The influence of mechanical activation on sintering process of BaCO3-SrCO3-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2012)
In this article the influence of mechanical activation on sintering process of bariumstrontium-titanate ceramics has been investigated. Both non-activated and mixtures treated in a planetary ball mill for 5, 10, 20, 40, ...
Kreiranje morfologije i veličine čestica ZnO prahova
(Beograd : Savez inženjera i tehničara Srbije, 2012)
U ovom tekstu objašnjeni su postupci sinteze prahova ZnO i mogućnosti da se tim sintezama morfologija i srednja veličina čestica kreiraju od mikrometarskih štapića do nanometarskih sfernih čestica. Primenjene su dve metode ...
Structural and magnetic properties of mechanochemically synthesized nanosized yttrium titanate
(Belgrade : Association of the Chemical Engineers of Serbia, 2012)
Nanosized perovskite YTiO3 with the mean crystallite size of 18 nm was synthesized for the first time by mechanochemical treatment. The mechanochemical solid state reaction between commercial Y2O3 powder and mechanochemically ...
Study of dielectric behavior and electrical properties of hematite α-Fe2O3 doped with Zn
(Belgrade : International Institute for the Science of Sintering, 2012)
The effects of Zn-doping on the dielectric behavior and electrical properties of bulk α-Fe2O3 have been studied. X-ray diffraction analysis revealed the presence of two phases in all samples: hematite and spinel ZnFe2O4, ...
Electrochemically deposited nano fibrous polyanilne for amperometric determination of glucose
(Bucharest : National Institute of Materials Physics, 2012)
Electrochemical deposition of polyaniline (PANI) on graphite electrode was performed galvanostaticaly at constant current density in the range of 1.0 – 5.0 mA cm-2 from aqueous acidic electrolyte containing aniline monomer. ...
Primena polianilina u zaštiti metala od korozije
(Beograd : Inženjersko društvo za koroziju, 2012)
Polianilin je najproučavaniji elektroprovodni polimer. Ova popularnost polianilina je posledica jedinstvenih svojstava, delom nasleđenih od polimerne prirode, a delom ostvarenih provodljivošću. Najvažnija svojstva polianilina: ...
Mechanochemically Synthesized CaO ZnO Catalyst For Biodiesel Production
(Elsevier, 2012)
The transesterification of triglycerides (vegetable oil) with methanol using CaO·ZnO mixed oxides catalyst were conducted to produce FAME (Fatty Acid Methyl Esters, i.e. biodiesel). Catalyst was synthesized by ball milling ...
Structural and magnetic properties of mechanochemically synthesized nanocrystalline titanium monoxide
(Belgrade : Association of the Chemical Engineers of Serbia, 2012)
Nano-sized titanium monoxide (TiO) powder was prepared by mechanochemical synthesis. A mixture of commercial Ti and TiO2 (rutile) powders with the molar ratio of 1:1 was milled in a planetary ball mill for 5, 10, 20, 30 ...
Electrochemical characteristics of polyaniline/lead-dioxide power source
(Hunedoara : University Politehnica Timisoara, Faculty of Engineering Hunedoara, 2012)
Polyaniline (PANI) anode, electrochemically formed on graphite from aniline containing sulfuric acid solution, and electrochemically formed thin film lead dioxide cathode, were investigated for possible applications as ...
Determination of Particle Size Distributions by Laser Diffraction
(Beograd : Savez inženjera i tehničara Srbije, 2012)
The paper deals with the main principles of determination of particle size distribution using Mastersizer 2000, Malvern Instruments Ltd., UK. On the example of several problems we have demonstrated that the method is not ...
