Microstructural and electrical changes in nickel manganite powder induced by mechanical activation
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Nickel manganite powder synthesized by calcination of a stoichiometric mixture of manganese and nickel oxide was additionally mechanically activated in a high energy planetary ball mill for 5-60 min in order to obtain a ...
Defect induced variation in vibrational and optoelectronic properties of nanocrystalline ZnO powders
(Amer Inst Physics, Melville, 2011)
Structural disorder of ZnO nanopowders with mean crystallite size down to 15 nm, produced by mechanical activation in high energy mills, has been analyzed by x-ray diffraction and Raman spectroscopy. The influence of such ...
Determination of differential heavy metal and trace element accumulation in liver, gills, intestine and muscle of sterlet (Acipenser ruthenus) from the Danube River in Serbia by ICP-OES
(Elsevier Science Bv, Amsterdam, 2011)
The accumulation of heavy metals in fish has been extensively studied and well documented. However, the research has been mainly focused on the muscle tissue, while the distribution patterns among other tissues, such as ...
Independent complexity patterns in single neuron activity induced by static magnetic field
(Elsevier Ireland Ltd, Clare, 2011)
We applied a combination of fractal analysis and Independent Component Analysis (ICA) method to detect the sources of fractal complexity in snail Br neuron activity induced by static magnetic field of 2.7 mT. The fractal ...
Structural characterization of self-assembled ZnO nanoparticles obtained by the sol-gel method from Zn(CH3COO)(2)center dot 2H(2)O
(IOP Publishing Ltd, Bristol, 2011)
Zinc oxide nanopowders were synthesized by the sol-gel method from an ethanol solution of zinc acetate dihydrate. Detailed structural and microstructural investigations were carried out using x-ray diffraction, Raman ...
Anode Supported Protonic Solid Oxide Fuel Cells Fabricated Using Electrophoretic Deposition
(Wiley-V C H Verlag Gmbh, Weinheim, 2011)
Intermediate temperature solid oxide fuel cells (IT-SOFCs) were fabricated depositing proton conducting BaCe0.9Y0.1O3-x (BCY10) thick films on cermet substrates made of nickel oxide-yttrium doped barium cerate (NiO-BCY10) ...
Structural and magnetic properties of nanocrystalline bismuth manganite obtained by mechanochemical synthesis
(Springer, Dordrecht, 2011)
We have studied the formation of BiMnO3 (BMO) nanocrystalline perovskite powder produced by high-energy milling of the constituent oxides. The crystal structure and the amount of crystalline and amorphous phases in the ...
Antimony doping effect on barium titanate structure and electrical properties
(Elsevier Sci Ltd, Oxford, 2011)
Nanopowders of pure and antimony doped barium titanate (BaTiO3-BT) were synthesized by polymeric precursors method based on Pechini process. Obtained powders were pressed and sintered at 1300 degrees C for 8 h. XRD analysis ...
Determination of the size of quantum dots by fluorescence spectroscopy
(Royal Soc Chemistry, Cambridge, 2011)
There has been a lack of quick, simple and reliable methods for determination of nanoparticle size. An investigation of the size of hydrophobic (CdSe) and hydrophilic (CdSe/ZnS) quantum dots was performed by using the ...
Optimization of electrolytic process of formation of open and porous copper electrodes by the pulsating current (PC) regime
(Elsevier Science Sa, Lausanne, 2011)
Optimization of process of formation of open and porous copper electrodes, denoted as the honeycomb-like ones, by the regime of pulsating current (PC) is considered. The square-waves PC were consisted of the same amplitude ...
