  This study evaluates the redox energetics of LaMO3−δ (M=Sc–Cu) perovskite-type oxides via generalized gradient approximation (GGA) to DFT. Two different approaches to redox energetics of oxygen deficient perovskites of strongly non-stoichiometric (δ=0.5) and dilute defect limits (δ→0) are studied. In the first approach the enthalpies of oxidation are calculated using the stoichiometric end-compounds of LaMO3 and LaMO2.5. The most common structures for the reduced lanthanides and strontides similar to the ones experimentally reported for SrMnO2.5, SrFeO2.5, and LaNiO2.5 are considered. The second approach to the oxidation enthalpies termed (δ→0) follow the trend observed experimentally. This approach represents the experimental conditions of the measured oxygen enthalpies, and is hampered less by the artificial features due to spurious self-interaction errors in GGA.

  The generalized gradient approximation to density functional theory is benchmarked for the calculation of formation enthalpies of lanthanide perovskite-type oxides LaMO3 (M = Sc–Cu). Three different reaction pathways (from elements, mono and sesquioxides) have been investigated and the systematic errors associated with electron correlation due to overbinding of the oxygen molecule, electron self-interaction within localized 3d states, and geometrical relaxations are analyzed by critical comparison with a large number of experimental data. Calculated formation enthalpies from elements and sesquioxides are in good agreement with experiment when the overbinding of O2 is corrected for using the Wang ad hoc factor of 131 kJ mol−1 O2. By contrast, the calculated formation enthalpies from monoxides are systematically too low which are attributable to strong self-interactions due to localized 3d states in MO. The effects of relaxation and choice of magnetic structure on the enthalpies of formation are analyzed.

  The liquidus field of Ca-perovskite (cpv, composition close to CaSiO3) expands with increasing pressure, making cpv the last residual phase during partial melting of recycled oceanic crust (ROC) of basaltic composition. Because ROC is denser and has lower solidus temperature than ambient mantle peridotite, ROC slivers might sink relative to peridotite in the lateral core-mantle boundary flow towards the Large Low Shear-wave Velocity Provinces (LLSVPs) and undergo partial melting in the hot regions near the LLSVP-margins. The root zones of major mantle plumes, commonly located near the LLSVP margins, tend to coincide with ultra-low velocity zones (ULVZs). The refractory nature of high-density cpv in ROC and highly elevated Fe/Mg-ratios of the partial melts may cause separation of sinking melts and cpv from rising iron-poor post-bridgmanite and seifertite. The composition for the partially molten ULVZs directly above the core-mantle boundary may therefore involve refractory cpv in equilibrium with an interstitial Fe-rich silicate melt and tiny fractions of Fe-dominated metallic melt. Because such a composition would approach equilibrium with the outer core, the ULVZs may be "partially open windows" between the core and mantle. Cpv was probably also incorporated into dense cumulates dominated by Fe-rich bridgmanite and ferropericlase, formed during late-stage crystallization of a basal magma ocean. Such cumulates might be an essential part of the two antipodal LLSVPs, in addition to basaltic ROC. Because of the high cpv-melt partitioning coefficient for the radioactive elements, U and Th (may exceed 10), the source of the primordial He and solar Ne isotopic compositions in deep-rooted plumes is unlikely to be either ULVZ- or LLSVP-material.

  Hydrogen will play a key role in a zero-emission society, and proton (H+) conducting oxides have gained interest as solid-state electrolytes for next-generation electrochemical devices for fuel cells and electrolyzers. Understanding the effect of structure on materials functional properties is important for enhancing the performance of such electrolytes. Oxides with fluorite related crystal structures are interesting for their high oxide ion and proton (H+) conductivities, and in this work the relationship between the atomic structure and the materials properties such as ionic conductivity and hydration properties have been studied for three different oxides. They are oxygen deficient with respect to the fluorite structure and the vacant oxide ion sites can thus be ordered or disordered. Through a combination of different experimental and computational methods the nature and degree of ordering and the atomic structure have been determined, and correlated to the properties of the cations present, such as size and electronegativity. The work further focuses on whether ordering the oxide ion vacancies affects the hydration and consequently the proton conductivity. The results have led us to propose a new model for hydration of heavily doped yet disordered fluorite oxides.
