21. Unveiling Catalytic Species in Suspension/Solution-Based Reactions by In Situ X-Ray Absorption Spectroscopy : Evolution of Palladium and Ruthenium Species
Sammanfattning : The palladium (Pd) and ruthenium (Ru) species in several attractive catalysts have been probed using X-ray absorption spectroscopy (XAS). The study of catalyst evolution in suspension- and solution-based reactions was the primary aim. It was achieved by performing in situ XAS experiments on Pd and Ru over the course of the reactions.

22. Mononuclear Ruthenium Complexes that Catalyze Water to Dioxgen Oxidation
Sammanfattning : The theme of this thesis is the development of mononuclear Ru-based complexes that are capable of catalyzing the water oxidation (or O2-evolving) reaction, e.g. 2 H2O → O2 + 4 H+ + 4 e−. Several families of mononuclear Ru water oxidation catalysts were designed and prepared. LÄS MER
23. RuO4 interaction with surfaces in the containment of nuclear power plant
Sammanfattning : During a severe accident different fission products will be released from the nuclear fuel and some of them may eventually reach the containment building. Ruthenium is considered to be an important fission product due to the possible formation of volatile oxides. LÄS MER
24. Theoretical Photochemistry : Halogenated Arenes, Phytochromobilin, Ru(II)polypyridyl complexes and 6-4 photoadducts
Sammanfattning : This thesis presents Quantum Chemical calculations on the Photochemistry of Halogenated benzenes, Phytochromobilin, Ruthenium Polypyridyl complexes and 6-4 photoadducts in DNA. The work is focused on improving the understanding of a number of experimentally observed photochemical processes in these systems. LÄS MER
25. Investigation of the behaviour of gaseous I2 and RuO4 in different atmospheres
Sammanfattning : During a severe accident several hazardous and radiotoxic fission products can be released and constitute a threat to the environment. Two of the most important fission products are iodine and ruthenium which will be accumulated after inhalation in the human body in the thyroid gland and in the respiratory organs, respectively.
