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 ...
Influence of mechanical activation on the structure of ultrafine BaTiO3 powders
(Elsevier, 2009)
The influence of mechanical activation in a planetary ball mill on the change of the structure of BaTiO3 powders has been investigated. The particle size distribution of the nonactivated and activated samples was measured ...

Parameters optimization of acid activated bentonite clay from the coal mine 'Bogovina' / Optimizacija parametara kiselinske aktivacije bentonitnih glina iz RMU Bogovina
(Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije, Beograd, 2002)
The bentonite clays, depending on the type of activation, are used as an adsorption media, as the starting material for the catalyst's supports, in the water purification processing plants, in the storage processing of ...
Coordination behaviour and two-dimensional-network formation in poly[[μ-aqua-diaqua-(μ5-propane-1,3-diyldinitrilo-tetra-acetato) -dilithium(I)-cobalt(II)] dihydrate]: The first example of an M II-1,3-pdta complex with a monovalent metal counter-ion
(Acta Crystallographica Section C: Crystal Structure Communications, 2008)
The title compound, {[CoLi2(C11H14N2O8) (H2O)3]·2H2O}n , constitutes the first example of a salt of the [M II(1,3-pdta)]2- complex (1,3-pdta is propane-1,3-diyldinitrilo-tetra-acetate) with a monopositive cation as ...
Characterization of electrodeposited powders of the system Ni-Mo-O
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
The electrodeposition of the Ni-Mo-O alloy powders from ammonium chloride containing electrolytes for different Ni/Mo ions concentration ratios was investigated by the polarization measurements. The morphology, chemical ...
Study of gold-platinum and platinum-gold surface modification and its influence on hydrogen evolution and oxygen reduction / Površinska modifikacija platine zlatom i zlata platinom i njen uticaj na reakcije izdvajanja vodonika i redukcije kiseonika
(Serbian Chemical Society, 2005)
Surface modification of the electrodes was conducted from sulfuric acid solutions containing the corresponding metal-chloride complexes using cyclic voltammeter. Comparing the charges of the hydrogen underpotential deposition ...
Thermomagnetic behaviour and microstructure of a rapidly quenched Nd4.5Fe77B18.5 alloy
(Polish Academy of Sciences, 2008)
Changes in the phase composition and crystallite size, as well as changes in the magnetic behaviour of Nd4.5Fe77B18.5 alloy, caused by thermomagnetic measurements, was observed in regard of the optimal magnetic state of ...
Synthesis and characterization of new Pt(II) and Pd(II) complexes with 2-quinolinecarboxaldehyde selenosemicarbazone: Cytotoxic activity evaluation of Cd(II), Zn(II), Ni(II), Pt(II) and Pd(II) complexes with heteroaromatic selenosemicarbazones
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2009)
New complexes of Pt(II) and Pd(II) with 2-quinolinecarboxaldehyde selenosemicarbazone were synthesized and characterized by elemental analysis, NMR and IR spectroscopy and molar conductivity measurements. The assumed ...
Experimental investigation and thermodynamic calculation of the Cu-In-Sb phase diagram
(Calphad: Computer Coupling of Phase Diagrams and Thermochemistry, 2009)
The phase diagram of the Cu-In-Sb ternary system is of importance in predicting the interface reaction between In-based solder materials and the Cu substrate. The liquidus surface, invariant equilibria and four vertical ...
