  3. 22. Studies on Lean NOx Reduction with Ammonia. Catalysts and Sensors

    Författare :Mikaela Wallin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; catalysis; Pt SiO2; NOx reduction; gas sensor; DFT; SCR; H-ZSM-5; in situ FTIR; LCAO; DRIFT; high throughput screening; transient ammonia supply; ammonia; microemulsion; perovskite;

    Sammanfattning : Selective catalytic reduction of NOx with ammonia, NH3-SCR, is a promising technique to reduce NOx under lean conditions, e.g. in diesel engine exhausts. The main objective of this thesis was to gain further understanding of key parameters affecting the performance of catalysts and sensors for NH3-SCR. LÄS MER

  5. 24. Lipid based formulations for topical application: characterization and delivery of active substances

    Författare :Johanna Bender; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bicontinuous cubic phase; phytantriol; passive diffusion; bicontinuous sponge phase; stratum corneum; W O microemulsion; monoolein; medium chain triglycerides;

    Sammanfattning : In this thesis, the interaction between lipids, solvents and active substances in lipid based formulations have been studied and related to formulation structure or release behavior on human skin or a model thereof. For the different investigations, isotropic equilibrium lipid phases, i.e. LÄS MER

  7. 25. Leukemia chemotherapy : experimental studies on pharmacological optimisation

    Författare :Michèle Masquelier; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Our main goal has been to identify new means to improve chemotherapy of acute leukaemia: 1. By using low-density lipoprotein (LDL) as a drug carrier to increase the selectivity of antileukemic drugs, based on high LDL uptake in acute myeloid leukemia (AML) cells. LÄS MER
