Reports Outline Nanoparticles Findings from University of Michigan

February 21, 2014



By a News Reporter-Staff News Editor at Science Letter -- Current study results on Nanoparticles have been published. According to news reporting out of Ann Arbor, Michigan, by NewsRx editors, research stated, "In this work, scanning-transmission electron microscope tomography and atom-probe tomography were successfully applied to characterize the Y- and Cr-rich secondary phases present in an oxide dispersion strengthened reduced activation Fe-12Cr alloy in three dimensions."

Our news journalists obtained a quote from the research from the University of Michigan, "Electron energy loss spectroscopy, energy dispersive spectroscopy and energy filtered transmission electron microscopy were used to obtain analytical information about the region used for electron tomography reconstruction. The results obtained with these techniques provided accurate information regarding the Y-rich nanoparticle dispersion and chemistry and their association with the Cr-rich precipitates present in the alloy."

According to the news editors, the research concluded: "Reconstructions show that Y-rich nanoparticles are frequently found to be embedded within the larger Cr-rich carbides and oxides, which would decrease the amount of nanoparticles capable of strengthening the matrix."
