A fast and non-destructive voltammetric method to detect cocaine in confiscated samples based on carbon paste electrode modified with methoxy-substituted N,N'-ethylene-bis(salcylideneiminato)uranyl(VI)complexes, [UO2(X-MeOSalen)(H2O)] · H2O, where X corresponds to the positions 3, 4 or 5 of the methoxy group on the aromatic ring, is described. The electrochemical behavior of the modified electr...

Monocationic gold(III) complexes with histidine-containing peptides, glycyl-L-histidine (Gly-L-His) and L-alanyl-L-histidine (L-Ala-L-His) have been synthesized and characterized by (1)H NMR spectroscopy and X-ray crystallography. The crystallized Au(III) complexes, [Au(Gly-L-His-N,N',N'')Cl]NO(3)·1.25H(2)O and [Au(L-Ala-L-His-N,N',N'')Cl]NO(3)·2.5H(2)O, were obtained from water solution at pH ...

Realizaram-se estudos cinéticos envolvendo a reação de redução de tris(oxalato)cobaltato por L-ácido ascórbico, em diferentes valores de pH. A variação da concentração do complexo de Co(III) foi acompanhada pela absorbância em 600 nm, em condições de pseudo-primeira ordem: [H 2 A] = 3,0 x 10 mol L, [Co(C 2 O 4 ) 3 ] = 3,0 x 10 mol L, na presença de CDTA (3,0 x 10 mol L), em I = 1,0 mol L (NaCl)...

The kinetics of the oxidation of ruthenium(III) (Ru(III)) catalyzed oxidation of L-tryptophan (L-trp) by diperiodatocuprate(III) (DPC) in aqueous alkaline medium at a constant ionic strength of 0.20 mol dm -3 was studied spectrophotometrically. The reaction between L-tryptophan and DPC in alkaline medium in presence of [Ru(III)] exhibits 1:4 stoichiometry (L-trp:DPC). The reaction was of first ...

هدف این مقاله مطالعه، بررسی و معرفی سفال دورۀ شیماشکی در درۀ سیمره است. بررسی­های باستان­شناسی حاکی از اینست که در دوران مفرغ، سنّت سفال منقوش گودین iii در درۀ سیمره رواج داشته و تنها یک­بار، در روند توسعۀ این نوع سنّت سفالگری خلل ایجاد شده و آن، هم­زمان با مرحلۀ گودین iii4 است که در این زمان با نفوذ سفال دوره شیماشکی دشت شوشان در درۀ سیمره مواجه­ایم و سفال­های شاخص آن در بررسی­های قلعه­زینل و غا...
