The thermal, rheological and structural properties of cassava starch granules modified with hydrochloric acid at different temperatures
(Thermochimica Acta, 2013-01-20) [Artigo]
Starch is arguably one of the most actively investigated biopolymer in the world. In this study, the native (untreated) cassava starch granules (Manihot esculenta, Crantz) were hydrolyzed by standard hydrochloric acid ...
Structural and electrical properties of LaNiO3 thin films grown on (100) and (001) oriented SrLaAlO4 substrates by chemical solution deposition method
(Ceramics International, 2013-09-01) [Artigo]
LaNiO3 thin films were deposited on SrLaAlO4 (1 0 0) and SrLaAlO4 (0 0 1) single crystal substrates by a chemical solution deposition method and heat-treated in oxygen atmosphere at 700° C in tube oven. Structural, ...
Cation distribution and magnetic characterization of the multiferroic cobalt manganese Co2MnO4 spinel doped with bismuth
(Journal of Magnetism and Magnetic Materials, 2013-03-01) [Artigo]
The structural and magnetic properties of the cubic spinel oxide Co 2MnO4 (Fd3m space group) doped with different concentrations of bismuth, were investigated by X-ray diffraction and SQUID magnetometry. The Bi3+ ions ...
Morphological modifications and surface amorphization in ZnO sonochemically treated nanoparticles
(Ultrasonics Sonochemistry, 2013-05-01) [Artigo]
Application of nanoscale materials in photovoltaic and photocatalysis devices and photosensors are dramatically affected by surface morphology of nanoparticles, which plays a fundamental role in the understanding of the ...
Deposition and photo-induced electrical resistivity of dip-coated NiO thin films from a precipitation process
(Journal of Materials Science: Materials in Electronics, 2013-06-01) [Artigo]
Thin films of the semiconductor NiO are deposited using a straightforward combination of simple and versatile techniques: the co-precipitation in aqueous media along with the dip- coating process. The obtained material is ...
Nanoparticle characterization of Er-doped SnO2 pellets obtained with different pH of colloidal suspension
(Journal of Applied Physics, 2013-08-28) [Artigo]
SnO2:2 at. %Er xerogel samples were obtained by sol-gel technique from colloidal suspensions with distinct pHs. The evaluation of critical regions inside the nanocrystallite is fundamental for the interpretation of the ...
