11. High Valent Metal Oxo Complexes as Oxidation Catalysts
Abstract : A series of new dioxomolybdenum(VI) and -tungsten(VI) complexes of tripodal tetradentate and tridentate amino bis- and monophenolate ligands have been synthesized and characterized. The majority of the complexes are mononuclear, but dimeric and trimeric oxo-bridged M(VI) (M = Mo, W) were also obtained. READ MORE

13. Selective oxidation over mixed oxide catalysts
Abstract : Since the metal oxide catalysts used in many chemical processes show very high selectivity for the products aimed at, both today and in the future, they play a key role in the environmentally and economically sustainable production of chemical intermediates. Two processes of this sort have been studied in the thesis: the ammoxidation of propane and propene over a Mo-V-Nb-Te-oxide catalyst and the selective oxidation of methanol over vanadium-based catalysts.

14. Structural Properties of Palladium-Manganese Alloys
Abstract : Structural properties of adsorbed overlayers on well-defined single crystals and of Palladium-Manganese surface alloys formed on Pd(100) have been investigated using synchrotron-based photoemission, scanning tunneling microscopy and Fourier-transform infrared spectroscopy. The experimental valence electronic structure of PdMn systems on Pd(100) is compared to density functional calculations (DFT). READ MORE

15. Laboratory and stellar spectroscopy of the complex ions Fe+, Mo+, Th+ and U+
Abstract : The new generation of high resolution astronomical instruments such as the Hubble Space Telescope (HST) or the Very Large Telescope (VLT) has renewed the demand for accurate atomic parameters like wavelengths, oscillator strengths and line profiles accompanied by reliable uncertainty estimates. Fourier transform spectroscopy has proven to be a powerful tool when measuring these parameters. READ MORE
