Structural, Magnetic, DFT, and Biological Studies of Mononuclear and Dinuclear Cu-II Complexes with Bidentate N-Heteroaromatic Schiff Base Ligands
(Wiley-V C H Verlag Gmbh, Weinheim, 2015)
Copper(II) complexes with the condensation derivative of methyl hydrazinoacetate and 2-acetylpyridine were synthesized. The X-ray crystal structures for both complexes revealed that they are polymerized isomers. A common ...
In vitro evaluation of cytotoxic and mutagenic activity of avarol
(Taylor & Francis Ltd, Abingdon, 2016)
The cytotoxicity of avarol, a main secondary metabolite of the Mediterranean sponge Dysidea avara, was in vitro screened by MTT assay against four human tumour cell lines. The colon HT-29 tumour cells practically showed ...
Electrodeposited AgPd alloy coatings as efficient catalysts for the ethanol oxidation reaction
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
The Pd and three AgPd alloy layers (AgPd1, AgPd2 and AgPd3) were electrodeposited onto Au disc electrodes from the solution containing high concentration of chloride ions (>12 M). All coatings were investigated by scanning ...
Influence of starting powder milling on magnetic properties of Mn-Zn ferrite
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2017)
In this paper, the influence of additional sieving and milling of starting industrial Mn-Zn powders on magnetic properties was investigated. The starting powder was milled for 60 minutes, followed by sieving through 325 ...
Long-term passive restoration following fluvial deposition of sulphidic copper tailings: nature filters out the solutions
(Springer Heidelberg, Heidelberg, 2016)
Despite the growing popularity of ecological restoration approach, data on primary succession on toxic post-mining substrates, under site environmental conditions which considerably differ from the surrounding environment, ...
Concentrations of 18 Elements in Muscle, Liver, Gills, and Gonads of Sichel (Pelecus cultratus), Ruffe (Gymnocephalus cernua), and European Perch (Perca fluviatilis) in the Danube River near Belgrade (Serbia)
(Springer International Publishing Ag, Cham, 2015)
The analysis of 18 elements in muscle, liver, gills, and gonads of sichel (Pelecus cultratus), ruffe (Gymnocephalus cernua), and European perch (Perca fluviatilis), caught at a polluted segment of the Danube River near ...
Electrochemical lithiation/delithiation kinetics and capacity of phosphate tungsten bronze and its chemically pre-lithiated derivatives in aqueous solutions
(Springer, New York, 2016)
Monophosphate bronze (PW8O26, WPB) was synthesized by low-temperature (650 A degrees C) heating of 12-tungstophosphoric acid (WPA). Its lithiated derivative with a low lithium content (Li-3-WPB) was synthesized by heating ...
Composition of Anthocyanins in Colored Grains and the Relationship of Their Non-Acylated and Acylated Derivatives
(Inst Animal Reproduction & Food Research Polish Acad Sciences Olsztyn, Olsztyn, 2019)
Colored grains are rich sources of anthocyanins that could play an important role in the prevention of various diseases associated with oxidative stress. Bearing in mind that cereals are widely grown crops, anthocyanins-rich ...
Reheating of Zinc-titanate Sintered Specimens
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2015)
The scope of this work was observing dimensional and heat transfer changes in ZnTiO3 samples during heating in nitrogen and air atmosphere. Interactions of bulk specimens with gaseous surrounding induce microstructure ...
Thermal diffusivity and electron transport properties of NTC samples obtained by the photoacoustic method
(Elsevier Science Sa, Lausanne, 2006)
Thermal diffusivity and electron transport parameters of sintered NTC samples were determined by the photoacoustic (PA) technique. Powder mixtures composed of MnO, NiO, CoO and Fe2O3 were milled to nanometer particle size. ...
