Influence of annealing temperature on sensitisation behaviour and corrosion properties of an Al-6.8wt% Mg alloy
(Wiley-VCH Verlag Gmbh, Weinheim, 2016)
Influence of annealing temperature on beta-(Al3Mg2) phase precipitation and corrosion properties of sensitised Al-6.8wt% Mg alloy is investigated. Sensitisation of specimens annealed at 320 degrees C results in IGC and SCC ...
Photo-assisted electrochemical oxidation of the urea onto TiO2-nanotubes modified by hematite
(Elsevier Science Bv, Amsterdam, 2017)
The electrochemical oxidation of the urea in near neutral pH is investigated on platinum electrode. It is shown that oxidation reaction is practically inhibited up to the potentials of similar to 0.9 V. The same reaction ...
Characterization of MgAl2O4 Sintered Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
Single phase MgAl2O4 was made from a one-to-one molar ratio of MgO and Al2O3 powders mixed using ball-milling. Mixtures of MgO and Al2O3 were subsequently treated in planetary ball mill for 30, 60, 90 and 120 minutes in ...
Cavitation damages morphology of high-strength low-alloy steel
(Croatian Metallurgical Soc, Zagreb, 2016)
This paper presents the research into behaviour of HSLA steel affected by cavitation. The parent material (PM) and simulated heat-affected zone (SHAZ) were studied. Ultrasonic vibratory cavitation test was performed in ...
The Thermophysical Properties of Primary Phase in Lithium Germanium Phosphate Glass
(Science of Sintering, 2021)
The selected lithium germanium-phosphate glass was prepared by a conventional melt-quenching technique. The XRD method was employed to confirm the glass was obtained and to reveal crystalline phases during heat treatment. ...
Characterization and Morphology of Copper Powder Particles as a Function of Different Electrolytic Regimes
(Esg, Belgrade, 2010)
The effect different deposition regimes (constant and reversing currents), on the powdered copper electrodeposits morphology were investigated. The results obtained in constant regimes were compared with those obtained in ...
An investigation of tebuconazole degradation using a gold electrode
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2016)
Tebuconazole, a pesticide that presents risks for ecosystems, groundwater and human health, was degraded on a gold electrode as the catalyst in 0.05 M NaHCO3 using cyclic voltammetry (CV). First, tebuconazole was characterized ...
CO2 Conversion Enhancement in a Periodically Operated Sabatier Reactor: Nonlinear Frequency Response Analysis and Simulation-based Study
(Wiley-VCH Verlag Gmbh, Weinheim, 2018)
Conversion of CO2 into synthetic CH4 via thermocatalytic hydrogenation (the Sabatier reaction), has recently gained increasing interest as a possible route for CO2 utilization and energy storage pathway. Herein, we analyze ...

(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
This paper presents method for sustainability assessment of thermal power plant unit using multi-criteria analysis with aim to create base for business decision. Seven options of possible status of thermal power plant ...
The crystallisation of calcium phosphate glass containing vanadium oxide
(University of Chemistry and Technology, Prague, 2007)
The crystallisation behaviour of calcium phosphate glass containing vanadium oxide was studied. Glass with a molar ratio of [CaO]/[P2O5] = 1.13 and a V2O5 content of 8 mol.% was prepared for the experiments. The crystallisation ...
