The present research work deals with rapid, simple, precise and robust enantioselective isocratic chiral LC method for the enantiomeric separation of repaglinide using an

The resultant dendrogram was very similar to that obtained from the orange tree leaves, showing first the separation between healthy (I) and diseased (II) orange peels, and

Glycodendrimers 1 - 5 were obtained from the galactopyranoside 9 and the commercially available cores 1,4-butanediamine and tris-(2-ethylamino) amine; commercially

10,11,14,16,32,38-44 In this regard, we had reported the preparation of a rutin multi-walled carbon nanotubes modified glassy carbon electrode (RMWCNT-GCE), 14 a

carboxylic groups presence is obtained by the observation of a peak at 288.8 eV (Figure S3b), which is typical for this functional group. This observation of carbon in the amide

In order to study the speciation of Al 3+ hydrolytic complexes, the ESI-MS spectra were recorded at different pH values (3.20 to 6.20) and at a constant aluminum concentration

Additionally, a strong positive correlation was established between the concentration of Fe in the hydrophobic fraction assessed and the optical density of dark honeys, indicating

The main goals were: ( i ) to obtain reliable spectroscopic constants for E119F at different electron correlation levels and compare with those obtained neglecting the SS
