Hydrothermally processed 1D hydroxyapatite: Mechanism of formation and biocompatibility studies
(Materials Science and Engineering: C, 2016)
Recent developments in bone tissue engineering have led to an increased interest in one-dimensional (1D) hydroxyapatite (HA) nano- and micro-structures such as wires, ribbons and tubes. They have been proposed for use as ...
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 ...
Nanoparticles of cobalt-substituted hydroxyapatite in regeneration of mandibular osteoporotic bones
(Journal of Materials Science: Materials in Medicine, 2013)
Indications exist that paramagnetic calcium phosphates may be able to promote regeneration of bone faster than their regular, diamagnetic counterparts. In this study, analyzed was the influence of paramagnetic cobalt-substituted ...
Peculiarities in sintering behavior of Ca-deficient hydroxyapatite nanopowders
(Elsevier, 2012)
We report unusual sintering behavior of Ca-deficient hydroxyapatite processed with different heating rates; particularly, faster heating resulted in higher densification. We hypothesize that faster heating delays formation ...
ZnO micro and nanocrystals with enhanced visible light absorption
(Elsevier, 2012)
In this paper, we investigate the effect of the particle size and morphology on the optical properties of ZnO. A series of ZnO micro and nanocrystals were synthesized by the hydrothermal processing of zinc acetate dihydrate ...

Uticaj mehaničke energije na komponente MgO-Al2O3-SiO2-TiO2 sistema
(Beograd : Savez inženjera i tehničara Srbije, 2012)
U ovom radu je ispitivan uticaj mehaničke energije na strukturu i promene u mikrostrukturi sistema MgO-Al2O3-SiO2-TiO2. Utvrđeno je da mehanička energija pospešuje homogenizaciju polaznih komponenti, utiče na veličinu i ...
Structural and Electrical Properties of Sintered Barium-Zinc-Titanate Ceramics
(Warsaw : Institute of Physics, Polish Academy of Science, 2011)
The aim of this work was an investigation of structural and electrical properties of sintered barium-zinc-titanate ceramics. Mixtures of BaCO3, ZnO and TiO2 were mechanically activated in a planetary ball mill up to 80 ...
Preparation of smallest microparticles of poly-D,L-lactide by modified precipitation method: Influence of the process parameters
(Wiley, 2008)
Biodegradable microspheres such as those made of poly-D,L-lactide (PDLLA) are widely investigated delivery systems for drugs or antigens. The aim of this study was to examine experimental conditions in order to produce ...
Photoacoustic investigation of transport in semiconductors: Theoretical and experimental study of a Ge single crystal
(Physical Review B, 1995)
Photoacoustic (PA) heat-transmission measurements were used to study transport in a nearly intrinsic Ge single crystal. A theoretical model was developed which quantitatively describes excess carrier and thermal-wave space ...
