Manipulating the Structural and ElectronicProperties of Epitaxial NaNbO$_{3}$ Films via Strainand Stoichiometry
Schriften des Forschungszentrums Jülich Reihe Schlüsseltechnologien / Key Technologies 136, VI, 114 pp (2016)
Due to their intriguing dielectric, pyroelectric, elasto-electric, or opto-electric properties,oxide ferroelectrics are vital candidates for the fabrication of most electronics. However, theseextraordinary properties exist mainly in the temperature regime around the ferroelectricphase transition, which is usually several hundreds of K away from room temperature.Therefore, the manipulation of oxide ferroelectrics, especially moving the ferroelectrictransition towards room temperature, is of great interest for application and also basicresearch.In this thesis, we demonstrate this using examples of NaNbO3 films.

Process-based modelling of regional waterand energy fluxes taking into account measuredneutron intensities by cosmic-ray probes
Schriften des Forschungszentrums Jülich Reihe Energie & Umwelt / Energy & Environment 362, xvi, 135 pp (2017)
At the land surface, the hydrologic cycle is strongly linked to soil water content (SWC). Landsurface models describe the mass and energy fluxes at the land surface and to the atmospherewith a spatial resolution of a few km2 at the catchment scale. [...]

Light Trapping by Light Treatment - Direct Laser Interference Patterning for theTexturing of Front Contacts in Thin-Film Silicon Solar Cells
Schriften des Forschungszentrums Jülich Reihe Energie & Umwelt / Energy & Environment 359, vi, 172, XI pp (2017)
To further increase the energy conversion eciency of thin-lm silicon solar cells,the minimization of reection losses by eective light trapping is essential. Lighttrapping is achieved by introducing textured surfaces in the layer stack of a solarcell. [...]

Realistic Bandwidth Estimation in the Theoretically Predicted Radionuclide Inventory of PWR-UO2 Spent Fuel Derived from Reactor Design and Operating Data
Schriften des Forschungszentrums Jülich Reihe Energie & Umwelt / Energy & Environment 358, XI, 129 pp (2017)
Nuclear energy for power generation produces heat-generating high- and intermediate levelradioactive waste (HLWand ILW) for which a safe solution for the handling and disposal has tobe found. Currently, many European countries consider the final disposal of HLW and ILW indeep geological formations as the most preferable option. [...]

Transport, co-transport, and retention of functionalized multi-walled carbon nanotubes in porous media
Schriften des Forschungszentrums Jülich Reihe Energie & Umwelt / Energy & Environment 352, VII, 112 (2016)
The information on transport and retention behavior of functionalized multiwalledcarbon nanotubes (MWCNTs) in porous media is essential for environmentalprotection and remediation due to the wide applications of MWCNTs and lack ofdisposal regulations. The aim of this study is therefore to investigate: i) the attachment,transport, retention and remobilization of 14C-labeled functionalized MWCNTs indifferent porous media (quartz sand (QS), goethite-coated quartz sand (GQS), andsoil), ii) co-transport of pollutants (chlordecone (CLD) and sulfadiazine (SDZ)) byMWCNTs, and iii) the role of surfactant on MWCNTs transport as a modeled soilremediation process, based on column and batch experiments at the environmentallyrelevant concentrations under various physiochemical conditions.

A Laboratory Workflow to Study Transformation and Ecotoxicity of Emerging Pharmaceuticals and Personal Care Products in Water- Integrating Electrochemistry-mass spectrometry and Bioassays
186 p. (2017)
In the last two decades, the exponential increase of pharmaceuticals and personal care products (PPCPs) in the aquatic environment has received growing concern due to their potential risks to the environment and human health. PPCPs can undergo a series of physical, chemical and/or microbial transformation processes in natural water and engineered systems, to form a wide range of transformation products (TPs). [...]
