Effect of chemisorbed carbon monoxide on Pt/C electrode on the mechanism of the hydrogen oxidation reaction
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The influence of poisoning of Pt catalyst by CO on the kinetics and mechanism of H-2 oxidation reaction (HOR) at Pt/C electrode in 0.5 mol dm(-3) HClO4, saturated with H-2 containing 100 ppm CO, was examined with rotating ...
Improved total conductivity of nanometric samaria-doped ceria powders sintered with molten LiNO3 additive
(Elsevier, Amsterdam, 2009)
Nanometric 20% molar Sm-doped ceria (SDC20) powders were synthesized by co-precipitation in the presence of N, N, N', N' tetramethylethylendiamine (TMEDA). SDC20 powders were sintered using lithium nitrate salt in various ...
Incidence and Distribution of Iris yellow spot virus on Onion in Serbia
(Amer Phytopathological Soc, St Paul, 2009)
In a survey to determine the presence and distribution of It-is yellows, spot virus (IYSV) in greenhouse ornamentals and onion field crops in 14 districts of Serbia as well as on imported ornamental plants, 1,574 samples ...
Synthesis and characterization of ceria based nanometric powders
(Elsevier Science Bv, Amsterdam, 2009)
Nanopowdered solid solution Ce(1-x)Fe(x)O(2-delta) samples (0 lt = x lt = 0.1) were synthesized by a self-propagating room temperature synthesis (SPRT). XRD and Raman spectroscopy at room temperature were used to study ...
Electrophoretic deposition of dense BaCe0.9Y0.1O3-x electrolyte thick-films on Ni-based anodes for intermediate temperature solid oxide fuel cells
(Elsevier, Amsterdam, 2009)
Proton conducting BaCe0.9Y0.1O3-x (BCY10) thick films are deposited on cermet anodes made of nickel-yttrium doped barium cerate using electrophoretic deposition (EPD) technique. BCY10 powders are prepared by the citrate-nitrate ...
Far infrared study of impurity local modes in Pr doped PbTe
(Elsevier Science Sa, Lausanne, 2009)
Single crystal samples of lead telluride doped with Pr were produced using the Bridgman method. Far infrared spectra of the samples doped with 0.15 at%, 0.25 at% and 0.6 at% Pr are presented. The experimental data were ...
A wet-chemical route for the preparation of Ni-BaCe0.9Y0.1O3-delta cermet anodes for IT-SOFCs
(Elsevier, Amsterdam, 2009)
Nano-sized BaCe0.9Y0.1O3 - delta (BCY10) protonic conductor powders were used to prepare Ni-BCY10 cermets for anode-supported intermediate temperature solid oxide fuel cells. A new wet-chemical route was developed starting ...
Morphology and composition of the Fe-Ni powders electrodeposited from citrate containing electrolytes
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The electrodeposition of the Fe-Ni powders from citrate containing electrolytes for different Ni/Fe ions concentration ratios, using Fe(Ill) and Fe(II) salts at pH 4.5 and pH 4.0 respectively was investigated by the ...
Chlorophyll bleaching by UV-irradiation in vitro and in situ: Absorption and fluorescence studies
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
Chlorophyll bleaching by UV-irradiation has been studied by absorbance and fluorescence spectroscopy in extracts containing mixtures of photosynthetic pigments, in acetone and n-hexane solutions, and in aqueous thylakoid ...
Kinetic study of the hydrogen oxidation reaction on sub-stoichiometric titanium oxide-supported platinum electrocatalyst in acid solution
(Elsevier Science Bv, Amsterdam, 2009)
The kinetics and mechanism of the hydrogen oxidation reaction were studied in 0.5 mol dm(-3) HClO4 solution on an electrode based on titanium oxide with Magneli phase structure-supported platinum electrocatalyst applied ...
