Shear-induced material transfer across the core-mantle boundary aided by the post-perovskite phase transition [PDF]
, 2005 We present a novel mechanical model for the extraction of outer core material upwards across the CMB into the mantle side region of D" and subsequent interaction with the post-perovskite (ppv) phase transition.

Size Dependent Ternary Halide Solid Solutions in Perovskite Nanocrystals
Crystalline solid solutions incorporate guest atoms by substituting host lattice sites up to a solubility limit dictated by solute host similarity. Solid solutions enable tuning various material properties, such as the optoelectronic behavior of halide perovskites.

Synthesis and sintering of ceramic nanocomposites with high mixed conductivity [PDF]
Science of Sintering, 2005 Metastable solid solutions of complex oxides with fluorite and perovskite structures are obtained by mechanosynthesis. Dense ceramics on the base of these metastable phases was obtained by thermal sintering of nanopowders due to kinetic stabilization ...

Solid solution behaviour of CaSiO3 and MgSiO3 perovskites [PDF]
Physics and Chemistry of Minerals, 2010 Using density functional simulations within the generalized gradient approximation and projector-augmented wave method together with thermodynamic modelling, the reciprocal solubilities of MgSiO₃ and CaSiO₃ perovskites were calculated for pressures and temperatures of the Earth's lower mantle from 25 to 100 GPa and 0 to 6,000 K, respectively.
