  2. 1. Flavins as Biomimetic Catalysts for Sulfoxidation by H2O2 : Catalyst Immobilization in Ionic Liquid for H2O2 Oxidations

    Author : Auri Lindén; Jan-Erling Bäckvall; Peter Somfai; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biomimetic; oxidation; catalysis; ionic liquid; hydrogen peroxide; Organic chemistry; Organisk kemi;

    Abstract : This thesis deals with the development of catalytic oxidation reactions utilizing hydrogen peroxide as terminal oxidant. The main focus has been to find flavin catalysts that are easy to handle and stable to store but still able to perform the desired reaction. READ MORE

  4. 2. Direct H2O2 synthesis over dilute PdAu alloys

    Author : Rasmus Svensson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; kinetic Monte Carlo; H2O2 synthesis; metal-water interface; dynamics; kinetic modeling; dilute alloys; catalysis; density functional theory;

    Abstract : Heterogeneous catalysis is crucial in a range of technological and industrial processes. Depending on the composition of the catalyst and the reaction conditions, it is possible to steer the activity and the selectivity towards the desired products. READ MORE

    Abstract : Nuclear power produces a large portion of the electricity worldwide. It has been the largest low-carbon energy source for more than 30 years and has played an essential role in the security of energy supplies for many countries. READ MORE

  6. 4. Radiation Induced Oxidative Dissolution of UO2

    Author : Ella Ekeroth; Mats Jonsson; Bernd Grambow; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; radiation; radiolysis; UO2; spent nuclear fuel; radicals; oxidants; reductants; rate constants; dissolution; H2O2; H2; Nuclear chemistry; Kärnkemi;

    Abstract : Sammanfattning Denna doktorsavhandling berör oxidativ upplösning av UO2 (som modellsubstans för utbränt kärnbränsle) orsakad av radiolys av vatten samt effekten av H2 på denna denna process. Hastighetskonstanter för oxidation av UO2-pulver med olika oxidanter såsom H2O2 har bestämts experimentellt. READ MORE

  7. 5. Effects of HCO3- and ionic strength on the oxidation and dissolution of UO2

    Author : Mohammad Moshin Hossain; Mats Jonsson; Olle Wahlberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; UO2; H2O2; spent nuclear fuel; HCO3-; ionic strength; oxidation; dissolution; surface site density.; Chemistry; Kemi;

    Abstract : The kinetics for radiation induced dissolution of spent nuclear fuel is a key issue in the safety assessment of a future deep repository. Spent nuclear fuel mainly consists of UO2 and therefore the release of radionuclides (fission products and actinides) is assumed to be governed by the oxidation and subsequent dissolution of the UO2 matrix.
