  1. 1. Hydrogen Bonding in Liquid Alcohols

    Författare :Per Sillrén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrogen Bonded Liquids; Physics of liquids; Diffraction; Monte Carlo Simulation; Alcohols; Neutron Scattering; EPSR;

    Sammanfattning : Hydrogen bonded (H-bonded) materials, such as water, alcohols, sugars, and even DNA, are extremely important for biology, as well as chemical industry. Alcohols are used as solvents in paints, in perfumes, as cleaners, anti-freezers, or as an alternative to petrol in combustion engines. LÄS MER

  4. 3. Application of the 2-Pyridone Hydrogen-Bonding Motif in Supramolecular Catalysis and in Phenanthroline Based Ligands

    Författare :Stefan Jonsson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; X-ray crystallography; Phenanthroline; Supramolecular Catalysis; Jacobsen-Katsuki Epoxidation; Mn salen ; Hydrogen-bonding; Supramolecular Chemistry; 2-Pyridone; Organisk kemi;

    Sammanfattning : This thesis concentrates on the development, synthesis and evaluation of supramolecular systems, assembled from its components by means of hydrogen bonding, using the self-complementary 2-pyridone motif. The thesis is divided in two parts. LÄS MER

  5. 4. Studies on the Non-covalent Interactions (Stereoelectronics, Stacking and Hydrogen Bonding) in the Self-assembly of DNA and RNA

    Författare :Parag Acharya; Jyoti Chattopadhyaya; Frank Seela; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioorganic chemistry; nucleic acids; NMR; Stereoelectronic effects; Hydrogen Bonding; Stacking; Bioorganisk kemi; Bioorganic chemistry; Bioorganisk kemi;

    Sammanfattning : This thesis is based on ten publications (Papers I-X). The phosphodiester backbone makes DNA or RNA to behave as polyelectrolyte, the pentose sugar gives the flexibility, and the aglycones promote the self-assembly or the ligand-binding process. LÄS MER

  7. 5. Structure Dependent Chemical and Biological Interactions of Poly(urethane urea)s

    Författare :Katrin Gisselfält; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomaterial; synthesis; hydrogen bonding; biological interactions; structure; properties; poly urethane urea ;

    Sammanfattning : Poly(urethane urea)s, PUURs, are widely used in both industrial and biological applications because of excellent physical and mechanical properties and good biocompatibility in a variety of applications. Both the processing and the tailoring of specific properties of PUUR demand great knowledge of structure-property relationships. LÄS MER
