  1. 6. Characterization methodology to assess the mechanical properties of delignified birch/PMMA transparent wood biocomposites

    University essay from KTH/Fiber- och polymerteknologi

    Author : Nicolò Arcieri; [2022]
    Keywords : Transparent wood; mechanical properties; fracture toughness; in situ experiments; cohesive zone model; Transparent trä; mekaniska egenskaper; brottsstyrka; in situ-experiment; modell för kohesionszonen;

    Abstract : Transparent trä biokompositer (TW) är en ny attraktiv klass av biokomposit. De är uppbyggda av delignifierat trä som impregnerats med en polymer med matchande brytningsindexet.  TW kan skräddarsys för inom ett brett spektrum av funktionella, optiska och mekaniska egenskaper.

  3. 7. Enhancement of translucence in fiber-based packaging materials

    University essay from KTH/Fiber- och polymerteknologi

    Author : Saila Tallinen; [2022]
    Keywords : Paper; translucent; fiber-based packages; impregnation; cellulose; papper; genomskinlighet; fiberbaserade förpackningsmaterial; impregnering; cellulosa;

    Abstract : The utilization of fiber-based packages has started to take more place at the packaging sector but is still restricted by a lack of transparency. Today this challenge is tried to be solved by paying more attention on the characteristics of nanofibers and their possibilities. READ MORE

  4. 8. Long-term Effect of Metallic Iron Sorbents on Arsenic Mobility in an Anoxic Aquifer : An assessment based on long-term column experiments

    University essay from SLU/Dept. of Soil and Environment

    Author : Stéphanie Nyström; [2022]
    Keywords : Zero valent iron; ZVI; Remediation; Anoxic; Column tests; ICP-MS;

    Abstract : Zero valent iron (ZVI) sorbents have successfully remediated soils burdened with different groups of contaminants. When working to alleviate arsenic (As) contamination, the location-specific subsurface chemistry greatly affects the efficiency of the sorbents as it controls the speciation of As and the transformation of the ZVI, as well as the interaction between these (remediating mechanisms).

  5. 9. The effectivity of vacuum impregnation with glycerol and secondary metabolites on electroporated arugula leaves to improve freezing stability.

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

    Author : Oscar de Kuijer; [2021]
    Keywords : Pulsed electric field PEF; Arugula; Electroporation; Secondary metabolites; Glycerol; Food engineering; Livsmedelsteknik; Technology and Engineering; Agriculture and Food Sciences;

    Abstract : Freeze damage is a common issue in many food items. The cellular dehydration caused by freezing can be prevented through addition of a cryoprotectant. Research has shown that it is possible to improve the freezing tolerance of plant materials by addition of cryoprotectants, which forms hydrogen bonds with water molecules. READ MORE

  6. 10. Effects of Vacuum Impregnation with Various Substances in Combination with Pulsed Electric Field to Improve the Freezing Tolerance of Arugula Leaves

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

    Author : George Lukhava; [2021]
    Keywords : Food Engineering; Food Preservation; Pulsed Electric Fields; PEF; Vacuum Impregnation; VI; Arugula; Cryoptrotectant; Glycerol; Secondary Metabolites; Folic Acid; Folate; Folacin; Vitamin B1; Thiamine; Thiamin; Agriculture and Food Sciences;

    Abstract : As of 2020 an estimated number of 821 million people across the world are undernourished and that figure is expected to grow by 2 billion before the end of 2050 (United Nations Sustainable Development 2020). Despite this, every year over 1/3 of food produced globally is disposed of without consumption (Global Panel on Agriculture and Food Systems for Nutrition 2018), and the actual number might be much higher.
