Quantenmechanische Berechnung von NMR chemischen Verschiebungen und indirekten Spin-Spin Kopplungskonstanten von Carbokationen
(Universität Ulm, 2017-01-10)
Diese Arbeit berichtet über die quantenmechanische Berechnung von [C4H7] + sowie α-, β- und γ-silyl substituierten Carbokationen. Neben Strukturoptimierungen mit Elektronenkorrelationsmethoden (CCSD und RI-MP2) ist die ...
Elektrolytalterung in Lithium-Ionen-Batterien
(Universität Ulm, 2016-12-06)
This work focuses on the investigations of electrolyte aging, aiming at monitoring and assessing of electrolyte side reactions in lithium ion cells by means of electrochemical tests and gas chromatography analysis. Therefore ...
Measurement of reduced dipole matrix elements in 40Ca+ and construction of a scalable light-ion interface
(Universität Ulm, 2017-01-10)
In the first part of this thesis, a method for determining transition dipole matrix elements is introduced. It combines measuring absorptive and dispersive atom-light interactions off-resonant to the transition in question ...
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 ...
Proline-Quaterthiophene hybrids: Synthesis and self-assembly
(Universität Ulm, 2017-02-01)
The aim of this thesis was to synthesize new asymmetric pi-conjugated A-B systems, which are able to self-assemble in chiral suprastructures due to the presence of a single amino acid and to investigate them with respect ...
Electrochemical properties of several forms of carbon
(Universität Ulm, 2017-02-10)
Increasing demand for clean, globally available energy, provokes the development of alternative or nonconventional energy storage sources with higher energy density and power delivery. Therefore, supercapacitors have ...
Several proteins form variable RNA editing complexes in plant organelles
(Universität Ulm, 2017-03-02)
In RNA editing in plant organelles, PPR (Pentatricopeptide Repeat) proteins with an E or E and DYW domains at the C-terminus are important participants for recognizing the specific cis-elements. These proteins are able to ...
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 ...
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 ...
Architecture and mechanical properties of crosslinked Keratin 8/18 networks
(Universität Ulm, 2016-07-19)
The cytoskeleton, which consists of microtubules, actin filaments and intermediate filaments, stabilizes cells under mechanical stress. Especially important for stress resistance is the intermediate filament network. Since ...
