Optimierung eines photochemischen molekularen Apparats durch Feinjustierung des Brückenliganden
(Universität Ulm, 2016-11-29)
Der Brückenligand eines gut erforschten photochemischen molekularen Apparats (PMD) zur Wasserstoffproduktion wurde modifiziert und zwei isomere, dinukleare Ru-Pt-PMDs erhalten. Der Einfluss der Substitution auf die ...
Adsorption behavior and structure formation of ionic liquids on single crystalline surfaces
(Universität Ulm, 2017-02-10)
In the present thesis the interaction of the ionic liquids [BMP][TFSA], [OMIM][TFSA] and [EMIM][TFSA] on the single crystalline surfaces Au(111), Ag(111), Cu(111) and TiO2(110) was investigated with STM and XPS under UHV ...
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 ...
Functionalized oligothiophenes for application in organic solar cells
(Universität Ulm, 2016-04-28)
The steady increase in power conversion efficiencies (PCE) of donor/acceptor bulk hetero-junction (BHJ) organic solar cells (OSC) over the recent years was made possible by systematic improvement of the donor materials ...
Fused S,N-heteroacenes and thiophene-substituted Ruthenium(II) complexes for organic solar cells
(Universität Ulm, 2016-07-05)
The objective of this thesis was the preparation of functionalized thiophene-comprising oligomers and Ru(II) sensitizers for application in organic solar cells. As electron-rich unit S,N-heteroacenes were implemented in ...
Protein corona composition of functionalised and loaded silica nanoparticles formed in foetal calf serum
(Universität Ulm, 2017-11-27)
Nanoparticles on silicon basis are biocompatible, biodegradable and also easily modifiable, which makes them a prime candidate for clinical research and medical applications. Especially a detailed understanding of the ...
Studies of high voltage LiNi0.5Mn1.5O4 as positive electrode material in lithium ion cells
(Universität Ulm, 2017-02-02)
Since their first commercialization in 1991, Li-ion batteries (LIBs) present many advantages with respect to other commercial battery technologies. In particular, their higher specific energy and specific power make LIBs ...
Development of selective sorbent materials for the determination of polychlorinated biphenyls (PCBs) in the environment
(Universität Ulm, 2016-11-21)
In this thesis, synthesis of molecularly imprinted polymers with molecular recognition for polychlorinated biphenyls (PCBs) as well as the application of the polymers as pre-concentration and clean-up sorbents in the ...
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 ...
Kinetics and mechanisms of the hydrogenation of CO2 to methanol on oxide-supported Au catalysts
(Universität Ulm, 2017-12-14)
Due to the depletion of fossil fuel reserves, new ways of energy production from renewable sources such as the wind and the sun have to be explored and realized in the near future. The widespread use of renewable energies ...
