1. Structural and Antibacterial Properties of Silver(I) Compounds with N-donor Ligands: A Challenge for Medical Applications
Abstract : In this thesis, new silver(I) nitrate compounds with N-donor heterocyclic ligands are described. The structures of the obtained crystalline compounds 1-19 were analysed using X-ray single-crystal diffraction. READ MORE

2. Copper(II) Azido Complexes: Synthesis, X-ray structures, thermal and magnetic properties
Abstract : This thesis focuses on the synthesis and X-ray structure analysis of seven copper(II) and one cobalt(II) azido coordination polymer with quinoline and pyrazine derivatives as bridging co-ligands. The synthesis of these complexes were done by direct mixing of the metal salt (Cu(NO3)2 and CoCl2) and the organic ligand (pyrazinecarbonitrile, quinoxaline, quinoline-4-carboxylic acid and 2,5-dimethylpyrazine) solutions followed by the dropwise addition of aqueous sodium azide (NaN3) with continuous stirring.

3. Optical Modeling and Characterization of Layers and Multilayer Structures : Organic Optoelectronic Devices and Spectroscopic Ellipsometry
Abstract : This dissertation is on the subject of modeling and characterization of layers and multilayer structures with respect to their optical properties and characteristics. A number of different systems have been investigated; among them multilayer structures in the form of organic optoelectronic devices, anisotropic layers of conjugated polymers as well as inhomogeneous layers of porous silicon and oxidized silver.

4. Biological Laboratory X-Ray Microscopy
Abstract : Soft x-ray microscopy in the water window (? ≈ 2.3 − 4.3 nm) is a powerful technique for high-resolution biological imaging. The strong natural contrast between carbon-based structures and water allows visualization of hydrated and unstained samples, while providing enough transmission through up to ∼ 10 μm of organic matter.

5. Time-resolved x-ray diffraction of nanostructured samples
Abstract : The work presented in this thesis is based on time-resolved x-ray diffraction studies of InSb (111) samples. The experiments were carried out using a pump-probe configuration using short laser pulses as the pump and x-rays as the probe. Laser excitation leads to the formation of a strain pulse that propagates through the sample. READ MORE
