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...

Carbon materials derived from biomass are drawing increasing attention due to its advantages in economical as well ecological production. Among the resources be utilized for that purpose, lignin possesses unique characteristics: it is available bulk quantity a low-value by-product pulp and paper industries chemical structure based on complex aromatic networks provides excellent precursor grahit...

alumina nanomaterials were synthesized via a solution combustion technique using tris-(acetylacetonato) aluminum(iii) complex (1) and tris-(2-formylphenolate) aluminum(iii) complex (2) at 600, and 1000 °c for 3h. the obtained data showed that the procedure without using fuel resulted in a better phase and morphology. to investigate the phase formation, powder x-ray diffraction technique was use...
