The current efficiency during the cathodic period of reversing current in copper powder deposition and the overall current efficiency / Iskorišćenje struje za vreme katodnog perioda reversne struje pri taloženju bakarnog praha i ukupno iskorišćenje struje
(Serbian Chemical Society, 2003)
The current efficiency during the cathodic period of reversing current in copper powder deposition was determined by measuring the quantity of hydrogen evolved. The diagrams from which the instantaneous and average current ...
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. ...
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, ...
The effect of segment length on some properties of thermoplastic poly(ester-siloxane)s
(John Wiley and Sons Ltd, 2003)
A series of novel thermoplastic elastomers, based on poly(dimethylsiloxane) (PDMS) as the soft segment and poly(butylene terephthalate) (PBT) as the hard segment, were synthesized by catalyzed two-step, melt transesterification ...
Adsorption of oxygen containing species and their effect on oxygen reduction on Pt3Co electrode
(Elsevier Science Sa, Lausanne, 2003)
A rotating Pt3Co, thermally prepared alloy disc is used to study electrochemical oxygen reduction in alkaline solutions of different pH. In all solutions two Tafel regions are found: at low current densities partial ...
Epoxy coatings electrodeposited on steel electrochemically modified by Zn-Co alloys / Epoksidne kataforetske prevlake na čeliku modifikovanom Zn-Co legurama
(Engineering Society for Corrosion, Belgrade, Serbia, 2003)
The corrosion behavior of epoxy coatings electrodeposited on steel and steel modified by Zn-Co alloys deposited from chloride and sulphate baths were investigated during exposure to 3 % NaCl. The electrochemical impedance ...
Characterization of alumina films electrodeposited on steel from water suspensions
(InterCeram: International Ceramic Review, 2003)
Alumina films were electrodeposited on steel from water suspensions using the constant voltage method. The morphology of deposited films was investigated using optical microscopy coupled with image analysis which enabled ...
The application of disperse systems in environmental engineering / Primena disperznih sistema u inženjerstvu zaštite životne sredine
(Association of Chemical Engineers of Serbia, 2003)
This paper presents the experimental results of spouted and spout-fluid bed investigations and their application in waste treatment in the food industry and the fluid-mechanical investigations of a co-current spouted bed ...
Synthesis of nanostructured boehmite powder by sol-gel method from industrial Na-aluminate solution
(Techna Srl, Faenza, 2003)
Supersaturated Na-aluminate solution from KAP's Alumina plant Bayer process was chosen, as a precursor to synthesize low sodium content nanostructured boehmite powder. Firstly, the solution, was neutralized with strong ...
