  1. 1. Exploring functionalization of colloidal silica for nanoparticle-stabilized emulsions

    Författare :Sanna Björkegren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; thermo-responsive emulsions; functionalized colloidal silica; Pickering emulsions; NMR spectroscopy; surface activity; clouding;

    Sammanfattning : The main objective of this thesis was to evaluate how surface functionalized colloidal silica can be utilized in emulsions stabilized solely by particles, so called Pickering emulsions. To achieve this, water-dispersed silica nanoparticles were functionalized with hydrophilic and hydrophobic groups. LÄS MER

    Författare :Benyam Estifanos; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fe-Ti oxide; hercynite; siderite; stilpnomelane; olivine corona; Swedish Caledonides; hysteresis; PIXE; synchrotron XRD; Rietveld; microprobe; red corundum; palaeomagnetism; eclogite; plagioclase clouding; dolerite; pyroxene gneiss; Geology; physical geography; Geologi; fysisk geografi;

    Sammanfattning : This thesis consists of four subprojects: (A) ‘Clouding of plagioclase by Fe-Ti oxides’, (B) ‘Fe-Ti oxides during high-pressure metamorphism of mafic rocks’, (C) ‘Magnetic study of Fe-Ti oxides in mafic rocks and metabasites’, and (D) ‘Topotactic phase transitions in oxide minerals’. A) In southern Sweden dolerite dikes and gabbros with clouded plagioclase are common. LÄS MER

  5. 4. Enzyme Hydrolysis of Cellulose Derivatives. Active Site Studies and Polymer Characterisation

    Författare :Herje Schagerlöf; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; Humicola insolens; Trichoderma reesei; Bacillus agaradhaerens; Mass spectrometry; Substituent distribution; Characterisation; Endoglucanases; Cellulose derivatives;

    Sammanfattning : Soluble derivatives of cellulose have become increasingly important in industrial products e.g. in pharmaceutical applications and in technical dispersions. The polymer characteristics of modified celluloses are to a high degree determined by the substituent distribution along the polymeric backbone. LÄS MER

  7. 5. Public Planning, Neoliberal Hybridity and Local Activism in Sundbyberg : Epochal Reconfiguration of Urban Development in Greater Stockholm

    Författare :Christoffer Berg; Susanne Urban; Fredrik Palm; Miguel A. Martínez; Christian Schmid; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Neoliberalism; neoliberal urbanism; urban planning; urban development; production of space; Henri Lefebvre;

    Sammanfattning : Which urban policy responses are deployed when a small social democratic municipality in a greater city region aims to be competitive for private investments in housing and the built environment? Which new institutional development arrangements are implemented for this purpose, in the wake of a decades-long hegemonic position of the municipal public housing company? This thesis draws on a qualitative case study design to approach such questions, and investigates recent urban development in Sundbybergs stad in Greater Stockholm to answer them. Theoretically, the thesis draws on a theory of neoliberal localization in combination with Henri Lefebvre’s theory of the social production of space. LÄS MER
