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 ...
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.%, ...
Programme and The Book of Abstracts / Eleventh Annual Conference YUCOMAT 2009, Herceg Novi, August 31 – September 4, 2009
(Belgrade : Institute of Technical Sciences of SASA, 2009)
The First Conference on materials science and engineering, including physics, physical chemistry, condensed matter chemistry, and technology in general, was held in September 1995, in Herceg Novi. An initiative to establish ...
Strukturne, morfološke i funkcionalne karakteristike nanostrukturnih oksida retkih zemalja dobijenih aerosol sintezom
(Belgrade : University of Belgrade, Faculty of Technollogy and Metallurgy, 2009)
Dobijanje ultrafinih, sferičnih, fosforescentnih čestica sa homogenom raspodelom komponenata i faza je od posebnog značaja za materijale sa primenom u savremenim optoelektronskim uređajima. Reakcija u disperznom sistemu ...
Characterization of electrochemically synthesized pani on graphite electrode for potential use in electrochemical power sources / Elektrohemijska sinteza i karakterizacija elektrode od polianilina za potencijalnu upotrebu u elektrohemijskim izvorima energije
(Engineering Society for Corrosion, Belgrade, Serbia, 2009)
Polyaniline (PANI) on graphite electrode was synthesized electrochemically under galvanostatic condition at current density of 2.0 mA cm-2 from aqueous solution of 1.0 moldm-3 HCl and 0.25 mol dm-3 aniline monomer. ...
Citrate-based zinc-polyaniline secondary cell: Part I: Optimization of the citrate/chloride electrolyte
(Springer, 2009)
Electrochemical behavior of zinc and thin polyaniline (PANI) electrodes in citrate/chloride-contained electrolyte has been investigated by the means of electrolyte composition optimization. Electrolyte contained 0.8 M ...
Influence of different degradation medium on release of ascorbic acid from poly(D,L-lactide-co-glycolide) nano- and microspheres
(Springer, 2009)
The major goals of the present study were to examine the effects of the type of release medium on the resulting drug release kinetics and to get further insight into the underlying drug release mechanisms. Spherical micro ...
Controllable synthesis of horseradish peroxidase loaded poly(D,L-lactide) nanospheres
(American Scientific Publishers, 2009)
In this work, horseradish peroxidase (HRP), a model protein, was encapsulated by the precipitation method with additional step of homogenization, using polymer poly(D,L-lactide) (PDLLA). The purpose of this study was to ...
