Ni-Sn coatings as cathodes for hydrogen evolution in alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
In this work the hydrogen evolution reaction (HER) at Ni-Sn alloy coatings, deposited onto Ni 40 mesh at different current densities from the bath containing 0.1 mol dm(-3) SnCl2 + 0.3 mol dm(-3) NiCl2 in the pyrophosphate-glycine ...
Pollen morphology, viability, and germination of Prunus domestica cv. Pozegaca
(Elsevier, Amsterdam, 2013)
The pollen morphology and exine ornamentation of an important autochthon plum cultivar (Prunus domestica cv. Pozegaca L), which has horticultural, medicinal and alimentary uses, was examined in detail using both light and ...
Ni-moo2 cathodes for hydrogen evolution in alkaline solutions. Effect of the conditions of their electrodeposition
(International Association of Physical Chemists, 2013)
The electrodeposition of Ni-MoO2 composite coatings is a specific process taking place under defined hydrodynamic conditions. In this work the influence of hydrodynamics, current density, and MoO2 concentration on the ...
Changes in the antioxidative metabolism induced by drought and cd excess in the leaves of houseleek (sempervivum tectorum l.)
(Fresenius Environmental Bulletin, 2013)
House leek (Sempervivum tectorum L.), as a succulent CAM plant, withstands great water stress due to a CO2-concentrating mechanism. It is traditionally used as a medical plant, partly due to high foliar concentrations of ...
Membrane Fluidity, Invasiveness and Dynamic Phenotype of Metastatic Prostate Cancer Cells after Treatment with Soy Isoflavones
(Springer, New York, 2013)
Soy isoflavones represent hopeful unconventional remedies in the therapy of prostate cancer. The aim of our study was to determine the effects of genistein and daidzein on the parameters that reflect metastatic potential, ...
Influence of the complex formation on the morphology of lead powder particles produced by the electrodeposition processes
(Elsevier Science Bv, Amsterdam, 2013)
The processes of lead electrodeposition from the basic (nitrate) and complex (acetate) electrolytes were mutually compared by the analysis of their polarization characteristics and by the scanning electron microscopic (SEM) ...
Influence of the type of electrolyte on the morphological and crystallographic characteristics of lead powder particles
(Srpsko hemijsko društvo, Beograd, 2013)
Lead electrodeposition processes from basic (nitrate) and complex (acetate) electrolytes were mutually compared by scanning electron microscopy and X-ray diffraction investigation of the produced powder particles. The shape ...
Distribution and accumulation of elements (As, Cu, Fe, Hg, Mn, and Zn) in tissues of fish species from different trophic levels in the Danube River at the confluence with the Sava River (Serbia)
(Springer Heidelberg, Heidelberg, 2013)
Pikeperch (Sander lucioperca), European catfish (Silurus glanis), common carp (Cyprinus carpio), and gobies (Neogobius gymnotrachelus, Neogobius melanostomus) were collected from the Danube River (Belgrade section), and ...
Ecologically acceptable usage of derivatives of essential oil of sweet basil, Ocimum basilicum, as antifeedants against larvae of the gypsy moth, Lymantria dispar
(Library of the University of Arizona, 2013)
Ethanol solutions of five fractions obtained from essential oil of sweet basil Ocimum basilicum L. (Lamiales: Lamiaceae) (F1-F5) were tested for their antifeedant properties against 2nd instar gypsy moth larvae, Lymantria ...
Stream section types of the Danube River in Serbia according to the distribution of macroinvertebrates
(Springer, New York, 2013)
The aim of this study was to use the data on the distribution of aquatic macroinvertebrates obtained from 14 sites within a 413 km long stretch of the Danube River in Serbia to show the relevance of the bordering zone ...
