  2. 16. Aspects on wettability and surface composition of modified wood

    Author : Lars-Elof Bryne; Ove Söderström; Charles R. Frihart; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wettability; contact angle; work of adhesion; Lewis acid-base; modified wood; Building engineering; Byggnadsteknik;

    Abstract : Wood is often combined with other materials such as thermoplastics, adhesives and coatings. In general, combinations of wood and polymers especially in outdoor exposure have poor long-term durability. READ MORE

  4. 17. Thermodynamics of Peptide Nucleic Acid Interactions with DNA

    Author : Tommi Ratilainen; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thermodynamics; enthalpy-entropy compensation; ionic strength; nucleic acids; fluorescence energy transfer; PNA; calorimetry; sequence-specific binding;

    Abstract : Peptide Nucleic Acid (PNA) is a DNA mimic with the natural nucleobases attached to a charge-neutral pseudopeptide backbone. It has remarkably strong and sequence-specific binding affinity to natural nucleic acids (DNA and RNA), mainly attributed to the lack of charge in the PNA backbone. READ MORE

  5. 18. Chlorite: Geochemical properties, Dissolution kinetcis and Ni(II) sorption

    Author : Åsa Zazzi; Zoltan Szabo; Susanna Wold; Peter Vilks; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chlorite; dissolution kinetics; Ni II sorption; surface complexation; Chemistry; Kemi;

    Abstract : In Sweden, among other countries, a deep multi-barrier geological repository, KBS-3, is planned for the burial of nuclear waste. One of the barriers is identified as the grantic bedrock itself and in this environment chlorite is present at surfaces in fracture zones. READ MORE

  6. 19. Some Aspects of Physicochemical Properties of DNA and RNA

    Author : Sandipta Acharya; Jyoti Chattopadhyaya; Piet Herdewijn; Uppsala universitet; []
    Keywords : Bioorganic chemistry; nucleic acids; hydrogen-bonding; stacking; single-stranded; NMR; molecular dynamics; Bioorganisk kemi;

    Abstract : This thesis is based on nine research publications (I – IX) on structure and reactivity of RNA vis-à-vis DNA. The DNA and RNA are made of flexible pentose sugar units, polyelectrolytic phosphodiester backbone, and heterocyclic nucleobases. DNA stores our genetic code, whereas RNA is involved both in protein biosynthesis and catalysis. READ MORE

  7. 20. Functional and structural properties of eukaryotic DNA polymerase epsilon

    Author : Olga Chilkova; Erik Johansson; Per Elias; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; eukaryotic DNA replication; DNA polymerase epsilon; protein-DNA interaction; Biochemistry; Biokemi;

    Abstract : In eukaryotes there are three DNA polymerases which are essential for the replication of chromosomal DNA: DNA polymerase alpha (Pol alpha), DNA polymerase delta (Pol delta) and DNA polymerase epsilon (Pol epsilon). In vitro studies of viral DNA replication showed that Pol alpha and Pol delta are sufficient for DNA replication on both leading and lagging DNA strands, thus leaving the function of Pol epsilon unknown.
