  1. 1. Surface functionalization of cellulose fibers and exploration of its influence in ion exchange chromatography

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Anna Wessén; [2023]
    Nyckelord :Ion-exchange chromatography; membrane chromatography; surface extension; grafting; copolymerization; free-radical polymerization; Jonbyteskromatografi; membrankromatografi; ytförlängning; ympning; sampolymerisation; fri radikal polymerisation;

    Sammanfattning : Kromatografiska metoder kan användas för en mängd olika tillämpningar, inklusive separation, rening och analys av biomolekyler och kemikalier. Membrankromatografi är en av de nya kromatografiteknikerna som expanderar snabbt eftersom den tillåter hög masstransport genom den stationära fasen, vilket resulterar i en mer tidseffektiv process.

  3. 2. Synthesis and characterization of a greener poly(vinyl acetate) adhesive

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Xiuting Zhang; [2023]
    Nyckelord :poly vinyl acetate -grafted-chitosan; chitosan; poly vinyl acetate ; ceric ammonium nitrate; green adhesive; poly vinyl acetat -ympad kitosan; poly vinyl acetat ; ceriumammoniumnitrat CAN ; grönt lim;

    Sammanfattning : To produce a greener adhesive is always an issue of concern to the commercial market and global environment. The environmental request for producing greener and bio-based adhesives leads to an increased awareness of replacing fossil-based components in adhesives with bio-based alternatives. LÄS MER

  4. 3. Sustainable Polymer Production: Investigating Synthesis and Copolymerization of Cyclic Ketene Acetals

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Soufian Bourraman; Stella Staffas; Adam Brandt; Simon Isaksson; [2023]
    Nyckelord :Monomers; polymers; radical; radical ring opening polymerization; polymerization; BMDO; MMA; MVL; MBL; comonomer; copolymer; rROP; sustainable; biobased; degradable; monomer synthesis; plastic; polyester; bulk; solution; NMR; FTIR; TGA; DSC; SEC; hydrolysis; molecular weight; diol; ester bonds;

    Sammanfattning : The large amount of non-degradable plastic waste has become a significant environmental concern, leading to an increased need for degradable plastics. Here in, to create degradable polymers, polyesters were produced through radical ring opening polymerization using cyclic ketene acetals. LÄS MER

  5. 4. Effect of DNAJB6 on α-synuclein amyloid fibril aggregation and dis-aggregation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Biofysikalisk kemi

    Författare :Josef Getachew; [2023]
    Nyckelord :α-synuclein; alpha-synuclein; chaperones; DNAJB6; the unhappy chaperone; parkinsons disease; biophysical chemistry; biochemistry; Biology and Life Sciences; Chemistry; Technology and Engineering;

    Sammanfattning : Amyloid proteins are a group of proteins with the ability to form large fibrillar aggregates, identifiable by their cross-β core structure. These aggregates are linked to several different neurodegenerative diseases such as Parkinson’s disease and Alzheimer’s disease and due to the growing rate of people diagnosed, there is a need to combat these diseases.
