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, ...
Mechanochemical preparation and characterization of CaO·ZnO used as catalyst for biodiesel synthesis
(Elsevier, 2012)
In this study, the synthesis of biodiesel or fatty acid methyl esters (FAME) from sunflower oil and methanol using CaO·ZnO catalyst was investigated. Catalyst was synthesized by ball milling of Ca(OH)2 and ZnO powder mixture ...
The contribution of fractal nature to BaTiO3-ceramics microstructure analysis
(Elsevier, 2012)
The structure of BaTiO3 based materials can be controlled by using different technological parameters and different additives. In this paper, microstructure and dielectrical properties of Er2O3 doped BaTiO3-ceramics, ...
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. ...
Processing Route to Fully Dense Nanostructured HAp Bioceramics: From Powder Synthesis to Sintering
(Hoboken, NJ : John Wiley & Sons, 2012)
The study is devoted to the processing of hydroxyapatite (HAp) nanopowder to develop fully dense nanostructured bioceramics by pressureless sintering. The sintering behavior of stoichiometric HAp prepared by hydrothermal ...
Fluctuations of the number of adsorbed molecules in biosensors due to stochastic adsorption–desorption processes coupled with mass transfer
(Elsevier, 2012)
We derived a simple theory of fluctuations of the equilibrium number of adsorbed molecules in biosensors, caused by the stochastic nature of adsorption–desorption (AD) processes coupled with mass transfer. The two-compartment ...
Poly(d,l-lactide-co-glycolide)/hydroxyapatite core–shell nanospheres. Part 4: A change of the surface properties during degradation process and the corresponding in vitro cellular response
(Elsevier, 2012)
The surface properties of PLGA/HAp core–shell nanoparticles loaded with clindamycin obtained by an ultrasonic processing method and their changes under the simulated physiological conditions during the degradation process ...
