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 ...
Gas-solid and gas-liquid mass transfer: Effect of turbulent Schmidt number
(Association of the Chemical Engineers of Serbia, 2007)
The scope of this paper is to explain effect of eddy viscosity and turbulent Schmidt number on mass transfer rate. New, theoretically based correlation for gas-liquid mass transfer coefficients are proposed.
Immobilization of fish chromatophores for use as a micro-biosensor for biological toxins / Imobilizacija hromatofora riba radi korišćenja kao biosenzor za biološke toksine
(Association of the Chemical Engineers of Serbia, 2003)
Chromatophores isolated from the Siamese fighting fish, Betta splendens, represent a class of living cells that provide a vivid color response to microbial pathogens and environmental toxins. The selection of the most ...
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 ...
