    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetiska och optiska ; supraledare; magnetisk resonans; egenskaper elektriska; Kondenserade materiens egenskaper:elektronstruktur; supraconductors; magnetic resonance; relaxation; spectroscopy; Condensed matter:electronic structure; electrical; magnetic and optical properties; Kemi; Chemistry; Femtosecond transient absorption; Os-Ru metal ligand complexes; Cu-porphyrin-appended dendrimers; Zn-porphyrin-appended dendrimers; Annihilation; Energy transfer; Solar energy conversion; Artificial photosynthesis; Antenna systems; spektroskopi; Physical chemistry; Fysikalisk kemi; Photochemistry; Fotokemi; Femtosecond fluorescence anisotropy;

    Sammanfattning : A continuing use of fossil fuels will accelerate global warning and result in severe consequences for the environment and thereby also us. Development of alternative, sustainable and environmentally friendly energy sources is therefore crucial. One approach is to create an artificial photosynthetic system that converts sunshine into fuel (e.g. LÄS MER

  5. 4. Doping of Semiconductor Nanowires
