| Sumario: | Powder XRD analysis of as-synthesized Ca3Co4O9 materials; SEM and (HR-)TEM images of (CaCoO2)–(CoO2) nanotubes as-synthesized and annealed at 200 °C; STEM-ADF images and extra SR-EELS data recorded in one of these NTs; TEM images of partially rolled CaCoO2–CoO2 nanotubes synthesized in hydrothermal conditions at 200 °C for 4 h; TEM images of NaOH-intercalated Ca3Co4O9 nanotubular structures accomplished by sonication in the presence of NaOH; atomic positions and lattice vectors for the relaxed (CaCoO2)–(CoO2)2 and (Ca2CoO3)2–(CoO2)3 supercell structures, respectively; number of valence electrons and the magnetization for each atom in these structures, calculated by integration over Bader volumes; spin-resolved total density of states projected over the d orbitals of these Co atoms for (CaCoO2)–(CoO2)2 supercell and for the individual CaCoO2 and CoO2 layers. |
