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) - ...
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 ...
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 ...
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 ...
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 ...
Segmented thermistors printed by NTC nanometric paste and applied in volume air-flow sensors
(Materials Science Forum, 2006)
An investigation path starting from (Mn,Ni,Co,Fe)3O4 nanometric powder preparation, NTC thick-film characterization, realization and optimization of new planar thermistor geometries to custom design thermistors and their ...
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
