Microwave-assisted synthesis of 2-pyridone and 2-pyridone-based compounds / Mikrotalasna tehnika u sintezi 2-piridona i jedinjenja na bazi 2-piridona
(Association of Chemical Engineers of Serbia, 2014)
2-Pyridones are important heterocyclic compounds that are widely used in medical chemistry, and their various derivatives have significant biological and medical applications. In this paper, the synthesis of 2-pyridones ...
Optimization of extraction of antioxidant components from yarrow herb / Optimizacija ekstrakcije antioksidantnih komponenata iz herbe hajdučke trave
(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 ...
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 ...
Synthesis of fluorine substituted hydroxyapatite nanopowders and application of the central composite design for determination of its antimicrobial effects
(Elsevier Science Bv, Amsterdam, 2014)
Synthetic biomaterials based on fluorine substituted hydroxyapatite are potentially attractive for orthopedic and dental implant applications. The new synthesis of fluorine substituted hydroxyapatite samples were done by ...
Electrochemical characterization and determination of carbamazepine as pharmaceutical standard and tablet content on gold electrode / Elektrohemijsko karakterisanje i određivanje karbamazepina kao farmaceutskog standarda i sadržaja tablete na elektrodi od zlata
(Association of Chemical Engineers of Serbia, 2014)
The anodic behaviour of carbamazepine (CBZ), an anticonvulsant drug, has been studied on gold electrode in 0.1 mol dm-3 phosphate buffer of pH 7.0 by using cyclic voltammetry. It has been found that the value of the oxidative ...
Surrounding gate long channel nanowire MOSFET modelling-extended analysis
(IOP Publishing Ltd, Bristol, 2014)
Based on the approximate solution of Poisson's equation in the case of a p-doped silicon body, an improved current-voltage characteristic model of long-channel cylindrical surrounding-gate Si nanowire MOSFET is proposed. ...
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 ...
Copper nanoparticles with high antimicrobial activity
(Elsevier Science Bv, Amsterdam, 2014)
Copper (Cu) hydrosol containing small nanoparticles (NPs) (similar to 5 nm) with narrow size distribution were used to investigate antimicrobial activity toward representative microorganisms of public concern (Escherichia ...
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 ...
