In-situ Environmental Transmission Electron Microscopy Investigation of Perovskite Oxide Thin Films During Electrochemical Oxygen Evolution Reaction.
(2022-07-21)Despite many theoretical and experimental efforts to find active catalysts in oxygen evolution reaction (OER), the mechanism for high activity and long-term OER stability remains elusive. Catalyst-electrolyte interface ... -
Low-dose, high-throughput scanning small-angle X-ray scattering of adherent mouse embryonic fibroblasts
(2022-02-24)Biological cells are highly variable: differences in e. g. gene expression emerge even among monoclonal cells in the same culture dish. The characterization of a highly variable statistical population calls for high-throughput ... -
Fast, Three-Dimensional Fluorescence Imaging of Living Cells
(2022-01-21)This thesis focuses on multi-plane fluorescence microscopy for fast live-cell imaging. To improve the performance of multi-plane microscopy, I developed new image analysis methods. I used these methods to measure and analyze ... -
Novel type of neutron polarization analysis using the multianalyser at PUMA implementation, characterization and first experiments
(2019-11-07)The PUMA polarization analysis introduces a new method for polarization analysis with neutrons, for the first time allowing the simultaneous measurement of both spin states by detecting spin-up and spin-down neutrons in ... -
In Situ X-ray Spectroscopy and Environmental TEM Study on Manganite Water Oxidation Catalysts
(2017-11-29)This thesis presents in situ studies on the active states of manganite water oxidation catalysts in water vapor. The study in chapter 2 probes the surface electronics of the strongly correlated Pr1-xCaxMnO3 (0Advanced x-ray multilayer waveguide optics
(2017-09-12)The aim of this thesis is to demonstrate that x-ray waveguide optics can be gen- eralized from a single guiding film to an array of planar waveguides, enabling more complex and controllable phenomena of field propagation ...Scanning X-Ray Nanodiffraction on Dictyostelium discoideum
(2015-11-06)In the recent years, novel focussing optics for synchrotron radiation sources became available, which now allow focussing the x-radiation down to 100\,nm (FWHM). Thus, the typically poor spatial resolution of Small Angle ...
