In-situ measurements of the Liquid-Phase Sintering of Zinc Oxide
… measured in situ, using 1 mm thick samples and synchrotron X-rays. Thermodynamic calculations were performed to explain phase formation, composition, stability of additive oxides and influence of the oxygen fugacity on sintering. Sb2O4, pyrochlore, trirutile and spinel were formed at …

Fabrication of critical-angle transmission gratings for high efficiency x-ray spectroscopy
… waves, such as extreme ultraviolet (EUV) and x rays, are of interest in various science fields including astrophysics, fine pitch gratings with high diffraction efficiency are required. The critical angle transmission (CAT) grating has been devised to enhance diffraction efficiency of a …

In-situ synchrotron studies of turbine blade thermal barrier coatings under extreme environments
… measurements are taken using the high-energy Synchrotron X-Rays and analyzed to provide high-resolution depth-resolved strain. This study will include fatigue comparisons through use of samples, which are both 'as-coated' as well as aged to various stages in a TBC lifespan. Studies reveal that …

Grazing Incidence X-ray Scattering from Magnetic Thin Films and Nanostructures
Grazing incidence scattering of synchrotron x-rays has been used to characterize the structure of magnetic thin films and periodic nanostructures. The combined metal and metal oxide films have been chosen to clarify the effects of growth processing techniques in technologically important magnetic …

Error estimation in whole bone microstrain measurement when using digital volume correlation
… resolution of 4-5 um. The use of monochromatic x-rays (such synchrotron x rays) can increase resolution and reduce the signal-to-noise ratio in the CT scanning process, thus reducing the SE calculated by DVC.

Tiny Space Magnets: X-ray Microscopy and Nanopaleomagnetism of Meteoritic Metal
… of FeNi microstructures was imaged using synchrotron X-rays. Magnetic contrast is generated using X-ray magnetic circular dichroism. The dimensions of tetrataenite islands within the cloudy zone directly correlate with cooling rates. Cooling rates vary from ~0.5–10,000°C/Myr and correspond …

The dynamics of ultrafast motion in biological and bio-inspired systems: the case study of click beetles
… of the ultrafast motion are derived from synchrotron x-ray and natural light high-speed videos. High-speed synchrotron x-ray imaging allows for the visualization and analysis of the hinge's internal structures movements during the release. The dynamics of the energy release are …
