  1. 1. Biopolymers processed and used as enzyme carriers

    University essay from KTH/Fiber- och polymerteknologi

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

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Solcellsteknik

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

    Abstract : 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. READ MORE

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

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Eveline Örtenberg; [2023]
    Keywords : Camouflage; SWIR; Water; Nanocellulose; CNF; Textiles;

    Abstract : 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. READ MORE

  5. 4. 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.

  6. 5. Quantitative and qualitative analysis of dyes in pulp from recycled textiles

    University essay from KTH/Fiber- och polymerteknologi

    Author : Anna Bevin; [2023]
    Keywords : Textile fibers; Dyes; Kappa number; FTIR; UV-VIS; Textilfibrer; Färgämnen; Kappatal; FTIR; UV-VIS;

    Abstract : To decrease the environmental footprint, the textile industry needs to become more circular. One company that is trying to close the textile lifecycle loop is the Swedish company Renewcell. In the Renewcell process, discarded clothes and other textile waste are turned into a dissolving pulp that can be used for production of new textiles. READ MORE
