incineration, there is an increasing need to adopt more sustainable practices. This thesis explores the development of an alternative, circular economy-based solution to manage plastic waste generated by the healthcare sector, focusing on the identification of circular end-of-life strategies.
