    Sammanfattning : New strategies are needed to counter the growing problem of bacterial resistance to antibiotics. One such strategy is to design compounds that target bacterial virulence, which could work separately or in concert with conventional bacteriostatic or bactericidal antibiotics. LÄS MER

  3. 3. Structural Studies of Hyaluronan Hydrogels

    Detta är en avhandling från ; Department of Molecular Sciences, Swedish University of Agricultural Sciences

    Författare :Frida Wende; Sveriges lantbruksuniversitet.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Hydrogels consist of cross-linked polymer networks with the ability to absorb large amounts of water. In this thesis, the structures of hydrogels consisting of hyaluronic acid (HA) cross-linked by 1,4-butanediol diglycidyl ether (BDDE) have been investigated. LÄS MER

  4. 4. Tellurium interaction with surfaces in the containment and sea-salt residue

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola
