(Savez hemijskih inženjera Srbije, 2009)
U ovom radu su ispitivane koncentracije bakra, cinka, mangana, nikla, kadmijuma i olova u uzorcima čajeva (crni, zeleni, nana, kamilica) uzetih iz lokalnih prodavnica u Beogradu u maju 2008. godine. Priprema uzoraka vršena ...
Photocatalytic degradation of synthetic dye under sunlight / Fotodegradacija sintetske boje pomoću sunčeve svetlosti
(Association of Chemical Engineers of Serbia, 2007)
Synthetic dyes are widely used in the textile industry. Dye pollutants from the textile industry are an important source of environmental contamination. The majority of these dyes are toxic, mostly non-biodegradable and ...
Bioethanol: State and perspectives / Bioetanol - stanje i perspektive
(Association of Chemical Engineers of Serbia, 2006)
Processes of bioethanol production currently applied all over the world are reviewed in this paper. Attention is focused on potentially cheap biomass sources, as well as the most important operating factors controlling the ...
The analysis of loading losses from tank trucks / Analiza gubitaka isparavanja naftnih derivata na primeru auto pretakališta
(Association of Chemical Engineers of Serbia, 2006)
The quantity of loading losses, which are the primary source of evaporative emissions from tank cars and trucks was analyzed in this paper. Loading losses occur as organic vapors in "empty" cargo tanks are displaced to the ...
The thermo-oxidative degradation of poly(2-chloroethyl methacrylate) in the presence of antioxidants / Termooksidativna degradacija poli(2-hloretil metakrilata) u prisustvu antioksidanata
(Association of Chemical Engineers of Serbia, 2000)
The oxidative thermal degradation of poly(2-chloroethyl methacrylate) (PCEMA) was studied in the presence of the following commercial antioxidants: CHIMASSORB 119 (CH 119) and CHIMASSORB 944 (CH 944), both based on amines, ...
Polymer optical fibers today / Polimerna optička vlakna danas
(Association of Chemical Engineers of Serbia, 2000)
Polymer optical fibers (so called POF) are already in wide use in a large number of fields. This paper gives an overview including a background of the development of polymer optical fibers, their advantages, various types ...
Viscoelastic properties of Na-alginate solution
(Association of Chemical Engineers of Serbia, 2004)
The evolution of oscillatory-induced structure of Na-alginate solutions was studied for various frequencies and concentrations. The specific rate of elastic modulus increase, as well as the specific rate of loss modulus ...
The significance and possibility of functional food production / Značaj i mogućnosti proizvodnje funkcionalne hrane
(Association of Chemical Engineers of Serbia, 2002)
Abundant knowledge of the significance of food quality for all human living functions as well as growing human population and the occurrence of world "hidden hunger", directed food producers toward new production processes ...
Biopolymer chitosan: Properties, interactions and its use in the treatment of textiles / Biopolimer hitozan - svojstva, interakcije i primena u obradi tekstilnog materijala
(Association of Chemical Engineers of Serbia, 2004)
The biopolymer chitosan is obtained by the deacetylation of chitin, the second most abundant polysaccharide in nature, after cellulose. It is becoming an increasingly important biopolymer because it offers unique ...
Kinetics of palm oil hydrolysis by lipase immobilized in a hollow fiber membrane reactor
