Determination of ionization constants (PKA) of β-hydroxy-β-arylalkanoic acids using high-pressure liquid chromatography
(University of Kragujevac, Faculty of Science, 2018)
pKa values of five β-hydroxy-β-arylalkanoic acids and ibuprofen were determined using the RP-HPLC method. Stationary phase was octadecyl modified (C-18) silica gel, and mobile phase was a mixture of methanol and one of ...
The particle size distribution (PSD) as criteria for comparison of silver powders obtained by different methods of synthesis and by conditions of electrolysis
(Bor : Technical Faculty, 2018)
Silver powders produced by both electrochemical (galvanostatic (DC) and potentiostatic (POT) regimes of electrolysis) and chemical processes were examined by scanning electron microscope, and particle size distribution ...
Electrochemical behaviour of sildenafil citrate at gold and cystein modified gold electrode in acid solution
(International Association of Physical Chemists (IAPC), 2018)
Electrochemical behavior of sildenafil citrate (SC) at gold and cystein (Cys) modified gold electrode (AulCys) in 0.1 M H2SO4 was investigated by cyclic voltammetry (CV) and by square wave voltammetry (SWV). Effect of scan ...
Cyclic Voltammetric Study of the Influence of Porosity on Electrochemical Response of Nickel-Alumina Modified Glassy Carbon Electrode
(International Institute for the Science of Sintering, Beograd, 2018)
Pure and nickel-modified alumina powders with different porosity were synthesized and applied on the glassy carbon electrode by means of Nafion polymer. The data obtained from the nitrogen adsorption-desorption isotherm ...
Cadmium specific proteomic responses of a highly resistant Pseudomonas aeruginosa san ai
(Royal Soc Chemistry, Cambridge, 2018)
Pseudomonas aeruginosa san ai is a promising candidate for bioremediation of cadmium pollution, as it resists a high concentration of up to 7.2 mM of cadmium. Leaving biomass of P. aeruginosa san ai exposed to cadmium has ...
Synthesis, Biological Evaluation and Docking Studies of Benzoxazoles Derived from Thymoquinone
(MDPI, 2018)
Thymoquinone (TQ), a natural compound with antimicrobial and antitumor activity, was used as the starting molecule for the preparation of 3-aminothymoquinone (ATQ) from which ten novel benzoxazole derivatives were prepared ...
Visible light absorption of TiO2 nanoparticles surface-modified with vitamin B-6: A comparative experimental and DFT study / Апсорпција наночестица TiO2 површински модификованих витамином B6 у видљивом делу спектра: упоредна експериментална и DFT студија
(Belgrade : Serbian Chemical Society, 2018)
Surface modification of titanium dioxide nanoparticles (TiO2 NPs) with the biologically active molecule pyridoxine hydrochloride (vitamin B-6) was found to alter the optical properties. Microstructural characterization ...

(Belgrade, Serbia : Engineering Society for Corrosion, 2018)
The paper presents the results of laser cleaning of corrosive and other deposits on a metal archaeological artefact from the Danube. Nd: YAG laser, energy up to 750 mJ and wavelengths λ = 1064 nm and 532 nm is used. The ...
Tailoring the corrosion resistance of Zn-Mn coating by electrodeposition from deep eutectic solvents / Poboljšanje korozione postojanosti Zn-Mn prevlake, elektrohemijskim taloženjem iz dubokih eutektičkih smeša
(Belgrade, Serbia : Engineering Society for Corrosion, 2018)
Well adhered, homogenous coatings were obtained from deep eutectic solvents (DES) based on choline chloride and urea, at current densities up to 20 mA cm-2. The coatings' morphology was analyzed by atomic force microscopy, ...
Improving stability of cerium oxide nanoparticles by microbial polysaccharides coating
(Serbian Chemical Soc, Belgrade, 2018)
Cerium oxide (CeO2) nanoparticles (CONPs) are interesting biomaterials with various applications in biomedicine, cosmetics and the pharmaceutical industry, but with limited practical application because of their low stability ...
