Artigo IPEN-doc 21301 Oxygen stoichiometry of Basub(0.50)Srsub(0.50)Cosub(0.80)Fesub(0.20)Osub(3-'delta') obtained by EDTA-citrate method and measured by X-ray and neutron diffraction2015 - BONTURIM, EVERTON; MAZZOCCHI, VERA L.; PARENTE, CARLOS B.R.; MESTNIK FILHO, JOSE; LIMA, NELSON B. de; SEO, EMILIA S.M.The compound Ba0.50Sr0.50Co0.80Fe0.20O3–d (BSCF) has been used as a good candidate for air electrodes in Intermediate Temperature Solid Oxide Fuel Cells. Present work deals with the oxygen vacancy of this compound synthesized by using the EDTA–Citrate method. To obtain a single-phase sample, three portions of the compound were calcined at 700, 800 and 900 C. Only the sample calcined at 900 C showed a single phase. The stoichiometry of the single-phase sample, in particular of the oxygen atom, was determined by applying the combined X-ray and neutron Rietveld refinement to X-ray and neutron powder diffraction patterns measured with the sample.Resumo IPEN-doc 20386 Crystalline structure and oxigen stoichiometry of the Ba0.50Sr0.50Co0.80Fe0.20O3-d powders obtained by EDTA-Citrate method measured by X-ray and neutron diffraction2014 - BONTURIM, EVERTON; LIMA, NELSON B. de; MAZZOCCHI, VERA L.; PARENTE, CARLOS B.R.; MESTNIK FILHO, JOSE; SEO, EMILIA S.M.Resumo IPEN-doc 17643 Rietveld analysis of Besub(3)Alsub(2)(SiOsub(3))sub(6) employing high-resolution neutron powder diffraction patterns2011 - PARENTE, C.B.R.; MAZZOCCHI, V.L.; MESTNIK FILHO, J.; MASCARENHAS, Y.P.; WATANABE, S.Resumo IPEN-doc 16601 Rietveld refinement of Nd and Pr doped BaYsub(2)Fsub(8) single crystals employing neutron powder diffraction patterns2008 - MAZZOCCHI, V.L.; MESTNIK FILHO, J.; PARENTE, C.B.R.; CRUZ, S.F.A.; BALDOCHI, S.L.Resumo IPEN-doc 16047 X-ray and neutron diffraction analysis of Ca-Sr-Ti-Fe-O compounds2010 - CARMO, J.R.; MARTINEZ, L.G.; MAZZOCCHI, V.L.; PARENTE, C.B.R.; MESTNIK FILHO, J.; ORLANDO, M.T.A.; CORREA, H.P.S.Resumo IPEN-doc 17801 Nanostructured CaSrTiFeO polycrystalline materials: synthesis, structural and microstructural characterization2011 - MARTINEZ, L.G.; MAZZOCCHI, V.L.; PARENTE, C.B.R.; MESTNIK FILHO, J.; CARMO, J.R.; MUCCILLO, R.Resumo IPEN-doc 12471 Characterization of the new IPEN-CNENSP PSD neutron diffractometer2007 - PARENTE, C.B.R.; MAZZOCCHI, V.L.; MESTNIK FILHO, J.; MASCARENHAS, Y.P.Artigo IPEN-doc 17186 Hydrostatic pressure cells development for x-ray and neutrons experiments2011 - PASSAMAI JUNIOR, JOSE L.; PINHEIRO, CHRISTIANO J.G.; ORLANDO, MARCOS T.D.; CORREA, HAMILTON P.S.; ROSSI, JESUALDO L.; MAZZOCCHI, VERA L.; PARENTE, CARLOS B.R.; FILHO, JOSE M.; MELO, FRANCISCO C.L. de; MARTINEZ, LUIS G.; PASSOS, CARLOS A.C.Artigo IPEN-doc 17064 Historical review of neutron spectrometry and diffraction in brazil - 50 years2011 - VOI, DANTE L.; STASIULEVICIUS, ROBERTO; RODRIGUES, CLAUDIO; FERREIRA, FRANCISCO J.O.; PARENTE, CARLOS B.R.; MAZZOCCHI, VERA L.; MESTNIK FILHO, JOSE; PUGLIESI, REYNALDOArtigo IPEN-doc 17703 Neutron diffraction patterns measured with a high-resolution powder diffractometers installed on a low-flux reactor2011 - MAZZOCCHI, V.L.; PARENTE, C.B.R.; MESTNIK FILHO, J.; MASCARENHAS, Y.P.
