Crystal structure of 2-{1-[(1-(2-pyridinio)ethylidene)hydrazono]ethyl} pyridinium diperchlorate, the product of template condensation in the presence of Cr(III)
(Journal of Chemical Crystallography, 2009)
In an attempt to synthesize a Cr(III) complex of 2′-[1-(2-pyridinyl) ethylidene]oxamohydrazide an azine product 2-{1-[(1-(2-pyridinio)ethylidene) hydrazono]ethyl}pyridinium diperchlorate was obtained by an electrophilic ...
The application of modified macroporous poly(GMA-co-EGDMA) in the metal ions sorption from aqueous solutions / Primena modifikovanog makroporoznog poli(GMA-co-EGDMA) kopolimera u sorpciji jona metala iz vodenih rastvora
(Tehnika - Novi materijali, 2002)
Macro porous cross linked poly(GMA-co-EGDMA) copolymer synthesized by radical suspension copolywerization was modified by ring-opening reaction of the pendant epoxy groups with ethylene diamine, EDA. Sorption capacities ...
Stereoselective synthesis of (-)-cytoxazone and (+)-epi-cytoxazone
(Oxford : Pergamon-Elsevier Science Ltd, 2004)
Optically pure (-)-cytoxazone was synthesized, starting from methyl p-methoxycinnamate, in six steps and in 31%, overall yield. The required anti-aminoalcohol configuration was established by combining Sharpless asymmetric ...
Synthesis and characterization of silver—poly(methylmethacrylate) nanocomposites
(Springer, 2009)
The optical properties of silver nanoparticles
embedded in poly(methylmethacrylate) (PMMA) was investigated

Purification and properties of major midgut leucyl aminopeptidase of Morimus funereus (Coleoptera, Cerambycidae) larvae
(Elsevier Science Inc, New York, 2008)
The major leucyl aminopeptidase (LAP) from the midgut of Morimus funereus larvae was purified and characterised. Specific LAP activity was increased 292-fold by purification of the crude midgut extract. The purified enzyme ...
Alkylation of carbonyl compounds in the TiCl4-promoted reaction of trimethylsilyl enol ethers with ethylene oxide
(Oxford : Pergamon-Elsevier Science Ltd, 2000)
Titanium tetrachloride promoted reaction of trimethylsilyl enol ethers with ethylene oxide affords homoaldol type products in moderate/good yields. The reaction is believed to proceed via the titanium enolates. (C) 2000 ...
Isothermal kinetics of (E)-4-(4-metoxyphenyl)-4-oxo-2-butenoic acid release from poly(acrylic acid) hydrogel
(Elsevier, 2007)
The isothermal kinetics of the release of the drug (E)-4-(4-metoxyphenyl)-4-oxo-2-butenoic acid (MEPBA) from poly(acrylic acid) hydrogel were studied. The isothermal kinetic curves of MEPBA release from the poly(acrylic ...
Composition and antibacterial activity of Achillea asplenifolia essential oil
(Allured Publ Corp, Carol Stream, 2002)
The oil of a wild growing population of Achillea asplenifolia Vent. was studied for yield, composition and antibacterial activity. The major components in the oil were beta-caryophyllene (17.6%), germacrene D (15.6%) and ...
