  1. 36. Development Of Bio-Based Thermosetting Resins

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

    Author : Snehaben Gaurangkumar Mistry; [2021]
    Keywords : Bio-based polymer; Resin; lactide; lactone; isosorbide; butanediol; polymerisation; characterisation; FTIR; NMR; TGA; DMA;

    Abstract : Thermoset polymers are widely used polymers in the world, but Increase in global plastic pollution and lack of fossil fuel stimulates intense research towards environmentally sustainable materials. Bio-based unsaturated polyesters (UPs) would be an excellent solution to replace oil-based synthetic polyesters. READ MORE

  4. 38. Ancient plant cuticle chemistry: preservation and characterization of organic matter as biomarker of past UV-B radiation

    University essay from KTH/Kemi

    Author : Larissa Lopes Cavalcante; [2021]
    Keywords : UACs; fossil cuticle; p-coumaric acid; ferulic acid; UV-B proxy; micro-FTIR; confocal Raman microscope; UAF; fossil kutikula; p-kumarinsyra; ferulinsyra; UV-B-proxy; mikro-FTIR; konfokalt Raman-mikroskop;

    Abstract : Biologiska processer hos olika organismer påverkas av ultraviolett-B-strålning (UV-B). Kunskapen om förändringar i UV-B-flödet som nått planetens yta under det geologiska tidsspann sedan flercelligt liv uppstod är dock begränsad. READ MORE

  5. 39. Dispersed bio-based binders as drop-in solution for non-woven industry

    University essay from KTH/Fiber- och polymerteknologi

    Author : Emma Ingo; [2021]
    Keywords : Dispersion; Modified Biopolymers; Non-Woven; Binders; Green Chemistry; Dispersion; Modifierade Biopolymerer; Non-Woven; Bindemedel; Grön Kemi;

    Abstract : Sammanfattning på svenska: Målet med projektet var att utveckla ett system av disperserade bindemedel för non-wovenindustrin som inte förutsätter omfattande förändringar i befintliga processer. Bindemedlet ska vara biobaserat, bionedbrytbart och endast bestå av byggstenar som är matkontaktsgodkända av FDA och BFR. READ MORE

  6. 40. Spruce bark biorefinery

    University essay from KTH/Fiber- och polymerteknologi

    Author : Leon Ahlström; Rebecca Mattsson; Hampus Eurén; Alicia Lidén; [2021]
    Keywords : Norway spruce bark; bark biorefinery; extractives; cellulose; lignin; non-cellulose; polysaccharides; soxhlet extraction; hot-water extraction; organosolv extraction; PAA; delignification; carbohydrate analysis; 2D HSQC-NMR and FTIR; Granbark; bark bioraffinaderi; lignin; organosolv extraktion; hot-water extraktion;

    Abstract : Spruce Bark contains several fundamental main substances; lignin, non-cellulose polysaccharides, cellulose and extractives. This undergraduate study focuses on developing a process to extract each of these components from spruce bark using a biorefinery concept, with a main focus on extracting lignin without degradation.
