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 ...
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 ...
Morphology investigation of mechanically activated ZnO-SnO2 system
(Elsevier Sci Ltd, Oxford, 2008)
Powder mixtures of zinc oxide and tin oxide in the molar ratio, ZnO:SnO2 = 2: 1, were mechanically activated in a planetary ball mill in the time intervals of 0-160 min. The adsorption-desorption isotherms, specific surface ...
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 ...
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 ...
Structural characterization of mechanically milled ZnO: influence of zirconia milling media
(IOP Publishing Ltd, Bristol, 2008)
Zinc oxide nanoparticles were obtained by milling in a planetary ball mill with a zirconia milling assembly for up to 5 h in air. The samples were characterized by scanning electron microscopy, x-ray diffraction (XRD) and ...
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 ...
Peroxidase activity and phenolic compounds content in maize root and leaf apoplast, and their association with growth
(Elsevier Ireland Ltd, Clare, 2008)
Apoplastic fluid originated from maize (Zea mays L) leaf and root growing and non-growing regions were analyzed for peroxidase (POD) activities and phenols content. The samples were obtained by two different methods, as ...
Characterization of electrodeposited Cd-Co alloy coatings by anodic linear sweep voltammetry
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The electrodeposited Cd-Co alloys were characterized by the anodic linear sweep voltammetry (ALSV) technique in the solution of 1 M NaCl (pH 2). It is shown that Cd-Co alloys could be deposited with high current efficiency ...
Microstructure of LaNiO3 thin films obtained by the spin-on technique from citrate precursors
(Elsevier Sci Ltd, Oxford, 2008)
The morphology of perovskite LaNiO3 (LNO) thin films is a very important feature considering the fact that they could be used as an electrode material in ferroelectric devices. In this work, LNO films were prepared from ...
