Summary: RP oxides based on La2NiO4+delta show significant hydration and protonic conduction, making them potential positrode materials for PCECs. Unlike other materials, RP oxides can supply protons through interstitial oxide ions and exhibit triple conduction mechanism. Theoretical calculations support proton migration between interstitial oxide ions in the rock-salt layer. Experimental results show that hydration increases with the level and basicity of dopants in La2NiO4+delta and La(2-)(x)A(x)NiO(4+)(delta) (A = Ca, Sr, Ba). Hebb-Wagner blocking electrode measurements demonstrate significant partial protonic conductivity in all samples. The effect of doping on hydration and pH2O on p-type conductivity suggests that protons primarily reside on structural oxide ions, but the role of interstitial oxide ions cannot be ruled out in cases with oxygen excess. These findings provide insights for further study and optimization of RP oxides as positrode materials for PCECs.

Summary: A new strategy involving the formation of Ruddlesden-Popper (RP)-single perovskite (SP) nanocomposites has been introduced to enhance the cathodic performance of protonic ceramic fuel cells (PCFCs). The synergy between RP and SP in the nanocomposites improves oxygen reduction activity and proton conductivity, leading to significant performance improvements. Specifically, the integration of LSCF2.7 cathode and BZCY172 electrolyte results in an attractive peak power output of 391 mW cm(-2) at 600 degrees C.

Summary: Nonvolatile optoelectronic memories based on ambipolar SnO transistors with multibit memory behavior and ultralong retention time are achieved using an Al2O3/2D PVK heterostructure dielectric architecture. The storage characteristics are attributed to suppressed gate leakage by the Al2O3 layer and hopping-like ionic transport in 2D PVK with varying activation energy. This study provides valuable insights into PVK-based dielectric engineering for information storage and enables the development of multilevel broadband-response optoelectronic memories.

Summary: This study reports a new Ruddlesden-Popper (R-P) structure oxide, which is widely used as the electrode material in low temperature solid oxide fuel cells (LT-SOFCs) due to its high catalytic activity and excellent oxygen transport performance. However, there are few reports on its application as the electrolyte material in LT-SOFCs. The researchers prepared a P-N heterostructure by using R-P P-type semiconductor Sm1.2Sr0.8Ni0.6Fe0.4O4+5 (SSNF) oxide material as the electrolyte and N-type semiconductor Sm0.075Nd0.075Ce0.85O2-5 (SNDC) oxide material as the cathode. The 5SSNF-5SNDC composite electrolyte exhibited a high ionic conductivity of 0.201 S.cm-1 and a remarkable fuel cell power density of 1056 mW.cm-2 at 550℃. The results indicate that P-N heterojunctions constructed from oxide materials with highly catalytically active R-P structures exhibit excellent electrolyte performance. This work provides a new perspective for developing advanced electrolytes of LT-SOFCs.

Summary: By engineering A-site cation deficiencies, the CO2 electroreduction properties of Cu-based RP perovskite oxides can be greatly enhanced, with specific relationships between selectivity and activity demonstrated at different levels of cation deficiencies. Such optimized properties are attributed to the introduction of oxygen vacancies and CuO/RP hybrids induced by the cation deficiencies, leading to improved adsorption/activation of key reaction species and manipulated reaction pathways.

Summary: This study investigated the possibility of introducing cation vacancies into the Ln sublattice of perovskite-related Ruddlesden-Popper nickelates. The results showed that the concentration of cation vacancies in the A sublattice of the Ruddlesden-Popper structure is very low, and the introduction of vacancies enhances the diffusivity of A-site cations and destabilizes the structure. However, the nominal cation deficiency has no effect on the electrical conductivity and oxygen permeability of the ceramics.

Summary: Complex oxides Ba1+xLa1-xIn0.5Y0.5O4-0.5x with a Ruddlesden-Popper block-layered structure are successfully obtained for the first time. Dissociative absorption of water from the gas phase is observed, and energetically nonequivalent OH- groups are found to be the only form of oxygen-hydrogen groups. It is shown that joint iso- and heterovalent doping of cationic sublattices significantly enhances the proton concentration in hydrated samples, which is beneficial for proton transfer.

The experimental investigation revealed that substituting half of the In3+ ions with Y3+ ions in the two-layer perovskite BaLa2In2O7 leads to increased oxygen ion conductivity due to enhanced mobility resulting from an increase in interlayer space. The increase in proton conductivity was attributed to both improved proton mobility and concentration. BaLa2InYO7 exhibited predominantly proton conductivity at temperatures below 500 degrees C.
