Synergized Tri‐Phase Anode via Purposive Ba2+ Doping at the La3+ Site in LaFe0.7Ni0.3O3‐δ for Improved SOFC Performance

open access: yesAdvanced Science, EarlyView.
Purposive doping of low electronegative Ba2+ (0.89) at La3+ (1.1) site in LaFe0.7Ni0.3O3‐δ induces the formation of a tri‐phase composite, which shortens Fe─O bond and lowers activation energy, thereby significantly improves electrical conductivity and catalytic activity, and finally offers a record‐high peak power density in La0.5Ba0.5Fe0.7Ni0.3O3‐δ ...

Temperature‐Driven Emission Redistribution of Yb2+ in SrB4O7 Enables Highly Sensitive Optical Thermometry Supported by Multiple Linear Regression

open access: yesAdvanced Science, EarlyView.
A novel optical thermometer exploits the rare UV emission of Yb2+ ions in a SrB4O7 host, enabling highly sensitive, non‐contact temperature measurements from 80 to 420 K. The applied multiple linear regression (MLR) analysis results in a multiple increase in the resulting temperature sensitivity.

Stress‐to‐Light Conversion in an Earth‐Abundant Oxide Semiconductor

open access: yesAdvanced Science, EarlyView.
Stress‐to‐light conversion in solids represents a unique photonic functionality, yet it has never been realized in a chemically simple and sustainable material. Here, we show that sustainable semiconductor ZnO exhibits strong near‐infrared (NIR) luminescence under elastic stress when defect‐engineered to stabilize the p‐type state.

Asymmetric Electrostrain/Electrobending in Piezoelectric Ceramics: Role of Defect Dipoles or Oxygen Vacancies

open access: yesAdvanced Science, EarlyView.
Defect‐configurational origins of the asymmetric apparent electrostrain are revealed in different piezoelectric ceramics via atomic‐scale visualization of defect configurations. Migration of oxygen vacancies leads to the electrobending effect in N2‐sintered BaTiO3, while defect dipoles in Ba0.99TiO2.99 generate true asymmetric electrostrain without ...
