in this work, the practicality of catalytic surfaces of nano-structured co3o4 and mnco2o4 for the adsorption and neutralization reactions of dimethyl methyl phosphonate (dmmp) as an toxic agricultural organo-phosphorous pesticide has been investigated. the co3o4 and mnco2o4 nps have been successfully prepared by precipitation method using cobalt nitrate and manganese nitrate as the precursors a...

In this study, cobalt aluminate was prepared by a sol-gel method. XRD and FTIR analyses of the precursors obtained at 300 °C for 12 h revealed that type complexing agent used in synthesis affects pyrolysis step. An amorphous phase using citric acid as agent. A beginning crystallization observed agents such polyacrylic glycine. The structural investigation starting reagents lines exhibit charact...

the structural and electrical properties of polyaniline-cobalt sulphate nanocomposite prepared by chemical method.polyaniline-cobalt sulphate nanocomposites were synthesized by the cobalt sulphate and ammonium persulphate and aniline.this paper reports on chemical technique using for synthesis of cobalt nanoparticles in the composite bridge is aniline. electrical conductivity of polyaniline wit...

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...

This study evaluated the effect of modified tetracycline on the resin-dentin bond strength (µTBS), silver nitrate uptake (SNU) and solution homogeneity (SH) of two adhesives. Dentin surfaces were treated with phosphoric acid, rinsed off and either rewetted with water (control group - CO), 2% minocycline (MI), 2% doxycyline (DO) or 2% chlorhexidine (CH). Adhesive systems (Adper Single Bond 2 and...

A red block-shaped crystal of the title compound, [Co(HCOO)2(C12H10N4)2] n , was obtained by the reaction of cobalt(II) nitrate hexa-hydrate, formic acid and 1,1'-(1,4-phenyl-ene)bis-(1H-imidazole) (bib) mol-ecules. The asymmetric unit consists of one Co(II) cation, one formate ligand and two halves of a bib ligand. The central Co(II) cation, located on an inversion centre, is coordinated by tw...

The hydrothermal reaction of cobalt(II) nitrate hexahydrate with 5-(benzimidazol-1ylmethyl)isophthalic acid (H2L) leads to the formation of a complex [Co(L)] (1). In the presence of 2-(pyridin-2-yl)-1H-benzimidazole (pybim) as an auxiliary ligand, a complex [Co(L)(pybim)]·H2O (2) was obtained. The complexes 1 and 2 have been characterized by single-crystal and powder X-ray diffraction, IR spect...
