    Sammanfattning : Polymer blends are utilized for a variety of applications, not least in pharmaceutical coatings for controlled release of drugs. For instance, blends of ethyl cellulose (EC) and the water-soluble hydroxypropyl cellulose (HPC) can be used to coat drug pellets for oral extendedrelease formulations. LÄS MER

  5. 4. Towards bacterial valorization of low molecular weight lignin

    Detta är en avhandling från Department of Chemical Engineering, Lund University

    Författare :Krithika Ravi; Lund University.; Lunds universitet.; [2019-10-24]
    Nyckelord :Pseudomonas putida; Microbacterium sp.; Guaiacol; Syringate; Kraft lignin; Bioconversion; Biorefineries;

    Sammanfattning : Lignin is one of the major constituents in lignocellulosic biomass and is the mostabundant source of renewable aromatics on terrestrial ecosystems. The workcarried out in this thesis concerns bacterial conversion of low molecular weightlignin. LÄS MER

  7. 5. Protein Interaction Studies with Low Molecular Weight Ligands Applications for Drug Discovery, Basic Research and Diagnostic Tool Design

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Tony Christopeit; Uppsala universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis, the interactions between different proteins and small ligands were characterized by surface plasmon resonance spectroscopy (SPR) and fluorescence resonance energy transfer (FRET) based assays.   For the C-reactive protein (CRP), a new type of artificial binder was identified which allows designing diagnostic assays superior to commonly used standard assays.
