  1. 1. An Ion-Selective Electrode for Detection of Ammonium in Wastewater Treatment Plants

    Master-uppsats, KTH/Kemi

    Författare :Josephine Berg; [2021]
    Nyckelord :jonselektiv elektrod; membran; ammonium; sensor; reningsverk; ion-selective electrode ISE ; membrane; ammonium; sensor; wastewater treatment plant WWTP ;

    Sammanfattning : Att följa ammonium i reningsverk är avgörande för att förbättra reningsprocessen och kontrollera flödet av föroreningar ut till ekosystemet. Jonselektiva elektroder (ion-selective electrodes, ISEs) är en lovande teknik inom området, där polymermembran baserade på nonactin är de mest studerade membranen för ammoniumsensorer. LÄS MER

  2. 2. 3D printing of alginates into tubular structures resembling human airways

    Sammanfattning : Tissue shortage for lung transplantation remains a problem worldwide as lung transplantation is often the only available option with numerous possible complications. Generating lung tissue ex-vivo has been proposed as one way to potentially overcome this shortage. LÄS MER

  3. 3. The Development Of Bio-Composite Films From Orange Waste : A Methodological And Evaluation Study Of Material Properties

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

    Författare :Samira Syed; [2021]
    Nyckelord :Orange waste; bio-composite films; biodegradable; glycerol; citric acid; ultrafine grinder film casting;

    Sammanfattning : Bioplastic research has become more diverse and different types of research on bioplastic production have been conducted from fruits and vegetable waste, for example, orange waste. The wastes that come from oranges contain more than just vitamins, it has soluble sugars, starch, hemicellulose, cellulose, and pectin. LÄS MER

  4. 4. Compound meniscus implant prototypes : Bench test performance of knitted casing to contain, fixate and mechanically stabilize cell seeded gels

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

    Författare :Maria Ydrefors; [2021]
    Nyckelord :Knitting technology; meniscus replacement; hydrogel; Artelon®; bioprinting; biomechanical properties;

    Sammanfattning : Meniscal tears are the most common intra-articular injury of the knee joint. Due to the avascular zone with limited blood supply, treatment of the injury is a complex process. Today, research on the development of efficient treatments and meniscal replacements is of increasing interest. LÄS MER

  5. 5. Evaluation of Wet Spinning of Fungal and Shellfish Chitosan for Medical Applications

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

    Författare :Ghasem Mohammadkhani; [2021]
    Nyckelord :Chitosan fiber; Fungal fiber; Wet spinning; Hydrogel; Suture applications;

    Sammanfattning : The aim of this project was to address the food waste problem, particularly bread waste, to some extent by producing monofilaments obtained from wet spinning of fungal hydrogel through the cultivation of Rhizopus delemar on bread waste. The project had two phases. LÄS MER
