Lattice defects significantly affect the mechanical properties of crystalline metal oxides. The materials for components solid oxide fuel cells (SOFCs) are no exception, and hence understanding interplay between lattice is important to ensure stability SOFCs. Herein, we performed an in situ evaluation temperature P(O2) dependence elastic moduli La2NiO4 (LN214), a candidate cathode material SOFC...

The influence of the different types oxygen on structure and electrical conductivity perovskite-type nickelates were investigated. La2NiO4+δ, La0,6Sr1,4NiO4–δ, Sr3Al0,75Ni1,25O7–δ synthesised using solidstate reaction route. Phase composition was determined by X-ray powder diffraction analysis. iodometric titration technique used to specify content powders. Oxygen desorption absorption, includi...

Valence change memories, in which internal redox reactions control the resistance are promising candidates for resistive random access memories (ReRAMs) and neuromorphic computing elements. In this context, La2NiO4+? (L2NO4), a mixed ionic-electronic conducting oxide, well known its highly mobile oxygen interstitial ions, emerges as potential switching material novel L2NO4-based memristive devi...

Photocatalysis and photoelectrocatalysis, as green low-cost pollutant treatment technologies, have been widely used to simultaneously degrade pollutants produce clean energy solve the problems of environmental pollution crisis. However, disadvantages photocatalysts in a narrow absorption range low utilization rate solar still hinder practical application. Here we fabricate two-dimensional porou...
