Silver/polystyrene nanocomposites: Optical and thermal properties
(Wiley-Blackwell, Hoboken, 2012)
Nanocomposites consisted of different quantities of silver (Ag) nanoparticles incorporated in a polystyrene (PS) matrix have been prepared by solution mixing method. Transmission electron microscopy was applied to determine ...
Effect of parameters of square-wave pulsating current on copper electrodeposition in the hydrogen co-deposition range
(Elsevier Science Inc, New York, 2010)
Copper electrodeposition processes in the hydrogen co-deposition range by the pulsating current (PC) regime were examined by the determination of the average current efficiency of hydrogen evolution and by the scanning ...
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 ...
Biomarker and micropetrographic investigations of coal from the Krepoljin Brown Coal Basin Serbia
(Elsevier, 2013)
We investigated early diagenetic processes of the extractable organic matter from the Miocene freshwater sequence, which consists of coal fragments in clays, sandstones and shales alternating with continuous brown coal ...
Razvoj novih antikorozivnih organo-metalnih jedinjenja na bazi Cerijuma za primenu u alkidnim premazima
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, Beograd, 2019)
Inhibitori korozije su posebna grupa supstanci ili njihovih smeša koje imaju ulogu da spreče ili da minimiziraju koroziju. Sintetisana su tri kompleksa cerijuma: Ce-cisteina, Ce-tanina i Ce-EDTA i pripremenje su ...
Group-Delay-Controlled Multiple-Resonator-Based Harmonic Analysis
(Institute of Electrical and Electronics Engineers Inc., 2017)
In this paper, a modified and improved approach to the recently proposed multiple-resonator-based observer structure for harmonic estimation has been proposed. In the previous papers, two inherent particular cases have ...
Interactive Catalytic Performances of Carbonaceous Materials in Electrochemistry
(New York, USA : Nova Science Publishers Inc., 2019)
The attraction of carbon as an electrode material arises from its unique chemical and physical properties: high conductivity, good corrosion resistance, high temperature stability, high surface-area range (∼1 to >2000 m2 ...
Noncovalent bonding: Stacking interactions of chelate rings of transition metal complexes
(Elsevier Science Sa, Lausanne, 2017)
Analysis of crystal structure data deposited in the Cambridge Structural Database (CSD) has shown that aromatic rings tend to stack with square planar transition metal complexes when they contain chelate rings. In these ...
Palladium(II) complexes with R(2)edda derived ligands. Part IV. O,O '-dialkyl esters of (S,S)-ethylenediamine-N,N '-di-2-(4-methyl)-pentanoic acid dihydrochloride and their palladium(II) complexes: Synthesis, characterization and in vitro antitumoral acti
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2010)
Four novel bidentate N,N'-ligand precursors, including O,O'-dialkyl esters (alkyl = ethyl, n-propyl, n-butyl and n-pentyl), L1 center dot 2HCl-L4 center dot 2HCl, of (S,S)-ethylenediamine-N,N'-di-2-(4-methyl)-pentanoic ...
Catalysis of oxygen reduction on electrochemically activated polycrystalline gold by Pd nanoislands in alkaline solution
(Elsevier, 2017)
Catalytic properties of electrochemically activated polycrystalline gold, Au(poly), modified by spontaneously deposited palladium nanoislands with the coverage below a monolayer were examined for the oxygen reduction ...
