Influence of Co2+ ions on photocatalytic properties of MgFe2O4 ferrites
(Belgrade : Institute for Multidisciplinary Research, 2019)
In this work, spinel magnesium cobalt ferrites (CoxMg1-xFe2O4, x = 0.0, 0.1, 0.3, 0.5, 0.7, 0.9) were synthesized by a sol-gel combustion method. Magnesium nitrate, cobalt nitrate and iron nitrate were used as oxidizers ...
Density of the ZnTiO3 nanopowder as a loose powder and as a compact obtained by different methods
(Belgrade : Serbian Ceramic Society, 2013)
Nanopowder density, as well as compact density, is due to powder particle size, different in their values, compared to micron powders. Also, the technique used for density determination induces large mutual value discrepancies. ...
Hydrothermal synthesis of nanostructured rare earth oxide – based phosphors
(Belgrade : Agencija FORMAT, 2012)
Synthesis of nanostructured rare earth oxide-based phosphor particles with enhanced optical characteristics leads to the creation of the new photonic devices with diverse applications. Tailoring of the phosphors quality ...
NIR photo-driven upconversion in amino and carboxyl functionalized NaYF4:Yb,Er particles for in vitro cancer cell imaging
(London : Conference Series IIc, 2019)
Lanthanide-doped fluoride up-converting nanoparticles (UCNPs) represent the imaging contrast agents which hold great potential for overcoming existing problems associated with traditionally used dyes, proteins and quantum ...
Humidity sensing potential of iron manganite (FeMNO3)
(Budapest : [s. n.], 2019)
Though different metal oxide systems have been investigated and applied in humidity sensing as resistive or capacitive ceramic humidity sensors new materials remain the subject of much research. Iron manganite (FeMnO3) has ...
Determination of glucose using polyaniline modified electrode
(Belgrade : Institute of Technical Sciences of the Serbian Academy of Sciences and Arts, 2011)
Sensor electrode was formed by immobilization of glucose oxidase (GOx) on polyaniline (PANI), electrochemically synthesized on graphite electrode from aqueous hydrochloride acid electrolyte containing aniline monomer by ...
Failures of Brass Condenser Tubes / Lomovi kondenzatorskih cevi od mesinga
(Belgrade Society for Structural Integrity and Life; IMS Institute, 2016)
Causes of failure of brass condenser tubes (CuZn28Sn1) in a thermal power plant in Serbia are analysed. Results of testing by Fourier transformed infrared spectroscopy (FTIR) have indicated the presence of ammonia and ...
On the synthesis of 3-cyano-6-hydroxy-4-methyl-2-pyridone at room temperature
(Belgrade : Engineers Society of Corrosion, 2019)
Milling of cyanoacetamide and acetoacetic ester as reactants, in the presence of KOH as the catalyst and ethanol as a viscous control agent (VCA) was performed in a planetary ball mill with the goal of investigating the ...
Electrochemical behavior of polyaniline in chloride/citrate electrolyte
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2011)
Polyaniline electrode, was obtained by electrochemical polymerization at constant current density of 2.0 mA cm-2 from aqueous solution of 1.0 mol dm-3 HCl containing 0.25 mol dm-3 aniline. Electrochemical characterization ...
The effect of mechanical activation on synthesis and properties of MgAl2O4 ceramics
(Societa ceramica italianaPolitecnico di Torino, 2019)
Magnesium aluminate, MgAl2O4, and other alumina-based spinels are refractory ceramics with high hardness and resistance to chemical attack while also being possible microwave dielectrics. Pure MgAl2O4 can be optically ...
