Phenolics, lignin content and peroxidase activity in Picea omorika lines
(Biologia Plantarum, 2006)
We analyzed low molecular mass phenolics, lignin content and both soluble and cell wall bound peroxidase activity in the needles of three Picea omorika (Pancic) Purkyne lines grown in the generative seed orchard. The highest ...
Elektrohemijska oksidacija metanola i mravlje kiseline na model i realnim katalizatorima / Electrochemical oxidation of methanol and formic acid on model and real catalysts
(Универзитет у Београду, Технолошко-металуршки факултет, 2006)
Prema svim dosadašnjim saznanjima o okisdaciji metanola za odigravanje ove reakcije neophodo je prisustvo OH čestica na površini elektrode. One su neophodne i za oksidaciju mravlje kiseline po jednom od dva paralelna ...
Activity and stability of RuO2-coated titanium anodes prepared via the alkoxide route / Aktivnost i stabilnost titanskih anoda sa prevlakom od oksida rutenijuma dobijenom alkoksidnim postupkom
(Serbian Chemical Society, 2006)
Titanium anodes with an active RuO2 coating of two different thicknesses were prepared from the oxide suspended in ethanol ("ink" method), while the oxide itself was synthesized by the hydrolysis of ruthenium ethoxide in ...
Kinetic of corrosion reactions in acid and neutral solutions on electrochemically deposited Ni-W alloys / Kinetika korozionih reakcija u kiselim i neutralnim rastvorima na elektrohemijski taloženim legurama Ni-W
(Belgrade, Serbia : Engineering Society for Corrosion, 2006)
Ni-W alloys were electrochemically deposited from an ammonia-citrate electrolyte on rotating disc electrode with a gold disc, by direct and pulsating current. The corrosion potential and kinetics of cathodic and anodic ...
The formation of natural gas prices charged to very large industrial users in Serbia according to standards of the European union / Formiranje cena prirodnog gasa za velike industrijske potrošače u Srbiji prema standardima evropske unije
(Institut za istraživanja i projektovanja u privredi, Beograd, 2006)
Natural gas is a primary energy resource with the indicated highest annual growth of global demand and consumption in all recent forecasts. The chemical industry is a leading non-seasonal consumer of natural gas, mainly ...
Tetraoxane antimalarials and their reaction with Fe(II)
(American Chemical Society (ACS), 2006)
Mixed tetraoxanes 5a and 13 synthesized from cholic acid and 4-oxocyclohexanecarboxylic acid were as active as artemisinin against chloroquine-susceptible, chloroquine-resistant, and multidrug-resistant Plasmodium falciparum ...
Synthesis of amorphous boron carbide by single and multiple charged boron ions bombardment of fullerene thin films / Sinteza amorfnog bor karbida bombardovanjem tankih slojeva fulerena jonima bora
(Tehnika - Novi materijali, 2006)
In this paper, results of structural modification of fullerene thin films by single and multiple charged boron ions (B+, B3+) are presented. The applied ion energies were in the range of 15 to 45 keV. The characterization ...
Nanofabrication of planar split ring resonators for negative refractive index metamaterials in the infrared range / Nanofabrikacija planarnih split ring rezonatora za metamaterijale sa negativnim indeksom prelamanja u infracrvenom opsegu
(Serbian Chemical Society, 2006)
Experimental nanofabrication of planar structures for one-dimensional metamaterials designed to achieve a negative effective refractive index in the mid-infrared range (5-10 micrometers) was performed. Double split ring ...
Pulse and direct current plating of Ni-W alloys from ammonia-citrate electrolyte
(Elsevier, 2006)
The effect of the potential of deposition and electrode rotation rate on current efficiency and partial current density of nickel deposition from ammonia-citrate electrolyte with and without tungstate ions was investigated. ...
