Surface characterization of polymers by inverse gas chromatography
(Journal of the Serbian Chemical Society, 2007)
An inverse gas chromatographic (IGC) study of the sorption properties of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), PGME, and PGME modified with ethylene diamine, PGME-en, was ...
Influence of sodium dodecyl sulfate on the reaction between Nile Blue A and hydrogen peroxide
(Journal of the Serbian Chemical Society, 1999)
The influence of the anionic surfactant sodium dodecyl sulfate on the rate of the reaction between the cationic form of Nile Blue A and hydrogen peroxide was investigated in the pH range from 5 to 8.5. A retardation of the ...
Correlation between morphology and magnetic properties of electrochemically produced cobalt powder particles
(Journal of the Serbian Chemical Society, 2015)
Cobalt 3D powder particles were successfully prepared by galvanostatic electrodeposition. The electrodeposited cobalt powders were characterized by X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM), ...
Influence of the radioactive concentration of the in vitro stability of Tc-99m(Sn)-pyrophosphate
(Journal of the Serbian Chemical Society, 1999)
The in vitro stability of Tc-99m(Sn)-pyrophosphate solution was examined in dependence on the preparation conditions of the samples, the radioactive concentration of Tc-99m in the kit and the time elapsed after labeling. ...
Redox properties of alkyl-substituted 4-aryl-2,4-dioxobutanoic acids
(Journal of the Serbian Chemical Society, 2017)
Redox properties of a set of aryldiketo acids (ADKs), small organic molecules that comprise 2,4-dioxobutanoic acid moiety, were studied. Along with well-known HIV-1 integrase (IN) inhibition, ADKs exert widespread biological ...
Spectroscopic investigation of two Serbian icons painted on canvas
(Journal of the Serbian Chemical Society, 2015)
A multianalytical study of two Serbian icons, The Virgin and Child and St. Petka, painted on canvas by unknown authors was performed in order to identify the materials used as pigments, binders and the ground layer. The ...
Physicochemical characterisation of pottery from the Vinca culture, Serbia, regarding the firing temperature and decoration techniques
(Journal of the Serbian Chemical Society, 2016)
A study of decorated Neolithic pottery samples from the excavation site Plocnik, Serbia, was performed using X-ray powder diffraction (XRPD), Fourier transform infrared (FTIR) and X-ray fluorescence (XRF) spectroscopy. The ...
Interpretative optimization of the isocratic ion chromatographic separation of anions
(Journal of the Serbian Chemical Society, 2016)
Interpretive retention modeling was utilized to optimize the isocratic ion chromatographic (IC) separation of the nine anions (formate, fluoride, chloride, nitrite, bromide, nitrate, phosphate, sulfate and oxalate). The ...
Inverse gas chromatography of chromia. Part II. Finite surface coverage
(Journal of the Serbian Chemical Society, 2002)
The interactions of n-hexane, benzene, chloroform, and tetrahydrofuran with dried (amorphous) chromia (I) and chromia heated at 1073 K (crystalline) (II), both obtained from a colloidal dispersion, and a commercially ...
Sol-gel derived silicon nitride powders
(Journal of the Serbian Chemical Society, 1999)
The sol-gel synthesis of silicon nitride powders has been studied. The precursor gels were prepared from a colloidal dispersion of silicon dioxide and sucrose, with mole ratios of reactants, C/SiO2, ranging from 2 to 4. ...
