    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neighbor interaction; spectroscopy; diastereomeric; kinetics; antimicrobial activity; ruthenium; calorimetry; intercalation; DNA; enantiomer;

    Sammanfattning : Organic molecules, such as glucose and amino acids, are most often chiral. This means that their mirror-images are different, in the same way a left and a right hand are different from each other. For example, the DNA double helix in its standard form twists like a right-handed screw. LÄS MER

  4. 14. Structural Requirements for Selective DNA Binding - Studies on Mono- and Binuclear Ruthenium Complexes

    Författare :Johanna Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ruthenium; enantioselectivity; sequence selectivity; spectroscopy; threading intercalation; calorimetry; kinetics; DNA; cell studies;

    Sammanfattning : Ever since the discovery of the role of DNA as the template for protein synthesis, efforts have been made to develop DNA targeted drugs. One of the major challenges in the design of DNA binding drugs is to achieve selective binding to specific DNA sequences, which is crucial to avoid side effects. LÄS MER

  5. 15. Development of Ruthenium Catalysts for Water Oxidation

    Författare :Tanja M. Laine; Björn Åkermark; Antoni Llobet; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; homogeneous catalysis; O-O bond formation; photocatalysis; ruthenium; water oxidation; organisk kemi; Organic Chemistry;

    Sammanfattning : An increasing global energy demand requires alternative fuel sources. A promising method is artificial photosynthesis. Although, the artificial processes are different from the natural photosynthetic process, the basic principles are the same, i.e. LÄS MER
