A novel methyl (Z)-2-(2-(2-oxonaphthalen-1(2H)-ylidene)hydrazineyl)benzoate isomer ligand has been prepared instead of (E)-methyl 2-((2-hydroxynaphthalen-1-yl)diazenyl)benzoate in very good yield. The tautomerization diazene to hydrazine was computed via DFT; the single proton S(6) process confirmed by XRD. Moreover, XRD-crystal measurements supported form as preferred kinetic isomer; structure...

Synthesis of novel Schiff base from 2-hydroxy-6-methylquinolin-3-carbaldehyde and 4-methyl-benzenesulfonohydrazide has been carried out in the present work. Also, metal complexes Cu(II), Ni(II), Co(II) Cd(II) have synthesized. were characterized by various analytical techniques such as CHN analyzer, XRD, FT-IR, UV-Visible, ESR, 1H NMR, 13C MASS TGA. Very low value molar conductance indicates no...

Oxide nanoparticles of Fe-Co-Ni were prepared in six different compositions by co-precipitation method. The as-synthesized nanoparticles were characterized by X-Ray Diffraction (XRD), Field Emission Scanning Electron microscope (FESEM), Fourier Transform Infrared (FT-IR) and Vibrating Sample Magnetometer  (VSM). It was found that the nanoparticles had mean crystalline size of 30-55 nm and spher...

2-[3-(2-Formylnaphthoxy)-2-hydroxypropoxy] naphthaldehyde (1) have been prepared by reaction of 2-hydroxynaphthaldehyde with 1,3-dichloro-2-propanol. New N2O3 macro-acyclic ligands (L1, L2) synthesized from the reaction of (1) with aniline or cyclohexylamine. Ni (II), Co (II) and Cu (II) complexes was prepared from reaction of Schiff-bases with metal chloride and nitrate salts. All of these com...

The coking process produces great volumes of wastewater contaminated with pollutants such as cyanides, sulfides and phenolics. Chemical and physical remediation of this wastewater removes the majority of these pollutants; however, these processes do not remove phenol and thiocyanate. The removal of these compounds has been effected during bioremediation with activated sludge containing a comple...

Soft X-ray absorption spectroscopy coupled with nano-scale microscopy has been widely used in material science, environmental science, and physical sciences. In this work, the advantages of soft X-ray absorption spectromicroscopy for plant biopolymer research were demonstrated by determining the chemical sensitivity of the technique to identify common plant biopolymers and to map the distributi...
