Noise Fingerprints as a Quantitative Order Parameter for Polarization‐ and Defect‐Mediated Switching in Hafnia Ferroelectrics

Advanced Science, EarlyView.
Low‐frequency noise fingerprints in hafnia ferroelectrics provide a quantitative handle to resolve the long‐standing debate between polarization‐mediated and defect‐mediated switching. By tuning oxygen vacancy density via ALD O3 dose time and applying a physically constrained deconvolution, we extract bias‐resolved current fractions for both mechanisms

Polyoxometalate as Hydrogen–Electron Hub in Metal–Organic Complex for Electrocatalytic Nitrate Reduction to Ammonia

Advanced Science, EarlyView.
To tackle low electrocatalytic nitrate reduction to ammonia efficiency in neutral media, this work designs chain‐like dinuclear/trinuclear polyoxometalate‐based metal‐organic complexes. Metal clusters provide nitrate adsorption/activation sites, while polyoxometalates (POMs) drive water dissociation to generate active hydrogen (*H) that migrates to ...

Integrated Ultrasound Device for Precision Bladder Volume Monitoring via Acoustic Focusing and Machine Learning

Advanced Science, EarlyView.
We present a conformable wearable ultrasound patch for noninvasive bladder volume monitoring. A flexible PZT array combined with a concave acoustic lens concentrates acoustic energy and improves depth selectivity through the anterior pelvic wall.

Electron‐Phonon Interactions Facilitating Large Polaron‐Related Charge‐Carrier Dynamics for Efficient Perovskite Nanocrystal Solar Cells

Advanced Science, EarlyView.
We developed a custom‐synthesized ligand, 2‐thiophenepropenammonium iodide, to exchange the native ligands capped on inorganic perovskite nanocrystals (NCs), and identified that the significantly decreased strength of electron‐phonon interaction benefited the charge‐carrier dynamics in their assembled films.
