Methanol oxidation at platinum electrodes in acid solution: Comparison between model and real catalysts / Oksidacija metanola na platinskim elektrodama u kiseloj sredini - poređenje model i realnih katalizatora
(Serbian Chemical Society, 2006)
Methanol oxidation in acid solution was studied at platinum single crystals, Pt(hkl), as the model catalyst, and at nanostructural platinum supported on high surface area carbon, Pt/C, as the real catalyst. The linear ...
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 ...
The chemical characteristics of soil which determine phosphorus partitioning in highly calcareous soils / Hemijske karakteristike visoko-krečnjačkih zemljišta koje određuju raspodelu fosfora
(Serbian Chemical Society, 2006)
Phosphorus fractions from three highly calcareous soils (average, 24.9 ± 4.8 %CO3 2-) from sampling sites with a Mediterranean climate were isolated by sequential extraction. In order to provide a more reliable basis for ...
The effect of perpendicularly oriented magnetic field on the formation of very disperse iron structures / Uticaj vertikalno orijentisanog magnetnog polja na formiranje veoma disperznih struktura gvožđa
(Serbian Chemical Society, 2006)
Iron deposits obtained without and with a perpendicularly oriented magnetic field were examined by scanning electron microscopy (SEM). It was found that the iron deposit obtained under a perpendicularly oriented magnetic ...
Influence of chloride ions on the open circuit potentials of chromium in deaerated sulfuric acid solutions / Uticaj hloridnih jona na potencijal otvorenog kola hroma u deaerisanim rastvorima sumporne kiseline
(Serbian Chemical Society, 2006)
Open circuit potential measurements and cyclic voltammetry of chromium in deaerated aqueous H2SO4 solution of pH 1 without and containing NaCl in the concentration range 0.5 - 4 M revealed that chromium exhibits two stable ...
The HPLC determination of the content of magnoflorine in Epimedium alpinum L. / HPLC одређивање садржаја магнофлорина у преволцу Epimedium alpinum L.
(Serbian Chemical Society, 2006)
The aporphine alkaloid magnoflorine, known as a constituent of Asian Epimedium species, was isolated for the first time from the wild growing European species, Epimedium alpinum L. Identification was done by comparison ...
The sorption and crystallographic characteristics of alumina activated in a reactor for pneumatic transport / Sorpcione i kristalografske karakteristike alumine dobijene u reaktoru za pneumatski transport čestica
(Serbian Chemical Society, 2006)
Active transition alumina powders were obtained by flash calcination of gibbsite in a reactor for pneumatic transport in the dilute, two-phase flow regime in the temperature interval from 883 to 943 K with a residence time ...
Phytochemical investigation of Anthemis cotula / Фитохемијско испитивање биљне врсте Anthemis cotula
(Serbian Chemical Society, 2006)
The investigation of roots of Anthemis cotula (Asteraceae) from east Serbia revealed, in addition to polyacetylenes previously isolated from the same species, three prenylated 4-hydroxyacetophenones, detected for the first ...
Factors affecting the microstructure of porous ceramics / Faktori koji utiču na mikrostrukturu porozne keramike
(Serbian Chemical Society, 2006)
In this study, porous ceramics were produced by using two methods: the polymeric sponge and foam method. A study of the effect of viscosity on the characteristics of the final product produced using the polymeric sponge ...
Physical modeling of representative particles of electrodeposited copper powders / Fizičko modelovanje reprezentativnih čestica elektrohemijski istaloženog bakarnog praha
(Serbian Chemical Society, 2006)
A method for the estimation of the size of the representative particle of a copper powder is given. Cross sections of representative particles of flowing and non-flowing powders estimated by this procedure are also presented.
