Analysis of refractory castables subjected to thermal shock by non-destructive methods
(Bor : University of Belgrade - Technical Faculty in Bor, 2014)
The purpose was to investigate behavior and degradation level of synthesized alumina based low cement castable sintered at different temperatures during the thermal stability testing. Behavior of the refractory concrete ...
Assessment of sulfur-polymer composite quality based on nondestructive testing
(Bor : University of Belgrade - Technical Faculty in Bor, 2014)
In order to assess quality of sulfur-polymer composite, the samples were subjected to the induced destruction using hydrochloric acid solution. The image analysis technique was used for surface destruction monitoring. The ...
Oxygen Reduction on Palladium Modified Zeolite 13X
(Serbian Ceramic Society, 2014)
Palladium was dispersed over zeolite NaX by procedure of impregnation/thermal degradation of palladium acetylacetonate salt.
Samples characterization was performed by X-ray diffraction and SEM analysis. XR D analysis ...
Analysis of acoustic cloaks for anti-sonar camouflage based on local resonance in acoustic metamaterials
(Belgrade : The Military Technical Institute, 2014)
Non-visual camouflage plays a significant role in the art of military deception. One of the fields of interest is auditory camouflage, where the goal is to remove the acoustic signature of an object, whether it is generated ...
Electrochemical behavior of acid activated clays
(Belgrade : Vinča Institute of Nuclear Sciences, 2014)
Smectites are phyllosilicates of 2:1 type, meaning that octahedral sheet in sandwiched between two tetrahedral sheets. Due to isomorphous substitutions (Al3+ or Fe3+ for tetrahedral Si4+ and Mg2+, Fe2+ or Fe3+ for octahedral ...

Electrochemical oxidation of formic acid on Pt- and Pd-based bimetallic catalysts
(Society of Physical Chemists of Serbia, 2014)
Electrochemical oxidation of HCOOH was studied on single metal Pt, Pt/C and Pd black catalysts, on bimetallic surfaces of Pt-Au and Pd-Au bulk electrodes as well as on Pt-Co/C, Pt-Au/C and Pt-Pd nanocatalysts. The ...
The Influence of the Nickel Incorporation Method on the Performance of Bentonite Based Electrodes in Electrooxidation of Phenol
(Serbian Ceramic Society, 2014)
The beneficial interrelationship between Ni i Fe as active site for electrooxidation of phenol was investigated. Four Ni,Fe-bentonite samples were synthesized by different methods. First two samples were obtained by ...
Dynamic adsorption of Rhodamine B from dilute aqueous solutions using negatively-charged membrane adsorbers
(Belgrade : Institute of Technical Sciences of SASA, 2014)
A series of polyethersulfone membranes with integrated cross-linked poly(glycidyl methacrylate-co-2-acrylamido-2-methylpropane sulfonic acid) were synthesized using a combination of the traditional immersion precipitation ...
Thermoplastic polyurethanes based on poly(dimethylsiloxane): structure and thermal behavior
(Belgrade : Society of Physical Chemists of Serbia, 2014)
Segmented polyurethanes are an important class of thermoplastic elastomers
which have potential use as a biomaterial. Biostability, biocompatibility and
some other features of polyurethanes can be improved by the ...
