“…The substitution of these ions during the synthesis yields trirutile-type crystalline structures with spatial groups P4 2 /mnm (MgSb 2 O 6 , NiSb 2 O 6 , CoSb 2 O 6 ) [9,15,16] and P2 1 /n or P2 1 /c (CuSb 2 O 6 ) [17]. Some authors state that substituting the Mn ion (in order to obtain the manganese antimonate, MnSb 2 O 6 ), the compound may show a hexagonal or columbite-type crystal structure with spatial group P321 [18], displaying also a strong similarity to the trirutile-type structures of the FeSb 2 O 6 , the CoSb 2 O 6 and the NiSb 2 O 6 [19].…”

Nanoparticles of manganese antimonate (MnSb2O6) were prepared using the microwave-assisted colloidal method for its potential application as a gas sensor. For the synthesis of the oxide, manganese nitrate, antimony chloride, ethylenediamine and ethyl alcohol (as a solvent) were used. The precursor material was calcined at 800 °C in air and analyzed by X-ray diffraction. The oxide crystallized into a hexagonal structure with spatial group P321 and cell parameters a = b = 8.8054 Å and c = 4.7229 Å. The microstructure of the material was analyzed by scanning electron microscopy (SEM), finding the growth of microrods with a size of around ~10.27 μm and some other particles with an average size of ~1.3 μm. Photoacoustic spectroscopy (PAS) studies showed that the optical energy band (Eg) of the oxide was of ~1.79 eV. Transmission electron microscopy (TEM) analyses indicated that the size of the nanoparticles was of ~29.5 nm on average. The surface area of the powders was estimated at 14.6 m2/g by the Brunauer–Emmett–Teller (BET) method. Pellets prepared from the nanoparticles were tested in carbon monoxide (CO) and propane (C3H8) atmospheres at different concentrations (0–500 ppm) and operating temperatures (100, 200 and 300 °C). The pellets were very sensitive to changes in gas concentration and temperature: the response of the material rose as the concentration and temperature increased. The results showed that the MnSb2O6 nanoparticles can be a good candidate to be used as a novel gas sensor.

EW copper (II), nickel (II) Schiff base complexes derived from ………3,3-dimethoxybenzidine and selected aldehydes, namely 2,4-dihydroxybenzaldehyde with the metal salts have been synthesized using a simple technique of microwave method (Green chemistry). The physical properties of prepared ligand and its metal complexes were recorded. The ligand and complexes were characterized using elemental analysis, NM R, infrared and also their geometrical structure were investigated using spectral UV-Vis reflectance, magnetic susceptibility, electron spin resonance (ESR), thermal gravimetric analysis (TGA) and scan electron microscope (SEM ). The performance tests (oil absorption, fineness of grind, moisture content, and pH and bleeding test in different solvents) of the solid metal complexes were explored to ensure that the complexes can be used as a pigments in the field of anticorrosive paints without any compatibility problems in the paint's vehicle. The anticorrosive paints were formulated based on the prepared metal complexes as a pigments and the Physical, mechanical, colour properties and corrosion resistance of dry paint films were also examined. The obtained results revealed that the prepared metal complex pigments showed excellent mechanical, corrosion resistance with colour stability and did not effect or react with the other components in the anticorrosive paint formula.

“…There is limited data on mixed calcium-copper phase reactivity reported in literature, though some physical data has been reported (Fouad et al, 2012) (Hess et al, 2007). In order to further investigate the CaCu2O3 and Ca2CuO3 mixed phases observed in the combined material, and to ensure that an 870°C reduction temperature is indeed sufficient for the complete reduction of mixed phases, the CuO40_R2 material was subjected to three consecutive TPR / TPO measurements.…”
