Operando Tracking of Solution-Phase Concentration Profiles in Li-Ion Battery Positive Electrodes Using X-ray Fluorescence
Unraveling the Origin of Moisture Stability of Halide Solid-State Electrolytes by In Situ and Operando Synchrotron X-ray Analytical Techniques
An efficient CO2 reduction electrocatalyst, comprising Ni and N in situ co-doped into porous and Ni nanoparticle-embedded carbon nanotubes (NiNxCNT), is developed from a sustainable and representative bioligand – folic acid.
Size, Composition and Alignment of VO2 microrod crystals by the reduction of V2O5 thin films, and their optical properties through insulator-metal transitions
Using bulk-sensitive X-ray microdiffraction in Laue geometry, the distribution of twin domains in La2−xSrxCuO4 under uniaxial pressure is imaged. It is observed that the twin domain with a shorter lattice parameter along the direction of pressure is unstable under compression and disappears completely only under moderate pressure.
Tungstate accumulates in bone and can be resistant to chelation therapies typically used to remove heavy metals in vivo. Here, tungstate is shown to accumulate in mouse bone tissue in a persistent, insoluble form proposed to be condensed polytungstate.
A conductive phase is observed during the carbon coating process of lithium iron phosphate and the phase content is size, temperature, and annealing atmosphere dependent. The formation of this phase is related to the reducing capability of the carbon coating process.
Micro X-ray fluorescence imaging (μ-XFI) and micro X-ray absorption near-edge spectroscopy (μ-XANES) techniques are utilized to investigate the distribution and speciation of zinc in the gills of rainbow trout (Oncorhynchus mykiss) during acute waterborne zinc exposure to understand the interactions with cadmium or copper.

VESPERS is a hard X-ray microprobe beamline capable of providing a high level of complementary structural and analytical information. The techniques of X-ray diffraction and X-ray fluorescence spectroscopy are employed to analyze a microscopic volume in the sample, as well as X-ray absorption spectroscopy. Multi-bandpass and pink beam capability are built in to meet various requirements. A mm-sized beam is also available for the experiments.
