Catalytic oxidations of enolizable ketones using 2-alkylidene-4- oxothiazolidine vinyl bromide
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Direct oxidation of enolizable ketones to α-hydroxy derivatives, vicinal dicarbonyls or tricarbonyl compounds has been achieved by a catalytic amount of 2-alkylidene-4-oxothiazolidine vinyl bromide in DMSO as a solvent. ...
Elektrohemijska redukcija tartrazina na kompozitnim pilarena glina/ugljenik/nafion elektrodama
(Savez inženjera i tehničara Srbije, 2011)
Bentonitna glina iz rudnika Bogovina (Srbija) pilarena je Al3+ i Al3+/Fe3+ polioksokatjonima. Ispitana je mogućnost primene pilarenih glina za elektrohemijsku detekciju tartrazina iz rastvora. Metodom SW voltametrije je ...
Uticaj starenja na morfološke i optičke karakteristike tankih filmova / The Influence of Ageing on the Morphological and Optical Properties of Thin Tpd Films
(Association of Chemical Engineers of Serbia, 2011)
U ovom radu ispitivan je uticaj prirodnog starenja na morfološke i optičke karakteristikeTPD (N,N’-bis(3-metilfenil)-N,N’-difenilbenzidin) tankih filmova. Inicijalno, filmovi su pripremljeni fizičkom vakuumskom depozicijom ...
