[ 1 ] - Solid State Process for Preparation of Nickel Oxide Nanoparticles: Characterization and Optical Study
In the present work, we report preparation of NiO nanoparticles with well-defined plate morphology by solid-state reaction of NiCl2∙6H2O and the Schiff base ligand N,N′-bis-(3-methoxysalicylidene)benzene-1,4-diamine), as a novel precursor via solid state thermal decomposition method. This method is a simple and environmentally friendly for preparing t...
[ 2 ] - Synthesis and characterization of Schiff-base polymer derived from 2,5-dichloroaniline and 2-hydroxybenzaldehyde
Schiff base sal-2,5-Clan = 2-(2,5-dichlorobenzylideneamino)phenol used as a new precursor for preparation of poly-2-(2,5-dichlorobenzylideneamino)phenol (PDCBAP). In an aqueous alkaline medium, NaOCl oxidant is capable of oxidative poly-condensation reaction (OP). Both sal-2,5-Clan and PDCBAP were characterized by solubility tests, FT-IR, 1H-NMR spectroscopy and TG-DTA studies. FT-IR and 1H-NMR...
