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 ...
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). ...
Structure and Properties of Nanocrystalline Tetragonal BaTiO3 Prepared by Combustion Solid State Synthesis
(International Institute for the Science of Sintering, 2020)
Barium titanate (BaTiO3) attracts high scientific and technological attention due to good dielectric and electromechanical properties. Although BaTiO3 is one of the most frequently investigated ferroelectric materials, the ...
Multiferroic Heterostructure BaTiO3/ε-Fe2O3 Composite Obtained by in situ Reaction
(Belgrade : International Institute for the Science of Sintering, 2021)
Solid-state reaction between BaTiO3 and Fe2O3 was used to produce a multiferroic heterostructure composite. Commercial BaTiO3 and Fe(NO3)3•9H2O were suspended in ethanol for 30 minutes in an ultrasound bath. The prepared ...
Effect of Sintering Temperature and Calcium amount on Compressive Strength of Brushite-Metakaolin Polymer Materials
(Association for ETRAN Society, 2022)
The effect of Ca2+ amount and sintering temperature on mechanical properties of geopolymer-brushite (GPB) binders was investigated. Brushite and raw abandoned kaolinite clay thermally transformed into metakaolin were used ...
Characterization of cobalt ferrite nanoparticles obtained by various synthesis methods and comparison with the Raman spectra of other ferrites and some cubic oxide spinels / Kарактеризација наночестица кобалт ферита добијених различитим методама синтезе и поређење са Рамановим спектрима других ферита и неких кубичних оксидних спинела
(Association for ETRAN Society, 2023)
ingle phase cobalt ferrite (CoFe2O4) with nanoparticles of similar sizes (15.7-19 nm) was obtained by different synthesis methods: coprecipitation, ultrasonically assisted coprecipitation, coprecipitation followed by ...
The influence of strontium content and sintering temperature on monazite stability
(Association for ETRAN Society, 2023)
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 ...
Fourier-transform infrared spectroscopy analysis of mechanochemical transformation kinetics of sodium carbonate to bicarbonate
(ETRAN Society, 2022)
During mechanical activation, qualitative changes that can produce various phenomena occur in the material. In this study, anhydrous sodium carbonate was mechanically activated for 2, 7, 14, and 28 minutes in a vibro mill ...
One-Pot Combustion Synthesis of Nickel Oxide and Hematite: from Simple Coordination Compounds to High Purity Metal Oxide Nanoparticles
(Belgrade : International Institute for the Science of Sintering, 2020)
This work is the first report of a very simple and fast one-pot synthesis of nickel oxide (NiO) and hematite (α-Fe2O3) nanoparticles by thermal decomposition of transition metal aqua complexes with camphor sulfonate anions. ...
Preparation and Characterization of Novel Glycidyl Methacrylate/Clay Nanocomposites
(Serbia : International Institute for the Science of Sintering (IISS), 2022)
The impact of the type and amounts of nanofiller on the features of the glycidyl methacrylate-co-ethylene glycol dimethacrylate (GMA-co-EGDMA)/organomodified montmorillonite (OMt) nanocomposites that were prepared by in ...
