Study on the efficient removal of clopyralid from water using a resorcinol-formaldehyde carbon cryogel
(Srpsko hemijsko društvo, Beograd, 2014)
A resorcinol-formaldehyde carbon cryogel was prepared, characterized and used for the removal of the commonly used herbicide clopyralid from aqueous solutions under varying experimental conditions. The carbon exhibited a ...
Corrosion properties of an aluminium alloy 7000 series after a new two step precipitation hardening / Otpornost prema koroziji aluminijumske legure serije 7000 posle novog dvostepenog termičkog taloženja
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
Corrosion properties of an aluminium alloy 7000 series were investigated by different electrochemical methods. The alloy was subjected to the one-step and to a new two-step precipitation hardening. Polarization measurements ...
Polyethersulfone membranes with integrated adsorbent particles for heavy metals capture
(Belgrade, Serbia : Society of Physical Chemists of Serbia, 2014)
Novel polyethersulfone membranes with integrated submicron adsorbent particles were prepared by combining photoirradiation with liquid phase inversion. These particles consist of cross-linked poly(glycidyl methacrylate-c ...
Economizer water-wall damages initiated by feedwater impurities
(Savez hemijskih inženjera, Beograd, 2014)
The main causes of efficiency loss in thermal power plants are boiler tube failures that diminish unit reliability and availability, and raise the cost of the electric energy. For that reason, the regular examination of ...
Finite element modelling of creep process - steady state stresses and strains
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Finite element modelling of steady state creep process has been described. Using an analogy of visco-plastic problem with a described procedure, the finite element method has been used to calculate steady state stresses ...
Chemometric Approach in Studying of the Retention Behavior and Lipophilicity of Potentially Biologically Active N-Substituted-2-phenylacetamide Derivatives
(Soc Brasileira Quimica, Sao Paulo, 2014)
The potential biological activity of a molecule largely depends on its lipophilicity. The lipophilicity of derivatives of N-substituted-2-phenylacetamide was investigated experimentally, by applying thin-layer chromatography ...
The effect of the size and shape of alumina nanofillers on the mechanical behavior of PMMA matrix composites
(Srpsko hemijsko društvo, Beograd, 2014)
Composites with the addition of alumina nanofillers show improvement in mechanical properties.Poly(methyl methacrylate), PMMA, was used as a matrix and two different types of nanofillers having extremely different shapes ...
Modelling and optimization of surfactant sensor response characteristics for the use in surface water and wastewater analysis / Modelovanje i optimizovanje održivih karakteristika tenzidnog senzora za korišćenje pri analizi površinskih i otpadnih voda
(Engineering Society for Corrosion, Belgrade, Serbia, 2014)
The theoretical model of potentiometric titration curves of sodium dodecyl sulfate (anionic surfactant) was proposed and the response parameters of two surfactant sensors (commercial and self-made) were investigated. The ...
Laser cleaning of textile artifacts with metal threads: Process parameter optimization / Lasersko čišćenje tekstilnih eksponata sa korodiranim metalnim nitima - optimzacije parametara procesa
(Military Technical Institute, Belgrade, 2014)
This paper presents the results of the laser cleaning effects on textile samples with corroded metallic threads. In many museum collections, there are textile exhibits like uniforms, national costumes, flags and home ...
Determination of kinetic parameters for complex transesterification reaction by standard optimisation methods / Određivanje kinetičkih parametara složene reakcije transesterifikacije primenom standardnih optimizacionih metoda
(Association of Chemical Engineers of Serbia, 2014)
This paper represents a methodology for kinetic parameter estimation based on standard optimization methods. The parameter estimation procedure is applied to the example of modelling of non-catalytic transesterification ...
