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 ...
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 ...
Investigation of the effects of Ar plasma etching in Si surface by photoacoustic method
(EDP Sciences, 2005)
The effects of Ar plasma treatment on the Si surface were investigated by photoacoustic spectroscopy and atomic force microscopy. We studied the surface structure as a function of plasma experimental parameters to correlate ...
Photoacoustic investigations of thermal and electronic properties of single crystal Ge doped with Cr
(EDP Sciences, Les Ulis Cedex A, 2005)
A high purity single crystal Ge with a (1 1 1) orientation was doped with Cr. A thin film of Cr was evaporated and then diffused into Ge substrate. The photoacoustic PA amplitude and phase spectra were measured and numerically ...
Synthesis of mesoporous nanocrystalline titania powders by nonhydrolitic sol-gel method
(Academic Press Ltd- Elsevier Science Ltd, London, 2009)
Mesoporous titania with well-crystallized anatase phase was synthesized by nonhydrolytic sol-gel process combined with solvothermal treatment. Titanium-isopropoxide, titanium-tetrachloride, and carbon-tetrachloride were ...
On the relationship between effective electron mobility and kink effect for short-channel PD SOINMOS devices
(World Scientific Publ Co Pte Ltd, Singapore, 2008)
Here, a new approach for calculating the triggering drain bias at the onset of the kink effect, kink voltage, V-kink, for PD SOI NMOS devices utilizing electron drift properties in the channel is given. This approach ...
Electrochemically deposited Ni+WC composite coatings obtained under constant and pulsating current regimes
(Netherlands : Kluwer Academic Publishers, 2004)
A series of Ni þ WC composite coatings were obtained by electrodeposition on a rotating disc electrode (RDE)
from a commercially available Watts bath containing additives for brightness and smoothing and insoluble ...
Formic acid oxidation on Pt/Ru nanoparticles: Temperature effects
(Trans Tech Publications Ltd, Durnten-Zurich, 2005)
The formic acid oxidation on Pt/Ru nanoparticles in acid solution over the temperature range 298-333 K has been studied by thin-film rotating disk method (RDE). Transmission electron microscopy in combination with scanning ...
Coordination behaviour and two-dimensional-network formation in poly[[μ-aqua-diaqua-(μ5-propane-1,3-diyldinitrilo-tetra-acetato) -dilithium(I)-cobalt(II)] dihydrate]: The first example of an M II-1,3-pdta complex with a monovalent metal counter-ion
(Acta Crystallographica Section C: Crystal Structure Communications, 2008)
The title compound, {[CoLi2(C11H14N2O8) (H2O)3]·2H2O}n , constitutes the first example of a salt of the [M II(1,3-pdta)]2- complex (1,3-pdta is propane-1,3-diyldinitrilo-tetra-acetate) with a monopositive cation as ...
The retention behaviour of some cholic acid derivatives on different adsorbents
(Research Inst Medicinal Plants, Budakalasz, 2002)
The thin-layer chromatographic behavior of cholic acid and fourteen of its synthetic derivatives has been studied in six reversed-phase and three normal-phase systems. Four significantly different adsorbents were used - ...
