The molecular properties of nitrobenzanthrone isomers and their mutagenic activities
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
The mutagenic activity of five mono-substituted nitrobenzanthrones (NBA) has been determined in the Ames assay (Takamura-Enya et al., 2006). In the present study, a theoretical investigation of the electronic properties ...
Synthesis, Characterization, and Electrochemistry of Nanotubular Polypyrrole and Polypyrrole-Derived Carbon Nanotubes
(American Chemical Society (ACS), 2014)
Polypyrrole nanotubes (PPy-NTs) were prepared by the oxidation of pyrrole with iron(III) chloride in the presence of a structure-guiding agent, methyl orange. Upon carbonization of the salt form of PPy-NTs, the conducting ...
Development of the production of lead and precious metals in Central Asia / Razvoj proizvodnje olova i plemenitih metala u centralnoj Aziji
(Serbia : Faculty of Mining and Geology, Belgrade, 2014)
There were several rich deposits of polymetal ores of non-ferrous and
precious metals in the region of Imperial Russia and the Soviet Union.
Metallurgical production of these metals was developed even a thousand years
ago ...
Correlation study of retention data and antimalarial activity of 1,2,4,5-mixed tetraoxanes with their molecular structure descriptors and LSER parameters
(Elsevier, 2014)
The chromatographic behavior of mixed 1,2,4,5-tetraoxanes, cholic and deoxycholic acid derivatives with distinct biological activity, was examined by high-performance thin-layer chromatography in order to correlate their ...

Natural and anthropogenic factors affecting the groundwater quality in Serbia
(Elsevier, 2014)
Various chemometric techniques were used to analyze the quality of groundwater data sets. Seventeen water quality parameters: the cations Na, K, Ca, Mg, the anions Cl, SO4, NO3, HCO3 and nine trace elements Pb, As, Mn, Ni, ...
The influence of different radiopacifying agents on the radiopacity, compressive strength, setting time, and porosity of Portland cement
(Springer Heidelberg, Heidelberg, 2014)
The aims of this study were to evaluate the radiopacity, compressive strength, setting time, and porosity of white Portland cement (PC) with the addition of bismuth oxide (Bi2O3), zirconium dioxide (ZrO2), and ytterbium ...
Dietary polysaccharide extracts of Agaricus brasiliensis fruiting bodies: chemical characterization and bioactivities at different levels of purification
(Elsevier, 2014)
Polysaccharides of the European strain of A. brasiliensis were obtained by hot water extraction and ethanol precipitation (HWPE I) of fruiting bodies, and further purified by dialysis (HWPE II) and pronase incubation (PPE). ...
Formic Acid Oxidation at Platinum-Bismuth Clusters
(Electrochemical Soc Inc, Pennington, 2014)
Formic acid oxidation was studied on platinum-bismuth deposits on glassy carbon (GC) substrate. The catalysts of equimolar ratio were prepared by potentiostatic deposition using chronocoulometry. Bimetallic structures ...
Removal of Tc-99(VII) by organo-modified bentonite
(Elsevier, 2014)
(99)Technetium is one of the largest components of nuclear waste material. In aqueous solutions Tc-99 is present as the pertechnetate oxoanion, (TcO4-)-Tc-99, which is highly soluble and mobile in groundwater under oxidizing ...
