1. Flavins as Biomimetic Catalysts for Sulfoxidation by H2O2 : Catalyst Immobilization in Ionic Liquid for H2O2 Oxidations
Sammanfattning : 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. LÄS MER
2. Direct H2O2 synthesis over dilute PdAu alloys
Sammanfattning : 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. LÄS MER
3. Stability of Alternative Nuclear Fuel Materials in Aqueous Systems
Sammanfattning : 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. LÄS MER
4. Radiation Induced Oxidative Dissolution of UO2
Sammanfattning : 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. LÄS MER
5. Effects of HCO3- and ionic strength on the oxidation and dissolution of UO2
Sammanfattning : 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.
