An LFER study of the protolytic equilibria of 4-aryl-2,4-dioxobutanoic acids in aqueous solutions / Linearne korelacije slobodne energije (LFER) protolitičkih ravnoteža 4-aril-2,4-dioksobutanskih kiselina u vodenim rastvorima
(Srpsko hemijsko društvo, Beograd, 2007)
The protolytic equilibria of 13 4-aryl-2,4-dioxobutanoic acids (ADKs) were spectrophotometrically studied in aqueous solutions in the pH range 1-9 at 25±1 °C and an ionic strength of 0.1 mol l-1 (NaCl), with the exception ...
Kinetic study of methanol oxidation on Pt2Ru3/C catalyst in the alkaline media / Kinetika oksidacije metanola na Pt2Ru3/C katalizatoru u alkalnoj sredini
(Serbian Chemical Society, 2007)
The electrochemical oxidation of methanol in NaOH solution was examined on a thin film Pt2Ru3/C electrode. The XRD pattern revealed that the Pt2Ru3 alloy consisted of a solid solution of Ru in Pt and a small amount of Ru ...
