Computer simulations of iron in magnesium silicate perovskite [PDF]

open access: yes, 2008
We use atomistic computer simulation techniques to investigate the site partitioning of iron in (Mg,Fe)SiO_{3} perovskites. Our calculations predict that the most energetically favourable reaction for iron substitution will be a direct exchange of Fe^{2+}

Electroluminescence in perovskite oxide nanocrystals [PDF]

open access: yesAIP Advances, 2020
Chemically stable and easily printable inorganic surface-emitting devices are essential for portable, disposable, outdoor-safe, and wearable information display devices. However, inorganic electroluminescent devices with both chemical stability and printability have never been realized.

Perovskite-type oxide catalysts.

open access: yesHyomen Kagaku, 1990
ペロブスカイト型酸化物の触媒特性と表面特性との関連について解説する。ペロブスカイト型酸化物上で起こる触媒反応の機構は, 吸着種間の反応が重要な “Suprafacial” 機構と, バルク酸素が反応に関与する “Intrafacial”機構に分類される。炭化水素の水素化, 水素化分解反応や比較的低温で起こるCO酸化反応が前者の機構で進行し, 反応基質の吸着に対する表面, 特にBサイト遷移金属の電子状態が重要である。一方, 完全酸化 (燃焼) 反応, NO還元反応, NO分解反応などは後者の機構で進行する。この場合, 格子酸素の反応性や酸素欠陥の存在などのバルクの性質が重要ではあるが, ペロブスカイト型酸化物の表面状態や組成は変化しやすいために ...

Synthesis of oxyanion-doped barium strontium cobaltferrites: stabilization of the cubic perovskite and enhancement in conductivity [PDF]

open access: yes, 2012
In this paper we demonstrate the successful incorporation of oxyanions (borate, phosphate) into Ba1ySryCo0.8Fe0.2O3−δ (BSCF) cathode materials. For low levels of dopant, a small enhancement in the conductivity was observed; e.g.

Superconductivity in the non-oxide perovskite MgCNi3 [PDF]

open access: yesNature, 2001
The oxide perovskites are a large family of materials with many important physical properties. Of particular interest has been the fact that this structure type provides an excellent structural framework for the existence of superconductivity. The high Tc copper oxides are the most famous examples of superconducting perovskites, but there are many ...

Designing Optimal Perovskite Structure for High Ionic Conduction. [PDF]

open access: yes, 2020
Solid-oxide fuel/electrolyzer cells are limited by a dearth of electrolyte materials with low ohmic loss and an incomplete understanding of the structure-property relationships that would enable the rational design of better materials.
