Development directions of packaging made from polymer materials / Pravci razvoja ambalaže od polimernih materijala
(Association of Chemical Engineers of Serbia, 2011)
World packaging market achieves turnover of about $620 billion per year with one third of this amount being associated with packaging made from polymer materials. It is expected that this kind of packaging consumption will ...
Prediction of high pressure liquid heat capacities of organic compounds by a group contribution method / Predskazivanje toplotnog kapaciteta organskih tečnosti na visokom pritisku pomoću metode doprinosa grupa
(Serbian Chemical Society, Belgrade, 2011)
A new method for estimating high pressure liquid heat capacities based on molecular structure and group contribution is proposed. A common set of structural groups was employed. The method was developed using 67 sets of ...
The effect of K2O on the crystallization of niobium germanate glasses
(International Institute for the Science of Sintering, Beograd, 2011)
The effect of K2O content on the crystallization of niobium germanate glasses with 22.7- 24.27 wt% of GeO2 and 54.59-57.48 wt% of Nb2O5 was examined. The glasses crystallize by primary crystallization and the formed ...
Enhanced Arsenic Sorption by Hydrated Iron (III) Oxide-Coated Materials-Mechanism and Performances
(Water Environment Federation, 2011)
Mechanism and performances of arsenic(III) [As(III)] and arsenic(V) [As(V)] sorption onto hydrated iron(III) oxide (HFO)-coated materials were investigated at neutral pH where arsenic occurs in both molecular and ionic ...
Synthesis of 5-(substituted phenylazo)-6-hydroxy-4-methyl-3-cyano-2-pyridones from ethyl 3-oxo-2-(substituted phenylazo)butanoates / Sinteza 5-(supstituisanih fenilazo)-6-hidroksi-4-metil-3-cijano-2-piridona iz etil-3-okso-2-(supstituisanih fenilazo)butanoata
(Serbian Chemical Society, Belgrade, 2011)
A new procedure for the synthesis of known azo pyridone dyes is presented. A series of 5-(substituted arylazo)-6-hydroxy-4-methyl-3-cyano-2-pyridones were prepared from ethyl 3-oxo-2-(substituted phenylazo)butanoates and ...
Analysis of selected elements in water in the drinking water preparation plants in Belgrade, Serbia / Analiza odabranih elemenata u vodi u pogonima za pripremu vode za piće u Beogradu
(Association of Chemical Engineers of Serbia, 2011)
Belgrade's water supply relies mainly on the River Sava and groundwater supply wells, which are located in the vicinity of the river and Ada Ciganlija. In this paper, the contents of aluminum, boron, chromium, manganese, ...
Solubility in the ternary system CaSO4 + Na2SO4 + H2O at 298.15 K
(Maik Nauka/Interperiodica/Springer, New York, 2011)
The solubility in the ternary system, aqueous mixture of CaSO4 and Na2SO4, at T = 298.15 K comprises five different salts: calcium sulfate dihydrate, mirabilite, thenardite, glauberite and labile salt. Using the Extended ...
