  1. 11. Ruthenium(II) Polypyridyl Complexes : Applications in Artificial Photosynthesis

    Författare :Olof Johansson; Licheng Sun; Björn Åkermark; Michael D Ward; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Chemistry; Kemi;

    Sammanfattning : Molecular mimics of PS II, which consist of a photosensitizer linked to electron acceptors/donors, are attractive candidates for the conversion of solar energy into chemical energy. Several different classes of sensitizers have been studied and among these, ruthenium(II) polypyridyl complexes continue to attract major attention. LÄS MER

  3. 12. Simplicial Complexes of Graphs

    Författare :Jakob Jonsson; Anders Björner; John Shareshian; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Algebra and geometry; simplicial complex; monotone graph property; discrete Morse theory; simplicial homology; homotopy type; connectivity degree; Cohen-Macaulay complex; Euler characteristic; decision tree; Algebra och geometri; Algebra and geometry; Algebra och geometri;

    Sammanfattning : Let G be a finite graph with vertex set V and edge set E. A graph complex on G is an abstract simplicial complex consisting of subsets of E. In particular, we may interpret such a complex as a family of subgraphs of G. LÄS MER

  7. 15. Electrical Properties of Gold-related Defect Complexes in Silicon

    Författare :Einar Sveinbjörnsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DLTS; gettering; Au in Si; lithium diffusion; Au-H complexes; Au-Li complexes; deep levels; phosphorus diffusion; hydrogen in silicon;

    Sammanfattning : This thesis describes three extensive experiments concerning the properties of gold as an impurity atom in crystalline silicon. The first study is an investigation of the effect of phosphorus diffusion on the distribution of gold atoms within a silicon crystal. LÄS MER
