Nanoscale topography of GC/Pt-C and GC/Pt-Ru-C electrodes studied by means of STM, AFM and XRD methods
(Materials Science Forum, 2006)
Electrodes, assigned as GC/Pt-C and GC/Pt-Ru-C, were formed by deposition of Pt-based catalysts (47.5 wt % Pt + high surface area carbon) and (54 wt. % Pt-Ru alloy + high surface area carbon) on glassy carbon (GC) discs. ...
Investigation of the ion defect states by photoacoustic spectroscopy
(25th International Conference on Microelectronics, MIEL 2006 - Proceedings, 2006)
The ion defect states in SiO2 film on Si substrata (SiO 2/Si) was investigated by photoacoustic (PA) spectroscopy. The amplitude and phase spectra were measured and analyzed in dependence on the energy of excitation optical ...
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 ...
Scanning probe-shaped nanohole arrays with extraordinary optical transmission as platform for enhanced surface plasmon-based biosensing
(Institute of Electrical and Electronics Engineers Inc., 2006)
We analyzed the use of subwaveleneth ordered nanohole patterns for detection of miniscule amounts of biological analytes. Owing to their surface plasmon resonance (SPR) operation, such structures show an extraordinarily, ...
Adsorbed mass fluctuations of a micro/nanoresonator surrounded by an arbitrary gas mixture
(Institute of Electrical and Electronics Engineers Inc., 2006)
Micro/nanoresonator mass and frequency fluctuations caused by sorption processes on a resonator surface are investigated. Arbitrary gas mixture is considered. assuming that particle arrivals at the surface are all poissonian ...
Silicon surface exfoliation under compression plasma flow action
(25th International Conference on Microelectronics, MIEL 2006 - Proceedings, 2006)
Silicon single crystal surfaces have been modified by supersonic compression plasma flows (CPF) action. Triangular and rhombic regular fracture features are obtained on the Si (111), while rectangular ones are produced on ...
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 ...
Analytical modeling of the triggering drain voltage at the onset of the kink effect for PD SOINMOS
(25th International Conference on Microelectronics, MIEL 2006 - Proceedings, 2006)
Here we give a new approach for calculating triggering drain bias at the onset of the kink effect utilizing electron drift properties in the channel. This approach directly relates electron mobility in the channel of the ...
Investigation of antimicrobial and antioxidant activity of seven Hypericum species / Ispitivanje antimikrobne i antioksidantne aktivnosti sedam Hypericum vrsta
(Pharmaceutical Association of Serbia, Belgrade, Serbia, 2006)
Influence of thermal treatment on polyphenolic compounds and antioxidant properties of Quercus robur kernels / Uticaj termičkog tretmana na polifenolne sastojke i antioksidantna svojstva semena lužnjaka, Quercus robur
(Pharmaceutical Association of Serbia, Belgrade, Serbia, 2006)
Polyphenolic compounds and antioxidant properties of dried MeOH extracts of native (QN) and thermally treated (QT) kernels of English Oak, Quercus robur were investigated. The content of total and simple polyphenols and ...
