(Kazakhstan : al-Farabi Kazakh National University, 2002)
This paper is aimed at defining two new advantageous maturation parameters based on distribution and abundance of phenanthrene (P) and methylphenanthrene (MP) isomers in the tricyclic fraction of aromatic hydrocarbons: MPI ...
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 ...
Adsorption and corrosion inhibitive properties of some organic molecules on iron electrode in sulfuric acid
(Elsevier, 2002)
Adsorption and corrosion inhibitive properties of three different organic molecules: 2-naphthalenesulfonic acid, 2,7-naphthalenedisulfonic acid and 2-naphthol-3,6-disulfonic acid are investigated on Armco-iron electrode ...
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 ...
Structure and stereochemistry of electrochemically synthesized poly-(l-naphthylamine) from neutral aceto- nitrile solution / Struktura i stereohemija poli-(1-naftilamina) elektrohemijski sintetisanog u neutralnom acetonitrilnom rastvoru
(Serbian Chemical Society, 2002)
Poly-(1-naphthylamine) films were synthesized potentiodinamically and potentiostatically from 1-naphthylamine in neutral acetonitrile medium using a platinum electrode. These polymer films were investigated by infrared ...
Hydride reduction of B-norcholestane 5α,6α-epoxide / Hidridna redukcija B-norholestan 5α,6α-epoksida
(Serbian Chemical Society, 2002)
B-Norcholestane epoxide 2 is reduced with lithium aluminium hydride to give either the 3β,6α-diol 3 or the corresponding 3β,5α-diol 4, depending on the quality of the reducing reagent employed. Aplausible mechanistic ...
