  3. 2. Longterm performance of polyolefins in different environments including chlorinated water: antioxidant consumption and migration and polymer degradation

    Författare :Marie Lundbäck; Ulf Gedde; Thomas Hjertberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; polyethylene; polybutylene; HDPE; LLDPE; phenolic antioxidants; oxidation induction time OIT ; migration; chlorinated water; pressure testing; lifetime; chemical consumption.; Kemiteknik; Chemical engineering; Kemiteknik;

    Sammanfattning : The long-term performance of stabilized polyolefins in different environments was studied with focus on antioxidant consumption and migration. Plaques of linear polyethylene (LPE) and branched polyethylene (BPE) were stabilized with Santonox® R (4,4'-Thiobis(6-tert-butyl-3-methylphenol)), Irganox® 1081 (2,2’-Thiobis(4-methyl-6-tertbutylphenol)), or Lowinox® 22M46 (2,2’-Methylenebis(6-tert-butyl-4-methylphenol)).

  4. 3. The spatiotemporal protein landscape of human cells

    Författare :Lovisa Stenström; Emma Lundberg; Björn Högberg; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Spatial proteomics; Immunofluorescence; Human Protein Atlas; Nucleolus; Cell cycle; Citizen science; Bioteknologi; Biotechnology;

    Sammanfattning : This thesis focuses on the spatiotemporal mapping of proteins at a subcellular level. In other words, determining the cellular location of proteins over time. From a biological point of view, knowledge about protein location is fundamental to understand protein function. LÄS MER

  5. 4. Effect of hydration on thermodynamic, rheological and structural properties of mucin

    Författare :Yana Znamenskaya; Malmö högskola; []
    Nyckelord :mucous gel; mucus; mucin; PGM; BSM; BSM chitosan multilayers; hydration; water sorption isotherm; relative humidity; water activity; bound water; enthalpy of hydration of biopolymer; glass transition; rheology; phase diagram; fiber-like structure; dumbbell-like structure; sorption calorimetry; DSC; QCM-D; SAXS; AFM;

    Sammanfattning : Mucus, an adherent hydrated layer covering the epithelium, is found in all internal tracts of the body and plays an important role in animal and human life. One of the essential functions of mucus is protection of tissues against dehydration. LÄS MER
