  4. 19. Evolution of artificial defects during shape rolling

    Författare :Mirjana Filipovic; Stefan Jonsson; Per-Olov Perä; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shape rolling; wire rod rolling; artificial defects; defect evolution; surface cracks; porosity; FEM; high speed steel; stainless steel; Other materials science; Övrig teknisk materialvetenskap; Initiering och utveckling av defekter under spårvalsning;

    Sammanfattning : Very often defects are present in rolled products. For wire rods, defects are very deleterious since the wire rods are generally used directly in various applications. For this reason, the market nowadays requires wire rods to be completely defect-free. Any wire with defects must be rejected as scrap which is very costly for the production mill. LÄS MER

  5. 20. 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
