Synthesis, characterization and electrocatalytical behavior of Nb-TiO2/Pt nanocatalyst for oxygen reduction reaction
(Elsevier Science Bv, Amsterdam, 2010)
In order to point out the effect of the support to the catalyst for oxygen reduction reaction nano-crystalline Nb-doped TiO2 was synthesized through a modified sol-gel route procedure. The specific surface area of the ...
Surrogate data test for nonlinearity of the rat cerebellar electrocorticogram in the model of brain injury
(Elsevier Science Bv, Amsterdam, 2010)
The surrogate data test for nonlinearity has been used in order to establish the existence of nonlinear dynamics and justify the use of nonlinear tools in time series analysis. We applied Higuchi fractal dimension and ...
Soil Properties and Trace Elements Contents Following 40 Years of Phosphate Fertilization
(Wiley, Hoboken, 2010)
Long-term application of P fertilizers may eventually result: in excess and/or toxic accumulations of trace elements and microelements in soil. The effect of monoammonium-phosphate (MAP) on basic soil properties (pH, CEC, ...
Parallel analysis of axial pressing, casting and PIM as routes for production of alnico8
(European Powder Metallurgy Association (EPMA), 2010)
Samples of Alnico8 were prepared from the same starting powder by pressing, casting and powder injection moulding (PIM), respectively, and characterized by SEM and thermal analysis-DTA/TGA. Optimization of the sintering ...
Bioavailability and catalytic properties of copper and iron for Fenton chemistry in human cerebrospinal fluid
(Maney Publishing, Leeds, 2010)
A breakdown in homeostasis of redox-active metals represents an important factor for neurodegeneration. We have used EPR spectroscopy and BMPO spin-trap to investigate the catalytic properties and ligand modulation of redox ...
Structure study of nanosized La- and Sb-doped BaTiO3
(Elsevier Science Sa, Lausanne, 2010)
Lanthanum and antimony doped barium titanate powders were prepared by polymeric precursors method through Pechini process. Obtained powder was pressed into pellet and sintering was performed at 1300 degrees C for 8 h. The ...
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 ...
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 ...
Elektronska paramagnetna rezonanca - moćno oruđe medicinske biohemije u otkrivanju mehanizama oboljenja i mogućih tretmana / Electron paramagnetic resonance: A powerful tool of medical biochemistry in discovering mechanisms of disease and treatment prospects
(Društvo medicinskih biohemičara Srbije, Beograd i Versita, 2010)
EPR, free radicals, oxidative status, oxidative stress, antioxidants Kratak sadržaj: U patofiziološkim uslovima povezanim sa oksidativnim stresom, primenjivanje određenih antioksidativnih materija može biti od koristi za ...
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 ...
