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 ...
Morphology and capacitive properties of [RuOxH y/low-surface area carbon black] composite materials prepared by sol-gel procedure
(Materials Science Forum, 2005)
The morphology and the capacitive properties of carbon supported hydrous ruthenium oxide (RuOxHy/C), prepared by impregnation of low-surface area carbon black Vulcan® XC-72 R with solid phase of RuO xHy sol, were investigated ...
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 ...
Mass transfer and fluid flow visualization in packed and fluidized beds by the adsorption method
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Mass transfer coefficient (j D ) between fluid and column wall in liquid packed and fluidized beds of spherical inert particle has been studied experimentally using adsorption method. Experiments were conducted in column ...
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) - ...
The state of nickel in the silver modified NiMg/SiO2 vegetable oil hydrogenation catalysts
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Two series of silver modified Ni-Mg materials were synthesized by precipitation-deposition on SiO2 support derived from two silica sources: diatomite activated at 800°C (Series a; Mg/Ni = 0.1 and SiO 2/Ni = 1.07) and ...
Investigation of the interface states in the SiO2– Si system by photoacoustic method
(EDP Sciences, 2005)
The interface states in SiO2 - Si system was investigated by photoacoustic (PA) spectroscopy. The amplitude and phase spectra were measured and analyzed in dependence on the wavelength of excitation optical beam. In the ...
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 ...
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 ...
