  1. 1. Functional Bio-based Copolyesters: Properties and Abilities

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Fika Andriani; [2022]
    Nyckelord :Ring-opening copolymerization; epoxide; anhydride; crosslinked; degradation; Ringöppningssampolymerisation; epoxid; anhydrid; tvärbundet; nedbrytning;

    Sammanfattning : Genom ringöppningssampolymerisation av utvalda epoxider och anhydrider möjliggjordes en enkel strategi för att syntetisera funktionella sampolymerer. Sampolymererna hade förmågan att bilda tvärbundna material, och var dessutom benägna för både hydrolytisk och enzymatisk nedbrytning. LÄS MER

    Sammanfattning : Three-dimensional (3D) printing has an important role for fabrication of degradable scaffoldsfor soft tissue regeneration. Among the 3D printing techniques, photopolymerization-based 3Dprinting is one of fastest growing, offering environmental benefits and high precision of 3Dobjects. LÄS MER

  4. 3. Photoredox catalysis with 10-phenyl-10H- phenothiazine and synthesis of a photocatalytic chiral proline-based organocatalyst

    Master-uppsats, KTH/Organisk kemi

    Författare :Panagiotis Lamprianidis; [2020]
    Nyckelord :organic chemistry; photocatalysis; organocatalysis; organocatalyst; organic synthesis; organisk kemi; fotokatalys; organokatalys; organokatalysator; organisk syntes;

    Sammanfattning : Photoredox catalysis applications for the purpose of new synthetic routes in organic and sustainable chemistry are hot topics in organic synthesis today. In the present study, the synthesis of a chiral proline-based organocatalyst functionalized with 10-phenyl-10H phenothiazine (PTH) photocatalytic moietiesis investigated and attempted for the first time.
