  1. 1. GRAPHENE MODIFIED E-TEXTILE : AN INDUSTRY RELEVANT APPROACH OF DOPING AND VISUALISING A FULLY TEXTILE P-N JUNCTION DIODES

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

    Författare :Bilel Meskini; [2023]
    Nyckelord :E-textile; viscose; polyester; graphene; graphene oxide GO; reduced graphene oxide rGO; tannic acid; plasma treatment; electrochemical deposition; doping; semiconductor;

    Sammanfattning : As a wonder material, graphene has been studied in various applications due to its exceptional properties. Recently it has been used in textile to obtain functionalised garments as E-textile. From an industry-relevant perspective, it is essential to introduce a process that could be scaled-up. LÄS MER

  3. 2. Production of textile fibres from filamentous fungi grown on apple pomace : invertase pre-treatment

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Sofia Berg; [2023]
    Nyckelord :apple pomace; invertase; fibres; filamentous fungi; dry gel spinning;

    Sammanfattning : In this work Rhizopus Delemar was grown on an apple pomace medium, a waste product from the juice industry. The apple pomace was pre-treated with the enzyme invertase to hydrolyse the sucrose available in the waste to glucose and fructose, which are digestible by the fungus. LÄS MER

  4. 3. Urea-Based Treatments of Unretted Hemp Fibres from Residual Streams

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

    Författare :Danilo Esteban Ortiz Sarasty; [2023]
    Nyckelord :Finola waste; stalks; unretted hemp fibres; degumming; cold urea alkali; microwave-urea;

    Sammanfattning : More sustainable and efficient degumming methods are required to extract finner bast fibres, especially from agro-industrial waste streams such as stalks from hemp for food purposes. For this reason, in this study, two urea-based treatments were evaluated as degumming alternatives for unretted hemp fibres from residual streams, one at cold and alkaline conditions (CUA) and the other in combination with microwave radiation (MWU).

  5. 4. Fractionation of Wheat Bran for Utilisation in Biorefinery

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Gabriella Haag; [2021]
    Nyckelord :Wheat bran; biorefinery; chemical engineering; vetekli; bioraffinaderi; extraction; Technology and Engineering;

    Sammanfattning : Wheat bran is a by-product from the production of wheat flour. Nowadays wheat bran is mostly used as feed for animals, in the food and baking industry or it is simply burned in open air. LÄS MER

  7. 5. Film formation of mixed-halide perovskites for PSCs

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Lina Ekstedt; [2021]
    Nyckelord :Mixed Halide Perovskites; Perovskite Solar Cells; Bandgap Tuning; In-situ Spectroscopy; Antisolvent; Interface Modifier.; Physics and Astronomy;

    Sammanfattning : Over the last few years there has been a steady increase in interest in the exploration of perovskite materials within photovoltaic research. This can to a large extent be attributed to the incredible pace at which solar cells based on perovskites have improved in efficiency during the same time period. LÄS MER
