  2. 2. Biomimetic Reactions Water Oxidation and Aerobic Oxidation

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Lien-Hoa Tran; Björn Åkermark; Nina Kann; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cobalt II salophen; oxygen-activating catalyst; hybrid; manganese complex; epoxidation; water oxidation.; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi; Organic Chemistry; organisk kemi;

    Abstract : This thesis deals mainly with two oxidation reactions: water oxidation and aerobic oxidation, both of which have been applied in a biomimetic fashion. In the former reaction molecular oxygen is generated whereas in the latter it was used as terminal oxidant in oxidation reactions. READ MORE

  3. 3. Single Copper Nanoparticle Oxidation

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Sara Nilsson; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dark-field scattering spectroscopy; single particle; plasmonic nanospectroscopy; plasmonic sensing; transmission electron microscopy; oxidation; nanoscale Kirkendall effect;

    Abstract : Cu nanoparticles are commonly used in microelectronic devices and as catalysts in, for example, methanol synthesis and methanol steam reforming reactions. However, Cu nanoparticles are prone to oxidation. READ MORE

  4. 4. Internal oxidation processing New alloys and new simulation techniques

    University dissertation from Stockholm : KTH

    Author : Henrik Larsson; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internal oxidation; nitriding; diffusion; simulation; random walk; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Nitriding and oxidising treatments of alloys for toolingpurposes have been investigated both experimentally andtheoretically. Specimens prepared by a combination of differentprocessing steps are investigated by light-optical, scanningand transmission electron microscopy and hardness measurments. READ MORE

  5. 5. Photosynthetic water oxidation the function of two extrinsic proteins

    University dissertation from Umeå : Fysiologisk botanik

    Author : Tatiana Shutova; Göran Samuelsson; Stenbjörn Styring; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photosystem II; Psb0; Cah3; water oxidation; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi;

    Abstract : The solar energy accumulated by photosynthesis over billions of years is the sole source of energy available on Earth. Photosystem II (PSII) uses the sunlight to split water, an energetically unfavorable reaction where electrons and protons are extracted from water and oxygen is released as a by-product. READ MORE
