Kinetics of sunflower and used vegetable oil methanolysis catalyzed by CaO·ZnO
(Elsevier Sci Ltd, Oxford, 2013)
The kinetics of heterogeneous methanolysis of sunflower oil and used vegetable oil were studied at different temperatures, ranging from 60 to 96 degrees C using CaO center dot ZnO as catalyst (2 wt% on the basis of oil) ...
Structure and fracture of medium carbon microalloyed steel / Struktura i lom u srednjeugljeničnim mikrolegiranim čelicima
(Univerzitet u Beogradu, Tehnološko-metalurški fakultet, 2013)
Two medium carbon vanadium microalloyed foring steels with different content of carbon and titanium were investigated. Broad goals were to examine transformational behavior of the steels on continuous cooling at still air ...
Silver incorporation on viscose and cotton fibers after air, nitrogen and oxygen DBD plasma pretreatment
(Springer, Dordrecht, 2013)
Dielectric barrier discharge (DBD) pretreatments in air, nitrogen and oxygen plasma of viscose and cotton fabrics with subsequent immobilization of silver were studied. Surface activation of treated fibers was evaluated ...
Procedures for processing of copper secondary raw materials / Postupci prerade sekundarnih sirovina bakra
(Engineering Society for Corrosion, Belgrade, Serbia, 2013)
