Oxygen reduction on Au(111) and vicinal Au(332) faces: A rotating disc and disc-ring study
(Elsevier, 1994)
The kinetics of oxygen reduction on the Au(111) surface in acidic solution has been re-examined by means of a rotating disc electrode technique. Its vicinal Au(332) = Au[6(111) × (111)] surface has been chosen to examine ...
SEM/EDX and XRD characterization of silver nanocrystalline thin film prepared from organometallic solution precursor
(Technical Faculty, Bor-Serbia, Bor, 2013)
The Ag nano-structured thin films prepared on flat glass substrates have been studied. The ball-like silver nanoparticles have been synthesized in large quantity by using a modified method of hydrolytic decomposition of ...
A novel pimara-8(9),15-diene from lycopus europaeus
(Pergamon Press, 1985)
Identification of a novel trioxygenated Δ8(9),15_ pimaric acid methyl ester from plant species Lycopus europaeus by means of two-dimensional 1H NMR spectroscopy (COSY and NOESY) is reported. © 1985.
Characterization of double oxide system Cu-Cr-O supported on gamma-Al2O3
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Series of alumina supported chromium-copper catalysts were prepared by co-impregnation method. The samples were characterized by X-ray diffraction, X-ray photoelectron spectroscopy and UV-visible diffuse reflectance ...
Antioxidant Evaluation of Heterocyclic Compounds by Cytokinesis-Block Micronucleus Assay
(Bentham Science Publ Ltd, Sharjah, 2013)
This article summarizes the results of using cytokinesis-block micronucleus (CBMN) assay to evaluate the antioxidant potential of heterocyclic compounds. Most studies were carried out with naturally occurring heterocyclic ...
Analysis of solid waste from ships and modeling of its generation on the river Danube in Serbia
(Sage Publications Ltd, London, 2013)
This study focuses on the issues related to the waste management in river ports in general and, particularly, in ports on the river Danube's flow through Serbia. The ports of Apatin, Bezdan, Backa Palanka, Novi Sad, Belgrade, ...
The Galvanostatic Reduction on Modified Platinum Electrode and Determination of Trinitrotoluene in Neutral Solution
(Esg, Belgrade, 2013)
The study of the electrochemical reduction on acetonitrile modified platinum electrode and determination of trinitrotoluene (TNT) in neutral solution by simple galvanostatic technique is presented here. The obtained ...
Cohesive energy densities of poly(di‐n‐alkyl itaconates)
(Wiley, 1977)
The solubility parameters of the first ten members of the homologous series of poly(di‐n‐alkyl itaconates) were determined from limiting viscosity numbers in various organic solvents, differing in structure, polarity and ...
Synthesis, characterization and crystal structure of palladium(II) complexes containing edta tetraalkyl ester ligands
(Ceska Republika : Akademie Ved Ceske Republiky, 2007)
The reaction of solutions of tetraalkyl ethylenediamine-N,N,N′, N′-tetraacetate esters (alkyl = Me, 1a; Et, 1b) with H 2[PdCl4] led to the complexes [PdCl2(R 4EDTA)] (R = Me, 2a; Et, 2b). The coordination of R4EDTA ligands ...
New Methods of Obtaining Fuel Cell Electrodes: IV . Powder Electrode Fuel Cell with Lateral Feeding
(USA : American Chemical Society, 1969)
A previously developed powder electrode in combination with lateral feeding with gases has been further improved. A fuel cell without gas chambers and with loose carbon powder electrodes has been constructed and tested ...
