Thickness dependence of structure and piezoelectric properties at nanoscale of polycrystalline PZT thin films
(2012-10-31)
Lead zirconate titanate Pb(Zr 0.50Ti 0.50)O 3 (PZT) thin films were deposited by a polymeric chemical method on Pt(111)/Ti/SiO2/Si substrates to understand the mechanisms of phase transformations and the effect of film ...
New materials for energy and biomedical applications
(2014-01-15)
We have conducted research works on the synthesis and characterization of ceramic materials for energy technologies and the characterization of bioceramics and composites for dental applications. La0.50Li 0.50TiO3 nanoparticles ...
Synthesis and crystal phase evaluation of hydroxylapatite using the rietveld-maximum entropy method
(2004-12-01)
Bioceramic systems based on hydroxylapatite (HAP) are an important class of bioactive materials that may promote bone regeneration. The aim of this research was to evaluate how the stoichiometry of HAP influences its ...
Rietveld refinements of SnO2 ceramic powders doped with ZnO, WO3, CoO, Nb2O5 and MoO3
(2007-01-01)
Polycrystalline materials of SnO2 doped with ZnO, WO 3, CoO, Nb2O5, and MoO3. were synthesized by solid state reaction. X-ray powder diffraction data were collected with Cu Kα radiation from a Rigaku-Rint 2000 rotating ...
Size-dependent phase transitions in nanostructured zirconia-scandia solid solutions.
(Laboratório Nacional de Luz Síncrotron.Campinas, 2013-02-26)
Size effects on phase stability and phase transitions in technologically relevant materials have received growing attention. Several works reported that metastable phases can be retained at room temperature in nanomaterials, ...
