Voltammetric behavior of erythromycin ethylsuccinate at a renewable silver-amalgam film electrode and its determination in urine and in a pharmaceutical preparation
(Pergamon-Elsevier Science Ltd, Oxford, 2016)
Erythromycin, a macrolide antibiotic, has similar antimicrobial spectrum to penicillin and it is widely used, especially in the treatment of patients who are allergic to penicillin. In this work, the application of a ...
The influence of fly ash characteristics and reaction conditions on strength and structure of geopolymers
(Elsevier Sci Ltd, Oxford, 2015)
Reactivity of Class F fly ash (FA), development of strength, and structure of FA-based geopolymers, depending on the reaction conditions, were examined in this paper. The results of SEM/EDS and NMR analyses revealed that ...
Optimization of extraction of stinging nettle leaf phenolic compounds using response surface methodology
(Elsevier, Amsterdam, 2015)
A full three level factorial design was implemented for optimization of extraction parameters in order to maximize total phenolic (TP) yield from stinging nettle leaf. Factors considered were percentage of methanol in ...
Interactions of Molecules with cis and trans Double Bonds: A Theoretical Study of cis- and trans-2-Butene
(Wiley-VCH Verlag Gmbh, Weinheim, 2016)
Noncovalent interactions of cis- and trans-2-butene, as the smallest model systems of molecules with cis and trans double bonds, were studied to find potential differences in interactions of these molecules. The study was ...
Optimal pixel resolution for sand particles size and shape analysis
(Elsevier, Amsterdam, 2016)
In this paper, the influence of different scanning resolutions and the use of image analysis softwares for the image analysis, SigmaScan Pro, Image) and Matlab, on size and shape factors commonly used in particles ...
Lead immobilization by geopolymers based on mechanically activated fly ash
(Elsevier Sci Ltd, Oxford, 2014)
In this paper, the effectiveness of geopolymers based on initial and mechanically activated fly ash in immobilization of lead was investigated. Fly ash (FA) was firstly mechanically and then alkali activated at room ...
Discrimination between adsorption isotherm models based on nonlinear frequency response results
(Springer, Dordrecht, 2014)
A number of criteria are established for distinguishing between different adsorption isotherm types. These criteria are defined based on the adsorption isotherm derivatives up to the third order, which, on the other hand, ...
Silver film on nanocrystalline TiO2 support: Photocatalytic and antimicrobial ability
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
Nanocrystalline TiO2 films were prepared on glass slides by the dip coating technique using colloidal solutions consisting of 4.5 nm particles as a precursor. Photoirradiation of nanocrystalline TiO2 film modified with ...
Influences of synthesis methods and modifier addition on the properties of Ni-based catalysts supported on reticulated ceramic foams
(Springer, New York, 2014)
A method of synthesizing Ni-based catalysts supported on alpha-Al2O3-based foams was developed. The foams were impregnated with aqueous solutions of metal chlorides under an air atmosphere using an aerosol route. Separate ...
Densities, refractive indices and viscosities of the binary mixtures of dimethyl phthalate or dimethyl adipate with tetrahydrofuran
(Srpsko hemijsko društvo, Beograd, 2014)
Densities, refractive indices and viscosities of the binary mixtures of dimethyl phthalate (or dimethyl adipate) + tetrahydrofuran have been measured at eight temperatures (288.15 to 323.15 K) and atmospheric pressure. All ...
