      abstract     = {The microstructural and compositional homogeneity of
                      La0.99Ca0.01Nb0.99Ti0.01O4−δ and
                      La0.99Sr0.01Nb0.99Al0.01O4−δ proton conductors was
                      studied using the combination of atomic-resolution scanning
                      transmission electron microscopy (STEM), electron energy
                      loss spectroscopy (EELS) and STEM image simulations. The
                      obtained results revealed that gently doped proton
                      conductors were predominantly composed of grains with a
                      monoclinic lanthanum niobate crystal structure. In addition
                      to the host phase, dopant-rich phases were also observed and
                      identified. The La0.99Sr0.01Nb0.99Al0.01O4−δ matrix
                      accommodated dopant-rich grains retaining an LaAlO3 cubic
                      crystal structure with a significant fraction of Sr
                      incorporated into them. The secondary phases embedded in the
                      La0.99Ca0.01Nb0.99Ti0.01O4−δ matrix possessed the
                      pyrochlore La2Ti2O7 crystal structure with Ca partially
                      substituting La. High spatial resolution EELS revealed
                      preferential Ca sites within the pyrochlore La2Ti2O7 crystal
                      lattice. The origin of the secondary phase formation and the
                      role of these phases for the transport properties of
                      co-doped lanthanum niobates are discussed here.},
