  1. 1. Biotic Ligand model : A tool for risk assessment of metals in Scandinavian fresh waters?

    Författare :Sabina Hoppe; Magnus Breitholtz; Jon-Petter Gustafsson; Karel De Schamphelaere; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; BLM; Soft freshwaters; Sweden; Cu; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Products from iron and copper mining are among Sweden’s top exports. However, as the metals are excavated, they often end up in the aquatic environment where they can cause toxicity. LÄS MER

  4. 3. Ligand Dependent Regioselectivity in Palladium Mediated Allylic Alkylation

    Författare :Charlotte Johansson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Palladium; allylic alkylation; η3-allyl palladium complexes; regioselectivity; PN-ligand; memory effects; dynamics; ligand effect; trans effects.;

    Sammanfattning : In this thesis, different aspects on ligand dependent regioselectivity in palladium mediated allylic alkylation have been studied. It is believed that the regioselectivity is a result of nucleophilic attack trans to phosphorous when applying ligands wih different donor atoms. LÄS MER

  5. 4. Tissue Factor and CD40 Ligand : Markers for the Interplay of Coagulation and Inflammation in the Acute Coronary Syndrome

    Författare :Anders Mälarstig; Agneta Siegbahn; Lars Wallentin; Taavo Tenno; Fiona Green; Uppsala universitet; []
    Nyckelord :Molecular medicine; tissue factor; CD40 ligand; gene expression; single nucleotide polymorphism; acute coronary syndrome; myocardial infarction; coagulation; inflammation; Molekylärmedicin;

    Sammanfattning : BACKGROUND: Tissue factor (TF) is a 47 kDa transmembrane glycoprotein known as the main initiator of blood coagulation. CD40 ligand is another membrane molecule, which ligates to cell types associated with atherosclerotic plaques thereby mediating intraplaque inflammation and weakening of the fibrous cap. LÄS MER

  7. 5. Asymmetric Catalysis : Ligand Design and Conformational Studies

    Författare :Kristina Hallman; KTH; []
    Nyckelord :asymmetric catalysis; chiral ligand; oxazolines; conformational study; allylic substitution; polymer-bound ligands; dendritic ligands; crown ether; oxidations; palladacycle;

    Sammanfattning : This thesis deals with the design of ligands for efficientasymmetric catalysis and studies of the conformation of theligands in the catalytically active complexes. All ligandsdeveloped contain chiral oxazoline heterocycles. LÄS MER
