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 ...
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 ...
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 ...
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 ...
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). ...
Determination of Degradation Level during Cavitation Erosion of Zircon Based Ceramic
(Belgrade : International Institute for the Science of Sintering, 2017)
Mechanical shock of zircon based ceramic induced by cavitation erosion testing was investigated in this study. Several parameters were followed in order to determine level of material degradation during the cavitation ...
