Automated precolumn derivatization procedures in HPLC for biomedical and clinical applications
This thesis describes three automated precolumn derivatization procedures for the analysis of carboxylic group-containing compounds. After derivatization with a suitable label, the derivatives are separated on reversed-phashed HPLC and detected by fluorescence. ... Zie: Summar

The Solution Precursor Plasma Spraying Process for Making Zirconia Based Electrolytes
Ceramic layers, such as yttria-stabilized zirconia or scandia-stabilized zirconia, used for functional layers of solid oxide fuel cells, i.e. the gas tight oxygen ion conductive electrolyte or as ceramic component in the porous cermet anode, were obtained by the Solution Precursor Plasma Spray (SPPS) process. The influence of different solvent types on microstructure was analyzed by comparison of coatings sprayed with water-based solution to ethanol-based one. Use of solvent with low surface tension and low boiling point enhances splat formation, coating micro-structure and crystalline structure. Parameter adjustment to receive coatings from nitrate solutions with ethanol as solvent was carried out. Results of Raman spectroscopy indicate that an intermediate of both nitrates (zirconyl and scandium nitrate hydrate) was deposited
Modulation of internuclear communication in multinuclear Ruthenium(II) polypyridyl complexes
The syntheses and characterisation of a series of mononuclear and dinuclear ruthenium polypyridyl complexes based on the bridging ligands 1,3-bis-[5-(2-pyridyl)-1H-1,2,4-triazol-3-yl]benzene, 1,4-bis-[5-(2-pyridyl)-1H-1,2,4-triazol-3-yl]benzene, 2,5-bis-[5-(2-pyridyl)-1H-1,2,4-triazol-3-yl]thiophene, 2,5-bis-[5-pyrazinyl-1H-1,2,4-triazol-3-yl]thiophene are reported. Electrochemical studies indicate that in these systems, the ground state interaction is critically dependent on the nature of the bridging ligand and its protonation state, with strong and weak interactions being observed for thiophene- and phenylene-bridged complexes, respectively
International Taxation and Takeover Premiums in Cross-border M&As
Cross-border M&As can trigger a higher international taxation of the targetâs income. Non-resident dividend withholding taxes may be imposed by the target country, while additional corporate income taxation can be imposed by the acquiring country. Our evidence suggests that takeover premiums fully reflect non-resident dividend withholding taxes, while there is some evidence that they reflect corporate income taxation by the acquiring country as well. In contrast, acquiring firm stock market returns around the bid announcement do not appear to reflect either type of taxation. These results are consistent with previous findings that the gains of M&As primarily accrue to target shareholders
Cross-border Mobility for Electric Vehicles: Selected results from one of the first cross-border field tests in Europe
This book provides selected results from the accompanying research of the project CROME. The vision of the project was to create and test a safe, seamless, user-friendly and reliable mobility with electric vehicles between France and Germany as a prefiguration of a pan-European electric mobility system. Major aims were contributions to the European standardisation process of charging infrastructure for electric mobility and corresponding services, and to provide an early customer feedback
