Topological transport in non-Abelian spin textures from first principles
Jülich : Forschungszentrum Jülich GmbH Zetralbibliothek, Verlag, Schriften des Forschungszentrums Jülich Reihe Schlüsseltechnologien / Key Technologies 197, vii, 158 () = Dissertation, RWTH Aachen University, 2019
Recently, skyrmions attracted huge attention due to their topological character which ensuressurprisingly stable, particle-like magnetic excitations on small scales with distinctive dynamicalproperties. Their characteristic transport signature—the topological Hall effect—has becomean established tool for detection of topologically non-trivial ferromagnetic textures. [...]

Bedeutung flüchtiger organischer Verbindungen aus landwirtschaftlich genutzten Pflanzen für die Chemie der Atmosphäre
[Juel-3465]
Jülich : Forschungszentrum Jülich GmbH Zentralbibliothek, Verlag, Berichte des Forschungszentrums Jülich 3465, 213 p. () = Dissertation, RWTH Aachen, 1997
In this work a new method for the qualitative and quantitative analysis of volatile organic compounds (C$_{5}$ - C$_{15}$) has been developed. The limit of detection is as low as 20 pg/l for many substances (corresponding to mixing ratios in the lower pptv-range) and that the response is linear up to concentrations of 0.1 $\mu$g/l (corresponding to mixing ratios of some 10 ppbv). [...]

Synthesis and Analysis of Spinel Cathode Materials for High Voltage Solid-State Lithium Batteries
Jülich : Forschungszentrum Jülich GmbH Zentralbibliothek, Verlag, Schriften des Forschungszentrums Jülich Reihe Energie & Umwelt / Energy & Environment 458, iv, 141 () = Dissertation, RWTH Aachen University, 2018
One of the most challenging issues in our modern society is the problem of energystorage. Energy storage systems are needed for the storage of energy produced bywind or solar energies especially, which are essential to reduce the environmentalimpact from the utilization of fossil fuels, such as air pollution and global warming.Furthermore, the flourishing development of portable systems including smartphones, computers and powered tools demand small and compact energy storagesystems to prolong their working hours and to minimize the overall device volume.Similarly, the demand for electric vehicles, for the reduction of petroleum consumption,requires efficient and compact storage systems with high energy densities.Among the energy storage systems, lithium-ion batteries offer the highest energydensity and the highest coulombic efficiency.

Coupling a Solid Oxide Fuel Cell with a Biomass Gasifier: Degradation Mechanisms and Alternative Anode Materials
Jülich : Forschungszentrum Jülich GmbH Zentralbibliothek, Verlag, Schriften des Forschungszentrums Jülich Reihe Energie & Umwelt / Energy & Environment 460, II, 112 () = Dissertation, RWTH Aachen University, 2019
Anode-supported solid oxide fuel cells (SOFCs) with a state-of-the-art Ni/YSZ anode have been tested insimulated bio-syngas with controlled addition of tars and sulfur as model molecules to study the influenceof impurities on the degradation of SOFCs. The phenol tar causes macro- and micro-scale structuralchanges in the support including erosion, Ni coarsening, and carbon fiber formation. [...]
