Study on the morphology and thermomechanical properties of poly(urethane-siloxane) networks based on hyperbranched polyester / Proučavanje morfologije i termomehaničkih svojstava umreženih poli(uretan-siloksana) na bazi hiperrazgranatog poliestra
(Association of Chemical Engineers of Serbia, 2013)
Two series of polyurethane films based on hyperbranched polyester of the second pseudo-generation (Boltorn®), 4,4'-methylenediphenyl diisocyanate and two different siloxane prepolymers, α,ω-dihydroxy-(ethylene oxide-poly ...
Investigation of pretertiary and tertiary surface sediments from Serbia: Organic geochemical interpretation / Ispitivanje pretercijarnih i tercijarnih površinskih sedimenata Srbije - organsko-geohemijska interpretacija
(Association of Chemical Engineers of Serbia, 2002)
Samples of surface sediments originating from different localities in Serbia which contained more than 0.5 % organic matter were investigated in this paper. According to age, these samples were classified into two groups ...
Performances of continuous dryer with inert medium fluidized bed / Performanse kontinualne sušnice sa fluidizovanim slojem inertnih čestica
(Association of Chemical Engineers of Serbia, 2008)
A fluid bed dryer with inert particles represents a very attractive alternative to other drying technologies according to the main efficiency criteria, i.e. specific water evaporation rate, specific heat consumption and ...
Absorption in a three-phase fluidized bed II: Mass transfer investigations / Apsorpcija u koloni sa pokretnim punjenjem II - ispitivanja karakteristika prenosa Mase
(Association of Chemical Engineers of Serbia, 2003)
The absorption of carbon dioxide in aqueous diethanolamine solutions was carried out in a three-phase fluidized bed with inert spherical packing. The rate of absorption was calculated on the basis of measuring the concentration ...
The impact of isatin derivatives on antibiotic production by Streptomyces hygroscopicus CH-7
(Association of Chemical Engineers of Serbia, 2016)
The effect of isatin derivatives as a nitrogen source on antibiotic (hexaene H-85 and azalomycine B) production by Streptomyces hygroscopicus CH-7 was studied. Isatin-3-hydrazone, 5-chloroisatin-3-hydrazone, isatin-3-tos ...
Economizer water-wall damages initiated by feedwater impurities
(Association of Chemical Engineers of Serbia, 2014)
The main causes of efficiency loss in thermal power plants are boiler tube failures that diminish unit reliability and availability, and raise the cost of the electric energy. For that reason, the regular examination of ...
Surface plasmon resonance of Ag organosols: Experimental and theoretical investigations / Rezonance površinskih plazmona organosola srebra - eksperimentalna i teorijska ispitivanja
(Association of Chemical Engineers of Serbia, 2012)
The aim of this study was to investigate and compare the changes in surface plasmon resonance (SPR) of silver (Ag) hydrosol and organosols obtained by experimental and theoretical approaches. Silver nanoparticles (Ag NPs) ...
The use of salicylaldehyde derivatives as a nitrogen source for antibiotic production by Streptomyces hygroscopicus CH-7
(Association of Chemical Engineers of Serbia, 2017)
In the present work, four derivatives of salicylaldehyde (salicylaldehyde-hydrazone, phenylhydrazone, semicarbazone and thiosemicarbazone) were synthesized using both conventional (95% ethanol) and green (crude glycerol ...
Cloning of the gene for a carbohydrate oxidase from Lactuca sativa in the yeasts Saccharomyces cerevisiae and Pichia pastoris / Kloniranje gena za ugljeni hidrat oksidazu iz biljke Lactuca sativa u kvasce saccharomyces cerevisiae i Pichia pastoris
(Assoc Chemical Engineers Serbia, Belgrade, 2015)
We have cloned the gene for carbohydrate oxidase (CHO) from Lactuca sativa in two species of yeasts (Saccharomyces cerevisiae and Pichia pastoris). The synthetic gene Department for Plant Physiology, Institute for Biological ...
Direct liquefaction of soft brown coal from the Kosovo basin / Likvefakcija mekog mrkog uglja kosovskog basena
(Association of Chemical Engineers of Serbia, 2000)
The behavior of Kosovo Basin (Yugoslavia) soft brown coal was studied during a direct liquefaction process by catalytic hydrogenation. A stream of hydrogen was passed through a tetralin dispersion of the pulverized coal ...
