Bent Crystal Laue Analyzer (BCLA) for Copper Speciation Studies and Recent Progress on Optics Testing at 1-BM

Speaker: Naresh Kujala, Advanced Photon Source
XSD Presentation
401/A1100 @ 11:00 AM
View Description
In this talk, I will present the design of Bent Crystal Laue Analyzer (BCLA) detection system for copper speciation in biological samples. The analyzer has energy resolution of 14 eV@ Cu Kα line and it has notable advantages to resolve the Cu Kα1, Kα2, and Kβ fluorescence lines while offering a very low background. The designed BCLA will be used on copper speciation studies in biological samples with specific applications to cancer biology. I will also present newly reconfigured optics and detector test beamline (1-BM) at the Advanced Photon Source-Argonne National Laboratory. I will show the beamline experimental stations layout and beamline optical components. The beamline have two modes of operations: White beam mode and monochromatic beam mode. Here I will give an overview of the recent progress on optics testing including the testing of Kirkpatrick-Baez (K-B) mirrors and measurement of focus spot; X-ray microscopy experimental setup for investigating the performance of Multilayer Laue lens (MLL) and Fresnel Zone Plates; Silicon Bent Crystal Analyzer testing experimental setup; and Talbot x-ray grating Interferometry for measurement of coherence lengths. I will also discuss x-ray Topography for crystal studies. Finally, I will present the optical ray-tracing studies for test set-ups that take advantage of the polarization variation of the bending magnet radiation above and below the horizontal plane of the 1-BM beamline.

Examining Relationships Between Synthesis, Structure and Magnetism in Nanomaterials with X-ray Spectroscopy

Speaker: Dr. George E. Sterbinsky, Brookhaven National Laboratory
XSD Presentation
401/A1100 @ 11:00 AM
View Description
This talk details synchrotron x-ray investigations of two ferromagnetic materials that show unexpected magnetic properties on the nanoscale: cobalt carbide nanoparticles and epitaxial lanthanum cobaltite thin films. Cobalt carbide is not known to be a strong ferromagnet in the bulk phase, yet nanoparticles of this material synthesized by wet chemical methods have properties comparable to known rare-earth free permanent magnets. Lanthanum cobaltite is a paramagnetic material that becomes ferromagnetic when synthesized as a thin film. To gain insight into the unique magnetic properties of these materials, a variety of x-ray spectroscopy based experiments were carried out. In lanthanum cobaltite, the effects of epitaxial strain on the atomic and electronic structures of the material were measured using x-ray absorption fine structure (XAFS) spectroscopy and x-ray diffraction. From the observed atomic and electronic structures, the nature of the strain induced magnetic phase is deduced. A combination of x-ray magnetic circular dichroism (XMCD) spectroscopy and time resolved quick XAFS spectroscopy was used examine the relationship between the Co-carbide nanoparticle synthesis and the resultant magnetic properties. These results give insight into how to tailor the synthesis of nanomaterials to optimize magnetic properties.
