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 ...
Chemical and radiochemical characterization of depleted uranium in contaminated soils
(Maik Nauka/Interperiodica/Springer, New York, 2007)
The main results of chemical and radiochemical characterization and fractionation of depleted uranium in soils contaminated during the Balkan conflict in 1999 are presented in the paper. Alpha-spectrometric analysis of ...
N-type silicon electron mobility and its relationship to the kink effect for nano-scaled SOI NMOS devices
(Materials Science Forum, 2007)
Electron mobility for the silicon-based devices is one of the most important parameters, which determine the behavior of components. Mobility depends on silicon purity, doping level, presence of lattice defects and electric ...
Microstructural properties of PZT thin films deposited on LaNIQ 3-coated substrates
(Materials Science Forum, 2007)
The modified polymeric precursor method (Pechini method) was successfully used for the preparation of epitaxial and polycrystalline ferroelectric Pb(Zr0.52Ti0.48)O3 (PZT) thin films. Films were deposited on LaNiO3 (LNO) - ...
Synthesis, characterization and biological activity evaluation of novel Pd(II) and Pt(II) complexes with heterocyclic hydrazone ligands
(Materials Science Forum, 2007)
New complexes of Pt(II) with condensation derivatives of ethyl hydrazinoacetate and either 2-acetylpyridine or 2-quinolinecarboxaldehyde, and of Pd(II) with the condensation derivative of ethyl hydrazinoacetate and ...
Efficiency of commercial enzymatic preparations in grain hydrolysis for preparation of substrates for beer fermentation
(Blackwell Publishing, 2007)
The chemical composition of malt is of crucial importance for wort quality and together with conditions of fermentation process, they determine beer quality. Commercial enzymes preparations compensate enzymes naturally ...
Electrochemical behavior of 5-substituted 2-alkylidene-4-oxothiazolidine derivatives studied by cyclic voltammetry
(Maik Nauka/Interperiodica/Springer, New York, 2007)
This study demonstrates the electrochemical activity of selected 2-alkylidene-4-oxothiazolidine compounds containing different substituents at the C5-position on the Pt-electrode in 0.1 M TBAHFP + MeCN in the potential ...
Phase composition and magnetic properties of multiphase melt-spun Nd 4.3Fe76.2B19.5alloy
(Materials Science Forum, 2007)
Phase transformations and magnetic properties of multiphase Nd 4.5Fe76.2B19.5 alloy were investigated in the temperature range of heat treatment 600-700°C. The influence of different heat treatment regimes was observed by ...
Preparation of ZrO2 and Al2O3 thin-films on stainless steel by spray pyrolysis
(Research Trends in Contemporary Materials Science, 2007)
We have investigated the deposition of ZrO2 and Al2O3 films on a stainless steel (SS) substrate by spray pyrolysis method. The ZrO2 films were deposited from aqueous solution of zirconium dinitrate oxide. For Al2O3 films, ...
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 ...
