Biodegradable polymer/hydrogel composite for controlled delivery of cationic formulations
(Belgrade : Institute of Technical Sciences of SASA, 2017)
Composites of biodegradable polymers and hydrogels are promising materials for controlled delivery systems with prolonged drug release. In this contribution, we present an innovative implant design comprising poly(DL-lac ...
Facile synthesis of hydrophilic polymer-capped upconverting NaYF4:Yb,Er particles
(Belgrade : Serbian Ceramic Society, 2017)
Over the last decade, solvothermal decomposition of organometallic compounds has been indicated as one of the most convenient method for the synthesis of monodisperse lanthanide doped upconverting fluorides. Due to their ...
In-vitro visualization of primary tumor cells using up-conversion nanophosphors
(Belgrade : Serbian Ceramic Society, 2017)
For such purpose, Ln-UCNPs should have specific morphological characteristics and efficient luminescence response. In this work, a biocompatible and water dispersible NaYF4:Yb,Er@PLGA nanoparticles synthesized using a ...
Application of multiparametric cardiac measurement system in ejection fraction calculation
(Belgrade : Institute of Physics Belgrade, 2017)
Ejection fraction (EF) is the most used parameter for characterisation of Heart Failure (HF) condition. EF is commonly calculated using echocardiography, which is an expensive non–invasive method and not used in primary ...
Zinc oxide-based materials with enhanced sunlight-driven photo- and photo-electro-catalytic activity
(Belgrade : Serbian Ceramic Society, 2017)
Current trend in photocatalysis is to develop efficient semiconductors which can be activated by absorbing sunlight. Which wavelength of sunlight will be absorbed depends on the semiconductor band gap; semiconductors with ...
The slag based adsorbents for Cu2+ removal from aquatic solutions
(Belgrade : Materials Research Society of Serbia, 2017)
This study aims to understand the kinetic, thermodynamic and mechanism of Cu2+ adsorption onto unmodified electric arc furnace slag (EAFS) and alkali modified EAFS. The adsorption process was investigated via a batch reactor ...
Characterization of pressure-less sintered MgO-Al2O3-SiO2-TeO2 system
(Belgrade : Materials Research Society of Serbia, 2017)
In this study, sintering of two systems was investigated in parallel, pure cordierite 2MgO:2Al2O3:5SiO2, and cordierite with addition of 5 mass % TeO2. Green bodies were prepared from powder mixtures mechanically activated ...
Highly selective anticancer activity of core shell particles based on hydroxyapatite, chitosan lactate and different androstane derivatives
(Belgrade : Materials Research Society of Serbia, 2017)
Hybrid systems based on nano hydroxyapatites (HAp) are the subject of numerous studies in preventive and regenerative medicine. Special interests are directed towards the creation of a system based on HAp for use in a ...
Electrical properties of doped BaTiO3 Ceramics
(Belgrade : Serbian Ceramic Society, 2017)
The electrical resistivity and PTCR (Positive Temperature Coefficient of Resistivity) effect doped BaTiO3 ceramics with different dopant were investigated in this paper, The content of additive in doped samples were ranged ...
Synthesis and Characterization of Multifferoics 16%(Fe2O3)4%(BaCO3)80%(BaTiO3)
(Belgrade : Serbian Ceramic Society, 2017)
The initial powder (16 % Fe2O3, 4 % BaCO3, 80 % BaTiO3) was mechanically activated in a planetary mill for 20, 80, 120, 160, 200 and 220 minutes in air. Modified Faraday method was used to perform magnetization measurements ...
