PZT ceramics obtained from mechanochemically synthesized powders
(Kluwer Academic Publ, Dordrecht, 2003)
PZT ceramics were obtained from the mechanochemically synthesized powders. Milling and sintering conditions were optimized based on results of density measurements, as well as on microstructural and electrical characterization. ...

(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2002)
Electrodeposition of Ni-Mo alloy coatings and their characterization as cathodes for hydrogen evolution in sodium hydroxide solution
(Elsevier, 2008)
The hydrogen evolution reaction on the electrodeposited Ni-Mo alloy coatings, as well as their electrochemical properties in the NaOH solutions, have been investigated by the polarization measurements, cyclic voltammetry ...
Preparation and characterization of iron(III) phosphate-oxalate using 1,2-diaminopropane as the structure-directing agent
(Elsevier, Amsterdam, 2002)
Iron(III) phosphate-oxalate (FePO-DAP) crystallizes from a clear solution containing 1,2-diaminopropane (DAP) and oxalic acid at 120 degreesC under hydrothermal conditions. Doubly protonated DAP is present inside a large ...
Sorption properties of TEMPO-oxidized natural and man-made cellulose fibers
(Elsevier Sci Ltd, Oxford, 2009)
Cotton and lyocell fibers were oxidized with sodium hypochlorite and catalytic amount of sodium bromide and 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO), under various conditions. Water-insoluble fractions, collected ...
The crystallisation of calcium phosphate glass containing vanadium oxide
(University of Chemistry and Technology, Prague, 2007)
The crystallisation behaviour of calcium phosphate glass containing vanadium oxide was studied. Glass with a molar ratio of [CaO]/[P2O5] = 1.13 and a V2O5 content of 8 mol.% was prepared for the experiments. The crystallisation ...
Synthesis and structure determination of a chain-like aluminophosphate obtained with 1,2-diaminopropane as the structure-directing agent
(Pergamon-Elsevier Science Ltd, Oxford, 2003)
Colorless plate-like crystals (AIPO-1,2DAP) crystallize from a clear 'AlPO4-1,2-diaminopropane' reaction system. The results of elemental, thermal and FTIR analyses give the following chemical formula: (NH4+)(1,2-H(2)DAP ...
New inorganic-organic hybrid: Synthesis and structural characterization of an alumino(oxalato)phosphate
(Amer Chemical Soc, Washington, 2003)
A new 3-D alumino(oxalato)phosphate, [H3NCH(CH3)CH2NH3](2)[Al4P6O20(OH)(4)(C2O4)(H2O)], consists of aluminophosphate layers which are pillared by oxalate anions. It contains a hybrid 12-membered channel where guest species, ...
Thermal deamination kinetics of the nickel-containing chabazite-like aluminophosphate, Ni(NH2-CH2-CH2-NH2)(2)(AlPO4)(6)(OH)(2), deposition of nanocrystalline NiO particles
(Elsevier Science Sa, Lausanne, 2009)
Thermogravimetrical analysis has been used to study the kinetics of thermal deamination of bis(ethylenediamine) nickel(II)-containing aluminophosphate (Ni-CHA) which is a precursor of nickel(II)-containing chabazite-like ...
Spectrophotometric study of the anodic corrosion of Ti/RuO2 electrode in acid sulfate solution
(Elsevier Ltd., 2004)
Electrochemical properties of RuO2-based electrode, particularly the oxygen evolution and anodic dissolution of RuO2 have been investigated in 0.5 mol dm-3 H2SO4 solution by means of polarization measurements and product ...
