Mathematical model for exergy in the system NaCl-H2O / Matematički model za eksergiju u sistemu NaCl-H2O
(Association of Chemical Engineers of Serbia, 2004)
In this work mathematical models for the exergy and relative enthalpy of the water solution of sodium-chloride and the pure crystalline sodium-chloride where derived. The environment was defined with the temperature 20 °C, ...
Semi-interpenetrating polymer networks based on polyacrylamide and poly(itaconic acid) / Semi-interpenetrirajuće mreže na bazi poliakrilamida i poli(itakonske kiseline)
(Association of Chemical Engineers of Serbia, 2003)
The effect of pH and temperature on the equilibrium swelling properties of PIA/PAAm semi-IPNs were investigated.Semi-IPNs based on polyacrylamide (PAAm) and poly(itaconic acid) (PIA) were prepared by two different techniques, ...
Heterogeneous base-catalyzed methanolysis of vegetable oils: State of art / Heterogena bazno katalizovana metanoliza biljnih ulja - presek stanja
(Association of Chemical Engineers of Serbia, 2010)
Today, homogeneous base-catalyzed methanolysis is the most frequently used method for industrial biodiesel production. High requirements for the quality of the feedstocks and the problems related to the huge amount of ...
Biodegradable polyesters based on succinic acid / Biodegradabilni poliestri na bazi ćilibarne kiseline
(Association of Chemical Engineers of Serbia, 2003)
Two series of aliphatic polyesters based on succinic acid were synthesized by copolymerization with adipic acid for the first series of saturated polyesters, and with fumaric acid for the second series. Polyesters were ...
Electrostatic generation of alginate microbeads loaded with brewing yeast
(Association of Chemical Engineers of Serbia, 2004)
Drying of biological materials in a spout-fluid bed with a draft tube / Sušenje bioloških materijala u fontansko-fluidizovanom sloju
(Association of Chemical Engineers of Serbia, 2002)
The possibility of applying a spout-fluid bed with a draft tube and conical bottom was investigated for drying fluid media with a certain content of suspended material was investigated. The major goal who to study the ...
Polymers contamination by heavy metal compounds / Kontaminacija polimera teškim metalima
(Association of Chemical Engineers of Serbia, 2002)
The contamination of important synthetic (surface unmodified) polymers by various heavy metal compounds (such as copper, manganese and lead) in aqueous medium was investigated in this study. The influence of the pH of the ...

(Association of Chemical Engineers of Serbia, 2005)
The corrosion behavior and thermal stability of epoxy coatings electrodeposited on mild steel and on mild steel with electrochemically deposited polyaniline (PANI) film were investigated by electrochemical impedance ...
Synthetic lubricants based on copolymers of n-butyl methacrylate and α-olefins / Sintetička maziva na bazi kopolimeran-butilmetakrilata i α-olefina
(Association of Chemical Engineers of Serbia, 2002)
Synthetic fluids obtained by the copolymerization of α -olefins with alkyl esters of unsaturated carboxylic acids have a unique combination of properties of non-polar poly-a-olefins (PAOs) and polar esters in a single ...
Remediation of environment contaminated by lead using synthetic and natural apatites / Stabilizacija zagađenja olovom korišćenjem sintetičkih i prirodnih apatita
(Association of Chemical Engineers of Serbia, 2001)
Lead contamination is an environmental concern due to its effect on human health. One of the ways of remediating lead contamination is the in situ stabilization of this heavy metal. This can be achieved by converting ...
