  2. 11. Towards Conduction Band Mediated Multi-electron Transfer: Spectroscopic Studies of Photosensitizer-semiconductor-acceptor Assemblies

    Author : Elin Sundin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Solar fuels; charge separation; dye-sensitized; semiconductor thin films; electron transfer;

    Abstract : Converting solar energy into a storable form in chemical bonds, i.e., generating solar fuels, is a promising strategy for producing renewable fuels. This however comes with several challenges that need to be solved before generation of solar fuels can become a reality. READ MORE

  4. 12. Synthesis of Covalently Linked Diporphyrins: Model Compounds for Intramolecular Energy and Electron Transfer

    Author : Johan Kajanus; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; donor-bridge-acceptor systems; Sonogashira reaction; electron transfer; porphyrin; palladium; model compound; energy transfer;

    Abstract : Three series of donor-bridge-acceptor compounds have been synthesized to probe the influence of various bridge chromophores on energy and electron transfer. The donor-bridge-acceptor compounds in each series comprise two different porphyrins, acting as donor and acceptor, covalently linked by bridge chromophores. READ MORE

  5. 13. Porphyrin-Based Donor-Bridge-Acceptor Systems: Intrinsic Excited State Deactivation and Intramolecular Energy/Electron Transfer Reactions

    Author : Joakim Andreasson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spectroscopy; superexchange; mediation; energy transfer; porphyrins; conformational gating; conformational distortions; electron transfer;

    Abstract : Intramolecular energy and electron transfer reactions have been studied between porphyrin donor and acceptor moieties. The porphyrin units are covalently linked together by one of three different bridging chromophores to constitute the series of D-B-A systems. READ MORE

  6. 14. c Cytochromes as Electron Carriers in Microbial Chlorate Respiration

    Author : Anna Smedja Bäcklund; Thomas Nilsson; Pia Ädelroth; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; c cytochrome; chlorate reduction; electron transport; Biochemistry; Biokemi; Kemi; Chemistry;

    Abstract : Microbial respiration of oxochlorates is important for the biotreatment of effluents from industries where oxochlorates are produced or handled. Several bacterial species are capable to use perchlorate and/or chlorate as an alternative electron acceptor in absence of oxygen. READ MORE

  7. 15. Electron tomography and optical modelling for organic solar cells

    Author : Viktor Andersson; Olle Inganäs; Joachim Loos; Linköpings universitet; []
    Keywords : Organic solar cells; Electron tomography; Optical modelling;

    Abstract : Organic solar cells using carbon based materials have the potential to deliver cheap solar electricity. The aim is to be able to produce solar cells with common printing techniques on flexible substrates, and as organic materials can be made soluble in various solvents, they are well adapted to such techniques.
