Study of supported Pt and PtRu catalysts in methanol and formic acid oxidation
(Trans Tech Publications Ltd, Switzerland, 2004)
The kinetics of methanol and formic acid oxidation on supported Pt and Pt2Ru3 catalysts are measured in 0.5 M H2SO4 at ambient temperature using thin-film rotating disc electrode (RDE) method. Both catalysts are characterized ...
Tetrahydrofuran-type sesquiterpenes from Artemisia lobelii All. var. canescens (DC.) Briqu. and Artemisia lobelii All. var. biasolettiana (Vis.) K. Maly
(Oxford : Pergamon-Elsevier Science Ltd, 2004)
Synthesis of 5-azaandrostane-3β,17β-diol protected at the 17β-hydroxyl group
(Serbian Chemical Society, 2004)
In the present paper, the preparation of 3β-hydroxy-17β-dimethyl- tert-butylsilyloxy-5-azaandrostane (15) in fourteen steps is described. B-nor-17-oxoandrost-5-en-3β-yl acetate (1) 1,2 was used as the starting material, ...
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 ...
Thionation of N-methyl- and N-unsubstituted thiazolidine enaminones / Tionovanje n-metil- i n-nesupstituisanih tiazolidinonskih enaminona
(Serbian Chemical Society, 2004)
The potential of directional non-bonded 1,5-type S···O interactions to initiate the incipient stage of an in situ rearrangement of N-unsubstituted thiazolidine enaminones to functionalized 1,2-dithioles has been demonstrated. ...
Facile rearrangement of push-pull 5-substituted 4-oxothiazolidines induced by pyridinium hydrobromide perbromide under homogeneous reaction conditions / Efikasno premeštanje push-pull 5-supstituisanih 4-oksotiazolidina indukovano piridinijum-hidrobromid-perbromidom pod homogenim reakcionim uslovima
(Serbian Chemical Society, 2004)
Pyridinium hydrobromide perbromide (PHBP) is a highly efficient reagent for the conversion of 5-substituted-2-alkylidene-4-oxothiazolidine derivatives to the corresponding thiazolidines with two fully delocalized exocyclic ...
Protein covalent modification of biologically active quinones / Kovalentne modifikacije proteina biološki aktivnim hinonima
(Serbian Chemical Society, 2004)
The avarone/avarol quinone/hydroquinone couple shows considerable antitumor activity. In this work, covalent modification of β-lactoglobulin by avarone and its derivatives as well as by the synthetic steroidal quinone ...
Modeling of adsorber/desorber/catalytic reactor system for ethylene oxide removal / Modelovanje sistema adsorber/desorber/katalitički reaktor za uklanjanje etilen oksida
(Serbian Chemical Society, 2004)
The removal of ethylene oxide (EtO) in a combined system adsorber desorber/catalytic reactor has been investigated. The combined system was a modified draft tube spouted bed reactor loaded with Pt/Al2O3 catalyst. The annular ...
Electrochemistry of active chromium, part IV: Dissolution of chromium in deaerated sulfuric acid / Elektrohemija aktivnog hroma, deo IV - rastvaranje hroma u deaeriranom vodenom rastvoru sumporne kiseline
(Serbian Chemical Society, 2004)
Chromium dissolution in aqueous sulfuric acid solutions in the pH range 0.5 –3 was studied electrochemically by the potentiostatic or very slow potentiodynamic method, and by the analyses of the Cr ion concentrations in ...
Superoxide dismutase activity as a function of culture aging of B-16 mouse melanoma cells / Aktivnost superoksid-dismutaze tokom maturacije kulture ćelija b-16 melanoma miša
(Serbian Chemical Society, 2004)
The C3 clone of B-16 mouse melanoma was cultured for 1, 6 and 9 days and analyzed. The changes which are not directly linked to melanogenesis in the B-16 / C3 cultures during their maturation were characterized. Early (1 ...
