Hierarchical Physical‐Cyber Encryption via Metasurface‐Encoded Holographic Keys

Advanced Science, EarlyView.
ABSTRACT Physical‐layer encryption based on metasurfaces has emerged as a promising alternative to conventional algorithmic cryptography by embedding security into physical processes. However, most existing metasurface‐based encryption schemes operate within single‐stage or static frameworks, where correct physical illumination directly reveals the ...

Soft, Multi‐Wavelength Photoplethysmography Enables Reliable Neonatal Blood Pressure Monitoring Via Error Stratification

Advanced Science, EarlyView.
A soft hybrid multi‐wavelength PPG wearable acquires neonatal signals. Synchronized PPG and invasive ABP data are segmented into fixed windows. A 1D‐EfficientNet model predicts segment‐level SBP and DBP. Model performance is examined with retrospective subgroup analysis across acquisition conditions.

Green and Scalable Synthesis of Efficient and Stable CsPbBr3 Perovskite Quantum Dots Enables Low‐Threshold Amplified Spontaneous Emission

Advanced Science, EarlyView.
Green and scalable synthesis of CsPbBr3 perovskite quantum dots using bio‐sourced lecithin and hexane enables single‐batch production over 10 grams. Suppressed Auger recombination and electron‐phonon coupling yields 95% PLQY, enhanced stability, and low ASE thresholds of 230.4 (ns) and 50.1 (fs) µJ cm−2 in neat films. ABSTRACT Halide perovskite quantum
