Mechanochemically-assisted synthesis and characterization of Zr-doped hydroxyapatite nanopowders
(Belgrade : Materials Research Society of Serbia, 2011)
Hydroxyapatite (HAp) bioceramics attract researches’ interests over the decades as a candidate for ideal bone tissue reconstruction material. Its excellent biocompatibility and bioactivity, originating from chemical ...
Nanostructured (Y1-xGdx)2O 3:Eu3+ powders obtained through aerosol synthesis
(Hoboken, NJ : John Wiley & Sons, 2010)
In this study, nanophase, spherical, polycrystalline (Y 1-xGdx)2O3:Eu3+phosphor particles were synthesized from aerosols of corresponding nitrate solutions, ultrasonically generated at 1.3 MHz frequency, and thermally ...
Microstructure evolution and sintering kinetics of ZnO
(Institut za istraživanja i projektovanja u privredi, Beograd, 2011)
The aim of this work was to analyse the kinetics and microstructure evolution of ZnO sintering process. ZnO powder was isothermally sintered (15, 30, 60, 90 and 120 min) in the temperature range from 8000C to 12000C. The ...

Efficacy of nanocrystalline bone substitute biphasic calcium phosphate/poly-DL-lactide-co-glycolide for periodontal intrabony defects filling
(Belgrade : Military Medical Academy, 2015)
Background/Aim. Different bone substitutes have been used for filling and reparation of intrabony defects. The aim of this study was to compare nanocrystalline material, biphasic calcium phosphate poly-DL-lactidecoglycolide ...
Poly(d,l-lactide-co-glycolide)/hydroxyapatite core–shell nanospheres. Part 3: Properties of hydroxyapatite nano-rods and investigation of a distribution of the drug within the composite
(Elsevier BV, 2011)
A step-by-step analysis of the formation and the drug loading of the poly(d,l-lactide-co-glycolide)/hydroxyapatite (PLGA/HAp) composite was carried out in a perspective of the following parameters: the structure, the ...
Mechanochemical synthesis of bismuth ferrite
(Technical Faculty - Copper Institute, Bor, 2013)
A powder mixture of Bi2O3 and Fe2O3 was mechanically treated in a planetary ball mill in an air from 30 to 720 minutes. It was shown that the mechanochemical formation of BiFeO3 (BFO) phase was initiated after 60 min and ...
Elektrohemijska sinteza i karakterizacija kopolimera polianilina i maminobenzoeve kiseline / Electrochemical synthesis and characterization of poly(aniline-co-(maminobenzoic acid)
