Methanol electrooxidation on PtRu modified zeolite X
(International Institute for the Science of Sintering, Beograd, 2013)
Zeolite NaX (faujasite type) was used as a support for platinum-ruthenium catalyst. A procedure for thermal decomposition of noble metal acetylacetonates to deposit noble metal clusters on the surface of solid support was ...
Two Step Sintering of ZnTiO3 nanopowder
(International Institute for the Science of Sintering, Beograd, 2017)
Metastable nanopowder ZnTiO3 was pressed into cylindrical compacts at 200 MPa. Compacts were treated by conventional heating with isothermal holding at 931 degrees C for 10 minutes, 25 minutes and 40 minutes. ZnTiO3 compacts ...
Microstructure refinement and physical properties of Ag-SnO2 based contact materials prepared by high-energy ball milling
(International Institute for the Science of Sintering, Beograd, 2013)
High energy ball milling was used in order to improve dispersion of metal oxide in Ag-SnO2 electrical contact materials. The processed Ag-SnO2 (92:8) and Ag-SnO2In2O3 (87.8:9.30:2.9) powder mixtures were subsequently ...
Anisotropy Analysis of Low Cement Concrete by Ultrasonic Measurements and Image Analysis
(International Institute for the Science of Sintering, Beograd, 2016)
The analized material was high alumina low cement castable sintered at three different temperatures. Influence of initial material anisotropy on the thermal shock resistance as well as changes of anisotropy level during ...
The Bray-Liebhafsky oscillatory reaction: Kinetic investigations in reduction and oxidation pathways based on hydrogen peroxide concentration monitoring
(International Institute for the Science of Sintering, Beograd, 2000)
By direct monitoring of the hydrogen concentration during its catalytic decomposition into water and oxygen in the presence of potassium iodate and sulfuric acid, that is in the Bray-Liebhafsky system, the pseudo-rate ...

(International Institute for the Science of Sintering, Beograd, 2000)
The goal of these investigations was synthesis of optical fiber-magnetic powder composites with new application possibilities like sensors, detectors etc. Parts of results of the investigation of the possibility of embedding ...
The oscillatory Bray-Liebhafsky reaction as a matrix for analyzing enzyme and polymeric catalysts for hydrogen peroxide
(International Institute for the Science of Sintering, Beograd, 2001)
The Bray-Liebhafsky (BL) oscillatory reaction, as a reaction where hydrogen peroxide decomposes into the water and oxygen in the presence of iodate and hydrogen ions through a complex mechanism involving a number of ...
Modeling of coating optical fibers with polymer-magnetic powder composite coating
(International Institute for the Science of Sintering, Beograd, 2002)
A mathematical model of forming a composite coating on optical fiber was established. The model is based on existing mathematical models for coating optical fibers with polymer coating and experimentally defined rheological ...
Formation of Magnetic Microstructure of the Nanosized NiFe2O4 Synthesized Via Solid-State Reaction
(International Institute for the Science of Sintering, Beograd, 2012)
Magnetic NiFe2O4 structure formation was studied through structural, compositional and magnetic characterization of obtained reaction products of a simple, high yielding and low-cost solid-state reaction. Initial annealing ...
A comparative thermomagnetic study of melt-spun Nd-Fe-B alloys with different Nd content
(International Institute for the Science of Sintering, Beograd, 2009)
Changes in the phase composition and magnetic properties of three types of commercial Nd-Fe-B alloys with different Nd content - low (10-12 wt%), near stoichiometric (21-25 wt%) and rich (26-29 wt%) caused by thermomagnetic ...
