A study of the catalytic role of a gold electrode in the electrochemical activation of four macrolide antibiotics in sodium bicarbonate solution / Ispitivanje katalitičke uloge elektrode od zlata u elektrohemijskoj aktivaciji četiri makrolidna antibiotika u natrijum-bikarbonatnom elektrolitu
(Association of the Chemical Engineers of Serbia, 2010)
Using the cyclic voltammetry, it has been shown that hydrogen evolution at a gold electrode is necessary in the electrochemical activation of azithromycin dihydrate and erythromycin A. After four hours of the potential ...
Antimicrobial textile prepared by silver deposition on dielectric barrier discharge treated cotton/polyester fabric
(Association of the Chemical Engineers of Serbia, 2008)
The objective of this research was to impart the additional value on cotton/polyester (Co/PES) fabrics (i.e. antimicrobial properties) to improve the quality of life and thus to tap new markets with the product. In this ...
Substituent effect on IR, 1H- and 13C-NMR spectral data in N-substituted phenyl)-2-cyanoacetamides: A correlation study / Uticaj supstituenata na IR, 1H- i 13C-NMR spektralne podatke N-(supstituisanih fenil)-2-cijanoacetamida - korelaciona analiza
(Association of the Chemical Engineers of Serbia, 2013)
Linear free energy relationships (LFER) were applied to the IR, 1H- and 13C- -NMR spectral data of N-(substituted phenyl)-2-cyanoacetamides. A variety of substituents were employed for phenyl substitution and fairly good ...
Synthesis of tetraalkylthiuram disulfides using different oxidants in recycling solvent mixture / Sinteza tetraalkiltiuram-disulfida primenom različitih oksidacionih sredstava u reciklovanoj smeši rastvarača
(Association of the Chemical Engineers of Serbia, 2012)
A new optimized laboratory synthesis of tetraalkylthiuram disulfides, starting from dialkyl amines and carbon disulfide in presence of three oxidants (hydrogen peroxide, potassium peroxodisulfate and sodium hypochlorite) ...
The effects of solvents and structure on the electronic absorption spectra of the isomeric pyridine carboxylic acid N-oxides / Uticaj rastvarača i strukture na elektronske absorpcione spektre izomernih piridin-karboksilnih kiselina N-oksida
(Association of the Chemical Engineers of Serbia, 2013)
The ultraviolet absorption spectra of the carboxyl group of three isomeric pyridine carboxylic acids N-oxides (picolinic acid N-oxide, nicotinic acid N-oxide and isonicotinic acid N-oxide) were determined in fourteen ...
Lipophilicity assessment of some 5,5-disubstituted hydantoins by the means of reversed phase liquid chromatography / Procena lipofilnosti nekih 5,5-disupstituisanih hidantoina primenom tečne hromatografije na obrnutim fazama
(Association of the Chemical Engineers of Serbia, 2013)
The retention of some 5,5-disubstituted hydantoins was investigated by reversed phase high performance thin-layer chromatography (RP HPTLC) and reversed phase high-pressure liquid chromatography (RP HPLC). The mobile phases ...
Ship waste quantities prediction model for the Port of Belgrade / Model za predviđanje količine otpada u Luci Beograd
(Association of the Chemical Engineers of Serbia, 2011)
This study focuses on the issues related to the waste management in river ports in general and especially in the port of Belgrade. Data on solid waste, waste oils, oily waters, gray water and black water have been collected ...
Experimental investigation of heat transfer in three-phase fluidized bed cooling column
(Savez hemijskih inženjera, Beograd, 2015)
A three-phase (gas-liquid-solid) fluidized bed was used to study the heat transfer characteristics of a system consisting of low-density (290 kg/m(3)) spherical particles (2 cm diameter) in a 0.25 m cylindrical column with ...
The possibility of lactic acid fermentation in the Triticale stillage / Mogućnost mlečno-kiselinske fermentacije na džibri tritikalea
(Association of the Chemical Engineers of Serbia, 2011)
Triticale stillage is a by-product of bioethanol production. A research study was conducted in order to see if triticale stillage is adequate for lactic acid bacteria growth and lactic acid fermentation. Three Lactobacillus ...
Effect of temperature on the physical changes and drying kinetics in plum (Prunus domestica L.) Požegača variety / Uticaj temperature na fizičke promene i kinetiku sušenja šljive (Prunus domestica L.) sorte požegača
(Association of the Chemical Engineers of Serbia, 2011)
In this study, drying kinetics of autochthonous variety Požegača plum was examined in a laboratory dryer at three temperatures. The whole plum fruits, together with the kernels were subjected to the drying process. The ...
