The optimization of zinc dialkyldithiocarbamates synthesis and determination of their antioxidant activity
(Association of the Chemical Engineers of Serbia, 2008)
A two-step optimized laboratory synthetic method of zinc dialkyldithiocarbamates is presented. In the course of the first phase, a sodium salt of dialkyldithiocarbamic acid has been synthesized from the dialkylamines, ...
Damage detection of hybrid aramid/metal-PVB composite materials using optical fiber sensors
(Association of the Chemical Engineers of Serbia, 2009)
Embedding optical fiber sensors within laminar thermoplastic composite material results in forming a system known as 'smart structure'. These sensors present the information about the inner structure health during the ...
Photocatalytic degradation of textile dye CI Basic Yellow 28 in water by UV-A/TiO2
(Association of the Chemical Engineers of Serbia, 2007)
CI Basic Yellow 28 (BY28), commonly used as a textile dye, could be photocatalytically degraded using TiO2 as catalyst and irradiated by UV-A lamp (300 W). However, UV and TiO2 showed no effect on the photodegradation when ...
Fluid dynamics of gas - flowing solids - fixed bed contactors
(Association of the Chemical Engineers of Serbia, 2007)
Fluid dynamics studies of countercurrent gas - flowing solids - fixed bed contactors are presented in this review. The up-to-date research findings about the basic fluid dynamics parameters: flowing solids holdup, pressure ...
The immobilization of lipase on Sepabeads: Coupling, characterization and application in geranyl butyrate synthesis in a low aqueous system
(Association of the Chemical Engineers of Serbia, 2008)
Lipase from Candida rugosa immobilized on Sepabeads EC-EP was shown to catalyze the esterification of geraniol with butyric acid in a predominantly organic system. The immobilization procedure was adjusted to optimize the ...
Microencapsulation in the textile industry / Mikroinkapsulacije u tekstilnoj industriji
(Association of the Chemical Engineers of Serbia, 2006)
The application of microencapsulation techniques offers the possibility of producing novel products with many advantages compared to traditional textile products. The microcapsules can introduce important new qualities to ...
A study of the photocatalytic degradation of methomyl by UV light
(Association of the Chemical Engineers of Serbia, 2009)
The photocatalytic degradation of insecticide methomyl in water, using TiO2 and ZnO (Merck), under UV (366 nm) was studied. The influence of the catalyst concentration and pH was investigated. The optimal concentration of ...
Design and optimization of purification procedure for biodiesel washing
(Association of the Chemical Engineers of Serbia, 2009)
Almost complete methanolysis of triglycerides is usually not enough to fulfil the strict standards of biodiesel quality. A key step in this process is neutralization of alkali (catalyst) followed by the washing procedure ...
In situ lead stabilization using natural and synthetic apatite
(Savez hemijskih inženjera, Beograd, 2008)
In this work, mineral apatite was investigated for the remediation of lead contamination. Two different apatite minerals were used: synthetic apatite, Ca10(PO4)6(OH)2 (hereafter denoted as HAP) and natural apatite from ...
Effects of cell addition on immobilization by electrostatic droplet generation / Uticaj prisustva ćelija u procesu elektrostatičke ekstruzije alginata
(Association of the Chemical Engineers of Serbia, 2005)
In this study, an attempt was made to assess the effects of cell addition and final concentration on the process of electrostatic extrusion as a method for cell immobilization in alginate microbeads. The electrostatic ...
