  1. 1. Biopolymers processed and used as enzyme carriers

    University essay from KTH/Fiber- och polymerteknologi

    Author : Dániel Mészáros; [2023]
    Keywords : Biobased materials; plasticized sodium alginate; water stability; extraction kinetics; enzyme carrier; Biobaserade material; Mjukgjort natriumalginat; Vattenstabilitet; extraktionskinetik; Enzymbärare;

    Abstract : Syftet med detta masterprojekt var att undersöka möjligheten att använda biobaserat, mjukgjort natriumalginat (NaAlg) som enzymbärare. Alginaterna görs traditionellt bearbetbara genom att tillsätta olika mjukgörare, såsom polyoler (glycerol, sorbitol, etc.), i detta arbete användes glycerol. READ MORE

  3. 2. Incorporation of Plasticizers through Refining into Wood Pulp : A Potential Route For Bio-based Thermoplastic Materials

    University essay from KTH/Materialvetenskap

    Author : Victor Eric Pierre Chartrain; [2023]
    Keywords : Cellulose; Paper; Plasticizer; Mechanical Refining; Cellulosa; Papper; Mjukgörare; mekanisk bearbetning;

    Abstract : Fibers are interesting materials alternative to replace conventional fossil-based plastics, as they are bio-based and do not lead to CO2 emissions. Due to their limited ductility, it is difficult to use them to make complex three-dimensional shapes. READ MORE

  4. 3. Lifetime prediction of a polymeric propellant binder using the Arrhenius approach

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Johannes Bohlin; [2021]
    Keywords : Polymer; Thermal-oxidative degradation; Lifetime prediction; Propellant; Arrhenius; Aging experiments; Diffusion-limited oxidation;

    Abstract : The thermal-oxidative degradation of a crosslinked hydroxy-terminated polybutadiene (HTPB)/cycloaliphatic diisocyanate (H12MDI) based polymer, which is commonly used as a polymeric binder in propellants, is investigated at temperatures from 95°C to 125°C with the aim of estimating the lifetime of the material in storage conditions (20°C) using the Arrhenius approach. Furthermore, the effect of antioxidants and to a lesser extent plasticizer on the degradation process was also studied. READ MORE

  5. 4. An Ion-Selective Electrode for Detection of Ammonium in Wastewater Treatment Plants

    University essay from KTH/Kemi

    Author : Josephine Berg; [2021]
    Keywords : jonselektiv elektrod; membran; ammonium; sensor; reningsverk; ion-selective electrode ISE ; membrane; ammonium; sensor; wastewater treatment plant WWTP ;

    Abstract : Att följa ammonium i reningsverk är avgörande för att förbättra reningsprocessen och kontrollera flödet av föroreningar ut till ekosystemet. Jonselektiva elektroder (ion-selective electrodes, ISEs) är en lovande teknik inom området, där polymermembran baserade på nonactin är de mest studerade membranen för ammoniumsensorer. READ MORE

  6. 5. The Development Of Bio-Composite Films From Orange Waste : A Methodological And Evaluation Study Of Material Properties

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Samira Syed; [2021]
    Keywords : Orange waste; bio-composite films; biodegradable; glycerol; citric acid; ultrafine grinder film casting;

    Abstract : Bioplastic research has become more diverse and different types of research on bioplastic production have been conducted from fruits and vegetable waste, for example, orange waste. The wastes that come from oranges contain more than just vitamins, it has soluble sugars, starch, hemicellulose, cellulose, and pectin. READ MORE
