Development of all solid state fluoride ion batteries based on thin film electrolytes
(Universität Ulm, 2017-03-14)
For current solid state fluoride ion battery, a critical problem is that the practical capacity is considerably below that of the theoretical value and fades rapidly during the further cycles. One reason for this problem ...
Synthesis and properties of fully conjugated cyclo[n]thiophenes and investigation into a boron-templated aryl-coupling method
(Universität Ulm, 2016-05-30)
Series of fully alpha-conjugated cyclooligothiophenes C[n3]Ts with n = 3, 4, 5, 6, 7, 8, and 9 have been synthesised via a platinum templated cyclisation method and caracterised. Comparison with other C[n]Ts with different ...
Operando investigations of particle size and support effects during the selective CO methanation over oxide supported Ru nanoparticles in idealized and realistic H2 feed gases
In addition to the increasing importance in technical applications of the selective CO methanation, it is also an ideal model reaction for testing the catalytic performance of supported Ru catalysts in hydrogenation ...
Untersuchungen zur Erhöhung der Strombelastbarkeit manganbasierter Kathodenmaterialien für Lithium-Ionen Batterien
(Universität Ulm, 2016-08-23)
Lithium-ion battery technology is one of the key enabler for electromobility. High cyclic stability, high capacity and rate capability as well as low costs are demanded. In this thesis two approaches are being attempt ...
Development of enhanced analytical methods for ultratrace determination of mercury in natural water
(Universität Ulm, 2017-08-15)
Mercury (Hg) is a ubiquitous pollutant that is emitted to the atmosphere from both anthropogenic and natural sources. Human exposure to Hg occurs mainly from consumption of contaminated fish, as Hg exhibits very high ...
Molecular aspects of RNA-recognition by the neuronal mRNA transport factor Staufen 2
(Universität Ulm, 2018-07-19)
Staufen (Stau) is a double-stranded RNA-binding protein (dsRBP) originally identified as an mRNA transport factor and germ-cell marker in Drosophila. The mammalian homolog Staufen 2 (Stau2) is specifically expressed in ...
Chemical and structural analysis of Xylella fastidiosa biofilm formation
(Universität Ulm, 2018-03-20)
Xylella fastidiosa (Xf) is a gram-negative phytopathogen bacterium that affects the xylem vessels of citrus, olives, grapevines, coffee, almonds among many other plants by vascular occlusion [1–3]. Diseases such as citrus ...
Towards rational design of N-heterocyclic carbene bridged photochemical molecular devices for water reduction
(Universität Ulm, 2017-11-09)
In order to achieve fair and easy access to energy for all and at the same time tackle climate change, the switch from fossil fuels to renewables is inevitable. Among renewable energy sources the energy delivered by the ...
Das CRISPR-Cas-System von Haloferax volcanii: CRISPRi und Autoimmunität
(Universität Ulm, 2017-09-13)
The CRISPR-Cas system is a prokaryotic adaptive, heritable immune system. The crRNA, which orchestrates the sequence-specific binding of a target sequence, constitutes a key component of the defence response. Employing ...
Funktionelle mesostrukturierte Beschichtungen auf Basis von SiO2 und TiO2
Die Synthese der dünnen mesostrukturierten Beschichtungen erfolgte über den Sol-Gel Prozess, durch Tauch- bzw. Schleuderbeschichten auf Si- bzw. Glas- Substrate. Die Funktionalisierung mesostrukturierter Beschichtungen auf ...
