• Expanded chemistry and proton conductivity in vanadium-substituted variants of γ-Ba4Nb2O9 

      Brown, Alex J; Schwaighofer, B; Avdeev, Maxim; Johannessen, B; Evans, I R; Ling, Chris D
      Published 2021
      We have substantially expanded the chemical phase space of the hitherto unique γ- Ba4Nb2O9 type structure by designing and synthesising stoichiometric ordered analogues γ- Ba4V1/3Ta5/3O9 and γ-Ba4V1/3Nb5/3O9, and exploring ...

    • Synthesis and crystal structures of two polymorphs of Li4–2xMg1+xTeO6 

      Brown, Alex J; Liu, Jiatu; Marlton, Frederick P; Avdeev, Maxim; Kennedy, Brendan J; Ling, Chris D
      Published 2020
      Two polymorphs of lithium magnesium tellurate Li4–2xMg1+xTeO6 have been prepared by solid-state reactions and their crystal structures characterised by powder X-ray and neutron diffraction. For x  0, a monoclinic C2/m ...

    • Synthesis-controlled polymorphism, magnetic and electrochemical properties of Li3Co2SbO6 

      Brown, Alex J; Xia, Qingbo; Avdeev, Maxim; Kennedy, Brendan J; Ling, Chris D
      Published 2019
      Li3Co2SbO6 is found to adopt two highly distinct structural forms: a pseudohexagonal (monoclinic C2/m) layered O3-LiCoO2 type phase with “honeycomb” 2:1 ordering of Co and Sb; and an orthorhombic Fddd phase, isostructural ...
