Modified glycine nitrate procedure synthesis and properties of nanostructured Ca1-xGdxMnO3 (x=0.05; 0.1; 0.15; 0.2)
(Belgrade : Serbian Ceramic Society, 2021)
Nanocrystalline manganites Ca1-xGdxMnO3(x=0.05, 0.1, 0.15, 0.2) were synthesized by a modified glycine-nitrate procedure. The subsequent studies were focused on the structural, microstructural and magnetic changes of the ...
Comparative study of the effects of different nanomaterials on the viability of human osteoblast-like cells
(Belgrade : Materials Research Society of Serbia, 2012)
The aim of this study was to compare the effects of two types of nanomaterials, cobalt-exchanged hydroxyapatite (CoHAp) and calcium phosphate/poly-(DL-lactide-co-glycolide) (CP/PLGA), on the viability of Saos-2 osteoblast-like ...
Effect of processing parameters on NaGdYF4:Yb,Er UCNPs structural, morphological and optical properties
(Belgrade : Institute of Technical Sciences of SASA, 2021)
Synthesis of monosized and spherical Up-Converting NanoParticles (UCNPs) with biocompatible surface are of a great interest because of their potential application in biomedicine as biomarkers or drug delivery systems. Among ...
Formation of magnesium titanates
(Springer, 2009)
The paper examines the phase formation in the mechanochemical treatment and subsequent annealing of TiO 2 and MgO mixtures. It is established that the MgTiO 3 phase forms during annealing of the above powder mixtures at ...
On the Role of Poly-Glutamic Acid in the Early Stages of Iron(III) (Oxy)(hydr)oxide Formation
(Basel : MDPI AG, 2021)
Nucleation of minerals in the presence of additives is critical for achieving control over the formation of solids in biomineralization processes or during syntheses of advanced hybrid materials. Herein, we investigated ...
Dielectric characteristics of polymer nanocomposites based on PVDF and mechanically activated ZnO powder
(Belgrade : Serbian Ceramic Society, 2021)
ZnO powder was mechanically activated for 10 and 30 minutes in a high energy planetary ball mill, and mixed with 2 wt% PVDF solution to obtain nanocomposite films (50 μm) by casting. ZnO powder activated for 10 and 30 ...
The success rate of hydroxyapatite nanoparticles coated with bioresorbable polymers in a biological environment
(Belgrade : Materials Research Society of Serbia, 2014)
Hydroxyapatite (HAp) nanoparticles coated with bioresorbable polymers have been successfully used as filler, carriers of antibiotics, vitamins and stem cells in bone tissue engineering. Interactions in the microenvironment ...
Statistical Analysis of the Influence of Temperature on Microstructure Contact Surfaces on BaTiO3 -ceramics Doped with Ho2O3
(Belgrade : Serbian Ceramic Society, 2014)
The materials based on BaTiO3 can be controlled using different technological parameters and different additives. We investigate the influence of different temperature levels of sintering (1320°C, 1350°C and 1380°C) on the ...
NIR photo-driven upconversion in NaYF4:Yb,Er/PLGA particles for in vitro bioimaging of cancer cells
(Elsevier, 2018)
Lanthanide-doped fluoride up-converting nanoparticles (UCNPs) represent the new class of imaging contrast agents which hold great potential for overcoming existing problems associated with traditionally used dyes, proteins ...
Surface characterisation of PLLA polymer in HAp/PLLA biocomposite material by means of nanoindentation and artificial neural networks
(Maney Publishing, 2010)
In this paper, the mechanical properties of polymer matrix phase (modulus of elasticity, yield stress and work hardening rate) have been determined using combined methods such as nanoindentation, finite element modelling ...
