Ecologically Friendly Chitosan-montmorillonite Bio-nanocomposite as Adsorbent for Textile Dyes from Aqueous Solutions
(International Institute for the Science of Sintering, Beograd, 2017)
The bio-nanocomposite of montmorillonite and natural biopolymer chitosan (C-MM) was synthesized. Intercalation of chitosan in form of monolayer into the interlamellar space of montmorillonite was confirmed by XRD and IR ...
Cyclic Voltammetric Study of the Influence of Porosity on Electrochemical Response of Nickel-Alumina Modified Glassy Carbon Electrode
(International Institute for the Science of Sintering, Beograd, 2018)
Pure and nickel-modified alumina powders with different porosity were synthesized and applied on the glassy carbon electrode by means of Nafion polymer. The data obtained from the nitrogen adsorption-desorption isotherm ...
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 ...
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 ...
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 ...
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 ...
State of the Art and Challenges in Development of Electrical Contact Materials in the Light of the RoHS Directive
(International Institute for the Science of Sintering, Beograd, 2012)
The article surveys current state of the art and challenges in the development of the electrical contact materials in the light of the EU Directive on Restriction of Hazardous Substances (RoHS). The focus was placed on ...
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). ...
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 ...
