  1. 1. Analys av transparent trä tillverkat genom delignifiering och PMMA-infiltration

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Hannah Rosell; Tove Tisell Mikkelsen; Nadiya Wattar; Selma Kadric; [2023]
    Nyckelord :Transparent wood; fiber technology; polymer infiltration; delignification; wood chemistry;

    Sammanfattning : Rapporten presenterar en studie där tre trätyper, balsa, ask och björk, fabriceras genom en förutbestämd metod till transparent trä. Detta material har många möjliga applikationer, inklusive energieffektiva byggnader, förpackningar, solceller och elektroniska apparater. LÄS MER

  3. 2. 3D printing of ceramic composites with improved mechanical strength

    Master-uppsats, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Liu Yuchen; [2023]
    Nyckelord :;

    Sammanfattning : AbstractCeramic materials have a wide range of applications in many fields, but their fragility limits theiruse in high strength and high stress environments. Therefore, by combining ceramic materialswith reinforcing agents, their mechanical properties can be improved. LÄS MER

  4. 3. Block copolymer-based hybrid nanomaterials for nanoimprint applications

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska Högskola

    Författare :Philip Sellin; [2022]
    Nyckelord :Block copolymer; Sequential infiltration synthesis; Nanoimprint lithography; Reactive ion etching; Self-assembly; Thermal annealing; Solvent vapour annealing; Nanoprocessing; Nanofabrication; Antibacterial; Technology and Engineering;

    Sammanfattning : In this Master’s thesis project, a block copolymer (BCP) film was used in combination with sequential infiltration synthesis and etching to manufacture a nanoimprint lithography stamp consisting of silicon. The BCP film was designed to contain perpendicularly aligned hexagonally placed cylinders, a pattern that will later be investigated for antibacterial properties after being transferred via nanoimprint lithography to a polymer film.
