(Serbian Chemical Society, 2003)
The structure of a polysaccharide consisting of D-glucose isolated from the cell-wall of active dry baker’s yeast (Saccharomyces cerevisiae) was investigated by using methylation analysis, periodate oxidation, mass ...
Acid-catalyzed and photolytic reactivity of some unsaturated B-nor-5, 10-secosteroidal ketones / Kiselo-katalizovana i fotolitička reaktivnost nekih nezasićenih B-nor-5,10-sekosteroidnih ketona
(Serbian Chemical Society, 2003)
The acid-catalyzed reaction of (Z)- and (E)-B-nor-5,10-seco-ketones 2 and 3 resulted in an intramolecular cyclization to give the 5-hydroxy-A-nor-1β,5β-10(19)-methylidene derivative 8, the 5β-hydroxy-A-nor-1(10)-unsaturated ...
The role of the concentration profile of titanium oxide on the electrochemical behavior of RuO2-TiO2 coatings obtained by the sol-gel procedure / Uloga koncentracionog profila titan-oksida u elektrohemijskom ponašanju RuO2-TiO2 prevlaka dobijenih sol-gel postupkom
(Belgrade : Serbian Chemical Society, 2003)
In order to understand the role of TiO2 in the deactivation mechanism of an active RuO2–TiO2 coating, an additional TiO2 layer was introduced in the support coating interphase of regular Ti//[RuO2–TiO2 anode in one case ...
