  1. 1. Synthesis and modification of potential CO2 adsorbents : Amine modified silica and calcium carbonates

    Författare :Baroz Aziz; Niklas Hedin; Lennart Bergström; Helmut Cölfen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amine-modified silica; carbon capture; Fractional factorial design; IR spectroscopy; calcium carbonate; Materials Chemistry; materialkemi;

    Sammanfattning : The prospect of rapid changes to the climate due to global warming is subject of public concern. The need to reduce the emissions of atmospheric green house gases and in particular carbon dioxide is greater than ever. Extensive research is performed to find new solutions and new materials, which tackles this problem in economically benign way. LÄS MER

  3. 2. Mesoporous supported lipid bilayers

    Författare :Maria Claesson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; FRAP; Lipid bilayer; Mesoporous; AFM; Vesicle; Titania; Silica; QCM-D;

    Sammanfattning : AbstractLipid bilayers are commonly used as simplified model systems of living cell membranes. They have shown to be important components in the development of biosensing devices where the bilayer acts as a host for transmembrane proteins, such as ion channels, that are utilized as sensing elements.

  4. 3. Formation of Mesoporous Materials and their use as Lipid Bilayer Supports

    Författare :Maria Wallin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; tethered lipid bilayers; meso-ordered PEG-DA hydrogels; dendrimers; porous silica and titania; lipid bilayers; biosensing;

    Sammanfattning : Mesoporous materials have acquired great scientific interest in various applications; something that is largely due to that their properties, such as pore size, pore orientation, material composition and surface chemistry, can be controlled to a large extent. One idea, which has been investigated in this thesis, is to use mesoporous materials as supports for lipid bilayers and by doing so fabricate devices that mimic the cell wall and at the same time has sufficient mechanical robustness for practical use.

  5. 4. Toxicity and biocompatibility of nanoparticles, and studies on oxidative stress and DNA damage

    Författare :Ylva Rodhe; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Oxidative stress is associated with several diseases, either as a cause or a consequence. Chronic kidney disease (CKD) is one example of a disease in which elevated levels of oxidative stress are frequently reported. LÄS MER
