Locally resolving mass spectrometry to study the product gas evolution above planar microstructured model catalysts
Dissertation
A scanning mass spectrometer (SMS) setup was developed allowing for locally resolved probing of the gas phase composition atop planar model catalysts. A thin quartz capillary which connects the reaction room to the analysis ...
Development of TiO2 rutile as negative electrode material for lithium ion batteries
Dissertation
Lithium ion batteries are capable to meet the increasing demand of energy storage systems especially in the field of hybrid electric vehicles (HEVs), electric vehicles (EVs) and renewable energies. However a lot of research ...
mEst1A (mouse Ever Shorter Telomeres 1A) regulates telomere length and RNA quality control in murine stem cells
Dissertation
Est1A/SMG6 controls telomere elongation by mediating telomerase recruitment. In addition, it is an essential component of the endonucleolytic branch of the Nonsense-mediated mRNA decay (NMD) pathway, which controls RNA ...
Engineering Corynebacterium glutamicum as a designer-bug for the bio-based production of chemical building blocks and biofuel
Dissertation
The restriction of fossil raw materials, as well as the impact of their use on the environment heads to a global social and economic crisis. Therefore, a strong political and technical interest arises for the replacement ...
Transition metal complexes and ligand design for organic optoelectronics
Dissertation
A variety of chelating N^N ligands has been synthesized using the CuAAC (click) reaction, either to functionalize the periphery of the ligand or to use the resulting triazole moiety as a part of the chelate. In most cases, ...
Characterization of bifidobacterial adhesion to intestinal epithelial cells
Dissertation
Adhesion of probiotics is discussed as a prerequisite for the persistence and the colonization of the gut. Based on previous studies of our group, the strain B. bifidum S17 could be identified as promising candidate to ...
Transmissionselektronenmikroskopische Analysen zur Defektreduktion mittels SiNx Zwischenschichten in AlGaN Heterostrukturen
Dissertation
AlGaN with high Al concentration has attracted great attention because of its potential application to optoelectronic devices in the UV range due to its large direct band gap of up to 6eV. In order to avoid UV light ...
Ein Simulationsmodell für den Protonentransfer auf Metalloberflächen
Dissertation
The objective of this thesis was to develop a new model for the electrochemical proton transfer to metal electrodes to be used within the framework of classical molecular dynamics simulations. Employing this model, a ...
Hydroxyalkylnitrate (Nitrooxyalkanole) als Spurenstoffe in belasteter und unbelasteter Atmosphäre
Dissertation
Hydroxyl alkyl nitrates are the central topic in this work. Vicinal hydroxy alkyl nitrates are suspected to form from unsaturated hydrocarbons, mainly emitted by motor traffic.
In order to investigate the presence of ...
Untersuchungen von an der Lösungsmittelbildung beteiligten Transkriptionsfaktoren in Clostridium acetobutylicum
Dissertation
Clostridium acetobutylicum ist ein anaerobes, stäbchenförmiges Bakterium, welches in der Lage ist Sporen zu bilden. Es zeichnet sich vor allem durch seinen biphasischen Gärungsstoffwechsel aus. So werden in der ersten Phase ...
