  3. 12. Artificial Photosynthesis: Molecular Catalysts for Water Oxidation

    Författare :Lei Wang; Licheng Sun; Hiroshi Imahori; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; artificial photosynthesis; water oxidation; ruthenium complexes; nickel complexes; cerium; photo-catalysts; photosensitizer; electrochemistry; immobilization.; Kemi; Chemistry; Energiteknik; Energy Technology;

    Sammanfattning : Artificial photosynthesis provides a promising solution to the future sustainable energy system. Water is the only suitably sufficient protons and electrons supplier by the reaction of water oxidation. However, this reaction is both kinetically and thermodynamically demanding, leading to a sluggish kinetics unless the introduction of a catalyst. LÄS MER

  4. 13. Passivity & Breakdown of Super Duplex Stainless Steel : Studied with Electrochemical & Synchrotron Techniques

    Författare :Marie Långberg; Jinshan Pan; David Lindell; Ulf Kivisäkk; Edvin Lundgren; Sannakaisa Virtanen; KTH; []
    Nyckelord :Passive film; duplex stainless steel; synchrotron X-ray reflectivity; X-ray diffraction; X-ray fluorescence; hard X-ray Photoelectron emission microscopy; X-ray Photoelectron spectroscopy; Electrochemical impedance; Kemi; Chemistry;

    Sammanfattning : Super duplex stainless steel consists of two phases: austenite and ferrite, and is a highly corrosion resistant material, with a wide range of applications. The corrosion resistance of stainless steels is determined by the performance of a spontaneously formed thin Cr oxide rich film with a thickness of 1-3 nm. LÄS MER

  5. 14. Electrochemical investigations on lipid cubic phases

    Författare :Mohammad Yaser Khani Meynaq; Britta Lindholm-Sethson; Solomon Tesfalidet; Ehud M. Landau; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Monoolein; Electrochemical Impedance Spectroscopy; lipid cubic phase; ionic interaction; biofuel cell; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : Electrochemical Impedance Spectroscopy (EIS) was used to develop a novel methodology for studying ionic interaction with lipids arranged in a lipid cubic phase (LCP). Studying different types of ions, both cations and anions, validated the method. LÄS MER

  7. 15. Artificial Water Splitting: Ruthenium Complexes for Water Oxidation

    Författare :Lele Duan; Licheng Sun; Matthias Beller; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water oxidation; ruthenium; electrochemistry; DFT calculation; photoelectrochemistry; negatively charged ligand; catalyst;

    Sammanfattning : This thesis concerns the development and study of Ru-based water oxidation catalysts (WOCs) which are the essential components for solar energy conversion to fuels. The first chapter gives a general introduction about the field of homogenous water oxidation catalysis, including the catalytic mechanisms and the catalytic activities of some selected WOCs as well as the concerns of catalyst design.
