Solvothermal synthesis of Ag/ZnO micro/nanostructures with different precursors for advanced photocatalytic applications
(Elsevier, 2017)
Micro/nanostructured systems based on metallic oxide (ZnO) with noble metal (Ag) on the surface (Ag/ZnO) are synthesized by solvothermal method from zinc nitrate hexahydrate (Zn(NO3)2·6H2O), zinc acetate dehydrate ...
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 ...
Safety and Ergonomic Design Issues of Certain Types of Robots
(Nova Science Publishers, 2017)
The role of robots is to replace or assist humans in performing the tasks that are unsafe, repetitive and energy demanding. Almost every day the number of tasks performed by robots instead of humans, or in cooperation with ...
Synthesis and investigation of BiSbTeSe single crystal doped with Zr produced using Bridgman method / Síntesis e investigación del mono cristal BiSBTeSe dopado con Zr obtenido mediante el método de Bridgman
(Centro Nacional de Investigaciones Metalúrgicas, 2017)
Single crystal ingot of BiSbTeSe doped with Zr was synthesized using Bridgman method. Energy dispersive spectrometry (EDS) analysis was used to determine chemical composition of studied samples as well as to check and ...
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 ...
The influence of m-aminobenzoic acid on electrochemical synthesis and behavior of poly(aniline-co-(m-aminobenzoic acid)
(Springer, Dordrecht, 2017)
Poly(aniline-co-(m-aminobenzoic acid)) was synthesized electrochemically at graphite electrode under galvanostatic conditions. Aqueous electrolyte for synthesis was consisted of HCl and different amount of aniline and ...
