A novel anode material for intermediate temperature solid oxide fuel cells with a composite of LaxSr1-xTiO3 has been synthesized by a sol-gel auto-combustion method. X-ray diffraction (XRD) shows that LaxSr1-xTiO3 has good chemical compatibility with Gd0.2Ce0.8O1.9 electrolyte. The thermal expansion coefficient (TEC) of the as-prepared anode material is similar to that of Gd0.2Ce0.8O1.9. The el...

Ferrites with spinel structure are the most widespread materials in radio engineering, electronics and communication industry, microwave devices and computer facilities. The change of synthesis temperature of ferrites results in cation redistribution of iron, which updates crystal properties, as macroscopic magnetic properties of ferrites. Among this extensive class of compounds nickel and copp...

Homogeneous Charge Compression Ignition (HCCI) combustion is a pioneer method of combustion in which pre-mixed fuel and oxidizer (typically air) are compressed to the point of auto-ignition. HCCI engines can operate with most alternative fuels, especially, dimethyl ether (DME) which has been tested as a possible diesel fuel due to its simultaneously low NOx and PM emissions. In this paper a ...

The magnetic properties of copper ferrite (CuFe2O4) nanoparticles prepared via sol-gel auto combustion and facile solvothermal method are studied focusing on the effect of nanoparticle arrangement. Randomly oriented CuFe2O4 nanoparticles (NP) are obtained from the sol-gel auto combustion method, while the solvothermal method allows us to prepare iso-oriented uniform spherical ensembles of CuFe2...

In this research nano particles of bismuth ferrite (BiFeO3) were synthesized by sol-gel auto-combustion route. The effect of water and ethylene glycol solvents were studied on phase constituents, magnetic properties and microstructure of the bismuth ferrite by X-ray diffraction (XRD), scanning electron microscope (SEM) and vibration sample magnetometer (VSM) techniques. XRD resul...
