  1. 1. Modification of lignin derivatives for polymerization in water

    University essay from KTH/Ytbehandlingsteknik

    Author : Adrian Södergren; [2022]
    Keywords : biobased monomer; ferulic acid; radical polymerization; styrenic mononer; lignocellulose; biobaserad monomer; ferulsyra; radikalpolymerisation; styrenliknande monomer; lignocellulosa;

    Abstract : För att möjliggöra en hållbar utveckling skiftar många polymerforskares fokus just nu från att syntetisera polymerer från fossila resurser till att producera biobaserade polymerer från exempelvis träd. Av särskilt intresse är lignin, som utgör ungefär en tredjedel av allt växtmaterial men i nuläget oftast används som bränsle. READ MORE

  2. 2. Oligosaccharide Analysis - Assessment of the DNS Method and Specification of Glucans Processed with CGTase

    University essay from Lunds universitet/Bioteknik; Lunds universitet/Bioteknik (master)

    Author : Matilda Johansson; [2022]
    Keywords : CGTase; DNS; Chromatography; HPAEC; HPAE; Carbohydrate; Carbohydrates; Glucans; Cyclodextrin glycosyltransferase; Biotechnology; Bioteknik; Flory; Enza; Enzyme; Technology and Engineering;

    Abstract : In this study, the reagent 3,5-dinitrosalicylic acid (DNS) and high-performance anion exchange chromatography (HPAEC) were used for carbohydrate characterisation. It was revealed that the DNS reaction is not exclusive to reducing ends as commonly thought, but rather that the reagent reacts with other parts of the carbohydrate molecules as well. READ MORE

  3. 3. Multiscale numerical approximation of morphology formation in ternary mixtures with evaporation : Discrete and continuum models for high-performance computing

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Author : Mario Setta; [2021]
    Keywords : ;

    Abstract : We propose three models to study morphology formations in interacting ternary mixtures with the evaporation of one component. Our models involve three distinct length scales: microscopic, mesoscopic, and respectively, macroscopic. READ MORE

  4. 4. Novel materials from lignocellulosic sources- can they replace thermoplastics?

    University essay from KTH/Fiber- och polymerteknologi

    Author : Emmy Albinsson; Helina Tafesse Belachew; Jasmin Swaich; Hannah Juhlin; [2021]
    Keywords : Emulisonspolymerisation; Biobaserade plaster; Hållbarhet; Polymerer; Bearbetad halm; Kompositer; PISA-raft;

    Abstract : Plastic waste is a severe environmental problem in today's society which has been noticed and discussed during the last couple of years. A constant increase of production over the last decades hasled to a large amount of plastic waste ending up in oceans as microplastics. READ MORE

  5. 5. Synthesis of a polar conjugated polythiophene for 3D-printing of complex coacervates

    University essay from Linköpings universitet/Laboratoriet för organisk elektronik; Linköpings universitet/Tekniska fakulteten

    Author : Johanna Heimonen; [2021]
    Keywords : conjugated polymers; polythiophene; crosslinking; Suzuki polymerization; OMIEC; complex coacervate; water soluble polymer; Kemi; Kemi;

    Abstract : The aim of this thesis was to synthesize a functionalized polar conjugated polythiophene that could be (3D-) printed into form-stable structures for bio-interfacing. The material design rationale aimed for a water-processable polymer that had the capability of electronic and ionic conduction, by using a thiophene backbone and oligoethylene side chains. READ MORE
