(Association of Chemical Engineers of Serbia, 2014)
Recently, research efforts have been directed toward medicinal plants and their extracts, as important sources of natural antioxidant. Lots of biologically active compounds are responsible for the antioxidant effects of ...
Electrospinning of the laser dye rhodamine B-doped poly(methyl methacrylate) nanofibers
(Srpsko hemijsko društvo, Beograd, 2014)
The electrospinning of rhodamine B (RhB)-doped poly(methyl methacrylate) (PMMA) is presented as a promising technique for processing photoluminescent nanofibers. Nanofibers with concentrations of RhB in PMMA between 0.05 ...
Novel support for enzyme immobilization prepared by chemical activation with cysteine and glutaraldehyde
(Elsevier, Amsterdam, 2014)
Immobilization of enzymes on glutaraldehyde-activated supports has been largely used on supports previously activated with amine groups. Therefore, the supports are positively charged hence usually the immobilization is ...
The application of NIR spectroscopy with chemometric analysis for monitoring a powder blending process
(Srpsko hemijsko društvo, Beograd, 2014)
This paper reports the use of near infrared (NIR) spectroscopy as a process analytical technology (PAT) tool for monitoring the metformin (N,N-dimethylimidodicarbonimidic diamide) hydrochloride and poly(vinyl pyrrolidone) ...
Assessment of the impact of geographical factors on the spatial distribution of heavy metals in soils around the steel production facility in Smederevo (Serbia)
(Elsevier Sci Ltd, Oxford, 2014)
The concentration of heavy metals (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn) in surface soils in the area surrounding the steel production facility in Serbia was determined to assess the contribution of emissions to pollution. ...
Influence of sintering temperature on thermal shock behavior of low cement high alumina refractory concrete
(Elsevier Sci Ltd, Oxford, 2014)
The purpose of this study was to investigate behavior and degradation level of refractory concrete sintered at different temperatures during the thermal stability testing. Alumina based low cement castable was synthesized, ...
Determination of thermodynamic interactions of polylactide and biphasic calcium phosphate/polylactidecomposite by inverse gas chromatography at infinite dilution
(Springer, New York, 2014)
Inverse gas chromatography at infinite dilution was applied to determine the thermodynamic interactions of poly(l-lactide) (PLLA) and the composite of biphasic calcium phosphate and PLLA (BCP/PLLA). The specific retention ...
Aqueous nicotine solutions: pH-measurements and salting-out effects - Analysis of the effective Gibbs energies of hydration and ionic strengths of the solutions
(Srpsko hemijsko društvo, Beograd, 2014)
This work is a continuation of previous studies on phase demixing - salting-out effects in aqueous nicotine solutions. Thus, pH measurements were performed, allowing a brief analysis of the existing hydrogen bond interactions. ...
Solid circulation rate and particle collisions in quasi two-dimensional water fluidized beds of spherical particles
(Elsevier Science Bv, Amsterdam, 2014)
The equations for the overall particle circulation rate and the frequency of particle-particle collisions in the quasi two-dimenional water-fluidized bed were proposed. The equations were based on the experimental results ...
