    Sammanfattning : The polymer electrolyte fuel cell converts the chemical energy in a fuel, e.g. hydrogen or methanol, and oxygen into electrical energy. The high efficiency and the possibility to use fuel from renewable sources make them attractive as energy converters in future sustainable energy systems. LÄS MER

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

    Detta är en avhandling från Umeå : Fysiologisk botanik

    Författare :Tatiana Shutova; Umeå universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photosystem II; Psb0; Cah3; water oxidation; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi;

    Sammanfattning : 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. LÄS MER

  5. 5. Hydrogen Storage Materials Design, Catalysis, Thermodynamics, Structure and Optics

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Carlos Moysés Graça Araújo; Uppsala universitet.; [2008]
    Nyckelord :Materials science; Hydrogen-storage materials; Density functional theory; Molecular dynamics; Catalysis; Thermodynamics; Optics; Materialvetenskap;

    Sammanfattning : Hydrogen is abundant, uniformly distributed throughout the Earth's surface and its oxidation product (water) is environmentally benign. Owing to these features, it is considered as an ideal synthetic fuel for a new world energetic matrix (renewable, secure and environmentally friendly) that could allow a sustainable future development.
