Aqueous solutions of polyphenols extracted from parsley leaves are mixed with solution ferric chloride hexahydrate to synthesize suspensions polyphenol-coated iron oxide nanoparticles, which then used prepare Pickering oil (n-decane)-in water emulsions. The performance the nano-colloid and emulsions as agents enhanced recovery (EOR) is assessed secondary imbibition tests performed under constan...

Novel eutectic mixtures have been produced using calcium chloride hexahydrate as the hydrogen bond acceptor, together with ethylene glycol donor. The liquids are found to increased conductivity, decreased viscosity and a lower glass transition temperature compared most deep solvents quaternary ammonium salts. Additionally, metal speciation was be almost same in commonly-used choline chloride: D...

This work presents the evaluation of iron oxide nanoparticles obtained from aqueous extract Eucalyptus grandis. Twenty-three experiments were carried out where synthesis was performed by using together with salts (II) chloride tetrahydrate and (III) hexahydrate. A characterization IR, TEM BET, bands presented at 3,440.77, 1,559.26 445.31 cm−1, indicating presence nanoparticles. relatively high ...

Ni2O3 nanomaterial, a phase of nickel oxide, is synthesized by simple chemical process. The pure raw materials used in the present process were chloride hexahydrate NiCl2.6H2O and potassium hydroxide KOH utilizing temperature at 250 oC for 2 hour. structural, morphological optical properties specimens investigated employing diverse techniques such as XRD, AFM, SEM UV-Vis, respectively. XRD tech...

A set of multicomponent perovskite oxide nanoparticles based on La1-xSrxCo1-yFeyO3-δ(LSCF) were prepared by a simple chemical precipitation method for application in low temperature solid oxide fuel cells (LT-SOFC) as cathode materials.  The precursor materials used in this synthesis were lanthanum nitrate hexahydrate [La(NO3)<su...

The objective of this research is to study the influence film thickness on optical and electrical properties prepared NiO thin films. Nickel oxide films have been glass substrates by a spin coating technique using nickel nitrate hexahydrate (Ni(NO 3 ) 2 .6H O) as source materials. process was repeated 11, 13, 15, 17 layer times obtain good film. characterizations were observed be dependent each...

cobalt chromite (cocr2o4) with normal spinel structure, shows catalytic activity for oxidation of unburned methane in the natural gas vehilcles (ngv). in this study, cocr2o4 nanoparticles were synthesized through a conventional co-precipitation technique and investigated for the catalytic combustion of methane. cobalt nitrate hexahydrate, chromium nitrate nonahydrate and ammonia solution (25%) ...

iron oxide (fe2o3) nanoparticles were synthesized by a simple approach using sodium borohydride (nabh4) and iron chloride hexahydrate (fecl3.6h2o). their physicochemical properties were characterized by high resolution transmission electron microscopy (hrtem), scanning electron microscopy (sem), x-ray diffraction (xrd) and electron dispersive spectroscopy (eds). xrd pattern showed that the iron...
