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.

The development of alternative cathodes for high temperature solid oxide electrolysis cells [PDF]

, 2015
This study mainly explores the development of alternative cathode materials for the electrochemical reduction of CO₂ by high temperature solid oxide electrolysis cells (HTSOECs), which operate in the reverse manner of solid oxide fuel cells (SOFCs).

Dielectric properties of CaCu3Ti4O12 based multiphased ceramics [PDF]

, 2006
A “soft chemistry” method, the coprecipitation, has been used to synthesize the perovskite CaCu3Ti4O12 (CCT). Three main types of materials were obtained for both powders and sintered ceramics: a monophased consisting of the pure CCT phase, a biphased ...

Akimotoite to perovskite phase transition in MgSiO3 [PDF]

, 2004
The akimotoite to perovskite phase transition of MgSiO3 is shown by first principles calculations to have a negative Clapeyron slope, consistent with experimental observations.

Manganese titanium perovskites as anodes for solid oxide fuel cells [PDF]

, 2008
A new family of perovskite titanates with formulae La4+nSr8-nTi12-nMnnO38 and La4Sr8Ti12-nMnnO38-δ have been investigated as potential fuel electrode materials for SOFCs. The series La4+nSr8-nTi12-nMnnO38 present layered domains within their structure.

Tantalum Oxide as an Efficient Alternative Electron Transporting Layer for Perovskite Solar Cells

Nanomaterials, 2022
Electron transporting layers facilitating electron extraction and suppressing hole recombination at the cathode are crucial components in any thin-film solar cell geometry, including that of metal–halide perovskite solar cells.
