  2. 1. Water film-mediated mineralogical transformations and photocatalytic reactions

    Author : N. Tan Luong; Jean-Francois Boily; Michael Holmboe; Alejandro Fernandez-Martinez; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; mineral; water films; carbon dioxide; MgO; MnCO3; TiO2; hydroxylation; carbonation; oxidation; transformation; photocatalysis; Inorganic Chemistry; oorganisk kemi; nanomaterials; nanomaterial; Physical Chemistry; fysikalisk kemi;

    Abstract : Mineral particles capture water vapor in the atmosphere in the form of water films that are only few monolayers thick. Water films form nanoscale hydration environments that mediate a wide range of important reactions in nature and technology. READ MORE

  4. 2. Structure-Property Relationships of Iron N-Heterocyclic Carbene Complexes : Synthesis, Characterization and Application

    Author : Valtýr Freyr Hlynsson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; photoredox catalysis; photovoltaics; photosensitizer; N-heterocyclic carbene NHC ; BHAS; synthesis; Organometallic chemistry; structure-property relationship; coordination chemistry; heteroleptic iron complexes; geometry; photophysics;

    Abstract : Resulting from the general availability of first-row transition metals, compared to their second- and third-row counterparts, photosensitizers (PSs) based on metals like iron have gained interest as candidates to enable photochemistry from solar energy, a largely underutilized energy source. Iron complexes equivalent to other metal complexes, currently being used as PS, do lack some of the advantageous properties required to challenge the established PSs. READ MORE

  6. 4. Nitrogen-containing products from atmospheric oxidation of volatile organic compounds

    Author : Epameinondas Tsiligiannis; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; VOC; anthropogenic; biogenic; SOA; atmospheric oxidation; organic aerosols; CIMS; FIGAERO; TMB; isoprene; HOM; organonitrates ONs ; NOx; OH; nitrate NO3 ; Go:PAM; SAPHIR;

    Abstract : Atmospheric oxidation of volatile organic compounds (VOC) produces a wide range of oxygenated organic products that lead to formation of secondary organic aerosol (SOA). SOA represents a significant fraction of the tropospheric aerosol that influence climate and human health. READ MORE

  7. 5. Applications of Molecular Dynamics in Atmospheric and Solution Chemistry

    Author : Xin Li; Hans Ågren; Ari Laaksonen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical chemistry; Teoretisk kemi;

    Abstract : This thesis focuses on the applications of molecular dynamics simulation techniques in the fields of solution chemistry and atmospheric chemistry. The work behind the thesis takes account of the fast development of computer hardware, which has made computationally intensive simulations become more and more popular in disciplines like pharmacy, biology and materials science.
