  1. 1. Biopolymers processed and used as enzyme carriers

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Dániel Mészáros; [2023]
    Nyckelord :Biobased materials; plasticized sodium alginate; water stability; extraction kinetics; enzyme carrier; Biobaserade material; Mjukgjort natriumalginat; Vattenstabilitet; extraktionskinetik; Enzymbärare;

    Sammanfattning : Syftet med detta masterprojekt var att undersöka möjligheten att använda biobaserat, mjukgjort natriumalginat (NaAlg) som enzymbärare. Alginaterna görs traditionellt bearbetbara genom att tillsätta olika mjukgörare, såsom polyoler (glycerol, sorbitol, etc.), i detta arbete användes glycerol. 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

  4. 3. Optical properties of water absorbing textiles for camouflage

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Eveline Örtenberg; [2023]
    Nyckelord :Camouflage; SWIR; Water; Nanocellulose; CNF; Textiles;

    Sammanfattning : Background matching, a form of camouflage, involves species developing patterns and coloration that closely resemble their environment. Humans have utilized camouflage and background matching, particularly in military applications, to reduce detectable characteristics, known as signatures. LÄS MER

  5. 4. Processing techniques of perovskite solar cells : Properties depending on material and manufacturing

    Kandidat-uppsats, Uppsala universitet/Fysikalisk kemi

    Författare :Andréa Nordmark; Simon Nilsson; [2023]
    Nyckelord :;

    Sammanfattning : This project investigates how different types of perovskite solar cells, differentiated by choice of materials and processing techniques, compares to each other regarding performance and characterization. The purpose of the project is to further develop perovskite solar cells and to improve the method of manufacturing for better performance. LÄS MER

  7. 5. Topical formulation of antimicrobials for wound care

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för farmaceutisk biovetenskap

    Författare :Ida Cederwall; [2022]
    Nyckelord :topical formulation; antibiotic resistance; topical antimicrobial formulation; topical gel; AMP; AP114; amoxicillin; wound care; poloxamer; HPMC;

    Sammanfattning : The increasing spread of antibiotic resistance among bacteria poses a major threat to the public health. There is an urge for the development of innovative formulations of existing and new antibiotics. LÄS MER
