Morphological evolution of zinc oxide originating from zinc hydroxide carbonate
Zinc oxide can be obtained by thermal decomposition of hydrozincite, a topochemical reaction. This work reports the relation between zinc oxide morphology and the precursor zinc hydroxide carbonate precipitation time. The ...
Luminescent properties and lattice defects correlation on zinc oxide
(Elsevier B.V., 2001-11-01)
The ZnO luminescent properties are strongly influenced by the preparation method and they are principally related to electronic and crystalline structures. This work reports about the correlation among luminescence properties ...
Study of crystallite size and strain as a function of morphological evolution in zinc oxide powder obtained from hydroxycarbonate precursor
In this work, zinc oxide samples were obtained from hydroxycarbonate by thermal decomposition at 300°C. Zinc hydroxycarbonate samples were produced by homogeneous precipitation over different periods of time. The method ...
Biodisponibilidade de fontes orgânicas e inorgânicas de zinco em ovinos
(Arquivo Brasileiro Medicina Veterinaria Zootecnia, 2011-04-01)
This research was done to compare the effects of different zinc sources and doses in the Santa Ines sheep diet. Forty lambs at weaning, with 18,4kg BW were randomly allotted and fed 10 treatments: 1- base diet without zinc ...

ZnO-TiO2 composite formed by mixed oxides via polyol
(Trans Tech Publications Ltd, 2012-01-01)
Among the researches on preparation and test of nanostructured materials, titanium dioxide and zinc oxide have been the most frequent studied oxides. In order to extend their properties, composites have been prepared using ...
Novel solid-state route to nanostructured tin, zinc and cerium oxides as potential materials for sensors
(American Scientific Publishers, 2014)
© 2014 American Scientific Publishers.Solid-state sensor nanostructured materials (SnO2, ZnO and CeO2) have been prepared by pyrolysis of macromolecular complexes: PSP-co-4-PVP · (SnCl2)n, PSP-co-4-PVP · (ZnCl2)nand ...
