−Deep Eutectic Solvents are promising greener and cheaper alternatives to ionic liquids. The applications involving these solvents depend largely on their physical and chemical properties. However, a DES may possess both desirable and undesirable properties for a certain application. In such situations, mixing two DESs, each possessing a unique set of properties, may yield one with a more suita...

New two nano- sized Schiff base complexes [M(L)], where L= 2, 2'-((1E, 1E')-(1, 2 phenylen bis (azanylylidene)) bis (methanylylidene)) bis (4-bromo phenolato) and M=Cu or Zn, (a, b complexes) were synthesized by ultrasonic irradiation. These complexes were characterized by elemental analysis, molar conductivity, FT-IR, fluorescence emission, 1H NMR, field emission scanning electron spectroscopy...

Five rare earth complexeslanthanum(III),praseodymium(III),neodymium(III), samarium(III) and europium(III) have been synthesized from Schiff base ligand (N,N-bis (2-hydroxy-1-naphthylidene) acetylhydrazone). The complexes were characterized based on elemental analysis, molar conductance, ultraviolet, infrared, mass, thermogravimetric and powder X-ray diffraction studies. Infrared spectra sug...

• A deep eutectic solvent formed by choline chloride and resorcinol (mole ratio 1:2) is presented. comprehensive study of the thermophysical properties this DES has been performed. Two their aqueous mixtures have also thermophysically characterized. All these systems characterized NRM techniques. The solvents increased in recent years. This because great solubility ability lower toxicity than u...

Evidence from diamond inclusions suggests that KCl-bearing fluids may be abundant in the subcratonic mantle and these also cause local anomalies of high electrical conductivity. We therefore measured conductivity aqueous containing 6.96, 0.74 0.075 wt% KCl using a hydrothermal anvil cell to 2.5 GPa 675°C, with piston-cylinder apparatus 5 900°C. found below 550°C, increasing pressure generally d...

While an octahedral cobalt(II) nickel(II) ions [M(H2O)(CPoxS)2(diphos)] when Co receptivity....

In this work we study the effect of some electrical prosperities on synthetic rubber reinforced with carbon black diluted in heptanes with concentrations from 0.2% gm/mole to 2.0% gm/ mole in temperatures range (100, 150, 200, 250, 300) C associated with amount weight of black carbon 5wt% added to the diluted rubber. The results of electrical properties measurement of Buna rubber reinforced wit...

A series of diethylmethyl(2-methoxyethyl)ammonium (DEME)-based ionic liquids were prepared using bis(perfluoroalkanesulfonyl)amide (C(n)F(2n+1)SO(2))(2)N anions with different perfluoroalkyl chain lengths (n = 0, 1, 2, 3, and 4), and the influence of the structural variation on their thermal, ion-diffusive (ionic conductivity and viscosity), ion-concentration (molar concentration and ion associ...

■ Abstract The structural and chemical parameters determining the formation and mobility of protonic defects in oxides are discussed, and the paramount role of high-molar volume, coordination numbers, and symmetry are emphasized. Symmetry also relates to the structural and chemical matching of the acceptor dopant. Y-doped BaZrO 3-based oxides are demonstrated to combine high stability with high...

The complexation of urea (U) with manganese(II), cobalt(II), iron(III) and copper(II) ions at different temperatures has been studied by many methods namely elemnental analysis, magnetic susceptibility, conductivity measurements, infrared and thermal analysis (TG/DTG), scanning electron microscopy (SEM), Energy-dispersive X-ray spectroscopy (EDX), and x-ray powder diffraction (XRD). The high va...
