Diffusivity in the A- and B-sites CaMnO3 polycrystalline perovskite-δ-deficient Ca and spinel CaMn2O4 (marokite) as a secondary phase was studied using chemical tracers and secondary
Affinity to water well-defined selection, nanostructured hydroxyapatite (HA) samples were investigated by H (2) O vapor adsorption microcalorimetry and infrared (IR) spectroscopy. A great all
Perovskite-structured materials, because the chemical-physical properties and composition tuneable, have expanded their range of applications for the chemical looping process, in which the lattice oxygen
