Friction factor for water flow through packed beds of spherical and non-spherical particles
(Savez hemijskih inženjera, Beograd, 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 ...

(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) ...
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 ...
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 ...
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 ...
Hydrodistillation kinetics and essential oil composition from fermented parsley seeds / Kinetika hidrodestilacije i sastav etarskog ulja fermentiranog semena peršuna
(Association of the Chemical Engineers of Serbia, 2005)
The effect of fermentation conditions on the yield and composition of the essential oil from Petroselinum crispum (Mill.) Nym. ex. A.W. Hill seeds was studied. The yield of essential oil was determined by a Clevenger-type ...
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 ...
