  1. 11. Molecular Structure, Interfacial Chain Topology, Electronic Structure and Fracture Toughness of Polyethylene: A Multiscale Computational Study

    Författare :Ali Moyassari Sardehaei; Ulf W. Gedde; Gregory C. Rutledge; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The structure of semicrystalline polyethylene (PE) strongly affects its properties. Two important structural features, namely the concentrations of tie chains and entanglements cannot be directly assessed using experimental techniques. LÄS MER

  3. 12. Heterogeneous Degradation and Recyclability of PP Studied by Imaging Chemiluminescence

    Författare :Mikael Hamskog; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Teknik; Technological sciences; recyclability; mapping; surface; heterogeneity; heterogeneous; evaporation; ageing; hamamatsu; russel; ICL; CL; Irganox 1010; Irganox 1076; oxidation; hydroperoxide; radical; carbonyl; luminescence; chemiluminescence; imaging chemiluminescence; recycling; stabilization; polypropylene; degradation;

    Sammanfattning : Oxidative degradation is a serious threat to long-term use and recyclability of polymers. Successful recycling of polymeric quality products requires characterization of the polymer material after reprocessing and use. LÄS MER

  4. 13. Competitive adsorption of macromolecules during emulsification

    Författare :Lars Nilsson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technological sciences; Egg yolk proteins; Competitiva adsorption; Field Flow Fractionation; Hydrophobically modified starch; Emulsions;

    Sammanfattning : The adsorption behavior of macromolecular emulsifiers is important in the understanding of their functionality. Understanding of the adsorption behavior can ultimately enable us to control emulsion properties. LÄS MER

  5. 14. On the Aggregation of Cereal β-Glucan and its Association with other Biomolecules : A Study using Asymmetric Flow Field-Flow Fractionation (AF4)

    Författare :Claudia Zielke; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :ß-glucan; polysaccharides; dietary fiber; field flow fractionation; Asymmetric flow field-flow fractionation AF4 ; Multiangle light scattering MALS ;

    Sammanfattning : During recent years, numerous studies have shown the ability of dietary fiber toprotect the colon from disease and to improve intestinal health. Beneficial healtheffects, such as the lowering of blood cholesterol levels and a reduction in the risk of coronary heart disease, are often directly related to cereal β-glucan, one of the major components of dietary fiber found in oat and barley.

  7. 15. Formation and Transformation of Atmospheric Brown Carbon (BrC)

    Författare :Kalyan Mitra; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; brown carbon BrC ; primary organic aerosol POA ; secondary organic aerosol SOA ; BrC bleaching; BrC browning; Toluene photo-oxidation; NOx; Ammonia; NH3; acidity effects; light absorption;

    Sammanfattning : Atmospheric brown carbon (BrC) aerosol absorbs light in the UV-Vis spectrum and has poorly constrained but potentially large climate forcing impacts. Most current climate models lack detailed chemistry and interlinked properties of atmospheric BrC, that induce large uncertainties in radiative forcing predictions. LÄS MER
