  1. 11. Synthesis and Characterisation of Carbide Derived Carbons

    Detta är en avhandling från Stockholm : Institutionen för fysikalisk kemi, oorganisk kemi och strukturkemi

    Författare :Sigita Urbonaite; Gunnar Svensson; Mats Johnsson; Rik Brydson; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Carbide derived carbons; Gas adsorption; EELS; Raman; Porous carbons; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; strukturkemi; Structural Chemistry;

    Sammanfattning : Carbide derived carbons (CDCs) have been synthesised through chlorination of VC, TiC, WC, TaC, NbC, HfC and ZrC at different temperatures. The aim of the investigation was to systematically study changes of structural and adsorption properties depending on the synthesis conditions. LÄS MER

  2. 12. Refined crystal structures of Zn(II)- and Cu(II)-alcohol dehydrogenase : a comparative study

    Detta är en avhandling från Stockholm : Stockholm University

    Författare :Salam al-Karadaghi; [1993]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; strukturkemi; Structural Chemistry;

    Sammanfattning : The crystal structure of the ternary complex of horse liver alcohol dehydrogenase (LADH) with the coenzyme NADH and inhibitor dimethyl sulphoxide (DMSO) (space group PI) has been refined by simulated annealing with molecular dynamics and restrained positional refinement using the program system XPLOR. The resulting crystallographic R- factor is 17. LÄS MER

  3. 13. Crystallographic Aspects of Protein Phasing at Very Low Resolution

    Detta är en avhandling från Stockholm : Stockholm University

    Författare :Klas Andersson; Jens Nyborg; [1999]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; strukturkemi; Structural Chemistry;

    Sammanfattning : A protein crystallographic method for obtaining structure factor phases of low-order reflections is presented. It is based on four observations: 1) The electron density inside proteins is relatively smooth and uniform at low resolution. LÄS MER
