Biomarker distributions as indicators for the depositional environment of lacustrine sediments in the Valjevo-Mionica basin (Serbia)
(Elsevier Gmbh, Urban & Fischer Verlag, Jena, 2008)
In this study, the molecular composition and biomarker distribution of lacustrine sediments from Val-1 drillhole in the central zone of the western part of the Valjevo-Mionica basin were investigated at depth interval of ...
Further sesquiterpene lactones from Anthemis carpatica
(Pergamon, 2000)
A new germacranolide, (E)-1α, 10β-epoxy-3β-acetoxy-6α-hydroxygermacra-4,11(13)-dien-12,8α-o lide, together with nine new highly oxygenated guaiadien-12,6α-olides of anthemolide, and cumambrin type were identified in the ...
A comparative study of the electrochemical properties of carbon nanotubes and carbon black
(Elsevier, 2009)
Two samples of commercial multi-walled carbon nanotubes (Sigma-Aldrich and Sun Nanotech) and a sample of carbon black (Vulcan XC-72R) were investigated in raw state and after the activation in nitric and sulfuric acid by ...
The electrocatalytic properties of the oxides of noble metals in the electrooxidation of methanol and formic acid
(Elsevier, 2001)
The electrooxidation of 0.25 M methanol as well as of 0.25 M formic acid was examined on oxides formed on the Au(111) electrode surface in 0.5 M H2SO4 and 0.5 M NaHCO3 at a sweep rate of 0.5 mV/s. In the case of methanol, ...
Plasma assisted degradation of phenol solutions
(Vacuum, 2008)
Solutions of 2-chlorophenol, 4-chlorophenol and 2,6-dichlorophenol in bidistilled and water from the river Danube were treated in plasma reactor. In this reactor, based on coaxial dielectric barrier discharge at atmospheric ...
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 ...
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 ...

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 ...
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 ...
