On the kinetics of the hydrogen evolution reaction on zinc in sulfate solutions
(Belgrade : Serbian Chemical Society, 2001)
The kinetics and mechanism of the hydrogen evolution reaction (her) were studied on zinc in 1.0 mol dm-3 Na2SO4 at 298 K, in the pH range 4.4 - 10. It was found that a combination of classical potentiostatic steady-state ...
Kalcijum/kobalt hidroksiapatit nanočestice u regeneraciji osteoporotične kosti donje vilice
(Beograd : Institut tehničkih nauka, 2009)
Osteoporoza kao bolest savremene civilizacije postaje sve aktuelnija u stomatologiji. Jedan od trendova u nalaženju rešenja je u oralnoj implantologiji kroz primenu biomaterijala sa magnetnim česticama. U ovoj studiji ...
Photoacoustic properties of single crystal PbTe(Ni)
(Belgrade : International Institute for the Science of Sintering, 2007)
Single crystals of PbTe(Ni) were investigated by the photoacoustic method. They were produced using the Bridgeman method. These crystals have a sodium chloride cubic lattice and could be cleaved paralel to the plane ...
Polyaniline as possible anode materials for the lead acid batteries
Electrochemically formed thin film polyaniline (PANI) anode and lead dioxide (PbO2) cathode, obtained from sulfuric acid solution, for potential applications as electrode materials in PANI|H2SO4|PbO2 aqueous based rechargeable ...

Paper presented at the conference Материаловедение тугоплавких соединений: достижения и проблемы, Киев, Украина, 27-29 мая 2008.
A review of recent developments in the synthesis procedures of lithium iron phosphate powders
Olivine structure LiFePO4 attracted much attention as a promising cathode material for lithium-ion batteries. The overwhelming advantage of iron-based compounds is that, in addition to being inexpensive and naturally ...
Far-infrared spectroscopy of PbTe doped with iron
(Belgrade : Serbian Chemical Society, 2002)
Far infrared reflection spectra, at room and liquid nitrogen temperature, of PbTe single crystals doped with iron are presented. Plasma minima were observed at about 160 cm–1 and 180 cm–1 for room and liquid nitrogen ...
Microstructure and dielectric properties of BaTiO3 doped with Er2O3, Yb2O3 and Ho 2O3
(Faenza : ISTEC-CNR, 2008)
Doped barium-titanate ceramic is attracting much interest for its application as resistors with a positive temperature coefficient of resistivity (PTCR), multilayer ceramic capacitors (MLCC), thermal sensors etc. In this ...
Procesiranje mikrosfera poli-D,L-laktid-a u koje je inkorporiran protein
(Beograd : Institut tehničkih nauka SANU, 2007)
U svetu trenutno postoji značajna potreba za otkrićem biodegradabilnih mikrosfera kao sistema za kontrolisanu dostavu medikamenata. Glavni nedostatak tradicionalnog načina doziranja medikamenata se ogleda u potrebi za ...
Densification rate and phase structure changes during sintering of zinc titanate ceramics
Densification rate and phase structure changes during sintering of nanosized ZnTiO3 were studied. Sintering was performed in a dilatometer in two regimes: the first to 900 °C (heating rates 5, 10 and 15 °C/min) and the ...
