4. 3. 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

5. 4. Protein Nanomaterials: : Functionalization, Self-assembly, and Applications

   Författare :Lei Wang; Niclas Solin; Olle Inganäs; German Salazar-Alvarez; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : As one of the major classes of materials that is relevant to biological function of our daily life, proteins are highly interesting in both biological and material science. Self-assembled protein amyloid nanostructures have been considered not only as aggregates in pathological tissue, but also as a kind of advanced one dimension materials in material science perspective due to their favorable characteristics including high aspect ratio, abundant surface charge groups, high stability, and tunable surface properties.
