  1. 1. Crystal structures of human deoxyribonucleotidases

    Författare :Agnes Rinaldo-Matthis; Pär Nordlund; David K Stammers; Stockholms universitet; []
    Nyckelord :crystal structure;

    Sammanfattning : Human 5’-deoxyribonucleotidases are ubiquitous enzymes that catalyze the dephosphorylation of deoxyribonucleoside monophosphates to their nucleoside form. They participate in the regulation of deoxyribonucleotide pools and protect DNA replication from inbalance of precursors. LÄS MER

  3. 2. Chirality in Crystal Engineering

    Författare :Krister Larsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; networks; 2; coordination chemistry; crystal engineering; 10; 3-nets; hydrogen bonding; 2 -biimidazole; single crystal X-ray diffraction; bis-chelating ligands; chirality;

    Sammanfattning : Crystal engineering combines supramolecular chemistry with solid state chemistry. The goal is to make molecular entities assemble into predefined structures with specific properties. At the same time much research is focused on the understanding of the intermolecular interactions governing the crystallisation process. LÄS MER

  4. 3. Structures and Properties of Ferroelectric Liquid Crystal Displays

    Författare :Marek Matuszczyk; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; smectic; displays; dielectric anisotropy and biaxiality; surface-stabilized structure; dielectric; paraelectric; liquid crystal alignment; electroclinic effect; grey scale; polarization; multiplexing; liquid crystal LC ; orthogonal and tilted phases; chirality; aligning layer; ferroelectric; polyimide; rubbing; light valves and modulators; SSFLC;

    Sammanfattning : Liquid crystals have unique physical properties as they combine the features of solids and liquids. In thermotropic liquid crystals the degree of order varies with temperature resulting in an appearance of intermediate phases. LÄS MER

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; xyloglucan; xyloglucan endo-transglycosylase hydrolase; xyloglucan endo-hydrolase; xyloglucan endo-transglycosylase; XET; xyloglucan oligosaccharides; synthesis; carbohydrate; cellulose; crystal structure; fiber; surface modification; Populus tremula x Populus tremuloides; Hybrid aspen; nasturtium; NXG; Biochemistry; Biokemi;

    Sammanfattning : Cellulosabaserade material är världens rikligast förekommande förnyelsebara råvara. Växters cellväggar är naturliga kompositmaterial där den kristallina cellulosan är inbäddad i en väv av hemicellulosa, strukturproteiner och lignin. LÄS MER

  7. 5. Crystal structures of 1,4-ethanonaphthalenes : studies of Diels-Alder adducts of 2,4-cyclohexadienones

    Författare :Bengt Karlsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The present summary concerns crystal structure investigations of the 1,4-ethanonaphtha1ene class of compounds. The structures of eight such compounds have been determined by the present author and coworkers. LÄS MER
