Expansion Force‐Based Adaptive Multistage Constant Current Fast Charging with Lithium Plating Detection for Lithium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
This article presents an adaptive multistage constant current (MCC) charging method for lithium‐ion batteries, using expansion force feedback to detect lithium plating in real time. It outlines how force‐derivative thresholds enable self‐regulation of the charging rate, increasing speed by 50% without damage.

Probing Anisotropic Quasiparticle Dynamics and Topological Phase Transitions in Quasi‐1D Topological Insulator ZrTe5

open access: yesAdvanced Science, EarlyView.
This study reveals quasiparticle dynamics in ZrTe5. Polarization‐dependent measurements show transient reflectivity anisotropy arises from electron relaxation and lattice vibrations. The first dynamical evidence of a temperature‐induced Lifshitz transition is reported.

A Generative AI‐Assisted Piezo‐MEMS Ultrasound Device for Plant Dehydration Monitoring

open access: yesAdvanced Science, EarlyView.
This study introduces a complementary metal–oxide–semiconductor (CMOS)‐compatible wearable piezoelectric micromachined ultrasound transducers (PMUTs) that sandwiches the leaf (PMUT–Leaf–PMUT, PLP) and employs generative artificial intelligence for real‐time analysis.
