Determination of ionization constants (PKA) of β-hydroxy-β-arylalkanoic acids using high-pressure liquid chromatography
(University of Kragujevac, Faculty of Science, 2018)
pKa values of five β-hydroxy-β-arylalkanoic acids and ibuprofen were determined using the RP-HPLC method. Stationary phase was octadecyl modified (C-18) silica gel, and mobile phase was a mixture of methanol and one of ...
Elektrohemijsko određivanje antimona na elektrodama sa poli(vinil alkohol)/glina kompozitom / Electrochemical detection of antimony on electrodes based on poly(vinyl alcohol)/clay composites
(Beograd : Savez inženjera i tehničara Srbije, 2019)
Sintetisani su kompoziti gline i poli(vinil alkohola) (PVA) sa masenim odnosima PVA/glina 10% i 20%. Kompoziti su naneti na površinu disk elektrode od staklastog ugljenika pomoću Nafiona. Tako modifikovane elektrode su ...
Aromatic π-networks in Sm/LSm protein interfaces / Aromatična π-mreža u interfejsima Sm/LSm proteina
(Univerzitet u Nišu, 2014)
In this work, we have analyzed the influence of π-π interactions on stability and properties of Sm/LSm assemblies. The residues were found to be involved in π-π interactions much more frequently than Tyr or His. Similarly, ...
