Two O2 If*/WN6 stars possibly ejected from the massive young Galactic cluster Westerlund 2
(Oxford University Press, 2011-09)
In this paper we report the identification of two new Galactic O2 If*/WN6 stars (WR20aa and WR20c), on the outskirts of the massive young stellar cluster Westerlund 2. The morphological similarity between the near-infrared ...
Optical, electrical and structural characterization of chloridedoped ZnO nanopillars obtained by electrodeposition
(IOP Publishing, 2016-05-03)
As-grown and chloride-doped ZnO nanopillars were electrodeposited onto bareFTO/glass and ZnO-compact layer/FTO/glass substrates. To analyse the effect of the presence of chloride ions in the electrolytic bath, NH4Cl was ...
Interaction of bovine serum albumin (BSA) with ionic surfactants evaluated by electron paramagnetic resonance (EPR) spectroscopy
(ELSEVIER SCIENCE BV, 2009)
EPR spectra of 5- and 16-doxyl stearic acid nitroxide probes (5-DSA and 16-DSA, respectively) bound to bovine serum albumin (BSA) revealed that in the presence of ionic surfactants, at least, two label populations coexist ...
Structural refinement and photoluminescence properties of irregular cube-like (Ca1−xCux)TiO3 microcrystals synthesized by the microwave–hydrothermal method
(ElsevierLausanne, 2012-09)
In this paper, calcium copper titanate (Ca1−xCux)TiO3 microcrystals with (x = 0, 0.01 and 0.02) were synthesized by the microwave–hydrothermal method at 140 °C for 30 min. These crystals were analyzed by X-ray diffraction ...
A Burst with Double Radio Spectrum Observed up to 212 GHz
(Springer, 2013-06)
We study a solar flare that occurred on 10 September 2002, in active region NOAA 10105, starting around 14:52 UT and lasting approximately 5 minutes in the radio range. The event was classified as M2.9 in X-rays and 1N in ...
Pd-γAl2O3 applied to triglycerides hydrogenation with supercritical propane. Experimental and theoretical catalysts characterization
(Elsevier Science, 2008-09)
A set of Pd-γAl2O3 catalysts of different metallic particle sizes and modified with 2-chloro-butane was used for triglyceride hydrogenation. The experiments were carried out in single-phase conditions using propane as a ...
Pd-Al2O3 Applied to the Hydrogenation of Tryglicerides with Supercritical Propane. Experimental and Theoretical Characterization of Catalysts
(Elsevier Science, 2008-12)
A set of Pd-Al2O3 catalysts of different metallic particle sizes and modified with 2-chloro-butane was used for triglyceride hydrogenation. The experiments were carried out in single-phase conditions using propane as a ...
Detection of X-rays from the jet-driving symbiotic star Hen 3-1341
(Edp Sciences, 2013-06)
Context. Hen 3-1341 is a symbiotic binary system consisting of a white dwarf and a red giant star that is one of about ten symbiotics that show hints of jets. The bipolar jets have been detected through displaced components ...
Properties of soluble α-chymotrypsin in neat glycerol and water
(Elsevier Science Inc, 2000-12)
UV scanning of a-chymotrypsin dissolved in neat glycerol and water showed no significant differences in its spectra at pH 7.8. Fluorescence scanning revealed a strong dependence on pH values (between 5.9 to 10.5) of the ...
