Impact of Alumina Particles on the Morphology and Mechanics of Hybrid Wood Plastic Composite Materials
(Belgrade : Association for ETRAN Society, 2019)
Hybrid composite panels of Wood-Plastic Composites (WPC) consisting of wood and
poly (methyl methacrylate) (PMMA) were reinforced with alumina particles and made by
“hot pressing” method. Alumina-based particles were ...
Kinetics of the Bray-Liebhafsky oscillatory reaction perturbed by polymer supported cobalt catalyst
(International Institute for the Science of Sintering, Beograd, 2011)
The Bray-Liebhafsky (BL) oscillatory reaction generated in the batch reactor at 62- 68 oC was perturbed by cobalt(II)-nitrate, supported on the macroreticular copolymer of poly-4-vinylpyridine with divinylbenzene (Co-PVPDVB). ...
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 ...
The Effect of Sintering Temperature on Mesoporous Structure of WO3 Doped Tio(2) Powders
(International Institute for the Science of Sintering, Beograd, 2018)
In this study, WO3 doped TiO2 powders were synthesized via sol-gel method combined with a hydrothermal process. The effect of sintering temperature on mesoporous structure and catalytic activities of these powders were ...
The effect of ageing on YBa2Cu3O7-x obtained by the photoacoustic method
(Belgrade: International Institute for the Science of Sintering, 2003)
Thermal diffusivity and electric transport properties of fourteen years old superconducting YBa2Cu3O7-x pellets were obtained using the photoacoustic transmission technique and then compared with freshly made superconducting ...
Characterisation of dispersive systems using a coherer
(Belgrade : International Institute for the Science of Sintering, 2002)
The possibility of characterization of aluminium powders using a horizontal coherer has been considered. Al powders of known dimension were treated with a high frequency electromagnetic field or with a DC electric field, ...
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 ...
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 influence of strontium content and sintering temperature on monazite stability
(Association for ETRAN Society, 2024)
This paper shows a simple way to synthesize a series of Ce1-xSrxPO4 ceramic materials using acetate solutions of Ce and Sr instead of nitrate which were used so far. For synthesis, the preparation method was used by simple ...
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 ...
