  1. 11. Development of Polyamide Solvent Extraction Reagents for Trivalent Lanthanides

    Författare :Mikhail S Tyumentsev; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Polyamides; Solvent Extraction; Europium; Rare Earth Elements; Lanthanides; Malonamides;

    Sammanfattning : Rare earth elements (REEs), including lanthanides, are critical materials for many industrial technologies. As a result recycling of end-of-life products containing REEs might be beneficial, as this could partially satisfy the growing demands of industry for these elements. LÄS MER

  2. 12. Iron-nitrogen containing carbon catalysts for oxygen reduction in fuel cells

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Caroline Janson; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; active site; mesoporous carbon; fuel cell; electron paramagnetic resonance; oxygen reduction reaction; cathode catalyst; non-precious metal catalyst;

    Sammanfattning : New solutions to efficiently convert energy are needed to mitigate global climate changes and sustain the needs of the growing population. An energy device with high potential is the proton exchange membrane (PEM) fuel cell. PEM fuel cells can convert chemical energy to electrical energy with extraordinary high conversion efficiency.

  3. 13. Carbohydrate and metabonomic studies by NMR spectroscopy

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Gustav Nestor; Sveriges lantbruksuniversitet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : NMR spectroscopy can be used to investigate organic and biomolecular structures, both as pure compounds and in complex mixtures. In this thesis NMR spectroscopy was used for carbohydrate and metabonomic studies. Lipopolysaccharides are major components of the outer cell membrane of Gram-negative bacteria and are involved in pathogenic interactions. LÄS MER

  4. 14. Theoretical aspects of tetrapyrrole biochemistry

    Detta är en avhandling från Theoretical Chemistry, Lund University

    Författare :Kasper Jensen; Lunds universitet.; Lund University.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proteiner; enzymologi; Theoretical chemistry; quantum chemistry; Teoretisk kemi; kvantkemi; enzymology; Proteins; protein; enzyme; density functional; Heme; B12;

    Sammanfattning : Popular Abstract in Swedish Moderna teoretiska simuleringar kan ge signifikant insikt i biokemiska problem i en omfattning som ständigt ökar. Med hjälp av datorkraft och sofistikerade program från forskare inom området have vi studerat en serie av problem som är relaterat till de så kallade tetrapyrrolkofaktorerna som finns hos alla levande organismer.

  5. 15. Structural and Functional Studies of Gas6

    Detta är en avhandling från Department of Clinical Chemistry, Lund University

    Författare :Jonas Stenhoff; Lunds universitet.; Lund University.; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk kemi; Clinical chemistry; EDTA; calcium; multimer; monomer; platelets; Mer; Axl; vitamin K; Gas6; human circulation; soluble receptor; Tyro3; receptor tyrosine kinases; growth factor;

    Sammanfattning : The vitamin K-dependent and ubiquitously expressed 82 kDa glycoprotein product of the growth-arrest-specific-gene 6, Gas6, shows 44% sequence identity to the anticoagulant protein, protein S. Both proteins share further the same domain organization. LÄS MER
