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 ...
Electrophoretically deposited nanosized hydroxyapatite coatings on 316LVM stainless steel for orthopaedic implants / Elektroforetsko taloženje prevlaka hidroksiapatitnog nano-praha na čelik za izradu ortopedskih implantata 316LVM
(Association of the Chemical Engineers of Serbia, 2011)
Hydroxyapatite is a widely used bioceramic material in implant coatings research because of its bioactive behavior when being deposited onto the metallic implant and compatibility with the human bones composition. The ...
Correlation analysis of IR, 1H- and 13C-NMR spectral data of N-alkyl and N-cycloalkyl cyanoacetamides / Korelaciona analiza IR, 1H- i 13C-NMR spektalnih podataka N-alkil- i N-cikloalkilcijanoacetamida
(Association of the Chemical Engineers of Serbia, 2011)
Linear free energy relationships (LFER) were applied to the IR, 1H- and 13C- -NMR spectral data in N-alkyl and N-cycloalkyl cyanoacetamides. N-alkyl and N-cycloalkyl cyanocetamides were synthesized from corresponding amine ...
A comparative study of the removal of lead, cadmium and zinc ions from aqueous solutions by natural and Fe(III)-modified zeolite / Uporedna analiza uklanjanja jona olova, kadmijuma i cinka iz vodenih rastvora adsorpcijom na prirodnom i Fe(III)- modifikovanom zeolitu
(Association of the Chemical Engineers of Serbia, 2014)
The main purpose of this research was to explain the differences in the adsorption mechanisms and adsorption capacities of natural and Fe(III)-modified zeolite for Pb2+, Zn2+ and Cd2+. The adsorbents were characterized ...
The effect of salinity on the sorption of cadmium ions from aqueous medium on Fe(III)-sepiolite / Uticaj saliniteta vode na sorpciju jona kadmijuma na Fe(III)-sepiolitu
(Association of the Chemical Engineers of Serbia, 2015)
In this study, the sorption of cadmium ions onto sepiolite modified with hydrated iron(III) oxide, Fe(III)-sepiolite, has been investigated in natural seawater, artificial seawater, aqueous solution of NaCl of the same ...
