Comparative morphological and crystallographic analysis of copper powders obtained under different electrolysis conditions
(Elsevier, 2019)
Production of copper powders by the potentiostatic electrolysis under different hydrogen evolution conditions was investigated. Copper powders were characterized by the scanning electron microscope (SEM), X-ray diffraction ...
The influence of gamma radiation on the molecular weight and glass transition of PLLA and HAp/PLLA nanocomposite
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2010)
The influence of gamma radiation on the molecular weight and glass transition behaviour of poly-L-lactide (PLLA) and hydroxyapatite/poly-L-lactide (HAp/PLLA) nanocomposite has been studied Since PLLA exposed to high-energy ...
Intergranular area microalloyed aluminium-silicate ceramics fractal analysis
(Belgrade : International Institute for the Science of Sintering, 2013)
Porous aluminium-silicate ceramics, modified by alloying with magnesium and microalloying with alluminium belongs to a group of advanced multifunctional ceramics materials. This multiphase solid-solid system has predominantly ...
The solvothermal synthesis of magnetic iron oxide nanocrystals and the preparation of hybrid poly(L-lactide)-polyethyleneimine magnetic particles
(Elsevier, 2013)
We report a simple and green procedure for the preparation of magnetic iron oxide nanocrystals via solvothermal synthesis. The nanocrystal synthesis was carried out under mild conditions in the water–ethanol–oleic acid ...
Bifunctional catalytic activity of Zn1−xFexO toward the OER/ORR: seeking an optimal stoichiometry
(Royal Society of Chemistry, 2020)
Eco-friendly and rapid microwave processing of a precipitate was used to produce Fe-doped zinc oxide (Zn1−xFexO, x = 0, 0.05, 0.1, 0.15 and 0.20; ZnO:Fe) nanoparticles, which were tested as catalysts toward the oxygen ...
Enhanced high-temperature electrical response of hydroxyapatite upon grain size refinement
(Elsevier, 2015)
Correlation between high-temperature electrical response and microstructural properties of dense hydroxyapatite with average grain size from micrometer to nanometer level in heating/cooling cycle was investigated. Grain ...
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 ...
Ideal efficiency of resonant cavity-enhanced perovskite solar cells
(Springer Science and Business Media LLC, 2020)
Perovskite solar cells (PSCs) have attracted significant attention in recent years due to the rapid increase in device efficiency (reaching over 25% in 2019), ease of fabrication, and the potential to produce low-cost ...
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 synthesis and corrosion behavior of polyaniline-benzoate coating on copper
(Elsevier, 2011)
Electrochemical polymerization of polyaniline (PANI) coating on copper electrode was performed galvanostatically in the current density range between 0.50 and 1.25 mA cm−2, from aqueous solution of 0.3 mol dm−3 sodium ...
