WebHowever, stable N 2 species produced by bimolecular combination of fully decomposed atomic species led to the formation of imine groups via atomic rearrangement. Moreover, ion bombardment by N 2 + species adversely affected the chemical structure of the surface, resulting in degradation of ester and carbon-carbon bonds and surface etching of carbon … WebAn azaindole based schiff base AzIm was synthesized that serve as a luminescent turn “off” switch for the detection of Fe 3+ ions. The photoluminescence intensity of AzIm was quenched significantly in the presence of 30 μM Fe 3+ ions. The sensing response of the probe was tested at different ranges of pH and at different cation concentrations between … WebThe poly(2-oxazolines) as well as poly(N-vinyl pyrrolidone) (PVP) were used to prepare solid dispersions with haloperidol, a model poorly soluble drug.
