Investigation of interactions between surface water and petroleum-type pollutants
(Ecomed Publishers, Landsberg, 2005)
Background, Aims and Scope. In oil spill investigations, one of the most important steps is a proper choice of approaches that imply an investigation of samples taken from different sedimentary environments, samples of oil ...
Toluene Degradation in Water Using AlFe-Pillared Clay Catalysts
(Science Press, Beijing, 2009)
The catalytic wet peroxide oxidation (CWPO) of toluene on two bentonite-based AlFe-pillared clays (PILCs) with different iron contents was investigated. The PILCs were obtained using bentonite clay from Bogovina, Serbia. ...
The inhibiting effect of cobalt(III)-cyclam complexes with substituted β-diketones on iron corrosion in perchlorate solution
(Journal of Solid State Electrochemistry, 2008)
The inhibiting effect of cobalt(III) complexes with macrocyclic ligand cyclam (1,4,8,11-tetraazacyclotetradecane) and β-diketonato ligands have been investigated on iron corrosion in 0.1 M HClO 4 by potentiodynamic, linear ...
Organic-geochemical differentiation of petroleum-type pollutants and study of their fate in Danube alluvial sediments and corresponding water (Pancevo Oil Refinery, Serbia)
(Springer, 2007)
A review is given in this paper of the up-to-date results observed in differentiation and transformation studies on petroleum-type pollutants in underground and surface waters. Water and particulate matter derived from the ...
X-ray analyses, spectroscopic and magnetic properties of [Cu4(succinato)(tpmc)2](ClO4) 6·2C2H5OH·4H2O and [Cu2(C6H5COO)tpmc](ClO4) 3·0.5CH3OH·0.5H2O complexes
(Elsevier, 2008)
[Cu4(succinato)(tpmc)2](ClO4) 6 · 2H2O (tpmc = N,N′,N″,N‴-tetrakis-(2-pyridylmethyl)-1,4,8,11-tetraa zacyclotetradecane, succinato = dianion of succinic acid) has been prepared and characterized by elemental analysis, ...
Volatile constituents of Achillea serbica Nym.
(John Wiley and Sons Ltd, 2000)
The volatile constituents of Achillea serbica Nym. (Asteraceae), an endemic plant of the Balkan Peninsula, has been analysed using GC and CC-MS. Fifteen identified components constituted 95.7% of the oil. The major fractions ...
Purification and properties of midgut α-amylase isolated from Morimus funereus (Coleoptera: Cerambycidae) larvae
(Elsevier Science Inc, New York, 2008)
Using soluble starch as a substrate five isoforms of α-amylase were identified in a crude extract of Morimus funereus larvae. The main α-amylase (termed AMF-3) was purified by gel filtration chromatography and anion exchange ...
Different responses of mesenteric artery from normotensive and spontaneously hypertensive rats to nitric oxide and its redox congeners
(Springer, 2007)
The conversion of nitric oxide (NO
) into its congeners nitrosonium (NO ) and nitroxyl (HNO/NO) ions may have important consequences for signal transduction and physiological responses. Manganese-containing superoxide ...
Stereochemistry and conformations of natural 1,2-epoxy-guaianolides based on 1D and 2D NMR data and semiempirical calculations
(Magnetic Resonance in Chemistry, 2008)
From detailed study of ID and 2D NMR spectra of ten natural 1,2-epoxyguaianolides (bis-1,2:3,4-epoxyguaianolides and guaianolide-1,2- epoxychlorohydrins), we identified general spectral traits helpful for stereochemical ...
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 ...
