  1. 1. Chemical modification of starch in order to get thermoplastic properties

    University essay from KTH/Materialvetenskap

    Author : Emma Hallbert; Elsa Wadman; [2023]
    Keywords : thermoplastic starch; dialdehyde starch; schiff-base; imine chemistry; termoplastisk stärkelse; dialdehydstärkelse; schiffbas; iminkemi;

    Abstract : There are numerous advantages of replacing traditional non-biodegradable synthetic plastics with bio-based plastics. Starch is globally available, cheap, renewable, and biodegradable. However, starch has a poor product performance and is relatively difficult to process, as conventional melt processing techniques cannot be used. READ MORE

  3. 2. Knockout of transcription factor MYB28 by CRISPR/Cas9 for reducing glucosinolate content in rapeseed (Brassica napus L.)

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Anusha Harshani Bogahawatta; [2023]
    Keywords : CRISPR Cas9; Glucosinolates; ; MYB28; protoplast; ; rapeseed; ; ribonucleoprotein; ; transcription factor;

    Abstract : Rapeseed cake is a protein-rich by-product from the rapeseed oil extraction process. It contains high levels of glucosinolates (GSLs), which possess anti-nutritional functions after being hydrolyzed. Moreover, the hydrolyzed products of GSLs produce an extremely bitter taste.

  4. 3. Lignin Biorefining: Swelling and activation of fibers for lignin extraction

    University essay from KTH/Fiber- och polymerteknologi

    Author : Ali Al Husseinat; [2023]
    Keywords : Biorefining; Carboxymethylation; Extraction; Lignin; Swelling; Bioraffinering; Extraktion; Karboxymetylering; Lignin; Svällning;

    Abstract : I världens omvandling mot en bioekonomi kommer lignocellulosa material spela en stor roll i ersättningen av fossila resurser. Lignin är den mest tillgängliga källan av förnybara och naturligt förekommande aromatiska ämne och den utgör 15–30% av ved. READ MORE

  5. 4. Ethylene to Liquid Hydrocarbons by Heterogeneously Catalyzed Oligomerization on ZSM-5

    University essay from Uppsala universitet/Fysikalisk kemi

    Author : Gustav Halldén; [2022]
    Keywords : ethylene; ethane; oligomerization; catalyst; heterogeneous catalysis ZSM-5; zeolite;

    Abstract : The aim is to produce aliphatic liquid hydrocarbons using heterogeneous ethylene oligomerization. Thiscould potentially produce renewable synthetic fuels. Heterogeneous catalysis has some advantages overhomogeneous catalysis regarding some sustainability aspects. READ MORE

  6. 5. Technical Lignin Characterization of Acacia crassicarpa and Eucalyptus Hybrids

    University essay from KTH/Träkemi och massateknologi

    Author : Lutfi Difi Rosta; [2021]
    Keywords : Lignin; Acacia crassicarpa; Eucalyptus Hybrids; kraft cooking; kraft dissolving pulp cooking; Lignin; Acacia crassicarpa; Eucalyptus Hybrids; kraftkokning; kraftupplösning av massa;

    Abstract : Lignin är en av de vanligaste naturliga råvarorna på jorden och finns mestadels i trä. Nuförtiden är valoriseringen av lignin en av processutvecklingarna för teknologier inom massa- och pappersindustrin. Denna utveckling syftar till att öka värdet av lignin. READ MORE
