Thermal Enhancement of TADF‐OLED Performance: Size of Active Area Matters

Advanced Materials Interfaces, EarlyView.
Large‐area TADF‐based OLEDs can be used as thermally assisted light‐emitting devices, in which moderate waste heat can partially compensate for efficiency losses associated with increasing active area. ABSTRACT Temperature significantly impacts the performance of light‐emitting diodes, typically causing degradation as they heat up. However, OLEDs using

Surrogate‐Optimized Flow‐Guided Miniature Condenser for Rapid Exhaled Glucose Detection

Advanced Materials Technologies, EarlyView.
A surrogate‐optimized miniature condenser guides humid exhaled flow toward cold surfaces to accelerate exhaled breath condensate collection. By improving vapor access within a compact footprint, the design increases sample yield. This enables post‐collection enrichment and rapid colorimetric glucose detection from dilute exhaled biomarkers within a 5 ...
