Structural analysis of Zn2TiO4 doped with MgO
The starting mixtures of ZnO, TiO2, and MgO (0, 1.25, and 2.5 wt.%) powders are mechanically activated in a high-energy planetary mill for 15 min and then sintered between 800 and 1100°C for 2 h. The influence of MgO ...
PDLLA Microparticles Containing BSA: Effect of Formulation Variables on Size Distribution
Poster presented at the 9th Conference of the Yugoslav Materials Research Society - YUCOMAT 2007, Herceg Novi, Crna Gora, September 10-14, 2007.
Influence of mechanical activation on BaO-ZnO-TiO2 system
(Belgrade : Institute of Technical Sciences of SASA, 2008)
The influence of mechanical activation on BaO-ZnO-TiO2 sistem was observed. Mixtures of BaO-ZnO-TiO2 were mechanically activated using high-energy planetary ball mill during 0,5, 10, 20, 40 and 80 minutes. XRD analyses ...
Photoacoustic characterization of natural mineral pyrite (FeS2)
A single p-type crystal of the mineral, pyrite (FeS2) was characterized photoacoustically using the transmission detection configuration. Photoacoustic (PA) amplitude and phase spectra were measured using a specially ...
Forming of titanium titnate
Lately a great attention is spared development of materials, possessing high stable dielectric properties. Among such materials a considerable place is occupied by titanates of metal series, including titanate of magnesium. ...
Kinetics of the hydrogen oxidation on pt modified MoOx nano-sized catalyst in the presence of carbon monoxide
(Belgrade : Institute of Technical Sciences of SASA, 2009)
Due to the importance of the HOR in fuel-cells technology, various Pt-based catalysts have been examined from the viewpoint of immunity of the electrocatalysis of the HOR from CO-poisoning of the anode catalysts. An ...
Structural and electrical properties of sintered MgTiO3 ceramics
(Faenza : ISTEC-CNR, 2008)
Ceramics for electronics play an important role in several industrial sectors. The most common way of producing these ceramics is through sintering processes from powders. The powders can be treated by mechanical activation; ...
"Thermal diffusivity and electron transport properties of NTC samples obtained by photoacoustic method
Poster presented at the Seventh Yugoslav Materials Research Society Conference - YUCOMAT 2005, Herceg Novi, Crna Gora, September 12-16, 2005.
Formation of magnesium titanates
The paper examines the phase formation in the mechanochemical treatment and subsequent annealing of TiO 2 and MgO mixtures. It is established that the MgTiO 3 phase forms during annealing of the above powder mixtures at ...
Effect of chemisorbed carbon monoxide on Pt/C electrode on the mechanism of the hydrogen oxidation reaction
The influence of poisoning of Pt catalyst by CO on the kinetics and mechanism of H2 oxidation reaction (HOR) at Pt/C electrode in 0.5 mol dm-3 HClO4, saturated with H2 containing 100 ppm CO, was examined with rotating disc ...
