  4. 8. 3D printing of ceramic composites with improved mechanical strength

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Liu Yuchen; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

  5. 9. Water purification of ibuprofen using whey protein aerogels with and without PNF-structure

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Jessica Lyrner Morén; David Jonsson; [2023]
    Keywords : Aerogels; water purification; ibuprofen; protein nanofibrils PNF ; whey protein; attitudes; scientific research; Aerogeler; vattenrening; ibuprofen; protein nanofibriller PNF ; vassleprotein; attityder; naturvetenskaplig forskning;

    Abstract : Clean water, free from pharmaceuticals, is important both for land and water living animals. Protein nanofibrils (PNFs) have already been shown to be a promising candidate for water purification of pharmaceuticals but there is a lack of research that compares PNF materials to non-PNF protein materials for water purification.
