Catalytic incineration of ethylene oxide in the packed bed reactor
(Elsevier, 2006)
Investigations of catalytic incineration of ethylene oxide (ETO) over Pt/Al2O3 catalyst have been conducted on laboratory and pilot scale level. The measurements of the reaction rate conducted under gradientless conditions ...
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 ...
A QSAR study of acute toxicity of N-substituted fluoroacetamides to rats
(Oxford : Pergamon-Elsevier Science Ltd, 2006)
Acute toxicity in vivo toward rats, of nineteen N-alkyl and N-cycloalkyl fluorocetamides [F-CH2-C(O)-NH-R] was correlated with their structure-dependent properties. Used descriptors are: molecular weights (M-w) and heat ...
Structural effects in electrocatalysis: Formic acid oxidation at model and real Pt catalysts
(Materials Science Forum, 2006)
Formic acid oxidation was studied at low-index Pt single crystals (model systems) as well as at the platinum catalyst supported on high area carbon (real catalyst) in HClO4. The Pt single crystals were characterized by ...
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 ...
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 ...
Adsorbed mass fluctuations of a micro/nanoresonator surrounded by an arbitrary gas mixture
(Institute of Electrical and Electronics Engineers Inc., 2006)
Micro/nanoresonator mass and frequency fluctuations caused by sorption processes on a resonator surface are investigated. Arbitrary gas mixture is considered. assuming that particle arrivals at the surface are all poissonian ...
Silicon surface exfoliation under compression plasma flow action
(25th International Conference on Microelectronics, MIEL 2006 - Proceedings, 2006)
Silicon single crystal surfaces have been modified by supersonic compression plasma flows (CPF) action. Triangular and rhombic regular fracture features are obtained on the Si (111), while rectangular ones are produced on ...
