  1. 1. Characterisation of Poly(trimethylene carbonate) and f-BTI2g-TVTCN blends for the use in Biosensors

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Sara El Ghamri; Ed Kammeby; Herman Göransson; Arvid Stjerngren; [2023]
    Nyckelord :Bionedbrytbara biosensorer; Biodegradable biosenors; Organic mixed ionic–electronic conductors; Carboxyl esterase; organic electrochemical transistors; poly trimethylene carbonate ;

    Sammanfattning : This report aims to study the degradation of poly(trimethylene carbonate) (PTMC) caused by the enzyme carboxylesterase in vitro. As well as to characterise polymer blends of f-BTI2g-TVTCN and poly(3-hydroxybutyric acid) as core components for organic electrochemical transistors (OETCs). LÄS MER

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Moa Eklund; Amanda Olofsson Ribrant; [2023]
    Nyckelord :Digital Light Processing 3D Printing DLP ; Additive manufacturing; Bio-based; Polymer; Thermosets; Covalent Adaptable Networks CANs ; Recycling; Characterization.; Digital Light Processing 3D Printing DLP ; Additiv tillverkning; Bio-baserad; Polymer; Härdplast; Kovalenta Anpassningsbara Nätverk CANs ; Återvinning; Karaktärisering.;

    Sammanfattning : Thermosets are appropriate materials for various applications due to benefits such as heat resistance and good mechanical properties. The disadvantages of traditional thermosets from a sustainable manufacturing perspective are that they are usually derived from fossil resources, and also have permanent cross-linked networks that are difficult to break, making them non-recyclable.

  4. 3. Produktion av polyhydroxialkanoater (PHA) med Bacillus megaterium

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Shahdokht Arab Goueini; [2021]
    Nyckelord :Bacillus megaterium; biopolymerer; polyhydroxialkanoater; polyhydroxibutyrat;

    Sammanfattning : Plastproduktionen och användningen av plast ökar varje år i hela världen och detta är ett av världens största problem. Plaster är ett svårnedbrytbart ämne och processen kan ta hundratals år. Detta leder i sin tur till att plastackumuleringen orsakar skadlig påverkan på klimat, miljö och människor. LÄS MER

  5. 4. Engineering Rhodosporidium toruloides for the production of polyhydroxybutyrate

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Tova Lindh; [2021]
    Nyckelord :Applied microbiology; Bioplastics; Rhodosporidium toruloides; Polyhydroxybutyrate; Non-conventional yeast; Oleaginous yeast; Biology and Life Sciences;

    Sammanfattning : The increased use of plastics has become an environmental problem where plastics, due to the slow degradation, accumulate in the oceans and landfills. Although plastics are a very cheap and useful material with desirable properties and a wide variety of applications, they are primarily made from petroleum-based resources which are non-renewable and of fossil origin.

  7. 5. BICONTINUOUS MACROPOROUS MATERIALS FROM EPOXY RESIN-BASED MONOLITHS

    Master-uppsats, Umeå universitet/Kemiska institutionen

    Författare :Thuy Trân Ho-Thi; [2021]
    Nyckelord :;

    Sammanfattning : In this project, hydrophilic bicontinuous microporous materials were synthesized via one‑pot polycondensation, using epoxy compounds and polyamines as the main monomer and curing agents. To achieve this goal, two approaches have been taken. LÄS MER
