1. 16. 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

3. 17. Catalytic partial oxidation of methane over nickel and ruthenium based catalysts for GTL applications

   Författare :Jorge A. Velasco; Magali Boutonnet; Sven Järås; Henrik Kusar; Stan Kolaczkowski; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Catalytic partial oxidation; carbon formation; GTL; nickel; ruthenium; synthesis gas; thermodynamic equilibrium.; Chemical Engineering; Kemiteknik;

   Sammanfattning : The Gas to Liquids (GTL) process is an important alternative for monetizing natural gas through the production of long-chain liquid hydrocarbons, e.g. diesel fuel. LÄS MER

4. 18. Nanoscaled Structures in Ruthenium Dioxide Coatings

   Författare :Christine Malmgren; Håkan Olin; Joakim Bäckström; Mittuniversitetet; []
   Nyckelord :Bleaching chemicals; sodium chlorate; ruthenium dioxide; electrodes; crystallites; nanowires; microscopy; diffraction; electrocatalytic area; reduced energy consumption; NATURAL SCIENCES; NATURVETENSKAP;

   Sammanfattning : An essential ingredient in the generation of environmentally compatible pulp bleaching chemicals is sodium chlorate. Chlorate is produced in electrochemical cells, where the electrodes are the key components. In Sweden the so-called DSA !R electrodes with catalytic coatings have been produced for more than 35 years. LÄS MER

5. 19. Ruthenium(II) Polypyridyl Complexes : Applications in Artificial Photosynthesis

   Författare :Olof Johansson; Licheng Sun; Björn Åkermark; Michael D Ward; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organisk kemi; Chemistry; Kemi;

   Sammanfattning : Molecular mimics of PS II, which consist of a photosensitizer linked to electron acceptors/donors, are attractive candidates for the conversion of solar energy into chemical energy. Several different classes of sensitizers have been studied and among these, ruthenium(II) polypyridyl complexes continue to attract major attention. LÄS MER

7. 20. Biological and Biophysical Studies on Ruthenium Complexes

   Författare :Anna Mårtensson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; metal susceptibility; DNA; antimicrobial; circular dichroism; ruthenium complex; linear dichroism; isothermal titration calorimetry; intercalation;

   Sammanfattning : Small molecules that interact with DNA through intercalation are attractive candidates for treatments against cancer and microbial infections. Octahedral ruthenium(II) polypyridyl complexes, being substitution-inert, readily synthesized and coordinately saturated, has the potential of being developed in to a new family of drugs. LÄS MER
