AbstractSpatiotemporal control of full freedoms of polarized light emission is crucial in multiplexed optical computing, encryption and communication. Although recent advancements have been made in active emission or passive conversion of polarized light through solution-processed nanomaterials or metasurfaces, these design paths usually encounter limitations, such as small polarization degrees, low light utilization efficiency, limited polarization states, and lack of spatiotemporal control.

Multi-functional perovskite oxide Pr0.6Sr0.4Mn0.2Fe0.7Ni0.1O3−δ as an efficient quasi-symmetric electrode for solid oxide fuel/electrolysis cells† Solid oxide cells (SOCs) have recently gained attention as an efficient energy conversion system for a smart-grid that can resolve the intermittency of renewable energy. In particular, a symmetric configuration of the electrode has been developed to minimize fabrication cost and relieve compatibility issues.
