  1. 1. 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

    Nyckelord :Skin health; Absorbent pad; Smart responsive materials; Textile sensors; chromic materials; pH indicator; Halochromic dyes; Sol-gel coating; TEOS; GPTMS; PET; PP; and Nonwovens;

    Sammanfattning : Incontinence diapers or disposable absorbent pads provide essential help to people having such a physical difficulty. However, during prolonged used of these products in daily life, the skin inside pad area may get fragile and damaged which are difficult to recover in old ages. LÄS MER

  5. 4. Coating fine particles

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för kemi - Ångström

    Författare :Bergqvist Andrea; [2014]
    Nyckelord :;

    Sammanfattning : Controlled release of an active is used in many applications. An example is drug delivery were it is desirable to release the active substance close to the target. In paints can anti-mold substances be encapsulated and released slowly during a long time which can extend the lifetime of the paint. LÄS MER

  7. 5. PROCESSUTVECKLING FÖR JÄRNBASERADE HÅRDMAGNETISKA PULVER UTAN SÄLLSYNTA JORDARTSMETALLER

    Master-uppsats, Lunds universitet/Materialteknik

    Författare :Per-Olof Andersson; [2014]
    Nyckelord :Crystalline metals; Magnetic materials; Hard magnetic materials; Electro-magnetic applications; Single crystalline powder; Powder metallurgy; Fe2B; FeB; Water atomization; Gas Water atomization; non-RE hard magnetic material.; Technology and Engineering;

    Sammanfattning : An experimental study was performed, aimed at finding a way to produce single crystalline powder of pure (Fe0.7Co0.3)2B with a particle size of 100-200nm. This was done with the ultimate goal of producing a hard magnetic ferrite powder for powder metallurgical production of permanent magnets. LÄS MER
