(Serbian Chemical Society, Belgrade, 2007)
The essential oil of common juniper (Juniperus communis L., from the southern part of Serbia) and its fractions of different composition, as well as commercial antibiotics were used for testing their antimicrobial activity ...
Electrophoretic deposition of boehmite coatings on titanium from aqueous sols
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
The electrophoretic deposition from sots and colloidal suspensions of ceramic powders has many advantages over conventional ceramic powder processing methods. In this way it is possible to control the thickness and ...
Inverse gas chromatography of chromia, Part I: Zero surface coverage / Inverzna gasna hromatografija hromoksida, Deo I - nulta površinska pokrivenost
(Serbian Chemical Society, Belgrade, 2001)
The surface properties of the solid obtained from colloidal chromia were investigated by inverse gas chromatography (IGC), at zero surface coverage conditions. The solid samples I dried at 423 K and II heated at 1073 K in ...
Noble metal binding on macroporous poly(GMA-co-EGDMA) modified with ethylenediamine / Vezivanje plemenitih metala za makroporozni poli(GMA-co-EGDMA)kopolimer modifikovan sa etilendiaminom
(Serbian Chemical Society, Belgrade, 2004)
Macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), p(GME), was synthesized by suspension copolymerization and modified by reaction of the pendant epoxy groups with ethylenediamine. The ...
NMR analysis of (1S, 1aR, 6aR)-2’, 3’, 6, 6a-tetrahydrospiro cycloprop a indene-1(1aH), 1’- 1H indene / NMR analiza (1S,1aR,6aR)-2’,3’,6,6a-tetrahidro-spiro[cikloprop[a]inden-1(1ah),1’-[ 1h]indena]
