  1. 16. Supported Palladium Nanoparticles for Sustainable Cross-Coupling and Oxidation Reactions

    Författare :Vlad Pascanu; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The work presented in this thesis aims to combine the rich chemistry ofpalladium and the benefits of heterogeneous catalysis with metal-organic frameworks(MOFs) in developing robust materials that are recyclable and adaptable to operationunder a continuous flow regime.Two new catalysts were created based on palladium nanoparticles in themesoporous MOFs MIL-101 and MIL-88B.

    Sammanfattning : The HIV protease is an essential enzyme for HIV replication and constitutes an important target in the treatment of HIV/AIDS. Efficient combination therapies using inhibitors of the reverse transcriptase and protease enzymes have led many to reevaluate HIV infections from a terminal condition to a chronic-but-manageable disease in the developed world.

    Sammanfattning : Soft matter, here, liquids and polymers, have adaptability to a surrounding geometry. They intrinsically have advantageous characteristics from a mechanical perspective, such as flowing and wetting on surrounding surfaces, giving compliant, conformal and deformable behavior. LÄS MER
