Influence of the precursor salts in the synthesis of CaSnO3 by the polymeric precursor method
(Springer, 2007-03-01)
CaSnO3 was synthesized by the polymeric precursor method, using different precursor salts as (CH3COO)(2)Ca. H2O, Ca(NO3)(2). 4H(2)O, CaCl2. 2H(2)O and CaCO3, leading to different results. Powder precursor was characterized ...

Release of Nitrosamines and Nitrosamine Precursors from Scrap Tires | Environmental Science & Technology Letters
(American Chemical Society, 2021)
Materials used during manufacturing of tires can be a source of nitrosamines and/or their precursors. Here, we examined the leaching of nitrosamines and nitrosamine precursors from scrap tires under different test conditions. ...
Profiles of cognitive precursors to reading acquisition. Contributions to a developmental perspective of adult literacy
(ELSEVIER, 2012)
This article discusses conceptual and empirical elements concerning the development of cognitive processes that function as precursors of reading, and their association with the acquisition of reading skills in an adult ...
Attainment of lead titanate - Through the thermal decomposition of coprecipitated 8-hydroxyquinolinate precursors
(Kluwer Academic Publ, 2004-01-01)
Crystalline PbTiO3 was obtained through the thermal decomposition of 8-hydroxyquinolinate of lead(II) and that of titanium(IV), which was monitored by TG/DTG/DTA under different atmospheric conditions and with varying ...
The role of citrate precursors on the morphology of lanthanide oxides obtained by thermal decomposition
(SPRINGER, 2010)
Two series of lanthanide oxides with different morphologies were synthesized through calcinations of two types of citrate polymeric precursors. These oxides were characterized by XRD patterns, SEM electronic microscopy, ...
