Voltage-composition profile and synchrotron X-ray structural analysis of low and high temperature LixCoO2 host material
(Amer Chemical Soc, 2008-09-18)
In the present work, the intercalation of lithium ions in the LixCoO2 host material was investigated by means of the discharge curves and voltage-composition profile with the main goal of establishing a close correlation ...
Reaction pathway to the synthesis of anatase via the chemical modification of titanium isopropoxide with acetic acid
(Amer Chemical Soc, 2008-01-08)
Anatase nanoparticles were obtained through a modified sol-gel route from titanium isopropoxide modified with acetic acid in order to control hydrolysis and condensation reactions. The modification of Ti(O(i)Pr)(4) with ...
Barium strontium titanate powders prepared by spray pyrolysis
(Elsevier B.V., 2005-09-15)
Ultasonic spray pyrolysis (SP) has been investigated for the production of the barium strontium titanate (BST) powders from the polymeric precursors. The processing parameters, such as flux of aerosol and temperature profile ...
Crystal structure of propylthiouracil determined using high-resolution synchrotron X-ray powder diffraction
(Royal Soc Chemistry, 2011-01-01)
The crystal structure of propylthiouracil, a drug used in the treatment of hyperthyroidism, was determined by means of high-resolution synchrotron X-ray powder diffraction data. The Rietveld method was employed to refine ...
Joint Experimental and Theoretical Analysis of Order Disorder Effects in Cubic BaZrO3 Assembled Nanoparticles under Decaoctahedral Shape
(Amer Chemical Soc, 2011-05-05)
Periodic first-principles calculations based on density functional theory at the B3LYP level has been carried out to investigate the photoluminescence (PL) emission of BaZrO3 assembled nanoparticles at room temperature. ...
The influence of cation segregation on the methanol decomposition on nanostructured SnO2
(Elsevier B.V., 2002-09-20)
Here we describe a new route to synthesize ultrafine rare earth doped and undoped tin oxide particles for catalytic applications. The catalytic behavior observed in SnO2 samples suggests the control of the catalytic activity ...
Effect of partial preferential orientation and distortions in octahedral clusters on the photoluminescence properties of FeWO4 nanocrystals
(Royal Soc Chemistry, 2012-01-01)
This communication is a report of our initial research to obtain iron tungstate (FeWO4) nanocrystals by the microwave-hydrothermal method at 170 degrees C for 45 min. X-ray diffraction patterns showed that the FeWO4 ...
Influence of the morphology and microstructure on the photocatalytic properties of titanium oxide films obtained by sparking anodization in H3PO4
(Pergamon-Elsevier B.V. Ltd, 2011-03-30)
The aim of this paper is to investigate changes in morphology and microstructure of TiO2 films, prepared by sparking anodization of Ti in a H3PO4 solution, by applying different formation charges. We show that although ...
Microstructural and morphological analysis of pure and Ce-doped tin dioxide nanoparticles
(Elsevier B.V., 2003-04-01)
Structural morphological studies in pure and Ce-doped tin dioxide nanoparticles with high stability against particle growth were performed in samples, obtained using the polymeric precursor method and prepared at different ...
