For the first time, dioxomolybdenum(VI) complex with the general formula [MoO2L2] containing a N-O bidentate ligands (HL=2-(o-aminophenyl)- benzimidazole) has been used for the oxidation of sulfides. Elemental analyses (carbon, hydrogen, nitrogen), FT-IR and Uv-Visble spectra and 1HNMR analysis agree well with the proposed stoicheiometry of the complex [MoO...
In this study, Co (III) salen complex was synthesized and immobilized onto the surface of Fe3O4@SiO2 magnetic nanoparticle. The heterogeneous nanocatalyst was characterized by different techniques including X-ray diffraction (XRD), Fourier transform infrared spectra (FT-IR), thermogravimetric analysis (TGA), transmission electron microscopy (TEM), nitrogen adsorption−desorption isotherm (BET), ...
Hysteresis motor is self-starting synchronous motor that uses the hysteresis characteristics of magnetic materials to make torque. There are different methods to model this kind of motor and take into account the magnetic hysteresis characteristic of the rotor hysteresis ring. In this investigation the application of complex permeability concept is implemented to model the hysteresis loop and t...
A new method is developed to enhance the gas separation properties of mixed matrix membranes (MMMs) by interior modification of an inorganic nano-porous particle. Ship-in-a-bottle (SIB), as a novel synthesis strategy, is considered to encapsulate a polyaza macrocyclic Ag-ligand complex into the zeolite Y, which is resulted in a new host-guest nano-composite. It is consequently incorporated into...
