Physical-mechanical and microstructural properties of alkali-activated fly ash-blast furnace slag blends
(Elsevier Sci Ltd, Oxford, 2015)
This paper investigated physical mechanical and microstructural properties of alkali-activated binders based on blends of fly ash (FA) and blast furnace slag (BFS). FA BFS blends were alkali-activated with sodium silicate ...
The effect of grain size on the biocompatibility, cell-materials interface, and mechanical properties of microwave-sintered bioceramics
(Wiley, Hoboken, 2012)
The effect of decreasing the grain size on the biocompatibility, cellmaterial interface, and mechanical properties of microwave-sintered monophase hydroxyapatite bioceramics was investigated in this study. A nanosized ...
Effect of CO2 pre-treatment on scCO(2) extraction of natural material
(Elsevier Science Sa, Lausanne, 2012)
Pre-treatment of natural materials prior to their extraction strongly influences the efficiency of the process. Therefore, proper selection of pre-treatment method enables intensification of extraction process. Within this ...
Efficiency of sepiolite in broilers diet as uranium adsorbent
(Springer, New York, 2015)
The use of phosphate mineral products in animal nutrition, as a major source of phosphor and calcium, can lead to uranium entering the food chain. The aim of the present study was to determine the protective effect of ...
Copper-Sulfate Pentahydrate as a Product of the Waste Sulfuric Acid Solution Treatment
(Springer, New York, 2012)
The aim of this study is synthesis of copper-sulfate pentahydrate from the waste sulfuric acid solution-mother liquor generated during the regeneration process of copper bleed solution. Copper is removed from the mother ...
Effect of chemisorbed carbon monoxide on Pt/C electrode on the mechanism of the hydrogen oxidation reaction
(Elsevier, 2009)
The influence of poisoning of Pt catalyst by CO on the kinetics and mechanism of H2 oxidation reaction (HOR) at Pt/C electrode in 0.5 mol dm-3 HClO4, saturated with H2 containing 100 ppm CO, was examined with rotating disc ...
Surfactant-modified clinoptilolite as a salicylate carrier, salicylate kinetic release and its antibacterial activity
(Elsevier Science Bv, Amsterdam, 2012)
The cationic surfactant benzalkonium chloride (BC) was used for modification of the natural clinoptilolite surface in order to prepare a suitable carrier for the salicylate anion. The salicylate-containing clinoptilolite ...
Novel kinetic model of the removal of divalent heavy metal ions from aqueous solutions by natural clinoptilolite
(Elsevier, Amsterdam, 2012)
Removal of heavy metal ions from aqueous solutions using zeolites is widely described by pseudo-second order kinetics although this model may not be valid under all conditions. In this work, we have extended approaches ...
Pharmaceutical residues in the Danube River Basin in Serbia - a two-year survey
(Iwa Publishing, London, 2012)
Pharmaceuticals are emerging contaminants with damaging effects to the environment and human health. Their presence in surface and especially groundwaters is regarded as detrimental, as they can ultimately reach drinking ...
The impact of air pollution from the mining-metallurgical complex on the content of total sulfur in plant material and soil
(Air Quality: Environmental Indicators, Monitoring and Health Implications, 2013)
The area of Bor and the surroundings (Eastern Serbia) have beenknown for exploitation and processing of sulfide copper ores for morethan a hundred years. Long-term ore exploitation in the examined areahas made a great ...
