  2. 1. Surface-Induced Modification of Supported Late Transition Metal Complexes

    Author : Olesia Snezhkova; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; N-heterocyclic carbene palladium complexes; X-ray photoelectron spectroscopy; electron charge transfer; iron phthalocyanine; catalysis; X-ray absorption spectroscopy;

    Abstract : The work presented in this thesis addresses the investigation of the electronic, magnetic, and structural properties of late transition metal complexes supported on various surfaces. The research is aimed at studying the interaction between the molecules and the support, together with the intermolecular interaction. This knowledge is essential e.g. READ MORE

  4. 2. Crystallography in Four Dimensions : Methods and Applications

    Author : Gunilla Carlsson; Janos Hajdu; Dieter Oesterhelt; Vilmos Fülöp; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biophysics; horseradish peroxidase; redox reactions; X-ray crystallography; haem catalysis; molecular movies; radiation damage; Molekylär biofysik; Molecular biophysics; Molekylär biofysik;

    Abstract : The four-electron reduction of dioxygen to water is the most exothermic non-photochemical reaction available to biology. A detailed molecular description of this reaction is needed to understand oxygen-based redox processes. Horseradish peroxidase (HRP) is a haem-containing redox enzyme capable of catalysing the reduction of dioxygen to water. READ MORE

  5. 3. Structural Plasticity and Function in Cytochrome cd1 Nitrite Reductase

    Author : Tove Sjögren; Christian Cambillau; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; cytochrome cd1; nitrite reductase; oxidase; redox protein; electron transfer; proton transfer; X-ray crystallography; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Cytochrome cd1 nitrite reductase is a bifunctional enzyme, which catalyses the one-electron reduction of nitrite to nitric oxide, and the four-electron reduction of oxygen to water. The latter is a cytochrome oxidase reaction. Both reactions occur on the d1 haem iron of the enzyme. READ MORE
