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 ...
Removal of organically bound sulfur from oil shale by iron(III)-ion generated-regenerated from pyrite by the action of Acidithiobacillus ferrooxidans
(Trans Tech Publications Ltd, Durnten-Zurich, 2007)
Oil shales are one of the alternative sources of hydrocarbon fuels ("synthetic petroleum"), characterized by the increased sulfur and nitrogen content which represent even greater ecological problem in use, compared to ...
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 ...
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 ...
Characterization and catalytic activity of poly(4-vinylpyridine-co- divinylbenzene)-Co2+ complex
(Materials Science Forum, 2005)
Poly(4-vinylpyridine-co-divinylbenzene)-Co2+ was characterized using infrared spectroscopy (IR), thermogravimetric analysis (TG-DTA), N 2-physisorption and polarography. Thermal analysis suggests sufficient thermal stability ...
A wireless system for liquid level measurement
(8th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Servi, 2007)
A wireless system for liquid level measurement is presented. It is developed in order to meet stringent power consumption requirements, but without sacrificing the accuracy of the built-in pressure sensor. The communication ...
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 ...
Boron redistribution during SOI wafers thermal oxidation
(Institute of Electrical and Electronics Engineers Inc., 2006)
We fabricated Silicon-On-Insulator (Sol) pressure sensors intended for operation in a wide temperature range. After the thermal oxidation process, the measured sheet resistance of the silicon active layer was higher than ...
Multidisciplinary research of old cultures in the work of Harald Haarmann
(Београд : Централни институт за конзервацију и Друштво за етичност и вредновање у култури и науци, 2020)
Early civilizations, cultural continuity, stylistic characterizations and structural elements of language, as well as ecological culture, are basic themes in the multidisciplinary work of the German researcher Harald ...
Methodology and design in production of ortodox golden crosses
(Београд : Друштво за етичност и вредновање у култури и науци и Централни институт за конзервацију, 2020)
In Christianity the cross is principaly simbol of beleiving, representing the crusification of Christ and his pain for all. The methodology of making and design of cross primarly depends from the purpose: is the cross used ...
