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 ...
Design und 2D Kristallisation von organischen Liganden und Metallkomplexen für die Entwicklung neuer funktioneller Oberflächen
In this work molecules with catalytic and magnetic properties were used to structure and to functionalize surfaces. For this we used the simple but powerful technique of molecular self organisation which is employed since ...
Untersuchungen von polymeren Netzwerken mit Methoden der Rasterkraftmikroskopie
A suitable technique for scrutinizing polymer networks is given by atomic force microscopy AFM. This sophisticated method enables not only imaging of structures but also nanomanipulation and detection of material properties ...
The reproductive biology of euglossine-pollinated plants in the natural reserve Nouragues, French Guiana
The reproductive biology of several euglossine-pollinated species of an understory community in the natural reserve Nouragues in French Guiana were studied. The first two chapters deal with the pollination biology of three ...
Reaktionen im begrenzten Raum zur Herstellung und Verkapselung von Pigmenten
The PhD thesis shows that various reactions can be conducted in a miniemulsion: They can take place in the nanodroplets of a miniemulsion, but - in case of reaction partners that are characterized by a different hydrophilicity ...
1,2-Thiaphospholo[2,3-a]phosphirane und 1,2,3-Diazaphospholo[3,4-a]phosphirane, eine neuartige Klasse von Phosphanliganden
Die Befähigung von 1,2-Thiaphospholo[2,3-a]phosphiranen und 1,2,3-Diazaphospholo[3,4-a]phosphiranen zur Komplexbildung mit einem Wolframpentacarbonyl-Fragment und die Folgeraktionen dieser Komplexe bei thermischer Belastung ...
Synthese von Polydien- und Polydien-Copolymernanopartikeln mittels Miniemulsionsverfahrens
The adaptation of the miniemulsion technique to the requirements of radical polymerization of volatile or gaseous diene monomers, like isoprene or butadiene, and the copolymerization of the same was the major objective of ...
