  1. 1. Inkjet printed piezoelectric energy harvesters based on self-assembly of diphenylalanine peptide

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Yujie Fu; [2023]
    Nyckelord :Inkjet printing; piezoelectric energy harvester; diphenylalanine peptide; self-assembly; Bläckstråleutskrift; piezoelektrisk energiskördare; difenylalaninpeptid; självmontering;

    Sammanfattning : Diphenylalanine peptide (Phe-Phe or FF) is a very promising bio-material in the future wearable electronics application due to its self-assembly into nanotubes and nanoribbons with high shear piezoelectric coefficient which is comparable to traditional inorganic piezoelectric materials. In order to efficiently harvest piezoelectric response, alignment and unidirectional polarization of FF nanotubes are required. LÄS MER

  3. 2. Multifunctional ice and snow repellent coatings for photovoltaic modules

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Solcellsteknik

    Författare :Gunnar Sandkvist; [2023]
    Nyckelord :sol-gel; superhydrophobic; dip-coating; anti-reflective; silica;

    Sammanfattning : Implementation of solar power by photovoltaic modules in cold climates, such as northern Sweden, implies several challenges. Ice and snow coverage not only leads to reduction in energy production due to shading, but it also puts equipment at risk from additional weight. LÄS MER

  5. 4. 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.

  7. 5. Frontier materials at the air-liquid interface: Self-assembly of green ionic liquids

    Kandidat-uppsats, KTH/Yt- och korrosionsvetenskap

    Författare :Ulrika Karlson; Morgan Ölander; Fernando Zevallos; [2021]
    Nyckelord :Ionic liquids; Green chemistry; X-ray reflectivity; AIR-liquid interface; Self assembly; Jonvätskor; Grön kemi; Självorganisation;

    Sammanfattning : The interfacial structuring of three non-halogenated ionic liquids was examined at the air-liquid interface for both dry and humid condition by analysis of X-ray reflectometry data using a slab model approach. The aim was to investigate the effect of humidity on the air-liquid interface. LÄS MER
