Cobalt ferrite, Copper ferrite and cobalt doped copper nanoparticles have been synthesized characterized using different characterization methods (XRD, FTIR FESEM). The prepared used as promising fillers of the polyvinylidene fluoride (PVDF) polymer. PVDF/(Cu–CoFe2O4, CoFe2O4, CuFe2O4) nanocomposites films via a simple solution casting technique. optical properties piezoelectric response nanoco...

This work studies the process of formation spinel structure nickel (II) -copper ferrite. A possible mechanism for single-phase samples is considered. It consists stage chelate complexes (II), copper iron (III) cations with citric acid and their subsequent thermal decomposition. The materials obtained are studied by X-ray phase analysis BET technique. catalytic activity synthesized ferrite Cu 0....

Magnetorheological elastomer (MRE) is a smart material whose its damping and stiffness characteristics change when exposed to magnetic field. MRE usually contains rubber ferrous particles. Other materials such as additives, can improve physical properties of during cyclic loading. However, limited research has been conducted into the effect incorporating these additives on performance subjected...

In this research the role of alloying elements on the microstructure and mechanical properties of an as cast and hot rolled high strength low alloy (HSLA) steel was studied. Different compositions with different amount of copper in the presence of nickel, hot rolled and quenched in oil. Tensile test, hardness test, scanning electron microscope (SEM) and optical microscope (OM) were used to eval...

The depletion of fossil energy sources and the legislation regarding emission control demand use alternative fuels rapid progression aftertreatment technologies. study dimethyl ether (DME) catalytic oxidation is important in this respect, as DME a promising clean fuel at same time VOC pollutant present tail gases industrial processes. In work, copper ferrite catalysts synthesized via citrate co...
