Adsorption and corrosion inhibitive properties of some organic molecules on iron electrode in sulfuric acid
(Elsevier, 2002)
Adsorption and corrosion inhibitive properties of three different organic molecules: 2-naphthalenesulfonic acid, 2,7-naphthalenedisulfonic acid and 2-naphthol-3,6-disulfonic acid are investigated on Armco-iron electrode ...
LaMO3 (M = Mg, Ti, Fe) perovskite type oxides: Preparation, characterization and catalytic properties in methane deep oxidation
(Elsevier, 2008)
Two new series of perovskite-type oxides LaMO3 (M = Mg, Ti, Fe) with different ratio Mg/Fe (MF) and Ti/Fe (TF) in the B cation site were prepared by annealing the precursor, obtained by the mechanochemical activation (MCA) ...
Catalytic combustion of methane over Pd containing perovskite type oxides
(Elsevier, 2005)
The mixed perovskite type oxides with nominal formula LaTi0.5Mg0.5-xPdxO3, (0 LT = x LT = 0.10) were prepared by anneling the ethanol solution of precursor in nitrogen flow at 1200 degrees C. X-ray powder diffraction ...
Pyrolysis and Pt(IV)- and Ru(III)-ion catalyzed pyrolysis of asphaltenes in organic geochemical investigation of a biodegraded crude oil (Gaj, Serbia)
(Elsevier Sci Ltd, Oxford, 2009)
This paper is aimed at investigating the origin and geological history of the biodegraded Gaj (Serbia) crude oil, based on comparison of biomarkers, particularly alkylaromatics, in crude oil maltene fraction, with those ...
Differentiation of the contribution of local resuspension from that of regional and remote sources on trace elements content in the atmospheric aerosol in the Mediterranean area
(Oxford : Pergamon-Elsevier Science Ltd, 2005)
For the determination of effects of contaminated crude soil on the content of trace elements in the atmospheric aerosol, trace elements in crude soil samples from within the area of influence of local resuspension were ...
Ring-closing metathesis/fragmentation route to geometrically defined medium-ring cycloalkenes: Total synthesis of (+/-)-periplanone C
(American Chemical Society (ACS), 2004)
The combination of alkene metathesis and beta-fragmentation offers an efficient entry into (Z)-configured medium-ring cycloalkenes. The versatility of this method is demonstrated by the total synthesis of Periplanone C, a ...
Influence of carrier diffusion on the response of a resonant-cavity enhanced detector
(IEEE Journal of Quantum Electronics, 2002)
We have investigated the effects of carrier diffusion on the impulse response of a resonant-cavity enhanced photodetector using our analytic expression for a short-circuit current. Our theoretical results indicate that ...
The effect of diffusion on the impulse response of RCE detector
(IEEE Photonics Technology Letters, 2001)
We present a theory which demonstrates how the diffusion of photogenerated carriers affects the impulse response of a resonant-cavity enhanced photodetector (RCE). Analytic expressions for carrier densities and short-circuit ...
Influence of mechanical activation on the structure of ultrafine BaTiO3 powders
(Elsevier, 2009)
The influence of mechanical activation in a planetary ball mill on the change of the structure of BaTiO3 powders has been investigated. The particle size distribution of the nonactivated and activated samples was measured ...
Wall-to-bed heat transfer in vertical hydraulic transport and in particulate fluidized beds
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
Wall-to-bed heat transfer in hydraulic transport and in particulate fluidized beds of spherical particles was studied. Experiments were performed by spherical glass particles of 0.80-2.98 mm in diameter with water in a ...
