  1. 6. Electron transport in microbial chlorate respiration

    Författare :Anna Smedja Bäcklund; Thomas Nilsson; Åke Strid; Karlstads universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; c cytochromes; chlorate reduction; electron transport; c cytokromer; kloratreduktion; elektrontransport; Biochemistry; Biokemi; Kemi; Chemistry;

    Sammanfattning : Several bacterial species are capable to use perchlorate and/or chlorate as an alternative electron acceptor in absence of oxygen. Microbial respiration of oxochlorates is important for biotreatment of effluent from industries where oxochlorates are produced or handled. LÄS MER

  4. 8. Influence of Bridge Structures on the Electron Transfer in Donor-Acceptor Systems

    Författare :Mikael Winters; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular wire; electron transfer; porphyrin; conjugated oligomer;

    Sammanfattning : In this Thesis, porphyrin-based donor-acceptor systems have been used to study photoinduced electron transfer processes. Principally, two different sets of systems have been investigated. LÄS MER

  5. 9. Bridge Mediated Electron Transfer in Conjugated and Cross-Conjugated Donor-Acceptor Compounds

    Författare :Erik Göransson; Leif Hammarström; Hans-Christian Becker; Michael R. Wasielewski; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron transfer; Ultrafast; Long-range; Intervalence charge transfer; cross conjugation; hyperconjugation; Physical Chemistry; Fysikalisk kemi;

    Sammanfattning : Detailed understanding of electron transfer reactions is important in many aspects of chemistry, biology and solar energy conversion.The main aim of this thesis is to provide further insight into electron transfer through highly conjugated bridge structures. LÄS MER

  7. 10. Electron Donor Systems in Natural and Artificial Photosynthesis

    Författare :Ann Magnuson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; solar energy; artificial photosynthesis; Photosystem II; EPR; Biology; Biologi;

    Sammanfattning : Photosynthesis is the process by which light energy is converted into chemical products, in photoautotrophic bacteria, algae and plants. The principal idea is the production of reducing agents by photo-induced oxidation of a sacrificial electron donor. LÄS MER
