Dirigovana sinteza nanostrukturnih oksidnih prahova sa gledišta razvoja materijala zadatih svojstava
(Belgrade : University of Belgrade, Faculty of Technology and Metallurgy, 2004)
Razvoj novih materijala, kao i nastojanja za iskorišćenjem njihovih tehnološki atraktivnih karakteristika doveli su do intenzivnije sinteze novih ultrafinih struktura i nanofaznih prahova. Istraživanja obuhvaćena radom ...
Influence of the HAp ratio on the thermodynamic and kinetic parameters of PDMS/HAp composites cross-linking
(Contemporary Studies in Advanced Materials and Processes, 4th Yugoslav-Materials-Research-Society Conference, Sep 10-14, 2001, Herceg Novi, Yugoslavia, 2003)
Injectable and gas-permeable composite cements, polydimethylsiloxane/hydroxyapatite (PDMS/HAp), were synthesized using bi-component polysiloxane precursors (RTV-A and RTV-B), which react by hydrosilylation, and different ...
Ultrasound synthesis of poly-dl-lactide-co-glycolide/hydroxyapatite core-shell nano-spheres
(8th World Biomaterials Congress 2008, WBC 2008; Amsterdam; Netherlands; 28 May 2008 - 1 June 2008, 2008)
Magnetic properties of nanostructured SiOo2:Eu3+ powders
(Belgrade : Serbian Chemical Society, 2006)
Eu-doped silica nanoparticles with different concentrations of europium (3% 6%and 15at.%) were prepared by a hydrothermal procedure. Light scattering measurements of the silica colloids as well as TEM microscopy, revealed ...
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). ...
Obtaining nano calcium phosphate/poly(dl-lactide-coglycolide) composite biomaterial by sonochemical deagglomeration
(Belgrade : Institute of Technical Sciences of SASA, 2007)
Nanoparticles have several advantages over the microparticles in interactions of the
biomaterial with the organism. The response of the organism depends on the interaction of the
biomaterial with the surrounding tissue ...
Morphological changes of poly(DI-lactide-co-glycolide) nano-particles containing ascorbic acid during in vitro degradation process
(Wiley, 2008)
Poly(dl-lactide-co-glycolide) powder composed of uniform particles with the mean particle size in the range of 110-170 nm was obtained from commercial granules. Ascorbic acid in different concentrations was encapsulated ...
Far infrared spectroscopy of Pb0.85Sn0.15Te alloy doped with Ni
(Carl Hanser Verlag, 2008)
Far infrared reflectivity spectra of single crystal Pb 0.85Sn0.15Te doped with Ni were measured in the temperature range between 10 K and 300 K. Analysis of the experimental spectra was made using a fitting procedure based ...
Thermal diffusivity of sintered 12CaO×7AI2O3
(Springer, 2008)
The thermal diffusivity and free carrier diffusion coefficient of 12CaO×7 Al2O3 (C12A7) sintered for different times in air or hydrogen followed by treatment with UV light were determined from photoacoustic phase and ...
Sintering of mechanically activated Zno-TiO 2 powders
(Springer, 2008)
Zinc oxide and titanium dioxide powders mixed in an equimolar ratio are mechanically activated in a planetary ball mill and sintered under nonisothermal and isothermal conditions. Nonisothermal sintering is studied using ...
