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 ...

Synthesis, characterization and in vitro cytotoxicity studies of platinum(IV) complexes with thiouracil ligands
(Elsevier, 2010)
Reactions of [PtMe3(bpy)(Me2CO)][BF4] (2) with the thionucleobases 2-thiouracil (s2Ura), 4-thiouracil (s 4Ura) and 2,4-dithiouracil (s2s4Ura) resulted in the formation of complexes of the type [PtMe3 (bPy)(L-κS)] [BF4] (L= ...
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 ...
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, ...
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 ...
