The influence of bonding agents in improving interactions in composite propellants, determined using the FTIR spectra / Uticaj vezujućih agenasa na poboljšanje interakcija u kompozitnim gorivima utvrđen korišćenjem FTIR spektara
(Military Technical Institute, Belgrade, 2009)
Bonding agents synthesized in this research are 1, 3, 5-trisubstituted isocyanurates (substituents: 2-hydroxyethyl, 3-hydroxypropyl, 2-hydroxypropyl and 2, 3-epoxypropyl). All syntheses reactions were carried out according ...
The analysis of different processes of extraction: yield of extracts obtained from Aloe vera (Aloe barbadensis Miller) and sweet bay (Laurus nobilis L.) and the exergy analysis of applied processes
(Association of the Chemical Engineers of Serbia, 2009)
The present study was aimed to investigate and compare the efficiency of different methods for the isolation extract from a plant material. Extracts from dried leaves of Aloe vera (A. barbadensis Mill.) and Sweet Bay (Laurus ...
The ultrasonic and image analysis method for non-destructive quantification of the thermal shock damage in refractory specimens
(Elsevier Sci Ltd, Oxford, 2009)
In the present work, Mg-exchanged zeolit and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 50:50. Samples were exposed to the water quench test from 950 ...
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 ...
