  1. 1. Iron, Manganese and Iridium Complexes From Models of RNR and Catalase to Water Oxidation

    Författare :Michele Bedin; Anders Dr. Thapper; Sascha Prof. Ott; Vadim G. Kessler; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Iron; manganese; MnCAT; RNR; biomimetic; Kemi; Chemistry;

    Sammanfattning : The focus of this thesis has been synthesise and study metal complexes that mimic the structure and function of the active site in two particular metalloenzymes, ribonucleotide reductase (RNR) and manganese catalase (MnCAT). These two metalloenzymes both have two transition metals ions in the cofactor: two manganese ions in MnCAT and either two iron, iron-manganese or two manganese ions in RNR. LÄS MER

  3. 2. Design of new materials with crystal structure-related properties : The role of lone pair cations

    Författare :Eleni Mitoudi Vagourdi; Mats Johnsson; Vadim Kessler; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Crystal structure determination; New oxohalide compounds; Lone-pair electrons; X-ray diffraction; Physical properties; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Non-centrosymmetry and low-dimensional arrangements, e.g. chains or layers, are very attractive structural characteristics of crystalline compounds since they are linked to some physical properties including nonlinear optical activity, ferroelectricity and magnetic frustration.
