Morfološke i elektrohemijske karakteristike prahova LiFePO4 sintetisanih u prisustvu različitih karboksilnih kiselina / Morfological and electrochemical properties of LiFePO4 powders synthesized in presence of different carboxylic acids
(Belgrade Univerzitet u Beogradu, Fakultet za fizičku hemiju, 2017)
Predmet istraživanja ove doktorske disertacije je ispitivanje mogućnosti dobijanja prahova litijum gvožđe(II) fosfata (LiFePO4) novim i modifikovanim načinima sinteze. Zahvaljujući svojoj sposobnosti da reverzibilno ...
Sol-gel synthesis of Li2FeSiO4/C
(Belgrade : Institute of Technical Sciences of SASA, 2013)
Lithium transition-metal orthosilicates with general formula Li2MSiO4 (M = Fe, Mn, Co, etc.) have attracted a lot of interest due to their potentially high theoretical capacities arising from the possibility of the extraction ...
Novel amino modified GMA-EGDMA-m-PMMA monolith for efficient cationic pollutant removal
(Belgrade : Serbian Ceramic Society, 2016)
Novel macro/micro-porous monolith material containing surface amino functional groups was developed for efficient cationic pollutant removal. The monolith was prepared by copolymerization process of monomers glycidyl ...
Aerosol-assisted low-temperature processing of colloidal TiO2 nanoparticles: two different manners for improving the optical properties
(Belgrade : Institute of Technical Sciences of the Serbian Academy of Sciences and Arts, 2011)
In order to preserve unique properties of TiO2 nanoparticles towards their surface modification, two different approaches of low temperature aerosol-assisted processing were performed. Both were based on colloid precursor ...
Synthesis of the Nanostructured YAP:Ce via Spray Pyrolysis by Polymeric Precursor Solution
(Belgrade : Materials Research Society of Serbia, 2011)
The yttrium aluminum system (Y2O3-Al2O3) includes three compounds: yttrium aluminum garnet (Y3Al5O12, YAG), yttrium aluminum perovskite (YAlO3, YAP) and yttrium aluminum monoclinic (Y4Al2O9, YAM). YAP doped with Ce is well ...
Electrical Properties of Sintered Magnesium- titanate Ceramics
(Belgrade : Serbian Ceramic Society, 2012)
Mixtures of MgO and TiO2 were mechanically activated in a planetary ball mill for different time intervals. Thus obtained powders were sintered in a furnace for 2 h at temperature of 1300 °C in air atmosphere. Raman ...
Oxygen Reduction on Polycrystalline Pt Electrode Modified by Acetonitrile in Neutral Electrolyte
(Nice : International Society of Electrochemistry, 2010)
Two step sintering of ZnTiO3 nanopowder
(Belgrade : International Institute for the Science of Sintering, 2017)
Metastable nanopowder ZnTiO3 was pressed into cylindrical compacts at 200 MPa. Compacts were treated by conventional heating with isothermal holding at 931°C for 10 minutes, 25 minutes and 40 minutes. ZnTiO3 compacts were ...
Pseudobrookite TiFe2O5 nanostructured thick films
(Belgrade : Institute of Technical Sciences of SASA, 2015)
TiO2 (anatase) and Fe2O3 (hematite) nanopowders were mixed in the weight ratio 1:1.5 and 1:2 and homogenized in a planetary ball mill for an hour. After that pastes were prepared of the two powder mixtures, organic vehicle ...
Simultaneous enhancement of natural sunlight- and artificial UV-driven photocatalytic activity of a mechanically activated ZnO/SnO2 composite
(Royal Society of Chemistry, 2017)
Mechanical milling of commercial ZnO and SnO2 was used to produce a ZnO/SnO2 composite with a high density of surface defects; in particular, zinc interstitials (Zni) and oxygen vacancies (VO). To determine the impact of ...
