Thermal diffusivity of single crystal Bi0.9Sb0.1
(International Institute for the Science of Sintering, Beograd, 2010)
A single crystal Bi0.9Sb0.1 ingot was synthesized using the Bridgman technique. Thermal diffusivity and electronic transport properties of single crystal cleaved plates (00l) were determined from PA photoacoustic phase and ...
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 ...
Synthesis of Highly Porous Al2O3-YAG Composite Ceramics
(International Institute for the Science of Sintering, Beograd, 2016)
Al2O3-YAG composite was obtained by sintering of porous Al2O3 preforms infiltrated with water solution of aluminium nitrate nonahydrate, Al(NO3)(3)center dot 9H(2)O and yttrium nitrate hexahydrate, Y(NO3)(3)center dot ...
ZnTiO3 ceramic nanopowder microstructure changes during compaction
(International Institute for the Science of Sintering, Beograd, 2013)
ZnTiO3 nanopowder as a constitutive component in compact production was primarily characterized. Scanning electron micrographs of as received powder were recorded. Mercury porosimetry and nitrogen adsorption were also ...
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 ...
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 ...
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 ...
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 ...
Electrochemical and structural properties of Ni(II)-alumina composites as an annealing temperature function
(International Institute for the Science of Sintering, Beograd, 2019)
Alumina powders, pure and doped with nickel, were synthetized by sol-gel method and calcined at 500, 900 and 1100°C in order to obtain mesoporous structures with a high specific surface area, well adapTab. to catalytic ...
