    Sammanfattning : Complex transition metals oxyhalides containing a lone pair element, such as tellurium (IV), form an attractive research field because there is a high probability of finding new low-dimensionally arranged compounds and, particularly, a low-dimensionally arranged transition metals substructures, leading to interesting physical properties. Tellurium (IV) can drive the formation of many unusual structures because of its stereochemically active lone pair electrons, E. LÄS MER

  5. 9. In-situ activated hydrogen evolution from pH-neutral electrolytes

    Författare :John Gustavsson; Ann Cornell; Olof Forsén; KTH; []
    Nyckelord :molybdate; trivalent cations; electrolysis; hypochlorite reduction; films; electrolysis; chlorate process; molybdat; trivalenta katjoner; elektrolys; hypokloritreduktion; filmer; kloratprocessen; SRA - Energy; SRA - Energi;

    Sammanfattning : The goal of this work was to better understand how molybdate and trivalent cations can be used as additives to pH neutral electrolytes to activate the Hydrogen Evolution Reaction (HER). Special emphasis was laid on the chlorate process and therefore also to some of the other effects that the additives may have in that particular process. LÄS MER

  7. 10. Platelet adhesion and P-selectin surface expression

    Författare :Per A. Whiss; Nils Olav Solum; Linköpings universitet; []
    Nyckelord :divalent cations; ELISA; nicotine; nitric oxide; platelet adhesion; P-selectin; MEDICINE; MEDICIN;

    Sammanfattning : Upon injury in a blood vessel, platelets become activated and adbere to prevent blood loss. Activated platelets express adhesion molecules on their surface that also make leukocytes adhere to the injury. One such molecule, which also is expressed on endothelium, is the glycoprotein P-selectin. LÄS MER
