The effect of the electrode surface roughness at low level of coarseness on the polarization characteristics of electrochemical processes
(Oxford : Pergamon-Elsevier Science Ltd, 2010)
In this study, it is considered: (a) the effect of the exchange current density to the limiting diffusion current density ratio (J(0)/J(L)) at low level of surface coarseness on the polarization characteristics of the ...
Immobilization of Cell Wall Invertase Modified with Glutaraldehyde for Continuous Production of Invert Sugar
(American Chemical Society (ACS), 2010)
Yeast cell wall invertase (CWI) was modified with dimethyl suberimidate, glutaraldehyde, formaldehyde, and sodium periodate. Retained activity after modification was 45% for CWI modified with formaldehyde, 77% for CWI ...
Reduction of Oxygen at a NaX-Ag Composite Electrode and Its Application to the Determination of Oxygen in Aqueous Media
(Maik Nauka/Interperiodica/Springer, New York, 2010)
A composite mixture Ag-NaX zeolite (silver concentration 16.7% w/w) is synthesized usingimpregnation and thermal decomposition. For silver impregnation, a solution of an Ag acetylacetonate complex in acetone was used. ...
Electrodeposition of Fe Powder from Citrate Containing Electrolytes
(Esg, Belgrade, 2010)
Polarization characteristics of the electrodeposition processes of Fe powders from different citrate electrolytes and the morphology of the obtained powders were investigated. The effect of complexing agents on the cathodic ...
The electrochemical properties of carbon nanotubes and carbon XC-72R and their application as Pt supports / Elektrohemijske karakteristike ugljeničnih nanocevi i ugljenika XC-72R i njihova primena u sintezi Pt katalizatora
(Serbian Chemical Society, 2010)
The results of an investigation of two samples of commercial multi-walled carbon nanotubes and a sample of carbon black, in the raw and activated state, were presented in the lecture. The activation of the carbon materials ...

STACKING INTERACTIONS BETWEEN PYRIDINE FRAGMENTS IN CRYSTAL STRUCTURES OF TERPYRIDYL COMPLEXES
(Univ Babes-Bolyai, Cluj-Napoca, 2010)
In the crystal structures of terpyridyl complexes from the Cambridge Structural Database (CSD) stacking interaction between the pyridine fragments were studied. Square-planar complexes where the distance between the centers ...
Fluctuations of the adsorbed mass and the resonant frequency of vibrating MEMS/NEMS structures due to multilayer adsorption
(Elsevier, 2010)
This paper presents the analysis of fluctuations of both the number and the mass of particles adsorbed on the surface of MEMS/NEMS structures, as well as the fluctuations of the micro/nanostructure resonant frequency, in ...
Electrochemical behavior of silver-impregnated Al-pillared smectite in alkaline solution
(Springer, New York, 2010)
In order to enhance silver effectiveness for oxygen reduction reaction, pillared clay was used as a support for silver nanodispersion. Silver particles incorporation into pillared clay pores was attempted by impregnation/thermal ...
