Stabilized Intermediate Phase Via Pseudo‐Halide Anions Toward Highly Efficient and Light‐Soaking Stable Perovskite Solar Cells

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The formate pseudo‐halide anion is strategically introduced at the buried interface to stabilize the intermediate phases formed during perovskite crystallization. The controlled crystallization enhances crystallinity and alleviates tensile strain, eliminating residual PbI2 near the buried interface.

Extracorporeal Catalytic Hemoperfusion Therapy for Refractory Septic Shock Using Ceria Nanoparticle‐Embedded Porous Microbeads

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces an extracorporeal hemoperfusion system incorporating porous microbeads embedded with autocatalytic ceria nanoparticles (CeNPs) for targeted reactive oxygen species (ROS) scavenging in septic shock. The blood‐compatible hemoperfusion cartridge demonstrated significant improvements in survival, hemodynamic stability, and organ ...

Nano‐Patterned CuO Nanowire Nanogap Hydrogen Gas Sensor with Voids

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
Sub‐5‐ppb hydrogen (H2) detection and sub‐10‐s response and recovery times are achieved based on nano‐patterned polycrystalline CuO nanowires nanogap gas sensors with voids using electron‐beam lithography and unique annealing processes. Pre‐H2 annealing, void‐generating oxidation, and downscaled nanogap electrodes are key to improving the sensing ...
