Discovery of uranium mineralizations in the rhyolite-granite complex in the Jabal Eghei area of southern Libya
(Journal of the Serbian Chemical Society, 2013)
During an investigation of the Jabal Eghei area in southern Libya and the production of geological maps on a scale of 1:250 000 (Tibesti sector, sheet Wadi Eghei NF 34-1 and NF 34-2), regional prospecting for mineral raw ...
Determination of surface coverage of iron-phosphate coatings on steel using the voltammetric anodic dissolution technique
(Journal of the Serbian Chemical Society, 2013)
In this study, the effect of deposition time and concentration of NaNO2 in the phosphate bath on the surface morphology of iron-phosphate coatings on low carbon steel was investigated using scanning electron microscopy ...
Influence of the content of hard segments on the properties of novel urethane-siloxane copolymers based on a poly(epsilon-caprolactone)-b-poly(dimethylsiloxane)-b-poly(epsilon-caprolactone) triblock copolymer
(Journal of the Serbian Chemical Society, 2011)
A series of novel thermoplastic urethane-siloxane copolymers (TPUSs) based on a alpha,omega-dihydroxy-[poly(epsilon-caprolactone)-b-poly(dimethylsiloxane)-b-poly(epsilon-caprolactone)] (alpha,omega-dihydroxy-PCL-PDMS-PCL) ...
Analysis of the bioavailability of Cr(III) and Cr(VI) based on the determination of chromium in Mentha piperita by graphite furnace atomic absorption spectrometry
(Journal of the Serbian Chemical Society, 2011)
Mentha piperita L. (Lamiaceae) was cultivated under the controlled laboratory conditions in the presence of varying levels of trivalent and hexavalent chromium in order to determine its capacity to control chromium uptake ...
Electrochemical synthesis of silver nanoparticles in poly(vinyl alcohol) solution
(Journal of the Serbian Chemical Society, 2013)
In this work, silver/poly(vinyl alcohol), Ag/PVA, colloidal dispersions were obtained by electrochemical reduction of Ag+. The electrochemical synthesis of silver nanoparticles in aqueous solutions of 5 and 10 wt. % PVA, ...
Synthesis and crystal structure of Cu(II) and Co(II) complexes with the 1,3-dimethylpyrazole-5-carboxylic acid ligand
(Journal of the Serbian Chemical Society, 2015)
In the reaction of 1,3-dimethylpyrazole-5-carboxylic acid (HL) with M(OAc)(2)center dot 4H(2)O, (M = Cu or Co), two novel complexes were prepared, the square-planar [CuL2(H2O)(2)] and the octahedral [CoL2(MeOH)(4)]. The ...
Stereospecific ligands and their complexes. Part XIV. Crystal structure of the O,O -dipropyl ester of N,N -1,2-ethanediylbis-L-leucine, dihydrochloride

The bidentate N,N-ligand precursor, the O,O-dipropyl ester of N,N,N-1,2-ethanediyIbis-L-leucine, dihydrochloride, [(S,S)-H(4)eddl]Cl-2, was prepared and its crystal structure is given herein. It crystallizes in a P4(2) ...
Novel negatively charged membrane adsorbers made using a combination of photopolymerization and immersion precipitation
(Journal of the Serbian Chemical Society, 2016)
A novel method combining a traditional immersion precipitation process for making membranes with photopolymerization and crosslinking of functional monomers included in the casting solution was used to prepare asymmetric ...
Stability of zirconia sol in the presence of various inorganic electrolytes
(Journal of the Serbian Chemical Society, 2013)
The zirconia sol was prepared from a zirconium oxychloride solution by forced hydrolysis at 102 degrees C. The prepared sol consisted of almost spherical, monoclinic, hydrated zirconia particles of 61 nm in diameter. The ...
The influence of chemical and thermal treatment on the point of zero charge of hydrous zirconium oxide
(Journal of the Serbian Chemical Society, 2013)
Two zirconia samples were prepared by precipitation from aqueous zirconium oxychloride and zirconyl sulfate solutions with potassium hydroxide. The prepared zirconia samples were amorphous. The pH(pzc) values of the zirconia ...
