  1. 21. Model Systems for Metal - DNA Interactions. With a Focus on Anticancer Active Platinum(II) Complexes

    Författare :Anna Ericson; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kinetics; DNA; poly d T ; guanine; 6-thioinosine-5 -monophosphate; 6-thio-2 -deoxyinosine; 4-thiouridine-5 -monophosphate; 4-thio-2 -deoxyuridine; palladium II ; Gold III ; platinum II ; mechanism; salt effect; activation parameters; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : Reactions of trans-dicyanodichloroaurate(III) trans-dibromodicyanoaurate(III), trans-diamminedichlorogold(III), cis-diammine(aqua)chloroplatinum(II), cis-ammineaqua-(cyclohexylamine)chloroplatinum(II), chloro(terpyridine)platinum(II) and chloro-(diethylenetriaminepalldium(II) with dimethyl sulfide, thionucleosides, thionucleotides and thione- and guanine-containing 17-mer oligonucleotides have been investigated by use of conventional and high-pressure stopped-flow spectrophotometry and HPLC technique as a function of ionic strength, pH, temperature and pressure in aqueous solutions. The mechanism and rate of oxidation of dimethyl sulfide by gold(III) complexes depends on the concentration of free halide. LÄS MER

  3. 22. On the Thermodynamic Solvation of Biomolecules in Solution

    Författare :Stefan Hervö Hansen; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solubility; Solvation; Aggregation; Statistical thermodynamics; Molecular dynamics; Monte Carlo simulations; Free energy calculations; Energy-representation theory of solvation; Proteins; Salt bridges; Caffeine;

    Sammanfattning : The topic solvation thermodynamics is an important aspect of chemistry, dealing with the effects introduced by solvents onto solutes. In particular, biological systems are highly heterogeneous in their choice of solvent typically characterized by either being in a polar or non-polar environment. LÄS MER

  4. 23. Ocean Climate Variability over Recent Centuries Explored by Modelling the Baltic Sea

    Författare :Daniel Hansson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; ocean climate; modelling; reconsstruction; water temperature; sea ice; river runoff; salinity; oxygen concentration; long-term;

    Sammanfattning : Natural variability and anthropogenic factors both contribute to changes in the ocean climate of the Baltic Sea. Observations over the past century indicate that changes in environmental settings and ocean climate have taken place, attracting considerable media attention and building public awareness of climate and environmental issues related to the Baltic Sea.

  5. 24. Anisotropic Protein Interactions in Salt Solutions and at Interfaces: Coarse Grained Modeling

    Författare :Anil Kurut Sabanoglu; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Anisotropic interactions; protein electrostatics; phase association; surface adsorption; coarse grained models; Monte Carlo simulations;

    Sammanfattning : Anisotropic protein interactions have a strong orientation dependence resulting from an uneven distribution of charged and hydrophobic residues on the protein surface. They play an important role in protein behaviors such as protein association, surface adsorption and phase separation. LÄS MER

  7. 25. Innovative process solutions towards recycling of salt cake from secondary aluminum smelting

    Författare :Peng Li; Lidong Teng; Sankaran Subramanian; KTH; []
