Mixed manganese/copper ferrites having high Curie temperatures and magnetization depending on the composition form an important class of magnetic materials used in many

These characteristics led to high speciic surface, high molybdenum adsorption capacity but low chemical stability, making the material inappropriate for use in 99 Mo/ 99m

thermal changes by TGA, which evidenced weight loss between 100 and 500°C that was attributed to the removal of residual ethylene oxide, so this technique, at a 10°C∙min -1

The variations of the dielectric constant, the dielectric loss, and AC conductivity with variation in frequency and temperature for YSZ nanoparticles were analyzed. The

The test result shows that the specimen joint with 10µ Zn interlayer has higher mechanical properties than samples made with 5µ, 10µ, 20µ, 40µ and 100µ Zn interlayer.. To analyze

was based on analyses of difuse relectance and colorimetric coordinates and focused in the energy levels of the Pr 3+ ions.. It should be emphasized that no publication was found in
