Investigation of forced and total degradation products of amlodipine besylate by liquid chromatography and liquid chromatography-mass spectrometry / Ispitivanje degradacionih proizvoda amlodipin-bezilata primenom tečne hromatografije i tečne hromatografije-masene spektrometrije u uslovima forsirane i potpune degradacije
(Association of the Chemical Engineers of Serbia, 2014)
An isocratic, reversed-phase liquid chromatographic method was applied for the investigation of the degradation products of amlodipine besylate under stressed conditions in solution. Amlodipine besylate stock solutions ...
Initial microbial degradation of polycyclic aromatic hydrocarbons
(Association of the Chemical Engineers of Serbia, 2016)
The group of polycyclic aromatic hydrocarbons (PAHs) are very hazardous environmental pollutants because of their mutagenic, carcinogenic and toxic effects on living systems. The aim of this study was to examine and compare ...
Electrochemical behavior of H3PW12O40/acid-activated bentonite powders / Elektorhemijsko ponašanje praha kiselo-aktiviranog bentonita modifikovanog H3PW12O40 kiselinom
(Association of the Chemical Engineers of Serbia, 2012)
Electrochemical behavior of 12-tungstophosphoric acid (HPW)/acid-activated bentonite (AAB) powders with various loadings of HPW was investigated. The physicochemical properties of the prepared powders were examined by X-ray ...
APPLICATION OF PELEG MODEL ON MASS TRANSFER KINETICS DURING OSMOTIC DEHYDRATATION OF PEAR CUBES IN SUCROSE SOLUTION
(Association of the Chemical Engineers of Serbia, 2015)
The applicability of Peleg model was investigated for predicting mass transfer kinetics during the osmotic dehydration (OD) process of pears, at different concentrations (40, 60 and 70%, w/w) and temperatures (20, 35 and ...
The influence of extraction parameters on physicochemical properties of special grain brandies with ganoderma lucidum
(Assoc Chemical Eng, Belgrade, 2016)
Ganoderma lucidum is one of the five major medicinal mushrooms. In Asian countries, alcoholic beverages with Ganoderma are traditionally produced and sold in local markets as a symbol of healthy products. The aim of this ...
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 ...
Experimental investigation of heat transfer in three-phase fluidized bed cooling column
(Association of the Chemical Engineers of Serbia, 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 ...
Friction factor for water flow through packed beds of spherical and non-spherical particles
(Association of the Chemical Engineers of Serbia, 2017)
The aim of this work was the experimental evaluation of different friction factor correlations for water flow through packed beds of spherical and non-spherical particles at ambient temperature. The experiments were performed ...
Stress corrosion cracking resistance of aluminum alloy 7000 series after two-step aging / Otpornost aluminijumske legure serije 7000 prema naponskoj koroziji posle dvostepenog termičkog taloženja
(Association of the Chemical Engineers of Serbia, 2015)
The effect of one-step and a new (short) two-step aging process on the resistance to stress corrosion cracking of an aluminum alloy 7000 series was investigated, using slow strain rate test and fracture mechanics method. ...
