The kinetics and mechanism of metal ion catalysis in the oxidation of ascorbic acid have been the subject matter of several studies. The catalytic oxidation of ascorbic acid in the presence of Cu(II) and Fe(I'.|I) ions and their complexes in aqueous medium have been reportedl-6. As has been mentioned in the previous chapter, among the various metal complexes synthesised, only the Cu(]I) complex...

a novel ternary schiff base ligand (hl) of ono type and its copper (ii) complex weresynthesised using 2-aminophenol and o-acetoacetotoluidide. they have been characterised by theusual analytical and spectral methods. the interaction of the complex with calf-thymus (ct)dna has been investigated by uv-vis, viscosity measurement, cyclic voltammetry anddifferential pulse voltammetry studies. the re...

Sir, Body dysmorphic disorder (BDD) is primarily a psychiatric condition, but frequently found in dermatologi-cal settings, where it often goes undetected (1). BDD is characterized by subjective beliefs of physical ugliness or disfigurement despite an objectively normal appearance. Often minor blemishes are blown out of proportion. The affected individual is convinced that others perceive them ...

Graphitic carbon nitride (g-C3N4) is a metal-free heterogeneous catalyst that has attracted attention because of its good chemical stability, cost-effectiveness, and environmental friendliness. In the work presented herein, F,O,S-codoped was synthesized by heating mixture melamine cyanurate trifluoromethanesulfonic acid at 550 °C for 50 min. The obtained product characterized transmission elect...

The activity of alginic acid as a cytotoxic agent was improved by structure modification using 4-aminophenol (4-AP) through condensation and polymerization processes. Then, silver nanoparticles were employed doping to further enhance the modified polymer. prepared materials characterized FT-IR, 1HNMR, UV spectroscopy, X-ray diffraction, electron microscopy, thermal behavior all synthesized inte...

We have selected and spatially separated the two conformers of 3-aminophenol (C6H7NO) present in a molecular beam. Analogous to the separation of ions based on their mass-to-charge ratios in a quadrupole mass filter, the neutral conformers are separated based on their different mass-to-dipole-moment ratios in an ac electric quadrupole selector. For a given ac frequency, the individual conformer...
