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 ...
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 ...
Peer-review process in journals dealing with chemistry and related subjects published in Serbia
(Association of the Chemical Engineers of Serbia, 2016)
A survey was conducted among editors of journals publishing in the field of chemistry, chemical technology and related topics in Serbia, aiming to collect information on their experience, problems and difficulties during ...
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 ...
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. ...
Liquid chromatography and liquid chromatography-mass spectrometry analysis of donepezil degradation products / Analiza degradacionih proizvoda donepezila primenom tečne hromatografije i tečne hromatografije-masene spektrometrije
(Association of the Chemical Engineers of Serbia, 2015)
This study describes the investigation of degradation products of donepezil (DP) using a stability-indicating RP-HPLC method for determination of donepezil, which is a centrally acting reversible acetyl cholinesterase ...
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 ...
