  1. 1. Lanthanide Metal-Organic Frameworks and Hierarchical Porous Zeolitic Imidazolate Frameworks : Synthesis, Properties, and Applications

    Författare :Hani Nasser Abdelhamid; Xiaodong Zou; Belén Martín-Matute; Banglin Chen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metal-organic frameworks; Zeolitic imidazolate frameworks; Lanthanide MOFs; Hierarchical porous ZIFs; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : This thesis presents the synthesis, properties, and applications of two important classes of metal-organic frameworks (MOFs); lanthanide MOFs and hierarchical porous zeolitic imidazolate frameworks (ZIFs). The materials have been characterized using a wide range of techniques including diffraction, imaging, various spectroscopic techniques, gas sorption, dynamical light scattering (DLS) and thermogravimetric analysis (TGA).

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nb-based sulfides; misfit layered; structure determination; electron diffraction; Chemistry; Kemi;

    Sammanfattning : In this work we have investigated the intercalation of electron-donors between NbS2 slabs in Nb-based layer sulfides.Two series of Sr substituted Nb-based misfit sulfides belonging to the 1.5Q/1H and 1Q/1H series of misfit layer compounds have been synthesised. LÄS MER

  4. 3. Novel Route of Oxynitride Glass Synthesis and Characterisation of Glasses in the Ln-Si-O-N and Ln-Si-Al-O-N Systems

    Författare :Abbas Saeed Hakeem; Saeid Esmaeilzadeh; Jekabs Grins; Thommy Ekström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : The present work has been primarily focused on the glass forming region in the La-Si-O-N system, and attempts have been made to find glass forming regions by adopting a new synthesis route to produce glasses in oxynitride system. This goal can be attained by adding a network modifier in its metallic form instead of as an oxide. LÄS MER
