    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Vilma Hurtigh Grabe; [2023]
    Keywords : bonding; micro system; glass frit; sealing; finite element; modeling; glass; mikrosystem; sammanfogning; glasfog; fog; finita element; modellering; glas;

    Abstract : PureFize Technologies AB develops and manufactures a broadband ultraviolet (UVC) light technology device that is mercury-free and based on nanotechnology, using the principle of field emission. The light source is made of Ti and glass, which are hermetically bonded, using a low-temperature glass frit, at elevated temperatures. READ MORE

  3. 2. The development of an acoustic insulation solution using mushroom mycelium as an alternative to synthetic foams

    University essay from Jönköping University/JTH, Industridesign

    Author : Adrián Brito Guerrero de Escalante; [2023]
    Keywords : mycelium composites; design thinking; design for emotion; sustainability; acoustic insulation; fungi; mushrooms.;

    Abstract : In the past decades, humanity is facing the consequences of the irresponsible production of plastics and the expansion of industries such as industrial agriculture, Therefore, the development of new sustainable alternative materials has become increasingly popular as a science field. That is the case of mycelium composites, a biodegradable material made out of agricultural and the thread-like roots of mushrooms called mycelium. READ MORE
