  1. 1. Understanding Composition–Structure–Bioactivity Correlations in Bioactive Glasses

    Författare :Yang Yu; Mattias Edén; Laurent Delevoye; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioactive glasses; Phosphosilicate glasses; Borophosphosilicate glasses; Solid-state NMR spectroscopy; Glass structure; Fourier-transform infrared spectroscopy; Hydroxyapatite; Amorphous calcium phosphate; Apatite formation; In vitro bioactivity testing; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : Bioactive glasses integrate with bone/tooth tissues by forming a layer of hydroxy-carbonate apatite (HCA), which mimics the composition of bone mineral. In the current thesis, we investigated composition–structure–bioactivity correlations of phosphosilicate and borophosphosilicate (BPS) glasses. LÄS MER

    Sammanfattning : This thesis presents an investigation of microscopic structure and electrochemical properties, and their relationship, for various tin-based borate, phosphate and borophosphate glasses. Tin-based glasses have attracted a lot of scientific interest as anode materials in Li-ion batteries. LÄS MER

  4. 3. Ionic Conduction and Bond Valence in Glasses

    Författare :Andreas Hall; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neutron; Phosphate; Borate; reverse Monte Carlo; Glass; Bond Valence; Structure; Diffraction; X-ray; Ion Conduction;

    Sammanfattning : Ion conducting glasses are highly interesting for several different applications, among them, chemical sensors, smart windows with variable optical properties and as electrolytes in batteries. The last example can take full advantage of the ease with which a thin film (... LÄS MER

  7. 5. Investigations of the corrosion resistances of magnetron sputtered multicomponent materials : A study on high entropy alloys, high entropy sublattice ceramics, and metallic glasses

    Författare :Aishwarya Srinath; Leif Nyholm; Ulf Jansson; Rebecka Lindblad; Bernard Normand; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Corrosion resistance; high entropy alloys; magnetron sputtering; thin films; protective coatings;

    Sammanfattning : The corrosion resistances of sputter deposited AlCrNbYZrN, CrNbTiTaWC and TaNiSiC alloys were assessed in acidic and alkaline environments. Compositionally complex alloying strategies, and whether they produced coatings with superior corrosion resistances, were explored. LÄS MER
