Synthesis and biological evaluation of 5-substituted derivatives of benzimidazole
(Serbian Chemical Soc, Belgrade, 2014)
A series of eight novel 5-substituted derivatives of benzimidazole was synthesized by condensation of the corresponding diamine with ethyl 4-[4-(2-chlorophenyl)piperazin-1-yl]butanoate in refluxing 4 M hydrochloric acid. ...
Electrochemical Oxidation of Methanol and Ethanol on Electrodeposited Pd and PdNi-Coated Electrodes
(Pleiades Publishing Inc, Moscow, 2017)
Electrodeposited PdNi and Pd samples were tested for methanol and ethanol oxidation reaction (MOR and EOR) in alkaline solution using cyclic voltammetry (CV) and chronoamperometric (CA) measurements. Among the CVs for the ...
Porous glycidyl methacrylate-bentonite composite
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Crosslinked macroporous copolymer of glycidyl methacrylate and ethylene glycol dimethacrylate (CP) and copolymer composite with acid modified clay (CP-S-A) were prepared by radical suspension copolymerization and functionalized ...
A trapezoidal microstrip bandstop filter with efficient suppression of undesired stopbands
(National Institute of Optoelectronics, 2010)
A new bandstop filter implemented as a cascade of trapezoidally shaped cells is presented. The proposed bandstop filter suppresses many undesired stopbands at higher frequencies. The cell design is specified by two variables ...
Polyphenolic compounds in seeds from some grape cultivars grown in Serbia / Polifenolna jedinjenja iz semenki osam sorti grožđa gajenih u Srbiji
(Serbian Chemical Soc, Belgrade, 2010)
Seed extracts from eight grape cultivars (Vitis vinifera) growing in Serbia were screened for their polyphenolic composition by means of HPLC/ /PDA/ESI/MS analysis. The study revealed 34 phenolic compounds belonging to the ...
Oxidation of hydroxide ions at platinum-modified zeolite electrode / Izvod oksidacija hidroksilnih jona na zeolitu modifikovanom platinom
(Association of Chemical Engineers of Serbia, 2012)
NaX zeolite was modified by platinum via impregnation/thermal decomposition technique, using Pt(II)-acetyl acetonate in acetone as an impregnating solution. The samples were characterized by scanning electron microscopy ...
Secondary lipid oxidation products of oil in white mustard seeds (sinapis albae semen)
(Scibulcom Ltd, Sofia, 2013)
In this study secondary lipid oxidation products of oil in white mustard seeds were analysed. Ground white mustard seeds were extracted by solvent extraction and the extract was analysed by gas chromatographic-mass ...
Intrinsic Distortion Path in the analysis of the Jahn-Teller effect
(Elsevier, 2010)
The multideterminental-DFT approach was performed in order to calculate the Jahn-Teller (JT) parameters for the JT active molecules. Within the harmonic approximation the JT distortion can be analysed as a linear combination ...
Gentiana lutea Extracts and their Constituents as Inhibitors of Synaptosomal Ecto-NTPDase
(Asian Network Scientific Information-Ansinet, Faisalabad, 2016)
The extracellular nucleotides act as neurotransmitters and signaling molecules in CNS, binding to a P2X and P2Y receptors. Their concentration regulates a cascade of membrane ecto enzymes, including the ecto-nucleotide ...
Effect of the electrolysis regime on the structural characteristics of honeycomb-like electrodes
(Soc Chemists Technologists Madeconia, Skopje, 2013)
The effect of different current regimes of electrolysis on the micro- and nanostructural characteristics of open porous structures was examined by the analysis of honeycomb-like copper electrodes obtained by constant ...
