Stimuli-sensitive hydrogels for pharmaceutical and medical applications / Hidrogelovi osetljivi na spoljne stimulanse za farmaceutsku i medicinsku primenu
(Univerzitet u Nišu, Niš, 2011)
Hydrogels are three-dimensional cross-linked hydrophilic polymers that swell in water and aqueous solutions without dissolving in them. They are very sensitive to environmental stimulus, which is manifested by a sharp phase ...
Influence of the content of hard segments on the properties of novel urethane-siloxane copolymers based on a poly(epsilon-caprolactone)-b-poly(dimethylsiloxane)-b-poly(epsilon-caprolactone) triblock copolymer
(Journal of the Serbian Chemical Society, 2011)
A series of novel thermoplastic urethane-siloxane copolymers (TPUSs) based on a alpha,omega-dihydroxy-[poly(epsilon-caprolactone)-b-poly(dimethylsiloxane)-b-poly(epsilon-caprolactone)] (alpha,omega-dihydroxy-PCL-PDMS-PCL) ...
Biodiesel Fuel Production by Enzymatic Transesterification of Oils: Recent Trends, Challenges and Future Perspectives
(IntechOpen, 2011)
Liquid fuels have been used for many years as the most dominant and basic fuel for motor
engines. However, declining fossil fuel resources as well as the tendency for developing
new renewable biofuels have shifted the ...
Influence of Nuclear Radiation and Laser Beams on Optical Fibers and Components
(Nuclear technology and radiation protection, 2011)
The influence of nuclear radiation and particles has been the object of investigation for a long time. For new materials and systems the research should be continued. Human activities in various environments, including ...
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 ...
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 ...
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, ...
Microstructure evolution of the hot-rolled modified AA 5083 alloys during the two stage thermal treatment
(Savez inženjera metalurgije Srbije, Beograd, 2011)
The effects of the two stage heat treatment on the structure of two hot-rolled 5083 aluminum alloys without and with 0.12% Zr addition were investigated. Combination of the metallographic and transmission electron microscopy ...
Estimation of the correlation between the retention of s-triazine derivatives and some molecular descriptors
(Univerzitet u Novom Sadu, 2011)
In this study, 14 newly synthesized s-triazine derivatives were investigated by means of reversed-phase thin-layer chromatography (TLC) on C-18 stationary and two different mobile phases: acetonitrile-water and methanol-water. ...
Mussels as a bio-indicator of the environmental quality of the coastal water of the Boka Kotorska Bay (Montenegro)
(Journal of the Serbian Chemical Society, 2011)
The Mediterranean blue mussel Mytilus galloprovincialis was used as a pollution level indicator in the Boka Kotorska Bay of the southeastern Adriatic on the Montenegrin coast. The ever-increasing urbanization and ...
