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 ...
New strain of 'Candidatus Phytoplasma ulmi' infecting Ulmus minor and U. laevis in Serbia
(Wiley, Hoboken, 2008)
Elm yellows (EY) phytoplasma (‘Candidatus Phytoplasma ulmi’) is the causal agent of a decline in American elms in North America, and in Eurasian elm species and hybrids in Europe (Lee et al., 2004). EY is known to infect ...
Comparative study of CeO2 nanopowders obtained by the hydrothermal method from various precursors
(Elsevier Sci Ltd, Oxford, 2015)
The effects of common precursors used in the synthesis of CeO2 nanopowders were investigated, and the structural and spectral properties of the resulting products were compared. Two cerium (III) salts, i.e., Ce(NO3)(3)center ...
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 ...
Hydrothermally assisted complex polymerization method for barium strontium titanate powder synthesis
(Springer, Dordrecht, 2013)
Barium strontium titanate was obtained by hydrothermal treatment of barium strontium titanate citric precursor solution, previously prepared by complex polymerization method. The thermally induced phase evolution was ...
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 ...
Effect of chemisorbed CO on MoOx-Pt/C electrode on the kinetics of hydrogen oxidation reaction
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The influence of poisoning of MoOx-Pt catalyst by CO on the kinetics of H-2 oxidation reaction (HOR) at MoOx-Pt electrode in 0 5 mol dm(-3) HClO4 saturated with H-2 containing 100 ppm CO was examined on rotating disc ...
Zinc-induced oxidative stress in Verbascum thapsus is caused by an accumulation of reactive oxygen species and quinhydrone in the cell wall
(Wiley, Hoboken, 2010)
Oxidative stress is one aspect of metal toxicity. Zinc, although unable to perform univalent oxido-reduction reactions, can induce the oxidative damage of cellular components and alter antioxidative systems. Verbascum ...
Liver, gills, and skin histopathology and heavy metal content of the Danube sterlet (acipenser ruthenus linnaeus, 1758)
(Setac Press, Pensacola, 2010)
The sterlet (Acipenser ruthenus L.) is a bottom-feeding fish species with a direct exposure to contaminants from water and sediments. Although heavy metal pollution is believed to be one of the main threats to the sterlet ...
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 ...
