Simultaneous anodization/anaphoretic electrodeposition synthesis of nano calcium phosphate/titanium oxide composite coatings assisted with chitosan oligosaccharide lactate
(Elsevier, 2020)
In this paper novel in situ one-step simultaneous anaphoretic deposition process of amorphous calcium phosphate (ACP) and titanium oxide (TiOx) with and without chitosan oligosaccharide lactate (ChOL) on titanium substrate ...
Sonochemical synthesis of up-converting β-NaYF4: Yb, Er nanoparticles
(Belgrade : Materials Research Society of Serbia, 2021)
Up-converting nanoparticles (UCNPs) with unique ability to convert NIR to VIS light (anti-Stokes process) have a wide application in optoelectronics, forensic, security labeling and biomedicine. Over the past few years ...
Niobium doping effect on BaTiO3 structure and dielectric properties
(Elsevier, 2020)
The effect of Nb on the microstructure and dielectric properties of BaTiO3 ceramics was investigated. The Nb/Mn–BaTiO3 ceramics were prepared using a conventional solid-state method. The concentration of Nb varied from 0.1 ...
Stochastic Time Response and Ultimate Noise Performance of Adsorption-Based Microfluidic Biosensors
(Basel : MDPI AG, 2021)
In order to improve the interpretation of measurement results and to achieve the optimal performance of microfluidic biosensors, advanced mathematical models of their time response and noise are needed. The random nature ...
Influence of BaTiO3/Fe2O3 addition on crystallization and polymorphism of PDVF polymer matrix followed by DSC-TG
(Central and Eastern European Committee for Thermal Analysis and Calorimetry (CEEC-TAC), 2021)
Ceramic/polymer dielectric composites are widely used as components for electric devices, mainly because of their high chemical stability, mechanical strength, and flexibility. In order to increase dielectric permittivity, ...
Influence of anodization voltage on photocatalztic activity of TiO2 nanotubes
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2021)
TiO2 under UV light generates charge carriers (electrons and holes) that take part in the process of decomposition of pollutants, which is a well-known fact for the past few decades. For this reason, TiO2 is used for ...
Synthesis of Ce/Ru Doped ZnO photocatalysts to the degradation of emerging pollutants in wastewater
(Belgrade : Materials Research Society of Serbia, 2019)
Semiconductor nanoparticles (NPs) and nanowires (NWs) of doped ZnO system with different dopant content have been synthesized by Polyol-Mediated Thermolysis (PMT) process and Vapour-Solid (VS) reaction. The average crystallite ...
Electrical Characteristics of Ho doped BaTiO3 Ceramics
(Belgrade : Serbian Ceramic Society, 2019)
In this paper, electrical characteristics of Ho2O3 doped BaTiO3 ceramics were shown, using new method for measuring samples. The BaTiO3 doped samples were sintered at 1320°C for 4 hours. The concentration of the additives ...
X-ray spectra, electron structure and physical properties of the Ce2ScSi2 and СеScSi compounds
(Belgrade : Materials Research Society of Serbia, 2019)
Energy structure of the valence band of the Ce2ScSi2 and СеScSi compounds was studied by the methods of the high-energy spectroscopy (XPS, XES and XAS). Dependence of magnetic susceptibility χ(Т) of the Ce2ScSi2 compound ...
