The title compound, bis-[4,4'-(propane-1,3-di-yl)-dipiperidin-ium] β-octa-molybdate(VI), (C(13)H(28)N(2))(2)[Mo(8)O(26)], was produced by hydro-thermal reaction of an acidified aqueous solution of Na(2)MoO(4)·2H(2)O and 4,4'-trimethyl-ene-dipiperidine (L). The structure of the title compound consists of β-octa-molybdate(VI) anion clusters and protonated [H(2)L](2+) cations. The octa-molybdate a...

In this research, we have studied the structural propenies of water. methanol and ethanol surrounding snidewalledcarbon nanotube (SWCNT) and mixed of them either and we have investigated the solvent effects onthe relative energies and dipole moment values by ming molecular dynamics simulation. We used differentforce field it, deterrnaned energy and other type of geometrical parameters, on the p...

The high temperature properties of Rb3H(SO4)2 have been studied by calorimetry, impedance spectroscopy and X-ray powder diffraction under moderate humidification. At ~205 °C the conductivity of Rb3H(SO4)2 increases sharply, rising from 3.3×10 −5 to 1.9×10 S/cm, suggestive of a polymorphic, superprotonic phase transition. This conductivity anomaly is accompanied by an endothermic thermal event w...

The title compound, bis-[2,2'-dimethyl-3,3'-(butane-1,4-di-yl)diimidazol-1-ium] β-octa-molybdate(VI), (C(12)H(20)N(4))(2)[Mo(8)O(26)], was produced by hydro-thermal reaction of an acidified aqueous solution of Na(2)MoO(4) and 1,4-bis-(2-methyl-1H-imidazol-1-yl)butane (hereafter L). The structure of the title compound consists of the β-octa-molybdate anions having a center of symmetry, and proto...

Estimation of inorganic phosphate in serum based on the formation of "molybdenum blue" may be simplified by eliminating the reduction stage. The yellow complex formed by the reaction of phosphate with molybdate in an acid medium is measured at 390 nm. The yellow complex behaves in accordance with Beer's law over a wide concentration range (to at least 80 mg of P per liter in the initial sample)...

This work reports the preparation of a Tc generator based on conversion of Mo produced by neutron irradiation, into insoluble magnesium Mo-molybdates compounds as matrix. The effect of magnesium salt types and concentration, Mg:Mo molar ratios, pH of molybdate solutions, eluate volume as well as the addition order of molybdate and magnesium solutions’ influences on the final Tc were evaluated. ...
