Thermal decomposition and rehydration of strontium oxalate: morphological evolution
(Elsevier B.V., 2001-09-01)
Undoped and Eu3+ doped monohydrate strontium oxalate samples were precipitated under ultrasound and conventional stirring and were heated at different temperatures. All samples were characterized by X-ray powder diffraction ...
Use of strontium in the activation of bovine oocytes reconstructed by somatic cell nuclear transfer
(Cambridge University Press, 2005-11-01)
As an important step in the nuclear transfer (NT) procedure, we evaluated the effect of three different treatments for oocyte activation on the in vitro and in vivo developmental capacity of bovine reconstructed embryos: ...
Activation and early parthenogenesis of bovine oocytes treated with ethanol and strontium
(Elsevier B.V., 2004-03-01)
Efficient artificial activation is indispensable for the success of cloning programs. Strontium has been shown to effectively activate mouse oocytes for nuclear transfer procedures, however, there is limited information ...
Strontium titanate films prepared by spray pyrolysis
(Elsevier B.V., 2004-01-01)
Strontium titanate thin films were prepared by spray pyrolysis technique. Deposition parameters, such as solution concentration, time and temperature of deposition, and flow rate of carrier gas were optimized to obtain ...
Structural phase evolution of strontium-doped lead titanate thin films prepared by the soft chemical technique
(2003-03-01)
Strontium-modified lead titanate thin films with composition Pb1-xSrxTiO3 were grown on Pt/Ti/SiO2/Si substrates using the polymeric precursor method. The structural phase evolution as a function of the Sr contents was ...
Strontium zirconate heterogeneous catalyst for biodiesel production: Synthesis, characterization and catalytic activity evaluation
(Elsevier B.V., 2012-11-28)
Strontium zirconate oxide was synthesized by co-precipitation and the citrate route and was evaluated as a heterogeneous catalyst for biodiesel production. The catalyst samples were characterized by XRD, FTIR, and TG, and ...
A scanning electronic microscopy study of the action of different desensitizing agents on bovine dentin
(2008-07-01)
This study sought to use scanning electronic microscopy (SEM) to evaluate the dentinal tubule occlusion potential of different desensitizing agents. Ten slices of bovine dentin were divided into six fragments, cleaned ...
Influence of desensitizing agents on the microshear bond strength of adhesive systems to dentin.
(2009-09-24)
The aim of this study was to evaluate the effect of desensitizing agents on the micro-shear bond strength of adhesive systems to dentin. Forty bovine teeth were divided into 8 groups (n=5): G1--Single Bond (SB); G2--GH.F ...
Microstructure and phase evolution of SrTiO3 thin films on Si prepared by the use of polymeric precursors
(1997-06-01)
The use of polymeric precursors was employed in preparing SrTiO3 thin films by dip coating using Si (111) as substrate. Crack free films were obtained after sintering at temperatures ranging from 550 to 1000°C. The ...
Synthesis and thermal study of 8-hydroxy-quinoline derivatives of the alkaline Earth metals: I. Strontium complexes
(1999-12-01)
Strontium complexes of 5,7-dibromo-, 5,7-dichloro-, 7-iodo- and 5-chloro-7-iodo-8-hydroxyquinoline were precipitated from an aqueous ammonia and acetone medium. The complexes obtained were Sr[(C9H4ONBr2)2]·2.5H 2O; ...
