Localized Excitation Fluorescence Imaging (LEFI)
… excitation of fluorescent cells, acquisition of fluorescence through the scaffold, and fluorescence mapping based on the position of the excitation light. To evaluate the capability and accuracy of the imaging system, human endothelial cells, stably expressing green fluorescent protein (GFP), …

Nanofocusing Refractive X-Ray Lenses
… The first one employs a high-resolution scanning fluorescence mapping of a geological sample, and the second one is a coherent x-ray diffraction imaging (CXDI) experiment. CXDI is able to reconstruct the illuminated object from recorded coherent diffraction patterns. In a scanning mode, referred …

In-operando techniques for early-stage corrosion
… approaches were developed: confocal fluorescence microscopy, synchrotron X-ray absorption and diffraction, and electron microscopy. These techniques address various aspects of the corrosion process – mineralogy, oxidation state, domain structure, etc, and provide crucial information …

Heterogeneous Redox Chemistries in Layered Oxide Materials for Lithium-Ion Batteries
… in LiCoO2. Combining synchrotron-based X-ray fluorescence mapping, micro-diffraction, and spectroscopic techniques, we reveal that geometrically necessary dislocations can facilitate the charging reactions in LiCoO2 grains. Our study illustrates that the heterogeneous redox chemistries can be …

Metal impurities in n-type crystalline silicon for photovoltaics : simulation, synchrotron-based characterization, and mitigation
… In particular, synchrotron-based micro-X-ray fluorescence mapping is used to non-destructively evaluate metal impurity evolution during processing. This thesis demonstrates that metal impurity redistribution during solar cell processing is similar in n- and p-type mc-Si but the relative …

X-ray microscope performance enhancement through control architecture change
The goal of this thesis is to apply control algorithms to improve the performance of nanopositioning devices used on the beamline in Advanced Photon Source (APS) at Argonne National Laboratory (ANL). A prototype device, better known as the Early User Instrument (EUI) was the subject of this work. …
