Study Data from D.G. Stroppa et al Provide New Insights into Nanocrystals

June 24, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Research findings on Nanocrystals are discussed in a new report. According to news originating from Braga, Portugal, by NewsRx correspondents, research stated, "This work reports the analysis of the distribution of Gd atoms and the quantification of O vacancies applied to individual CeO2 and Gd-doped CeO2 nanocrystals by electron energy-loss spectroscopy."

Our news journalists obtained a quote from the research, "The concentration of O vacancies measured on the undoped system (6.3 +/- 2.6%) matches the expected value given the typical Ce3+ content previously reported for CeO2 nanoparticles. The doped nanoparticles have an uneven distribution of dopant atoms and an atypical amount of O vacant sites (37.7 +/- 4.1%)."

According to the news editors, the research concluded: "The measured decrease of the O content induced by Gd doping cannot be explained solely by the charge balance including Ce3+ and Gd3+ ions."
