(Acta veterinaria, 2006)
The effect of some membrane active ionophoric antibiotics on the amplitude of contractions of isolated rat heart right ventricle was studied. The effects of polyether nigericin, polyene amphotericin B and peptide antibiotic ...
Reactions of α-4(20)-epoxy-5-O-mesyltriacetyltaxicine I induced by Bf3·Et2O/Bu4NBr / Reakcije α-4(20)-epoksi-5-O-meziltriacetiltaksicina I sa tetrabutilamonijum-bromidom u prisustvu bortrifluorid-eterata
(Serbian Chemical Society, 2006)
The reaction of α-4(20)-epoxy-5-O-mesyltriacetyltaxicine I (2) with BF3·Et2O/Bu4NBr can give rise to 4 different products. Each of these products can be obtained selectively, under the appropriate reaction conditions.
Elektrohemijska oksidacija metanola i mravlje kiseline na model i realnim katalizatorima / Electrochemical oxidation of methanol and formic acid on model and real catalysts
(Универзитет у Београду, Технолошко-металуршки факултет, 2006)
Prema svim dosadašnjim saznanjima o okisdaciji metanola za odigravanje ove reakcije neophodo je prisustvo OH čestica na površini elektrode. One su neophodne i za oksidaciju mravlje kiseline po jednom od dva paralelna ...
Activity and stability of RuO2-coated titanium anodes prepared via the alkoxide route / Aktivnost i stabilnost titanskih anoda sa prevlakom od oksida rutenijuma dobijenom alkoksidnim postupkom
(Serbian Chemical Society, 2006)
Titanium anodes with an active RuO2 coating of two different thicknesses were prepared from the oxide suspended in ethanol ("ink" method), while the oxide itself was synthesized by the hydrolysis of ruthenium ethoxide in ...
