Intrinsic resistivity of sintered Nickel Manganite vs. powder activation time and density
(Belgrade : International Institute for the Science of Sintering, 2008)
In this work the DC resistivity of sintered nickel manganite NiMn2O4 (NTC thermistor material) was studied as a function of additional powder activation time in a planetary ball mill (0, 5, 15, 30, 45 and 60 min). The ...
Synthesis of BaTiO3 from a mechanically activated BaCO 3-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2008)
In this article the solid state reaction of BaTiO3 formation from a mechanically activated BaCO3-TiO2 system has been investigated. An equimolar mixture of BaCO3 and TiO2 powders was activated in a planetary ball mill in ...
Far infrared properties of iron doped single crystal PbTe
(Măgurele : National Institute of Research and Development for Optoelectronics, 2008)
Far infrared reflectivity spectra of single crystal PbTe samples doped with 0.2 at% Fe were measured in the temperature range between 10 K and 300 K. These spectra show very sharp and narrow dips below 120 cm-1. The ...
Nanomaterial N-CP/DLPLG as potentional tissue graft in osteoreparation in combination with bone marrow cells on subcutaneous implantation model
(Belgrade : Association of the Chemical Engineers of Serbia, 2008)
The need for bone graft materials in osteoreparation is tremendous. Many researches have shown that calcium-phosphate bioceramics have good biocompatibility and osteoconductivity. We used nanocomposite biomaterial calcium ...
Dobijanje čistih i kompozitnih prahova od poli-L-laktida i poli-D,L-laktida modifikovanom precipitacionom metodom i njihova karakterizacija
(Belgrade : University of Belgrade, Faculty of Technollogy and Metallurgy, 2008)
U svetu trenutno postoji značajna potreba za otkrićem biodegradabilnih mikro i nanosfera koje se koriste kao sistemi za kontrolisanu dostavu medikamenata. Glavni, ali ne i jedini nedostatak tradicionalnog načina doziranja ...

(8th World Biomaterials Congress 2008, WBC 2008; Amsterdam; Netherlands; 28 May 2008 - 1 June 2008, 2008)
Elektrohemijski izvori energije sistema metal ׀ elektroprovodni polimer na bazi vodenih rastvora
(Belgrade : University of Belgrade, Faculty of Technology and Metallurgy, 2008)
U ovom radu su ispitane mogućnosti primene polimera polianilina (PANI) i polipirola (pPu) kao katodnih materijala u kombinaciji sa anodama od Zn, Mg i Al za potencijalnu primenu u elektrohemijskim izvorima struje (EIE). ...
Sinteza i luminescentne karakteristike nanostrukturnih Y2O3:Eu3+ prahova
(Beograd : Društvo za istraživanje materijalaBeograd : Institut tehničkih nauka SANU, 2008)
Nanostrukturni prahovi Y2O3 dopirani sa 5 i 10 at% europijuma su sintetisani metodom sprej pirolize na 900°C i naknadno termički tretirani na temperaturama od 1000 do 1200°C 12 h. Strukturne i emisione karakteristike prahova ...
