Određivanje sadržaja teških metala u čajevima sa tržišta u Beogradu, Srbija / Determination of heavy metal concentrations in tea samples taken from Belgrade market, Serbia
(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 ...
Characterization of electrochemically synthesized pani on graphite electrode for potential use in electrochemical power sources / Elektrohemijska sinteza i karakterizacija elektrode od polianilina za potencijalnu upotrebu u elektrohemijskim izvorima energije
(Inženjersko društvo za koroziju, Beograd, 2009)
Polyaniline (PANI) on graphite electrode was synthesized electrochemically under galvanostatic condition at current density of 2.0 mA cm-2 from aqueous solution of 1.0 moldm-3 HCl and 0.25 mol dm-3 aniline monomer. ...

Swelling behaviour and paracetamol release from poly(N-isopropylacrylamide-itaconic acid) hydrogels
(Springer, New York, 2009)
Copolymer hydrogels of N-isopropylacrylamide and itaconic acid (IA), crosslinked with N,N'-methylenebisacrylamide, were prepared by radical copolymerization. These hydrogels were investigated with regard to their composition ...
ESI-MS spectra of 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)-pyridinones / ESI-MS spektri 3-cijano-4-(supstituisani fenil)-6-fenil-2(1H)-piridinona
(Serbian Chemical Society, Belgrade, 2009)
Twelve 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)-pyridinones were investigated by tandem mass spectrometry using positive as well as negative electrospray ionization. The influence of the electron affinity of the ...
Development and application of crack parameters
(Springer, Dordrecht, 2009)
The development, definition and implementation of crack parameters (stress intensity factor, crack tip open displacement, J integral, filial stretch zone) are presented. They are now used for structural integrity and ...
Incorporation of poly(N-isopropylacrylamide)/chitosan microgel onto plasma functionalized cotton fibre surface
(Elsevier, Amsterdam, 2009)
In the present study, non-thermal plasma treatments using three different gases (air, nitrogen and argon) were used to activate the cotton surface for subsequent poly(N-isopropylacrylamide)/chitosan microgel (PN/CS) ...
Preparation and properties of low cement castable sintered at different temperatures
(University of Novi Sad, 2009)
The low cement high alumina castable (LCC) studied in this paper was synthesised, cured and then treated at different sintering temperatures. Since any inhomogeneity introduced during the castable preparation can remain ...
