Cluster Coordination and Photoluminescence Properties of alpha-Ag2WO4 Microcrystals
(Amer Chemical Soc, 2012-10-15)
In this paper, we report our initial research to obtain hexagonal rod-like elongated silver tungstate (alpha-Ag2WO4) microcrystals by different methods [sonochemistry (SC), coprecipitation (CP), and conventional hydrothermal ...
EXAFS and XRD analyses of the structural evolutions involved during drying of SnO2 hydrogels
(1995-11-01)
In order to determine structural changes during drying of inorganic gels, the local and long-range order structure of SnO2-x(OH)2x xerogels resulting from drying hydrogels with different concentrations of electrolyte (Cl- ...

Estudo de pós cerâmicos de PbTiO3 utilizando-se o método dos precursores poliméricos.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2000-11-30)
THE STUDY OF PbTiO3 (PT) CERAMIC POWDERS USING THE POLYMERIC PRECURSOR METHOD was started by the preparation of a precursor solution of metallic cations. Citric acid was used as quelation agent and ethylene glycol as ...
On the local order of amorphous La2Mo2O6.7
(Royal Society of Chemistry, 2017-05)
The amorphous reduction product of the oxide ion conductor La2Mo2O9 was previously shown to be a good, sulphur-tolerant, anode material for solid oxide fuel cell devices (X. C. Lu, J. H. Zhu, J. Electrochem. Soc., 2008, ...
