An improved method for preparation of SrTiO3 nanoparticles
Da Silva, Luis F.; Maia, Lauro; Bernardi, Maria Inês B.; Andres, Juan; Mastelaro, Valmor Roberto Elsevier (2011)SrTiO3 nanoparticles were synthesized for the first time via a modified polymeric precursor method. The samples were characterized by thermogravimetry, X-ray diffraction (XRD), BET surface area, micro-Raman spectroscopy, ... -
Effect of polyvinyl alcohol on the shape, photoluminescence and photocatalytic properties of PbMoO4 microcrystals
Araújo, Vinícius Dantas; Tranquilin, R. L.; Motta, F. V.; Paskocimas, C. A.; Bernardi, Maria Inês B.; Cavalcante, Laécio Santos; Andres, Juan; Longo, Elson; Bomio, M. R. D. Elsevier (2014)For this study, lead molybdate (PbMoO4) microcrystals were prepared by the co-precipitation method and processed using a conventional hydrothermal method at 100 °C for 10 min with polyvinyl alcohol (PVA) as the capping ... -
Insight into the Effects of Fe Addition on the Local Structure and Electronic Properties of SrTiO3
Da Silva, Luis F.; M’Peko, Jean Claude; Andres, Juan; Beltran, Armando; Gracia, Lourdes; Bernardi, Maria Inês B.; Mesquita, Alexandre; Antonelli, Eduardo; Moreira, Mario Lucio; Mastelaro, Valmor Roberto American Chemical Society (2014-01)This paper reports an experimental and theoretical investigation of the effects of adding Fe to the perovskite strontium titanate SrTiO3. The effects include changes in the short-order range structure as well as in the ... -
Structural and optical properties of CaTiO3 perovskite-based materials obtained by microwave-assisted hydrothermal synthesis: An experimental and theoretical insight
Moreira, Mario Lucio; Paris, Elaine Cristina; Do Nascimento, G. S.; Longo, V. M.; Sambrano, Julio; Mastelaro, Valmor Roberto; Bernardi, Maria Inês B.; Andres, Juan; Varela, José A.; Longo, Elson Elsevier (2009)CaTiO3 powders were synthesized using both a polymeric precursor method (CTref) and a microwave-assisted hydrothermal (CTHTMW) method in order to compare the chemical and physical properties of the perovskite-based material ...
