      abstract     = {$\alpha$-MnO$_{2}$ nanorods were synthesized via the
                      hydrothermal decomposition of KMnO$_4$ in an acidic
                      environment in the presence of Co$^{2+}$ and Cr$^{3+}$ ions.
                      Reactions were carried out at three different temperatures:
                      90, 130 and 170 °C. All prepared samples exhibit a
                      tetragonal MnO$_2$ crystalline phase. SEM–EDS analysis
                      shows that cobalt cations are incorporated to a higher
                      degree into the MnO$_2$ framework than chromium ions, and
                      that the content of the dopant ions decreases with
                      increasing reaction temperature. The oxidation of Co$^{2+}$
                      to Co$^{3+}$ during the reaction was proved by an XANES
                      study, while EXAFS results confirm that both dopant ions
                      substitute Mn$^{4+}$ in the center of an octahedron. The
                      K/Mn ratio in the doped samples synthesized at 170 °C is
                      significantly lower than in the undoped samples. Analysis of
                      an individual cobalt-doped $\alpha$-MnO$_{2}$ nanorod with
                      HAADF-STEM reveals that the distribution of cobalt through
                      the cross-section of the nanorod is uniform. The course of
                      thermal decomposition of the doped nanorods is similar to
                      that of the undoped ones. Dopant ions do not preserve the
                      MnO$_2$ phase at higher temperatures nor do they destabilize
                      the cryptomelane structure.},
