A review of recent developments in the synthesis procedures of lithium iron phosphate powders
(Elsevier, 2009)
Olivine structure LiFePO4 attracted much attention as a promising cathode material for lithium-ion batteries. The overwhelming advantage of iron-based compounds is that, in addition to being inexpensive and naturally ...
Influence of MgO addition on the synthesis and electrical properties of sintered zinc-titanate ceramics
(Elsevier, 2009)
Starting mixtures of ZnO, TiO2 and MgO (0, 1.25 and 2.5 wt.% MgO) powders were mechanically activated for 15 min in a planetary ball mill. The powders obtained were sintered non-isothermally to temperatures between 800 and ...
Modeling boron separation from water by activated carbon, impregnated and unimpregnated
(Roma : Società chimica italiana, 2000)
The sorption of boron from boric acid water solution by impregnated activated carbon has been studied Barium, calcium, mannitol, tartaric acid and citric acid were used as chemical active materials. All processes were ...
Injectable polydimethylsiloxane-hydroxyapatite composite cement
(Bio-Medical Materials and Engineering, 2003)
An injectable polydimethylsiloxane/hydroxyapatite (PDMS/HAp) composite cement was synthesised using linear PDMS and HAp (particles of about 100 nm in size) of different mass fractions. The effect of HAp mass fraction (5-60 ...
Structural analysis of Zn2TiO4 doped with MgO
(Springer, 2009)
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 ...
Photoacoustic characterization of natural mineral pyrite (FeS2)
(Springer, 2008)
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 ...
Formation of magnesium titanates
(Springer, 2009)
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
(Elsevier, 2009)
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 ...
Optical properties of PbTe and PbSnTe doped with Cr
(Elsevier, 2009)
Single crystal samples of PbTe and PbSnTe doped with Cr were made using the Bridgman technique. Far infrared diagrams of PbTe samples doped with 0.4 at.%, 0.8 at.% and 1 at.% Cr and also of Pb0.9Sn0.1Te doped with 0.4 at.%, ...
Cell response to intraperitoneal pdms/HAp composite implant / Ćelijski odgovor na intraperitonealni implant kompozita pdms/HAp
(Niš : University of Niš, Faculty of Medicine, 2005)
Siloxane polimers have been widely used in biomedicine and pharmacy due to their biocompatibility. Hydroxyapatite (HAp) is a natural constituent of bones, and therefore widely used in maxillofacial and orthopedic surgery. ...
