Structure, microstructure, ferroelectric/electromechanical properties and retention characteristics of [Bi1-x Nb (x) ]FeO3 thin films
(Springer, 2012-11-01)
In this work, we report the structure, microstructure, ferroelectric/electromechanical properties, and retention characteristics of [Bi1-x Nb (x) ]FeO3 (BNFO) thin films [x=0,0.025,0.05, and 0.1] prepared by the polymeric ...
Photoluminescent behavior of SrBi2Nb2O9 powders explained by means of beta-Bi2O3 phase
(American Institute of Physics (AIP), 2007-06-25)
Photoluminescence (PL) behavior of SrBi2Nb2O9 (SBN) powders was explained by means of beta-Bi2O3 phase on the SBN lattice. Oxygen vacancies and recombination of electrons holes in the valence band lead to the formation of ...

The VMC survey. XI. Radial stellar population gradients in the galactic globular cluster 47 Tucanae
(IOP Publishing, 2014-07)
We present a deep near-infrared color-magnitude diagram of the Galactic globular cluster 47 Tucanae, obtained with the Visible and Infrared Survey Telescope for Astronomy (VISTA) as part of the VISTA near-infrared Y, J, K ...
Melting and freezing of spherical bismuth nanoparticles confined in a homogeneous sodium borate glass
(AMER PHYSICAL SOC, 2008)
The melting temperature and the crystallization temperature of Bi nanoclusters confined in a sodium borate glass were experimentally determined as functions of the cluster radius. The results indicate that, on cooling, ...
Genotype×production environment interaction for weaning weight in Angus populations of Brazil and Uruguay
(2013-02-01)
The objective of this study was to define production environments by grouping different environmental factors and, consequently, to assess genotype by production environment interactions on weaning weight (WW) in the Angus ...

Microwave-Driven Hexagonal-to-Monoclinic Transition in BiPO4: An In-Depth Experimental Investigation and First-Principles Study
(2020-06-01)
Present theoretical and experimental work provides an in-depth understanding of the morphological, structural, electronic, and optical properties of hexagonal and monoclinic polymorphs of bismuth phosphate (BiPO4). Herein, ...
O desenvolvimento de nanopartículas de intermetálicos ordenados de ouro e estudo da atividade eletroquímica da reação de oxidação do glicerol
(Universidade Estadual Paulista (Unesp), 2015-02-27)
In the present work, we studied the oxidation reaction of glycerol, in alkaline medium (KOH), on the surface of Au/C, AuSn/C e Au2Bi/C materials, synthesized by microemulsion, and Au/Sn/C and Au2Bi/C, by reduction of polyol. ...
Growth and Melting of Metallic Nanoclusters in Glass: A Review of Recent Investigations
(MAIK NAUKA/INTERPERIODICA/SPRINGER, 2008)
The mechanisms of nucleation and growth and the solid-to-liquid transition of metallic nanoclusters embedded in sodium borate glass were recently studied in situ via small-angle X-ray scattering (SAXS) and wide-an-le X-ray ...
