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."

The news correspondents report that additional information may be obtained from D.G. Stroppa, Int Iberian Nanotechnol Lab INL, Braga, Portugal. Additional authors for this research include C.J. Dalmaschio, L. Houben, J. Barthel, L.A. Montoro, E.R. Leite and A.J. Ramirez.
