A Base Promoted Cyclization of N-Propargylaminopyridines. Synthesis of Imidazo[1,2-a]pyridine Derivatives
(American Chemical Society (ACS), 2011)
A base promoted cyclization of the protected N-propargylaminopyridines was shown to be an efficient method for the preparation of imidazo[1,2-a] pyridine derivatives. The reactions were carried out with a small excess of ...
Synthesis, characterization, cytotoxic activity and DNA binding properties of the novel dinuclear cobalt(III) complex with the condensation product of 2-acetylpyridine and malonic acid dihydrazide
(Elsevier Science Inc, New York, 2011)
A novel dinuclear cobalt(III) complex with the condensation product of 2-acetylpyridine and malonic acid dihydrazide, N',N'(2)-bis[(1E)-1-(2-pyridyl)ethylidene]propanedihydrazide was synthesized and characterized by elemental ...
A study of trace element contamination in river sediments in Serbia using microwave-assisted aqua regia digestion and multivariate statistical analysis
(Elsevier, 2011)
The aim of this study was the evaluation of the trace element contamination level in sediments of the most important rivers in Serbia and their tributaries. The determination of the aqua regia soluble contents of 12 micro- ...
Aqua regia extracted metals in sediments from the industrial area and surroundings of Pancevo, Serbia
(Elsevier, 2011)
Surface and buried sediments were analyzed for Ba, Ca, Cd, Co, Cr, Cu, Mn. Ni, Pb, Zn and V. as well as for total carbon and hydrogen to assess the distribution of sediment pollution due to the vicinity of the petrochemical ...
Corrosion stability of polyester coatings on steel pretreated with different iron-phosphate coatings
(Elsevier Science Sa, Lausanne, 2011)
The influence of steel surface pretreatment with different types of iron-phosphate coatings on the corrosion stability and adhesion characteristics of polyester coatings on steel was investigated. The phosphate coating was ...
Simultaneous Determination of Pb and Cd Traces in Water Samples by Anodic Stripping Voltammetry Using a Modified GC Electrode
(Wiley-Blackwell, Malden, 2011)
The determination of Pb and Cd with a Nafion-modified glassy carbon electrode and Cu-DPABA complex (Cu-DPABA NA/GCE; DPABA is methyl 3,5-bis{bis-[(pyridin-2-yl)methyl]amino}methyl-benzoate) as an alternative electrode for ...
Influence of process parameters on the photodegradation of synthesized azo pyridone dye in TiO2 water suspension under simulated sunlight
(Taylor and Francis Inc., 2011)
Photocatalytic degradation of synthesized azo pyridone dye (5-(4-sulpho phenylazo)-6-hydroxy-4-methyl-3-cyano-2-pyridone), in aqueous solutions by simulated sunlight in the presence of commercial TiO2, Aeroxide P25, was ...
Microstructure and corrosion behaviour of Zn-Co alloys deposited from three different plating baths / Mikrostruktura i koroziono ponašanje Zn-Co legura taloženih iz sulfatnog i hloridnih rastvora
(Serbian Chemical Society, 2011)
The effects of plating baths of different composition on the micro- structure and corrosion stability of Zn-Co alloy coatings were studied. Zn-Co alloys with the same Co content were deposited from chloride plating baths ...
Initial corrosion protection of Zn-Mn alloys electrodeposited from alkaline solution
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
The effects of a deposition current density (c.d.) on the corrosion behaviour of Zn-Mn alloy coatings, deposited from alkaline pyrophosphate solution, were investigated by atomic absorption spectrophotometry (AAS), X-ray ...
Contribution of Non-Canonical Interactions to the Stability of Sm/LSm Oligomeric Assemblies
(Wiley-V C H Verlag Gmbh, Weinheim, 2011)
The distinguishing property of Sm/LSm protein assemblies is their high stability. In order to better understand the nature of Sm/LSm protein oligomers in this study we have analyzed the contribution of non-canonical ...
