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 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 ...
Subwavelength hole arrays with nanoapertures fabricated by scanning probe nanolithography
(International Institute for the Science of Sintering, Beograd, 2006)
Owing to their surface plasmon-based operation, arrays of subwavelength holes show extraordinary electromagnetic transmission and intense field localizations of several orders of magnitude. Thus they were proposed as the ...
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 ...
Prediction of the particle circulation rate in a draft tube spouted bed suspension dryer / Predviđanje cirkulacije čestica u sušioniku za suspenzije sa modifikovanim fontanskim slojem
(Serbian Chemical Society, 2006)
A model for predicting the particle circulation rate in a draft tube spouted bed dryer with inert particles is proposed and verified. The calculation algorithm requires three input values: the gas velocity in the draft ...
Systemic NF-kappaB activation in blood cells of breast cancer patients
(Maney Publishing, 2006)
There is a well-established role for reactive oxygen and nitrogen species, chronic inflammation and immune response in the pathogenesis of breast cancer. Complex interactions between breast cancer cells and surrounding ...
Decorated Ru/Au(111) and Os/Au(111) surfaces: An in situ STM and electrochemistry study
(Russia : Maik Nauka-Interperiodica Publishing, 2006)
The structure and reactivity of bimetallic electrodes obtained by spontaneous deposition of Ru and Os on Au(111) single-crystal surfaces are studied. In situ electrochemical STM and cyclic voltammetry are used to characterize ...
A study of water influence on carbon monoxide adsorption and oxidation on nanocrystals of: γ-Fe2O3, Au/Fe2O 3 and MnxZn1-xFe2O4
(Materials Science Forum, 2006)
In this paper the adsorption and oxidation of CO on nanocrystalline Au/γ-Fe2O3, Au/α-Fe2O3, γ-Fe2O3 and a series of mixed ferrite with Mn xZn1-xFe2O4 composition are investigated. The catalysts were prepared by co-precipitation ...
Structural effects in electrocatalysis: Formic acid oxidation at model and real Pt catalysts
(Materials Science Forum, 2006)
Formic acid oxidation was studied at low-index Pt single crystals (model systems) as well as at the platinum catalyst supported on high area carbon (real catalyst) in HClO4. The Pt single crystals were characterized by ...
Morphology and phase composition of Ni-Co alloy powders electrodeposited from ammonium sulfate-boric acid electrolyte
(Materials Science Forum, 2006)
In this paper the morphology of Ni-Co powders electrodeposited from ammonium sulfate-boric acid containing electrolyte is investigated as a function of alloy powder composition. Composition of the electrolyte, i.e. the ...
