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, 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 ...
Reaction of silyl ketene acetals with epoxides: a new method for the synthesis of gamma-butanolides
(Oxford : Pergamon-Elsevier Science Ltd, 2004)
Titanium tetrachloride promoted reaction of silyl ketene acetals with epoxides, followed by acidic work-up, affords butanolides in moderate/good yields. With epihalohydrins the reaction is regioselective and occurs at the ...
Photochemical and Beckmann rearrangement of (Z)-cholest-4-en-6-one oxime / Fotohemijsko i Bekmanovo premeštanje(z)-holest-4-en-6-on oksima
(Serbian Chemical Society, 2004)
Beckmann rearrangement of (Z)-cholest-4-en-6-one oxime (4) (prepared in 4 steps starting from cholest-5-en-3β-ol ο1)) with thionyl chloride in dioxane solution afforded an enamide-type lactam, i.e. 7-aza-B-homocholest-4-en-6-one ...
Interpretation of Serbian surface sediment maturation parameters based on factor analysis / Primena faktorske analize u interpretaciji maturacionih parametara površinskih sedimenata Srbije
(Serbian Chemical Society, 2004)
The factor analysis, used in this work for the interpretation of maturation parameters observed in an exploration study of a group of surface sediments of diverse age originating from different localities in Serbia, resulted ...
Flavonoids from flowers of Cephalaria pastricenis and their antiradical activity / Flavonoidi iz cvetova Cephalaria pastricensis i njihova antiradikalska aktivnost
(Serbian Chemical Society, 2004)
Two flavonoid glycosides 1 and 2 having the luteolin structure were isolated from flowers of the endemic plant species Cephalaria pastricensis. They were identified by 1H and 13C NMR, as well as UV/Vis spectroscopy. The ...
Methanol oxidation at platinum electrodes in alkaline solution: comparison between supported catalysts and model system
(Elsevier, 2004)
Methanol oxidation was studied in 0.1 M NaOH at supported Pt electrodes, and compared with the single crystal Pt electrodes, Pt(1 1 1), Pt(1 1 0) and Pt(3 3 2), chosen as model systems, and with a polycrystalline Pt ...
The effect of preparation of aluminum surface on surface roughness / Uticaj pripreme površine aluminijuma na površinsku hrapavost
(Belgrade, Serbia : Engineering Society for Corrosion, 2004)
Aluminum samples were electrochemically polished in one of three solutions for electrochemical polishing. On those samples the surface roughness was measured. The effect of the anode treatment on surface roughness was also ...
The effect of preparation of aluminum surface on surface reflection / Uticaj pripreme površine aluminijuma na površinsku refleksiju
(Belgrade, Serbia : Engineering Society for Corrosion, 2004)
Aluminum samples were electrochemically polished in one of three solutions for electrochemical polishing. On those samples the surface reflection was measured. The effect of the anode treatment as the interface between the ...
The effect of deposition time on the structure of the top coating of nickel electrodeposited onto aluminum / Uticaj vremena taloženja na strukturu završne prevlake nikla na aluminijumu
(Belgrade, Serbia : Engineering Society for Corrosion, 2004)
The microstructure of the chemical coating of zinc on aluminum, as well as electrodeposited nickel coating on chemically deposited zinc were investigated with change of one parameter only-deposition time. Based on the ...
The effect of the particle shape and structure on the flowability of electrolytic copper powder, III: A model of the surface of a representative particle of flowing copper powder electrodeposited by reversing current / Uticaj oblika I strukture čestica na tečljivost elektrolitičkog bakarnog praha III - model površine reprezentativne čestice tečljivog bakarnog praha dobijenog elektohemijskim taloženjem reversnom strujom
(Serbian Chemical Society, 2004)
The structure of the surface of copper powder particles is discussed and correlated with the lowest apparent density at which copper powder can still flow. It is shown that such structures can be easily obtained in the ...
