  1. 1. Thermal Conversion of Cellulose-Lignin Precursors into Carbon Fibres

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Sofia Westberg; [2023]
    Nyckelord :Carbon fiber; lignin; cellulose; continuous conversion;

    Sammanfattning : Carbon fibres are used in many applications thanks to their exceptional tensile properties in relation to their relatively low weight. These thin strands of at least 90% carbon are mixed with a matrix such as epoxy to form composites used for cars, wind turbines, prosthetics, and many other things. LÄS MER

  3. 2. Building performance optimisation tools for the decarbonisation of Swedish buildings

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

    Författare :Nadja Baden; Marziyeh Taghizadeh; [2023]
    Nyckelord :Optimisation; Parametric design; Decarbonisation; Renovation; Technology and Engineering;

    Sammanfattning : To mitigate climate change and reach Sweden’s goal of becoming carbon neutral by 2045, or at an earlier stage of 2030 for 23 Swedish cities, urgent action is required to reduce greenhouse gas emissions. Due to the building sector’s significant contribution to carbon emissions, a crucial aspect in achieving these goals is improving the energy efficiency of existing buildings, as most of these will still be in use by this time.

  4. 3. The Influence of Pigment Additives on the Barrier Properties of Dispersion Coatings

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Malin Eriksson; [2022]
    Nyckelord :dispersion coating; paper products; pigment; sustainable development; circular economy; Dispersionsbarriär; pappersprodukter; pigment; hållbar utveckling; cirkulär ekonomi;

    Sammanfattning : Att minska plastavfall och uppmuntra återvinning har fått hög prioritet i många affärsverksamheter och olika typer av regleringar implementeras för att minska den negativa påverkan av plastanvändningen. Papper och kartong består i huvudsak av cellulosa som har många egenskaper som är essentiella för en hållbar ekonomi (t.ex. LÄS MER

  5. 4. Fibre content in moose (Alces alces) faeces : a comparison between free-ranging and captive moose in Sweden

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Ada Trapp; [2022]
    Nyckelord :diarrhoea; zoo; browser; ruminant; Alces alces;

    Sammanfattning : Animals have evolved adaptations to survive and reproduce in certain environments. Based on these adaptations, different feeding types can be identified among ruminants from the continuum of browsers to grazers. Browsers are assumed to digest forage rich in soluble cell contents, while grazers are more equipped to digest cellulose. LÄS MER

  7. 5. Investigation of the binding effect of fungal fiber (grown on apple pomace) in the formation of lyocell nonwoven textiles and their potential applications

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

    Författare :Xue Luo; [2021]
    Nyckelord :lyocell; nonwovens; binder; filamentous fungi; wet-laid; fungal microfibers; apple pomace; cellulose;

    Sammanfattning : This project combines nonwoven technology, biological technology and food waste management and seeks for this feasibility to use fungal microfiber (FM) as a binder for lyocell pro-duction and the characterizations for possible applications. Rhizopus delemar was cultivated apple pomace in liquid-state fermentation to obtain mycelia biomass. LÄS MER
